RSM Urology Winter Meeting 2017, Northstar, California

rsm-2017-blogThis year’s Annual RSM Urology Section Winter Meeting, hosted by Roger Kirby and Matt Bultitude, was held in Lake Tahoe, California.

A pre-conference trip to sunny Los Angeles provided a warm-up to the meeting for a group of delegates who flew out early to visit Professor Indy Gill at the Keck School of Medicine.  We were treated to a diverse range of live open, endourological and robotic surgery; highlights included a salvage RARP with extended lymph node dissection and a robotic simple prostatectomy which was presented as an alternative option for units with a robot but no/limited HoLEP expertise.

On arrival to Northstar, Dr Stacy Loeb (NYU) officially opened the meeting by reviewing the social media urology highlights from 2016. Next up was Professor Joseph Smith (Nashville) who gave us a fascinating insight into the last 100 years of urology as seen through the Journal of Urology. Much like today, prostate cancer and BPH were areas of significant interest although, in contrast, early papers focused heavily on venereal disease, TB and the development of cystoscopy. Perhaps most interesting was a slightly hair-raising description of the management of IVC bleeding from 1927; the operating surgeon was advised to clamp as much tissue as possible, close and then return to theatre a week later in the hopes the bleeding had ceased!

With the promise of beautifully groomed pistes and stunning views of Lake Tahoe, it was hardly surprising that the meeting was attended by a record number of trainees. One of the highlights of the trainee session was the hilarious balloon debate which saw participants trying to convince the audience of how best to manage BPH in the newly inaugurated President Trump. Although strong arguments were put forward for finasteride, sildenafil, Urolift, PVP and HoLEP, TURP ultimately won the debate. A disclaimer: this was a fictional scenario and, to the best of my knowledge, Donald Trump does not have BPH.

The meeting also provided updates on prostate, renal and bladder cancer. A standout highlight was Professor Nick James’ presentation on STAMPEDE which summarized the trial’s key results and gave us a taste of the upcoming data we can expect to see in the next few years.

We were fortunate to be joined by prominent American faculty including Dr Trinity Bivalacqua (Johns Hopkins) and Dr Matt Cooperberg (UCSF) who provided state-of-the-art lectures on potential therapeutic targets and biomarkers in bladder and prostate cancer which promise to usher in a new era of personalized therapy.

A personal highlight was Tuesday’s session on learning from complications. It was great to hear some very senior and experienced surgeons speaking candidly about their worst complications. As a trainee, it served as a reminder that complications are inevitable in surgery and that it is not their absence which distinguishes a good surgeon but rather the ability to manage them well.

There was also plenty for those interested in benign disease, including topical discussions on how to best provide care to an increasingly ageing population with multiple co-morbidities. This was followed by some lively point-counterpoint sessions on robot-assisted versus open renal transplantation (Ravi Barod and Tim O’Brien), Urolift vs TURP (Tom McNicholas and Matt Bultitude) and HOLEP vs prostate artery embolization for BPH (Ben Challacombe and Rick Popert). Professor Culley Carson (University of North Carolina) concluded the session with a state-of-the art lecture on testosterone replacement.

In addition to the excellent academic programme, delegates enjoyed fantastic skiing with perfect weather and unparalleled views of the Sierra Nevada Mountains. For the more adventurous skiiers, there was also a trip to Squaw Valley, the home of the 1960 Winter Olympics. Another highlight was a Western-themed dinner on the shores of Lake Tahoe which culminated in almost all delegates trying their hand at line dancing to varying degrees of success! I have no doubt that next year’s meeting in Corvara, Italy will be equally successful and would especially encourage trainees to attend what promises to be another excellent week of skiing and urological education.

Objective

To determine the scope and outcomes of nephron-sparing surgery (NSS), i.e. partial nephrectomy, across the UK and in so doing set a realistic benchmark and identify fresh contemporary challenges in NSS.

Patients and Methods

In 2012 reporting of outcomes of all types of nephrectomy became mandatory in the UK. In all, 148 surgeons in 86 centres prospectively entered data on 6 042 nephrectomies undertaken in 2012. This study is a retrospective analysis of the NSS procedures in the dataset.

