Urinary symptoms and pain associated with indwelling ureteral stents interfere with daily activities and result in reduced quality of life in up to 80% of patients. Stents are associated with negative functional capacity and reduced utility values. The results have implications in terms of routine clinical practice, patient counseling and future stent research.

Indwelling ureteral stents have a significant impact on health related quality of life. The new USSQ is a valid and reliable instrument that is expected to become a standard outcome measure to evaluate the impact and compare different types of stents.

The majority of complications after PCNL are minor. Longer operative time and higher ASA scores are associated with the risk of more severe postoperative complications in PCNL.

OBJECTIVES To present the results of a minimally invasive treatment of symptomatic simple renal cysts, and to propose an algorithm for their management. PATIENTS AND METHODS Seventeen patients presenting with suspected symptomatic simple renal cysts were referred for trial aspiration; 16 presented with loin pain and one with a flank mass. If the cyst and symptoms recurred after a temporary response, they were managed by re‐aspiration with sclerotherapy using 95% ethanol, or by laparoscopic de‐roofing of the cyst. RESULTS Of the 17 patients referred, one failed to respond to aspiration and was excluded from further analysis. Three patients had sustained pain relief from simple aspiration alone, 13 required further treatment for symptom relapse, of whom six had aspiration and sclerotherapy, and seven had laparoscopic de‐roofing. After a mean follow‐up of 17 months, pain had recurred in all five patients originally presenting with pain and managed by sclerotherapy, and the patient who presented with a painless mass from a large cyst also developed pain after sclerotherapy. In contrast, the subsequent seven patients managed by laparoscopic treatment are pain‐free at a mean follow‐up of 17.7 months. CONCLUSION Evaluation including a diagnostic aspiration is essential to diagnose a symptomatic cyst. When treatment is indicated, laparoscopic de‐roofing appears to be more effective than sclerotherapy.

Indwelling ureteral stents are associated with significant morbidity, resulting in a reduced HRQoL in 80% of patients. The SSQ is a reliable intervention-specific instrument that would be useful as an outcome measure to evaluate the impact of stents.

SummaryBackgroundRepeated symptomatic urinary tract infections (UTIs) affect 25% of people who use clean intermittent self-catheterisation (CISC) to empty their bladder. We aimed to determine the benefits, harms, and cost-effectiveness of continuous low-dose antibiotic prophylaxis for prevention of recurrent UTIs in adult users of CISC.MethodsIn this randomised, open-label, superiority trial, we enrolled participants from 51 UK National Health Service organisations. These participants were community-dwelling (as opposed to hospital inpatient) users of CISC with recurrent UTIs. We randomly allocated participants (1:1) to receive either antibiotic prophylaxis once daily (prophylaxis group) or no prophylaxis (control group) for 12 months by use of an internet-based system with permuted blocks of variable length. Trial and laboratory staff who assessed outcomes were masked to allocation but participants were aware of their treatment group. The primary outcome was the incidence of symptomatic, antibiotic-treated UTIs over 12 months. Participants who completed at least 6 months of follow-up were assumed to provide a reliable estimate of UTI incidence and were included in the analysis of the primary outcome. Change in antimicrobial resistance of urinary and faecal bacteria was monitored as a secondary outcome. The AnTIC trial is registered at ISRCTN, number 67145101; and EudraCT, number 2013-002556-32.FindingsBetween Nov 25, 2013, and Jan 29, 2016, we screened 1743 adult users of CISC for eligibility, of whom 404 (23%) participants were enrolled between Nov 26, 2013, and Jan 31, 2016. Of these 404 participants, 203 (50%) were allocated to receive prophylaxis and 201 (50%) to receive no prophylaxis. 1339 participants were excluded before randomisation. The primary analysis included 181 (89%) adults allocated to the prophylaxis group and 180 (90%) adults in the no prophylaxis (control) group. 22 participants in the prophylaxis group and 21 participants in the control group were not included in the primary analysis because they were missing follow-up data before 6 months. The incidence of symptomatic antibiotic-treated UTIs over 12 months was 1·3 cases per person-year (95% CI 1·1–1·6) in the prophylaxis group and 2·6 (2·3–2·9) in the control group, giving an incidence rate ratio of 0·52 (0·44–0·61; p<0·0001), indicating a 48% reduction in UTI frequency after treatment with prophylaxis. Use of prophylaxis was well tolerated: we recorded 22 minor adverse events in the prophylaxis group related to antibiotic prophylaxis during the study, predominantly gastrointestinal disturbance (six participants), skin rash (six participants), and candidal infection (four participants). However, resistance against the antibiotics used for UTI treatment was more frequent in urinary isolates from the prophylaxis group than in those from the control group at 9–12 months of trial participation (nitrofurantoin 12 [24%] of 51 participants from the prophylaxis group vs six [9%] of 64 participants from the control group with at least one isolate; p...

This study confirms previous findings that ureteroscopic inspection and biopsy provides accurate information regarding the grade and stage of upper-tract TCC. Combining exfoliated cell cytology improves the predictive power of biopsy grade 2 disease for high-risk specimen grade and stage. Our data suggest that ureteroscopic findings may predict muscle invasion.
