Bowel is used in urological surgery to replace the bladder, either as a conduit to drain urine to the abdominal wall as a urinary stoma or refashioned to form a substitute bladder. Many factors contribute to stone formation, being urinary stasis, mucus production and bacteriuria the most important. Metabolic changes induced by exposure of segments of the alimentary tract to urine promote struvite, calcium oxalate and calcium phosphate stone formation. Generally, the majority of patients with stones in a urinary diversion can be treated with minimally invasive techniques. Open surgical removal is considered when other modality of treatments cannot be accomplished safely and expeditiously.
在泌尿外科手术中，肠道被用于替代膀胱，既可以作为将尿液引流至腹壁形成尿造口的导管，也可以重新塑形以形成替代膀胱。结石形成受多种因素影响，其中最重要的是尿潴留、黏液产生和菌尿。消化道节段暴露于尿液所引起的代谢变化会促进磷酸镁铵、草酸钙和磷酸钙结石的形成。一般来说，大多数尿流改道患者的结石可以采用微创技术治疗。当无法安全、迅速地完成其他治疗方式时，则考虑进行开放手术切除。
