Objectives To evaluate the clinical efficacy of transurethral resection of the prostate on nocturia and sleep disorders in patients with lower urinary tract symptoms suggestive of benign prostatic obstruction. Methods A prospective multicenter study including lower urinary tract symptoms suggestive of benign prostatic obstruction patients with nocturia (twice or more) undergoing transurethral resection of the prostate was carried out. All patients were assessed using the I nternational P rostate S ymptom S core and the P ittsburgh S leep Q uality I ndex at baseline, and 6 months after transurethral resection of the prostate. Results Overall, 49 patients were included in the study. A total of 20 of them (41%) had a sleep disorder defined as a score of 5.5 or more on the P ittsburgh S leep Q uality I ndex global score. The nocturia score significantly correlated with component 4 of the P ittsburgh S leep Q uality I ndex (habitual sleep efficiency). Nocturia significantly decreased after transurethral resection of the prostate from 3.0 ± 1.2 to 1.9 ± 0.8, whereas the global P ittsburgh S leep Q uality I ndex score did not. In 20 patients with a sleep disorder before transurethral resection of the prostate, subjective sleep quality (component 1) and habitual sleep efficiency (component 4) significantly decreased after transurethral resection of the prostate, but this was not the case for the global P ittsburgh S leep Q uality I ndex score. In 16 patients with a persistent sleep disorder after transurethral resection of the prostate, I nternational P rostate S ymptom S core, voiding and storage symptoms score were higher than those of patients without a sleep disorder, although the nocturia score improved equivalently in both groups. Conclusions Transurethral resection of the prostate diminishes nocturnal urinary frequency and partly improves sleep quality in patients with nocturia and lower urinary tract symptoms suggestive of benign prostatic obstruction. A persistent sleep disorder after transurethral resection of the prostate is associated with persistent voiding and storage symptoms.
