Mean age 56.7 (SD: 9.61) years. Mean basal penile curvature 59.37o (SD: 18.26). The mean pain value related to the procedure measured after the first injection of the first cycle (without anaesthesia) was 5.4 (SD: 2.13), while after the second injection (with anaesthesia) was 2.5 (SD: 1.92), (p < .001). The treatment was more painful in patients with dorsal plaques (mean:6.2) than in patients with lateral plaques (mean: 4.35) (p = .01).

Abstract

The intraplaque injection of collagenase from Clostridium Histolyticum (CCH) was established as an effective therapeutic alternative for selected patients with Peyronie's disease (PD). There is no consensus on the use of pre-procedure anaesthesia. The aim of this pilot study was to assess the efficacy and safety of dorsal penile block before CCH injections in reducing procedure related pain. The treatment protocol described in the IMPRESS trials was adopted. The first injection of the first cycle was given without anaesthesia, while the second after penile block. After the administration of each injection, the pain related to the procedure was evaluated with the Wong-Baker-FACES(R)-Pain-Rating-Scale. Thirty patients were included. Mean age 56.7 (SD: 9.61) years. Mean basal penile curvature 59.37o (SD: 18.26). The mean pain value related to the procedure measured after the first injection of the first cycle (without anaesthesia) was 5.4 (SD: 2.13), while after the second injection (with anaesthesia) was 2.5 (SD: 1.92), (p < .001). The treatment was more painful in patients with dorsal plaques (mean:6.2) than in patients with lateral plaques (mean: 4.35) (p = .01). We can conclude that penile block before CCH injection in patients with PD seems an effective and safe measure to decrease the pain related to the procedure.
