Results of bladder neck reconstruction using bladder flaps in complex female urethral defects

Area of Science:

• Urology
• Reconstructive Surgery

Background:

• Female urethral defects are rare and challenging to manage, often leading to incontinence or urinary retention.
• Limited experience has resulted in a lack of standardized management protocols for these conditions.

Purpose of the Study:

• To evaluate the efficacy of anterior or posterior bladder wall flaps in managing diverse female urethral defects.
• To describe the outcomes of reconstructive surgery for complex urethral abnormalities.

Main Methods:

• A retrospective review of 22 patients who underwent anterior or posterior bladder wall flap procedures for complex urethral defects.
• Patient assessment included history, physical and pelvic examination, cysto-urethroscopy, and imaging to guide surgical selection.

Main Results:

• Anterior bladder flaps were used in 16 patients, and posterior flaps in 6 patients.
• Postoperatively, 18 patients achieved social continence, and 15 had complete continence with satisfactory voiding.
• Four patients experienced persistent incontinence, and two developed voiding difficulties requiring self-calibration.

Conclusions:

• Female urethral defects, particularly those involving the bladder neck, present significant management challenges.
• Bladder wall-based flaps provide a viable and successful reconstructive option for complex female urethral defects.
