Correlation between uroflowmetry, prostate volume, postvoid residue, and lower urinary tract symptoms as measured by the international prostate symptom score

Abstract

Objectives. To evaluate the relation between lower urinary tract symptoms (LUTS) as measured by the International Prostate Symptom Score (IPSS) and noninvasive objective parameters of lower urinary tract dysfunction. Methods. Eight hundred three consecutive patients with LUTS and/or benign prostatic hyperplasia were evaluated with IPSS, uroflowmetry, prostate volume estimation, and postvoiding residue measurement. The relations between these parameters were quantified by means of Spearman correlation coefficients. Results. Statistically significant but weak correlations were found between the IPSS and results of uroflowmetry and postvoiding residual urine. There was no correlation between the IPSS and results of prostate volume measurements. Conclusions. The correlation between objective noninvasive parameters of lower urinary tract dysfunction and LUTS is weak.

Correlation of sonographic prostate volume with international prostate symptom score in South Indian men

“…10 Another study by Tsukamoto et al showed that a change in IPSS was associated with a change in prostate volume, 11 whereas study by Agrawal et al, Sanjeev singla et al, Udeh et al, and Ezz et al showed no relationship between prostate size and IPSS score. 6,8,12,13 There was no correlation between the age and IPSS in our study, which is similar with Agrawal et al, but Bosch JL et 14 states that very weak correlation between the IPSS and age (r = 0.09, P = 0.04). There is lot of variations in the findings by different authors, but most of studies found no strong correlation between the IPSS and prostate volume.…”

Experience with Uroflowmetry in Evaluation of Lower Urinary Tract Symptoms in Patients with Benign Prostatic Hyperplasia

“…Hence, no correlation was found in between prostatic volume and IPSS. This data was further supported by other studies which were done by Ezz et al, on 803 patients [12].…”

Urodynamic studies in the surgical treatment of benign prostatic hyperplasia

“…At present, the most utilized method to confirm infravesical obstruction is the pressure / flow study (12)(13)(14)(15)(16). Urodynamics distinguish low flow secondary to hypoactivity of the detrusor from the low flow caused by obstruction.…”
