Abstract
Data from 120 patients diagnosed as having renal cell carcinoma (RCC), and treated in an organpreserving surgical manner were analyzed from 11 participating Austrian urological centers. The male to female ratio was 66:54. The subjects age ranged from 27 to 75 years with mean age of 59 years. The indication for conservative tissue-saving surgery was a solitary kidney in 48 instances, a bilateral RCC in 18 cases and, in 2 patients, a horseshoe kidney tumor. In 52 cases the indication for conservative surgery was a peripheral, easily resectable, low-stage tumor (elective indication). Results were comparable to radical nephrectomy of low-stage tumors especially relating to survival rates. Ninety-nine patients survived and were tumor free at the point of check up (December 1988). Thirteen patients had either local tumor recurrence and/or métastasés and 5 patients died from the disease. The operative mortality and the morbidity rate was very low.
