The chyluria recurred 4 months before the present hospital admission. The patient presented with acute urine retention and weight loss of 6 kg during the past 6 months. Urine biochemistry studies showed elevated concentrations of albumin (0.7 g/dL), globulin (0.6 g/dL), cholesterol (0.59 mmol/L), and triglyceride (0.89 mmol/L), confirming the diagnosis of chyluria. Intravenous urography showed a substantial filling defect in the urinary bladder. Cystoscopy revealed milky urine flowing out of the right ureteral orifice, and a large chylous coagulum presenting as a cyst-like mass in the urinary bladder. The chyluria was successfully treated with sclerosing therapy with injection of 76% Urografin (Shering AG, Berlin, Germany) into the right upper urinary tract, and the chylous coagulum was evacuated endoscopically. No evidence of chyluria recurrence has been noted during a year of follow-up, and the patient has regained 6 kg of body weight. This particular presentation of chylous coagulum in a chyluria patient has not been previously reported in the literature.[SDGs]SDG3cholesterol; meglumine diatrizoate; serum albumin; serum globulin; triacylglycerol; adult; article; bladder; case report; cholesterol blood level; chyle; chyluria; human; intravenous urography; male; recurrent disease; remission; sclerotherapy; treatment outcome; triacylglycerol blood level; urine retention; weight reduction; Chyle; Cystoscopy; Humans; Male; Middle Aged; Urinary Bladder; Urinary Bladder Diseasesjournal article105029152-s2.0-0032850359