Results

A total of 1 044 NSS procedures were recorded and the median (range) surgical volume was 4 (1–39) per consultant and 8 (1–59) per centre. In all, 36 surgeons and 10 centres reported on only one NSS. The indications for NSS were: elective with a tumour of ≤4.5 cm in 59%, elective with a tumour of >4.5 cm in 10%, relative in 7%, imperative in 12%, Von Hippel–Lindau in 1%, and unknown in 11%. The median (range) tumour size was 3.4 (0.8–30) cm. The technique used was minimally invasive surgery in 42%, open in 58%, with conversions in 4%. The histology results were: malignant in 80%, benign in 18%, and unknown in 2%. In patients aged <40 years 36% (36/101) had benign histology vs 17% (151/874) of those aged ≥40 years (P < 0.01). In patients with tumours of <2.5 cm 29% (69/238) had benign histology vs 14% (57/410) with tumours of 2.5–4 cm vs 8% (16/194) with tumours of ≥4 cm (P = 0.02). In patients aged <40 years with of tumours of <2.5 cm 44% (15/34) were benign. The 30-day mortality was 0.1% (1/1 044). There were major complications (Clavien–Dindo grade of ≥IIIa) in 5% (53/1 044). There was an increased risk of complications after extended elective NSS of 19% (19/101) vs elective at 12% (76/621) (relative risk [RR] 1.54; P < 0.01). Margins were recorded in 68% (709/1 044) of the patients, with positive margins identified in 7% (51/709). Positive surgical margins after NSS for pathological T3 (pT3) tumours were found in 47.8% (11/23) vs 6.1% (32/523) for pT1a, tumours (RR 5.61; P < 0.01). In all, 14% (894/6 042) of the patients underwent surgery for T1a tumours: 55% (488/894) by NSS, 42% (377/894) by radical nephrectomy (RN), and in 3% (29/894) the procedure used was unknown. Major complications after occurred in 4.9% (24/488) of NSS vs 1.3% (5/377) of RN (P < 0.01). Limitations included poor reporting of renal function data and no data on tumour complexity.

Conclusions

In its first year, mandatory national reporting has provided several challenging contemporary insights into NSS.

Editorial: SRMs – Where is the Wisdom We Have Lost in Knowledge?

The perceived wisdom that a small enhancing mass in the kidney represents a surgical lesion that automatically requires excision without the need for a preoperative biopsy has been challenged by Fernando et al. [1] in this issue of BJUI.

The authors are to be congratulated in bringing these data to publication to provoke debate on the treatment paradigm for small renal masses (SRMs) by reviewing nationally collected data on the main therapeutic surgical option: nephron-sparing surgery. As anyone who has attended a renal multidisciplinary meeting can testify, the predominant presentation of renal cancer is the incidentally detected SRM, often in elderly patients with significant comorbidity.

As the authors emphasize, these data are unique in representing a national picture encompassing both high- and low-volume centres, as opposed to the majority of the studies in the literature, which report data from high-volume tertiary referral centres.

Drawing conclusions from data requires a clear understanding of the source and quality. Most importantly, as these data only refer to patients undergoing nephron-sparing surgery, we need to be cautious about extrapolating to infer information on the management of SRMs in general.

For instance, a striking finding of the present study is the high incidence of benign lesions in the younger age groups. We have no knowledge of the numbers of patients with SRMs within the study period who had biopsy-proven benign disease and thus avoided surgery. It is probable that the true incidence of benign disease would be even higher if these cases had been recorded and included in the analysis.

An inherent difficulty with self-reported data is the issue of compliance, and this is clearly evident in the present study, with, for example, almost a third of cases missing data on surgical margin results. It would perhaps be helpful for future audits if the BAUS dataset had a clear definition of positive surgical margin in recognition of the surgical drift to enucleation rather than excision with a margin of renal parenchyma.

The variation in caseload between reporting centres raises important questions, as does the finding that two fifths of patients with T1a tumours underwent radical nephrectomies. As the authors concede, with the numbers involved and the absence of any measure of tumour complexity, it is difficult to draw firm conclusions; however, the study does highlight the need to examine this issue in future analyses and to consider including some form of renal scoring system in future audits.

Where do we go from here and what can we do with this information? First, we need to rethink our discussion with patients with SRMs. Can we justify performing major surgery with a one in 20 chance of a significant complication for a possible benign lesion without at least a pragmatic discussion of the role of renal biopsy with the patient? Indeed, one may argue, could it really be an ‘informed’ decision without it?

Second, we need to improve the quality of the data by encouraging robust data reporting, increasing the completion rate and considering adding data fields which will allow us to draw clearer conclusions on surgical margin and surgical outcome and volume relationships.

Third, we need to recognize that nephron-sparing surgery is only one component of the management of SRMs, which represents a major contemporary challenge in terms of health resources and, most importantly, in deciding the best treatment paradigm for our patients. If BAUS can carry out this audit, could we not extend this to all patients with SRMs, whether they have surgery, ablation or surveillance, and establish greater clarity on these treatment methods?
