Nefrectomía parcial laparoscópica. Análisis de los primeros 30 casos de nuestra serie y revisión de la literatura

Abstract

Objective: Our goal is to analyze the surgical and clinicopathological results of our first 30 laparoscopic partial nephrectomies (LPN) performed consecutively and correlate the results with the literature. Material and methods: This is a cases series, with 30 patients (20 men and 10 women) operated between 2006 and 2008. We assessed the clinicopathological factors and complications. The mean and median follow-up was 25 and 5 months. Results: Resected tumors had an average size of 2.4 cm. 60% of the tumors were malignant. The pathological stage was pT1 in 100% of cases (47% grade I, 53% Fuhrman grade II). Surgical margins were positive in 3 cases, switching to open surgery. Intraoperative bleeding was 74.66 cc (35.7±SD) and 70 cc of mean and median. The mean operative time was 214.4min (±69) and ischemia time of 31.3min (±13.8). Conclusions: Our results are similar to those reported in the literature, except for positive margins and conversion attributable to the learning curve.
