To determine whether the presence of an ultrasound hypoechoic region at the site of a region of interest (ROI) on magnetic resonance imaging (MRI) results in improved prostate cancer (PCa) detection and predicts clinically significant PCa on MRI–ultrasonography fusion‐targeted prostate biopsy (MRF‐TB).
Materials and Methods
Between July 2011 and June 2017, 1058 men who underwent MRF‐TB, with or without systematic biopsy, by a single surgeon were prospectively entered into an institutional review board‐approved database. Each MRI ROI was identified and scored for suspicion by a single radiologist, and was prospectively evaluated for presence of a hypoechoic region at the site by the surgeon and graded as 0, 1 or 2, representing none, a poorly demarcated ROI‐HyR, or a well demarcated ROI‐HyR, respectively. The interaction of MRI suspicion score (mSS) and ultrasonography grade (USG), and the prediction of cancer detection rate by USG, were evaluated through univariate and multivariate analysis.
Results
For 672 men, the overall and Gleason score (GS) ≥7 cancer detection rates were 61.2% and 39.6%, respectively. The cancer detection rates for USGs 0, 1 and 2 were 46.2%, 58.6% and 76.0% (P < 0.001) for any cancer, and 18.7%, 35.2% and 61.1% (P < 0.001) for GS ≥7 cancer, respectively. For MRF‐TB only, the GS ≥7 cancer detection rates for USG 0, 1 and 2 were 12.8%, 25.7% and 52.0%, respectively (P < 0.001). On univariate analysis, in men with mSS 2–4, USG was predictive of GS ≥7 cancer detection rate. Multivariable regression analysis showed that USG, prostate‐specific antigen density and mSS were predictive of GS ≥7 PCa on MRF‐TB.
Conclusions
Ultrasonography findings at the site of an MRI ROI independently predict the likelihood of GS ≥7 PCa, as men with a well‐demarcated ROI‐HyR at the time of MRF‐TB have a higher risk than men without.
Sampling of prostate tissue to confirm pathologically a clinical suspicion of cancer has undergone an exponential change. The random systematic prostate biopsy technique was the only method used for many decades, initially guided by the finger but, since 1989, performed with TRUS guidance. Now, within the space of only a few years, we have entered the era of performing prostate biopsies on the basis of high‐tech three‐dimensional multiparametric MRI images, including software that can track the exact course of the biopsy needle [1]. While new technical developments in general lead to better, more individually directed healthcare, there is always the risk of abandoning ‘old’ but well developed and extensively tested techniques too soon. In this issue of the BJUI, Press et al. [2] looked at the added value of the presence of an ‘old‐fashioned’ TRUS‐detected lesion in cancer‐suspicious regions on MRI to better predict the presence of clinically significant prostate cancer (csPCa) defined as Gleason score ≥7. In their study comprising 1058 men, it was shown that a well‐demarcated abnormal TRUS finding noted at the time of MRI‐TRUS fusion‐guided prostate biopsy coincides with an increased risk of csPCa detection, independent of MRI suspicion (Prostate Imaging Reporting and Data System [PI‐RADS] score).
Increasing PI‐RADS score is correlated with an increased percentage of csPCa after targeted biopsy, both at initial and repeat biopsy. In a review based on data from 8252 men, it was shown that there is a gradual increase in the detection of csPCa from PI‐RADS 3 to PI‐RADS 4 to PI‐RADS 5 index lesions. For example, at first biopsy, the overall rate of PCa detection and the percentage of csPCa were 39%, 62% and 92% and 54%, 63% and 76% for PI‐RADS 3, 4 and 5 lesions, respectively. This means that in men with PI‐RADS 3 lesions, representing approximately one‐third of men deemed eligible for further assessment, only 39% will be diagnosed with PCa and half of the PCa detected will be potentially indolent Gleason 6 PCa [3]. This makes this group of men extremely interesting for further risk stratification before biopsy. Multivariable risk stratification in which PSA density plays an important role has been shown to be of value in these men [4] but further refinement could potentially be made by including suspicious lesions identified at TRUS.
