The ileocecal reservoir (Indiana pouch) is a large volume, low pressure continent reservoir well suited for urinary diversion. The mechanism of continence is believed to be the result of several factors, including the natural ileocecal valve resistance, resistance produced by the plication of the ileal segment and normal peristalsis of the ileum. We report the results of a video-urodynamic study in patients with an Indiana pouch, aimed at establishing the factors that contribute to continence and their relative significance. Video-urodynamic studies clearly demonstrate that continence in this type of urinary reservoir is dependent upon a synergism of the aforementioned factors in combination with the low intraluminal pressure of the detubularized bowel. Video-urodynamic studies offer an objective demonstration of the reservoir dynamics and its continence mechanisms, and provide an insight into the possible etiology of incontinence. Such studies also offer an objective means for critical comparison of the different continent urinary reservoirs.
回盲部储尿囊（印第安纳袋）是一种大容量、低压的可控性储尿囊，非常适合尿液改道。控尿机制被认为是多种因素共同作用的结果，包括天然回盲瓣的阻力、回肠段折叠产生的阻力以及回肠的正常蠕动。我们报告了对印第安纳袋患者进行视频尿动力学研究的结果，旨在确定促成控尿的因素及其相对重要性。视频尿动力学研究清楚地表明，这种类型的尿液储器的控尿取决于上述因素与去管状肠腔内低压的协同作用。视频尿动力学研究客观地展示了储尿囊的动力学及其控尿机制，并深入了解了尿失禁的可能病因。此类研究还为不同可控性尿液储器的关键比较提供了一种客观方法。
