The parapelvic renal cyst is a relatively common finding on routine urological examination, but only rarely needs treatment. We here examined all parapelvic renal cyst patients who consulted our Department between April 1998 and December 2004 with the focus on potential for malignant development.
The parapelvic cyst is a simple cyst that forms in the kidney .Simple kidney cysts occur more and more as we age.There is no known exact reason for why ,a parapelvic cyst forms, but they are always in the sinus region of the kidney. Sometimes a parapelvic cyst is known as a renal sinus cyst, because of its location. Parapelvic cyst could somtimes cause pain, an obstruction, infection, or the formation of kidney stones. Many of these cysts are left alone, but there are some circumstances like these which will lead to surgery.
Carcinomas, or cancerous masses are very easily differentiated from simple renal cysts(parapelvic cyst) by the method used in diagnosis, whether it be an ultrasound, CT or MRI.
