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.
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.
A total of 73 patients were diagnosed as having parapelvic renal cysts by ultrasonography, in combination with computed tomography, and/or drip infusion urography in our Department. The background to diagnosis was suspicion of hydronephrosis in 15, flank and/or back pain in 15, and macroscopic hematuria and/or occult blood urine in 12.
parapelvic cyst are also called renal sinus cyst, pelvic cyst, peripelvic cyst or parapelvic lymphangiectasia. Parapelvic cysts are a rare form of simple renal cysts, and they are much more commonly associated with the symptoms of obstruction, pain, infection and stone formation. Surgical management is usually done for big cysts, lumbar pain, hematuria, hypertension and other complications. Otherwise there is nothing to be worried about. If you are more comfortable with discussing this further with a nephrologist, it is your prerogative, and don't forget to bring your ultrasound and ct scan results for his evaluation.
