Abstract:
OBJECTIVESTo study residual fraction (RF) in the bladder outlet obstruction (BOO) resulting from benign prostatic hyperplasia (BPH).
METHODSFifty adult outpatients with BPH were evaluated. With ultrasound and uroflowmetry, prevoid volume (PV) and postvoid residual volume (PRV) and peak flow rate (Qmax) were determined. Linear dependence analysis of RF and Qmax, PRV and Qmax were conducted.
RESULTSThe coefficient between RF and Qmax showed extremely negative correlation(r = -0.3859, P < 0.01). Also, PRV and Qmax showed significant negative correlation (r = -0.2831, P < 0.05).
CONCLUSIONSThe greater the RF, the more serious the BOO, the poorer potency of bladder. It is recommended that RF be used as a good supplement to PVR in the routine non-invasive evaluation of BOO caused by BPH.
