Ureteral stents (Double-J stents) have been widely used in urology to prevent or relieve ureteral obstruction and have become an integral part of urologic practice. However, if ureteral stents are kept for a prolonged period or neglected, they can cause significant morbidity because of complications such as stent migration, encrustation, occlusion, stone formation, and fragmentation. Therefore, it is crucial to remove stents as soon as possible after they have served their purpose, to prevent complications and morbidity. Read More

Large staghorn calculi in unascended pelvic kidneys and in normally located kidneys with anatomy unsuitable for percutaneous nephrolithotomy have to be treated via pyelolithotomy. When performed laparoscopically, the extraction of these staghorn calculi, without extending skin incision at the port site is challenging. We describe the successful use of laparoscopic laser lithotripsy, intracorporeally, with the entrapped calculus inside the endocatch bag, for fragmentation and retrieval without extension of skin incision.
