Summary

This study aims to identify which symptoms or test findings lead men with lower urinary tract symptoms (LUTS) to consider surgical treatment. Male patients who visit the outpatient clinic for LUTS will be asked whether they would consider surgery in the future if their symptoms persist. Along with this, symptom severity scores (IPSS), quality of life scores, and uroflowmetry measurements such as maximum flow rate (Qmax) and post-void residual volume (PVR) will be collected. The goal is to determine which factors are most strongly associated with a desire for surgery. This is an observational, non-interventional study.

Detailed description

This prospective observational study is designed to evaluate which clinical and uroflowmetry parameters are associated with a desire for surgical treatment in male patients presenting with lower urinary tract symptoms (LUTS). Participants will complete the International Prostate Symptom Score (IPSS) questionnaire, including the quality of life (QoL) item, and undergo uroflowmetry testing. Parameters such as maximum urinary flow rate (Qmax), post-void residual urine volume (PVR), and IPSS subdomain scores (e.g., weak stream, nocturia, urgency) will be analyzed. Patients will also be asked a standardized question regarding their surgical preference if their symptoms remain unchanged. The primary aim is to determine which symptoms or objective findings (e.g., specific IPSS items, reduced Qmax) are most predictive of a preference for surgical intervention. The study will help guide clinical decision-making by identifying symptom patterns or test results that are more likely to prompt patients to consider surgery. No therapeutic intervention will be performed as part of this study.
