OBJECTIVE: We developed a new surgical model of penile girth enhancement in dog,
with minimal damage, fewer complications, and high success rate, to enable the
experimental investigation of penile implants. METHODS: We obtained materials for
penile girth enhancement by processing the pericardium and blood vessel wall
collected from pigs. Incisions were made at the penile bulb for the implantation
of the materials, and facilitate observation and data collection, based on the
anatomical features of dog's penis. We measured the girth of the flaccid penis
before and after the operation, and erectile function at 1-month postoperation.
In addition to evaluation of recovery from the incision and local pathological
changes, ultrasonic examination was performed to monitor the long-term changes
associated with implantation. RESULTS: The mean girth of the flaccid penis
significantly increased from 7.37±0.40 cm before the operation, to 8.70±0.56 cm
postoperation. Dogs resumed normal mating at 1 month after the operation, without
any significant change in the mating time. Ultrasonic examination clearly
illustrated the implants, and helped in the measurement of the distance between
the materials and the baculum. CONCLUSION: Chinese Rural dog is a promising
animal model for penile girth enhancement surgery. The findings demonstrated that
surgical implantation into penile bulb was associated with less damage, faster
postoperative recovery, and higher success. For the first time, ultrasonic
examination provided objective data on the surgical outcomes of penile girth
enhancement.
