Surgical Treatment Of Rreteral Junction Stenosis


The article is professionally consulted by Master, Doctor Nguyen Tan Cuing. Head of Urology Department. Department of General Surgery. Vine Central Park International General Hospital Narrowing of the pyelonephritis-ureteral junction obstructs the flow of urine from the renal pelvis to the ureter. If not detected and treated promptly. The kidneys can be severely damaged. Laparoscopic surgery is the most effective treatment method of ureteropelvic junction stenosis, in which robot-assisted surgery is a new surgical direction with many outstanding advantages.

1. What is nephrotic-ureteral junction stenosis?

Renal ureteral junction stenosis is an abnormality in the junction between the renal pelvis and the ureter , which obstructs the flow of urine from the kidney to the ureter. Urine between the renal pelvis and the ureter is blocked, causing the renal pelvis to become waterlogged and enlarged. If left untreated, the kidneys can be completely destroyed.

Narrowing of the ureteropelvic junction may be unilateral or bilateral, but the incidence of stenosis on the left is twice as high as on the right. This is the most frequent cause of obstruction in children. The disease has a familial tendency, if a family member has a ureteral junction stenosis, the risk of the disease is higher.

There are many causes of narrowing of the renal pelvis-ureteral junction such as:

  • Congenital: the ureter plugs into the renal pelvis in an abnormal position, the junction has no peristalsis;
  • Abnormal blood vessels pressing on the ureter;
  • Inflammatory reaction that causes fibrosis after surgery or trauma: after ureteral surgery, infected pseudocyst, retroperitoneal fibrosis…
  • Benign or malignant tumor in the urinary tract…

The disease often progresses silently, causing no symptoms, only incidentally detected during abdominal ultrasonography or when complications have appeared with large hydro nephrosis, partial or complete loss of function.

In some cases, a person will have one or more of the following symptoms:

  • Back pain: pain on one side of the back, vague pain for a long time, recurrent back fatigue. Typical symptoms: when drinking a lot of water, it will cause back pain, claudication with nausea and vomiting or renal colic.
  • Symptoms of urinary tract infection , pyelonephritis, kidney failure .

2. Surgery for narrowing of the ureteropelvic junction

The mainstay of treatment for ureteropelvic junction stenosis is surgery.

The surgical methods of narrowing the ureteropelvic junction include:

  • Ureteroscopy widens the narrow spot

Usually used for mild or moderate uretero-pelvic junction narrowing, without blood vessels compressing the ureter. The laser is used to make a wide incision in the lumen of the narrow ureter at the pyelonephritis-ureteral junction. the ureteral tube is dilated. then a double J catheter is inserted into the ureter. There are two approaches: percutaneous nephoscopy or retrograde ureteroscopy.

  • Reconstructive surgery of the pyelonephritis – ureter

Laparoscopic or open surgery to remove the narrow segment of the pyelonephritis – ureter, then create a suture connecting the ureter with the renal pelvis.

Surgery will improve the ability of urine to drain from the renal pelvis into the ureters. Only perform nephrectomy when the kidney has lost its function (the function of the affected kidney is less than 10-15%) and the remaining kidney has good function.

Post-surgery patients need to be continuously monitored for imaging tests such as: Ultrasound of the urinary system. X-ray of the venous urograph. CT Scan of the urinary system or a kidney scan to check if the disease has recurred. .

3. Surgery with robot assist in the treatment of narrowing of the pyelonephritis – ureter

Robotic-assisted surgery is a remarkable development of surgery, a promising new approach and a development trend of the surgical industry. Robotic-assisted surgery has many advantages over classic open and laparoscopic surgery.

With sophisticated, modern structure, perfect simulation of human hand operation, wide surgical angle up to 540 that no human arm can perform, three-dimensional magnified image so the robot is capable of diagnose and perform precise, minimally invasive surgery. Therefore, surgery with robot support brings high treatment efficiency and safety, reduces pain and complications for the patient, ensures aesthetics, helps shorten hospital stay, and recovers quickly. dress.

Ureteral Stenosis is a relatively common condition, affecting approximately 1 in 1,000 people. However, it can have serious consequences, causing urinary tract infections and kidney damage. Although it is more common in men than in women, women do still suffer from the condition. Although there is a risk of complications.
