Nocturia in interstitial cystitis/painful bladder syndrome

Area of Science:

• Urology
• Pain Management
• Patient-Reported Outcomes

Background:

• Interstitial cystitis/painful bladder syndrome (IC/PBS) is a chronic condition characterized by bladder pain and urinary urgency.
• Nocturia, or nighttime urination, is a common and often debilitating symptom in patients with IC/PBS.
• The specific contribution of pain and urgency to nocturia in IC/PBS remains incompletely understood.

Purpose of the Study:

• To investigate the roles of pain and urinary urgency in the development of nocturia among individuals diagnosed with IC/PBS.
• To elucidate the relationship between the severity of nocturia and the presence and intensity of pain and urgency in IC/PBS patients.

Main Methods:

• A longitudinal study design was employed, focusing on incident cases of IC/PBS.
• Multivariate analyses were used to assess the associations between nocturia, pain, and urgency.
• Direct patient questioning explored the primary reasons for nighttime awakenings in IC/PBS.

Main Results:

• Urinary urgency was significantly associated with both the presence and severity of nocturia.
• Bladder pain severity was directly correlated with the severity of nocturia.
• Patients reported that bladder pain awakens them directly (minority) or indirectly by causing urgency (majority).

Conclusions:

• Both urinary urgency and bladder pain are implicated as causal factors in nocturia for patients with IC/PBS.
• These findings suggest that managing pain and urgency may be crucial for alleviating nocturia in IC/PBS.
• The study highlights a dual role for bladder pain in nocturia, acting both directly and through the generation of urgency.
