Materials and methods: We evaluated the data of 63 patients who had undergone LPN (n=32) or OPN (n=31) for renal tumors with a RENAL nephrometry score of ≥7 between 2016 and 2022, retrospectively. We compared the preoperative, functional and oncological outcomes among the groups. The warm ischemia time (WIT) of <25 minutes, no surgical complications and negative surgical margins were defined as trifecta.
Results: No differences in the diameter of the tumor (4.15±1.28cm, 5.62±2.84cm, p=0.552), in the pathological stage and the median RENAL nephrometry score (8.00 [7-10], 8 [7-11], p=0.257) were observed between the OPN and the LPN groups. There were no differences regarding the trifecta outcomes, the operative time, the estimated blood loss, WIT, the complication rates, and the length of hospital stay among the groups. The percentage decrease in glomerular filtration rate at the early and the last follow-up were similar. The mean follow-ups after LPN and OPN were similar (13.69±7.46 months, 18.68±12.28 months, p=0.55, respectively).
Conclusions: The laparoscopic approach has a similar protection of renal function without compromising functional and oncological results in comparison with OPN for anatomically complex renal tumors. Therefore, laparoscopic approach is also safe with partial nephrectomy for complex renal tumors.}, number={1}, publisher={Pamukkale Üniversitesi}
