Congenital ureterovaginal fistula and a duplicated left ectopic ureter: A rare case in Tanzania.

This case report presents the clinical journey of a 28-year-old nulliparous woman from Dar es Salaam, Tanzania, who sought medical attention due to lifelong urinary leakage since birth, profoundly impacting her emotional well-being and sexual encounters. Clinical examination revealed urinary leakage from the vagina, with unremarkable abdominal and genital findings. Laboratory investigations were normal. Computed tomography intravenous urography revealed a left duplex collecting system with significant hydroureteronephrosis in the left upper moiety, suggestive of an ectopic ureter. Intraoperative exploration confirmed a duplicated left ureter, with the upper moiety implanted into the vaginal canal. Surgical re-implantation of both left ureters into the bladder was successfully performed, correcting the anatomical anomaly. Postoperative follow-up demonstrated marked improvement in urinary symptoms, restoring the patient's confidence and alleviating emotional distress. This case underscores the complexity and rarity of congenital urinary tract anomalies, particularly in resource-constrained settings, and highlights the importance of a stepwise diagnostic and management approach.
