Horseshoe kidney has an incidence rate ranging from 1 in 400 to 1 in 1000, with a 2:1 ratio in men. It also has a predilection for chromosomal aneuploidies. From a pathophysiology standpoint, this anomaly occurs during the second to sixth week of gestation when the inferior portion of the metanephric blastema fuses to form an isthmus, commonly in the lower renal pole (90%). As a result of this fusion, the kidney may not bypass the inferior mesenteric artery and is impeded in its ascent. With an aberrant anatomical orientation and location, complications arise including hydronephrosis, renal calculi and a twofold risk of Wilms tumour. Despite these findings, the association of renal cell carcinoma (RCC) within a horseshoe kidney is extremely rare and fewer than 200 cases have been described. Therapeutically speaking, partial nephrectomies are the gold standard of treatment for renal tumours smaller than 4 cm in diameter, with a growing indication to accomplish this procedure by laparoscopic or robotic means. We report a case of an asymptomatic 58-year-old male with an incidental computed tomography scan finding of a 4-cm solid mass in the right moiety of a horseshoe kidney. He was treated by laparoscopic partial nephrectomy. There have only been 2 other reported cases to our knowledge on a laparoscopic partial nephrectomy in a horseshoe kidney for RCC. We believe that, in experienced hands, the laparoscopic approach may be used successfully for this clinical situation.

Introduction. Horseshoe kidney is one of the most common congenital renal fusion anomalies. Due to its poor mobility and abnormal vasculature form, surgeons should pay close attention to all anatomical variations. Case Presentation. An 83-year-old woman was referred to our hospital because of left renal tumor in a horseshoe kidney incidentally found by her previous hospital. We performed laparoscopic partial nephrectomy. The pathological diagnosis was clear cell renal cell carcinoma. G2 INFα V-pT1a with a negative surgical margin. No evidence of recurrence has been noted, and the renal function is well preserved at 28 months after surgery. Conclusion. When performing laparoscopic partial nephrectomy for renal carcinoma, especially a horseshoe kidney, preoperative imaging is crucial for identifying the location of the renal vessels.

Introduction. Horseshoe kidney is the most common developmental disorder of the urinary system, which involves an anomaly of kidney fusion, and occurs in 3% of the population. Kidneys are most often connected at the lower poles by fibrous or parenchymal isthmus. Renal cell carcinoma (RCC) is the most common tumor of the horseshoe kidney. Treatment involves surgical treatment that includes heminephrectomy or partial nephrectomy with different approaches. We report a case of RCC of a horseshoe kidney, located on lower pole and isthmus. Case outline. A sixty-eight-year-old patient reported to the urologist due to intermittent painless macroscopic hematuria. CT urography revealed the presence of a tumor on the right kidney measuring 85 ? 90 ? 60 mm, with radiological characteristics of RCC, which covered the entire lower pole of the kidney towards the isthmus. Angiography finding indicated thickened isthmus with pronounced malformation of vascular structures. The right heminephrectomy was performed with resection of the isthmus from 15 mm to healthy tissue. The isthmus was sutured in two layers with a catgut suture. Subsequently, hilar, paracaval, and interaorthocaval lymphadenectomy were performed. The pathohistological finding indicated a tumor of renal cell origin while the resection line was free of tumor tissue, as were the lymph nodes Conclusion. RCC is the most common neoplasm of the horseshoe kidney. Treatment is surgical and involves open or laparoscopic heminephrectomy or partial nephrectomy with a transperitoneal or extraperitoneal approach.

Horseshoe kidney (HSK) is a benign malformation characterized by three anatomic abnormalities: ectopia, malrotation, and vascular changes.1 Renal cell carcinoma (RCC) comprises approximately 53.8% of HSK malignancies. The incidence of RCC within HSK is predicted to equal that within the general population, approximately 5.2/100 000 individuals.2-4 Surgical resection of these tumors has been described in the literature. Evidence is mounting that partial nephrectomy, rather than radical nephrectomy, and minimally invasive techniques for T3a RCC is safe and attains equivalent oncologic outcomes.5,6 Review of the literature reveals no case reports of laparoscopic partial nephrectomy for T3a RCC, and therefore, this is the first report of a laparoscopic partial nephrectomy of T3a RCC HSK with renal vein tumour thrombus.
