RESUMO
Can transitional zone index [the ratio belween transition zone volume and total prostate volume as measured by transrectal ultrasound] serve as a better proxy for clinical prostatism? We prospectively evaluated 60 patients with symptomatic BPH ;according to symptoms [AUA symptom score] peak urine flow [Q max] ;and detrusor pressure at peak urine flow, Transrectal ultrasound [TRUS] measurement of the prostate volume and the transition zone [TZ] volume was done and transition zone index [TZI] was calculated. We found that prostate volume insignificantly correlated with BPH parameters. TZI volume highly significantly and strongly correlated with BPH parameters and may serve as a useful proxy for evaluating worsening obstruction in BPH Key Words: Prostate. Prostate Hypenrophy
