Chyluria is an abnormal condition in which chyle appears in the urine because of a fistulous communication between the lymphatics and the urinary tract. It is not life-threatening and spontaneous regression is reported in 50% of cases. Lymphangiography has been the main imaging modality for localization of the site of fistula, but it is invasive and requires expertise. Lymphoscintigraphy using Tc-99m labelled colloid is a safe, non-invasive, reproducible technique, which bears less radiation exposure. A 67-year-old male presented with 7-month history of chyluria following a spinal surgery. Bilateral lower limb lymphoscintigram revealed sluggish lymph flow in the left lower limb and visualization of tracer in the left kidney consistent with lymphorenal fistula. Subsequent cystography revealed appearance of chylous urine from left ureter. Patient refused surgery.
乳糜尿是一种异常情况，由于淋巴管与泌尿道之间存在瘘管交通，导致乳糜出现在尿液中。它不会危及生命，据报道50%的病例会自发消退。淋巴管造影一直是瘘管部位定位的主要成像方式，但它具有侵入性且需要专业技术。使用锝-99m标记胶体的淋巴闪烁造影是一种安全、无创、可重复的技术，辐射暴露较少。一名67岁男性在脊柱手术后出现了7个月的乳糜尿病史。双侧下肢淋巴闪烁造影显示左下肢淋巴流动迟缓，左肾有示踪剂显影，符合淋巴肾瘘。随后的膀胱造影显示左输尿管有乳糜尿出现。患者拒绝手术。
