Introduction: Stent encrustation is one of the most serious complications of double J (JJ) stents. Even though encrustation is seen frequently on retained stents, ureteral stents are rarely forgotten in clinical practice. A fortyone-year-old male patient was referred to our clinic in 2002 because of a forgotten JJ stent that encrusted and associated with a stone burden incidentally seen on the ultrasonography. He declared that the JJ stent had been inserted before ESWL in 1993 because of right kidney stones and after treatment he had no complaint until 2002. We presented a case with a 10-year forgotten JJ stent associated with severe encrustation and new stone formation. The patient became stone free with combination of percutaneous nephrolithotomy and ureterorenoscopy. Minimal invasive treatment modality must be thought as the first line treatment in the severely encrusted JJ stents.
