Urethral instrumentation in men with artificial urinary sphincter: a national survey among Brazilian urologists.

PURPOSE

Urethral instrumentation (UI) in patients with an artificial urinary sphincter (AUS) demands technical considerations and poses a risk of urethral erosion, leading to serious clinical and legal consequences. We conducted a national survey to evaluate the knowledge and experience of Brazilian urologists with UI in these patients.

METHODS

This study used an electronic survey distributed to members of the Brazilian Society of Urology. The survey included 19 multiple-choice questions assessing sociodemographic characteristics, practice patterns, AUS training, knowledge of AUS components and functionality, experience with UI in AUS patients, and interest in further training. Urologists were classified as 'competent' in AUS manipulation if they had prior experience and confidence in performing UI.

RESULTS

Among 536 participants (median age 47 years [39-55]), 72.8% reported involvement in urological emergencies, with 89.9% indicating inadequate AUS training during residency. Only 29.7% had occasional or regular involvement with AUS surgeries. Of the participants, 53.4% had performed UI in men with an AUS. Prior UI had been attempted by healthcare staff in 36.2% of cases. Only 46.8% reported knowledge of AUS components and 45.1% felt competent in deactivating it. Regarding urethral catheterization, 47.2% knew the safe catheter diameter, and 20.9% identified safe catheterization duration. Overall, 45.1% self-declared competence in UI, yet many gave incorrect answers on catheter size and duration. Competence strongly correlated with knowledge of AUS components, regular implant involvement, and prior experience. Most (89.3%) expressed interest in additional training for UI.

CONCLUSION

This study highlights significant gaps in training and knowledge among Brazilian urologists regarding UI in AUS patients. These deficiencies underscore the potential for enhanced education to improve patient outcomes and reduce AUS-associated complications in Brazil and possibly broader international contexts.
