Objective: The objective of this study was to reduce the incidence of urinary tract infection (UTI) in women undergoing outpatient cystoscopy and/or urodynamic studies (UDS) at our centre by identifying and then altering modifiable risk factors through an analysis of incidence variability among physicians., Methods: This was a quality improvement study involving adult women undergoing outpatient cystoscopy and/or UDS at an academic tertiary urogynecology practice. Prophylactic practices for cystoscopy/UDS were surveyed and division and physician-specific UTI rates following cystoscopy/UDS were established. In consultation with key stakeholders, this delineated change concepts based on associations between prophylactic practices and UTI incidence, which were then implemented while monitoring counterbalance measures., Results: Two "Plan-Do-Study-Act-Cycles" were conducted whereby 212 and 210 women were recruited, respectively. Change concepts developed and implemented were: (1) to perform routine urine cultures at the time of these outpatient procedures, and (2) to withhold routine prophylactic antibiotics for outpatient cystoscopy/UDS, except in patients with signs of cystitis. There was no change in the incidence of early presenting UTI (9.0% vs. 9.2%, p = 0.680), but there were significantly fewer antibiotic-related adverse events reported (8.5% vs. 1.5%, p = 0.001). There was no significant change in the total incidence of UTI rates between cycles (7.8% vs. 5.6%, p = 0.649)., Conclusions: No specific strategies to decrease the incidence of UTI following outpatient cystoscopy/UDS were identified, however, risk factor-specific antibiotic prophylaxis, as opposed to universal antibiotic prophylaxis, did not increase UTI incidence., (© 2024 Wiley Periodicals LLC.)

Objectives: The objective of the study was to determine practice patterns of prescribing prophylactic antibiotics against urinary tract infection (UTI) for urodynamic studies (UDS) and outpatient cystoscopy in women., Design: A cross-sectional survey study was conducted of North American female pelvic medicine and reconstructive specialists (FPMRS)., Methods: An online survey was used to assess prophylactic prescribing patterns of FPMRS that perform UDS and outpatient cystoscopy. This survey was developed and then electronically disseminated through the American Urogynecologic Society to 699 eligible physicians., Results: A total of 138 surveys were completed. Approximately half of physicians did not prescribe any antibiotic prophylaxis for UDS or for cystoscopy (54% and 43%, respectively). For patients with perceived risk factors (recurrent UTIs, immunosuppression, known neurogenic lower urinary tract dysfunction, indwelling catheter use, elevated postvoid residual/bladder outlet obstruction, genitourinary anomalies, and diabetes), 32% and 41% of physicians prescribed antibiotic prophylaxis for UDS and cystoscopy, respectively. A minority of physicians always prescribed antibiotics for UDS and cystoscopy (13% and 17%, respectively)., Limitations: The response rate was a limitation of the study; however, this rate is in keeping with other physician survey studies published within this subspecialty. Selection and response biases may have contributed to the results of this survey study., Conclusion: There was no uniform approach to UTI prophylaxis for UDS and outpatient cystoscopy in women which reflects the lack of current guidelines and the low level of evidence on which they are based. This nonuniform practice calls for more research to better define an evidence-based standard of care., (© 2022 The Author(s). Published by S. Karger AG, Basel.)

Objective: To compare preoperative vitamin B2 versus intraoperative cystoscopy distension using 5% dextrose in water (D5W) for ureteric jet visualisation during pelvic reconstructive surgery. Design: Double‐blinded, randomised controlled trial. Setting: Three tertiary hospitals in Toronto, Canada. Population Adult women undergoing pelvic reconstructive surgery. Methods: Patients were randomised to receive 100 mg of vitamin B2 preoperatively versus bladder distension with D5W intraoperatively. Main outcomes: The primary outcome was the rate of accurate detection of bilateral ureteric jets during cystoscopy. Secondary outcomes included the time elapsed until visualisation, use of intravenous furosemide or fluorescein to assist with visualisation, surgeon satisfaction, and positive urine culture 1 week after surgery. Results: The intervention was completed by 236 patients (vitamin B2 n = 117, D5W n = 119). Preoperative characteristics were similar across groups. Accurate detection of both ureteric jets was high in both groups (vitamin B2 97.4% vs. D5W 90.8%, p = 0.051). The vitamin B2 group had significantly lower use of fluorescein rescue compared with the D5W group (3.4% vs. 11.8%, respectively, p = 0.025). Surgeon satisfaction while using vitamin B2 was significantly higher (p < 0.001). There were no significant differences in the time elapsed until visualisation, the use of furosemide, or the incidence of positive urine culture at 1 week after surgery. Conclusions: Both preoperative vitamin B2 and intraoperative cystoscopy distension with D5W are highly available and inexpensive methods to detect ureteric jets with high accuracy at the time of pelvic reconstructive surgery. Vitamin B2 was shown to have lower rates of fluorescein rescue for visualisation and higher rates of surgeon satisfaction.
