Migration of a kidney to the contralateral side is referred to as Crossed Ectopia. Simple renal ectopia can be unilateral or bilateral and is due to the partial arrest of normal renal ascent or excessive ascent. The reported incidence of simple renal ectopia is 1:500 to 1:1100 cases and is more prevalent on the left side without any significant difference in between the sexes. Though ectopic kidneys may remain asymptomatic, they are more susceptible to develop hydronephrosis and renal calculi. Materials and Methods: We have retrospectively reviewed multidetector computed tomography angiographic scans of 960 patients (491 males; 469 females). Observations: We have observed simple renal ectopia in seven patients (5 males and 2 females; 0.73%) which is higher than the reported incidence. We have observed 4 kidneys in pelvic, 2 in lumbar and 1 in iliac position. Out of 7 ectopic kidneys, 5 were on the left side and 2 on the right side. Hilum was abnormally positioned in all ectopic kidneys due to disturbance in axial rotation. In three cases the ectopic kidneys received arterial supply from the contralateral arteries arising from aorta or common iliac arteries which is a rare phenomenon. Renal calculi and hydronephrosis were noted in two cases. Conclusion: Presence of an ectopic kidney might result in an atypical pattern of referred pain which may be confused with appendicitis or pelvic inflammatory disease, especially in women. Presence of an ectopic pelvic kidney can lead to complications during pelvic surgeries. Multidetector computed tomography angiography is an excellent imaging modality not only useful to define prevalence of renal ectopia in general population but also to detect associated complications and vascular anomalies in a single investigation.

متن کاملLeft crossed fused renal ectopia L-shaped kidney type, with double nutcracker syndrome (anterior and posterior).
Crossed fused renal ectopia (CFRE) is the second most common fusion anomalies (FAs) of the kidneys after horseshoe kidney. Crossed fused renal ectopia (CFRE) results from one kidney crossing over to the opposite side and subsequent fusion of the parenchyma of the two kidneys. We report, by multidetector-row computed tomography (MDCT) angiography, an extremely rare case of a left CFRE (L-shaped ...

The aim of this study was to reveal biometric peculiarities of New Zealand white rabbit antebrachium (radius and ulna) by means of three-dimensional (3D) reconstruction of multidetector computed tomography (MDCT) images. Under general anesthesia, the antebrachiums of a total of sixteen rabbits of both sexes were scanned with a general diagnostic MDCT. Biometric measurements of the reconstructed...

UNLABELLED Renal ectopia occurs in 1:3000-1:7000 children. Simple ectopia refers to the abnormal kidney location on the same side; in crossed ectopia the ureter crosses the midline of the body. In most cases ectopic kidney is found in the pelvis minor, in 5% of cases in the thoracic cavity. Kidney displacement does not give any clinical symptoms in the majority of patients, sometimes it may cau...
