Abstract
We report a case of 61-year-old male who presented with chyluria after partial nephrectomy. During workup for appendicitis, an incidental exophytic renal mass was revealed on CT scan. The patient ultimately underwent uncomplicated open partial nephrectomy. Postoperatively, his JP drain output turned milky white with urine remaining clear. JP fluid analysis was consistent with lymph. At 3 weeks postsurgery, his drain output decreased, but his urine turned milky white. Urinalysis confirmed fat in the urine. CT imaging revealed chyloma/urinoma with extravasation. The patient was initially treated conservatively, with a medium-chain fatty acid diet and then ureteral stenting. His stent was eventually removed and his chlyuria resolved 14 weeks later.In nonendemic countries, nonparasitic chyluria is exceedingly rare and postsurgical chyluria even more so. We review the sequelae of untreated disease and surgical options for intractable chyluria not responsive to conservative management.In non-endemic countries, non-parasitic chyluria is exceedingly rare, and post surgical chyluria even more so. We review the sequelae of untreated disease and surgical options for intractable chyluria not responsive to conservative management.
