Abstract:
Objective To evaluate the value of cystography with low-concentration contrast medium in diagnosing small tumor of urinary bladder.Methods Cystography in 187 cases with bladder disease from 1992 to 2001 was performed using 6%～8% Meglumine Diatrizoate 100～120 ml under TV monitored.Radiogrames of A-P position and bilateral oblique position were taken when the focus was found.The radiogram on patient’s position at head low was adopted when necessary.Results Of 187 cases,106 cases of bladder tumors were detected,including 8 cases of small bladder tumor(≤1.0 cm in diameter),3 cases were misdiagnosed,the detectable rate was 73.0%.All cases were confirmed by operation and pathologiy.In these 8 cases,1 case was adenocarcinoma,5 cases were transitional epithelia cell carcinoma,2 cases were papilloma.The X-ray appearances were nipple-like or cauliflower shape with filling defect,a narrow pedicel could be occasionally found in papilloma or transitional epithelia cell carcinoma and it had somewhat movement when changed patient’s position.Conclusion Cystography with low-concentration contrast medium is a non-injury procedure in diagnosis of small tumor of urinary bladder.
