“…The horseshoe kidney consists of two different functional kidneys on each side of the medial line of the body, which are connected to the lower poles by the isthmus. Isthmus contains blood vessels, functional tissue of the renal parenchyma, or connective tissue [4,5]. Cheminephrectomy is indicated for localization of tumors in the central part of the kidney, for tumors of larger dimensions, tumors in unfavorable position to the pyelocalyx system and vascular stem, in cases of thicker and highly vascularized isthmus as well as in elderly patients.…”

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.

Introduction: Colorectal cancer is a very common malignancy, however the association with kidney cancer is very unusual, even more so if kidney cancer occurs on a horseshoe kidney. Horseshoe kidney is a congenital malformation in which the kidneys appear fused. It is often accompanied by abnormalities of the ureteropelvic and vascular systems, so patients in need of surgery should be carefully evaluated. Materials and Methods: A 64-year-old woman came to our observation with abnormalities of the perineum such as the "vestibular anus", horseshoe kidney, kidney cancer and colorectal cancer. She underwent left open hemicolectomy and right polar resection of the horseshoe kidney. Results: The patient was discharged on the sixth operating day without complications. At the follow-up 54 months after surgery, she was negative for distant metastasis and local disease recovery. Conclusion: From a literature review this is the first case report in a patient with these four associated comorbidities. Preoperative evaluation in these patients by CT is important to evaluate the relation between the nervous, vascular and urinary structures to avoid iatrogenic injury.

“…Due to accompanying anatomical disorders, one-third of patients have renal stones or hydronephrosis due to stricture of the ureteropelvic junction [ 5 , 6 ]. No association has been noted between horseshoe kidney and renal cell carcinoma, and only 200 cases have been published [ 7 ].…”

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.
