Abstract:

Objective: Surgery is the gold standard therapy method in renal tumors. Renal tumor surgery can be performed as open radical nephrectomy, open partial nephrectomy, laparoscopic radical nephrectomy or laparoscopic partial nephrectomy.Each technique has its own advantages and disadvantages. In this research, it was aimed to evaluate the renal tumor surgery techniques in our clinic and the oncological data obtained from the patients. Material and Method: A total of 92 patients with a radiologically proven renal mass were underwent surgery between July 2011 and January 2018. The clinical, oncological and pathological results of these patients are evaluated according to their surgical approach retrospectively. The obtained data were evaluated according to the surgical technique. Results: The patients who have renal mass underwent partial nephrectomy (n:39), radical nephrectomy (n:38), laparoscopic radical nephrectomy (n:14) and laparoscopic partial nephrectomy (n:1). The most common pathological tumor type is clear cell carcinoma (n: 56), the most common T stage is T1b (n: 39) and the most common tumor grade is Fuhrman grade 2 (n:34). The average tumor mass size of open partial nephrectomy patients are 3.3±1.8 cm, significantly smaller than the radical surgeries (p<0.05). In laparoscopic cases, peroperative bleeding volume and postoperative hospitalization time is lower than the open surgeries (p<0,05). By the means of follow up of the patients, only 3 patients have tumor recurrence and there is no significant difference between open, laparoscopic or partial surgeries (p>0,05). Surgery is still the best type of oncological treatment in kidney tumors. Partial and laparoscopic radical nephrectomy has similar oncologic results with open radical nephrectomy in selected cases. Kidney tumor surgery results in our clinic have similar characteristics with the literature.
