Randomized Controlled Trial Clinical Trial
Short-term sexual function after prostate brachytherapy.
Sexual function was evaluated in 34 patients with low-risk prostate cancer (PSA < or = 10, Gleason score < or = 6, clinical stage T1/T2) undergoing brachytherapy in a phase III prospective randomized trial comparing iodine-125 ((125)I) to palladium-103 ((103)Pd). The mean and median International Index of Erectile Function (IIEF) scores for the entire group were 14.2 and 16.5, respectively, and there was no difference between these scores when stratified by isotope. IIEF scores < 6, 6 to 11, and > or = 12 were recorded in 35% (12/34), 6% (2/34), and 59% (20/34) of patients, respectively. ⋯ All four impotent patients who used sildenafil responded favorably. With a median follow-up of 13 months, 65% of patients undergoing prostate brachytherapy maintained sexual function without pharmacologic support. Including sildenafil responses, 76.5% of patients sustained erections sufficient for sexual intercourse.
