Abstract

Renal cyst is a common renal disease. It rarely produces symptoms, and thus rarely require treatment. But the treatment is necessary when the cyst is symptomatic or complicated. The possible approach includes surgical unroofing or cyst puncture with or without intracystic injection of sclerosing agents. Thus we evaluated the efficacies of treatments in renal cystic disease. Cystic diseases were treated with percutaneous aspiration in 18 cases, percutaneous aspiration with sclerosing therapy in 26 cases. Overall efficacies were 22.2% with aspiration only and 95% with combined sclerosing therapy without no specific complications. Sclerosing therapy is relatively safe, less hazardous to the patient and shows high success rate in the treatment of cyst. We concluded that combined percutaneous cystic aspiration and sclerosing therapy was the best treatment of renal cystic disease. We assessed cystic fluid of 34 cases of simple renal cyst and 3 cases of polycystic kidney. The cystic fluid were analyzed for color, lipid profile, glucose, lactic acid dehydrogenase, amylase, electrolytes, culture and cell cytology. All aspirates of simple cyst were similar to composition of transudate. But aspirates of polycystic kidney were different from simple cyst.
