ABSTRACT

Conclusion:

Laparoscopic partial nephrectomy for renal tumors is an effective and feasible procedure with acceptable oncologic results. However, tranfusion rate and requiremet of pelvicaliceal system repair were more common in patients with tumor >4 cm.

Results:

The mean age of the patients was 59.2±10.9 (range: 26-81) years. The mean tumor size and the mean RENAL nephrometry score were significantly higher in group 2 than in group 1. The mean operation time and warm ischemia time were similar between groups but estimated blood loss and transfusion requirement were significantly higher in group 2. Convertion to open surgery was seen two patients in group 2 and one patient in group 1. Only one patient underwent radical nephrectomy for uncontrolled bleeding in group 2. There was no difference in preoperative and 3-month postoperative serum creatinine levels between the groups. The incidence of positive surgical margin was 0% and 5% in group 1 and group 2, respectively.

Methods:

We retrospectivelly evaluated the medical records of 65 patients who underwent laparascopic partial nephrectomy between May 2009 and June 2013 in our clinic. The patients were divided into two groups according to tumor size. Patients with a tumor <4 cm and >4 cm were included in group 1 (n=45) and group 2 (n=20), respectively. Demographic, perioperative and postoperative parameters were compared between the groups. Histopathological examination and surgical margin status were also evaluated.

Aim:

To evaluate safety and efficiency of laparoscopic partial nephrectomy for renal tumors larger than 4 cm.