Apart from the added value of TRUS findings in terms of risk stratification, the performance of the MRI‐targeted biopsy itself could be improved by visual guidance of hypoechoic lesions. In the present study by Press et al [2], a hypoechoic TRUS lesion was present at or near the location of two‐thirds of cancer‐suspicious lesions on MRI. The authors more or less advise to direct the targeted biopsy cores not only to the MRI suspicious lesion, but also the TRUS suspicious lesion, both of which often do not fully overlay in a software‐assisted MRI‐TRUS fusion model. The extent to which this ‘correction for misregistration’ is already included during targeted biopsy in current clinical practice is unknown. Although feasible and seemingly important during software‐assisted fusion targeted biopsy, TRUS lesions in cancer‐suspicious MRI regions might be more frequently targeted during cognitive fusion‐targeted biopsy. Two recent studies underline the important message of the present study, and show that a considerable proportion of csPCa is missed in and around MRI‐suspicious lesions by targeted biopsies, as a result of sampling errors related to both misregistration and intra‐tumour heterogeneity [5, 6]. As suggested by these studies, visual guidance by hypoechoic lesions and ‘focal saturation’ biopsy by additional (peri‐)lesional cores might improve the detection of csPCa.
In summary, ‘good old’ TRUS could be of value in those patients who are virtually always present in scenarios in which a grading system is being used, i.e. patients belonging to the so‐called grey zone. The challenge of risk stratification (i.e. personalized medicine) is to nibble at both sides of the grey zone by implementing new techniques or, more likely by implementing a combination of all available and relevant knowledge.

To report outcomes from a multiparametric (mp) magnetic resonance imaging (MRI)‐based active surveillance programme that did not include performing protocol biopsies after the first confirmatory biopsy.
Patients and Methods
All patients diagnosed with Gleason 3 + 3 prostate cancer because of a raised PSA level who underwent mpMRI after diagnosis were included. Patients were recorded in a prospective clinical database and followed up with PSA monitoring and repeat MRI. In patients who remained on active surveillance after the first MRI (with or without confirmatory biopsy), we investigated PSA dynamics for association with subsequent progression. Comparison between first and second MRI scans was undertaken. Outcomes assessed were: progression to radical therapy at first MRI/confirmatory biopsy and progression to radical therapy in those who remained on active surveillance after first MRI.
Results
A total of 211 patients were included, with a median of 4.2 years of follow‐up. The rate of progression to radical therapy was significantly greater at all stages among patients with visible lesions than in those with initially negative MRI (47/125 (37.6%) vs 11/86 (12.8%); odds ratio 4.1 (95% CI 2.0–8.5), P < 0.001). Only 1/56 patients (1.8%) with negative initial MRI scans who underwent a confirmatory systematic biopsy had upgrading to Gleason 3 + 4 disease. PSA velocity was significantly associated with subsequent progression in patients with negative initial MRI (area under the curve 0.85 [95% CI 0.75–0.94]; P <0.001). Patients with high‐risk visible lesions on first MRI who remained on active surveillance had a high risk of subsequent progression 19/76 (25.0%) vs 9/84 (10.7%) for patients with no visible lesions, despite reassuring targeted and systematic confirmatory biopsies and regardless of PSA dynamics.
Conclusion
Men with low‐risk Gleason 3 + 3 prostate cancer on active surveillance can forgo protocol biopsies in favour of MRI and PSA monitoring with selective re‐biopsy.

To determine whether replacement of protocol‐driven repeat prostate biopsy (PB) with multiparametric magnetic resonance imaging (mpMRI) ± repeat targeted prostate biopsy (TB) when evaluating men on active surveillance (AS) for low‐volume, low‐ to intermediate‐risk prostate cancer (PCa) altered the likelihood of or time to treatment, or reduced the number of repeat biopsies required to trigger treatment.
Patients and Methods
A total of 445 patients underwent AS in the period 2010–2016 at our institution, with a median (interquartile range [IQR]) follow‐up of 2.4 (1.2–3.7) years. Up to 2014, patients followed a ‘pre‐2014’ AS protocol, which incorporated PB, and subsequently, according to the 2014 National Institute for Health and Care Excellence (NICE) guidelines, patients followed a ‘2014–present’ AS protocol that included mpMRI. We identified four groups of patients within the cohort: ‘no mpMRI and no PB’; ‘PB alone’; ‘mpMRI ± TB’; and ‘PB and mpMRI ± TB’. Kaplan–Meier plots and log‐rank tests were used to compare groups.
