Stress-overflow urinary incontinence after radical hysterectomy and radiation therapy for cervical cancer

A 40-year-old woman was evaluated for urinary incontinence, loss of bladder sensation and residual urine 12 months after radical abdominal hysterectomy and external pelvic radiation therapy for stage IIb cervical cancer. The patient had no history of abnormal lower urinary tract function before treatment. The urodynamic follow-up study at 12 months showed 80 ml of residual urine, low bladder compliance (detrusor pressure of 77 cmH₂O at 200 ml filling) and an incompetent urethral closure mechanism. Cystoscopy showed a pale bladder mucosa with telangiectasia. Two years later the urodynamic findings were almost unchanged, and pudendal nerve terminal motor latency measured according to Snooks and Swash showed prolonged motor latency to the external urethral sphincter. Thus, this patient had combined stress overflow incontinence with pudendal neuropathy and fibrosis of the bladder wall.
