[Clinical experience of simultaneous fiber-urethrocystoscopy and cystometry recording]

We performed fiber-urethroscopy and cystometry recording simultaneously in 15 male patients. Fifteen patients were consisted of 12 complaining of micturition difficulty (such as BPH, NB, BNS) and 3 normal control. Fiberscope, Olympus CYF-1 and BF3C10, and cystometry were connected the DISA system. Firstly, we insert fiberscope from the urethra to bladder careful, and then cystometry recording using carbon dioxide gas started under direct vision of fiberscope. We compared cystometrical parameters based on our original method to these on conventional one. There were slight statistical significances in the pressure at the first desire to void and the maximum desire to void. But these differences as well as the frequently and the size of uninhibited contraction were not induced by the caliber of the urethroscopy. In conclusion, cystometric recording and urethroscopic observation using fiberscope are simultaneously carried out safely without reducing their diagnostic accuracy.
