Antidiastole And Treatment Of Pediatric Calyceal Diverticulum

Methods: From January 2009 to February 2017,44 patients with renal cystic disease were analyzed retrospectively.7 were diagnosed as renal calyceal diverticulum.We retrospectively reviewed their imaging data,treatments and outcomes.Results: There were 4 boys and 3 girls with an average age of 6.4(0.3-10)years.The involved sides were right(n =5)and left(n =2).Three cases presented with abdominal pain while another 4 asymptomatic cases were diagnosed by ultrasound.The average diameter of calyceal diverticulum was 3.8(1.4-6.2)cm.Four cases were followed-up without any treatment one received antiinfective treatment and another 2 cases underwent laparoscopy.The follow-up time ranged from 3 mouths to 8 years.The lesions stabilized in size and remained asymptomatic in 5 conservatively treated cases and 2 cases undergoing laparoscopy had neither complications nor recurrence.Conclusion: Pediatric calyceal diverticulum may be easily confused with simple renal cysts.And delayed post-contrast computed tomography ishighly sensitive in its diagnosis.
