OBJECTIVE: The use of laparoscopic partial nephrectomy (LPN) in patients with tumours >4 cm remains to be further evaluated. We report our experience with LPN in tumours >4 cm compared with tumours ≤4 cm. MATERIALS AND METHODS: This is a retrospective study of data from all LPN patients operated from 2003 to 2008. Inclusion criteria were a single organ confined contrast enhancing mass/Bosniac III-IV cyst. Hospital admission records were used to extract operative and follow-up data. Patients were grouped into group A: ≤4 cm (32 patients, 53% of total), and group B: >4 cm (28 patients, 47% of total). RESULTS: A total of 60 patients (mean ± SD age, 47.4 ± 13.4 years; M/F, 36/24) were included. Mean ± SD tumour size was 31.5 ± 7.3 mm and 51.6 ± 10.9 mm in groups A and B, respectively. (P < 0.001) Malignant pathology was present in 22 (69%) and 16 patients (57%) in groups A and B, respectively. (P > 0.05) There was no statistically significant difference in age, gender, pre-operative creatinine, estimated glomerular filtration rate (eGFR), and other investigated pre-operative characteristics between study groups. (all P > 0.05) Nor any difference was observed regarding operative and pathologic (warm ischaemia time, operation duration, transfusion, positive margins, and malignant histology) as well as post-operative variables (re-hospitalization, post-operative complications, hospital stay, or eGFR changes). CONCLUSION: The results of this study supports the feasibility and comparability of operative and post-operative early complications for LPN when applied to tumours >4 cm in selected patients compared with tumours ≤4 cm.
