The differential diagnostic value of color Doppler ultrasonography in cystitis glandularis / 中华超声影像学杂志

ABSTRACT

Objective To probe the differential diagnostic value of color Doppler ultrasonography(CDU)in cystitis glandularis.Methods Thirty-nine cystitis glandularis and 192 bladder cancer were examined with CDU.The location,shape,boundary,internal echo and relationship with wall of urinary bladder of lesion were observed.Internal blood flow disposition of lesion were detection.The results of CDU were compared with those of cistoscope biopsy and pathologic diagnosis after operation.Results 59.0%(23/39)cystitis glandularis and 52.9%(74/140)bladder cancer lesions located in trigone of bladder and surrounded the orifice of ureter.53.8%(21/39)cystitis glandularis showed part wall thickening and 72.9%(140/192)bladder cancer showed single nodus or bolus.Sacculiform anechoic area were observed in 69.2%(27/39)cystitis glandularis and were not observed in bladder cancer.Punctiform hyperechogenicity appeared in periphery of 48.4%(93/192)bladder cancer and 7.7%(3/39)cystitis glandularis.The detection rate of interior blood flow signal of bladder cancer was 84.9%(163/1 92),which was obviously higher than that of cystitis glandularis.The diagnostic accurate rates of CDU in cystitis glandularis and bladder cancer were 84.6%(33/39)and 95.3%(183/192),respectively.Conclusions CDU can clear display the location,shape,boundary,internal echo and relationship with wall of urinary bladder of cystitis glandularis and is of important value in diagnosis,differential diagnosis and clinical fllow-up of cystitis glandularis.
