ABSTRACT
Se presenta el caso clínico de un adolescente de 14 años de edad, blanco, quien acudió al Centro de Salud Urbano Satelital de la amazonía ecuatoriana de Tena por presentar dolor mantenido de moderada intensidad en flanco derecho con irradiación al muslo del mismo lado. Se le realizó ecografía abdominal, que indicó la existencia de un riñón en herradura y posible agenesia de este órgano en el lado derecho, por lo cual se decidió efectuar un urograma excretor, cuyos resultados mostraron una ectopia renal cruzada izquierda. El paciente inició tratamiento profiláctico con seguimiento trimestral y tuvo una evolución favorable.
The case report of a 14 years white adolescent, who went to the Satelital Urban Health Center of Tena Ecuadorian amazonía is presented due to a sustained pain of moderate intensity in the right flank with irradiation to the thigh of the same side. An abdominal ultrasound was carried out that indicated the existence of a horseshoe kidney and possible agenesis of this organ in the right side, reason why it was decided to make an excretor urogram whose resulting in a left crossed renal ectopia. The patient began prophylactic treatment with follow up every three months and he had a favorable clinical course.

Background: Congenital positional, rotational and fusion anomalies of the kidney are frequently encountered. Crossed renal ectopia is a condition in which the kidney is located on the side contralateral to its ureteral insertion into the urinary bladder. Crossed renal ectopia without fusion is a very rare anomaly sporadically reported in the literature. We have attempted to analyse such renal anomalies in a large series of patients. Materials & Methods: Contrast enhanced multidetector computed tomographic scans of 960 patients (491 males and 469 females, age range 4-90 years) were reviewed . Observations: Crossed renal ectopia without fusion was detected in three patients (0.31%; 1 in 320 cases). All three patients were males and left- to-right renal ectopia was noted in two cases and right-to-left ectopia in one case, in whom the ectopic right kidney was exhibiting multicystic dysplasia. An interesting observation was vascularisation of crossed ectopic unfused left kidneys by branches arising from the right common iliac artery. Conclusion: Crossed renal ectopia without fusion is an extremely rare anomaly and may remain asymptomatic without being detected. Multidetector computed tomography angiography is an excellent imaging modality to detect renal positional and rotational anomalies. To the best of our knowledge the present study is the first study to detect renal anomalies in a large series of cases.
ABSTRACT
Crossed renal ectopia is one of the rarest congenital malformations where a kidney is located on the side opposite to the side of its ureteral insertion into the urinary bladder and is generally fused with the normally located ipsilateral mate. Generally this anomaly remains as a silent clinical entity and is incidentally detected during evaluation for other conditions. We report here three such cases of crossed fused renal ectopia detected by multidetector row contrast enhanced computed tomography. Crossed fused renal ectopia of inferior type was observed in a male on the right side with the ureter of the ectopic left kidney crossing the midline. In two female patients, L-shaped or tandem kidney was noted, one on the right and another on the left side. Over all in two cases the left kidney was ectopic and in one the right kidney. No renal pathologies like urinary tract infection, nephrolithiasis or hematuria were found in our patients.
ABSTRACT
Background: Kidneys and ureters demonstrate a wide range of anomalies due to its complex development. One such anomaly would be the crossed renal ectopia which is fusion of both kidneys on to one side and malpositioned at the pelvis. The occurrence of these anomalies, though rare, is due to multifactorial reasons. The renal anomaly was observed in a formalin fixed adult cadaver during the undergraduate medical dissection. The abdominal cavity, on opening, revealed malrotation of the gut with the large intestine on the left side and the small intestinal loops on the right side. The left renal fossa was empty due to fusion of the left kidney with the right kidney forming a lump kidney. The ureter of the left kidney was draining in to its normal position into the urinary bladder. The position of the lump kidney was in the right iliac fossa. It was having arterial feeders from the abdominal aorta and the common iliac arteries and was draining into the inferior vena cava and the right common iliac veins by 5 renal veins. Crossed renal ectopia rarely may be associated with malrotation of the gut. Awareness of such anomalies could be due to incidental finding and helps the surgeons and radiologists in their diagnosis and planning and preventing postoperative complications.
ABSTRACT
Se presenta el caso de un niño cuyo ultrasonido materno-fetal de la semana 20 de la gestación no detectó alteraciones, pero el de la semana 23,6 mostró un riñón pélvico derecho. A los 22 días de nacido el ultrasonido renal mostró un riñón derecho de tamaño y posición normal y dilatación pélvica moderada, e inmediatamente por debajo del polo inferior de éste, un bolsón hidronefrótico que parecía corresponder a una ectopia renal cruzada con hidronefrosis grave. El padre padeció reflujo vesicoureteral derecho que desapareció espontáneamente. A pesar de la profilaxis con cefalexina, hubo una infección urinaria que se trató satisfactoriamente con ceftriaxona. Investigaciones ultrasonográficas y radioisotópicas arrojaron la existencia de una anomalía congénita dada por dilatación pélvica no obstructiva del riñón derecho, ectopia renal cruzada con fusión del riñón izquierdo afuncional y reflujo vesicoureteral bilateral, de grado II del riñón derecho y de grado V del izquierdo ectópico cruzado. A los 11 meses de edad se le realizó una lumbotomía y se comprobó la fusión del bolsón hidronefrótico con el polo inferior del riñón derecho. Se resecó el bolsón y se realizó una ligadura baja del uréter
This is the case of a child whose maternal-fetus ultrasound (US) at twenty weeks pregnancy not detected alterations, but at the 23, 6 weeks it showed the presence of a right pelvic kidney. At twenty two days the renal US showed a right kidney with a normal size and location as well as a moderate pelvic dilation and immediately beneath its lower pole a hydronephrosis big sac in correspondence with a crossed renal ectopia with severe hydronephrosis. His father had right vesiculorectal reflux disappeared spontaneously. Despite the prophylaxis with Cephalexin there was a urinary infection adequately treated with Cephtriaxone. Ultrasonography and radioisotope researches demonstrated the presence of a congenital anomaly due to the no-obstructive pelvic dilation or right kidney, crossed renal ectopia with fusion of dysfunctional left kidney and II degree bilateral vesicoureteral reflux from right kidney and of V degree from the crossed ectopic left kidney. At eleven months life he undergoes a lumbotomy and the hydronephrosis big sac was fused with lower pole of the right kidney. This big sac was resected and a low ureter ligature was carried out

