Simple renal cysts in children: diagnosis and follow-up with US.

Abstract

To assess the sonographic frequency of simple renal cysts in children, the authors retrospectively reviewed the results of abdominal sonographic studies of 16,102 children performed over a 5-year period between January 1, 1985, and December 31, 1989. Patients with abnormal renal function, dysplastic kidneys, or a family history of polycystic kidney disease were excluded from the study. The authors' review of the sonograms revealed 37 simple cysts in 35 patients (0.22%); the cysts were evenly distributed by age and sex and measured from 0.3 to 7.0 cm in maximum diameter. Sixteen cysts (43%) were in the upper pole of the right kidney. Follow-up sonographic studies of 23 cysts in 22 patients for up to 5 years showed no change in size in 17 cysts (74%). The largest cyst was drained percutaneously; all other cysts were managed conservatively. No patient showed deterioration of renal function. Therefore, the authors concluded that in a pediatric patient demonstrating normal renal function, no further intervention is necessary when a simple renal cyst is identified at sonography.

Unified Criteria for Ultrasonographic Diagnosis of ADPKD

“…This finding is consistent with previous data for at-risk PKD1 individuals 15 or for individuals who underwent ultrasonography for nonrenal indications. 19,20 Nonetheless, 2.1% (three of 144) and 0.7% (one of 144) of the genetically unaffected cohort younger than 30 yr had one and two renal cysts, respectively. These data highlight the need for using more stringent criteria such as three or more (unilateral or bilateral) renal cysts to minimize false-positive diagnoses in this age group.…”

Simple Renal Cortical Cysts in Children: Two Uncommon Case Reports

“…(The average diameter of the cysts in the study of Gordon was 3.5 cm.) In a more recent article published by McHugh et al [4], it was found that the incidence of renal cysts in children, as detected by US, was 0.22%. In that particular study, the authors reviewed retrospectively 16,102 abdominal US examinations of children aged between birth and 18 years.…”

A General Overview to the Treatment of Cystic Renal Diseases and Innovations in the Treatment: Review

“…Sağ-lıklı çocukların %0,3'ünde basit böbrek kisti vardır. 61 Renal kistlerde, bilgisayarlı tomografi (BT) görüntü-leri için hazırlanan, ancak MRG ve ultrasonografi (USG) de kullanılabilen Bosniak renal kist klasifikasyon sistemi geliştirilmiştir (Tablo 1). [62][63][64] Bu sistem, BT'de görülen renal kistteki sıvı dansitesine, kistin duvar ve septa kalınlığına ve kist duvarında kalsifikasyon olup olmamasına dayanmaktadır.…”
