A forgotten double J stent may lead to a variety of complications and their frequency increases when stents are left in place and forgotten for long periods of time. We present a case of twenty–nine years old young male who underwent bilateral ureteric reimplantation and open cystolithotomy at the age of four years for bilateral primary obstructive megaureter with a large vesical calculus and presented after twenty–five years with renal failure. His parents belonged to a low socio economic strata with a low education level. A combination of ureteroscopy, percutaneous nephrostomy, open surgery and percutaneous cystolithotripsy were used to remove the stent. The main cause of a forgotten stent is lack of communication on part of the treating doctor or lack of knowledge on part of the patient. So, its presence should be emphasised and a system should be maintained to send reminder to patient for indwelling stent.
