How do you get rid of scar tissue in the ureter?
Scar tissue creates a narrowing (stricture) in the ureter. Urine then can’t flow down the ureter properly and backs up into the kidney….During the surgery:
- The narrowed portion of the ureter is cut out.
- A long, flexible tube called a stent is put into the ureter.
What causes ureter scarring?
A ureteral stricture frequently results from a buildup of scar tissue or inflammation around the ureter, often due to an external traumatic injury or as a complication of a previous surgery, such as a procedure to manage kidney stones or surgeries that affect the area surrounding the ureters, including gynecologic or …
Can a ureteral stricture heal itself?
In some patients, the stricture may return but may not need additional treatment. But if it causes obstruction, it can be treated with urethrotomy or dilation. Repeat open surgery may be needed for serious strictures that come back.
What happens if your ureter is cut?
An unrecognized or mismanaged ureteral injury can lead to significant complications, including urinoma, abscess, ureteral stricture, and potential loss of ipsilateral kidney or even death.
Can your ureter be replaced?
Ileal ureter replacement is a technically feasible surgery to be performed in any patient requiring ureteral reconstruction despite a normal contralateral kidney. As such, it is a better alternative than nephrectomy in cases of complex and multiple ureteral strictures.
How do you fix a ureteral stricture?
Treatment may include:
- Laparoscopic or robotic surgery.
- Endoscopy to cut through the blockage, sometimes using a balloon to dilate the ureter.
- Percutaneous nephrostomy, a needle inserted through the back into the kidney to drain urine.
- Ureteral stent to drain urine from the kidney to the bladder, bypassing the stricture.
What causes scar tissue in the ureters after surgery?
The ureters are the tubes that carry urine from the kidneys to the bladder. Scar tissue may form in a ureter after an accident or surgery. Or it may form because of a health problem such as endometriosis or cancer.
What kind of surgery is needed for ureteral stricture?
The type of surgery performed for injury to the ureter depends upon where the location and the length of the scarring has occurred. When the stricture or scar in the ureter is low and near the bladder usually the ureter can be reconnected to the bladder, removing the area of scar (this operation is called neo-cystotomy).
What to do if you have an ureteral blockage?
Surgery: If the blockage is due to a birth defect or tumor, doctors can often perform surgery to remove the obstruction. Stent: Doctors can insert a stent (a thin, flexible tube) into the ureter to keep it open and allow urine to flow.
What kind of tissue is used to repair the ureter?
If a large section is removed, tissue is used to repair the ureter. This tissue is taken from another part of the body, such as the bladder. The cut ends of the ureter are then stitched together.
The ureters are the tubes that carry urine from the kidneys to the bladder. Scar tissue may form in a ureter after an accident or surgery. Or it may form because of a health problem such as endometriosis or cancer.
Which is the best treatment for urethra scarring?
For patients who are carefully selected with optimal stricture characteristics, primary bulbar strictures of <1 cm which are soft, then a stricture-free rate of up to 50%–70% can be achieved. Thus, urethrotomy remains the first-line therapy for these selected patients [21], [22].

What happens if a stone is stuck in the ureter?
Here, a telescope is placed up into the ureter and the stones are fragmented with a laser. The ureter can be injured particularly if the stone is large or stuck to the wall. The injured ureter can become badly scarred and prevent urine draining from the kidney. Such scar tissue of the ureter requires surgical reconstruction.
