In imaging, dilation of the renal pelvis is referred to as

Explanation:
Pelviectasis describes dilation of the renal pelvis. On imaging, if the dilation is confined to the renal pelvis with the calyces remaining normal, this finding is pelviectasis. If the calyces are also dilated, the condition is hydronephrosis, indicating dilation of the entire collecting system. In this question, the dilation specifically refers to the pelvis, making pelviectasis the correct descriptor. The other options don’t describe pelvis dilation: parapelvic cysts are cysts adjacent to the pelvis that can mimic dilation, renal sinus lipomatosis is fat in the renal sinus, and renin is an enzyme unrelated to structural dilation.
