【科普视频】两分钟了解尿动力学检查

来源：泌尿科那点事儿

编者按

本期为大家分享欧洲泌尿外科学会视频——尿动力学检查，主要包括尿流率检测与膀胱内压检测，前者用于测量排尿时尿液的流动速率，后者用于检测膀胱空虚和充盈时膀胱内压的变化，从而了解储尿期和排尿期膀胱功能是否异常。同时附上英文资料，以供大家更好地学习、交流。

这部短片将通过尿动力学的检查为您介绍膀胱的作用。这些检查将带您了解储存尿液与排放尿液的器官，例如膀胱、尿道以及他们之间的连接组织，这些检查包括尿流率检测与膀胱内压检测。尿流率检测用于测量排尿时尿液的流动速率，膀胱内压检测用于检测膀胱充盈及膀胱空虚时是否正常。

本动画展示了常规尿动力学检查是如何进行的，医生通常会先进行尿流率检测，医生会要求患者在特制的私密便池内排尿，便池会测量患者的尿流，随后，医生用超声波检测患者膀胱是否已排空。若患者还需进行膀胱内压检测，医生会为患者实行局部麻醉，并将一根导管插入尿道中，另一根导 管插入直肠中，两根导 管可测量膀胱及腹腔的压力值，腹部的传感器可监测骨盆肌肉的活动，医生会通过导管为患者膀胱注入消毒过的液体，并要求患者咳嗽或用力，以测试膀胱反应，医生会检查是否有漏尿以及患者是否有尿意，膀胱注满液体后，医生会要求患者排尿，同时检测压力值。

膀胱内压检测结束后，医生会移除导管与传感器，检测结束后，医生会通知患者检测结果，制定后续医治方案。

English Subtitles

You are about to undergo a urodynamic study to investigate the function of your bladder.These tests will help evaluate the organs that store and pass urine, such as the bladder, urethra and tissue that connects them.Some of the tests include uroflowmetry and cystometry.Uroflowmetry is used to measure the rate of urine flow during urination.Cystometry is used to check whether the bladder is emptying and filling properly.

This animation shows how a typical urodynamic study is performed.Your doctor might begin with uroflowmetry.You will be asked to urinate on a special toilet in private.This toilet will measure the flow of your urine.Afterwards, an ultrasound of your bladder is made to see how well it emptied.If you have to undergo cystometry as well,a catheter will be inserted into your urethra after receiving a local anesthetic,then one more catheter is placed in your rectum.Both catheters measure the pressure in your bladder and your abdomen.Sensors on your abdomen monitor the activity of the pelvic muscles.Your doctor will fill your bladder with sterilized fluid using the catheter.You will be asked to cough or bear down to test your bladder reaction.Your doctor will check if there is any urine leakage and if you feel the need to urinate.When your bladder is full, you will be asked to urinate while the pressure is being measured.

The catheters and sensors will be removed at the end of the cystometry test.After the tests are done, your doctor will discuss the results with you,and any further treatment you may need.
