Unilateral and bilateral bladder neck suspension (modified Pereyra) operation for stress urinary incontinence.

Stress urinary incontinence can be corrected by a short, simple, minor suturing technique, a modification of the Pereyra operation. Success depends upon careful selection of patients, the proper tightness of the suture over a proper-size catheter and the use of intermittent endoscopy during the operation. Successful outcome up to 7 months has been achieved in 7 of the 8 patients but reoperation was necessary for the successful outcome in 1 of the 2 failures.
