CONCOMITANT BLADDER NECK CLOSURE AND MITROFANOFF DIVERSION FOR THE MANAGEMENT OF INTRACTABLE URINARY-INCONTINENCE

In a 7-year period 28 patients 1 to 20 years old have undergone bladde r neck closure in conjunction with Mitrofanoff diversion for the manag ement of severe incontinence. Surgery was performed as a salvage proce dure in 19 patients and as a primary anti-incontinence procedure in 9. At a mean followup of 29 months 27 of 28 patients (96%) were totally continent, requiring no pads. Bladder neck closure was primarily succe ssful in 24 of 28 patients (86%) and 25 (89%) had stable upper tracts. Five patients had bladder calculi and 5 required stomal revisions. On e child had a bladder perforation associated with blunt trauma. Bladde r neck closure and Mitrofanoff diversion were done without bladder aug mentation in 11 cases and augmentation was performed previously or con currently in the remainder. Four patients who did not initially underg o augmentation required later augmentation (2 for hydronephrosis and 2 for persistent incontinence). We conclude that bladder neck closure i n conjunction with Mitrofanoff diversion is highly efficacious in achi eving continence in a highly complex subgroup of patients with intract able urinary leakage. With careful patient selection and diligent foll owup total continence can be achieved in this most difficult patient p opulation.
