Pelviureteric Junction (PUJ) Obstruction Treatment in Mumbai
Many parents first hear about Pelviureteric Junction (PUJ) Obstruction during a routine pregnancy scan or an ultrasound performed after their baby is born. The report may mention "hydronephrosis" or "swelling of the kidney," leaving families anxious and confused. Does every swollen kidney need surgery? Will it affect my child's kidney function? The reassuring news is that while some children only require careful monitoring, others benefit from timely surgery that can protect the kidney and allow it to function normally.
Pelviureteric Junction (PUJ) Obstruction is one of the most common causes of urinary tract obstruction in children. It occurs in approximately 1 in 1,000 to 1,500 live births and is more common in boys than girls. The condition usually affects one kidney, most often the left kidney, although both kidneys may occasionally be involved. Thanks to routine antenatal ultrasounds, many cases are now detected before birth, allowing pediatric surgeons to monitor kidney development and intervene when necessary.
If you are looking for expert Pelviureteric Junction Obstruction Treatment in Mumbai or advanced PUJ Surgery in Mumbai, Dr. Bhavesh Doshi, Consultant Pediatric Surgeon at Dhanvantari Hospital, provides comprehensive evaluation and minimally invasive surgical treatment to preserve kidney function and help children lead healthy, active lives.
What Is Pelviureteric Junction (PUJ) Obstruction?
The kidneys continuously produce urine, which collects in a funnel-shaped area called the renal pelvis before flowing into the ureter and then the bladder.
In children with PUJ obstruction, the junction where the kidney meets the ureter becomes narrowed or blocked. As a result, urine cannot drain normally and begins to collect inside the kidney, causing hydronephrosis (kidney swelling).
Over time, persistent obstruction can increase pressure inside the kidney and gradually reduce its ability to function if left untreated.
Why Does PUJ Obstruction Happen?
In most children, PUJ obstruction develops before birth as the urinary tract is forming. It is usually congenital, meaning the child is born with it.
Possible causes include:
- Narrowing at the pelviureteric junction
- Abnormal development of the ureter
- Blood vessels crossing and compressing the junction
- Abnormal muscle development affecting urine drainage
- Rarely, scar tissue following infection or injury
Importantly, parents should know that PUJ obstruction is not caused by anything they did during pregnancy.
Could Your Child Have PUJ Obstruction?
Many newborns with PUJ obstruction have no obvious symptoms, especially when the condition is detected before birth.
As children grow older, symptoms may include:
- Recurrent abdominal or flank pain
- Swelling of the kidney seen on ultrasound
- Urinary tract infections
- Fever associated with urinary infection
- Blood in the urine
- Vomiting, especially during painful episodes
- Poor growth in severe cases
- Kidney stones in older children
Some children are diagnosed only after repeated abdominal pain or recurrent urinary infections.
Does Every Child With Hydronephrosis Need Surgery?
One of the biggest misconceptions is that every swollen kidney requires an operation.
The answer is no.
Many mild cases improve naturally as the child grows and only require regular follow-up with ultrasound scans.
However, surgery may be recommended if there is:
- Progressive increase in kidney swelling
- Declining kidney function
- Recurrent urinary tract infections
- Persistent pain
- Kidney stones caused by poor drainage
- Poor drainage demonstrated on a nuclear renal scan
The goal is not simply to correct the blockage—it is to protect the kidney before permanent damage occurs.
How Is PUJ Obstruction Diagnosed?
A detailed evaluation helps determine whether surgery is necessary.
Investigations may include:
Ultrasound
The first and most commonly performed investigation. It shows the degree of kidney swelling and monitors changes over time.
Renal Nuclear Scan (DTPA/MAG3 Scan)
This specialized scan evaluates how well each kidney functions and how effectively urine drains from the kidney.
Blood Tests
These assess kidney function and help identify any associated problems.
Urine Tests
Performed to detect urinary tract infections or blood in the urine.
Occasionally, additional imaging such as MRI or CT scans may be advised in selected cases.
What Is Pyeloplasty? The Gold Standard Treatment for PUJ Obstruction
When surgery is required, the standard treatment is called pyeloplasty.
During this procedure, the narrowed portion of the pelviureteric junction is removed, and the healthy ureter is reconnected to the kidney to create a wider passage for urine to drain freely.
Depending on the child's age and the clinical situation, surgery may be performed using:
- Open pyeloplasty
- Laparoscopic (keyhole) pyeloplasty
- Minimally invasive pediatric techniques in selected children
The operation has an excellent success rate of more than 95%, with long-term relief of obstruction and preservation of kidney function.
A temporary stent may be placed to support healing and is removed after a few weeks.
Recovery After PUJ Surgery
Children generally recover remarkably well after pyeloplasty.
Most patients:
- Stay in the hospital for one to three days
- Begin feeding soon after surgery
- Experience only mild postoperative discomfort
- Return to school and normal activities within a few weeks
- Undergo follow-up ultrasounds to monitor kidney drainage
Kidney swelling may take several months to gradually improve, even though urine drainage becomes normal much earlier.

Frequently Asked Questions
Can PUJ obstruction resolve without surgery?
Yes. Mild cases may improve naturally and are carefully monitored with regular ultrasounds and kidney function tests.
Is PUJ obstruction dangerous?
If significant obstruction is left untreated, it can gradually damage the affected kidney. Early diagnosis and timely treatment help prevent permanent loss of kidney function.
What is the success rate of pyeloplasty?
Pyeloplasty is considered the gold standard treatment and has a success rate of over 95% in relieving obstruction.
Will my child have a normal life after surgery?
Yes. Most children recover completely, maintain normal kidney function, and lead healthy, active lives after successful treatment.
How long will my child need follow-up?
Regular follow-up with ultrasound and, in some cases, repeat kidney function scans helps ensure that the kidney continues to drain well and develops normally.
A diagnosis of Pelviureteric Junction (PUJ) Obstruction can be worrying for parents, but modern pediatric urology offers highly effective treatment with excellent long-term outcomes. While many children only require careful observation, those with significant obstruction benefit from timely pyeloplasty, which restores normal urine flow and protects kidney function. Early diagnosis, regular monitoring, and expert surgical care are key to giving every child the healthiest future.