Results
Of 445 patients, 132 (30%) discontinued AS and underwent treatment intervention, with a median (IQR) time to treatment of 1.55 (0.71–2.4) years. The commonest trigger for treatment was PCa upgrading after mpMRI and TB (43/132 patients, 29%). No significant difference was observed in the time at which patients receiving a PB alone or receiving mpMRI ± TB discontinued AS to undergo treatment (median 1.9 vs 1.33 years; P = 0.747). Considering only those patients who underwent repeat biopsy, a greater proportion of patients receiving TB after mpMRI discontinued AS compared with those receiving PB alone (29/66 [44%] vs 32/87 [37%]; P = 0.003). On average, a single set of repeat biopsies was needed to trigger treatment regardless of whether this was a PB or TB.
Conclusion
Replacing a systematic PB with mpMRI ±TB as part of an AS protocol increased the likelihood of re‐classifying patients on AS and identifying men with clinically significant disease requiring treatment. mpMRI ±TB as part of AS thereby represents a significant advance in the oncological safety of the AS protocol.

To assess the chronological changes in urinary incontinence and urethral function before and after radical prostatectomy (RP), and to compare the findings of pelvic magnetic resonance imaging (MRI) before and after RP to evaluate the anatomical changes.
Patients and Methods
In total, 185 patients were evaluated with regard to the position of the distal end of the membranous urethra (DMU) on a mid‐sagittal MRI slice and urethral sphincter function using the urethral pressure profilometry. The patients also underwent an abdominal leak point pressure test before RP and at 10 days and 12 months after RP. The results were then compared with the chronological changes in urinary incontinence.
Fig. 1 Intraoperative view of the apex of the prostate transection line between the urethra and prostate at the normal (straight line) and long urethral stump (dashed line) positions.
Results
The MRI results showed that the DMU shifted proximally to an average distance of 4 mm at 10 days after RP and returned to the preoperative position at 12 months after RP. Urethral sphincter function also worsened 10 days after RP, with recovery after 12 months. The residual length of the urethral stump and urinary incontinence were significantly associated with the migration length of the DMU at 10 days after RP. The residual length of the urethral stump was a significant predictor of urinary incontinence after RP.
Conclusion
This is the first study to elucidate that the slight vertical repositioning of the membranous urethra after RP causes chronological changes in urinary incontinence. A long urethral residual stump reduces urinary incontinence after RP.
Traditionally, MRI of the prostate has been mainly applied in the diagnosis and staging of prostate cancer. Kadono et al. [1] used pre‐ and postoperative pelvic MRI to assess the repositioning of the urethra 10 days and 12 months after prostatectomy, hypothesizing that these alterations could correlate with urinary incontinence and urethral function. Recent MRI measurements of anatomical structures of the pelvic floor, such as membranous urethral length and inner levator distance, were found to be independent predictors of early continence recovery at 12 months after prostatectomy [2] A meta‐analysis has also shown a strong correlation between membranous urethral length and continence recovery at 3‐, 6‐ and 12‐month follow‐up [3] Kadono et al. [1] add another metric to the pelvic floor dimensions that may help predict continence. Cranial migration of the lower end of the membranous urethra early after prostatectomy was associated with urinary incontinence and urinary sphincter function, as objectively assessed by urethral pressure profile. Interestingly, return of the membranous urethra to the more distal preoperative position after 12 months was associated with improvement in continence. In a multivariate model, urethral stump length was a strong predictor of continence outcome at 10 days as well as 12 months after prostatectomy. This observation suggests that urethral length may partly improve post-prostatectomy continence through better compression of the membranous urethra in the pelvic floor membrane rather than through transfer of the intra‐abdominal pressure onto the intra‐abdominally located urethra. If confirmed, this observation may imply that more cranial fixation of the bladder neck in a more intra‐abdominal position may not necessarily improve continence after prostatectomy, in line with data from randomized controlled studies comparing median fibrous raphe reconstruction with standard anastomosis that failed to show a benefit [4,5].
