The Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN) is developing a framework to understand lower urinary tract symptom subtypes. This research aims to improve diagnosis and treatment by focusing on urinary sensation and enhancing symptom measurement.
Area of Science:
- Urology
- Clinical Research
- Patient Outcomes
Background:
- Lower urinary tract symptoms (LUTS) lack comprehensive understanding and effective treatments.
- The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) established the Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN) to address these knowledge gaps.
Purpose of the Study:
- To identify and elucidate distinct subtypes of lower urinary tract symptoms.
- To enhance the accuracy and granularity of measuring patient-reported LUTS experiences.
- To foster collaboration and disseminate research findings to diverse stakeholders.
Main Methods:
- An observational cohort study is enrolling 1,000 patients with LUTS to characterize them extensively.
- Initial focus is on disorders of urinary sensation (e.g., urgency) and their underlying causes.
- Development and evaluation of a comprehensive set of self-report questionnaires for improved LUTS assessment.
Main Results:
- LURN has initiated the development of a foundational framework for the systematic study of LUTS subtypes.
- The network is prioritizing the domain of sensory experiences within LUTS.
Conclusions:
- The established framework guides the investigation into LUTS subtypes, starting with sensory aspects.
- Protocols are being created to refine symptom measurement and facilitate patient stratification.

Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
