An unusual case of an ectopic ureter and hydronephrosis in a 9 month female alpaca with persistent complain of incontinence is reported. Hydronephrosis and hydroureter was evident on ultrasonographic examination. An intravenous pyelogram and excretory urogram was performed to assess kidney function, as well as document the possibility of an ectopic ureter. The right kidney function and ureter were determined normal. Unilateral left nephrectomy and ureterectomy was performed through a caudal ventral midline celiotomy. The alpaca began feeding soon after recovery and had no significant difficulties over the course of the recovery period. On follow-up a year after surgery, the owner reported that the alpaca was well and had normal growth. No episodes of incontinence were observed.
