A comparison of different oral therapies versus no treatment for erectile dysfunction in 196 radical nerve-sparing radical prostatectomy patients

摘要

We retrospectively analyzed the effects on the erectile function (EF) of no treatment (NT), and an oral therapy (OT; on-demand therapy (OD) or a regimented rehabilitation (RR) program with phosphodiesterase type 5 inhibitors (PDE5-Is)), in a cohort of 196 consecutive patients following nerve-sparing radical retropubic prostatectomy (NSRRP). Patients undergoing bilateral NSRRP (BP; n=147) and unilateral NSRRP (UP; n=49), chose between OT (PDE5-Is OD or RR program) and NT. Patients who chose OD therapy received PDE5-Is (100?mg sildenafil, 20?mg tadalafil and vardenafil), whereas patients who chose the RR program received 100?mg sildenafil or 20?mg vardenafil three times a week, or 20?mg tadalafil twice a week at bedtime. The t-test for unpaired data and Fisher test were used for univariate analyses, logistic regression multivariate analysis was used to test the accuracy of available variables to predict EF recovery after radical prostatectomy. Potency rates were significantly correlated with the surgical technique and with OT when compared to NT (PP=NS). Early OT with PDE5-Is (OD or RR program) was superior to NT in recovery of EF in NSRRP. Furthermore, an RR program with PDE5-Is did not appear to be superior to OD therapy.
