Introduction: The gold standard treatment for high risk upper tract urothelial cancers is radical nephroureterectomy. Little evidence exists specifically directed for octogenarians with this disease, therefore we highlight our centre’s outcomes and compare to current literature. Methods: Demographic, operative and postoperative data were collected on all octogenarian patients who underwent minimally invasive radical nephroureterectomy between 2010 and 2018 in a single centre. Outcomes including intraoperative and postoperative complications, disease recurrence rates and survival data were analysed. A literature search was performed, with six included articles of cases series and retrospective cohort studies after screening of full manuscripts. Results: Twenty-three patients of average age 82.6 years (range 80–85) were included. Length of stay was median 10 days (range 5–53). Six patients (25%) had postoperative complications ranging from Clavien–Dindo classification 2–3. Eight patients were found to have recurrence, with median time to recurrence of 18 months. Of the 13 patients who died during a follow-up of median 38.4 months, five patients (22%) died of disease related to their original diagnosis (median survival 20 months). Conclusions: From this single centre case series results combined with a review of current literature, radical nephroureterectomy is safe for octogenarian patients for upper tract urothelial cancers when appropriately selected. Further work will need to be carried out to assess the role of lymphadenectomy and adjuvant chemotherapy in the older patient cohort. Level of evidence Level 4

Aim: This was a retrospective cohort study exploring the efficacy of mini-percutaneous nephrolithotomy in obese patients and whether stone clearance, complication rate and length of stay is impacted by an increasing body mass index. Method: Data was collected retrospectively for all mini-percutaneous nephrolithotomies performed at a single centre over a 21-month period commencing March 2017. The primary outcomes included length of stay, stone clearance rates and complications. Results: Fifty-eight percutaneous nephrolithotomies were undertaken during the study period and of these cases 81% of patients had a body mass index of 25 or greater. The stone clearance rate was 83%. However, severely obese patients were noted to have a lower stone clearance rate. No complications occurred in the normal body mass index cohort. However, there was no difference in the complication rate for the remaining groups. Post-operative stay was approximately 3 days. Conclusion: This study demonstrates that supine mini-percutaneous nephrolithotomies are a safe option in obese patients with no increased risk of serious complication. Whilst stone clearance rates were lower in the severely obese category, clearance was complete in the majority of cases. Level of evidence: 3

Objective: Circumcision is a commonly performed urological procedure, histology is often requested with unexpected malignancy cited as the reason. This paper aims to determine if routine histology following circumcision alters the clinical management of patients. Patients and methods: The clinical records of 508 consecutive adult patients circumcised at a district general hospital between 1/1/12 and 31/12/16 were retrospectively reviewed. Two groups were available for comparison, those with histological diagnosis (359 patients) and those with a clinical diagnosis only (149 patients). The following data were collected: indication for circumcision; preoperative clinical and histological diagnosis; patient follow-up (mean 40 months). Results: A total of 508 patients were reviewed. Histology was requested for 359 specimens (70.7%). Six cases of squamous cell carcinoma were correctly identified clinically and there were no cases of unexpected malignancy. The clinical diagnosis of lichen sclerosus was correct in 92% of cases; 39 patients were re-referred following discharge, only one required further management of a urethral stricture. Conclusion: The results of our study show there is no difference in the outcomes or re-referral rates of patients who have routine histology requested following circumcision compared with those who do not. Clinical diagnosis is consistently accurate. There is a minimal number of patients referred back to the service, even with lichen sclerosus, and histology does not affect the rate of this. We conclude that routine histology does not alter patient management following circumcision and is not required unless a clinical suspicion of malignancy exists. This study represents the largest cohort of circumcision patients and includes the longest period of follow-up to add to the current body of literature. Levels of evidence: 2b retrospective consecutive cohort study with follow up.

