Pyeloplasty

From Wikipedia, the free encyclopedia

Pyeloplasty is the surgical reconstruction or revision of the renal pelvis to drain and decompress the kidney. Most commonly it is performed to treat an uretero-pelvic junction obstruction if residual renal function is adequate.

This revision of the renal pelvis treats the obstruction by excising the stenotic area of the renal pelvis or uretero-pelvic junction and creating a more capacious conduit using the tissue of the remaining ureter and renal pelvis.

There are different types of pyeloplasty depending on the surgical technique and patterns of incision used. These include the Y-V, Inverted 'U,' and Dismembered types of pyeloplasty.

A Pyeloplasty can either be done by the open or laparoscopic route.
