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 expediously.
