Kock continent ileal reservoir has been one of the major options of urinary diversion for the patients with bladder cancer. We performed Kock pouch operation in 16 patients (male 12, female 4; from 41 to 66 years old, mean age 57 years old). Since the reservoir function of Kock pouch after a long postoperative period is not well known, we examined the volume capacity, the compliance and the length of efferent valve of Kock pouch in 8 patients during a 3-year postoperative period. Although the compliance was stable, the volume capacity and the length of the efferent valve showed a decreasing tendency. The shorter efferent valve was not always associated with the case of urinary incontinence. Most of the complications in 15 patients was trouble of efferent valve (prolapse of efferent valve in 7 cases and eversion or fistula formation that required reconstruction surgery in 3 cases). Although some complications were observed, the reservoir function of the pouch was stable. Therefore this method is reliable for permanent urinary diversion.
科克可控回肠膀胱术一直是膀胱癌患者尿流改道的主要选择之一。我们对16例患者（男性12例，女性4例；年龄41至66岁，平均年龄57岁）实施了科克膀胱术。由于术后很长一段时间内科克膀胱的储尿功能尚不为人所知，我们在术后3年期间对8例患者的科克膀胱的容量、顺应性和输出瓣长度进行了检查。尽管顺应性稳定，但容量和输出瓣长度呈下降趋势。输出瓣较短并不总是与尿失禁情况相关。15例患者中的大多数并发症是输出瓣问题（7例输出瓣脱垂，3例出现外翻或瘘管形成需要重建手术）。尽管观察到了一些并发症，但膀胱的储尿功能是稳定的。因此，这种方法对于永久性尿流改道是可靠的。