Aims Percutaneous nephrolithotomy is known to have a significant risk of sepsis and traditionally the systemic inflammatory response score has been used to identify post-operative patients requiring higher levels of care. Recently, the quick Sepsis Related Organ Failure Assessment score has been developed as a rapid and easy tool to assess patients likely to deteriorate from sepsis. We aim to evaluate the quick Sepsis Related Organ Failure Assessment system against the established systemic inflammatory response score criteria in identifying patients at risk of intensive care unit admission following percutaneous nephrolithotomy. Patients and Methods A retrospective review of 157 patients undergoing percutaneous nephrolithotomy between May 2015 and November 2018 at our institution was performed. Patient demographics of age, sex and American Society of Anesthesiologists’ score were collected. Quick Sepsis Related Organ Failure Assessment and systemic inflammatory response scores were calculated at 24 hours and 7 days post-operatively. Primary outcome was admission to an intensive care unit. Specificity, sensitivity, positive and negative predictive values were calculated for the systemic inflammatory response and quick Sepsis Related Organ Failure Assessment scores. Results Of 157 patients undergoing percutaneous nephrolithotomy, eight (5.1%) and 52 (33.1%) scored positively for quick Sepsis Related Organ Failure Assessment and systemic inflammatory response score criteria within 24 hours. Quick Sepsis Related Organ Failure Assessment scoring had a higher specificity (98.7%: 95% confidence interval 98.6–98.7%) and positive predictive value (75.0: 95% confidence interval 74.0–75.0%) than systemic inflammatory response score criteria (69.5%: 95% confidence interval 69.3–69.7%), (11.5%; 95% confidence interval 1.2–11.8%) in predicting intensive care unit admission following percutaneous nephrolithotomy. Quick Sepsis Related Organ Failure Assessment correlated strongly with intensive care unit admission and overall length of stay, whereas systemic inflammatory response score correlated weakly with both parameters. Conclusion Quick Sepsis Related Organ Failure Assessment demonstrated a statistically significant improvement in predicting intensive care unit admission and overall length of stay versus systemic inflammatory response score criteria following percutaneous nephrolithotomy. Further multi-centre studies are required to validate these findings, which are the first to be published in a urology-specific patient population. Level of Evidence: 4

Background: Post-vasectomy semen analysis timing and criteria guidelines have evolved over time. Through analysis of our unit’s practice of post-vasectomy semen analysis from earlier sampling protocols at 8 weeks to single sampling at 12 weeks then 16 weeks, the impact on success rates and patient compliance were assessed. In addition, the use of small numbers of non-motile sperm and azoospermia combined rates as a marker of sterility were examined. Methods: All patients who underwent vasectomy in 2011 (8 and 12-week samples), 2013 (12-week samples) and 2016 (16-week samples) were included. Patients were given written and verbal instructions explaining the sample delivery protocol and samples. χ2 Testing was used to compare patient compliance and the results of post-vasectomy semen analysis with significance set at PResults: In total 1124 vasectomies were performed, with 21% ( N=232) of patients non-compliant with submitting samples at the requested time period. Azoospermia rates increased with a longer time to post-vasectomy semen analysis from 82% to 95%, PConclusion: The use of earlier post-vasectomy semen analysis is recommended as patient compliance decreases with the time from vasectomy. When azoospermia and small non-motile sperm rates are combined the rates of success of the procedure remain the same over time therefore earlier testing at 8 weeks is feasible without compromising clearance rates.

Background: Penile cancer is a rare disease, with approximately 600 cases diagnosed every year in the UK. In this study, we assessed the impact of social deprivation on penile cancer, concentrating on incidence, disease factors, surgical treatment and mortality within our ‘Supranetwork’ population. Methods: All cases of penile cancer in the West of Scotland were identified from the uro-oncology multidisciplinary team meetings over a 10-year period covering January 2008 to December 2017. Patients underwent treatment within the remit of a centralised service, and social deprivation was determined using the Scottish Index of Multiple Deprivation (SIMD), which is the Scottish government’s official tool to identify areas of multiple deprivations. Results: A total of 278 patients were identified, with an age range of 27–97 years ( M=64 years). The incidence of penile cancer in SIMD category 1 (most deprived) is 7.2/100,000 population at risk compared to 2.8/100,000 population at risk in SIMD category 5 (least deprived). Histologically, a higher proportion of aggressive grade 3 cancers (45% vs. 16%, p=0.03) and more advanced N2/N3 nodal disease (63% vs. 33%, p=0.04) was found in SIMD category 1 compared to SIMD category 5, suggesting higher incidence of delayed presentation with more advanced and aggressive disease in the most deprived populations. Conclusions: The level of social deprivation shows a significant association with penile cancer incidence, tumour grade and stage at time of diagnosis, with a resulting disproportionate impact on morbidity and mortality in the most deprived cohort of patients. Public awareness and efforts to increase earlier diagnoses of penile cancer in these ‘hard to reach’ men should be an important step in improving overall outcomes from penile cancer.
