Urolithiasis in children following augmentation cystoplasty.
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.
