Simulation of the Endorectal Cooling Balloon Used to Protect Inflammation Tissue Damage During Prostatectomy Surgery

          It has been shown that the use of ECB can improve the recovery time of patients to regain continence and sexual function. The balloon is inserted into the rectum. The prostate, fat, muscle, and venous plexus are segmented based on individual patient’s MRI to build a patient-specific anatomic model. Then the bioheat equation is applied to calculate the distribution range of the cooling effect. The results may be used to adjust the setting of the cooling balloon for each patient to reach the desired temperature for optimal nerve protection during surgery.
