Nephroureterectomy and ureteroneocystostomy in an alpaca with bilateral ectopic ureters diagnosed by computed tomographic excretory urography.

OBJECTIVE

To report diagnosis and treatment of urinary incontinence in a female Huacaya alpaca.

STUDY

DESIGN

Clinical case report.

ANIMALS: Female intact Huacaya alpaca (n = 1)

METHODS

Computed tomographic (CT) excretory urography and vaginourethrography were performed to diagnose the cause of urinary incontinence.

RESULTS

Bilateral ectopic ureters and left hydronephrosis and hydroureter were diagnosed. Left nephroureterectomy and right ureteroneocystostomy were performed with subsequent resolution of clinical signs. Pyelonephritis was identified by culture of the resected left kidney.

CONCLUSIONS

CT excretory urography was helpful in the diagnosis of bilateral ectopic ureters in an alpaca and provided information for surgical planning. Surgical repair by ureteroneocystostomy and unilateral nephroureterectomy was successful in resolving clinical signs.
