Objective
With increasing surgeon experience, the use of laparoscopic radical nephrectomy (LRN) in large and locally advanced renal tumours (T3a) is gaining favour in urological practice. There are limited studies reporting surgical outcomes in such groups. The aim of this study was to review our experience with LRN in these patients.
Methods
Data was retrospectively collected on 201 consecutive patients who underwent LRN for renal cancer by a single surgeon. Perioperative parameters assessed were age, gender, American Society of Anaesthesiologists score (ASA), waist circumference, tumour size, specimen size, histological subtypes, anaesthetic duration, operative approach and technique, surgery duration, blood loss, pre and postoperative renal function, complication rate and duration of hospital stay.
Results
Of 201 patients undergoing LRN, 43 (21%) patients had T3a tumours (group 2). The remaining 158 (79%) patients had T1 tumours (group1). Mean tumour size in group 2 was 12.2 cm. Renal cell carcinoma (RCC) was more common in males than females (131/201; 65%). Patients with T3a disease were more likely to have an ASA score of 2 (37/201; 18%). In the majority of patients across both groups, LRN was completed using a 3-port approach (173/201; 86%). There were no significant differences between groups in terms of mean anaesthetic duration, average surgical time, average estimated blood loss, complication rate and mean hospital stay.
Conclusion
Our study shows that LRN has equivalent perioperative outcomes and safety in larger and locally advanced renal tumours.
