[Perforation in TUR].

In the TUR, particularly in clinical teaching is always to be reckoned with extraperitoneal perforation, atypical intraperitoneal perforations are to be taken into consideration. On the other hand it is necessary to prevent the development of a perforation-syndrome. The cystogram has the highest diagnostic value and is at the same time decision aid for the rapid performance of operative and conservative measures. Also with regard to the not infrequent subclinical through-resections the cystogram should become routine examination after every TUR. A clear directive for the resection team and the carrying-through of a consequent behaviour regime for the nursing staff of the hospital are the basis of a successful transurethral resection treatment.
