RELATIONSHİP BETWEEN RETROAORTIC LEFT RENAL VEIN AND PATIENTS PRESENTING TO THE EMERGENCY DEPARTMENT WITH MICROHEMATURIA
Introduction: Microhematuria is the presence of an abnormally high number of erythrocytes in the urine. This microscopic hematuria, not visible to the naked eye, can generally be detected through urine analysis. The causes of microscopic hematuria encompass a range of pathological conditions, from simple urinary tract infections to urolithiasis, trauma, urological cancers, and vascular diseases.
Method: A single-center and retrospective research in an educational and research hospital's emergency department. Patients who presented to the emergency department between January 2020 and April 2023, were diagnosed with microhematuria based on laboratory tests, and underwent abdominal computed tomography were included in the study.
Finding: Out of the 1499 patients with detected microhematuria in the emergency department and whose retrospective abdominal CT scans were evaluated, 780 (52%) were female, and the mean age of the patients was 43.9 ± 18.2 (min: 18; max: 95). Based on the patients' medical histories and the results of tomographic examinations, urinary tract stones were identified as the most common cause of microhematuria, followed by cystitis, pyelonephritis, kidney stones, and left retroaortic renal vein.
Discussion: In the emergency department, investigating the etiology of microscopic hematuria detected during the evaluation of symptomatic or other presenting patients may be necessary. This is because, although the causes of microhematuria are often benign, it is essential to catch malign causes in the early stages. In addition to benign and malignant causes, there may be rare but significant congenital malformations that require monitoring
Conclusions: A significant association between retroaortic left renal vein and microhematuria has been observed. After excluding the potential common causes of microhematuria, renal vascular anomalies should be considered as a possibility. Clinicians should consider retroaortic left renal vein as a differential diagnosis in patients with unexplained microhematuria and radiology experts should keep this anatomical variation in mind when evaluating abdominal CT scans.
