Hi, Age 54, Male PSA 3.26, Prostate 46.5 cc, and shows normal echo texture. Pre void 330 cc, PVRU 19 cc. No calcifications are seen. Taking alfusin 10 mg for the past 1 and a half year. When not enough water is taken the stream is weak and dribbling, otherwise fine but after urination sensation of the bladder is not fully empty. Please suggest.
