“…Most case reports of CFRE were found incidentally. Treatment is only indicated when symptoms in the upper urinary tract are significant-most frequently these include nephrolithiasis and vesicoureteral reflux [11]. If an ectopic kidney is found to be nonfunctioning, then surgical excision may be necessary [12].…”

Case Report of a Pelvic Crossed Fused Renal Ectopic Kidney

Herein we present a case of a horseshoe kidney with crossed fused renal ectopia. Both of these pathologies are congenital anomalies; however, to date, there are few cases that present with both. In this case, discovered during routine dissection, the fused kidney was mostly left-sided and very low in the pelvis. No renal artery arose from the right wall of the abdominal aorta, and the right renal vein drained into the lower part of the inferior vena cava (IVC) where the right and left common iliac veins joined. It is essential for clinicians and surgeons to understand these types of congenital anomalies, as they could impact patient care.

“…However, to date, there are no specific guidelines for the management of CFRE. It is important for clinicians to know that the fused kidneys do not need to be separated unless symptoms are present [11]. CFRE can occasionally be palpated as abnormal abdominal masses [7].…”

“…Left to right crossover occurs more frequently than its counterpart and kidneys are fused together in roughly 90% of cases. 1,2 Crossed fused ectopia is the most common fusion anomaly after horseshoe kidneys, detected in only 1:2000 autopsies with a slight male predominance (3:2). This entity is thought to result from the abnormal development and migration of the ureteric bud and metanephric blastema at 4-8 weeks of gestation.…”

“…This entity is thought to result from the abnormal development and migration of the ureteric bud and metanephric blastema at 4-8 weeks of gestation. 2 Crossed fused ectopia is divided into six subgroups based on the degree of fusion, location and rotation of the fused renal mass. 1,2 Most commonly, the crossed ectopic kidney is inferior to the normally positioned kidney as in this case.…”

Crossed renal ectopia with fusion is an extremely rare congenital anomaly with few reported cases of pelviureteric junction obstruction, which often involves the crossed-over kidney. To our knowledge, we describe the second case in literature to report an uncrossed kidney with pelviureteric junction obstruction and giant hydronephrosis, which obstructs the pelviureteric junction of the crossed-over kidney. The grossly hydronephrotic kidney was found to be poorly functioning and an aberrant crossing vessel was considered to be potentially involved, raising both diagnostic and management challenges. By reporting this case, we aim to stress the importance of adequate mapping collecting systems, drainage patterns and vascular supply in such crossed fused anomalies.

“…1 This condition is thought to be secondary to abnormal migration of the ureteric buds. 2,3 The most prevalent anatomic pattern is that in which the ectopic kidney crosses the midline and lies below the normal kidney: the ectopic renal ureter usually crosses the midline and inserts itself over the normal anatomic position. This increases the risk of injury during open surgery.…”

Case ReportAn 88-year-old man with an expanding, asymptomatic infrarenal AAA was referred to our institution. A computed tomogram (CT) showed a 5-cm maximal diameter of the AAA (Fig. 1). The AAA had a 25-mm-long infrarenal neck that was 23 mm in diameter proximally and 25 mm distally. The patient had a crossed-over ectopic right kidney fused with the left kidney; the ectopic RA arose directly from the AAA and was 5.3 mm in diameter. The distal aortic neck was 25 mm in diameter, and the diameters of the common iliac arteries were 11 mm (left) and 9.7 mm (right).The patient's medical history included hypertension, type 2 diabetes mellitus, obstructive sleep apnea, and hyperlipidemia. He had also undergone multiple operations, including a transurethral prostatectomy, an exploratory laparotomy for trauma, and ventral hernia repair with use of mesh. His renal function was normal (serum creatinine level, 0.95 mg/dL; and estimated glomerular filtration rate, 75 mL/min). He was at high risk for surgery because of his comorbidities, hostile abdomen, and crossed fused ectopic kidney, so we recommended endovascular aneurysm repair (EVAR) of the AAA. We intended to preserve the ectopic RA by using the chimney technique, also called the parallel stent-grafting or snorkel technique.After we attained percutaneous access to both common femoral arteries by means of ultrasonographic guidance, we inserted 6F sheaths bilaterally. We introduced a 5F pigtail catheter into the abdominal aorta. An abdominal aortogram of the infrarenal AAA showed the ectopic right RA originating from the AAA (Fig. 2). We decided to perform EVAR with the parallel endograft oriented caudally, because the distance would be shorter and the angle less acute than if the graft were directed proximally. We then pre-closed the femoral arteries with use of a 10F Prostar ® XL vascular closure device (Abbott Vascular; Redwood City, Calif ). We inserted one 20F Gore ® DrySeal sheath (W.L. Gore & Associates, Inc.; Flagstaff, Ariz) for subsequent placement of the main endograft device through the left femoral artery, and another for snorkel and limb extension through the right femoral artery.We selectively cannulated the accessory RA with use of a 5F Renal Double Curve catheter (Cordis Corporation, a Johnson & Johnson company; Miami Lakes, Fla) and a 0.018-in Hi-Torque Steelcore Peripheral Guide Wire (Abbott Vascular).
