Pyeloplasty
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. The dismembered type of pyeloplasty (called as Anderson-Hynes pyeloplasty) is the most common type of pyeloplasty. It is interesting to note that this was described in relation to retrocaval ureter (now renamed as preureteric vena cava). Another technique of pyeloplasty is Culp's pyeloplasty, in this method a flap is rotated from dilated pelvis to decrease narrowing of ureter.
A pyeloplasty can either be done by the robotic, open, or laparoscopic route.
Kidney
The kidneys, organs with several functions, serve essential regulatory roles in most animals, including vertebrates and some invertebrates. They are essential in the urinary system and also serve homeostatic functions such as the regulation of electrolytes, maintenance of acid–base balance, and...
