One day after giving birth to a 4050-g (8-lb 15-oz) male newborn, a 22-year-old woman experiences involuntary loss of urine. The urine loss occurs intermittently in the absence of an urge to urinate. It is not exacerbated by sneezing or coughing. Pregnancy was uncomplicated except for two urinary tract infections that were treated with nitrofurantoin. Delivery was complicated by prolonged labor and severe labor pains; the patient received epidural analgesia. Her temperature is 36.2°C (97.2°F), pulse is 70/min, and blood pressure is 118/70 mm Hg. The abdomen is distended and tender to deep palpation. Pelvic examination shows a uterus that extends to the umbilicus; there is copious thick, whitish-red vaginal discharge. Neurologic examination shows no abnormalities. Which of the following is the most likely cause of this patient's urinary incontinence?
