Phimosis is characterized as an inability to extrude the penis through the prepuce, typically due to narrowing of the preputial orifice. Causes have been described as congenital or acquired in canine and feline species. Acquired conditions are thought to commonly result from trauma, such as excessive grooming from the dam or redirected suckling behavior toward the prepuce of male littermates in orphaned animals, resulting in inflammation (A).
Type 1 phimosis was characterized by a narrowed preputial orifice along with swelling or outward ballooning of the prepuce due to urine pooling (B).
For Type 1 disease patients, a 360 degree opening was made, with care taken to prevent penile exposure from excessive enlargement (C).
Small gauge (5-0 to 7-0) absorbable suture was utilized in a simple interrupted pattern between the preputial mucosa and the skin (D).
Type 2 phimosis was characterized by a narrowed preputial orifice and penile-preputial adhesions (E).
For Type 2 disease patients, a tear drop incision was made midline into the penile urethra, and a penile urethrostomy was created (F).
Small gauge (5-0 to 7-0) absorbable suture was utilized in a simple interrupted pattern to complete suturing of the urethral mucosa and the skin (G).
