Stenosis laparoscopic surgery of renal tank ureter

The cause of renal-ureteral stenosis can be caused by anatomy or the function of chiping the connector that interferes with the circulation of urine from the renal tank to the ureter, leading to renal fluid retention. To improve this condition, doctors will use laparoscopic surgery to create a narrowed ureteral renal tank to help normal urine circulation avoid risks affecting the kidneys.

1. Overview of narrowing of the renal tank – ureter

Stenosis of the renal-ureteral tank is an obstruction in the pelvis of the kidneys. The pelvis of the kidneys is located at the upper end of each ureter (urine ducted from the kidneys to the bladder). The renal pelvis is shaped like a funnel for collecting urine. Under normal cases each kidney will have ureter.

The dialysis kidneys of waste and excess water produce urine. Urine is collected at the bend of the renal tank – ureter and then flows down the ureter to enter the bladder. In the case of narrowing of the renal-ureteral tank, the urine flow will slow down or stop completely. This increases the risk of kidney damage. In all cases of narrowing of the renal-ureteral tank connection only one kidney is affected.

Most obstructions that cause narrowing of the renal-ureteral tank are present at birth. This is an indication that the structure of the ureter or kidneys forms incorrectly when the fetus is developing. Some of the different obstacles that may appear at birth include:

  • Open the ureter too narrowly. There are mistakes in the number or arrangement of small muscle cells in the ureter. These cells are responsible for muscle contractions that push urine from the kidneys down to the bladder.
  • Abnormal folds in the city of the ureter can act as valves.
  • Torsion can form along the ureteral tract
  • The ureter connected to the renal pelvis at too high a position creates an abnormal angle between the ureter and the kidneys
  • There is an abnormal blood vessel that can press or distort the renal-ureteral tank connection.

Symptoms of renal-urinary stenosis are common such as urinary tract infections accompanied by fever, abdominal or back pain after drinking water, kidney stones, blood in the urine

urethra infection

Stenosis of the renal tank – ureter can cause urinary tract infections

In babies with stenosis of the renal tank – the ureter can improve on its own within the first 18 months of life. If urine flow does not improve and the blockage remains after 18 months, then surgery is the necessary method to remedy this condition.

2. Narrow laparoscopic surgery of the renal-ureter tank

To perform this surgery, the doctor will make a clinical examination to give the order to proceed. In the cases in which this surgery is in place, the congenital renal-ureteral tank stenosis has symptoms of renal fluid retention, narrowing of the renal-ureter tank connection with complications of renal fluid retention.

Patients are checked for indicators before participating in the surgery. Intravenous urological imaging, computer-layering, and tests that assess the function of the kidneys. It is important for patients to treat all urinary infections or body diseases before surgery.

Before each surgery, in addition to preparing patients, tools, operating rooms, surgeons, the preparation of records is extremely important. It includes: consultation minutes, approval minutes, pre-border receipts, mesmerizing money and minutes of commitment of patients' family members.

2.1. Laparoscopic procedure to create a bend connecting the renal-ureter tank

Patients receive in-administration anesthesia. After that, adjust the position accordingly to proceed to determine the location of the trocar. 3 trocars will be inserted into the cavity after the troitone. At this time, the surgeon will take the pelvic lumbar muscle as a landmark to dissect the ureter and ureteral surgery up to the renal tank. At the same time surgery accumulates both the front and back sides of the renal tank, the chorus, the pole under the kidneys. Next, shape the renal tank and shape the ureter, then place the innular canal with sonde and stitch the renal-innular tank back.

2.2. Post-surgery monitoring and handling of complications

After renal-ureteral tank reconstruction surgery to treat renal-ureteral tank stenosis, patients will be monitored for a torn mesitoneea. If this is the case, the body is caused by a stitching process that does not meet the standard. To remedy it, the surgeon may stitch it up or use an endoscopic organ lift tool to expand the surgery. Besides, it is also necessary to monitor if the patient has vascular damage. This condition may be caused by the course of surgery. Therefore, during surgery it is necessary to have careful surgery, clearly define the anatomy milestone, and calmly handle if necessary it is possible to switch to open surgery.

Narrow laparoscopic surgery of the renal-ureteral tank may have complications such as post-surgical urine fistula (re-retinal catheterity) or ureteral infection (antibiotic therapy)

The narrow laparoscopic procedure connecting the renal-ureteral tank can leave complications after surgery, so patients need to choose well-specialized hospitals that can be examined and treated, and can handle complications immediately, avoiding the effects later.
