Identifying the variables associated with XXXX during transrectal ultrasonography of the prostate.

@entity1 @entity1069 @entity6713 @entity158 @entity1486
OBJECTIVE: The purpose of this study was to prospectively investigate the degree of @entity158 experienced by the @entity1 receiving transrectal ultrasonography (TRUS) of the prostate by applying a visual analog scale. We also identified the clinical parameters influencing @entity158 during the TRUS examination. MATERIALS AND METHODS: Records were obtained from a prospective database for male @entity1 who received TRUS of prostate in the outpatient department of Chang Gung Memorial Hospital, Taiwan, from January 2014 to June 2014. The @entity1 underwent a detailed physical examination and medical history review. Immediately after the TRUS examination, the @entity1 completed questionnaires based on a ten-point visual analog @entity158 scale. The variables of interest were age, body mass index, prostate volume, prostate sagittal length, @entity1486 , previous TRUS experience, external @entity6713 , anal surgical history, @entity1069 , and image artifact caused by stool in the rectum. All variables were correlated to the visual analog scale by applying multivariate regression analysis. RESULTS: By using linear regression analysis, we identified the independent factors that affected the @entity158 score during the TRUS examination. The @entity1 who received the examination for the first time or had longer prostate sagittal lengths, external @entity6713 , anal surgical history, or stool stored in the rectum experienced more @entity158 during the TRUS examination. Furthermore, the @entity158 was reduced when we provided the @entity1 with a detailed explanation before the procedure and allowed them to observe the real-time images during the examination. CONCLUSION: Although a TRUS examination is uncomfortable for @entity1 , after having identified the factors affecting @entity158 , physicians can assist @entity1 in reducing @entity158 during the procedure, thus providing higher quality examinations.
