Abstract:
Objective To investigate the features of MSCT and multiple planar reformatting (MPR) technology in the diagnosis of urachal calculus,and also to improve knowledge and diagnosis of the disease.Methods Retrospective analysis was made on the images and clinical data of 19 cases of urachal calculus (male 12,female 7) by MSCT and MPR.Of the 19 cases,8 were confirmed by surgery and 11 were diagnosed by cystoscopy.MSCT and MPR were performed in all the cases,of which 9 cases underwent enhanced CT.Results In the 19 patients,there were 13 cases of multiple calculus and 6 cases of single calculus,with the affected sites mostly at the junction of bladder and urachus or at the urachus near the bladder.The calculi displayed circular or elliptic shape,with smooth edges and uniform density.CT values were over 400 HU and the diameter of the calculus was about 0.5-2.7 cm.Seven cases were accompanied with regional thickening of bladder wall,which was diagnosed by enhanced CT.In the 19 cases that underwent MPR,it was clearly seen that 16 cases had calculi in urachus and 3 cases had calculi on anterior wall of the bladder.Clear diagnosis could be made from the cross-sectional CT image,however,sagittal plane view or tilted sagittal plane view was more direct.Conclusions Urachal calculus often developed in urachal diverticulum on the basis of the primary disease,and CT manifestation was typical.Clear diagnosis could be made by MSCT combined with MPR.
