Background: Congenital malformations of the kidney and urinary tracts happen in 3-6 per 1000 live births and these abnormalities are the reason, for (ESRD) in children and also the reason for subsequent kidney problems such as kidney stones, infections and hypertension in adulthood. One of the most common anomalies of the renal system is the double collecting system. Knowledge of anatomical variations and disorders before surgery can make the surgical procedure smoother for the surgeon and prevent unwanted mistakes. Imaging through radiology, computed tomography, and MRI is the best way to diagnose early, follow-up, and planning for surgery, diagnosis of complications and extra kidney abnormalities.
Case Presentation: Our report in this article is about four years old girl who went to the MRA center of Baath Hospital in Sanandaj due to flank pain in December 2019. After abdominal imaging, signs of an abnormality of the double collecting system were revealed. Abdominal and pelvic ultrasound revealed abnormalities of the UVJ, and the distal part of the right urethral duct was approximately 2 mm in size. Also, the anterior-posterior diameter of the right renal pelvis was reported to be 2 mm and the upper calyx of the right kidney was quite dilated. This incomplete integration leads to complete or incomplete forms of the renal collecting system. The prevalence of this anomaly is also mostly unilateral, but our report, in this case, is about bilateral ureters.
Conclusion: We reported a rare case of bilateral Y-shaped bifid ureter, that's in this kind of anomaly 2, pyelocaliceal systems connect at the junction of the ureter to pelvic (bifid pelvis), and this abnormality was accidentally detected on ultrasound and MRI examinations. However, since duplex kidneys are often asymptomatic and therefore mainly diagnosed incidentally in patients, the actual number of patients with symptoms is probably lower.
