02. Why do you need to put the tube after surgery?
Facilitates drainage of hydronephrosis, especially in cases of infection secondary to long-term obstruction.
It is conducive to the repair of the ureteral wall after surgery and prevents inflammatory narrowing of the ureter.
It can stimulate the dilation of the wall of the ureter, which is conducive to the excretion of stones from the body.
For patients with large stone residues that require secondary surgical treatment, good surgical conditions are provided to prevent postoperative stones from blocking the ureters again, secondary to renal colic and hydronephrosis.

04. Do the placed double J tubes need to be removed? How to pull?
The double J tube is to be pulled out, and the specific removal time will vary according to the situation of each patient, and the extubation will be returned to the hospital according to the doctor's instructions at the time of discharge (ranging from 1-3 months).
Simply remove the double J tube, do not need to be hospitalized, follow the doctor's instructions and return to the surgical hospital on time for removal.
05. What are the precautions for placing double J tubes?
Do not hold urine: normal people ureter in the bladder opening has an anti-reflux effect, urine in the bladder can not return to the kidney along the ureter, after placing the double J tube, the renal pelvis and bladder pathway open, if the urine will make the urine return to the kidney along the double J tube, easy to cause waist swelling and urinary tract infection, long-term urine reflux oppression of the renal pelvis and even affect kidney function.
Drink more water: Keep the daily urine volume of more than 2000ml, not only can prevent infection, help some small stones to pass, but also to avoid the formation of double J tube wall stones.
Avoid strenuous lumbar activity: Strenuous lumbar activity may cause the double J tube to rub against the tissue, causing bleeding in the urine, and do not suddenly squat and stand up, because gravity will cause the double J tube to shift and fall out. When changing position, move slowly.
Common discomfort symptoms after catheterization: low back pain, hematuria, urinary pain, etc., most of which are normal phenomena, generally do not need to be treated, if there is obvious hematuria (still can not improve after drinking a large amount of water) or fever, low back pain is unbearable, etc., it is recommended to come to the hospital for examination and treatment in time.
