OBJECTIVE

To determine whether neoadjuvant chemotherapy (NAC) is a predictor of postoperative complications, length of stay (LOS), or operating time after radical cystectomy (RC) for bladder cancer.

PATIENTS AND METHODS

A retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was performed to identify patients receiving NAC before RC from 2005 to 2011. Bivariable and multivariable analyses were used to determine whether NAC was associated with 30-day perioperative outcomes, e.g. complications, LOS, and operating time.

RESULTS

Of the 878 patients who underwent RC for bladder cancer in our study, 78 (8.9%) received NAC. Excluding those patients who were ineligible for NAC due to renal insufficiency, 78/642 (12.1%) received NAC. In all, 457 of the 878 patients (52.1%) undergoing RC had at least one complication ≤30 days of RC, including 43 of 78 patients (55.1%) who received NAC and 414 of 800 patients (51.8%) who did not (P = 0.58). On multivariable logistic regression, NAC was not a predictor of complications (P = 0.87), re-operation (P = 0.16), wound infection (P = 0.32), or wound dehiscence (P = 0.32). Using multiple linear regression, NAC was not a predictor of increased operating time (P = 0.24), and patients undergoing NAC had a decreased LOS (P = 0.02).

CONCLUSIONS

Our study is the first large multi-institutional analysis specifically comparing complications after RC with and without NAC. Using a nationally validated, prospectively maintained database specifically designed to measure perioperative outcomes, we found no increase in perioperative complications or surgical morbidity with NAC. Considering these findings and the well-established overall survival benefit over surgery alone, efforts are needed to improve the uptake of NAC.

OBJECTIVE

To compare the early peri-operative, oncological and continence outcomes of Retzius-sparing robot-assisted laparoscopic radical prostatectomy (RALP) with those of conventional RALP.

MATERIALS AND METHODS

Data from 50 patients who underwent Retzius-sparing RALP and who had at least 6 months of follow-up were prospectively collected and compared with a database of patients who underwent conventional RALP. Propensity-score matching was performed using seven preoperative variables, and postoperative variables were compared between the groups.

RESULTS

A total of 581 patients who had undergone RALP were evaluated in the present study. Although preoperative characteristics were different before propensity-score matching, these differences were resolved after matching. There were no significant differences in mean length of hospital stay, estimated blood loss, intra- and postoperative complication rates, pathological stage of disease, Gleason scores, tumour volumes and positive surgical margins between the conventional RALP and Retzius-sparing RALP groups. Console time was shorter for Retzius-sparing RALP. Recovery of early continence (defined as 0 pads used) at 4 weeks after RALP was significantly better in the Retzius-sparing RALP group than in the conventional RALP group.

CONCLUSIONS

The present results suggest that Retzius-sparing RALP, although technically more demanding, was as feasible and effective as conventional RALP, and also led to a shorter operating time and faster recovery of early continence. Retzius-sparing RALP was also reproducible and achievable in all cases.

OBJECTIVE

To quantify changes in surgical practice in the treatment of stress urinary incontinence (SUI), urge urinary incontinence (UUI) and post-prostatectomy stress incontinence (PPI) in England, using the Hospital Episode Statistics (HES) database.

PATIENTS AND METHODS

We used public domain information from the HES database, an administrative dataset recording all hospital admissions and procedures in England, to find evidence of change in the use of various surgical procedures for urinary incontinence from 2000 to 2012.

RESULTS

For the treatment of SUI, a general increase in the use of synthetic mid-urethral tapes, such as tension-free vaginal tape (TVTO) and transobturator tape (TOT), was observed, while there was a significant decrease in colposuspension procedures over the same period. The number of procedures to remove TVT and TOT has also increased in recent years. In the treatment of overactive bladder and UUI, there has been a significant increase in the use of botulinum toxin A and neuromodulation in recent years. This coincided with a steady decline in the recorded use of clam ileocystoplasty. A steady increase was observed in the insertion of artificial urinary sphincter (AUS) devices in men, related to PPI.

CONCLUSIONS

Mid-urethral synthetic tapes now represent the mainstream treatment of SUI in women, but tape-related complications have led to an increase in procedures to remove these devices. The uptake of botulinum toxin A and sacral neuromodulation has led to fewer clam ileocystoplasty procedures being performed. The steady increase in insertions of AUSs in men is unsurprising and reflects the widespread uptake of radical prostatectomy in recent years. There are limitations to results sourced from the HES database, with potential inaccuracy of coding; however, these data support the trends observed by experts in this field.

