What is Laparoscopic Pyeloplasty?
Laparoscopic pyeloplasty is a minimally invasive surgical procedure used to treat ureteropelvic junction (UPJ) obstruction — a blockage where the ureter meets the kidney. This blockage can impair urine flow, leading to kidney swelling (hydronephrosis), infections, and progressive kidney damage if untreated.
The laparoscopic approach involves making small incisions, inserting a camera (laparoscope), and using specialized instruments to remove the obstructed segment of the ureter and reattach the healthy portion to the renal pelvis, restoring normal urine flow.
Understanding the Laparoscopic Pyeloplasty Procedure
UPJ obstruction can be congenital (present from birth) or acquired due to kidney stones, scar tissue, tumors, or blood vessel compression. Symptoms may include flank pain, recurrent urinary tract infections, blood in urine, and decreased kidney function.
The laparoscopic pyeloplasty procedure involves:
- Small abdominal or flank incisions for instrument access.
- Removal of the narrowed or blocked ureteral segment.
- Reconstruction of the ureter-kidney connection to allow normal urine drainage.
- Placement of a temporary stent inside the ureter to support healing.
Step-by-Step Laparoscopic Pyeloplasty
1
Preoperative Evaluation
Imaging tests (ultrasound, CT urogram), kidney function tests.
2
Anesthesia
General anesthesia is administered.
3
Small Incisions
Typically 3–4 keyhole cuts in the abdomen or flank.
4
Insertion of Laparoscope
High-definition visualization of the surgical site.
5
Excision of Obstructed Segment
Removal of narrowed ureter portion.
6
Reconstruction
Healthy ureter is reattached to the renal pelvis.
7
Stent Placement
Temporary stent ensures proper healing.
8
Closure & Recovery
Incisions closed with sutures or glue.
Benefits of Laparoscopic Pyeloplasty
Minimally Invasive
Smaller incisions, less scarring.
Faster Recovery
Return to daily activities sooner.
High Success Rate
Comparable to open surgery but with less discomfort.
Lower Complication Risk
Reduced blood loss and infection risk.
