[Operative complications in transurethral operations: causes and prevention].

Complications resulting from transurethral operations can be classified as intraoperative, directly postoperative and late complications. Specific problems are related to prostatic resection, resection of bladder tumors or lithotripsy of bladder stones. An analysis of these problems is presented based on in the experience in more than 10 000 transurethral operations. Directives are developed to avoid additional intraoperative harm and minimize resulting problems. Methods for correction of iatrogenic complications are explained.
