Anatomical variations of ureter in central India: A cadaveric study

Abstract

Background: Duplication of ureter is a developmental anomaly of urogenital system. The possible embryological reasons for the formation of a duplicated ureter could be splitting of ureteric bud, resulting two ureters draining into single kidney. Prevalence occurs in approximately 1% of the population. It may be associated with or without other congenital defects. Aim: To study the major anatomical variations of the ureter in routine dissection method. Materials and Methods: The present study conducted in the Department of Anatomy on 156 formalin-fixed cadavers of both sex and focus on the ureteric anomaly in routine dissection method. The ureter was followed from the renal pelvis to the uretrovesical junction, an opening into the urinary bladder (UB). Out of them, we got in one cadaver that two ureters were draining a single kidney into the UB separately and were not associated with any other congenital anomaly. There was complete duplication of ureter on unilateral side (left). Right kidney and its ureter were entirely normal. Conclusion: The knowledge of abnormality in renal collecting system is necessary for effective endo-urological applications and intrarenal surgeries. The present study adds on to the literature and will be helpful and interesting for the radiologists and urologists as it describes the ureteric anomaly in the Central Indian population.
