Pyeloplasty is a surgical procedure used to correct a condition known as ureteropelvic junction (UPJ) obstruction, where the connection between the kidney and the ureter is narrowed, causing urine to back up into the kidney. This can lead to pain, infections, and kidney damage.

During pyeloplasty, the surgeon removes the narrowed or obstructed segment of the ureter and reattaches the healthy portion to the kidney’s drainage system, ensuring a clear and open pathway for urine flow. This procedure can be performed using traditional open surgery, laparoscopic methods, or robotic-assisted techniques.

The surgery is usually performed under general anesthesia and takes about 2 to 4 hours. Patients typically stay in the hospital for a few days for monitoring and pain management. A stent may be placed temporarily to help maintain the new connection during healing.
