RESUMEN
Introduction: Societal guidelines offer a weak recommendation to perform cystoscopy for female patients with recurrent urinary tract infections (rUTI) of advanced age and/or with high-risk features. These guidelines lack the support of robust data and are instead based on expert opinion. In this retrospective cohort study, we aim to determine the utility of cystoscopy in patients with and without high-risk features for rUTI. Materials and methods: We identified 476 women who underwent cystoscopy for the evaluation of rUTI at a single tertiary academic medical center from May 1, 2015 and March 15, 2021. Patients were excluded if they had a competing indication for cystoscopy. Risk factors, demographic information, cystoscopic findings, and patient outcomes were analyzed. Results: 192 (41.1%) were classified as having complicated UTI. We identified six patients (1.3%) with findings that prompted management to significantly impact patient outcomes. All six patients had high-risk features. 14 patients (3.0%) were found to have mucosal abnormalities prompting biopsy, three of which required general anesthesia. All 14 biopsies were ultimately benign. Conclusions: Our findings demonstrate a low diagnostic yield and increased risk exposure for women undergoing cystoscopy for the evaluation of complicated rUTI. Additionally, our observations support prior studies indicating that cystoscopy has limited utility in the evaluation of rUTI without high-risk features.
RESUMEN
Objectives: There is presently scarce literature describing the outcomes of patients undergoing robotic ureteral reconstruction (RUR) using the Boari flap (BF) technique. Herein, we report our prospective, multi-institutional experience using BF in patients undergoing robotic urinary reconstruction. Patients and Methods: We reviewed our prospective, multicenter database for all patients undergoing RUR between September 2013 and September 2021 in which a BF was utilized. Preoperative, perioperative, and follow-up data were collected and analyzed. Major complications were defined as a Clavien-Dindo classification grade >2. Surgical failure was defined as recurrent symptoms, obstruction on imaging, or the need for additional surgical interventions. Results: We identified 50 patients who underwent RUR using a BF. Four (8%) underwent the Single Port approach. Twenty-four patients (48%) were active or former tobacco users. Thirty-four patients (68%) had previously undergone abdominal surgery, 17 (34%) had prior ureteral stricture interventions, and 9 (18%) had prior abdominopelvic radiation. The most common stricture etiology was malignancy (34.4%). The median follow-up was 15.0 months with a 90% (45/50) success rate. The five documented cases of failure occurred at a median of 1.8 months following the procedure. Conclusion: In the largest prospective, multi-institutional study of patients undergoing RUR with BF in the literature to date, we demonstrate a low rate of complications and a high rate of surgical success in three tertiary academic medical centers. All observed failures occurred within 2 months of surgical intervention.
