Summary
Aims
To explore and objectify the impact of diuresis on the presence of daytime and nighttime LUTS, and associated bother.
Methods
Participants (healthy volunteers and patients referred to our hospital for a urologic consultation) were asked to complete a 72‐hour bladder diary and also had to fill in a Likert scale (0: no bother; 10: maximal bother) to evaluate the LUTS‐associated bother during daytime and nighttime. Three groups were defined: no/mild bother (Bother ≤2), moderate bother (3 ≤ Bother ≤ 6), and strong bother (Bother ≥7). Questionnaires in order to assess LUTS (ICIQ MLUTS and ICIQ FLUTS), quality of life (SF‐36, NqOL), and quality of sleep (PSQI) were completed.
Results
During daytime and nighttime, the study of participants with a strong bother associated with LUTS revealed a statistically significant higher fluid intake than those without bother (1640 mL vs 1800 mL during daytime, P = 0.007). Also, those with higher diuresis rate had more bother related to LUTS than the others (71.3 mL/h in group 1 vs 87.3 mL/h in group 3 (P < 0.001) during daytime). As might be expected, lower urinary tract such as bladder, for example, studied through maximal voided volume does play a role. The lower the maximal voided volume is, the more bother the participants described.
Conclusions
This study pointed out the implication of diuresis in bother related to LUTS. Our findings showed that there was an increase in bother by 1 when diuresis increased by 100 mL/h.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
