A modified perineal urethrostomy was performed in 14 male cats with partial
or complete urethral obstruction. Follow-up information was available for
2 to 18 months. by use of this method, the preputial tissues were preserved
, and the penile urethra was anastomosed to the preputial mucose to enlarge
and lengthen the urethra. Urine flow was reestablished in all cats without
evidence of urethral stenosis or other major complications. Appearance of
the perineal region and prepuce was not substantially altered.