Besides anatomical location, innervation of the proximal urethra is important for post-prostatectomy continence [6]. Kadono et al. found that nerve preservation was an independent predictor of early and long‐term continence outcome, with a b value similar to that of urethral stump length at 12‐month follow‐up. To improve post-prostatectomy continence outcome, proper patient selection seems crucial. In the era of personalized medicine, MRI could be a valuable tool to assess preoperatively the risks of postoperative urinary incontinence and counsel patients accordingly. Avoiding prostatectomy in men with short preoperative membranous urethral length may be an important approach for improving outcome, in particular in light of the fact that many attempts to surgically correct anatomical alignment of the pelvic floor have not clearly improved continence outcome. If surgery is considered, nerve preservation should be performed where possible to improve continence.

Today, Dr Veeru Kasi of University College London, presented the results of the PRECISION (PRostate Evaluation for Clinically Important disease: Sampling using Image-guidance Or Not?) study in the “Game Changing” Plenary session at the #EAU18 Annual Meeting in Copenhagen. The accompanying paper was simultaneously published in the New England Journal of Medicine. And it is stunning! Everyone in the packed eURO auditorium knew they were witness to a practice-changing presentation, and the swift reaction on social media around the world confirms this.
PRECISION: MRI-targeted biopsy strategy leads to fewer men needing biopsy. Article with video interviews with Veeru Kasivisvanathan and Declan Murphy https://t.co/QXaWZLaBvo
— European Association of Urology (EAU) (@Uroweb) March 19, 2018
Congratulations to Veeru (a second year urology resident in London), senior author Dr Caroline Moore, Prof Mark Emberton, and all the collaborators on this multicenter international trial. I had the great privilege to be the Discussant in the Plenary session so have been digesting this study in detail for the past few weeks.
Let me summarise the PRECISION study in brief. In this multicenter international study, 500 men with a suspicion of prostate cancer (mean age 64, median PSA 6.7), were randomised to receive a standard of care (SOC) diagnostic pathway (12 core TRUS biopsy), or an MRI directed pathway. In the MRI pathway, all patients had an MRI, and if the MRI was abnormal (72% of men), they had a targeted biopsy of the lesion(s) (with no systematic biopsy; ie only the abnormal lesion was biopsied). If the MRI was normal (28% of men), they did not have a biopsy, and continued on routine PSA surveillance. The primary outcome was detection rate of clinically significant cancer; and secondary outcomes included the detection rate of clinically insignificant cancer. In the standard of care arm, the detection rate of clinically significant cancer was 26%, and the detection rate of clinically insignificant cancer was 22%. In the MRI pathway, the detection rate of clinically significant cancer was 38%, and the detection rate of taking insignificant cancer was 9%. This is depicted below in one of my summary slides from the plenary discussion.
Therefore, despite the fact that over one quarter of men in the MRI pathway actually avoided a biopsy, the detection rate of clinically significant cancer was much greater in this arm (ie UNDER-diagnosis was reduced). Furthermore, the detection rate of the clinically insignificant cancer was much less (ie OVER-diagnosis was reduced). And all this with a median number of biopsy cores of only four, compared with 12 in the SOC arm. The reduction in core numbers along that too much less complications for these patients.
This looks like WIN-WIN all round!
And I truly believe that these findings should provoke an immediate change in our diagnostic pathway for early prostate cancer in two ways:
All patients with a clinical suspicion of prostate cancer should be offered an MRI as part of their informed/shared decision making pathway
All patients with an abnormality on their MRI scan should be offered be targeted biopsy alone.
The obvious concern of course, is the fate of those patients with a normal MRI (28% of patients), who despite a clinical suspicion of prostate cancer, did not have a biopsy. How many clinically significant cancers might we miss by not offering biopsy to those patients? Of course, we already have an idea of what we would find, as the PROMIS study also included extensive biopsy (transperienal mapping) for patients with a normal MRI.
In PROMIS, the negative predictive value of MRI for detecting any pattern 4 cancer is 76% ie up to 1 in 4 men will have some pattern 4 cancer on transperineal biopsy. However, no primary pattern 4 cancers were missed on MRI. This is something we have to digest. I think that we can accept missing some pattern 4 cancers in some men, provided the “routine follow up” is adequate. But we must also continue to use the other tools we have in our multivariable approach to early detection, and if there are red flags due to family history, palpable nodules, adverse PSA parameters (including PSA density), BRCA mutations, then there will clearly be a role for systematic biopsy in some of these men with normal MRI scans.
