Abstract

OBJECTIVES:

Renal cell carcinoma (RCC) is likely to become one of the most important indications for laparoscopic surgery. We herein report our experience.

METHODS:

From April 1994 until April 1999, 98 patients presenting with RCC were treated laparoscopically by either radical nephrectomy (RN; n = 73) or wedge resection (WR; n = 25). The mean age was 62.3 years. The mean tumour diameters were 3.8 cm (RN) and 1.9 cm (WR). All tumours were clinical stage T1 lesions. The transperitoneal approach was used for RN in all patients. For WR either the transperitoneal or the retroperitoneal approach was used. In 15 patients, the adrenal gland was removed simultaneously. The specimen was entrapped in an organ bag and removed intact through a small muscle-splitting incision in the lower abdominal wall.

RESULTS:

RN: The mean operating time was 142 (range 86-230) min, the mean blood loss was 170 (range 0-1,500) ml, and the mean postoperative hospital stay was 7.4 (range 3-32) days. Minor complications occurred in 4.0% of the patients, while major complications were seen in 8.0% of them. WR: The mean operating time was 163.5 (range 90-300) min, the mean blood loss was 287 (range 20-800) ml, and the postoperative hospital stay was 8.0 (range 3-8) days. Minor complications: 4%, major complications: 8%. Histology revealed RCC stage T1 in 77 patients, stage T3a in 7, and stage T3b in 3 patients, oncocytoma in 2 patients, angiomyolipoma in 2, renal adenoma in 1, renal metastasis in 1, multilocular cysts in 4, and renal abscess in 1 patient. Over mean follow-up periods of 13.3 and 22.2 months for RN and WR, respectively, neither local recurrences nor metastases have been observed among patients with histologically confirmed RCC.

CONCLUSIONS:

Laparoscopic surgery for clinical stage T1 RCC is safe and efficient. Excellent tumour control can be achieved. However, longer follow-up periods will be necessary to confirm these results.
