Complications after renal allograft transplantation are not so uncommon. Most complications are related to graft rejection, immune-suppressive drug toxicity and the operative procedure. Stents are placed after a transplant to prevent urine leak at the site of ureteric reimplantation, to facilitate an early healing in immune-suppressed individuals and to prevent obstruction at the site of ureteral anastomosis. We report a case of a renal allograft recipient with a forgotten ureteral double J stent. where the stent remained in situ for more than 4 years and further complicated by encrustation and stone formation at both the bladder and renal pelvic ends. The stone over the bladder coil was removed by holmium laser cystolithotripsy while the encrusted renal pelvic coil was removed by percutaneous approach. This case is presented for its rarity and also to emphasise on the need for maintenance of a stent register in order to ensure avoidance of such preventable complications.
