(1) The use of double-J tube drainage in renal pelvis and ureter surgery simplifies the postoperative management of patients. Because the catheter is built in, the patient can move early, which reduces the chance of infection, reduces the workload of nursing significantly, and recovers quickly after surgery. , the length of hospital stay was significantly shortened.
(2) Due to the improvement in the material selection of the double J tube, the tube is soft, non-corrosive, smooth in surface, large in inner diameter, thin in wall, and has good bendability. Moving up and down, the patient feels comfortable with the catheter, and the catheter expansion effect is good, which can be indwelled for a long time, which is beneficial to the reduction of hydronephrosis and the prevention of ureteral restenosis.
(3) The double-J tube is easy to insert and remove. If the ureteral stenosis is not very serious, the tube can be expanded and drained under cystoscopy.
(4) As an adjuvant treatment of extracorporeal lithotripsy for kidney and ureteral stones, double J tube can prevent the occurrence of incarcerated stone streets and prevent large residual stones from falling into the ureter; The stent is drained to the bladder to keep the urinary tract unobstructed; when the stent is removed, the stone powder and small particles accumulated on the tube wall can be brought out together to promote the removal of the stone.
