[Studer's type ileal neobladder. Study of complications and continence].

Analysis of early and late post-surgical complications in 44 cases of Studer's type bladder replacement due to carcinoma of the bladder performed over a 6-year period. Follow-up ranges between 6 months and 6 years. 4 patients died during the post-operative (9.09%): 1 myocardial infarction, 1 pulmonary embolism and 2 intestinal fistula. 28 patients (63.64%) had post-operative complications: 4 GI fistula (9.09%) 5 ileus (11.36%), 2 GI bleeding (4.54%), 1 ureteral fistula (2.27%), 1 ureteral stenosis, 6 urethro-intestinal fistula (13.36%), 1 tubular necrosis, 1 ruptured ureteral catheter, 5 wound infections (11.36%), 12 urine infections (27.27%), 6 sepsis (13.63%), 1 lymphocele, 1 evisceration and 2 eventrations. Repeat surgery was required in 6 cases. Within 6 months from discharge, 7 of 40 patients (17.5%) had some complication: 3 acute pyelonephritis, 4 episodes of acidosis-dehydration and 1 ureter stenosis. After 6 months, 7 of 38 patients (18.4%) had complications: 1 acidosis, 3 vesical lithiasis, 2 ureteral stenosis and 1 urethro-intestinal, plus 2 cases of chronic urinary retention. Daytime continence was 97.2% and nighttime continence 30%; after 6 months evolution, no further changes were seen.
