Polycystic kidney what inspection should do?

Laboratory tests
1. A urinalysis often pyuria (94%) and hematuria (43%) and proteinuria (93%), pipe type, urine (11%), urine specific gravity in 1.010 below 40%, pyuria is urine culture can be found, such as e. coli late renal insufficiency.
2. The blood test when accompanied by infection routine blood can have increased leucocyte heighten, neutral classification, late kidney not full-time urea nitrogen, creatinine, increased.
Imaging studies
1. Imaging examination including X-ray abdominal plain film, CT and MRI examination, imaging examination [vein angiography (IVP) of the renal pelvis, ureter renal pelvis angiography and radionuclide imaging] as the routine inspection method. Do pelvic angiography of the disease (if lack of kidney excretion function, it must be retrograde urethrography) check, can be found early because the calyces oppressed by cyst, see the calyx end half moon shape deformity; Late calyces are stretch of the renal pelvis, calyces broadening, boundary obviously. Other tests such as abdominal X-ray plain film is visible on both sides of the kidney size change obviously, and the sample has a cyst or calcification shadows.
CT and MRI are generally not as the initial inspection method, for receiving radiation amount is larger, the price is more expensive. But its advantage is able to display the organization of different density, providing detailed anatomy, CT can better clear the location and nature of the disease, is a helpful method of inspection. It is instead of traumatic retrograde and imaging of the renal pelvis. As well as CT, MRI and more clearly show the tissue density, clear obstruction etiology and pathological change nature.

2. Ultrasound ultrasound in the diagnosis of renal pelvis calyces expand very effective, it is in the diagnosis of renal capsule and hydronephrosis priority check method. Since this is a non invasive examination, has high sensitivity to the diagnosis of renal capsule sex change, is also suitable for inspection of polycystic kidney. Ultrasound examination can be found that increased renal size, cysts, renal pelvis, calyces often significant deformation, otherwise the cyst wall thicker or different degrees of calcification and obstruction. Ultrasound can also be used for the screening of this disease.
