Which term describes distention of the pelvis of the kidney?

Explanation:
Distention of a kidney structure is shown by the suffix -ectasis, which means dilation. When the kidney’s collecting system, particularly the renal pelvis, becomes enlarged, the term nephrectasis is used. This directly matches the idea of distention of the pelvis of the kidney. The other terms describe different processes: nephroptosis is downward displacement of the kidney, nephritis is inflammation of the kidney, and nephropyrosis refers to pus in the renal pelvis (pyonephrosis) rather than mere dilation.
