Summary

Two geldings with haematuria and 6 stallions with haemospermia presented for evaluation between 2003 and 2011 to the Iowa State University Lloyd Veterinary Medical Center. Both geldings presented for haemorrhage at the end of urination. All stallions presented for evaluation of infertility following natural service or artificial insemination that was related to haemospermia. Urethroscopy identified a urethral defect in all 8 horses. Both geldings possessed a urethral rent. One stallion possessed a urethral varicosity while the remaining 5 possessed a urethral rent. Two geldings and 2 stallions received only laser treatment. The remaining 4 stallions received concurrent laser treatment with a temporary subischial incision (TSI) into the corpus spongiosum penis. All 6 stallions received 8 weeks of sexual rest after the completion of the surgical/laser treatment. Laser treatment alone was successful in resolving haematuria in one of 2 geldings. In the stallion group, all 4 horses with a urethral rent receiving laser treatment concurrent with a TSI resolved haemospermia. Of the remaining stallions, one with a urethral varicosity resolved clinical signs with only laser treatment and one stallion with a urethral rent received only laser treatment and haemospermia recurred. We conclude that laser treatment of a urethral rent in geldings can result in resolution of haematuria. Laser treatment used in combination with a TSI may result in improved success when compared to surgery alone. Laser treatment alone can result in resolution of a urethral varicosity.
