Abstract
IntroductionUreteral ectopia is a rarely observed anomaly. It may be totally asymptomatic. An association with a duplex system is exceptional. Diagnostic and therapeutic approaches are challenging. Carcinologic surgery must consider the anatomic variant, mainly related to the ectopic site of the ureteral orifice.ObservationWe report a case of a ureteral urothelial carcinoma in a North African 52-year-old male patient, in a right duplex system. Radiological explorations concluded a non-functional upper right kidney.A suspect mass was observed in the lumbar part of the ureter of the right upper system. The meatus of the tumorous ureter ended in the right lobe of the prostate. A right hemi-nephro-ureterectomy was performed. A histological examination concluded a pT2G2 urothelial carcinoma.ConclusionEven if malignancy is rarely observed in ureteral ectopia, it should be evoked mainly in cases of hematuria with risk factors for urothelial tumors.
Highlights
Ureteral ectopia is a rarely observed anomaly
Ureteral ectopia is a rarely observed condition. It is more frequent within women and on the right side, with a sex ratio of 1:12 [1]. This malformation is related to a low insertion of the ureteral bud on the mesonephric canal
The persistence of the ureteral meatus orifice on the mesonephric canal leads to its anastomosis out of the bladder [2]
Summary
Ureteral ectopia is an extremely rare congenital malformation. Certain forms remain asymptomatic for a long time and sometimes go unnoticed. Case presentation A 52-year-old North African man, who smokes 30 packs of cigarettes per year, consulted for intermittent total and clotting hematuria for 2 weeks, without other functional complaints There was no localized tenderness and no palpable mass in the lumbar fossae The lower pole of his right kidney had a normal aspect, and was extended by a non-dilated ureter, suspicious for a double excretory system. There was a left ureteral bifidity, with two systems secreting and excreting normally, without suspect lesions of the excretory tract (Fig. 3). An aspirative drainage of the lumbar fossa and the retropubic space was left at the end of the intervention A thoraco-abdomino-pelvic scan performed every 6 months during follow-up was without anomalies
