Videourodynamic analysis in men with lower urinary tract symptoms: Correlation between age and prostate size with lower urinary tract dysfunction
Objectives: Lower urinary tract symptoms (LUTS) are highly prevalent in aging men. In this study we examined the relationship between age, total prostate volume (TPV), and videourodynamic study findings. Methods: We retrospectively analyzed a total of 971 men ≥ 40 years of age referred to us for inv...

| description | Objectives: Lower urinary tract symptoms (LUTS) are highly prevalent in aging men. In this study we examined the relationship between age, total prostate volume (TPV), and videourodynamic study findings.
Methods: We retrospectively analyzed a total of 971 men ≥ 40 years of age referred to us for investigation of LUTS. We analyzed the distribution of the different videourodynamic study diagnoses in male LUTS by correlating their age and prostate size.
Results: The most common diagnosis in the bladder outlet obstruction (BOO) group differed significantly by age and poor relaxation of the external sphincter (PRES) in those aged < 50 years; bladder neck dysfunction in those aged 50–69 years, and benign prostatic obstruction in those ≥ 60 years. Detrusor overactivity was the most common diagnosis in all ages in the bladder dysfunction group, and the cases of hyperactivity with impaired contractility (DHIC) increased with age. In patients < 50 years of age, PRES was the most common diagnosis in the BOO group in both those with small prostates (total prostate volume ≤ 40 mL) and large prostates (total prostate volume > 40 mL). In patients aged 50–69 years, the most common diagnosis in those with BOO and a small prostate was bladder neck dysfunction, and that in those with BOO and a large prostate was benign prostatic obstruction. Similar results were observed in patients aged ≥ 70 years. In all age groups, the majority of patients with detrusor overactivity, hypersensitive bladder, detrusor underactivity, and DHIC had a small prostate.
Conclusion: In male LUTS, the diagnoses in the BOO group differed by age and prostate volume. In young patients with BOO, the leading diagnosis was PRES, and the contribution of prostate volume to BOO increased with age. As age increased, the bladder function became more complex with an increased percentage of patients with DHIC. Both bladder outlet and bladder functions were affected by age. |
