A new surgical method for penile girth enhancement

Area of Science:

• Veterinary Surgery
• Biomaterials Science
• Urology Research

Background:

• Developing effective surgical models is crucial for advancing research in penile augmentation.
• Existing models may have limitations regarding complications and recovery.
• A reliable animal model is needed for experimental investigation of penile implants.

Purpose of the Study:

• To develop a novel surgical model for penile girth enhancement in dogs.
• To evaluate the safety, efficacy, and recovery associated with the new surgical technique.
• To establish a foundation for experimental studies on penile implants using this model.

Main Methods:

• Utilized processed porcine pericardium and blood vessel walls as implant materials.
• Performed implantation into the penile bulb of Chinese Rural dogs, considering anatomical features.
• Measured penile girth pre- and post-operation, assessed erectile function, and monitored recovery and pathological changes using ultrasound.

Main Results:

• Achieved a significant increase in mean flaccid penile girth from 7.37 cm to 8.70 cm.
• Dogs exhibited normal mating behavior at 1 month post-operation without changes in mating time.
• Ultrasound successfully visualized implants and allowed measurement of implant-to-baculum distance.

Conclusions:

• The Chinese Rural dog serves as a promising animal model for penile girth enhancement surgery.
• Surgical implantation into the penile bulb offers minimal damage, rapid recovery, and high success rates.
• Ultrasonic examination provides objective data for assessing surgical outcomes in penile girth enhancement.