OBJECTIVE

To describe a step-by-step guide for successful implementation of the retroperitoneal approach to robotic partial nephrectomy (RPN)

PATIENTS AND METHODS

The patient is placed in the flank position and the table fully flexed to increase the space between the 12th rib and iliac crest. Access to the retroperitoneal space is obtained using a balloon-dilating device. Ports include a 12-mm camera port, two 8-mm robotic ports and a 12-mm assistant port placed in the anterior axillary line cephalad to the anterior superior iliac spine, and 7–8 cm caudal to the ipsilateral robotic port.

RESULTS

Positioning and port placement strategies for successful technique include: (i) Docking robot directly over the patient’s head parallel to the spine; (ii) incision for camera port ≈1.9 cm (1 fingerbreadth) above the iliac crest, lateral to the triangle of Petit; (iii) Seldinger technique insertion of kidney-shaped balloon dilator into retroperitoneal space; (iv) Maximising distance between all ports; (v) Ensuring camera arm is placed in the outer part of the ‘sweet spot’.

CONCLUSION

The retroperitoneal approach to RPN permits direct access to the renal hilum, no need for bowel mobilisation and excellent visualisation of posteriorly located tumours.

OBJECTIVE

• To compare overall and cancer-specific outcomes between patients with upper tract urothelial carcinoma (UTUC) managed with either radical nephroureterectomy (RNU) or nephron-sparing measures (NSM) using a large population-based dataset.

PATIENTS AND METHODS

• Using Surveillance, Epidemiology, and End Results (SEER) data, patients diagnosed with low- or moderate-grade, localised non-invasive UTUC were stratified into two groups: those treated with RNU or NSM (observation, endoscopic ablation, or segmental ureterectomy).

• Cancer-specific mortality (CSM) and other-cause mortality (OCM) rates were determined using cumulative incidence estimators. Adjusting for clinical and pathological characteristics, the associations between surgical type, all-cause mortality and CSM were tested using Cox regressions and Fine and Gray regressions, respectively.

RESULTS

• Of 1227 patients [mean (sd) age 70.2 (11.00) years, 63.2% male] meeting inclusion criteria, 907 (73.9%) and 320 (26.1%) patients underwent RNU and NSM for low- or moderate-grade, low-stage UTUC from 1992 to 2008.

• Patients undergoing NSM were older (mean age 71.6 vs 69.7 years, P < 0.01) with a greater proportion of well-differentiated tumours (26.3% vs 18.0%, P = 0.001).

• While there were differences in OCM between the groups (P < 0.01), CSM trends were equivalent. After adjustment, RNU treatment was associated with improved non-cancer cause survival [hazard ratio (HR) 0.78, confidence interval [CI] 0.64–0.94) while no association with CSM was demonstrable (HR 0.89, CI 0.63–1.26).

CONCLUSIONS

• Patients with low- or moderate-grade, low-stage UTUC managed through NSM are older and are more likely to die of other causes, but they have similar CSM rates to those patients managed with RNU.

• These data may be useful when counselling patients with UTUC with significant competing comorbidities.

OBJECTIVE

• To address the biochemical and functional outcomes after radical prostatectomy (RP) of men aged <50 years in a large European population.

PATIENTS AND METHODS

• Among 13 268 patients who underwent RP for clinically localised prostate cancer at our centre (1992–2011), 443 (3.3%) men aged <50 were identified.

• Biochemical recurrence (BCR) and functional outcomes (International Index of Erectile Function [IIEF-5], use of pads), were prospectively evaluated and compared between men aged <50 years and older patients.

RESULTS

• Men aged <50 years were more likely to harbour D’Amico low-risk (49.4 vs 34.9%, P < 0.001), organ-confined (82.6 vs 69.4%, P < 0.001) and low-grade tumours (Gleason score <7: 33.1 vs 28.7%, P < 0.001).

• Multivariate Cox regression analysis showed that age <50 years (hazard ratio 0.99; confidence interval 0.72–1.31; P = 0.9) was not a predictor of BCR.

• Urinary continence was more favourable in younger patients, resulting in continence rates of 97.4% vs 91.6% in most recent years (2009–2011) for patients aged <50 vs ≥50 years.

• After RP, a median IIEF-5 drop of 4 points in younger men vs 8 points in older patients was recorded (P < 0.001).

• Favourable recovery of urinary continence and erectile function in patients aged <50 years compared with their older counterparts was confirmed after multivariable adjustment.

CONCLUSION

• Men aged <50 years diagnosed with localised prostate cancer should not be discouraged from RP, as the postoperative rates of urinary incontinence and erectile dysfunction are low and probability of BCR-free survival at 2 and 5 years is high.

OBJECTIVE

To examine the association of hospital volume and 90-day mortality after cystectomy, conditional on survival for 30 days.

