RESUMEN
INTRODUCTION AND HYPOTHESIS: Female urethral defects are rare, congenital defects being more uncommon than acquired, and difficult to manage. Most female urethral defects are associated with incontinence or acute urinary retention. There is a lack of standard protocol-based management of female urethral defects because of limited experience. In this study, we describe our results of using anterior or posterior bladder wall flaps in the management of a variety of female urethral defects. METHODS: We reviewed the case records of 22 patients who had undergone either anterior or posterior bladder wall-based flap procedures for complex urethral defects at our institute. Patients were assessed by taking a comprehensive history including aetiological factors and details of prior surgical intervention, thorough physical and pelvic examination, cysto-urethroscopy and relevant imaging. These factors, along with availability and status of tissue available for reconstruction affected the selection of procedure for reconstruction. RESULTS: Out of 22 patients, anterior and posterior bladder flaps were used in 16 and 6 patients respectively. A total of 18 patients became socially dry and 15 achieved complete continence after removal of the catheter and were voiding satisfactorily, whereas the remaining 4 patients had incontinence postoperatively. An additional 3 out of 18 patients had minimal stress incontinence requiring conservative treatment and 2 patients developed voiding difficulty requiring self-calibration. CONCLUSIONS: Female urethral defects with bladder neck involvement are complex and challenging to manage. Bladder wall-based flaps offer a good chance of successful repair of these complex urethral defects.
