Urinary tract stone disease has been found to be a later complication associated with the construction of the Kock pouch continent urinary diversion. Of 383 patients who underwent Kock pouch diversion between August 1982 and December 1986 stones developed in the pouch in 64 (16.7%), usually on exposed staples or eroded Marlex used to construct the nipple valves. Stones have recurred in 13 of the 64 patients (22%). Most stones were removed endoscopically with techniques similar to those used for percutaneous stone removal. Risk factors for stone formation include Marlex collar erosion and acute pyelonephritis. Changes in surgical techniques with elimination of the Marlex collar and a reduction in the number of staples have reduced the incidence of this later complication to 10%.
已发现尿路结石病是与可控性回肠膀胱术（Kock pouch）构建相关的晚期并发症。在1982年8月至1986年12月期间接受Kock pouch改道术的383例患者中，64例（16.7%）在膀胱囊中形成结石，结石通常位于外露的吻合钉或用于构建乳头瓣的被侵蚀的聚四氟乙烯网片（Marlex）上。64例患者中有13例（22%）结石复发。大多数结石通过类似于经皮取石术的技术经内镜取出。结石形成的危险因素包括聚四氟乙烯网片套环侵蚀和急性肾盂肾炎。随着手术技术的改变，取消了聚四氟乙烯网片套环并减少了吻合钉数量，这种晚期并发症的发生率已降至10%。
