Abstract
Objectives: To evaluate risk factors leading to corporal rupture after Collagenase Clostridium histolyticum (CCh). Peyronie's disease (PD) is a fibrotic condition of the penis characterized by abnormal plaque formation. Intralesional CCh is the only FDA approved medication for PD, however it can lead to corporal rupture, a potential surgical emergency.
Methods: We retrospectively reviewed medical records from Veterans diagnosed with PD who were under treatment with CCh using the Veterans Administration Informatics and Computing Infrastructure (VINCI). Using International Classification of Diseases and Current Procedural Terminology codes, we identified men who suffered a corporal rupture after CCh. Individual charts were reviewed to determine potential risk factors and events leading to corporal rupture.
Results: We identified 17,647 veterans who were diagnosed with PD, of which 8.7% (1,541) received at least one injection of CCh for PD. Of them, 0.7% (11/1,541) veterans suffered corporal rupture. Within these 11 patients, the median number of CCH injections was 6 with a median initial curvature of 35º. Fracture occurred at a median of 8 days after CCH injection. The majority of fractures were secondary to spontaneous erections or sexual intercourse. Finally, six patients had their fracture repaired surgically while the remaining were managed conservatively.
Conclusions: Most fractures occurred within 2 weeks of CCh injections and were associated with sexual intercourse and spontaneous morning erections.
