Pressure-flow studies: An evaluation of within-testing reproducibility?validity of the measured parameters

Correlation between the presence of inguinal hernia and the intensity of lower urinary tract symptoms

“…There are limited data regarding the normal residual urine volume in asymptomatic patients and until now no consensus has been reached to the relationship between residual urine, BOO and detrusor underactivity. In addition, the residual urine volume can vary over time especially in elderly patients 17 .…”

Variability of pressure-flow studies in men with lower urinary tract symptoms

“…Variability of PFS outcomes has been the subject of previous studies [van de Beek et al, 1992;Hansen et al, 1997;Madsen et al, 1995;Rosier et al, 1995;Tammela, 1999;Witjes et al, 1996]. Variability of PFS outcomes has been the subject of previous studies [van de Beek et al, 1992;Hansen et al, 1997;Madsen et al, 1995;Rosier et al, 1995;Tammela, 1999;Witjes et al, 1996].…”

Intra- and inter-investigator variation in the analysis of pressure-flow studies in men with lower urinary tract symptoms

“…In a recent study performed in our clinic, we found a moderate intra-patient reproducibility of PFS [Sonke et al, 1999]. However, better results concerning reproducibility were reported earlier [vd Beek et al, 1992;Madsen et al, 1995;Rosier et al, 1995;Hansen et al, 1997Hansen et al, , 1999. A distinction should be made between reproducibility within one session of two PFS and reproducibility of two PFS performed at different occasions.…”
