Hello, Uteroscopic laser lithotripsy is a surgical procedure to remove kidney stones. The Holmium laser offers a flexible ureteroscopy or endoscopic approach that is considered one of the most advanced in the treatment for kidney stones and uses a laser beam that produces thermal energy that dissolves obstructive tissue. Surgical procedures utilizing laser technology are minimally invasive but may still produce post-surgical symptoms for patients like slight pain or nausea. Nausea is due to the general anaesthesia given. Most Laser Lithotripsy procedures are safe.   Common complications include more than one round of treatments to remove the small stone pieces that were left in the kidneys. It may also cause bleeding around the kidneys that may require blood transfusion. The remaining stone pieces can also block the flow of urine and cause severe pain or blockage. A thin stent may be placed in the body after laser lithotripsy to prevent the blockage of the urine flow. Just go ahead with the surgery as this is one of the most advanced mode of treatment for kidney stones. Thanks
