Intravesical prostaglandin F2 for promoting bladder emptying after surgery for female stress incontinence.

Prostaglandin F2 alpha 10 mg was administered intravesically in a double-blind placebo-controlled study to promote micturition in cases of urinary retention after operative treatment of urinary stress incontinence in women. Fifteen of 18 patients (83%) succeeded in voiding after treatment with prostaglandin F2 alpha, but the placebo was ineffective in all 18 patients (P less than 0.001). Although the effect of prostaglandin F2 alpha on bladder muscle contraction was short-lived, it seemed to enhance the restoration of bladder motor function with no serious side effects, and thus to be clinically useful in the treatment of post-operative urinary retention.
