Summary
Benign prostatic hypertrophy symptoms do not reliably predict abnormal urinary flowmetry. Both subjective symptoms and objective flowmetry data are essential for selecting prostatectomy candidates.
Area of Science:
- Urology
- Medical Diagnostics
Background:
- Benign prostatic hypertrophy (BPH) is a common condition in aging men.
- Assessing lower urinary tract symptoms (LUTS) and urinary flowmetry are crucial for diagnosis and treatment decisions.
Purpose of the Study:
- To evaluate the correlation between patient-reported symptoms and objective urinary flowmetry measurements in men with BPH.
- To determine if symptom complexes can accurately predict abnormal flowmetry findings.
Main Methods:
- Symptom assessment and uroflowmetry recordings were performed on 128 consecutive BPH patients.
- Patients were categorized into abnormal (peak flow rate ≥ 2 standard deviations from mean) and normal flowmetry groups.
- Statistical analysis, including discriminant analysis, was used to compare symptom prevalence and predictive value.
Main Results:
- Symptoms like poor stream and hesitancy were common in both normal and abnormal flowmetry groups.
- No significant correlation was found between peak flow rate and age.
- A symptom complex that accurately predicts abnormal peak flow rates could not be defined.
Conclusions:
- Symptomatology alone is insufficient to diagnose lower urinary tract obstruction.
- Objective flowmetry and subjective symptom reporting should be evaluated independently.
- Integrated assessment is vital for appropriate patient selection for prostatectomy.
