[Resection syndrome following transurethral resection of the prostate].

The essence and clinical aspects of the resection syndrome occurring in association with transuretheral prostate resection and the possiblity of determining the direction of the absorption of the washing solution are discussed. By means of radioisotope tests a direct correlation was detected between the extent of the haemorrhage and the intravasation of the washing solution. Great importance is ascribed to the vesico-renal reflux often occurring during resection, which might have a major role in the development of post-resectional pyelonephritis.
