    Abstract:
    OBJECTIVE: To evaluate the effect of daily low-dose tadalafil on erectile dysfunction (ED) induced by pelvic fracture urethral disruption (PFUD). METHODS: This study included 46 cases of PFUD-induced ED treated from Jan 2008 to Dec 2011. The patients were aged 33.9 +/- 7.2 years (range 25 -51 yr), and the interval between injury and treatment was 19.6 +/- 12.7 months (range 3 - 72 mo), all with normal erectile function before PFUD. Based on the nocturnal penile tumescence and rigidity (NPTR) recorded by erectometry without medication of phosphodiesterase type 5 inhibitor (PDE-5I), the patients were divided into an abnormal nocturnal erection group and a non-nocturnal erection group, and treated with tadalafil 10 mg once daily for 3 months. The therapeutic effect was evaluated by IIEF-5 scores and the rate of yes responses to questions 2 and 3 of the Sexual Encounter Profile (SEP). RESULTS: Totally 38 (82.6%) of the patients accomplished the treatment and follow-up, 26 (68.4%) in the abnormal nocturnal erection group and 12 (31.6%) in the non-nocturnal erection group. After 3 months of daily tadalafil treatment at 10 mg, the IIEF-5 scores were significantly improved in the abnormal nocturnal erection group than in the non-nocturnal erection group (P < 0.05), and the rate of yes responses to SEP2 and SEP3 was remarkably higher in the former than in the latter (76.9% vs 41.7% and 65.4% vs 25.0%, P < 0.05). CONCLUSIONS: Daily low-dose tadalafil can effectively improve the erectile function of PFUD-induced ED patients, particularly in those with nocturnal erection.
