Purpose: We describe a simple method to assist stone localization during shock wave lithotripsy in the presence of a Double J* stent. Materials and Methods: A 4F whistle tip ureteral catheter is passed alongside a previously inserted 6F Double J stent. The tip of the ureteral stent is positioned in the lower or mid third of the ureter. Contrast material is injected through the ureteral catheter during lithotripsy to assist stone localization. Results: This technique has been successful in localization of poorly opacified renal stones during lithotripsy. Conclusions: Radiolucent and poorly calcified renal stones can be easily localized during shock wave lithotripsy, despite the presence of a Double J stent. No special catheters or stents are required for this technique.
