Spontaneous voiding after surgery for urinary incontinence

Eighty patients with urinary incontinence were treated by colposuspension and bladder neck plication. Fourteen patients had difficulty in establishing normal micturition postoperatively. Of these, 10 patients took longer than 21 days to void and had reduced peak urine flow rates after surgery; the other four patients voided within ten days of surgery but had reduced peak urine flow rates before and after surgery and all had residual urines in excess of 100 ml following surgery. The value of the preoperative diagnosis of pre-existent bladder dysfunction by symptomatology and the peak urine flow rate is discussed.
