What this trial studies

This observational study investigates the relationship between obstructive sleep apnea (OSA) and nocturia in patients diagnosed with OSA. Participants will undergo routine examinations and complete voiding diaries over a 48-hour period to assess urinary patterns. The primary aim is to identify any correlations between specific parameters of sleep apnea and the occurrence of nocturia, potentially shedding light on this common yet often overlooked symptom in OSA patients.

Why it matters

Potential benefit: If successful, this study could enhance understanding of nocturia in patients with obstructive sleep apnea, leading to improved management strategies.

How similar studies have gone: While the relationship between sleep apnea and nocturia has been explored in some studies, this specific observational approach is relatively novel.
