“…These characteristics may lead to ureteropelvic junction obstruction and urinary tract diseases, such as vesicoureteral reflux, UTIs, ureteroceles, renal calculi, malignancy, and renovascular hypertension [ 12 ]. A case similar to ours was reported in 2013 at the Indira Gandhi Institute of Medical Sciences, India [ 13 ]. The patient had a similar reluctance toward the recommended urgent management and follow-up.…”

Among congenital renal anomalies, the ectopic kidney is a rare occurrence. Crossed fused renal ectopia (CFRE) -an even rarer subtype of ectopic kidney -is characterized by both kidneys being fused together on one side of the spine. CFRE is usually asymptomatic but can present with vague symptoms if the anomalous kidney becomes infected, is obstructed by calculus, or has a neoplastic change. There is no indication for surgical intervention if the kidney functions normally. This report presents a case of CFRE in a 31-year-old male with recurrent right flank pain resulting from a large calculus in the upper moiety of the fused kidney. The calculus was surgically removed by percutaneous nephrolithotomy (PCNL). The patient was discharged on analgesics, antibiotics, and potassium citrate tablets, with an order to follow up after one month. On follow-up, the patient's double-J (DJ) stent was removed and an X-ray was performed to rule out any complications. No signs of stones, strictures, or other complications were noticed.

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.
