Long-term followup of 103 patients with bladder exstrophy.

We reviewed 103 patients with exstrophy of the bladder. Followup was more than 15 years in 51 patients. Initial management consisted of primary bladder closure in 32 patients and urinary diversion in 71. Urinary continence, renal function, urinary tract infections and development of malignant lesions were evaluated. Factors leading to success or failure were analyzed. Although the highest continence rate (83 per cent) was achieved in 40 patients with ureterosigmoidostomy, renal functional deterioration was highest in this group, with 70 per cent of the evaluable renal units being abnormal. Furthermore, 10 per cent of this group died of renal failure and 23 per cent lost 1 kidney each. In 26 patients with an ileal conduit 69 per cent of the renal units evaluated were abnormal. Only 1 patient died of renal failure but 27 per cent lost 1 kidney each. Of 32 patients with primary bladder closure 31 had preservation of renal function. Twelve of 18 patients (67 per cent) in whom vesical neck reconstruction had been completed had total urinary continence and 3 (17 per cent) had partial continence. The incidence of significant urinary tract infections was highest in the ureterosigmoidostomy group (63 per cent) and next to the highest in the ileal conduit group (48 per cent). Malignant lesions developed in 8 patients (8 per cent).
