Clam ileocystoplasty: successful treatment of severe bladder overactivity.

When conservative treatment for bladder overactivity fails the "clam" ileocystoplasty has been proposed to restore continence and preserve urethral voiding. This study presents our experience with this technique.


Thirty patients, 4 men and 26 women, with a mean age of 50.3 years (range 21-71 years) were operated upon. Five patients had an incomplete spinal lesion and detrusor hyperreflexia, 25 subjects had an idiopathic, unstable detrusor. The ileocystoplasty was combined with a colposuspension procedure in 8 patients. In one patient simultaneous repair of an urethro-vaginal fistula was performed using omentum flap interposition. The mean follow-up was 60 months (range 4-127).


To the surgeon, 27 patients (90%) reported satisfaction with bladder control and relief of symptoms at follow-up. When asked by a nurse in a written questionnaire, 18 out of 23 patients (78%) were quite happy with their bladder function postoperatively. No serious complications to surgery were noted. Postoperatively, 11 patients used self-intermittent catheterization and one, by choice, preferred an indwelling catheter. Due to failure, two patients later underwent reoperation with urinary diversion and one further patient required an additional artificial sphincter. Metabolic consequences owing to enteric malabsorption were infrequent and of a mild nature. No malignant change was identified.


In patients with refractory overactive bladder, we found the "clam" ileocystoplasty to be an effective technique for symptom reduction and increased quality of life.
