Transcatheter embolization using Gelform pledgets were carried out in 4 patients with kidney cancer before radical nephrectomy. Angiography following embolization revealeda remarkable decrease of renal blood How, which was confirmed by surgical findings as well. Blood loss during surgery was less than 500 ml in the submitted cases except for one in which injury of the ovarian vein led to massive hemorrhage, an preoderpative reduction of tumor vascularity made the surgery technically more expedient. Severe pain on the infarcted kidney region was present in one case, but no other complications were detected. Histological findings of surgical specimens which presented minimum changes were discussed. Reviewing literature it is also indicated that transcatheter embolization promises an effective therapeutic maneuver for the uncontrollable massive hemorrhage and the in situ operation in inoperable cases.
