Abstract

We evaluated the effectiveness of sildenafil citrate on lower urinary system symptoms (LUTS) by using symptom score scales. We also evaluated whether or not the presence of asymptomatic inflammatory prostatitis had an effect on the alteration in the symptom scores. A total of 36 male patients were included in the study. For all the cases, 'International Prostate Symptom Score' (IPSS), 'National Health Institute Chronic Prostatitis Symptom Index' (NIH-CPSI) and 'International Index of Erectile Function' (IIEF-5) were investigated and the scores were calculated in the first visit. Sildenafil citrate was given for 30 days and at the second visit IPSS, NIH-CPSI and IIEF-5 scores were once more analyzed. Afterwards, the alterations of the scores between visits were statistically compared. Mean age of the 36 cases included in the study was 59.03±1.35. When the alterations in parameters of first visit and second visit were evaluated, we found a statistically significant increase in IIEF-5 and a statistically significant decrease in IPSS, IPSS-QOL (Quality of Life). In addition, when the cases were divided into two groups with and without asymptomatic inflammatory prostatitis, in the cases with asymptomatic inflammatory prostatitis, sildenafil citrate caused improvement only in ED, but had no effect on LUTS. Sildenafil citrate use in cases with LUTS and ED has an improving effect on LUTS as well as ED. However, in cases with asymptomatic inflammatory prostatitis, sildenafil citrate did not lead to an improvement in LUTS.
