The history of urinary diversion

The earliest attempt to divert urine flow from the ureters to the intestine, was performed in 1851 by John Simon. In the absence of antibiotics, ureterosigmoidostomy and its modifications during the 19th and early 20th century have been associated with high rate of surgical and metabolic complications. In 1910, Robert Coffey demonstrated a new method for ureterointestinal anastomosis, which renovated primary enthusiasm in ureterosigmoidostomy and it gained broad popularity during the next forty years. In 1950, Ferris and Odel reported 80% incidence of hyperchloremic metabolic acidosis following ureterosigmoidostomy. Based on further investigations by Lapides in 1951, Parsons, Powel and Pyrah in 1952, and Stamey in 1956, which clearly demonstrated that hyperchloremic metabolic acidosis is inevitable complication of ureterosigmoidostomy, this urinary diversion lost its popularity. In 1950's ileal conduit, popularized by Bricker, became the gold standard for the subsequent 35 years. Early attempts for continent urinary diversion occurred form 1888, by Guido Tizzoni and Alfonso Poggi, while the first reservoir-type ileal loop urinary diversion was performed by Cuneo in 1911. By better understanding of principles of detubularization, based on works of Kock and principles of clean intermittent catheterization, established by Lapides, interest in continent urinary diversion has increased. Up to date, various continent cutaneous stomal reservoirs, sigmoidorectal pouches and orthotopic bladder substitutes have been described. Regarding encouraging improvements in biocompatible materials, alloplastic bladder replacement could be the next step for the future in bladder replacement surgery.