Crossed Fused Ectopia a rare condition is presented here with a discussion on its clinical presentation dignosis and management.
ABSTRACT
Crossed renal ectopia is a congenital malformation in which both kidneys lie on the same side of the spine, usually side by side longitudinally. More often on the right side. Fusion of the two renal units is eight times more common than nonfusion. Although crossed renal ectopia is uncommon, this unusual entity must be considered in an infant when cystic mass in the abdomen or pelvis paticularly if no kidney can be found on the opposite side. In many cases of crossed fused ectopia with multicystic dysplastic kidney(MCDK), the diagnosis can be strongly suspected from the sonogram, and no other studies may be necessary. However, both intravenous urography and isotope renography is useful to assess the function of the crossed kidney. Crossed renal ectopia and MCDKs are associated with a greater incidence of ureteropelvic junction obstruction and reflux. So, screening voiding cystourethrography should be performed. Very few studies of MCDK in the setting of crossed fused ectopia have been reported. We have experienced a 3-year-old boy with crossed fused renal ectopia with multicystic dysplasia.

We report a case of surgically treated abdominal aortic aneurysm (AAA) in a patient having crossed ectopia with fusion anomaly of the kidney. One artery from the abdominal aorta above the aneurysm supplies the right kidney while three renal arteries (two from the aneurysm itself and one from the left common iliac artery) supply the crossed ectopic kidney. Preoperative imaging to define the arterial and collecting systems along with a detailed planning of the operation is essential to prevent ischemic renal injury as well as ureteral injury during AAA repair.

Intrathoracic kidneys are rare developmental anomalies and represent less than 5% of all congenital kidney ectopia. Ectopic intrathoracic kidneys are usually asymptomatic and have normal renal function. This disease occurs more frequently in males and on the left side. We report a case of right intrathoracic kidney with congenital complex cardiac anomalies such as single atrium, patent ductus arteriosus and tricuspid regurgitation.

Ectopic thoracic kidney is an extremely rare developmental anomaly. Most cases are discovered incidentally on a routine chest roentgenogram. Since the ectopic thoracic kidney may be mistaken for a space-occupying lesion originating above the diaphragm, it is of clinical and diagnostic importance to the thoracic surgeon. We report a case of ectopic thoracic kidney that was diagnosed by chest roentgenogram, intravenous pyelogram, computerized tomogram, and aortogram.

When an ectopic kidney is located on the opposite site from its ureteral insertion into the bladder, the condition is known as crossed ectopia. Ninety per cent of crossed ectopic kidneys are fused to the ipsilateral kidney. Herein we report a case of crossed renal ectopia with fusion in a 20 year old male.

Crossed renal ectopia is an unusual congenital anomaly, probably produced by abnormal development of the ureteral bud. The deformity itself produces no symptoms and the clinical presentation generally is for obstruction and infection. The pediatric patients present most often with multiple congenital anomalies, especially of the skeletal system. We report the two cases of crossed renal ectopia with fusion with review of literatures.
