Absolute ethanol is a widely used embolization substance in human beings but has no definite indication in animals. In this study, three dogs with a unilateral ectopic ureter were treated by renal embolization with sterile absolute ethanol using a previously described technique. Immediate cessation of urinary incontinence was observed in two cases, while the third case improved but showed persistent urinary incontinence that was ascribed to vesicourethral sphincter incompetence. Post-interventional complications were the same as those encountered with the more conventional surgical techniques. Other possible applications of embolization procedures with absolute ethanol are briefly discussed.
