After kidney stone surgery, various drainage lines will be left in place. Commonly used drainage lines and recovery time: 1. Urinary catheters will be left in place and will be removed 1-3 days after surgery. Shortly after removal of the catheter, irritating symptoms such as frequent urination, urinary urgency and painful urination may occur. Usually, the normal urination can be resumed 24 hours after the removal of the tube.2. In case of percutaneous nephrological surgery, a nephrostomy tube will be left in the lumbar region, and the nephrostomy tube is usually removed about 5 days after the surgery. If bleeding is encountered, the time may be extended appropriately. Full recovery is usually achieved about 1 week after extraction. After the removal of the tube, stenting of the ureter is usually done 1-3 months after the surgery, depending on the recovery. Usually, during the period of ureteral stent tube, some patients may have discomfort such as back pain or abdominal swelling and pain, but most of them are mild. They can return to normal conditions 24 hours after removal of the tube.
