[The selection and application of appendix in situ in the continent urinary diversion]

To evaluate the elective method and the clinical experience of using appendix in situ in continent urinary diversion.

26 continent urinary diversions have been performed since 1990. Among them, 11 cases underwent the intussuscepted technique and other 15 cases underwent embedded technique.

The continent rate was 100% at the daytime among all the case, while intermittent incontinence occurred in 3 cases at night, which happened in the intussuscepted group. Other complications included catheterization difficulty in 3 cases, appendix perforation in 1 case, which happened in the embedded group, traction of the appendix into abdominal cavity in 1 case, and prolapse of the intussusepted appendix in 3 cases.

The embedded technique shows better results than the intussuscepted technique in term of continence. The embedded technique, using appendix in situ as an efferent loop, shows the advantages of easily performing, timesaving, better outcome in continence and less complication. We believe the technique of appendix in situ as an efferent loop is an ideal modality in urinary diversion operation.