PATIENTS AND METHODS

The National Cancer Data Base was used to evaluate 30- and 90-day mortality for 35 055 patients who underwent cystectomy for bladder cancer at one of 1118 hospitals.

Patient data were aggregated into hospital volume categories based on the mean annual number of procedures (low-volume hospital: <10 procedures; intermediate-volume hospital: 10–19 procedures; high-volume hospital: ≥20 procedures).

Associations between mortality and clinical, demographic and hospital characteristics were analysed using hierarchical logistic regression models. To assess the association between hospital volume and 90-day mortality independently of shorter-term mortality, 90-day mortality conditional on 30-day survival was assessed in the multivariate modelling.

RESULTS

Unadjusted 30- and 90-day mortality rates were 2.7 and 7.2% overall, 1.9 and 5.7% among high-volume hospitals, and 3.2 and 8.0% among low-volume hospitals, respectively.

Compared with high-volume hospitals, the adjusted risks among low-volume hospitals (odds ratio [95% CI]) of 30- and 90-day mortality, conditional on having survived for 30 days, from the hierarchical models were 1.5 (1.3–1.9), and 1.2 (1.0–1.4), respectively.

CONCLUSIONS

A low hospital volume was associated with greater 30- and 90-day mortality. These data support the need for further research to better understand the relatively high mortality rates seen between 30 and 90 days, which are high and less variable across hospital volume strata.

The stronger association between volume and 30-day mortality suggests that quality-reporting efforts should focus on shorter-term outcomes.

OBJECTIVE

• To examine the effect of penile vibratory stimulation (PVS) in the preservation and restoration of erectile function and urinary continence in conjunction with nerve-sparing radical prostatectomy (RP).

PATIENTS AND METHODS

• The present study was conducted between July 2010 and March 2013 as a randomized prospective trial at two university hospitals. Eligible participants were continent men with an International Index of Erectile Function-5 (IIEF-5) score of at least 18, scheduled to undergo nerve-sparing RP.

• Patients were randomized to a PVS group or a control group. Patients in the PVS group were instructed in using a PVS device (FERTI CARE® vibrator).

• Stimulation was performed at the frenulum once daily by the patients in their own homes for at least 1 week before surgery. After catheter removal, daily PVS was re-initiated for a period of 6 weeks.

• Participants were evaluated at 3, 6 and 12 months after surgery with the IIEF-5 questionnaire and questions regarding urinary bother. Patients using up to one pad daily for security reasons only were considered continent. The study was registered at https://clinicaltrials.gov/ (NCT01067261).

RESULTS

• Data from 68 patients were available for analyses (30 patients randomized to PVS and 38 patients randomized to the control group).

• The IIEF-5 score was highest in the PVS group at all time points after surgery with a median score of 18 vs 7.5 in the control group at 12 months (P = 0.09), but the difference only reached borderline significance.

• At 12 months, 16/30 (53%) patients in the PVS group had reached an IIEF-5 score of at least 18, while this was the case for 12/38 (32%) patients in the control group (P = 0.07).

• There were no significant differences in the proportions of continent patients between groups at 3, 6 or 12 months. At 12 months 90% of the PVS patients were continent, while 94.7% of the control patients were continent (P = 0.46).

CONCLUSION

• The present study did not document a significant effect of PVS. However, the method proved to be acceptable for most patients and there was a trend towards better erectile function with PVS. More studies are needed to explore this possible effect further.

OBJECTIVE

• To evaluate the safety and efficacy of epidermal growth factor receptor (EGFR)-targeted therapy in patients with advanced penile or scrotal cancer.

PATIENTS AND METHODS

• We retrospectively reviewed the charts of patients with penile or scrotal squamous cell carcinoma who had visited our tertiary cancer centre between 2002 and 2009, including their subsequent treatment and follow-up.

• We collected details of EGFR-targeted therapy and clinical outcomes. Treatment-associated time-to-disease-progression (TTP), overall survival (OS), responses to therapy and toxicity were evaluate

RESULTS

• A total of 24 patients had received EGFR-targeted therapies, including cetuximab, erlotinib and gefitinib. The most common treatment given (to 67% of patients) was cetuximab combined with one or more cytotoxic drugs.

• The most common adverse effect was skin rash (71%). The median (range) TTP and OS were 11.3 (1–40) and 29.6 (2–205) weeks, respectively. The OS time for patients with visceral or bone metastases was significantly shorter than it was for those without (24.7 vs 49.9 weeks, P = 0.013).

• Among 17 patients treated with cetuximab alone or in combination with cisplatin, there were four partial responses (23.5%) including two patients with apparently chemotherapy-resistant tumours.

