Routine urethroscopic surveillance is of limited value after radical cystectomy: a single centre retrospective cohort analysis.

PURPOSE: The incidence of urethral recurrence (UR) following radical cystectomy (RC) for transitional cell carcinoma (TCC) of the bladder varies between 1.5 and 6%. There is debate over the timing of urethrectomy for patients undergoing RC. We evaluated the requirement for a formal surveillance programme for UR in patients after RC. METHODS: We retrospectively reviewed the outcomes of patients who underwent RC between 2006 and 2019. Females, non-TCC cases and patients with neo-bladder diversions were excluded. Histological prostatic urethral involvement at the time of RC was deemed high risk for UR. Carcinoma in-situ, multifocal tumours and bladder neck involvement were deemed intermediate risk and the absence of the above features was considered low risk. RESULTS: 417 patients underwent RC, 300 cases remained after exclusion criteria were applied. 42 patients were high-risk for UR, 102 patients were intermediate risk and 156 were low risk. Of the 300, 24 urethrectomy cases were recorded. Six cases of UR occurred. Of these, 5 presented with symptoms and only 1 case was detected by surveillance. Only 1 low-risk patient developed UR, 7 years post RC. Using our risk stratification, UR rates for high, intermediate and low-risk cohorts were 25%, 10.5% and 0.8%, respectively. CONCLUSIONS: In our cohort, routine surveillance for all patients with annual urethroscopy was of limited value in detecting UR post RC. Staged Urethrectomy for high and intermediate-risk patients, and patient counselling in self-identification of recurrence symptoms for low-risk patients will improve the early detection of UR.

Changes in UK renal oncological surgical practice from 2008 to 2017: implications for cancer service provision and surgical training.

OBJECTIVE: To determine and analyse the temporal changes in oncological nephrectomy practice and training opportunities using data obtained from the UK British Association of Urological Surgeons nephrectomy register from 2008 to 2017. PATIENT AND METHODS: All nephrectomies within the dataset for this time period were analysed (n = 54 251). Cases were divided into radical nephrectomy (RN), partial nephrectomy (PN) and nephroureterectomy (NU). Simple nephrectomy, donor nephrectomy and benign PN were excluded. The annual frequencies for each oncological nephrectomy method, surgical approach, grade of surgeon, hospital caseload numbers and short-term surgical outcomes were determined. RESULTS: Reported annual nephrectomy numbers increased by 2.5-fold in the 9-year time period. The number of hospitals performing nephrectomies decreased by 22%, however, more than 40% of centres performed more than 70 cases a year. There was a trend towards a decrease in overall length of hospital stay (9 vs 5 days; P < 0.01) and decreased transfusion rates. The proportion of minimally invasive procedures increased from 57% to 75%, with nephron-sparing rates increasing from 8.9% overall to 24.8%. With regard to surgical technique, robot-assisted surgery saw a mean annual increase of 222%. Overall, there was a 10% decrease in the proportion of PNs performed by trainee surgeons. CONCLUSIONS: Renal surgery has changed considerably with regard to volume and also surgical approach, with rates of nephron-sparing surgery and minimally invasive surgery significantly increasing. Increasing hospital centralization and institutional experience, and a shift to robot-assisted surgery appear to have contributed to the observed improved patient outcomes. The increasing utilization of robot-assisted surgery has potential implications and challenges for the training of future urology surgeons.

Benign prostatic hyperplasia - what do we know?

OBJECTIVES: To present historical and contemporary hypotheses on the pathogenesis of benign prostatic hyperplasia (BPH), and the potential implications for current medical therapies. METHODS: The literature on BPH was reviewed. BPH is a prevalent disease with significant health and economic impacts on patients and health organisations across the world, whilst the cause/initiation of the disease process has still not been fully determined. RESULTS: In BPH, pathways involving androgens, oestrogens, insulin, inflammation, proliferative reawakening, stem cells and telomerase have been hypothesised in the pathogenesis of the disease. A number of pathways first described >40 years ago have been first rebuked and then have come back into favour. A system of an inflammatory process within the prostate, which leads to growth factor production, stem cell activation, and cellular proliferation encompassing a number of pathways, is currently in vogue. This review also highlights the physiology of the prostate cell subpopulations and how this may account for the delay/failure in treatment response for certain medical therapies. CONCLUSION: BPH is an important disease, and as the pathogenesis is not fully understood it impacts the effectiveness of medical therapies. This impacts patients, with further research potentially highlighting novel therapeutic avenues.

Renal vein leiomyosarcoma and renal cell carcinoma presenting together: A case report and discussion on the follow-up.

Leiomyosarcoma affecting the renal vein is rare, with about 30 documented cases in the English literature. The appearance on computed tomography can be difficult to interpret and is often confused with advanced renal cell carcinoma (RCC). This confusion can have implications on the perioperative care of patients presenting with this disease. We report a case with an usual radiological appearance of a renal vein leiomyosarcoma, alongside a separate RCC. This case highlights the need for a high index of suspicion in radiological reporting and provides a dilemma in regards to postoperative surveillance.
