RETROCAVAL URETER (or PRE-URETERAL VENA CAVA) is a rare congenital abnormality arising from dysgenesis of the inferior vena cava (IVC) that results in the right ureter coursing posterior and medial to the inferior vena cava (IVC), causing varying degrees of obstructive proximal hydroureteronephrosis, a rare cause of long-standing cyclical flank pain. Retrocaval ureter (or Pre-ureteral vena cava) is asymptomatic until the 3rd and 4th decades of life from resulting hydronephrosis. Ultrasonography (USG), Intravenous urography (IVU), nuclear scintigraphy, Computed tomography urography (CTU), and Magnetic resonance urography (MRU) have been used in the diagnosis of this abnormality. Computed tomography urography (CTU) depicts the findings in three dimensions gives the most “wholesome” solution to its diagnosis. This condition is differentiated from other urinary tract obstruction causes, especially urolithiasis, essential for successful surgical management. When symptomatic, the situation is treated surgically, either by laparoscopic or open surgery. We report a case of a 50 years old male both with right flank pain and associated hydronephrosis.

Supernumerary kidney is a rare clinical entity with fused supernumerary kidney being even rarer. Caudally located fused right supernumerary kidney with multiple nephrolithiasis was diagnosed in a 69-years-old lady by Computed Tomography Urography. A separate renal artery arising from the abdominal aorta as well as separate renal vein draining into the inferior vena cava was present along with right sided bifid collecting system. Embryological basis of origin of supernumerary kidney, its diagnosis, clinical significance and management are discussed.

Retrocaval Ureter

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.

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.

Case Presentation: A 55 year-old female presented to the emergency department with left sided abdominal pain and hematuria. Computed tomography scan of her abdomen and pelvis demonstrated a large left renal mass with extension into the left ureter, left renal vein, and inferior vena cava. She was admitted and treated for presumed renal cell carcinoma (RCC). Discussion: RCC may present with abdominal or flank pain and hematuria, but more commonly presents with vague symptoms. RCC should be suspected in a patient presenting with hematuria and abdominal or flank pain, especially if vague symptoms such as fatigue or anorexia are also present.
