AbstrAct Aim: To evaluate diagnosis and prediction of ED by using nocturnal penile tumescence, rigidity (NPTR) combined with audiovisual sexual stimulation (AVSS) and Sildenafil. Materials and Methods: Multicentre study was conducted. Penile rigidity was recorded by NPTR test during 1 hour. AVSS test was performed in 3 steps; First step involved no medical treatment whereas the 2nd and 3rd steps involved 50mg and 100mg Sildenafil, respectively. NPTR test combined with AVSS and Sildenafil was accepted as positive if sufficient erection was observed in any step (Group 1, n=33), if vice versa the patient was included in Group 2 (n=19). Then, each patient underwent intracavernosal injection test (ICE), penile Doppler ultrasonography (PDU), and NPTR. results: Mean age was 55±7.4 years. AVSS-NPTR with Sildenafil was positive in 33 (63.5%) patients (Group1) and negative (Group 2) in 19 (36.5%) patients. In Group 1, sufficient erection was achieved in 5 (9.6%), in terms of 18 (34.6%) and 10 (19.2%) patients at the 1st and 2nd steps, respectively. AVSS test showed similar diagnostic efficacy with only NPT (p=0.02) and ICE (p<0.001). conclusions: AVSS-NPTR with Sildenafil can be strong candidate for a practical in evaluation of ED and its treatment effectivity.
