“…In fact, performance of laparoscopic partial nephrectomy for a renal mass has only been reported in seven patients with HSK. [7][8][9] The tumors ranged from 2 to 6.9 cm in diameter, WIT was 11-31 min, and estimated blood loss was 70-490 mL. Major complications were not reported in these patients.…”

“…Several anatomical features of HSK make laparoscopic partial nephrectomy challenging, including variability of the blood supply, limited mobilization of the fused kidney, and abnormal anatomy of the kidneys and adjacent structures.

The tumors ranged from 2 to 6.9 cm in diameter, WIT was 11–31 min, and estimated blood loss was 70–490 mL.…”

Robot‐assisted laparoscopic partial nephrectomy for horseshoe kidney: A case report

Introduction Horseshoe kidney has unique anatomical features, such as a complex blood supply. We report a patient with renal cell carcinoma in a horseshoe kidney, who underwent tumor resection by robot‐assisted laparoscopic partial nephrectomy based on preoperative three‐dimensional computed tomography. Case presentation A 66‐year‐old man was referred to our hospital with a 2‐cm enhancing mid‐pole mass in the left moiety of a horseshoe kidney. The clinical diagnosis was renal cell carcinoma cT1aN0M0 (R.E.N.A.L. nephrometry score: 1 + 2 + 3 + 3 = 9p). Robot‐assisted laparoscopic partial nephrectomy was performed with selective clamping based on reconstructed three‐dimensional images. The warm ischemia time was 13 min. Pathologic examination confirmed a diagnosis of pT1a clear cell renal cell carcinoma with negative surgical margins. At 6 months postoperatively, computed tomography showed no local recurrence or metastasis and renal function was intact. Conclusion Robot‐assisted laparoscopic partial nephrectomy with preoperative three‐dimensional computed tomography may have advantages for resection of tumors in patients with horseshoe kidney.

“…Horseshoe kidney is a congenital benign malformation present in the population at a rate of 0.15–0.25% and is characterized by anatomical abnormalities such as ectopia, malformation and vascular changes 1 . The incidence of renal cell carcinoma in horseshoe kidneys is estimated to equal that in normal kidneys.…”

Horseshoe kidney is one of the most common congenital renal fusion anomalies and the incidence of renal cell carcinoma in horseshoe kidney is predicted to be approximately 5.2/100000 individuals. Because horseshoe kidney merges malformations and vascular changes, open surgery is the standard for treatment. There are no reports of robot-assisted partial nephrectomy (RAPN) for renal cell carcinoma in horseshoe kidney. We describe for the first time the safety and the utility of RAPN in a horseshoe kidney with renal cell carcinoma.

Laparoscopic nephron-sparing surgery for a tumor near the isthmus of a horseshoe kidney with a complicated blood supply

A horseshoe kidney is a congenital kidney malformation commonly associated with complications such as hydronephrosis, renal calculi, and infections of the renal pelvis. Renal cell carcinoma is extremely rare in a horseshoe kidney; once it occurs, however, it is intractable because of vascular abnormalities. This is especially true in laparoscopic nephron-sparing surgery, even for tumors of <4 cm in diameter. We herein report a case involving an asymptomatic 65-year-old man with an incidental finding of a 4-cm solid mass near the isthmus of a horseshoe kidney on B-mode ultrasonography. Preoperative computed tomography of the renal artery revealed six arterial vessels supplying the affected kidney. Laparoscopic partial nephrectomy was performed. The outcome of this case suggests that laparoscopic nephron-sparing surgery might be a successful treatment method for a horseshoe kidney but that preoperative vessel evaluation and experienced laparoscopic skills are needed.
