Pyeloplasty Surgery

What is Pyeloplasty?

Pyeloplasty is a surgical procedure to correct a blockage or narrowing (stenosis) at the ureteropelvic junction (UPJ)—the point where the ureter meets the renal pelvis in the kidney. The condition is known as UPJ obstruction.

Purpose

The goal of pyeloplasty is to restore normal urine flow from the kidney to the bladder and relieve symptoms like:

Flank or back pain
Recurring urinary tract infections (UTIs)
Blood in urine
Kidney swelling (hydronephrosis)

Indications for Surgery

Congenital malformations
Scar tissue from prior infections or surgeries
Compression from crossing blood vessels
Recurrent flank pain or UTIs
Deteriorating kidney function

Types of Pyeloplasty

1. Open Pyeloplasty

Traditional method
8–12 cm incision made in the side or back
High success rate but longer recovery time

2. Laparoscopic Pyeloplasty

Minimally invasive
3–4 small incisions used to insert a camera and instruments
Less pain and quicker recovery

3. Robotic-Assisted Pyeloplasty

Uses robotic arms for precision
High success rate
Shorter hospital stay and faster healing

Surgical Procedure

Performed under general anesthesia
Blocked UPJ segment is removed
Remaining ureter is reconnected to renal pelvis
A stent (internal tube) may be placed to aid healing
Surgery takes 2–3 hours

Postoperative Care

Hospital stay: 2–3 days (laparoscopic/robotic), up to a week (open)
Pain management with medications
Follow-up imaging (ultrasound or CT scan)
Stent removal after 4–6 weeks
Full recovery in 4–6 weeks

Frequently Asked Questions

Q: What is UPJ obstruction?
A: A blockage where the ureter joins the kidney, preventing normal urine drainage.

Q: Is pyeloplasty major surgery?
A: Yes, but it’s safe and effective, especially when done laparoscopically or robotically.

Q: Can adults have UPJ obstruction?
A: Yes. Though usually congenital, it may manifest or worsen later in life.

Q: Are there risks with pyeloplasty?
A: Rare risks include infection, bleeding, urine leakage, and recurrence of obstruction.

Q: How soon can I return to work?
A: Light work: after 1–2 weeks (laparoscopic); full recovery: 4–6 weeks.

Q: What happens if UPJ obstruction is left untreated?
A: It can lead to kidney damage or failure due to prolonged pressure on the kidney.
