Ectopic ureter managed by unilateral nephrectomy in two female horses.

This research article details the successful treatment of urinary incontinence in two young fillies via unilateral nephrectomy after they were diagnosed with unilateral ureteral ectopia.

Background of the Study

• The study evaluated the cases of two fillies aged three years and ten months with a condition called ureteral ectopia, a congenital disorder where one or both of the ureters don’t connect properly to the bladder.
• The condition led to urinary incontinence in both fillies from birth.

Proposed Treatment

• Initially, the researchers planned to reimplant the displaced ureter back onto its correct position on the bladder for one of the fillies. However, during the operation, this was found to be impractical.

Changes in Treatment Approach

• Given the impracticality of the initial approach, surgeons decided on an alternate approach, a unilateral nephrectomy. This surgical procedure involves the removal of one kidney.
• The unilateral nephrectomy was performed successfully on both young fillies.

Results and Conclusion

• Post-surgery, the urinary incontinence in both horses was resolved. They showed normal urinary function.
• Both horses became healthy and serviceable post-operation, suggesting that unilateral nephrectomy is an effective treatment for ureteral ectopia in horses.
