Core Tip

Core Tip: Unilateral synchronous multifocal renal carcinoma (USMRC) is defined as having more than two malignant tumors with a spacing ≥ 1 cm in one kidney. USMRC is rarely reported and nephron-sparing surgery for USMRC is difficult. We describe a patient with USMRC who underwent retroperitoneal laparoscopic partial nephrectomy (RLPN). There were no complications peri-operatively. Histopathology revealed clear cell renal cell carcinoma at the lower pole of the right kidney and chromophobe renal cell carcinoma at the middle dorsal portion of the right kidney. No tumor bed recurrence or metastasis was observed on imaging and his renal function remained stable during the 12-mo follow-up. Thus, RLPN is safe, effective, and feasible for the management of USMRC.
