“…(Table 1) Urogenital anomalies observed with CRE without fusion include hypospadias, infertility, anorchia and ectopic ureteric opening. [4,7,15]. Anal atresia was present in a boy and in another, more severe anomalies like hydrocephalus, scoliosis, meningomyelocele and pes equinovarus were seen.…”

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.

“…It may be discovered incidentally during investigations for another disease [ 5 , 10 ]. It can also present with urinary symptoms due to UTIs [ 11 ] or an abdominal mass leading to abdominal pain or constipation [ 3 , 12 ]. The crossed kidney may also have renal or ureteric calculi [ 10 ].…”

“…Although non-fused CRE can be identified by ultrasonography, a CT urogram can help to determine the course of the ureter. It can identify any hydronephrosis, hydroureter, renal calculi, or other urinary tract abnormalities [ 11 ]. A technetium-diethylenetriamine pentaacetate (99mTc-DTPA) scan can also be used to evaluate kidney function [ 15 ].…”

A Rare Case of Crossed Non-fused Ectopic Kidney

Crossed and non-fused kidneys are an exceedingly rare congenital anomaly in which one or both kidneys cross the midline to the opposite side. At the same time, the ureters are inserted in their normal anatomical locations in the bladder. Although crossed ectopic kidneys are mostly asymptomatic and incidentally discovered during workup for other disorders, they are prone to urological complications such as urinary tract infections (UTIs). Here we present the case of a 12-year-old male with a history of recurrent UTIs and urinary retention who presented to the emergency department with recurrent UTIs and urinary retention and was eventually found to have an ectopic unfused left kidney in the right lumbar region on computed tomography (CT).

“…The most frequent are renal agenesis [67], cystic seminal vesicle, and ipsilateral renal dysgenesis [50,68]. Other reported associations include renal agenesis and congenital pouch colon [69], crossed renal ectopia [70], and "right sided syndrome" (absence of testis and vas deferens, ipsilateral adrenal agenesis, unicornuate uterus, and vertebral defects, imperforate anus, tracheoesophageal fistula, and radial and renal dysplasia-VATER association) [71].…”
