pyeloplasty
Pronunciation: PIE-eh-low-plas-tee
Surgical repair of ureteropelvic junction obstruction to restore normal urine flow from kidney to ureter.
Full Definition
Pyeloplasty is the gold standard surgical treatment for ureteropelvic junction (UPJ) obstruction in children. The procedure involves removing the obstructed segment and creating a wide, tension-free anastomosis between the renal pelvis and ureter. In pediatric patients, pyeloplasty can be performed through open, laparoscopic, or robot-assisted approaches, with the choice depending on patient age, anatomy, and surgeon expertise. Success rates exceed 95% in children, with improvement in hydronephrosis and preservation of renal function being key outcome measures.
Usage
Usage note: Specify the surgical approach (open, laparoscopic, or robotic) when relevant.
