PURPOSE: The efficacy of gasless laparoscopy-assisted nephrectomy for renal tumors is determined. MATERIALS AND METHODS: Seven patients with renal tumors underwent gasless laparoscopy-assisted nephrectomy. The results were compared to those of patients undergoing open nephrectomy. RESULTS: Although a long operating time was required, convalescence was significantly more rapid. En bloc removal of the kidney and complete pathological examination were possible in all patients. CONCLUSIONS: This procedure may be useful for the treatment of noninvasive renal carcinoma, especially in patients with cardiovascular and/or ventilatory complications. However, long-term followup is necessary to confirm the efficacy in preventing recurrence.
