Abstract: In a method of treating a patient having diffuse plaque and/or a plaque mass associated with Peyronie's disease in a penile region, a battery of tests is performed to quantify an initial state of parameters associated with Peyronie's disease in the patient. Low intensity shock wave therapy is applied to the plaque mass in the penile region, thereby softening the plaque mass and disrupting any calcification in the plaque mass. Carbon dioxide is injected into the plaque mass. The battery of tests is repeated to quantify a current state of parameters associated with Peyronie's disease in the patient and the current state is compared to the initial state. The aforementioned treatment steps are repeated until the current state differs from the initial state by at least a predetermined amount.
