Unilateral Synchronous Multiple Kidney Tumors Managed by Laparoscopic Partial Nephrectomy: Five-year Follow-up

Abstract

Unilateral synchronous multifocal renal tumors are rare. Due to the limited data in the literature and challenges in the technique, there is still doubt on the application of laparoscopic partial nephrectomy (LPN) for the management of such tumors. Herein, we report a 36-year male patient presenting with right-sided flank pain and microscopic hematuria. Abdominal computed tomography (CT) revealed five solid masses, the largest of which was 27 x 18 mm. The patient underwent LPN and the largest mass was resected with the control of segmental artery of the lower pole of the right kidney. The remaining four masses were resected by zero-ischemia technique. Final pathology revealed renal cell carcinoma in all masses. Postoperative period was uneventful. No recurrence was detected during a 5-year follow-up.

Retroperitoneal laparoscopic partial nephrectomy for unilateral synchronous multifocal renal carcinoma with different pathological types: A case report

“…PN is relatively difficult for multiple lesion resection and renal reconstruction. For unilateral multifocal renal tumors, laparoscopic partial nephrectomy (LPN) has been proven safe and feasible with acceptable oncological results and complication rates in selected patients[ 6 , 7 ]. For USMRC cT1 stage, PN can prevent unnecessary renal unit damage and achieve the same effect as RN, and postoperative quality of life in patients is better[ 8 - 10 ].…”