CONCLUSIONS

• Our results suggest that cetuximab has antitumour activity in metastatic penile cancer, and may enhance the effect of cisplatin-based chemotherapy.

• Prospective studies of EGFR-targeted therapies in men with these tumours are warranted

The Big Data challenge: amplify your content using video and maximise your impact

/3 Comments/by

It remains a great achievement for an author to have his or her work published in a peer-reviewed journal such as the BJUI. There is a tremendous sense of fulfilment when the e-mail from the Editor-in-Chief includes ‘accept’ in the subject heading. What may have been a long period from study design, through ethics approval, patient recruitment, intervention, data collection, statistical analysis, manuscript preparation, to final revisions, finally comes to an end – chapter closed, move on.

However, in this era of ‘Big Data’, we are now confronted with new challenges with respect to getting our content noticed. It is estimated that of all the data created in the history of mankind, from early cave drawings to medieval manuscripts and modern web 2.0 communication, >90% has been created in the past 2 years alone [1]. Two thousand years ago, 90% of the world’s content was thought to be archived in just one place, the Library of Alexandria in Egypt, and all of that content would easily fit on a flash drive today. With this massive amount of new data emerging, the current challenge is not just to get published, but also to get your work noticed. Are you always looking out for new methods of approaching potential customers? If the answer is yes, then you should definitely try out a geocoding service. Just imagine, you will have a large map in front of you, where the locations of all your customers are marked. You will know exactly where your customers live, and in which regions your products and services are most popular. Just think of what you can do with this knowledge. For starters, how about running some location based targeted marketing campaigns? These campaigns are sure to bring in lots of new customers, if you can fine-tune these properly. Geoparsing API by Geocodeapi.io can be done simply through address interpolation, which uses data from a street GIS where the street network is already inputted within the geographic coordinate space. Attributed in each street segment are address ranges, such as house numbers from one segment to another. Here is what geocoding does: (1) It takes an address, (2) matches it to a street and particular segment (e.g. a block), and (3) interpolates the address position. However, issues may arise in the geocoding process. What happens is that you have to distinguish between ambiguous addresses (say, “43 Hampton Drive” and “43E Hampton Drive”). It’s also a challenge when you geocode new addresses for a street that is not yet added to the GIS database. Using interpolation also entails a number of caveats, including the fact that it assumes that the parcels are evenly spaced along the length of the segment. This is quite unlikely in reality – it can be that a geocode address is off by a number of thousand feet. A more sophisticated geocoding application will match geocode information to the property level, using such tools as USPS address data, and cascade out to block, track or other levels depending on data matching accuracy.

This is where social media can help your content to rise above the morass and get into the mind of your target audience. At the BJUI, we have integrated social media into every aspect of the Journal [2], as it is clear that this is important for our readers [3]. The use of popular platforms, e.g. Twitter, YouTube, Facebook and Instagram, as well as our own blog site, allows us to greatly amplify the reach of our content, at lightning speed, and allows us to engage with our readers in a way that traditional print publishing never could.

In the video accompanying this editorial, we offer some practical advice to help our authors create high-quality video to augment their content. This advice includes:

  • Capture at the highest quality possible – digital video recorders outperform DVDs and are essential for laparoscopic and robotic work. For open surgery, a GoPro is our preferred capture device but an iPhone can also provide good footage.
  • Editing brings the video to life: video editing software is widely available and can transform your video from a dull procession into a vivid story. Add in additional footage (e.g. operating room footage to go with your laparoscopic video), still pictures, graphs, imaging etc, and add titles to help illustrate your key messages.
  • Output for social – your video-editing software will allow you to export your movie in a format optimised for YouTube (e.g. FLV file), or to upload directly to YouTube. Or just export it in a high-quality format and we will upload to YouTube for you.

We encourage the use of video to accompany any type of publication at BJUI, including web-only content such as blogs, and we require it for featured content such as the ‘Article of the Week’, ‘Article of the Month and Step by Step articles’. Videos in a surgical specialty like urology are often focused on procedural technique, but they do not have to be this limited and we encourage all other types of BJUI content to also be supplemented with video. Our BJUI Tube site and YouTube site contain good examples of how authors can describe their content with video by using figures and tables in an interview-style format. This latest video addresses issues around the capture and editing of videos to optimally complement your published work. These videos are then disseminated to a wider audience through our large social media network. All of our videos are ≈3 min in duration, as our analytics demonstrate that viewers ‘switch off’ when videos run for much longer.

We therefore encourage you to think social, think video, and help your content reach its maximum audience. We are here to help you!
