Preparation and precautions for other special inspection items

1. Ultrasonography of pelvic organs requires the bladder to be filled in advance. Such as: bladder, uterus, prostate, ureter and other organs of ultrasound examination are required to be completed in the state of bladder filling.

Many examiners do not know how well the bladder should be filled, thinking that the urge to urinate is enough. In fact, the urge to urinate is not the best indicator for judging whether the bladder is full.

It is recommended to have a feeling of bulging in the lower abdomen. Some medical examiners feel bloated in the upper abdomen after drinking a lot of water. At this time, they cannot do an ultrasound examination immediately, because the water they just drank is in the gastrointestinal tract, so they have to wait for dozens of minutes, and then do the examination after the lower abdomen is bloated.

Generally speaking, it is necessary to drink 600~800 ml of water and wait for about 40 minutes before the bladder can be filled. For the ultrasound examination of pelvic organs, if it is done through the cavity, it is not necessary to fill the bladder.

2. Those who do colonoscopy need to clean the intestines under the guidance of the nurse in advance.
