[Laparoscopic radical nephrectomy: indications, techniques, and oncological outcome].
Renal cell carcinoma is likely to become one of the most important indications for laparoscopic surgery worldwide. The laparoscopic technique combines the benefits of the minimally invasive approach with established surgical principles. In our institution the laparoscopic transperitoneal approach with intact specimen extraction has become the standard technique for radical nephrectomies. We report the indications, techniques, and oncological outcome in a single center experience in 100 cases. The mean tumor size was 5.9 cm (range: 2-11 cm), the blood loss was 220 ml, and the mean surgical time was 211 min, including the learning curves of five surgeons. Histological findings were pT1 in 66 (66%), pT2 in 11 (11%), and pT3 in 19 (19%) patients with an increasing tumor size according to the experience of the surgeons. In four cases (4%) histology did not prove malignant disease. Positive lymph nodes were detected in three cases (3%) and surgical margins were negative for tumor in all patients. To date 61 patients were available for follow-up; patients with primary metastatic disease were excluded from this analysis. Follow-up was between 1 and 30 months with an average of 12.9 months. Progressive disease occurred in two cases in patients with pT3G3 tumors. No cases of local recurrence or port metastasis occurred during observation. Laparoscopic radical nephrectomy is a routine, effective treatment for patients with renal cell carcinoma. Our follow-up data up to 30 months confirm the effectiveness of laparoscopic radical nephrectomy in terms of surgical principles and oncological outcome.
