A new technique for urinary reservoir reconstruction has been applied to 14 patients following radical cystectomy. The sigmoid colon was used in 10 cases and the ileum in 4. The pouch is constructed of adjacent detubularized intestinal segments. The continence mechanism is achieved by the formation of a double-jacket intestinal tube anastomosed to the skin. All patients except 1 were continent during stressful situations and resting with easy catheterization of the pouch. Urodynamic study in 3 cases showed a low pressure sigmoid reservoir with an average of 15 cm. water, and the tube had good tone with an average of 35 cm. water and a 5.5 cm. functional length. The technique is simple, can be applied to either the sigmoid colon or ileum and results in urinary continence with easy catheterization.
一种新的尿流改道重建技术已应用于14例根治性膀胱切除术后的患者。其中10例采用乙状结肠，4例采用回肠。贮尿囊由相邻的去管化肠段构建而成。通过形成与皮肤吻合的双层肠管实现控尿机制。除1例患者外，所有患者在应激状态下均能自主排尿，且贮尿囊易于导尿。3例患者的尿动力学研究显示，乙状结肠贮尿囊压力较低，平均为15厘米水柱，肠管张力良好，平均为35厘米水柱，功能长度为5.5厘米。该技术操作简单，可应用于乙状结肠或回肠，能实现尿失禁患者自主排尿且易于导尿。
