Cystic echinococcosis or hydatid disease is a zoonotic parasitic infection caused by larval stage of cestode Echinococcus spp. Humans are an accidental intermediate host and present with the involvement of different organs, the liver being the most common while kidney is the rarest site. Here, authors are reporting a case of a 55-year-old woman who presented with renal failure and was found to have a right-sided intrarenal hydatid cyst, diagnosed and treated with nephroscopy without sacrificing the kidney. She had an uneventful postoperative course and her renal function improved dramatically. She is now on oral albendazole therapy and doing well on follow-up. To the best of our knowledge, renal failure has never been reported in the literature as clinical manifestation of intrarenal hydatid cyst in adult population.
