The Cystocentesis model simulates a small animal abdominal wall and bladder to provide a realistic platform to develop and refine skills without requiring a live animal. Able to be used in conjunction with an ultrasound, real-world practices can be fully implemented. Included in the package is one base, two bladders, and a skin “sleeve”. The skin is designed to envelope the base so that students can practice multiple times by rotating it further around the base to expose an unused skin surface.
