[Conventional and ambulatory urodynamic study on patients with chronic prostatitis syndrome]

To study the urodynamic findings of chronic prostatitis syndrome (CPS), 58 patients with chronic prostatitis and prostatodynia were subjected to the urodynamic investigation that included conventional medium filling urodynamic (CMG) tests (urethral pressure profile, filling cystometry, voiding pressure-flow study) and ambulatory urodynamic monitoring (AM) by using Dantec Menuet and Urodec 500 AM system. 55 BPH patients and 20 normal men were taken as control groups. CPS patients had function bladder outflow obstruction (FBOO). FBOO resulted in the detrusor instable (DIS, 12.1%), detrusor-sphincter dysnergia (DSD, 100%) and detrusor dysconstractility (DDC, 6.9%), and resulted in clinical symptoms. FBOO resulted from the urethal sphincter spasm and DSD.
