Double J (DJ) ureteral stents are frequently used as a natural consequence of common use of endoscopic procedures. Even though use of these stents is practical and safe, undesired problems such as urinary tract infection, kidney dysfunction may develop in case of their long stay in the body. DJ stents staying for a long time in the body due to forgotten by urologist and frequently by the patients or due to carelessness of the patients which may cause serious medical and legal problems.
Herein, we reported two cases with DJ stent placed 4 and 2 years ago after open kidney stone operation and encrusted as they were forgotten. These 2 cases were treated by application of ESWL, endoscopic laser cystolithotripsy, suprapubic percutaneous cystolithotripsy, ureteroscopic lithotripsy and percutaneous nephrolithotomy methods consecutively. In conclusion, cases with DJ stents should be informed and warned strictly to avoid rare but serious problems due to delay or forget of these stents. We think that with an algorithm including the consecutive treatment alternatives management of encrusted DJ stents might be more successful.
