The Value Of Transrectal Contrast-enhanced Ultrasound In Detection Of The Infiltrated Degree And Stage Of Bladder Cancer

Objective:To explore the value of transrectal contrast-enhanced ultrasound in detecting the infiltrated degree and stage of bladder cancer.Methods:In the retrospective study,51 Patients were enrolled who suffered from bladder cancer that proved by pathological examination,the images of contrast-enhanced ultrasound were analyzed to judge the invaded degree and the stage of bladder cancer,finally compared with the pathological examination.Results: The results of ultrasonogram indicated that(?T1)stage cancer in 30 cases,the lesions are limited to the mucous and submucous membrane,are superficial tumors without infiltration of the muscularis propia.;T2 stage cancer in 16 cases,the lesions invaded the muscular layer of bladder wall;T3 stage cancer in 4 cases,the lesions penetrated all the layers and invaded the surrounding tissues;T4 stage cancer in 1 case,the lesion invaded the prostate.While the pathological results testified 33 cases in(Ta?T1)stage,13 cases in T2 stage,4 cases in T3 stage,1 case in T4 stage.The coincident rate between transrectal contrast-enhanced ultrasound and pathology in judging the infiltrated degree and stage of bladder cancer is 88.24%.Conclusion:As a newly and non-invasive diagnostic method in clinical work,the transrectal contrast-enhanced ultrasound can be used to judge the infiltrated degree and stage of bladder cancer.
