In Zhen-Sheng Zhang, and coligue study;Pressure Makes Pleasure(39)
; in addition to achieving a uniform hydrostatic pressure to open up the external sphincter, they also asked patients to take a deep breath and comforted them by talking to reduce their pain when the scope was going to pass through the external urinary sphincter the and patient’s position during the procedure was dorsal lithotomy. The mean pain score on VAS was 2.95, 2.48, and 1.66 in group 1, 2, and 3, respectively. Compared to group 1 and group 2, the mean pain score was significantly lower in group 3 ( p < 0.001) and the mean pain score in group 2 was also statistically significantly lower than that in group 1 ( p = 0.045). In our study the operations were done while patients …show more content…
In this study, patients were allowed to see the screen if they wished. Patients were, however, unable to see whether the bag was being squeezed, although they were informed beforehand that the bag squeeze might make the discomfort better or worse.Although the patients were unaware of whether the bag was squeezed in this study, the cystoscopist was aware of which technique was used. This was because with the bag squeeze technique, the external urethral sphincter was often clearly visualized to open as the irrigating fluid bag was manually squeezed. Perhaps the slight increase in time allowed for squeezing and urethral distension was partly responsible for the reduced patient discomfort.This may affect the validity of the study.In our study these limitations were overcomed by the height of irrigation bag for every patient within each group is comparable, so the systemic error about irrigation pressure difference within each group could be avoided, and the result is objective and repeatable. In addition the irrigation pressure is almost unchanged once the height is fixed, so the conduction of the hydrostatic pressure is stable and uniform, consequently, patients may suffer less discomfort and the passage of the scope could be smoother in every step of this
