Impact of intra-urethra1 catheter on urof1ow rate in pressure-f1ow study / 中华泌尿外科杂志

ABSTRACT

0.05) respectively.The maximum free uroflow rate was (9.55?4.10)ml/s,and the maximum catheter's uroflow rate was (7.32? 3.28)ml/s(P=0.000).The difference of uroflometry between two voids was (2.22?3.07)ml/s.Paired t-test showed that there was significant difference between the maximum free uroflow rate and maximum catheter's uroflow rate (P0.05) when LPURR lie in Ⅱ,Ⅴ～Ⅵ grade. Conclusions 7 F urethral catheter appeared to have a significant impact on maximum uroflow rate.
