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.

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.

Inclusion Criteria:

• Male patients aged 40 years and older
• Presenting with lower urinary tract symptoms (LUTS)
• Able to complete the IPSS questionnaire
• Undergoing uroflowmetry as part of routine evaluation
• Able and willing to provide informed consent

Exclusion Criteria:

• History of urological surgery (e.g., TURP, HoLEP, radical prostatectomy)
• Presence of known prostate or bladder cancer
• Active urinary tract infection at the time of evaluation
• Neurological conditions affecting voiding (e.g., Parkinson's disease, spinal cord injury)
• Inability to perform uroflowmetry or incomplete IPSS data

The study population includes adult male patients aged 40 years and older who present to the urology outpatient clinic with lower urinary tract symptoms (LUTS). All participants will complete the IPSS questionnaire and undergo uroflowmetry testing. Patients will be asked about their willingness to consider surgical treatment if their symptoms persist. No treatment or intervention will be administered as part of the study.

This study does not plan to publicly share individual participant data (IPD). However, de-identified data may be shared upon reasonable scientific request for academic or research purposes. Such requests will be evaluated on a case-by-case basis and may require institutional ethics approval and a data use agreement.
