What is Primary Obstructive Megaureter (POMU)?
Primary Obstructive Mega Ureter (POMU) is a condition present at birth where one or both ureters are abnormally enlarged due to an obstruction. The term "primary" indicates that the condition is congenital, not caused by external factors or other medical conditions.
Causes of Primary Obstructive Mega Ureter (POMU):
Functional Obstruction, when the ureter's muscular wall may not function properly and Anatomical Obstruction when there may be a physical blockage within the ureter.
Symptoms of Primary Obstructive Mega Ureter (POMU)
- Recurrent Urinary Tract Infections (UTIs)
- Flank Pain or Abdominal Pain
- Hydronephrosis
- Hematuria
- Dysuria
Diagnosis
Diagnosis typically involves a combination of imaging and functional tests:
- Ultrasound: To detect dilation of the ureter and hydronephrosis.
- Voiding Cystourethrogram (VCUG): An X-ray test to visualize the ureter and bladder while the bladder is being emptied.
- Diuretic Renal Scintigraphy
- MRI or CT Scan:
Treatment
Treatment options depend on the severity of the obstruction and symptoms:
- Observation: In mild cases, especially in infants, the condition may resolve on its own as the child grows.
- Antibiotic Prophylaxis: To prevent UTIs in cases of recurrent infections.
- Ureteral Reimplantation: Repositioning the ureter to ensure proper urine flow.
Primary Obstructive Mega Ureter is a congenital condition characterized by an enlarged ureter due to an obstruction. While it can cause significant symptoms and complications, early diagnosis and appropriate management can lead to favorable outcomes.a, it is important to consult Dr. Aditya P.S. Sengar the best urologist in lucknow for Primary Obstructive Mega Ureter (POMU) treatment.
Megaureter and ureter obstruction treatment planning
POMU treatment in Lucknow focuses on whether an enlarged ureter is causing obstruction, infection, or kidney drainage problems. Dr. Aditya P.S. Sengar evaluates hydronephrosis, ureter size, kidney function, UTI history, and follow-up scans before deciding observation or surgery.
When POMU is suspected
POMU may be detected on antenatal scans, postnatal ultrasound, recurrent UTI, hydronephrosis, ureter dilation, or reduced kidney drainage.
Diagnosis focus
Ultrasound, renal scan, urine tests, kidney function review, and tests to rule out VUR may be needed.
Treatment planning
Mild cases may be monitored, while infection, worsening dilation, poor drainage, or reduced function may need ureteric surgery.
Tests for megaureter
These tests help the doctor understand how wide the ureter is, whether it is truly blocked and how the kidney is working.
- Ultrasound: shows the size of the ureter and kidney swelling, and is repeated over time to look for change.
- VCUG or MCU: an X-ray test that checks whether urine flows back up from the bladder, which is a different condition from blockage.
- Diuretic renal scan (MAG3 or DTPA): shows how well the kidney works and how well urine drains down the ureter.
- Urine test: looks for infection.
- MRI or CT scan: may be advised in some children for a more detailed picture of the urinary tract.
How POMU is treated
- Many babies with a wide ureter are watched with repeat ultrasound and scans, as the condition often improves as the child grows.
- A small daily dose of antibiotic may be given to some children to help prevent urine infections.
- Treatment is considered if kidney function falls, swelling gets worse, or infections keep coming back.
- In young babies, a temporary procedure to help drainage may be used first in some cases.
- The main operation is ureteric reimplantation. The narrow end of the ureter is removed, the wide ureter may be made slimmer (tapering) and it is joined to the bladder again so urine drains well.
Recovery after megaureter treatment
- First 24-48 hoursPain is managed with medicines. A catheter and sometimes a drain are in place.
- First weekMost children go home within a few days once they are eating and passing urine comfortably.
- Weeks 2-6If a stent was placed inside, it is usually removed in a short procedure. Avoid rough play until the doctor allows it.
- Follow-up over monthsRepeat ultrasound and scans check that the ureter and kidney are draining well.
The doctor will decide the timing of scans and visits for your child, so please follow that plan closely.
Cost of megaureter treatment in Lucknow
For many children with POMU, care is mostly regular scans and check-ups, which is not very costly. If surgery is needed, the cost depends on the type of operation, how long your child stays in hospital, and whether a stent needs to be removed later.

Megaureter (POMU): frequently asked questions
What is a primary obstructive megaureter?
It is an enlarged ureter caused by narrowing or poor drainage near the bladder end of the ureter.
Can POMU affect kidney function?
Yes. Significant obstruction, infection, or worsening hydronephrosis can affect kidney function, so follow-up is important.
Does every POMU need surgery?
No. Some children are monitored if kidney function and drainage are stable. Surgery is considered for selected higher-risk cases.
Which surgery is used for POMU?
Selected cases may need ureteric reimplantation or tapering/reconstruction depending on ureter size, obstruction, and bladder anatomy.
