The Efficacy of Compression Stockings on Patients With Nocturia: A Single-Arm Pilot Study

Abstract

Objectives: Behavioral treatment for nocturia includes wearing compression stockings. However, a reading of the cited literature for evidence shows that there is not enough research data to support this recommendation, and it is controversial. The present study aimed to investigate and supplement evidence on the effects of wearing compression stockings during the daytime in patients with nocturia.Methods: This was a single-arm prospective study to investigate the effects of compression stockings on nocturia for four weeks. Patients were asked to record a frequency-volume chart and complete various questionnaires at baseline and after four weeks, and also provide feedback on treatment satisfaction. The primary endpoint was a change in night-time frequency in the frequency-volume chart from the baseline to the end of treatment.Results: Thirty-four patients (19 men and 15 women; age: 72.3 ± 12.6 years) were included. Two patients dropped out because of pain associated with wearing compression stockings and one due to a refusal to wear compression stockings every day. Therefore 31 patients were analyzed. In the frequency-volume chart, night-time and 24-hour frequencies significantly decreased by 0.5 and 1.1 episodes, respectively (P = 0.004 and P = 0.035, respectively). The hours of undisturbed sleep significantly increased by 0.8 h (P = 0.013). No significant differences were observed in nocturnal or 24-h urine volumes, the number of urgency or urinary incontinence episodes, the mean or maximum voided volume, the nocturnal polyuria index, or the first night-time voided volume. The total overactive bladder symptom score significantly decreased (P = 0.006). Significant reductions were also observed in all overactive bladder symptom score subscores, except for the daytime frequency score.Conclusion: The present results suggest the effectiveness of wearing compression stockings during the day was satisfactory in most patients with nocturia, and the treatment was safely continued in patients who experienced no pain when wearing the stockings. Based on the results of this study, we believe that it is worth considering as a treatment for nocturia.
