Bilateral ureterocystostomy to correct left ureteral atresia and right ureteral ectopia in an 8-month-old standardbred filly.
Abstract: To report the diagnosis and outcome after surgical correction of bilateral distal ureteral anomalies in a Standardbred filly. Methods: Clinical case report. Methods: An 8-month-old, 310 kg Standardbred filly with left ureteral atresia and right ureteral ectopia. Methods: The filly was admitted for evaluation of incontinence since birth and severe urine scalding of the hindquarters. Diagnosis was made by both direct (cystoscopy and vaginoscopy) and indirect (intravenous pyelography, ultrasonography, and scintigraphy) evaluation of the ureters and bladder. The filly had left ureteral atresia, hydronephrosis, and decreased left-sided renal function and right ureteral ectopia before surgery. Surgical correction was performed on the left by an end-to-side stapled anastomosis technique and on the right by a side-to-side hand-sewn anastomosis technique. Results: Surgical correction was successful. The filly had no postoperative complications and remained continent 18 months after surgery. Left renal function improved. Conclusions: Ureteral anomalies can be successfully repaired in larger (>300 kg) foals and some renal function may be restored after surgical correction. Conclusions: Scintigraphy should be considered in diagnosis of ureteral anomalies, assessing renal function, and determining prognosis for horses with hydronephrosis caused by ureteral ectopia and atresia.

The research discusses an 8-month-old standardbred filly diagnosed with ureteral atresia in the left side and ureteral ectopia in the right side. It showcases the successful surgical correction of the anomalies and the improvement in the foal’s renal function post-operation.
Background of the Case
- The study focuses on an 8-month-old, 310 kg Standardbred filly. The horse had been suffering from incontinence since birth along with severe urine scalding of the hindquarters.
- Following multiple evaluations and tests, both direct (cystoscopy and vaginoscopy) and indirect (intravenous pyelography, ultrasonography, and scintigraphy), she was diagnosed with left ureteral atresia and right ureteral ectopia.
- The left side also displayed signs of hydronephrosis and decreased renal function.
Surgical Procedure
- The surgeons performed two different techniques for correcting the anomalies in the left and right ureters respectively.
- For the left ureter, an end-to-side stapled anastomosis technique was used to correct the atresia.
- For the right ureter, the ectopia was corrected using a side-to-side hand-sewn anastomosis technique.
Post-operative Findings
- Post-surgery, the filly recovered without any complications. Her condition improved as she became continent again.
- 18 months after surgery, she remained symptom-free and showed signs of improved left renal function.
Conclusion of the Study
- The research concludes that ureteral anomalies can be successfully corrected in larger foals (>300 kg) through surgical correction.
- Furthermore, it shows that it’s possible to restore some renal function following surgery for such conditions.
- The paper also suggests the use of scintigraphy as a helpful tool for diagnosing ureteral anomalies, assessing renal function, and determining prognosis in equine medicine. Particularly for horses with hydronephrosis induced by ureteral ectopia and atresia.
