Urine sedimentation in the bladder can occur in various circumstances and can lead to urinary obstruction/stasis with associated pain. It is usually diagnosed with an ultrasound; however, CT is also used to assess the amount and to further check for urinary stones. Depending on the composition, urine sedimentation and stones can be treated medically by alkalinisation of the urine with potassium sodium hydrogen citrate in the case of uric acid-based sedimentation/stones. Due to technical developments and improved material differentiation and characterisation in CT imaging, dual-energy CT allows for differentiation of uric acid from calcium, which can be used for sedimentation/stone composition analysis. Subsequently, treatment decisions can be made based on the findings in dual-energy CT.
膀胱内尿液沉积可在多种情况下发生，并可导致尿路梗阻/淤滞及相关疼痛。通常通过超声进行诊断；不过，CT也用于评估沉积量并进一步检查是否存在尿路结石。根据成分不同，对于尿酸盐沉积/结石情况，可使用枸橼酸钾钠碱化尿液进行药物治疗。由于CT成像技术的发展以及材料鉴别和表征的改进，双能CT能够区分尿酸和钙，可用于沉积/结石成分分析。随后，可根据双能CT的检查结果做出治疗决策。
