A ureteral stricture is when the ureter, which is the tube that links the kidney to the bladder, gets narrower. This happens when scar tissue grows. This narrowing can stop or slow down the flow of urine, which can make the kidneys swell (hydronephrosis) and not work appropriately.
There are many things that might cause strictures, such as surgery in the past, damage to the ureter, radiation therapy, infections like TB, or kidney stones. People are also often born with congenital strictures. When tumours or fibrosis in surrounding tissues push to the outside, it might cause obstruction.
At first, the symptoms may not be visible, but they frequently include flank discomfort, urinary tract infections, blood in the urine (haematuria), and fever if an infection arises.
To make a diagnosis, doctors employ imaging tests like ultrasounds, CT scans, or tests that check urine flow. The goal of preventive care is to keep underlying conditions under control and stop injuries from happening so that stricture formation is less likely. Getting a diagnosis and treatment as soon as feasible is vital for keeping the kidneys healthy and making the symptoms of ureteral strictures less severe.
The only method to help people with this potentially deadly disease is to get them the best care from urologists.
