摘要
Operative method, course and complications were analyzed retrospectively in 140 patients who underwent a conservative operation for renal tumor between June 1969 and December 1990. In 53 patients (20 women and 33 men, mean age 61.2 years, range 38 to 77 years, with 49 renal cell carcinomas and 4 benign renal tumors) there was an imperative indication for an organ preserving operation because nephrectomy would have made dialysis obligatory. In 87 patients (29 women and 58 men, mean age 53.7 years, range 27 to 74 years, with 72 renal cell carcinomas and 15 benign renal tumors) the tumor was conservatively resected in the presence of a normal contralateral unit (elective indication) and 68 of these patients (78%) were symptom-free. In the imperative group 32 of 49 patients (65.3%) with renal cell carcinoma had no evidence of disease after a mean followup of 4.6 years. Known metastases were present in 4 of 7 patients who died of the tumors in this group. In 3 patients with an imperative indication for conservative surgery a second tumor occurred in the kidney: 2 were treated with further parenchyma sparing operations, while in 1 with poor physical condition no further measures were possible. Of 72 patients with renal cell carcinoma who underwent an elective operation 68 (94.4%) had no signs of tumor progression after a mean followup of 3.3 years. One patient died of tumor metastases, and 2 (2.7%) had tumor recurrence in the kidney requiring nephrectomy and enucleation, respectively. The 5-year cause-specific survival rates for the imperative and elective groups were 84% and 96%, respectively. Patients with a local stage T3 tumor were characterized by a significantly worse survival curve than those with a stage T1 or T2 tumor but no significant difference was noted among the various grades of differentiation.
