Ureteropelvic Junction (UPJ) Obstruction

Ureteropelvic Junction (UPJ) Obstruction

Ureteropelvic Junction (UPJ) Obstruction is a condition where the normal flow of urine from the renal pelvis (part of the kidney) to the ureter is blocked or slowed down. This obstruction can lead to kidney swelling (hydronephrosis), impaired kidney function, and recurrent urinary tract infections. UPJ obstruction can be present at birth (congenital) or develop later in life due to scarring, kidney stones, tumors, or blood vessel compression. Early diagnosis and treatment are crucial to prevent long-term kidney damage.

What Causes It?

Congenital Narrowing – Developmental defect where the UPJ is abnormally narrow from birth.

Compression by Blood Vessels – Nearby arteries may press against the UPJ.

Scar Tissue – Due to previous urinary tract surgeries or infections.

Kidney Stones – Large stones blocking the UPJ.

Tumors – Rare growths pressing on the urinary pathway.

Infection-related Swelling – Severe UTIs causing tissue inflammation.

Post-traumatic Injury – Damage from accidents affecting the kidney-ureter junction.

Fibrosis – Abnormal tissue growth due to chronic irritation.

Signs & Symptoms

Persistent flank or abdominal pain.

Blood in urine (hematuria).

Recurrent urinary tract infections.

Nausea and vomiting.

Pain during urination.

Decreased urine output.

Palpable abdominal mass in severe swelling.

Fever with urinary infections.

How We Diagnose

Our specialists use advanced diagnostic methods to accurately identify and assess your condition

Ultrasound

Uses sound waves to detect kidney swelling (hydronephrosis).

Intravenous Pyelogram (IVP)

X-ray imaging with contrast dye to track urine flow.

CT Urography

Detailed cross-sectional images showing blockage location and cause.

Magnetic Resonance Urography (MRU)

MRI scan focused on urinary tract structures.

Diuretic Renal Scan (MAG3 or DTPA)

Measures kidney function and urine drainage speed.

Urinalysis & Culture

Detects infections, blood, and abnormal cells in urine.

Cystoscopy with Retrograde Pyelogram

Direct endoscopic view and contrast X-ray to locate obstruction.

Treatment Options

Personalized treatment plans tailored to your specific needs and condition

1

Observation

For mild cases without symptoms, periodic monitoring with ultrasound.

2

Antibiotics

To treat or prevent urinary tract infections.

3

Pain Management

Analgesics to relieve discomfort until definitive treatment.

4

Balloon Dilation

Non-surgical widening of narrowed UPJ using a catheter balloon.

5

Endopyelotomy

Endoscopic incision of the blockage to improve urine flow.

6

Laparoscopic Pyeloplasty

Minimally invasive surgery to remove the obstructed segment and reconnect the ureter.

7

Open Pyeloplasty

Traditional surgical repair, usually for complex cases.

Home Remedies

Hydration

Drinking adequate water to maintain urinary flow and prevent stone formation.

Avoid Excess Salt

Reduces strain on kidneys and controls swelling.

Warm Compress

Helps relieve flank pain caused by kidney swelling.

Cranberry Juice

May help lower UTI risk (should be used with medical advice).

Healthy Diet

Rich in fruits, vegetables, and low-oxalate foods to protect kidney health.

Prevention Tips

Get regular kidney function tests if you have a family history of UPJ obstruction.

Promptly treat urinary tract infections to avoid scarring.

Maintain adequate hydration daily.

Limit salt intake to reduce kidney workload.

Avoid high-oxalate foods if prone to kidney stones.

Wear protective gear during sports to prevent kidney injury.

Follow-up imaging after urinary surgeries to detect early narrowing.

Surgical Solutions

Advanced surgical procedures performed by our expert specialists

Laparoscopic Pyeloplasty

Minimally invasive gold-standard surgery to remove blockage and reconnect the ureter to the kidney.

Robot-Assisted Pyeloplasty

Robotic technology offers enhanced precision and faster recovery.

Open Pyeloplasty

Traditional approach for complex or recurrent obstructions.

Endopyelotomy

Endoscopic incision of the blockage, usually for mild cases or recurrence after pyeloplasty.

Ureterocalicostomy

Reconnecting the ureter directly to a lower kidney calyx in complex cases where UPJ repair is not possible.

Balloon Dilation with Stenting

Widening the blockage and placing a stent to maintain urine flow.
