“…Type 1 includes an inherent abnormality in the growth of the retrocaval section of the ureter leading to a blockage syndrome that needs surgical removal; type 2 is caused by external pressure on the regular ureter in its retrocaval area, which can be treated with plasty instead of removal [ 1 ]. One of the primary causes of its delayed diagnosis, and in some cases even after death, is its secretive development [ 11 ]. Symptoms typically develop in the third or fourth decade of life as a result of ureteral compression, leading to ureteral kinking and hydronephrosis either from the inferior vena cava pressing against the psoas muscle or from a nonfunctional retrocaval ureteral segment [ 12 ].…”

The retrocaval ureter is an uncommon anomaly where the ureter passes behind the inferior vena cava. Open surgery had been the gold standard for treatment. We are presenting a case of the retrocaval ureter with ureteral calculi, which was effectively managed by open surgery. A 27-year-old male presented with a nine-month history of flank pain. He had no history of chronic illnesses. Physical examinations and laboratory findings were within normal. A computed tomography (CT) scan was done to confirm the diagnosis of retrocaval ureter with ureteral stones. The subcostal incision was made. Then, the proximal and lower ureter was transected at the point where it went retrocaval. The stones were extracted; then, watertight anastomosis was done. Ultrasound used for the follow-up of the patient for six months showed no hydronephrosis. Retrocaval ureteral may have no symptoms or be linked to nonspecific symptoms. The diagnosis of the retrocaval ureter is frequently delayed. Surgical management is utilized in the majority of cases.

Diagnostic dilemma and surgical management of circumcaval ureter: A case report

Circumcaval ureter (CVU) is an uncommon congenital anomaly, in which the proximal ureter makes a loop posterior to the inferior vena cava (IVC) usually resulting in ureteric obstruction with consequential hydronephrosis and a right nonfunctioning kidney. It is also called a retrocaval or postcaval ureter. CVU is rarely encountered and, hence, may pose a diagnostic dilemma for radiologists and urologists. Clinical presentation occurs in the 3rd and 4th decades of life, manifesting mainly with flank pain. We present our experience in the diagnosis and management of CVU in a Nigerian Centre. A 56-year-old man presented with a 2-year history of recurrent, colicky right flank pain. He had been seen in multiple tertiary hospitals with no definitive diagnosis or treatment. A computerised tomography urogram showed an abnormally dilated proximal ureter with the classical fish-hook appearance and medial displacement, posterior to the IVC. At surgery, via an open, flank, extraperitoneal approach a CVU was found with significant stenosis and prestenotic dilatation. An excision of the stenotic segment with ureteroureterostomy was performed over a 6F D-J stent, and he had a smooth postoperative period. A CVU is extremely rare, and hence, the diagnosis can be missed. If left unattended, CVUs can progress to hydronephrosis and, eventually, a nonfunctioning right kidney. A high index of suspicion and early surgical intervention are key to a successful outcome.
