小儿胃膀胱扩大成形术

采用胃膀胱扩大成形术，用于小儿下尿路再建以保护上尿路，控制尿失禁并评价其疗效。３例女性患儿（平均年龄９岁）行带血管蒂胃组织片膀胱扩大成形术。术后随访８个月至２年。３例患儿膀胱容量从术前２０～３０ｍｌ增至２５０～３００ｍｌ，２例排尿控制满意，１例能部分控制排尿。上尿路功能改善２例，稳定１例。血浆电解质成分无改变。胃组织的解剖及代谢特点使胃膀胱扩大成形术不失为小儿下尿路再建的一个重要方法。

Gastrocystoplasty in Children

Cystoplasty with pedicled stomach patch to enlarge the capacity of bladder was performed on 3 girls (mean age of 9 years). Additional operations included ureteral reimplantation(3cases), ureteroureterostomy (2) and bladder neck reconstruction(1). They were followed-up from 8 months to 2 years. The bladder capacity of 3 patients increased from 20-30 ml to 250-300 ml. Continence of urine was achieved in 2 and partial control in 1. Upper urinary function improved in 2 and remained stable in 1. Serum electrolyte kept normal. Gastrocystoplasty should beconsidered as an important choice of reconstruction of lower urinary tract in children.
