Ultrasonic Investigation of Simple Renal Cyst in Patients without RelatedClinical Symptoms

Background and Objectives: Simple renal cysts are more common with increasing age patients without related clinical symptoms. This was a preliminary study performed to determine the prevalence of this condition and to compare the results of ultrasound findings in patients with acquired renal cystic disease due to chronic renal failure as well as in patients with transplanted kidney. Materials and Methods: The study was performed prospectively from July to November 2000 in 1,103 patients referred to Imam Khomeini Hospital, Amiralmoʹmenin Hospital and Azerbaijan Radiologic and Sonologic Clinic for abdominal sonography to investigate symptoms unrelated to urinary tract. Results: Among 1,103 patients ,113 were found to have at least one simple renal cyst . This condition was primarily more frequent in those aged 70 years and over (27%), followed by patients who were in 60-69 years old (14.4%) age group. Conclusion: According to the findings of our study prevalence of simple renal cyst in patients having no prior clinical symptoms was less than as reported in some other studies , but is comparable to other references. The result of this study also shows different prevalence rate among various age groups with significant statistical figures ( p < 0.01 and CI = 99% ).
