Until recently urolithiasis in children following augmentation cystoplasty was an infrequently noted problem. We examined our 10-year experience and found urinary calculi to form in 52% of children and young adults undergoing augmentation cystoplasty. Calculi formed at a median interval of 24.5 months after surgery, predominantly in the lower tract. Urinary tract infection was a statistically significant risk factor, while the use of absorbable staples, intestinal mucus and hypocitraturia were also implicated. Calculus composition was primarily a mixture of apatite, struvite and ammonium urate. Bladder calculi were effectively managed endoscopically in the majority of cases without complication. Upper tract calculi presented an endourological challenge.
直到最近，膀胱扩大成形术后儿童尿路结石仍是一个较少被关注的问题。我们回顾了我们10年的经验，发现接受膀胱扩大成形术的儿童和年轻人中有52%形成了尿路结石。结石形成的中位时间为术后24.5个月，主要位于下尿路。尿路感染是一个具有统计学意义的危险因素，同时可吸收吻合钉的使用、肠道黏液和低枸橼酸尿症也与之有关。结石成分主要是磷灰石、鸟粪石和尿酸铵的混合物。大多数情况下，膀胱结石通过内镜有效处理且无并发症。上尿路结石带来了腔内泌尿外科的挑战。
