Abstract

Introduction: Laparoscopy allows minimally invasive approaches for procedures traditionally performed openly, with associated lower morbidity. Nephron-sparing surgery (NSS) is mostly regarded as an open procedure because laparoscopic partial nephrectomy (LPN) is technically challenging. We evaluated our centre's experience with LPN and open partial nephrectomy (OPN). Methods: All patients over five years (2005–2010) undergoing NSS were identified retrospectively from our operating room management information system. Case notes, diagnostic and post-operative surveillance imaging were reviewed. Post-operative morbidity, histopathology and serum full blood count and urea and electrolyte reports were recorded. Results: A total of 97 OPNs and 23 LPNs were performed. Median length of stay was six days for OPNs and three days for LPNs (p= 0.005). Mean drop in haemoglobin (Hb) was 2.6 g/dl for both OPNs and LPNs. No significant difference in transfusion rates was observed. Median warm ischaemia time (WIT) for OPNs was 14 minutes and 32 minutes for LPNs (p < 0.0001). No significant difference was seen in changes from baseline serum creatinine when comparing OPNs with LPNs at day 1 (p = 0.7572) and at 12 months (p = 0.7406) post-operatively. Surgical margins were positive in 20 (21.5%) OPNs and negative in all LPNs (p = 0.038). One patient developed local recurrence following OPN (clear margins) and two patients developed distant metastases. Conclusions: Benefits of LPN include shorter hospital stay and satisfactory long-term preservation of renal function, despite longer WITs. This demonstrates the benefits of LPNs in patients with single exophytic renal tumours performed by highly experienced, regionally selected laparoscopists.
