- W2064987641 abstract "Objective: The objective of this study was to compare the outcomes of patients ≥70 years of age undergoing laparoscopic partial nephrectomy (LPN), laparoscopic radical nephrectomy (LRN), and laparoscopic ablative techniques (LAT) for small renal masses. Methods: From a prospectively maintained database we identified 19 (LRN), 28 (LPN), and 19 (LAT) patients aged ≥70 who underwent surgery for cT1aN0M0 lesions. Perioperative, surgical, and functional outcomes were compared. Results: The three groups were similar in age, race, body mass index, and estimated creatinine clearance. In the LRN group, mean tumor diameter was larger (3.3 vs. 2.4 cm [LPN] and 2.7 cm [LAT]; p = 0.0005) and there was a higher percentage of central tumors (73.7% vs. 25.0% and 5.3%; p < 0.0005) when compared with the LPN and LAT groups, respectively. Although intraoperative and postoperative complication rates were similar, mean estimated blood loss and operative time were highest in the LPN group (p < 0.05). Moreover, 42.1%, 39.3%, and 42.1% of patients had preoperative stage 3 chronic kidney disease in the LRN, LPN, and LAT groups, respectively. Patients who underwent LRN had a lower follow-up estimated creatinine clearance (43.4 vs. 61.4 mL/min [LPN] and 59.2 [LAT]; p < 0.01) and a higher likelihood of developing stage 3 chronic kidney disease after treatment (100% vs. 25.0% [LPN] vs. 18.2 [LAT]; p < 0.0005). Conclusions: Impaired renal function is common in elderly patients presenting with renal masses. LPN and LAT provide superior preservation of renal function when compared with LRN in this population. In appropriately selected patients ≥70 years of age presenting with T1a renal lesions, laparoscopic nephron-sparing approaches should be considered." @default.
