Incidence of Bifid Ureter and Its Clinical Significance: A Cadaveric Study

Why is it important?

Introduction: Bifid ureter or incomplete type of double ureter is a rare congenital anomaly where separate pelvicalyceal system drain into separate ureter because of branching of ureteric bud, but they unite before draining into urinary bladder to open through single ureteric orifice. It’s more common in females and on right side. Objectives: The knowledge about the incidence of bifid ureter and its surgical and embryological significance is of immense value for urologist and renal transplant surgeon. Methods: 25 cadavers embalmed in 10% formalin formed material of this study, identification of bilateral ureter and tracing of their course till urinary bladder was done, bifid ureter were seen on right side. After removal of intestine and mesentery, posterior abdominal wall was exposed, kidneys were cleaned by removing the fascia and meticulous dissection was done to trace ureters till pelvic cavity, number of bifid ureter were noted and photographs were taken. Results: 2 cases showed presence of bifid ureter on right side where two ureters were descending down from the hilum posterior to renal vessels were seen, in one case they were uniting at a distance of 13.5 cm and in second case at a distance of 3.5 cm from the ureteric opening into urinary bladder. Course of ureter in pelvis was normal. Conclusion: Review of literature suggests that duplication of ureter is seen very infrequently. It may be an accidental radiological finding in a patient or may be detected during autopsy. Therefore surgeons and clinicians should be aware of this anomaly to prevent iatrogenic injuries during surgeries and treating renal pathologies.
