Nearly 1 in 5 urology cases in India involve a blocked ureter, and most go undetected until damage begins.
From kidney stones to strictures and tumours, ureter blockages can silently harm your kidneys unless treated early.
Learn the causes, symptoms, diagnosis, and treatment options for ureter blockage in India. Is stenting needed? How much does it cost across cities, and how can we prevent recurrence?
This blog helps you make the right choices about your urinary health.
What is a Ureter Obstruction?
The narrow tubes carrying urine from your kidneys to the bladder are called ureters.
When there is something that blocks or narrows this pathway, it's known as a ureteral obstruction. This might be a stone, tumour, or an infection.
This obstruction can lead to hydronephrosis (swelling in the kidney), infections, and long-term kidney damage if left untreated.
What Causes Ureter Blockage?
Understanding the causes of blockage helps in finding the right treatment. Common causes include:
Type of Blockage |
Cause |
Details |
Ureteral Stones |
Kidney stones are passed down to the ureters and cause a blockage |
This is the most common cause in adults, causing sharp pain |
Strictures |
Strictures are scars from infections or previous surgeries |
This is often due to past UTIs or ureteroscopy surgeries |
Tumour |
Bladder, Ureter or adjacent cancers |
The tumour may compress the ureter or grow inside it, causing the blockage |
Congenital Anomalies |
These are structural abnormalities present from birth |
Ex: Ureteropelvic junction obstruction |
External Compression |
Pregnancy, pelvic tumours, fibroids |
They compress the ureters from the outside, affecting the urine flow |
Infection/Inflammation |
Urinary tract infection and inflammation |
It is rare, but chronic inflammation can cause narrowing of the ureter |
According to the Urological Society of India, ureteral obstructions make up 12-18% of urology cases annually.
What are the Symptoms of Ureter Obstruction?
The symptoms are not detected in the early stages, but as the obstruction worsens, the following signs may appear:
-
Severe back or side pain (especially when related to stones)
-
Nausea
-
Vomiting
-
Reduced urine output
-
Blocked Urination
-
Urinary tract infections
-
Fever and chills (when the infection sets in)
-
Kidney swelling
If left undiagnosed and untreated, it can lead to permanent kidney damage, high blood pressure, or sepsis.
What Tests Are Used to Diagnose Ureter Blockage?
The following tests are prescribed to confirm ureteral narrowing.
Test |
Purpose |
Cost |
Ultrasound |
Detects kidney swelling and stones |
₹800 - ₹2000 |
CT Scan |
Detects blockage, cause, and the extent |
₹3000 - ₹20,000 |
IVP (X-ray with dye) |
Used to visualise urinary tract flow |
₹3000 - ₹7500 |
Renal Scan (DTPA) |
Used to measure kidney function |
₹2500 - ₹7500 |
Urine tests and Urine culture |
Detects blood in urine and infections |
₹500 - ₹2000 |
How is Ureter Obstruction Treated?
Treatment options depend on the cause, location, severity, and whether one or both ureters have obstruction.
Ureteral Stenting
-
A thin, flexible tube is placed in the ureter to bypass the blockage
-
This is a short procedure taking less than an hour
-
This helps in urination flow while treating the underlying cause of obstruction
-
Costs ₹50,000 - ₹65,000 in major cities of India
Ureteroscopy
-
Used to remove stones or detect tumours through biopsy
-
There are no cuts as the ureteroscopy is inserted through the urethra
-
A Laser is used to fragment the stones
-
Costs ₹90,000 - ₹150,000 in major cities of India based on the laser type, stone type, stone size and hospital facilities.
Percutaneous Nephrostomy (PCN)
-
This is an option when the stent placement fails or is not feasible
-
A tube is inserted directly into the kidney to drain urine externally
-
Costs ₹55,000 - ₹70,000 in major cities of India
Surgical Repair
-
Pyeloplasty for UPJ obstruction
-
Reimplantation of the ureter in complex strictures
-
Costs ₹140,000 - ₹2.5 lakhs in major cities of India
Cancer Treatment
-
Ureter tumours may need resection, chemotherapy, or nephroureterectomy
-
Bladder cancer affecting the ureters will be managed by uro-oncologists

-
Persistent infections

-
Untreated strictures
Preventive Tips:
-
Stay hydrated

Treat UTIs early
-
Get regular imaging follow-ups
