Female Urethroplasty Using a Labia Minora Flap: A Case Report

Female urethral stricture (FUS) is a rare condition contributing to bladder outlet obstruction in women with lower urinary tract symptoms. This case report details a 54-year-old female patient presenting with voiding difficulties following multiple traumatic catheterizations. Diagnostic tests revealed a maximum urine flow rate of 6.9 ml/sec and a significant post void residual volume of 280 ml. Under general anesthesia, urethroplasty was performed using a labia minora pedicle flap. The procedure involved dissecting the periurethral tissues, preparing an appropriate-sized flap from the right labia minora, and suturing it to close the incised distal urethral stricture over a 20 Fr catheter. Postoperative recovery was successful, with uroflowmetry showing a maximum urine flow rate of 35.7 ml/sec and no residual urine 1 month after surgery. At the 1-year follow-up, the patient reported no further voiding issues, demonstrating the efficacy of the labia minora flap technique for FUS repair.
