Parapelvic Cyst In Left Kidney

Parapelvic cysts of the kidneys are simple renal cysts, which are adjacent to the renal pelvis or the renal sinus.
A Parapelvic Cyst is a little closed pouch which can be filled with fluid and is found in the kidney. They form in the sinus section of the kidney and it is yet to be established why these cysts form.
Renal cysts have been identified more frequently since CT and sonography have become common imaging methods. Parapelvic cysts are not true renal cysts but may be lymphatic in origin or develop from embryologic rests . Unlike perinephric cysts which may be the result of urine extravasation, parapelvic cysts do not communicate with the collecting system and, therefore, do not fill with contrast material during excretory urography or contrastenhanced CT. Parapelvic cysts are usually asymptomatic and require no therapy, but may lead to hypertension, hematuria, or hydronephrosis or may become secondarily infected .
