The aim of this report is to describe a new methodology to successfully treat stallions diagnosed with urethral rent. Four stallions of ages ranging from 7 to 12 years (median 9) with hemospermia were admitted for clinical evaluation, breeding soundness examination, and urethroscopy for inspection of the urethra and vesicular glands. Once the presence of urethral rent was identified and/or other sources of hemorrhage were excluded, a topical treatment was performed with 4% Policresulen solution (Albocresil). The treatment was carried out by infusing 100 mL of the solution into the lumen of the urethra through a catheter placed up to the region of the ischial arch. This procedure was repeated once daily, or at 48 hours intervals, resulting in a total of 4–7 infusions. In all cases, chemical cauterization was efficient in the healing of the urethral rent. However, due to masturbation during treatment, one animal did not completely heal, and the treatment with the Policresulen was prolonged. It is believed that the low pH of the solution resulted in urethritis, which was treated with systemic therapy of antibiotic and anti-inflammatory nonsteroidal. Topical treatment with 4% Policresulen was found to be efficient in the chemical cauterization of urethral rent in stallions. This treatment was efficient, practical, less invasive, and less costly than the alternative of surgical methods, which are more invasive and require longer recovery time of the animal. However, sexual rest and the elimination of sexual stimuli from the environment are essential management in association with this therapeutic method.
