Part of speech: noun

Definitions

1. A surgical procedure aimed at correcting the obstruction of urine flow from the kidney to the bladder by reconstructing the renal pelvis
2. This operation involves reshaping the renal pelvis to eliminate blockage and restore normal urinary drainage from the kidney
3. A medical intervention performed to repair or reconstruct the area where the renal pelvis connects with the ureter, ensuring proper urine passage

Etymology: Pyeloplasty is a modern medical coinage built from two Greek elements. "Pyelo-" comes from the Greek "pyelos", meaning a trough or basin, and in anatomy it names the renal pelvis, the funnel-shaped cavity where the kidney gathers urine before it drains toward the bladder. The second element, "-plasty", comes from the Greek "plassein", to form or mould, and is the standard suffix for surgery that reshapes or rebuilds a body part, as in rhinoplasty for the nose. Put together, the word describes exactly what the operation does: it remodels a basin that has become narrowed or blocked, usually where it joins the ureter, so urine can flow freely again. Nothing about the term is ancient. Surgeons assembled it from classical roots when the procedure needed a name, so the Greek parts describe the anatomy and the action rather than preserving any older medical tradition.