In my opinion, we now have enough evidence to fully embrace mpMRI in our approach to early detection of prostate cancer. Following on from the PROMIS study, published in the Lancet 2017, the PRECISION study provides us with the imprimatur to fully embed MRI in the assessment of men with a suspicion of prostate cancer. The era of blind random prostate biopsy is surely over, except perhaps in those patients in whom MRI is contra-indicated. The next challenge will be to create enough capacity and expertise to make this paradigm available to all.
Resourcing will inevitably be an issue, but the PROMIS and PRECISION papers provide a compelling health economic argument for funders. Less men undergoing biopsy; less biopsy cores; less complications; less insignificant cancer – this surely makes economic sense. In Australia, where MRI has already been enthusiastically embraced, a high-quality mpMRI on a 3T machine costs $USD300, and costs are usually borne by patients. In the USA, we hear that a 1.5T MRI (with an endorectal coil) can cost USD$2-3000!! Why is this?! Australia is an expensive country – an iPhone or a da Vinci robot costs 1.5 times the cost in the USA; why therefore should an MRI cost so much in the USA? A symptom of a much broader issue with the bloated US health economy, and likely a barrier to adoption of the paradigm proposed by PRECISION.
So there you have it. A truly practice-changing study. While there will be much discussion about the nuances, I for one will immediately embrace this paradigm:
MRI for all (I already do this)
Targeted biopsy alone for those with MRI lesions (a new departure for me)
No biopsy for those with normal MRI scans (unless there are other red flags).
My concluding slide from the plenary discussion:
Congrats again Veeru, Caroline, Mark and colleagues for publishing this landmark study.
Declan G Murphy
Urologist & Director of Genitourinary Oncology, Peter MacCallum Cancer Centre, Melbourne, Australia
G’day! The 71st annual USANZ Congress, was held in Melbourne and had the biggest attendance on record for the past 6 years. The Urological Nurse’s congress: ANZUNS ran concurrently, encouraging multi disciplinary learning. An excellent and varied educational programme was masterminded by Declan Murphy, Nathan Lawrentschuk and their organising committee. Melbourne provided a great backdrop and soon felt like home with a rich and busy central business district, cultural and sporting venues, the Yarra river flowing past the conference centre, edgy graffiti and hipster coffee shops, plus too many shops, bars and restaurants to visit.
The programme included a day of masterclasses on a range of subjects, including: urological imaging, advanced robotic surgery with a live case from USC, metastatic prostate cancer and penile prosthetics. These were well attended by trainees and consultants alike. The PCNL session (pictured) with Professor Webb was popular and he generously gave his expertise. The session was supported by industry and provided an opportunity to use the latest nephroscopes on porcine models and innovative aids to realistically practice different puncture techniques.
Two plenary sessions were held each morning covering the breadth and depth of urology and were well attended. Dr Sotelo is always a highlight; he presented, to an auditorium of collective gasps, a unique selection of ‘nightmare’ cases His cases gave insight in how intraoperative complications occur and how they can be avoided. Tips, such as zooming out to reassess in times of anatomical uncertainty during laparoscopy or robotic surgery have great impact when you witness the possible consequences. Tim O’Brien shared his priceless insights on performing IVC thrombectomy highlighting the need for preoperative planning, early control of the renal artery and consideration of pre-embolisation. His second plenary on retroperitoneal fibrosis provided clarity on the management of this rare condition highlighting the role of PET imaging and, as with complex upper tract surgery, the importance of a dedicated team.
Tony Costello’s captivating presentation covered several myths in robotic prostate surgery, plus the importance of knowing your own outcome figures and a future where robotics will be cost equivalent to laparoscopy. Future technology, progress in cancer genomics and biomarkers were also discussed in various sessions. One example of new technology was Aquablation of the prostate; Peter Gilling presented the WATER trial results suggesting non-inferiority to TURP. A welcome addition to the programme was Victoria Cullen (pictured), a psychologist and Intimacy Specialist who provides education, support and strategies for sexual rehabilitation. She described her typical consultation with men with sexual dysfunction and how to change worries about being ‘normal’ to focusing on what is important to the individual.
