Retroperitoneoscopic Partial Nephrectomy in a Horseshoe Kidney

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.

Retroperitoneoscopic Partial Nephrectomy for a Horseshoe Kidney Tumor

“…To our knowledge, only four cases of laparoscopic nephron-sparing surgery for tumors in the horseshoe kidney have been published; two of them performed transperitoneally and the other two via a retroperitoneal approach. In this report, we describe the case of retroperitoneal laparoscopic partial nephrectomy for a solid renal mass in the left moiety of a horseshoe kidney 2, 3, 4, 5…”

Laparoscopic heminephrectomy for benign and malignant diseases of the horseshoe kidney

“…Transperitoneal approach has been advocated for laparoscopic radical heminephrectomy and partial nephrectomy for malignant diseases in patients with HK (14,15,(18)(19)(20)(21)27). Conversely, Lee et al suggested retroperitoneal approach for laparoscopic partial nephrectomy in a HK for posterior and posterolateral lesions (26). In the current study, 7 (nonfunctional hydronephrotic and/or infected kidney = 6, kidney mass = 1) and 6 (nonfunctional kidney and/or infected kidney = 6) patients underwent transperitoneal and retroperitoneal laparoscopic heminephrectomy, respectively.…”

Laparoscopic heminephrectomy in horseshoe kidneys: A single center experience

“…have suggested retroperitoneal approach for laparoscopic partial nephrectomy in a HK for posterior and posterolateral lesions. [ 9 ] Researches have reported transperitoneal as well as retroperitoneoscopic approaches for this, but transperitoneal route remains the popular one because of large working space and more familiarity with this approach.…”
