Retrocaval ureter, also known as circumcaval ureter, is a rare congenital anomaly which commonly presents with loin pain in middle age group. Here, ureter passes between the inferior vena cava (IVC) and psoas muscle and gets compressed. Duplication of IVC is another rare congenital anomaly in the development of IVC. We present a case of a 49-year-old male who presented with loin pain and upon thorough investigation was found to have retrocaval ureter along with duplication of the infrarenal IVC. We bring forward this rare type of combination of two congenital malformations.

Retrocaval Ureter

Background: Retrocaval ureter also referred to as circumcaval ureter or preureteral venacava is a rare congenital anomaly with the ureters passing posterior to the inferior vena cava (IVC). The ureter classically course medially behind the inferior venacava winding around it and then passes laterally in front of it to then course distally to the bladder. Though it is a congenital anomaly, patients do not normally present with symptoms until the 3rd and 4th decades of life from a resulting hydronephrosis. This hydronephrosis may be due to kinking of the ureter. The ureteric segment is a dynamic or compression against the psoas muscle. It was initially considered as aberration in ureteric development; however current studies in embryology have led to it being considered as an aberration in the development of the inferior vena cava. Objectives: The aim of our study was to explore the safety, feasibility and usefulness of retroperitoneoscopic surgery for retrocaval ureter performed in a single centre and to assess the short-term outcomes of patients treated with this surgical approach. Materials and methods: Eight patients underwent retroperitoneoscopic transposition of ureter between March 2014 and November 2016, A 3-port, ballon-dissecting, retroperitoneal approach was used, no open conversion was required. Follow-up studies were performed with intravenous urography and ultrasonography. Results: Mean operating time was 121 minutes (range 92-178) and mean anastomotic time was 56 minutes for all cases. Blood loss was minimum. None of the patients required blood transfusion. No intraoperative complications occurred. Hydronephrosis in all patients were decreased substantially after surgery. Conclusion: Our results have demonstrated that retroperitoneoscopic transposition of ureter is an excellent minimally invasive treatment option for a retrocaval ureter that can be accomplished quickly and safely.

Retrocaval ureter is an uncommon cause of ureteric obstruction due to a rare congenital anomaly of inferior vena cava. We report a case of 23 year old male who presented with right flank pain and was diagnosed with ultrasound and intravenous urography. He underwent open retroperitoneal ureteroureterostomy.

AbstractRetrocaval ureter is a rare congenital anomaly which has a incidence of occurence of one in 1500 live births. It is known to occur 2.8 times more commonly in males than females. While carrying out a study on congenital anomalies in urinary system in a collection of still born fetuses, a case of retrocaval ureter was noticed in a still born male foetus. In Retrocaval ureter, ureter is S shaped on the right side and a part of inferior vena cava is anterior to the proximal part of the ureter. Here the development of ureter is normal. Whereas the development of inferior vena cava is abnormal.

Retrocaval ureter (RCU) is a rare congenital anomaly in which the ureter passes posterior to the inferior vena cava (IVC). A little over 200 cases have been reported worldwide since Hochstetter’s first report in 1893. We present two cases of retrocaval ureter which were successfully managed at the Cape Coast Teaching Hospital in Ghana. Case 1. A 55-year-old woman presented with a history of dull right flank pain of 2 years duration. Physical examination and basic laboratory investigations performed on her were normal. Abdominal ultrasound showed right hydronephrosis and a retrograde right ureteropyelogram (RPG) showed right hydroureteronephrosis with an “S” shaped proximal ureter. A diagnosis of retrocaval ureter was made and confirmed at surgery. Case 2. A 25-year-old man presented with dull intermittent right flank pain of 1 year duration. Clinical examination and laboratory investigation were normal. Abdominal ultrasound showed right hydronephrosis and a CT urogram made a diagnosis of retrocaval ureter which was confirmed at surgery. Conclusion. Retrocaval ureter is a rare congenital anomaly that is now increasingly being reported. Surgical treatment of symptomatic cases successfully relieves symptoms.

A horseshoe adrenal gland is a rare congenital anomaly found almost exclusively in neonates and infants based on autopsy studies. It is a term used to describe a solitary adrenal gland situated in the midline, posterior to the inferior vena cava and abdominal aorta. To date, in the literature, there have been very few cases documented in adults and they have also been reported to be associated with other co-existing intra-abdominal, vascular and vertebral congenital anomalies. We describe a rare case of an asymptomatic adult patient who was incidentally found to have a horseshoe adrenal gland as well as a Type 1 diastematomyelia.

Objective: To determine the prevalence of inferior vena cava (IVC) anomalies in Thai patients who underwent contrast-enhanced computed tomography (CT) of the abdomen. Materials and Methods: Two radiologists retrospectively and independently reviewed the contrast-enhanced abdominal CT examinations in 1,429 Thai patients between August 1, 2018 and January 25, 2019 who met the inclusion criteria. Patients were included, if (a) their CT showed well visualized IVC, renal veins, and right ureter that were not obliterated by tumor, cyst, fluid collection, or intraperitoneal free fluid, (b) they had not undergone previous abdominal surgery that altered anatomical configuration of the IVC, renal veins, and right ureter. The presence of all IVC anomalies were recorded. Results: Among the 1,429 studied patients, 678 were male (47.4%) and 751 were female (52.6%). The prevalence of IVC anomalies was 3.5%. Five types of IVC anomalies were presented. The most common was circumaortic left renal vein in 24 patients or 48.0% of all IVC anomalies and 1.7% of the study population, followed by retroaortic left renal vein in 15 patients or 30.0 % of all IVC anomalies and 1.0% of the study population. Other IVC anomalies included double IVC, left IVC, and retrocaval ureter at 0.5%, 0.2%, and 0.1% of the study population, respectively. Conclusion: The prevalence of IVC anomalies in the present study differed from the previous studies conducted in other countries, which may be attributable to differences in race and ethnicity. Awareness of these anomalies is essential when evaluating routine CT examinations in asymptomatic patients. Their presence should be carefully noted in radiology reports to avoid anomaly-related complications.
