Abstract
A survey of indications, technics and results of various technics for bladder replacement or enlargement is presented. Only methods preserving the connection between urethra and new bladder are discussed. The report is based on the authors experience in 141 patients operated on during a period of 8 years. The method using excluded sigmoid segment for bladder replacement seems to be most suitable. This judgement is based on the observation of late functional results which are distinctly better in cases of sigmoid new bladder. The overall postoperative mortality rate of 5,6% is not exaggerated and it can still be lowered in the future as well as a relatively high incidence of other nonmortal postoperative complications. The technic using a based peritoneal flap for reconstruction of the bladder wall is estimated as suitable for replacement of not more than half of the bladder wall.
