Background: Placement of double “J” ureteral stent for various indications is common in urological surgery. The encrustation and stone formation on forgotten DJ stents can result in significant morbidity and its management remains a challenging task. Case Presentation: A 51 years male presented with history of right flank pain of over 6 months duration. He had undergone right pyelolithotomy for right renal stones 4 years ago at some other hospital. There was no medical record available and the patient did not present himself to the surgeon for follow-up. Clinical examination was unremarkable. His complete blood counts, random blood sugar, renal function tests were normal. Urinalysis revealed many pus cells/hpf. At ultrasonography, there were two renal stone with moderate hydronephrosis and a 2 cm vesical stone. An x-ray KUB, revealed a forgotten ureteric stent with stones at its both ends. The patient underwent cystoscopy and a large stone on ureteric stent was dealt with by litholapaxy. The stone on the proximal end of was managed by percutaneous lithotripsy and stent was removed. The postoperative recovery was uneventful. On stone analysis, it was made of calcium oxalate 30% and ammonium urate 70%. Conclusion: The management of encrusted stents is challenging, and each case has to be dealt with individually depending on stone site and burden, and patient related factors. Endourological management is the preferred option. Adequate patient counseling and proper stent documentation (stent placement, proposed duration and removal of stent) is necessary to minimize stent related complications.
