Forgotten DJ Stent: A Rare Case Report of Stone Formation around Neglected Stent

Double J (DJ) ureteral stents are widely used in urological practice; however, neglected stents can result in serious complications. We present a case of a 51-year-old male with bilateral flank pain, urinary discomfort, and intermittent haematuria. He had a history of percutaneous nephrolithotomy with left-sided DJ stent placement 10 years prior, which was not removed. Investigations revealed urosepsis, acute kidney injury, and a fragmented, heavily encrusted stent with multiple renal calculi. The patient was successfully treated with cystolitholapaxy and ureteroscopic laser lithotripsy, followed by complete stent removal. This case underscores the importance of timely stent removal, patient education, and proper follow-up to prevent severe complications associated with forgotten DJ stents.
