🔍 Key Findings
- Modified preputial urethrostomy without penile amputation was successfully performed in 4 male dogs with urethral stenosis or trauma.
- The technique involved anastomosis of the pelvic urethra to the preputial mucosa via caudal celiotomy, avoiding perineal urethrostomy complications.
- No cases of skin scalding or stoma stenosis were reported during short- and long-term follow-up.
- Two dogs developed mild urinary incontinence, particularly when excited; one improved with phenylpropanolamine.
- The approach preserved local anatomy, avoiding penile amputation, osteotomies, and preputial dissection.
- Postoperative urinary catheterization was used to protect the anastomosis, although optimal duration remains debated.
- Surgical access via the linea alba minimized tension at the anastomosis site and avoided complications from paramedian approaches.
- This technique may serve as a viable alternative to prepubic urethrostomy, reducing urine-related skin complications and improving cosmetic outcome.
