[Analysis of early and late complications and their origins in Kock continent urinary reservoir following technical modification].
Kock and associates have made a major contribution to the ideal continent urinary diversion by developing a method for creating a continent internal reservoir for urine using the ileum. However, substantial problems have unfortunately resulted due to early and late postoperative complications. In an effort to further elucidate this problem, we herein summarize the incidence of early and late postoperative complications following a series of technical modifications made in patients who underwent Kock continent ileal reservoir construction from our ongoing experience to develop more suitable modifications of this procedure. From January 1985 through December 1991, 47 patients have undergone Kock pouch construction for continent urinary diversion. Our basic technique utilized in this study was slightly modified from that described by Skinner et al. Based on our earlier experience, several changes in the technique were made. One major change is that one row of surgical staples fixes the created nipple to the back wall of the reservoir for the efferent limb, and a further 3-cm longitudinal mucosal incision is made through the outer layer of the intussuscepted ileal nipple and the opposite wall of the reservoir which are sewn to the reservoir edge. A total of eleven patients (11/47) suffered one or more early surgical complications. A 31.8% (7/22) morbidity with an operative mortality rate of 4.3% (2/47) and a 16.0 (4/25) morbidity were observed in the early phase and late phase, respectively. Prolonged urinary leakage from the ileal reservoir and/or through a pin hole in the afferent limb made by surgical staples was observed in six patients (27.3%) in the early phase.(ABSTRACT TRUNCATED AT 250 WORDS)
