Recurrent urinary tract infections led to the diagnosis of cross-renal ectopia: A case report

INTRODUCTION: Crossed renal ectopy (CRE) is a very rare congenital kidney anomaly. CRE is usually asymptomatic and is most often discovered incidentally, but the patient may sometimes develop various renal manifestations. CASE PRESENTATION: We report a case of a girl who was symptomatic of several episodes of urinary tract infections and whose investigations including ultrasound, uroscan, renal scan and voiding cystourethrogram concluded that she had a crossed left renal ectopy without vesico-ureteral reflux. A regular Follow-up revealed no further symptoms or complications, with partial resolution of the hydronephrosis, and no recurrence of urinary tract infections after hygienic rules. This case didn't require surgical intervention. CLINICAL DISCUSSION: CRE is an infrequently occurring congenital malformation. Uroscan is an excellent tool to describe the full anatomical details of this pathology; and the information provided is crucial for surgeons, nephrologists, and radiologists to aid in the proper handling of this pathology. CONCLUSIONS: CRE is a rare disease that can be diagnosed incidentally. Treatment is only indicated if complications occur or if there is other associated renal disease. Patients require continuous follow-up and need to be examined for potential complications.
