Gasless laparoscopy-assisted nephrectomy without tissue morcellation for renal carcinoma.

Abstract

The efficacy of gasless laparoscopy-assisted nephrectomy for renal tumors is determined. Seven patients with renal tumors underwent gasless laparoscopy-assisted nephrectomy. The results were compared to those of patients undergoing open nephrectomy. 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. 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.
