correlation between transition zone index, uroflowmetry, residual urine, and other clinical parameters in patients with symptomatic benign prostatic hyperplasia

ABSTRACT

This study was conducted on a series of 88 consecutive patients with lower urinary tract symptoms suggestive of BPH. They were subjected to history taking [including the IPSS- symptom scores], physical examination [including digital rectal examination], biochemistry [including PSA], urinalysis and culture, urine cytology and uroflowmetry. The total prostate volume and the transition zone [TZ] volume were assessed by transrectal ultrasound using the ellipsoid formula. There were very slight differences between the correlation of the total prostate volume, transition zone volume and transition zone index and the clinical parameters. The estimation of the total prostate volume by TRUS proved to be a reasonable way to obtain the required information about prostate size and measuring TZ volume and the calculation of TZ index gave a limited additional value
