Upper urinary tract condition after cystectomy with urine diversion into an artificial bladder

Of the many proposed methods of urine diversion during cystectomy operations, ureterosigmostomy continues to be the most common. However, the diversion of urine into the large intestine is known to cause a high mortality rate from pyelonephritis and renal failure. L. N. Pogozheva (1967) reports that all 16 patients observed by her, who underwent ureteral transplantation into the intestine as a preparatory stage for cystectomy, died in the first six months after the operation from pyelonephritis and renal failure. Immediate mortality from pyelonephritis and renal failure, according to A. P. Tsulukidze and D. D. Murvanidze (1955), is 24%, and in later periods this percentage increases significantly. Of our 28 patients who underwent cystectomy and ureterosigmostomy, 21 died from pyelonephritis and renal failure in a period from 1 week to 1.5 years.
