Pyeloplasty is a surgical procedure used to correct ureteropelvic junction (UPJ) obstruction, a condition where the connection between the kidney and ureter becomes narrow or blocked. This blockage hinders urine flow from the kidney to the bladder and can lead to pain, infections, or kidney damage.
Under the expert care of Dr. Ajinkya Kasekar, pyeloplasty is performed through laparoscopic, robotic, or open techniques, ensuring long-lasting relief and preservation of kidney function.

What Is UPJ Obstruction?

UPJ obstruction occurs when the junction between:

Kidney (renal pelvis) → Ureter (urine tube)
is narrowed or blocked.

This leads to urine buildup in the kidney (hydronephrosis), causing pain and swelling.

It may be caused by:

• Congenital defect (present from birth)

• Scar tissue

• Crossing blood vessels

• Stones

• Previous surgeries

• Trauma or infections

Pyeloplasty is considered the gold-standard treatment for this condition.

When Is Pyeloplasty Needed?

You may need pyeloplasty if you have:

• Persistent flank pain

• Recurrent kidney infections

• Hydronephrosis on ultrasound

• Poor urine drainage

• Kidney function decline

• Stones caused by obstruction

• Recurrent vomiting (common in children)

Types of Pyeloplasty

1. Laparoscopic Pyeloplasty

• Small keyhole incisions

• Minimal pain

• Faster recovery

• Highly effective

2. Robotic Pyeloplasty

• Robot-assisted precision

• Ideal for complex or recurrent UPJ obstructions

• Excellent cosmetic and functional results

3. Open Pyeloplasty

• Used for complicated anatomical cases

• Traditional but extremely effective

How Pyeloplasty Is Performed

1. A narrow or blocked portion of the UPJ is identified.

2. The narrowed segment is removed.

3. The healthy ureter is reconnected to the renal pelvis to restore urine flow.

4. A temporary DJ stent is placed to support healing.

5. Incisions are closed depending on the surgical approach.

Surgery typically takes 1.5–3 hours.

Benefits of Pyeloplasty

• Permanent solution for UPJ obstruction

• Restores normal urine flow

• Relieves pain and swelling

• Prevents kidney damage

• High long-term success rate (success >95%)

• Faster recovery with laparoscopic/robotic methods

Recovery After Pyeloplasty

Most patients:

• Stay in the hospital for 1–2 days (laparoscopic/robotic)

• Experience mild discomfort for a few days

• Resume normal activities in 7–14 days

• Need DJ stent removal after 4–6 weeks

• Undergo ultrasound or scans to confirm improvement

Children typically recover very quickly.

Signs of UPJ Obstruction in Adults & Children

Adults:

• Flank pain

• Recurrent kidney stones

• Urinary infections

• Nausea/vomiting

• Reduced kidney function

Children:

• Abdominal swelling

• Vomiting

• Irritability

• Poor feeding

• UTI symptoms

Pyeloplasty provides excellent long-term results in both.
