Chyluria occurs in all its forms with milky urine, recurrent episodes of acute urinary retention, left renal colic and proteinuria. In non-parasitic or iatrogenic diseases, it is secondary to communicate between the cisterna system of the chyli and the lymphatics of the calyx system of the left urinary tract with a retrograde passage of a kilo and its appearance in the urine which therefore take on a milky appearance [1, 2]. Sometimes, episodically, especially after the ingestion of a high-fat meal, the quantity of kilo is so abundant that it can cause obstruction of the upper urinary tract and of the bladder, resulting in renal colic or acute urinary retention that may require their unblocking with double J stent or bladder catheter [3, 4]. After conservative attempts with a fat-free diet or with the parenteral diet, in case of their failure, surgery must be performed by performing a para-aortic and renal hilum lymphadenectomy and, in severe cases, with intraperitonealization of the kidney and left ureter. This is the case of the patient reported below and successfully treated recently with an innovative “open” surgical technique.
