Objective To describe a modified form of detubularization using a perimesenteric incision of the ileal segment, which increases the capacity of the neobladder and reduces the length of the ileal segment required. Patients and methods From February 1993 to November 1999, ileocystoplasty was undertaken in 20 patients (mean age 8.4 years, range 4–16). Six had myelodysplasia, four had primary epispadias, five had bladder exstrophy, three had post‐traumatic lesions and two had cloacal exstrophy. The patients were divided into two groups; in the first (eight patients, mean age 9.6 years, range 5–15) the ileal segment was opened along the antemesenteric border and in the second (12 patients, mean age 7.7 years, range 4–16) the ileal segment was opened adjacent to the mesentery, perimesenterically. Each segment was then folded and the perimesenteric edges sutured to form the pouch. Results The patients were assessed at 1 year after surgery; the neobladder capacity was evaluated as ((neobladder capacity − bladder capacity)/body weight), which shows the relative increase of bladder capacity after enterocystoplasty per unit of weight. There was a statistically significant increase in neobladder capacity in group 2 (perimesenteric transection; Kruskal–Wallis chi‐square, P = 0.005; Mann–Whitney U ‐test, P = 0.006). Conclusion These results indicate that augmentation can be carried out by perimesenteric transection of the intestinal segment, which improves compliance and increases capacity of the neobladder.
