“…The reflux is also responsible for the fact that the blind-ending ureter is only partially emptied, therefore giving rise to stagnation of the urine in the blind-end and a greater propensity for urinary infection and stone formation. Rare cases of urothelial carcinoma have been reported in the blind endings of bifid ureters [ 8 , 9 ].…”

Patient: Female, 49-year-old Final Diagnosis: Bifid ureter with blind ending Symptoms: Lumbar pain • urinary infection Medication: — Clinical Procedure: — Specialty: Urology Objective: Rare disease Background: The blind-ending branch of a bifid ureter is a rare congenital anomaly which is usually asymptomatic but can occasionally give rise to various symptoms, such as chronic abdominal pain. Diagnosis is most often confirmed radiologically, and treatment is usually conservative. Surgical resection of the blind ending of a bifid ureter should be considered in cases of persistent symptoms. Case Report: A female patient of 49 years of age presented with intermittent right lumbar pain, repetitive urinary infections and microscopic hematuria. We present here the diagnostic work-up of the case, leading to the identification of the existence of ureteral bifidity located at the lower third of the ureter and of a blind ending of the bifid ureter. Several regimens of various antibiotics failed to resolve the symptoms. It was decided to carry out a laparoscopic resection of the blind ending of the bifid ureter. We describe the practical procedures of the surgical operation and discuss briefly the embryological etiology and the physiopathology of the condition as well as the principal diagnostic modalities. Since the surgery, the patient has been symptom-free. Conclusions: Despite being usually asymptomatic, the rare congenital anomaly of a bifid ureter with a blind ending can occasionally give rise to symptoms such as recurrent infections and persistent abdominal pain. Laparoscopic-based resection of the blind ending should be considered in such cases.
