Crossed Fused Renal Ectopia With Acute Pyelonephritis: A Case Report

Abstract

Crossed Fused Renal Ectopia (CFRE) is a very rare anomaly of the kidneys with a prevalence of 1 in 1000 live births. In this condition, both kidneys are fused together on one side of the spine. Usually, CFRE is an asymptomatic condition and is mostly detected incidentally, but sometimes the patient may develop various renal signs and symptoms. We report a case of acute pyelonephritis in a crossed fused right renal ectopia which was diagnosed by renal ultrasound and confirmed by computed tomography in a 75-year-old female.

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

“…Type C and D are very rarely found in clinical practice. CRE is more frequently identified in males, and left-to-right crossing ectopy is three times more common than right-to-left crossing ectopy [ 1 ], as in our study.…”

“…Since CRE is generally asymptomatic, most cases are discovered fortuitously. Some cases, however, may cause symptoms such as lumbar or epigastric pain, a palpable mass, hematuria or dysuria, which are the most common signs [ 1 ]. CRE can also be associated with urological complications like vesicoureteral reflux, ureterocele, ureteropelvic junction obstruction, urinary tract infections, hydronephrosis, nephrolithiasis, and in rare cases, cancer [ 6 ].…”

“…Renal ectopy is a urological and congenital anomaly in which one or both kidneys are located in an unusual position. Ectopic kidneys come in different shapes and sizes, such as thoracic kidney, pelvic kidney, and crossed renal ectopy [CRE] [ 1 , 2 ]. CRE is the transposal of a kidney to the opposite side.…”

“…Most cases go undiagnosed in pediatric patients, as they are asymptomatic [ 2 ]. Pyelonephritis in patients with CRE is fairly rare [ 1 ]. This case was reported according to SCARE criteria [ 4 ].…”

A Rare Case of Obstructive Uropathy in an Elderly Male From Rural India - A Case Report

“…Imaging modalities like ultrasound, anterograde pyelography, intravenous urography, computed tomography, and magnetic resonance imaging are used to make the diagnosis of the diseases of the urinary system and its anomalies [ 14 ].…”
