Symptoms, prostate volume, and urodynamic findings in elderly male volunteers without and with LUTS and in patients with LUTS suggestive of benign prostatic hyperplasia

Objectives. To estimate the differences in symptoms, prostate volume, and urodynamic variables of symptom-free elderly volunteers, volunteers with lower urinary tract symptoms (LUTS), and urologic patients with LUTS suggestive of benign prostatic hyperplasia. Methods. The study included 14 male volunteers without LUTS, 17 male volunteers with LUTS, and 565 urologic patients with LUTS who met the criteria of the International Consensus Committee on Benign Prostatic Hyperplasia. They were older than 50 years, they voided more than 150 mL during free uroflowmetry, their residual volume and prostate volume were estimated, and their American Urological Association symptom scores were collected. All men were also evaluated by urodynamic studies. Results. The prostate volume, residual volume, urethral resistance factor, and symptom scores were significantly lower and the maximal free flow rate and effective capacity significantly higher in the symptom-free volunteers than in the volunteers and patients with LUTS. Except for prostate volume, the variables in volunteers with LUTS closely approximated those of the patients with LUTS. The volunteers with LUTS had a smaller prostate volume than did the patients with LUTS. Nevertheless, the maximal free flow rate, symptoms, degree of obstruction, and prevalence of residual volume did not differ between the two groups. Men with an unstable bladder were present in all groups. Conclusions. Symptom-free volunteers had smaller prostate volumes, less residual volume, lower symptom scores, a lower urethral resistance factor, a higher maximal free flow rate, and a higher effective capacity than those with LUTS. Except for a smaller prostate volume, the findings in the volunteers with LUTS closely approximated those of the urologic patients with LUTS. UROLOGY 58: 966-971, 2001.

Data from frequency-volume charts versus symptom scores and quality of life score in men with lower urinary tract symptoms due to benign prostatic hyperplasia

Objective: The aim is to study the relations between reported data on frequency-volume charts and the American Urological Association (AUA) symptom scores and quality of life score. Methods: Males with lower urinary tract symptoms due to benign prostatic hyperplasia (BPH), were consecutively included in the study if they met the criteria of the International Consensus Committee on BPH, they voided >150 ml during uroflowmetry, residual volume and prostate size were estimated and frequency-volume charts were completed correctly. From the frequency-volume charts, voiding habits and fluid intake in the daytime and at night were evaluated. Results: In the included 160 men no correlation was found between total urine production at night or in the daytime and symptom index or quality of life score. Nycturia was correlated with symptom index, but surprisingly not with quality of life score. Small voided volumes at night and in daytime are attended by high symptom index and high quality of life score (= low quality of life). Diuria has a high impact on symptom index and quality of life score. Men who completed frequency-volume charts during 3 or more daytime periods (68%) had a significantly higher symptom index than those who completed only 1 or 2 daytime periods (32%). Conclusions: High diuria, and small voided volumes at night and in daytime contribute significantly to high symptoms and low quality of life. Nycturia correlated with AUA symptom index but surprisingly not with quality of life score. Copyright (C) 2001 S. Karger AG, Basel

Analysis and reliability of data from 24-hour frequency-volume charts in men with lower urinary tract symptoms due to benign prostatic hyperplasia

Objectives: The aims of this study were to analyse the data from frequency-volume charts and to study the reliability of these charts in men with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH), Methods: Males with LUTS due to BPH were consecutively included in the study if they met the criteria of the International Consensus Committee on BPH, voided more than 150 ml during uroflowmetry, residual volume and prostate size were estimated and frequency-volume charts were completed correctly. From the frequency-volume charts, voiding habits and fluid intake were evaluated. Results: 160 patients could be included. Another 28 patients who met all other criteria did not complete the frequency-volume charts correctly. Agreement exists between reported voided volumes in the literature and those found by us. We found a significant correlation (p Conclusion: Frequency-volume charts are reliable in the investigation of patients with LUTS due to BPH. Reporting on frequency-volume charts during just 24 h is sufficient to gain insight into their voiding habits during normal daily life. Copyright (C) 2000 S. Karger AG, Basel
