N2 - Purpose: To investigate improvement in nocturia and nocturnal polyuria in nocturnal polyuria patients after silodosin administration by using a 3-day frequency volume chart. Methods: This was a prospective multicenter study. We enrolled nocturnal polyuria patients (nocturnal polyuria index [NPi] > 0.33), aged ≥60 years, diagnosed with the 3-day frequency volume charts of patients with benign prostatic hyperplasia taking a-blockers. Of the 54 patients, 30 (55.6%) completed the study according to the study protocol (per-protocol group), and 24 dropped out (dropout group). Results: Of the 24 patients in the dropout group, 5 withdrew consent due to side effects or lack of efficacy, 7 were lost to follow- up at 4 weeks, 8 were lost to follow-up at 12 weeks, and 4 dropped out due to failure to complete 3-day frequency volume charts at 12 weeks. In the per-protocol group, there was significant improvement in the International Prostate Symptom Score (IPSS), especially question numbers 1, 3, 4, 5, 6, 7, and the quality of life question (P = 0.001, P = 0.007, P < 0.001, P = 0.003, P = 0.049, P < 0.001, and P < 0.001, respectively). The Leeds sleep evaluation questionnaire (LSEQ) score for the sleep question improved from 64.36 to 70.43 (P = 0.039). The NPi reduced from 0.4005 to 0.3573 (P = 0.027); however, in many cases, there was no improvement in nocturnal polyuria itself. In intention-to-treat analysis, there were significant improvements in IPSS and LSEQ in 45 patients. Conclusions: In elderly nocturnal polyuria patients, silodosin monotherapy exhibits good efficacy in improving nocturia and nocturnal polyuria; however, the mean NPi was still > 0.33. Considering the high dropout rate of our study due to no implementation of 3-day frequency volume charts, prospective and large-scale studies are needed to confirm our results.
