pyeloplasty
Pronunciation: PIE-eh-loh-plas-tee
Surgical reconstruction of the renal pelvis to correct ureteropelvic junction obstruction.
Full Definition
Pyeloplasty is the gold standard surgical procedure for correcting ureteropelvic junction (UPJ) obstruction, which impedes urine flow from the renal pelvis into the ureter. The procedure involves removing the obstructed segment and creating a new, tension-free anastomosis between the renal pelvis and ureter. Pyeloplasty can be performed through open, laparoscopic, or robot-assisted approaches, with success rates exceeding 95% in relieving obstruction and preserving renal function.
Usage
Usage note: Distinguish from pyelotomy (incision only) and other reconstructive procedures.
