Renal cysts often are not large in size and do not show any symptoms, which cause no affect on the function of kidneys. No obvious pathological changes will occur because they grow very slowly, so there’s no need for treatment generally. However, sufferers should have routine test about once a year or half a year. For a 4cm or larger cyst, the follow up treatment such as puncturing, can be considered which will drain the cyst and then fill with a solution containing anhydrous alcohol to make the tissue harder for fear of the recurrence of it.
Before the surgery, the preoperative platelet count, time of bleeding and
clotting should be checked. Then, puncturing the cyst with a long needle
inserted into the skin under the guidance of ultrasonography. After the fluid is
pumped out, filling the cyst with a solution containing anhydrous alcohol, and
the volume of the solution should be just 1/4 of the pumped fluid. Patients
should change their position to make the complete touch between solution and
cyst wall. The solution should be pumped up 5 minutes after the operation.
Patients should have reexamination 1 month after the operation.
If the cysts get secondary infection, patients will present symptoms such as
chills, fever, backache, frequent urination, urgent urination or urodynia. And
their blood culture and urine culture can both be positive. CT value will be
higher than that of non-infectious cyst. The cyst wall will broaden and it will
present enhanced development when injected into vascular contrast medium.
If patients with renal cyst on the upper or lower pole of kidney, their cyst
fluid should be pumped out under the guidance of B-ultrasound or CT and then be
checked regularly, cultivated. And then, use normal saline to wash the cyst
cavity. Generally, the body temperature will decrease, and then puncture and
wash the cyst cavity after 2 or 3 days till the fluid is clear, and the
temperature will be back to normal again.
At the same time, taking the effective antibiotic and their permeability
should be considered. Medicines like penicillin, aminoglycoside, and
cephalosporin can easily permeate into cysts on the remote nephrons and hardly
permeate into the cysts on the remote nephrons. However, erythromycin,
chloramphenicol, tetracycline, clindamycin, TMP are easy to go into all the
Generally, the process of puncturing and washing with the combination of
effective antibiotics for a few weeks can control the infection. If the cyst can
not be punctured, it will take about at least 8 weeks effective antibiotics to
