Two years follow-up of patients with asymptomatic simple renal cysts

ABSTRACT

The kidney is one of the most common sites in the body for cysts. The incidence of asymptomatic simple renal cysts ranged between 11.9% in one series up to 14% in another series of patients. The aim of this study is to follow up patients with asymptomatic renal cysts to evaluate the natural history and development of complications over 2 years follow up. The study included 131 patients, twelve cases had no sufficient period of follow up [lost follow up]. The remaining 119 patients [69 males and 50 females] ranging in age from 25-75 years were followed up at 3 months interval for a period ranging from 9-24 months [mean 16.8 +/- 04 months]. The patients were followed up by clinical history, examination, urine analysis, blood urea, serum creatinine and abdominal Ultrasonography. The results revealed that the cyst size increased with time but there was no significant difference between mean size of the cyst at presentation and at the follow up visit [P. value 0.34]. there is no change in the number of cysts and no cyst complications observed over the follow up period
