“…Previous reports have indicated that the prevalence of nocturia among patients with OSAS (≥2 urinations per night) ranges from 40-50%. [17][18][19] The results of the present study are consistent with those findings and indicate that nocturia is a general symptom of moderate-to-severe OSAS. However, most patients (and even physicians) do not recognize the association between nocturia and OSAS.…”

Introduction: This study aimed to evaluate urination frequency among patients with obstructive sleep apnea syndrome (OSAS) and the effect of continuous positive airway pressure (CPAP) treatment.Methods: We evaluated 138 men with moderate-to-severe OSAS by using polysomnography. Urination status was assessed at baseline and three months using the International Prostate Symptom Score and Overactive Bladder Symptom Score. Nocturia was defined as ≥2 nighttime urinations and patients were classified into Group A (<50 years old with nocturia), Group B (≥50 years old with nocturia), and Group C (patients without nocturia). OSAS severity and other urinary symptoms were also evaluated.Results: Patients with nocturia exhibited more severe OSAS, compared to patients without nocturia (apnea-hypopnea index [AHI]: 52.0 vs. 44.7; p=0.021). Group A had the worst AHI, but did not have additional voiding symptoms, compared to Group B (p<0.001). The number of urinations was significantly correlated with OSAS severity in <50-year-old patients (p=0.013). CPAP reduced the number of urinations in Group A (75% of patients) and Group B (90% of patients). Patients with and without improved nocturia exhibited significant differences in their baseline OSAS severity (AHI: 53.7 vs. 37.3; p=0.042).Conclusions: OSAS severity was associated with the number of urinations in <50-year-old patients. CPAP decreased the nocturia frequency in 85% of patients with nocturia and was most effective in patients with severe AHI. However, additional studies should evaluate voiding volume in order to elucidate the mechanism of nocturia in patients with OSAS.

“…By doing this we will be able to direct the treatment toward the underlying disorder. It has been well documented that by treating patients with OSA with C-PAP, nocturia improves dramatically [7,[19][20][21]. In our study, we chose the Berlin Questionnaire as our screening tool because it has the highest sensitivity and specificity of all the questionnaires designed to screen for OSA [22].…”

“…It stands to reason that patients reporting nocturia to their physician should therefore also complete a Berlin Questionnaire. Treating OSA with CPAP has been demonstrated to reduce nocturnal urine production, with resultant decrease in episodes of nocturia, lending support to the consideration of identifying OSA in patients with nocturia [31,32]. Bladder hypoxia and nocturnal frequency An additional mechanism linking OSA and nocturia is bladder hypoxia [33].…”

Nocturia is a very common yet a highly underreported entity. Recently, there has been an increasing interest in nocturia because of its association with serious adverse health conditions such as diabetes, heart disease, elevated BMI, and mortality. Frequency volume charts are the cornerstone of initial assessment and are pivotal in determining the type of nocturia and associated causes. The diagnostic evaluation is aimed at clarifying the underlying cause: sleep disturbances, reduced bladder capacity (functional or extrinsic), and increased urine production (nocturnal or daily). Obstructive sleep apnea is an important cause of nocturnal polyuria and should always been considered. Management is focused on treating the underlying cause; a range of behavioral and pharmacologic options are available.