Joint plenary sessions with the AUA and EAU were a particular highlight. Prof Chris Chapple confirmed the need for robust, evidence guidelines which support clinical decision making; and in many cases can be used internationally. He suggested collaboration is crucial between us as colleagues and scientists working in the field of urology. Stone prevention and analysis of available evidence was described by Michael Lipkin; unfortunately stone formers are usually under-estimaters of their fluid intake so encouragement is always needed! Amy Krambeck presented evidence for concurrent use of anticoagulants and antiplatelets during BOO surgery and suggested there can be a false sense of security when stopping these medications as it isn’t always safe. She championed HoLEP as her method of BOO surgery and continues medications, although the evidence does show blood transfusion rate may be higher. She also uses a fluid warming device which has less bleeding and therefore improved surgical vision; importantly it is preferred by her theatres nurses! MRI of the prostate was covered by many different speakers, however Jochen Walz expertly discussed the limitations of MRI in particular relating negative predictive value (pictured). He eloquently explained the properties of cribiform Gleason 4 prostate cancer and how this variant contributed to the incidence of false negatives.
Moderated poster and presentation sessions showcased research and audit projects from the UK, Australia, New Zealand and beyond, mainly led by junior urologists. The best abstracts submitted by USANZ trainees were invited to present for consideration of Villis Marshall and Keith Kirkland prizes. These prestigious prizes were valiantly fought for and reflected high quality research completed by the trainees. Projects included urethral length and continence, no need for lead glasses, obesity and prostate cancer, multi-centre management of ureteric calculi, mental health of surgical trainees and seminal fluid biomarkers in prostate cancer. This enthusiasm for academia will undoubtedly stand urology in good stead for the future; this line up (pictured) is one to watch!
The Trade hall provided a great networking space to be able to meet with friends and colleagues and engage with industry. It also hosted poster presentation sessions, with a one minute allocation for each presenter – which really ensures a succinct summary of the important findings (pictured)! It was nice to meet with Australian trainees and we discussed the highs and lows of training and ideas for fellowships. Issues such as clinical burden and operative time, selection into the specialty, cost of training, burn out and exam fears were discussed and shared universally; however there is such enthusiasm, a passion for urology and inspirational trainers which help balance burdens that trainees face. Furthermore, USANZ ‘SET’ Trainees were invited to meet with the international faculty in a ‘hot seat’ style session which was an enviable opportunity to discuss careers and aspirations.
In addition to the Congress I was fortunate to be invited for a tour and roof-top ‘barbie’ at the Peter Mac Cancer centre; plus a visit to Adelaide with Rick (Catterwell, co-author) seeing his new hospital and tucking into an inaugural Aussie Brunch. Peter Mac and Royal Adelaide Hospital facilities indicated an extraordinary level of investment made by Federal and State providers; the Peter Mac in particular had impressive patient areas, radiotherapy suites and ethos of linking clinical and research. However beyond glossy exteriors Australian public sector clinicians voiced concerns regarding some issues similar to those we face in the NHS.
Despite the distance of travelling to Melbourne and the inevitable jet lag the world does feels an increasingly smaller place and the Urological world even more so. There is a neighbourly relationship between the UK, Australia and New Zealand as evidenced by many familiar faces at USANZ who have worked between these countries; better for the new experiences and teaching afforded to them by completing fellowships overseas. The Gala Dinner was a great chance to unwind, catch up with friends and celebrate successes in the impressive surrounding of Melbourne Town Hall (pictured); the infamous organ played particularly rousing rendition of Phantom of the Opera on arrival.
The enthusiasm to strive for improvement is similar both home and away and therefore collaboration both nationally and internationally is integral for the progress of urology. The opening address by USANZ President included the phrase ‘together we can do so much more’ and this theme of collaboration was apparent throughout the conference. The future is bright with initiatives led by enthusiastic trainee groups BURST and YURO to collect large volume, high quality data from multiple centres, such as MIMIC which was presented by Dr Todd Manning. Social media, telecommunications and innovative technology should be used to further the specialty, especially with research and in cases of rare diseases – such as RPF. Twitter is a tool that can be harnessed and was certainly used freely with the hashtag #USANZ18. Furthermore, utilisation of educational learning platforms such as BJUI knowledge and evidence based guidelines help to facilitate high quality Urological practice regardless of state or country.
So we’d like to extend a huge thank you to Declan, Nathan and the whole team, and congratulate them for a successful, educational and friendly conference; all connections made will I’m sure last a lifetime and enable us to do more together.
