Abstract

A 21-year-old woman with a 4 cm enhancing cystic renal mass in the left moiety of a horseshoe kidney was treated through a retroperitoneal laparoscopic approach. The tumor was excised completely with cold scissors, and renal parenchyma suturing with a surgical bolster was done with Vicryl 2-0 sutures. Choosing the proper approach according to the location of the lesion and the surgeon's experience with both approaches are of importance in laparoscopic surgery in horseshoe kidney cases. A preoperative kidney computed tomography angiography was helpful for understanding the complex renal vasculature.

• 

  FIG. 1 Horseshoe kidney with 4 cm cystic mass in the posterior aspect of the left moiety (A, B) with a small artery arising from the left common iliac artery feeding the isthmus in computed tomography angiography (C, D).

• 

  FIG. 2 The position of port placement in retroperitoneoscopic partial nephrectomy.

• 

  FIG. 3 Tumor site (white circle) located on the left moiety adjacent to the isthmus (white arrow) (A), excision of tumor (B), tumor excision site (C), and sutured excision site (D).

• 

  FIG. 4 No perfusion decrease was observed in the left kidney on a computed tomography scan 5 months after the operation (A, B).
