Ileocolic conduit diversion was performed in five patients. Although, the follow-up period is still too short to obtain any conclusive data, satisfactory results were so far observed on the whole. Encountered post-operative complications were urinary leakage in case I and diarrhea and fever attack by pyelonephritis in Case II. They were however transient. IVP, retrograde conduitography, blood chemistry and acid-base balance were examined on the patients. The retrograde conduitography showed that the contrast medium was blocked at the ileocecal valve under the retrograde low pressure irrigation, and no reflux was observed in the ileal portion or ureter. Under the high pressure irrigation, however, the contrast medium passed beyond the ileocecal valve and flowed back to the ureter. Some anatomic and functional advantages of the ileocolic intestinal conduit are discussed. Because the ileocolic vessels are less in variation and easily mobilized, the isolation procedure of the intestinal segment is simpler and the stoma is also easily constructed without any undue tension. The stomal stenosis is expected to be fewer in comparison with the ileal conduit case. This operation is considered to be further examined extensively as one of the conduit type urinary diversions.
