What are the complications of the left kidney cyst?

Generally do not have symptoms appeared early left renal cyst, cyst secondary infection, the patient showed chills, fever, back pain, may also have frequent urination, urgency or dysuria, blood culture positive urine bacterial culture can also be positive. CT scan showed the cyst CT value than the infected cyst CT value increased wall thickening of the wall after the injection of vascular contrast agents contrast enhancement (enhanced). Cysts on the kidney, the lower pole or the side edge, B ultrasound-guided or CT-guided needle aspiration of the cyst fluid to send a routine examination and bacterial culture, cavity with normal saline. General aspiration, body temperature can drop puncture again every 2 to 3 days until the capsule fluid clear, the temperature dropped to normal. Application of effective antibiotics, consideration should be given drugs cyst penetrating: penicillins, aminoglycosides and Vanguard ADM antibiotics easily into the cysts derived from proximal renal units, and not easy to enter the cyst of the distal nephron. Erythromycin, chloramphenicol, tetracycline, clindamycin, TMP is easy to enter the cyst of the proximal and distal nephron. If the cyst is repeated puncture granules with effective antibiotics, intravenous drug use is generally 2 to 3 weeks to control the infection. Such as cystic needle aspiration is an effective antibiotic to take eight weeks or longer to control.
Complications of the left kidney cyst and left kidney cyst complications of treatment:
Spontaneous infection in a simple left renal cyst is rare, and the event would be difficult to be identified with renal carbuncle. Sometimes the cyst bleeding, sudden, can cause pain, bleeding from the cyst wall associated with cancer. The cyst is located in the lower pole of kidney and close to the ureter, can exacerbate the hydronephrosis, urine on the oppression of the renal pelvis can cause back pain. This obstruction can also make kidney infection.
When the cyst complicated by infection, antibiotic treatment should be strengthened, Muther and Bennett 1980 low concentration of antibiotics that can be achieved in the cyst fluid. And they often need to pass through the puncture and drainage. This puncture and drainage fails to take the surgical excision of the cyst wall of the renal outer part and drainage, also proved to be quite good effect. Hydronephrosis occurs, removal of obstruction caused by the cyst wall can be lifted to ureteral obstruction. Pyelonephritis involving the kidney suggests the presence of urinary tract obstruction, and then the ureter drainage is not smooth. After excision of the cyst, the natural ease the urinary tract pressure so that more effective anti-bacterial treatment.
