Summary
A rare urinary tract anomaly, ureteral triplication, was observed in a 42-year-old male with right triplicated and left duplicated ureters. The patient presented with gross hematuria, linked to bleeding from a lower ureteral orifice.
Area of Science:
- Urology
- Medical Imaging
- Anatomical Variations
Background:
- Ureteral triplication is an exceptionally rare congenital anomaly of the urinary tract.
- This case presents a unique instance of right ureteral triplication alongside left ureteral duplication.
Observation:
- A 42-year-old male presented with gross hematuria, which resolved spontaneously.
- Diagnostic imaging, including CT scan and renal angiography, revealed no significant pathology.
- Cystoscopy identified three ureteral orifices on the right, with bleeding originating from the inferior one.
Findings:
- Right retrograde pyelography demonstrated three distinct renal pelvic systems.
- The lower and middle pelvic systems exhibited calyceal communication.
- The observed anomaly aligns with an altered Type-D classification by Smith.
Implications:
- This case contributes to the limited literature on ureteral triplication and its clinical manifestations.
- Highlights the importance of comprehensive urological evaluation for unexplained hematuria.
- Further research into the embryological basis and long-term management of such rare anomalies is warranted.
