Comparison of transrectal ultrasound with transabdominal ultrasound in fat sufferers with bladder tumor / 中华超声影像学杂志

ABSTRACT

Objective To discuss the diagnosis value of transrectal ultrasound and transabdominal ultrasound in fat sufferers with bladder tumor.Methods In own control,transabdominal and transrectal ultrasound were used to examine 87 fat patients with suspected bladder tumor.The tumors were confirmed by cystoscope and pathological section.They were divided into 3 groups according to the size＜10 mm,10-20 mm,and＞20 mm,the detection rates of the tumors and blood flow in tumors,the diagnose accordance rates of the tumor stage of the two methods were analyzed.Results Of the 92 lesions pathologically confirmed to be bladder tumors,the diagnose accordance rate of transabdominal ultrasound was 79.3%,missed diagnosis rate was 1 7.4%,misdiagnosis rate was 3.3%,while the diagnose accordance rate of transrectal ultrasound was 95.6%,misseddiagnosis rate was 4.4%,misdiagnosis rate was 0.There was statistical significance on the detection rate of thetumor and blood flow in tumor of the two methods(P＜0.05).Also there was statistical significance on the diagnosis accordance rate of the tumor staging on Ta,T1,T2(P＜0.05).Conclusions As to detecting bladder tumors in fat sufferers,transreetal ultrasound iS obviously superior to transabdominal ultrasound.
