Transabdominal and lumbar nephrectomy for renal adenocarcinoma

The results of 178 transabdominal and 79 lumbal nephrectomies were compared, based on a consecutive series of patients with renal adenocarcinoma. The corrected 5-year survival rate for patients without distant metastases was 64% for transabdominal and 57% for lumbar nephrectomy. This difference is not statistically significant. The transabdominal approach made possible a more extensive operation in patients with tumours extending to neighbouring organs, but none has survived as long as three years. Duration of surgery, need for blood transfusion and duration of postoperative hospital care were similar. Splenic injury occurred in 9.6% of the patients with transabdominal nephrectomy, but this did not result in additional morbidity or mortality. There were a few other sporadic complications.
