长期卧床膀胱结石患者的CT表现

目的：探讨长期卧床患者膀胱结石的特征性CT表现。方法：回顾性分析23例长期卧床膀胱结石患者及11例对照组非卧床膀胱结石患者的CT表现,对其膀胱结石的CT表现进行对比分析。结果：长期卧床患者膀胱单发结石15例,结石多贴近膀胱后壁且偏于一侧,其中新月形9例,不规则飘带形与短线条形各3例;多发结石8例,结石主要沿膀胱后壁分散或聚集分布,其中弧形堆叠状2例,多发卵圆形与沙粒状各3例。对照组非卧床膀胱结石患者11例,结石均为单发卵圆形,其中6例可见同心环征象。结论：长期卧床患者膀胱结石的CT表现具有以弧形为主的多样性特征。

CT features of bladder calculi in patients with long-term bedridden history

Objective：To investigate the CT features of bladder calculi in patients with long-term bedridden history.Methods：CT findings of 23 patients with bladder calculi and long-term bedridden history and 11 patients also with bladder calculi yet without history of long-term bedridden as the control group were retrospectively analyzed.Results：15 patients with history of long-term bedridden had solitary bladder calculi,the calculi mostly cling to the posterior wall of bladder and lie on one side,with crescent shape（9 cases）,irregular floating belt shape and short straight linear shape（3 cases for each）.Multiple calculi in 8 cases were scattered or gathered,mainly lined along posterior wall of bladder,manifested as curvilinear calculi and piled up in layers（2 cases）,multiple oval and sand-like calculi（3 cases for each respectively）.Of the control group,the bladder calculi were oval in shape,with concentric ring sign in 6 patients.Conclusion：Relative characteristic CT findings of bladder calculi could be seen in patients with long-term bedridden history.
