Never Mix up the Diagnosis of PKD and Other Diseases

Multiple cysts is clinical infectious nephropathy. And clinical manifestations are BLD, lumbago and so on. Experts remind us that never mix up the diagnosis of PKD and other diseases. we need to distinguish multiple cysts and following diseases.
1. Two kidney seeper caused by congenital disorder or the block of acquired ureteral:
Two kidney seeper has such symptoms of phyma in bilateral sides of waist and damage of kidney function. While pelvic vein angiography and ultrasonic test show that these symptoms have much difference in multiple cysts.
Disease is very rare, but it seems like multiple cysts in urogram. In multiple cysts, if one side kidney is small or urogram doesn’t show the twist, it will be difficult to distinguish kidney neoplasms in the other side. Neoplasms often confined to a certain part of the kidney, while cysts in PKD cover all of the kidney. The whole renal function in unilateral renal tumors is normal, while the multiple cysts is always got damaged. Nuclear magnetic resonance or renal angiography can distinguish these two diseases. Scintillation scan or ultrasonic test is also helpful for the distinguishing.
In this disease, renal cysts or adenocarinoma of these two kidneys can develop progressively. Urography or renal ct x-ray photography can reveal multiple cysts, and then we can make a definite diagnosis based on the other symptoms. Nuclear magnetic resonance, angiography, ultrasound image or flash photography can guarantee the diagnosis.
Adenoma sebaceum involves skin, brain, retina, skeleton, liver, heart and kidney. Renal lesion is always multiple and bilateral. Under the microscope, we can find angiolipoma. In the end of kidney failure (uremia), urography presents it as cystic kidney, and we can distinguish it by other symptoms, nuclear magnetic resonance and ultrasound.

2. Bilateral renal tumor: 
3. Von Hippel-Lindau disease ( cerebellum hemangioma cyst, retinal angioma and pancreatic tumor or cysts):
4. Tuberous sclerosis (clonic convulsions, mental retardation and adenoma sebaceum):
