The authors report the first case series of conventional laparoscopic partial nephrectomy in Thailand. Laparoscopic partial nephrectomy was successfully performed in two patients with small renal tumors. The first patient underwent transperitoneal laparoscopic partial nephrectomy for a 3.8 x 3.3 cm renal mass. Intraoperative blood loss was 100 ml with warm ischemic time of 38 minutes. Pathological report showed renal cell carcinoma. The patient proceeded with laparoscopic radical nephrectomy, as surgical margin was not free. The second patient underwent retroperitoneal laparoscopic partial nephrectomy for a 1.8 x 2.4 cm renal mass. Intra-operative blood loss was 200 ml with clamping time of 45 minutes. Pathological report showed angiomylipoma. Using two different approaches of laparoscopy, namely, transperitoneal and retroperitoneal approaches, patients gained benefit from small incision and fast recovery.
