Ureteropelvic Junction (UPJ) obstruction is a condition in which urine flow from the kidney into the ureter becomes restricted. The obstruction occurs at the junction where the kidney connects with the ureter. When urine cannot drain normally, it can collect inside the kidney, causing swelling known as hydronephrosis. If the condition persists, increased pressure can gradually affect kidney function. UPJ Obstruction Treatment in Mumbai focuses on identifying the cause and severity of the blockage and determining the most appropriate approach to restore proper urine drainage and protect kidney function.
Although UPJ obstruction is commonly associated with congenital abnormalities, it can also become apparent later in life. Adults may discover the condition during investigations for flank pain, recurrent urinary infections, kidney stones, or an incidental finding on an ultrasound or CT scan. Early evaluation is important because timely treatment can help protect kidney function.
UPJ obstruction may develop because of congenital narrowing, abnormal crossing blood vessels, scar tissue, previous surgery or trauma, or occasionally long-standing kidney stones. The severity and symptoms can vary considerably between patients.
Some individuals may have no obvious symptoms and are diagnosed during imaging. Others may experience:
In some patients, discomfort may become more noticeable after drinking a large amount of fluid. Children with congenital UPJ obstruction may have few or no noticeable symptoms, making imaging and appropriate follow-up particularly important.
Diagnosis involves assessing both the anatomy of the urinary tract and how effectively the affected kidney is functioning. The doctor may recommend different investigations depending on the patient’s symptoms and clinical findings.
Ultrasound:
An ultrasound can identify hydronephrosis and is often an initial imaging investigation.
CT Urography:
CT imaging can provide detailed information about the anatomy of the kidneys and urinary tract and may help identify the cause of obstruction.
MRI Urography:
