The Pathogenesis and Pathological Changes of Kidney Cyst

It is still not clear that whether simple kidney cyst is geneogenous or acquired. The pathogenesis of kidney cyst is similar to that of polycystic kidney disease, but they have different severity extent.

On the other hand, the obstruction and ischemia of kidney tubules can result in simple kidney cyst. It means that kidney cyst can be acquired. As cysts are becoming bigger, the stress can damage renal parenchyma, but the renal function is not damaged. If a cyst unfortunately stresses the ureter, it can lead to progressive hydronephrosis and then infection.

Simple kidney cyst can affect the lower pole of kidneys. If kidney cyst patients have symptoms, the kidney’s diameter is 10 cm on average with rare cases in which the cyst can expand to fill the whole flank. Simple kidney cysts often occur on the surface of kidney, and it sometimes in the deep part.

When cysts are in deep part, the cyst wall will connect with epithelium of pelvis and kidney calices. It is difficult to separate them. Microscopic examination result will show that the cyst wall has severe fiber modification and hyaline degeneration, sometimes calcified part can be found and the neighbor renal tissues under stress have undertaken fiber modification. It is reported that many simple kidney cyst diseases fall on children, but large cyst is rare in children. At this point, we have to consider whether it is tumor, for it is difficult to make a distinction between multilocular cyst and tumor in the IVU. It can be diagnosed through Ultrasound images, occasionally CT and MRI.

Though kidney cyst is often not a big problem, we have to take care of it, especially when the cyst is more than 5 cm in diameter. Western therapy like Puncture Sclerotherapy operation can remove the cyst temporarily, but it relapses all the time. In contrast, Micro-Chinese Medicine Osmotherapy can treat kidney cyst fundamentally. The effective elements in the medicine inactivate the epithelial cells of the cysts, make them lost the secretion activity, and stop the sac liquid from secreting. In this way, the cyst will stop growing. At the same time, we will use medicine to increase the blood circulation in the cyst surface and absorb the sac liquid back. Finally, the sac liquid is discharged out of the body through metabolism.
