What are the symptoms of double J tube insertion?

Double J tube insertion is a treatment method that can play a very good therapeutic role in vesicoureteral reflux. Of course, when using this technology for treatment, if the operation is improper or the usual conditioning is improper, it may cause some uncomfortable symptoms, which may cause lower urinary tract infection in patients and easily lead to some complications, especially the upward movement of the double J tube is more common. If the activity is intense or due to gravity, the double J tube may move downward and enter the bladder, etc.

Double J tube insertion discomfort symptoms

(1) Vesicoureteral reflux: The double-J tube has a bidirectional drainage function. After using the double-J tube, the vesicoureteral anti-reflux mechanism disappears, and the bladder pressure is greater than the renal pelvis pressure, causing urine reflux. The urinary catheter should be kept open after the operation, and antibiotics should be used routinely. After the catheter is removed, the patient should be encouraged to urinate frequently to keep the bladder empty. Use with caution in patients with lower urinary tract obstruction. Infection: The presence of a double J tube increases the rate of urine reflux into the bladder and ureter, leading to retrograde infection of the kidneys. After catheterization, urine is continuously drained, and the ureteropelvic cone loses the filling stimulation, causing the ureteral peristalsis to be significantly weakened or disappear, and the urine reflux rate to increase. Therefore, overfilling of the bladder and increased abdominal pressure should be avoided. When infection occurs, antibiotics should be used rationally to control the infection and the amount of infusion should be increased to supplement nutrition.

(2) Upward movement of the double-J tube: This is the most common complication of the use of the double-J tube. The treatment is relatively complicated. The possible causes are: the lower end of the double-J tube is inserted too far into the bladder, the lower segment is not bent enough, vesicoureteral reflux peristalsis, and the double-J tube stimulates bladder contraction. The double-J tube is used to slowly retract and move upward. After the double J tube is placed, when the inner core is removed, the lower section of the double J tube is pulled upward out of the bladder.

(3) The double-J tube is moved down into the bladder: The surgeon is concerned that the length of the double-J tube placed into the bladder is not enough and that the double-J tube at the renal pelvis end is too short. Due to the patient's activities and gravity, the double J tube moved downward and fell into the bladder.

(4) The double J tube is not placed in the bladder. There is a certain amount of resistance when the double J tube passes through the intramural segment, and there is a sense of breakthrough after entering the bladder. At the same time, it continues to be inserted for 4 to 5 cm.

(5) Penetration outside the ureter or into the ureter and bladder mucosa, usually caused by violence.

(6) After catheterization, there are significant symptoms of low back pain, hematuria, and bladder irritation. The patient is not adapted to the double-J tube or the double-J tube is too hard or has a large diameter. The double J tube is placed in an improper position (the lower end is too long and crosses the midline of the bladder, or the upper end of the catheter is too high to the renal calyx) and the double J tube is placed for too long.
