OBJECTIVES: To review retrospectively our long-term experience with augmentation cystoplasty and simultaneously insertion of artificial urinary sphincter cuff only for lower urinary tract reconstruction in cases of mixed bladder and sphincteric dysfunction. We tried to assess the postoperative continence status, as well as the associated morbidity, focusing upon infections, urethral erosion and revision rates. PATIENTS AND METHODS: Eleven patients with urinary incontinence due to a small capacity and low compliant bladder, combined with incompetent outlet, underwent lower urinary tract reconstruction by augmentation cystoplasty and simultaneous insertion of a bladder neck sphincter cuff only (AMS, model AS-800). Mean age was 29 years (range 18-45). The etiology of voiding dysfunction was a seminal cord injury in 6 patients, myelomeningocele in 2 and spinal cord surgery in 1, bladder exstrophy (1) and pelvic trauma combined with spinal cord injury (1). RESULTS: With mean follow-up period of 115 months (range 45-141), 8 patients (73%) achieved continence on clean intermittent catheterization without any further interventions. Two patients required insertion of sphincter pump and reservoir at a second stage to achieve full continence and subsequently one was removed due to erosion (overall continence rate of 82%). In another patient, the cuff located at the level of the bladder neck has eroded and was removed. None of the patients has experienced an infection of the device in the immediate postoperative period, neither thereafter. CONCLUSIONS: Insertion of sphincter cuff only during augmentation cystoplasty may be sufficient to achieve continence in many incontinent patients who may not be cured by bladder augmentation alone. The procedure is technically easy and is not associated with increased risk of injury to the augmented bladder, neither with subsequent infectious complications.
