Objective: To evaluate the modified Makuuchi incision in the surgical treatment of renal tumors. Material and methods: A total of 29 patients with renal tumors were operated using the modified Makuu - chi incision. Patients’ age ranged from 48 to 72 years. Twenty-three patients were male, and 6 patients were female. Renal tumors affected the right side in 22 patients and the left side in 7 patients. Twenty-six patients underwent radical nephrectomy, while 3 patients underwent partial nephrectomy. Results: A perfect exposure was achieved with this incision in the surgical field. No serious complica - tions such as bleeding or other organ injuries happened during the surgery. Blood transfusion during surgery was unnecessary. Additional use of analgesics due to wound pain during the postoperative period was not required. Incision-related complications, such as wound infection and wound dehiscence, did not occur in the early postoperative period. Patients had no complaints about the cosmetic appearance of their abdomen due to the incision. Incisional hernia was not observed in patients. Conclusion: This type of incision provided a perfect exposure of the field in the surgical treatment of renal tumors
