PURPOSE: Penile fracture is a traumatic injury of the tunica albuginea of the corpus cavernosum during the erectile state. The aims of this study were to evaluate whether the differences of clinical manifestations according to age is present or not in the patients with penile fracture. MATERIALS AND METHODS: This study included 52 patients that were admitted to the department of urology after being diagnosed with penile fracture. History taking, physical examination, radiographic study, and operation were performed as needed. We divided patients into two groups on the basis of 40 years old, and we compared clinical manifestations and operative findings between the two groups. RESULTS: The mean age of patients was 41.4, and the most common cause of injury was sexual intercourse in both groups, but the elapsed time from the injury to arrival at hospital was longer in the young age group than the middle age group (p<0.05). In the aspect of the rupture of tunica albuginea, injury to the right and proximal part of the penis was most common in both groups. Transverse rupture was more prevalent, and the length of the rupture line was also longer in the middle and old age group (p<0.05). CONCLUSIONS: This study supports that sexual intercourse is the most common cause of penile fracture in our country, and the majority of both groups have rupture of tunica albuginea at the right proximal part of the penis. However, the degree of rupture is severe, and elapsed time from the injury to arrival at hospital was relatively shorter in the middle and old age group than the young age group.
