Intestinal segments in various forms have been used to reconstruct the urinary tract since the mid-1800s. Currently, many different forms of continent and incontinent diversion options exist. Incorporating bowel mucosa within the urinary tract leads to predictable metabolic and nutritional consequences. The use of ileum or colon can cause a hyperchloremic metabolic acidosis, vitamin B12 deficiency, osteoporosis, fat malabsorption, urinary calculi, and ammoniagenic encephalopathy. Due to metabolic and nutritional consequences associated with the use of jejunum and gastric segments, the use of these bowel segments is not recommended.
自19世纪中叶以来，各种形式的肠段已被用于重建尿路。目前，存在许多不同形式的可控性和不可控性尿流改道术选择。将肠黏膜纳入尿路会导致可预测的代谢和营养后果。使用回肠或结肠会导致高氯性代谢性酸中毒、维生素B12缺乏、骨质疏松、脂肪吸收不良、尿路结石和产氨性脑病。由于使用空肠和胃段会带来代谢和营养方面的后果，因此不建议使用这些肠段。
