What is a cyst near pelvis ?

Pelvis beside cyst (Parapelvic cyst) also known as cysts around the renal pelvis (peripelviccyst); originated in the renal sinus , the invasion of the renal sinus cyst cyst beside named pelvis (parapelviccyst). Parapelvic cyst is caused by congenital factors , the incidence rate of renal cysts 1% to 3% , after more than 50 years to appear. Next cysts are usually solitary renal pelvis , renal histology sources or old urinary cyst. Currently known as the clinical side of the above two types of cysts renal pelvis .
Cystic renal pelvis beside initial diagnosis relies imaging , CT diagnosis of the disease is most definitely the role of , IVP examination in the diagnosis of this disease also has a high accuracy rate , can understand the bilateral renal function , renal collecting system morphology and complications of renal hilum and easy tips lesions , should be used as a routine examination . B- considered in the diagnosis of this disease is sometimes misdiagnosed as hydronephrosis, the B -scan and unexplained kidney disease should exist in the water may need further examination. CT scan showed cysts in the renal hilum , with normal renal parenchyma apart, the lowest density halo around the renal sinus fat in the cyst is composed parapelvic cysts characteristic performance , CT scan pelvis beside the cyst with hydronephrosis similar, but enhanced scan without enhancement, development of the renal pelvis , calyces pressure and stretched, the cyst can be set off more clearly.
Auxiliary examination next cyst diagnosed patients with renal pelvis . Differential diagnosis of cystic renal pelvis side as follows:
1 , hydronephrosis : hydronephrosis by the urinary system , the innate and acquired multiple factors , can occur at all ages . Patients have no obvious clinical symptoms, there may be a sense of expansion and abdominal mass waist severe hydrocephalus . Calculi in patients with intermittent hydronephrosis can cause renal colic , accompanied by nausea , vomiting , abdominal distension and oliguria and so on. Examination palpable increase in severe hydronephrosis , such as infection can occur pyuria and systemic symptoms of infection . The diagnosis relies on ultrasound , IVP, CT and MRI and so on.

2 , kidney cancer: is more common cancer of the urinary system , divided into two types of benign and malignant , benign rare. No typical clinical symptoms of benign tumor , larger waist and abdominal pain can occur when the discomfort , physical examination palpable enlarged kidneys. Typical clinical manifestations of kidney cancer is hematuria , flank pain and swelling . The diagnosis relies on ultrasound, CT and MRI and other enhancements , more performance for solid lesions , showed a cystic individual characteristics .
