ABSTRACT Background Ureteral stents are commonly placed during kidney transplantation (KT) to mitigate urologic complications. The objective of this study was to compare clinical outcomes in KT recipients with either early stent removal when attached to the Foley catheter or late removal via cystoscopy when unattached. Methods We conducted a multi‐center retrospective analysis of consecutive living donor KT patients (8/18/21‐4/21/23) stratified into Foley‐attached and unattached stent groups. Outcomes assessed were ureteral stricture, urine leaks, UTIs at 90 days and allograft failure and BKV DNAemia (BK virus DNAemia) at 1 year. Data are reported as mean and standard deviation. Results Among 247 patients with attached and 260 with unattached stents, baseline demographics (age, sex, diabetes) were similar between groups. There was a difference in race (87.9% vs. 77.8% Caucasian; p = 0.004). Foley catheters remained longer in the attached group (3.7 ± 1.8 vs. 3.0 ± 2.0 days; p < 0.001), but stents were removed earlier (3.7 ± 1.8 vs. 21.9 ± 4.7 days; p < 0.001). Comparing attached versus unattached, there were no differences in ureteral stricture (0.4% vs. 1.5%; p = 0.197), urine leak (0.8% vs. 0.4%; p = 0.533), BKV DNAemia (17.7% vs. 16.9%; p = 0.616), or allograft failure (0% vs. 0.8%; p = 0.167). However, UTI incidence by 90 days was lower in the attached group (5.7% vs. 11.9% p = 0.013). Induction therapy differed significantly between groups, with Alemtuzumab more common in the unattached group (58.1% vs. 19.4%, p < 0.001), Basiliximab more common in the attached group (43.3% vs. 35.0%, p < 0.001), and Thymoglobulin more common in the attached group (36.0% vs. 6.9%, p < 0.001). Baseline steroid use was higher in the unattached group (81.9% vs. 57.9%, p < 0.001). Conclusion Early stent removal via connection to the Foley catheter had similarly low rates of ureteral complications while reducing urinary tract infections and avoiding cystoscopic removal.

Abstract Background As perception of penile curvature varies widely, we sought to understand how adults perceive curvature and how these opinions compare with those of patients with curvature, specifically Peyronie’s disease (PD). Aim To investigate the perspectives of curvature correction from adults with and without PD, as well as differences within demographics. Methods A cross-sectional survey was administered to adult patients and nonpatient companions in general urology clinics at 3 institutions across the United States. Men, women, and nonbinary participants were recruited. Patients were grouped as having PD vs andrology conditions without PD vs general urology conditions plus companions. The survey consisted of unlabeled 2-dimensional images of penis models with varying degrees of curvature. Participants selected images that they would want surgically corrected for themselves and their children. Univariable and multivariable analyses were performed to identify demographic variables associated with willingness to correct. Outcomes Our main outcome was to detect differences in threshold to correct curvature between those with and without PD. Results Participants were grouped as follows: PD (n = 141), andrology (n = 132), and general (n = 302) . Respectively, 12.8%, 18.9%, and 19.9% chose not to surgically correct any degree of curvature (P = .17). For those who chose surgical correction, the mean threshold for correction was 49.7°, 51.0°, and 51.0° (P = .48); for their children, the decision not to correct any degree of curvature was 21.3%, 25.4%, and 29.3% (P = .34), which was significantly higher than correction for themselves (P &lt; .001). The mean threshold for their children’s correction was 47.7°, 53.3°, and 49.4° for the PD, andrology, and general groups (P = .53), with thresholds no different vs themselves (P = .93). On multivariable analysis, no differences were seen in demographics within the PD and andrology groups. In the general group, participants aged 45 to 54 years and those who identified as LGBTQ (lesbian, gay, bisexual, transgender, queer) had a higher threshold for correction as compared with their counterparts when factoring other demographic variables (63.2° vs 48.8°, P = .001; 62.1° vs 50.4°, P = .05). Clinical Implications With changing times and viewpoints, this study stresses the importance of shared decision making and balancing risks and benefits to correction of penile curvature. Strengths and Limitations Strengths include the broad population surveyed. Limitations include the use of artificial models. Conclusion No significant differences were seen in the decision to surgically correct curvature between participants with and without PD, with participants being less likely to choose surgical correction for their children.

AbstractAimsIntraoperative defibrillation testing (DT) during implant or replacement of implantable cardioverter-defibrillators (ICDs) has been a matter of debate for many years. This debate was put to rest by the Simple and Nordic ICD trials, and the practice of testing during new implantations has essentially been almost abandoned. Old registries demonstrated an increased incidence of significant findings in DT during replacements. The aim of the present study was to evaluate frequency of significant findings and safety of DT in subjects undergoing device replacement.Methods and resultsA prospective observational multi-centre study included consecutive patients undergoing ICD generator replacement. The primary outcome was a failure to terminate induced ventricular fibrillation (VF) with a single shock 10 J below the maximal capacity of the device. Secondary outcomes included complications of DT. Patients were followed-up at 1- and 6-months post-procedure. A total of 92 patients were eligible, and consented to the study, of which 84 underwent DT during battery replacement. The median age was 68 years and 79.8% were males. Induction of VF was successful in 84 patients as was a successful conversion on the first attempt in all. There were no procedure-related complications. During follow up one patient had two appropriate ICD shock events. In four patients, ICD programming was changed. None suffered inappropriate shock. There was no evidence of lead malfunction. Two deaths occurred, none of which was related to arrhythmia.ConclusionThe present study found DT was not associated with complications in patients undergoing ICD generator replacement but produced no clinically important information.

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): Maurice Kahn Foundation via the Mayo- Sheba Collaboration Fund. Background The need for intraoperative defibrillation testing (DFT) during implant and/or replacement of implantable cardioverter-defibrillators (ICDs) has been a matter of debate for many years. This debate was put to rest by the Simple and the Nordic ICD trials, and the practice of testing during new implantations has practically been nearly abandoned. Nevertheless, induction of VF for testing purposes (VFT) may still have an important role in selective populations at risk for defibrillation failure, who were not included in the SIMPLE and Nordic trials. One such population includes those who undergo device replacements. Old registries demonstrated an increased incidence of significant findings in VFT during replacements. In the present study, we sought to test this observation. Objectives Evaluate frequency of significant findings and the safety of VFT in subjects undergoing device replacement. Methods A prospective observational multi-center study of VFT included consecutive patients undergoing ICD generator replacement in 5 centers in Israel, Europe, and the US. All centers followed the same VFT protocol. The primary outcome was defined as failure to terminate induced VF with a single shock at 10 Joules below the maximal capacity of the device. Secondary outcomes included complications of VFT. Patients were followed-up at 1 month and 6 months post-procedure. Data collection included documentation of any peri-operative complications and clinical endpoints (occurrence of appropriate shock, inappropriate shocks, lead failure, need for re-intervention, and infection). Results A total of 92 patients were eligible, and consented for the study, of which 84 underwent DFT during battery replacement. The median age was 68 years and 79.8% were male subjects. Induction of VF was successful in all 84 patients as well as VFT with a successful conversion on first attempt. During follow up one patient had two appropriate ICD shock events. In four patients, the ICD programming was changed. None suffered an inappropriate shock. There was no evidence of lead malfunction. A total of two deaths occurred, none of which were related to the device. Conclusion The present study found VFT was not associated with complications in patients undergoing ICD/CRTD generator replacement but produced no clinically important information.
