Evaluate the difference in the subjective in pain of using different probes for transrectal ultrasound of prostate
Material and Method:
From July 2014 to December 2014, patients undergoing transrectal ultrasound of prostate (TRUS) were randomly divided into two groups, using two different probes. A visual analogue (VAS) was used to evaluate the subjective perception of pain in these patients.
A significant difference was found in VAS between the two groups. The patient felt less pain during TRUS examination when using micro convex transducer. Besides, patients with external hemorrhoid, longer prostate sagittal length, and artifacts caused by stool were all found to be associated with more pain. The usage of micro convex transducer can help to reduce the pain for the patients with external hemorrhoids, whereas there was no difference of pain perception when the patient has previous rectal surgery or artifacts caused by stool.
We identified the factors of pain associated with TRUS. Micro convex transducer caused less pain associated TRUS than Bi-planed linear transducer.
