Lidocaine Jell Instillation During Ureteroscopic Stone Fragmentation Effectively Reduces Stone Migration

Abstract Introduction: Inadvertent migration of stone during ureteroscopy is a relatively common problem. In this video we are describing a cost-effective technique for prevention of inadvertent stone pushback during ureteroscopy. The current study and our previous work1 studied the efficacy of Lidocaine jelly instillation proximal to the ureteral stone during intracorporeal lithotripsy using a semi rigid ureteroscope for the prevention of retrograde migration and improvement in stone-free rate. The video is on MPEG format and the run time is 10 min. Materials and Methods: The technique described involved Lidocaine jelly instillation proximal to the stone before fragmentation. The jell is instilled either by using an open end ureteral catheter bypassing the stone under Ureteroscopic guidance or by bypassing the stone with the ureteroscope and instilling jell via the working channel of the ureteroscope. The ureteroscopy was performed using an 8F, 7F, or 6.4F semi rigid ureteroscope. A 5F ureteral stent was...
