Abstract
The clinical and urodynamic results of enterocystoplasty were compared in 3 groups of patients in which the intact ileocecal segment (10 patients), tubular sigmoid segment (16) or sigmoid cup-patch segment (8) was used. In all 3 groups the upper urinary tract and renal function improved or remained stable, and the functional bladder capacity increased. All patients experienced involuntary, volume-dependent vesical contractions of comparable intensity 3 months postoperatively. After a mean followup of 19.4 ± 8.9 months only 12 per cent of the patients with a cup-patch configuration demonstrated volume-dependent contractions, compared to all patients with ileocecal cystoplasty and 94 per cent with sigmoid tubular cystoplasty. The intensity of these contractions was significantly less in the cup-patch configuration group compared to the other groups. Patients with cuppatch cystoplasty achieved a significantly higher rate of urinary continence than those in the other 2 groups.
