“…Some authors claim that a cap of nephrogenic tissue representing the remnant of the metanephric blastema ( 6 , 7 ) or a fibrous band connecting the upper blind extremity with a metanephric remnant ( 3 ) may be present, while others have not reported such observations ( 8 ) .…”

Aim of the study: We report a case of a blind-ending bifid ureter in a 67-year-old woman with ascites initially diagnosed with B-mode and Color Doppler ultrasonography and afterwards verified with contrast-enhanced abdominal computed tomography. A literature review of the pathogenesis, sonographic appearance with differential diagnoses and clinical significance is also presented and discussed. Case description: The patient was referred for an abdominal ultrasound due to enlarged abdomen circumference. Ultrasound revealed signs of chronic pancreatitis with cavernous transformation of the portal vein and large ascites resulting in bilateral pelvicalyceal system dilatation. Additionally, we have preliminarily diagnosed right-sided, dilatated blind-ending bifid ureter with associated contralateral complete duplication of the ureter and the collecting system. These findings, initially revealed with ultrasound, were confirmed with contrast-enhanced abdominal computed tomography. Conclusions: To our knowledge, this is the first detailed description of sonographic appearance of blind-ending bifid ureter.

“…Most cases are diagnosed during common urological investigations such as intravenous urography, retrograde pyelography, or diagnostic cystoscopy. Computed tomography and MRI are also capable of detecting these anomalies, but this is dependent on the scan protocol that is used [6] , [7] . In particular, the value of multidetector computed tomography imaging using multiplanar reformats and 3D reconstructions to establish the diagnosis has been described in the literature.…”

Anatomic variants of the urinary tract are relatively common; however, a bifid ureter with a blind-ending branch is a rare congenital anomaly. This variant often goes unnoticed because patients are either asymptomatic or complain of vague abdominal symptoms. Diagnosis is often incidental, and may be missed on conventional imaging. Although bifid ureters usually do not require any specific investigations or treatment; it is important to have an appreciation for these anomalies particularly if radiological intervention or surgical procedures are planned. We describe a case of a blind-ending bifid ureter in a patient with bilateral hydronephrosis secondary to a large cervical malignancy. The presence of the bifid ureter was only appreciated during a technically challenging antegrade ureteric stent insertion several weeks after diagnosis. We review the clinical significance, embryology, and radiology findings of this anomaly, as well as the implications during radiological interventional procedures.
