Background: Crossed renal ectopia with fusion is the abnormal migration of the kidney to the opposite side of the insertion of the ureter to the bladder. It is the second most common congenital anomaly of the kidney and urinary tract preceded by horseshoe kidney. The following article serves to highlight the anomaly in a conglomeration of 17 unique cases, managed in our tertiary care centre over a period of 5 years. Materials and Methods: This is a descriptive study analysing the demographic features and the management of seventeen patients diagnosed with crossed renal ectopia with fusion during the period January 2012 to January 2017. Radiological modalities of investigation were modified as per the anomaly. The management plan was devised keeping in mind, the essence of preserving the functional unit. Results: Of the seventeen cases, nine patients were symptomatic and eight were asymptomatic. The most recurring crossed renal ectopia with fusion was L- shaped (n=6), disc shaped (n=6) sigmoid shaped (n=2), inferior (n=1), cake shaped (n=1) and superior ectopia (n=1). Left to right ectopia (n=9) was more common than right to left (n=8). Three patients had a solitary crossed ectopia. Out of nine symptomatic patients, six patients underwent surgical procedures, the remaining three were treated conservatively and advised regular biannual follow-up with imaging. Conclusion: The management of crossed renal ectopia with fusion is individualised according to the underlying urological anomaly and its sequelae. Importance is given to preserve the renal function whenever possible. Reconstructive surgeries like pyeloplasty, ureteric reimplantation, boari flap can salvage some function in these units.

Crossed fused renal ectopia is a rare congenital anomaly of renal embryogenesis. The majority of such anomalous kidneys are supplied by a single renal artery and drained by two separate ureters. However, drainage by a single common ureter is an unusual variant. Here, we present a 17-year old male with a pelvic pancake kidney drained by a single ureter with associated acute obstructive uropathy diagnosed with ultrasonography and computed tomography urography (CTU). We describe the anatomical peculiarity and diagnostic evaluation of the case.

“…Most cases of renal ectopia remain asymptomatic throughout the patient’s lifetime and are diagnosed incidentally [5]. Patients usually present with intermittent episodes of lower abdominal or flank pain, burning micturition, episodes of hematuria, dysuria, and other constitutional symptoms like fever owing to infection in 30% of cases [6]. Nephrolithiasis, ureteropelvic junction obstruction, and hydronephrosis are associated with this condition [3,5-8].…”

Crossed fused renal ectopia with a single ureter and single renal vein is a rare congenital anomaly in which both the fused kidneys lie on one side of the body. We present an unusual case of crossed fused renal ectopia with a single ureter, single renal vein, and a calculus in a 22-year-old man who presented with lower abdominal pain, burning micturition, and a right-side abdominal lump present for three months. On abdominal ultrasound and non-contrast computed tomography (CT), the left kidney was not visualized in the left renal fossa. However, we noted it on the right side, fused to the lower pole of the right kidney with a calculus within the pelvis leading to mild hydronephrosis. After intravenous administration of non-ionic contrast medium, we saw a single ureter draining both the moieties into the urinary bladder on the right side. A three-dimensional volume rendering technique revealed a single renal vein draining the renal parenchyma into the inferior vena cava. Cross fused renal ectopia is an uncommon congenital anomaly which remains asymptomatic throughout life and undetected in the absence of renal pathologies. Multi-detector computed tomography (MDCT) is an excellent tool for denoting anatomical details of this anomaly; the information provided by MDCT is crucial for surgeons, nephrologists, and radiologists alike in facilitating proper management of the condition.
