There are two main surgical procedures for kidney stone surgery, including Holmium laser lithotripsy and percutaneous nephrolithotripsy. The process of removing the tube after surgery is basically to go to the hospital where the original surgery was performed and remove it under the correct operation of the doctor. 1. Holmium laser lithotripsy with flexible ureter: The indwelling ureteral stent tube is usually taken out 2~4 weeks after the operation, and it is necessary to make sure that the stones have been expelled and the position of the ureteral stent tube is confirmed by a review before removing the tube. First of all, the patient lies flat on the operating bed, legs elevated, take the lithotomy position, disinfection, local anesthesia, and then the application of cystoscope through the urethra into the bladder, looking for the ureteral stent tube, pincers clamp the tube, with the removal of the cystoscope will be double J-tube extraction outside the body, the whole process of operation is simple, very small trauma. 2. Percutaneous nephrolithotripsy lithotripsy: Generally, three tubes will be left in the body after the operation, one ureteral stent tube, one nephrostomy tube and one urinary catheter. Patients need absolute bed rest after surgery to prevent postoperative renal hemorrhage. The nephrostomy tube and the urinary catheter can be removed in about 3-7 days respectively. When taking the urinary catheter, the catheter can be removed only by suctioning out the saline in the balloon. When taking the nephrostomy tube, it is necessary to remove the local suture first, and dangerously suction out the saline in the air bag, so that the nephrostomy tube can be pulled out. After pulling out the tube, there may be short-term urine leakage, and it is necessary to change the medication in time to keep it clean. The ureteral stent tube is usually taken out 2~4 weeks after the operation, and the process is the same as that of taking out the tube after Holmium laser lithotripsy with ureteral flexible lens. In addition, it is recommended to take out the tube in time after kidney stone surgery, and do not forget to take out the tube.
