Objective: Endoscopic upper urinary tract instrumentation is a common urological procedure; often associated with prior ureteric stenting and postoperative urosepsis. This study aimed to explore the clinical utility of preoperative urine and intraoperative urine and ureteric stent cultures in the management of urosepsis post upper urinary tract instrumentation. Methods: Prospective study involving pre-stented patients whose upper urinary tract was instrumented at a single centre between 2017 and 2018. Five cultures were collected per patient. Patients were tracked for development of postoperative urosepsis. Results: The study included 227 patients, with a 5.7% postoperative urosepsis rate. Risk of urosepsis was significantly associated with female gender, steroid use and having a colonized preoperative urine culture, intraoperative bladder urine or stent-end culture, or kidney urine culture. Patients with a colonized intraoperative bladder urine were 11 times more likely to develop urosepsis and were colonized with the same organism isolated from urosepsis cultures for 50% of cases. Conclusions: To our knowledge this is the largest cohort study which analyses five different urinary tract cultures and the relationship with postoperative urosepsis. A positive intraoperative bladder urine culture is an independent predictor of postoperative urosepsis development and causative organism, which could guide antibiotic management for these patients.

Background/Objectives: Penile fractures are a rare urological emergency, defined as the traumatic rupture of the tunica albuginea. They are classically diagnosed on clinical grounds, requiring urgent operative repair, most commonly by penile degloving. Magnetic resonance imaging (MRI) has emerged as a promising tool in the management of penile fractures. Often recommended in the setting of equivocal clinical diagnoses, MRI can help diagnose, as well as localise, the site of injury. Furthermore, it also holds potential in differentiating penile fractures from mimicking conditions, thereby possibly preventing unnecessary surgical procedures. This study is aimed at evaluating the diagnostic accuracy of MRI for penile fractures. Furthermore, it seeks to explore MRI’s effectiveness in guiding the surgical approach through precise localisation of the injury site. Methods: The PubMed, Embase, and Cochrane databases were searched from January 1995 to December 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and a total of 246 cases from 32 studies were identified. Results: Pooled results for MRI use in penile fracture diagnosis resulted in a positive predictive value of 97.8%, a negative predictive value of 87.0%, a sensitivity of 98.6%, and a specificity of 80%. MRI can accurately guide localised incisions, due to its ability to accurately identify the exact site of injury, with no additional reported complications or conversions to degloving. Considerable heterogeneity was observed within MRI parameters and protocols used in the studies identified. Conclusions: This review suggests that MRI is an accurate imaging modality for penile fractures and should be considered as a first-line investigation for equivocal cases. Its application may refine clinical management by avoiding unnecessary surgeries in cases mimicking penile fractures and improve pre-operative planning through precise injury localisation. This study is limited by heterogeneity in MRI protocols and the small sample sizes and retrospective nature of many included studies. The future standardisation of MRI protocols could enhance its utility and reliability in the clinical setting. Additionally, further research is needed to evaluate the long-term outcomes following the repair of small fractures detected on MRI and following MRI-guided localised incisions during surgical repair.

Objectives: To describe the surgical approach and perioperative outcomes of a multicenter series evaluating a robotic-assisted approach to radical cystectomy with total intracorporeal urinary diversion in the setting of prior pelvic radiotherapy. Materials and methods: We analyzed our prospective cystectomy database for patients who underwent robotic-assisted radical cystectomy for bladder cancer after radiotherapy between 2018 and 2022. Demographic information and data regarding preoperative factors including stage of disease, preoperative hydronephrosis, and history of pelvic radiotherapy were collected via review of electronic medical records. All operations were performed by 1 of 2 experienced urologists using the da Vinci X, Xi, or Si surgical platforms. Results: Ten patients were identified for this study. The median age of participants was 73.5 years (range, 41–84 years). The median American Society of Anesthesiologists classification score was 3 (range, 3–4). The median Charlson Comorbidity Index was 6 (range, 2–12). Among the patients, 4 out of 10 patients (40%) had muscle invasive bladder cancer before salvage surgery. Intracorporeal ileal conduit urinary diversion was performed in 8 patients, whereas 2 patients underwent intracorporeal neobladder formation. Median intraoperative blood loss was 250 mL (range, 150–600 mL), and median operative duration was 390 minutes (range, 195–450 minutes). The overall 30-day complication rate was 60% with a Clavien-Dindo grade ≥3 complication rate of 15%. Perioperative mortality was 0%. Median duration of follow-up was 210 days (range, 60–1580 days). Conclusions: This series describing the outcomes of salvage robotic-assisted radical cystectomy using total intracorporeal urinary diversion demonstrates the safety of this technique. Further studies with long-term follow-up, including oncological outcomes, are required to support the widespread adoption of this procedure.

Background/Objectives: Ureteric stents are commonly used in the management of urolithiasis but are associated with significant morbidity, leading to unplanned emergency department presentations and increased healthcare utilisation. This study aimed to evaluate whether reducing ureteric stent dwell time from three months to one month was associated with reduced stent-related emergency presentations. Secondary objectives were to assess post-ureteroscopy infective complications and identify predictors of emergency attendance. Methods: A retrospective cohort study was conducted across Western Sydney Local Health District, comparing patients undergoing ureteric stenting prior to ureteroscopy before (n = 189) and after (n = 244) an institutional policy change reducing time to definitive surgery from three months to one month. Patients aged ≥16 years with urolithiasis were included. Results: Following the policy change, mean waiting time for ureteroscopy decreased from 97.3 to 40.6 days. The proportion of patients presenting to the emergency department (ED) for stent-related symptoms decreased from 31.7% to 16.4% (p < 0.001), and mean presentations per patient declined from 0.60 to 0.21 (p < 0.001). Stent irritation accounted for most presentations. Using multivariable analysis, age < 50 years, immunosuppression, and positive pre-operative urine cultures were independently associated with ED attendance. Post-ureteroscopy infective complications were lower in the shortened dwell-time cohort (2.0% vs. 4.2%) but did not reach statistical significance (p = 0.26). Conclusions: Reducing routine ureteric stent dwell time from three months to one month was associated with significantly fewer stent-related emergency presentations. Shorter dwell protocols may reduce patient morbidity and healthcare utilisation and could be associated with lower rates of post-ureteroscopy infective complications.
