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.

“…Alessandrini reported 5 cases of pediatric ureter blind ending; all diagnosed by cystography and he said that this examination should be performed in the first step of investigation of urinary tract in children [ 8 ]. Abdominal CT shows when it's a hernia of the intestine which is the most frequent, an agglutination of the small intestine with the air-fluid levels in the pelvic cavity.…”

Hernia through a defect of the broad ligament is extremely rare in children. These defects can result from a developmental defect or a spontaneous rupture of cystic formations remnants of mesonephric ducts or Müller. Genital anomalies associated with unilateral renal agenesis are more common in females. We report the case of a 13 months girl allowed for assessment of recurrent urinary tract infection; abdominal examination did not objectified palpable mass, the external genitalia were without abnormalities. Abdominal ultrasound revealed a left renal space is empty with a retrovesical cyst. Cystography was requested that objectified a large pelvic cystic mass retrovesical communicating with the bladder, there was also a left vesicoureteral reflux. Uro- MRI showed a cystic formation retrovesical communicating with the bladder, the right pelvic kidney; uterus is normal size for age. DMSA scintigraphy confirmed the absence of the left kidney with the right kidney that ensures 100% of total renal function. To surgical exploration we found a hernia of the bladder through the left broad ligament, the uterus was dislocated on the right side; left ovary was hypoplasic; the ipsilateral ureter was blind with renal agenesis, we performed by reduction of the bladder then closing the hernial orifice, dissection of the ureter with its ligation and section at the vesical stoma. The postoperative course was uneventful. Evolution is favorable. This observation illustrates a hernia of the bladder through the broad ligament associated with ovarian hypoplasia, renal agenesis and ipsilateral ureter blind ending; this association was not described to our knowledge in the literature.

A case of bilateral urolithiasis and renal insufficiency with a blind-ending branch of the right bifid ureter is presented. The diagnosis was made by retrograde ureterogram which revealed a blind-ending branch originating in the middle third of the right ureter. Stones were treated with phased extracorporeal shock wave lithotripsy after preliminary bilateral JJ stenting. The renal parameters reverted to normal and the patient was stone-free.
