A modification of the Marshall, Marchetti and Krantz procedure is described that uses the Babcock clamp for exposure and the rectus muscle for suspension in order to reduce the complications and technical difficulties. The procedure was utilized for 30 patients, and in the same period 27 patients were treated with the nonmodified procedure. A follow-up from one to six years resulted in one patient with a complete failure and another with a partial failure in the modified group and five patients with complete failure in the nonmodified group. The complications rates were essentially the same. However, in the nonmodified group there was one patient with osteitis pubis, one patient with urethral stenosis and two patients with prolonged urinary retention. The results suggest that the modified technique is simple and successful in correcting stress urinary incontinence in women if coupled with adequate study of the patient and careful selection of the treatment.
