Detailed Description

Bidet is an electronic device spraying stream of the water for cleansing the anus and sometimes to aid defecation. It is widely used in Korea and Japan, with the flow rate (pressure) and temperature of water varying widely among the manufacturers. However, the effects of Bidet on anorectal function have not been studied in detail with regards to these variables.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The pressure before and after applying the bidet
Time Frame: after 1minute
After the anal resting pressure was stabilized at sitting position, water stream of the bidet was applied to anus for 1 minute under various settings of different pressures (4, 8, 16, 20 gram force, gf), temperatures (24oC vs. 38oC), types of stream (narrow vs. wide) (Total time for experiment at individual subject was about two hours)
after 1minute

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The temperature of rectum
Time Frame: after 1minute
The temperature probe was supposed to be placed in the rectum with manometry catheter and to prove the possibility of insertion of warm water into the rectum.
after 1minute
