Abstract: Objective To investigate influence of 45 degree semi-reclining position in cystometry in patients with benign prostatic hyPerplasia(BPH). Methods Patients with BPH were enrolled according to the inclusion and exclusion criteria. They were divided into two groups randomly by two stage cross-over design. Group A took the 45 degree semi-reclining position firstly then supine position, while group B used a reverse order.CMG parameters included volume of first sensation to void (FS), volume of first urge to void (FU), maximum cystometric capacity (MCC) and detrusor overactivity(DO). Results 45 degree semi-reclining position had no effect on volume of FS、volume of FU、MCC, and could increase the detection rate of DO(45 degree semi-reclining Position 37.21% vs. supine 11.63%,P=0.006). Conclusion 45 degree semi-reclining position may be used as a substitution for supine in FC.

Key words: Benign prostatic hyperplasia, Cystometry, 45 degree semi-reclining position
