The replacement of lost ureter with bowel interposition is a feasible alternative in the reconstruction of the urinary tract. When adequate ureteral length is not present, interposition of a portion of small bowel between the proximal and distal ureteral segments is an option that minimizes the amount of bowel in the urinary tract. This, in turn, reduces mucus production and electrolyte absorption in the reconstructed urinary tract, and allows for more bowel to remain as part of the functioning gastrointestinal tract. This procedure allows use of the antirefluxing function of the normal ureterovesical junction when present. We have used successfully interposition of the small bowel between the proximal and distal ureteral segments for undiversion in 5 children. Generally, we strive to join urothelium to urothelium without the use of bowel in urinary tract reconstruction but when this is not feasible, bowel interposition has been a useful option.
用肠管替代缺失的输尿管是尿路重建中一种可行的替代方法。当输尿管长度不足时，在输尿管近段和远段之间置入一段小肠是一种选择，可使尿路中的肠管量减至最少。这进而减少了重建尿路中的黏液分泌和电解质吸收，并使更多的肠管作为正常胃肠道的一部分得以保留。该手术可利用正常输尿管膀胱连接部的抗反流功能（若存在的话）。我们已成功地为5名儿童在输尿管近段和远段之间置入小肠以恢复尿路改道。一般来说，我们在尿路重建中力求将尿路上皮与尿路上皮吻合，而不使用肠管，但当这不可行时，肠管置入一直是一种有用的选择。
