Abstract
BackgroundLaparoscopic partial nephrectomy (LPN) is on the rise as an alternative minimally invasive technique to open partial nephrectomy (OPN), especially in patients with stage1 tumors. Patient and methodsA 49-year-old man had a past history of bilateral renal lithiasis managed with extracorporeal lithotripsy. Urotomography study identified a renal tumor that was dependent on the upper pole of the right kidney; when enhanced in the arterial phase it was approximately 3×4cm in size with 20Hounsfield units. ResultsPhysical examination revealed a soft, flat abdomen with normal peristaltic noises that was painless upon palpation; no abdominal organomegaly was palpated. Laboratory test results were: Hb 15; Hct 44%; leukocytes 13.2, platelets 171; glucose 120; BUN 8.7; creatinine: 1.12; albumin 4.5; LDH 141; alkaline phosphatase 103; TB 0.6; IB 0.5; DB 0.1; PT 13.1; and PTT 28.8.Laparoscopic partial nephrectomy was performed revealing the anatomic variant of 2 renal arteries, a right 5×4cm renal tumor dependent on the upper pole, warm ischemia time of 28min, 200mL intraoperative blood loss, and surgery duration of 2h.
