The First Experience of Using Retrodrade Intrarenal Surgery in the Treatment of Calyceal Diverticul in Children

Calyceal diverticulum is a difficult to diagnose and quite rare disease in childhood. The incidence of calyceal diverticula ranges from 3.3 to 4 cases per 1000 children. The gold standard for diagnosis is computed tomography with intravenous contrast. All diverticula whose dimensions exceed 2.5 cm or more are subject to surgical treatment due to the risk of developing a urinary tract infection, pain and possible stone formation. A modern and promising treatment method is retrograde intrarenal surgery. The article presents the first case of using retrograde intrarenal surgery (RIRS) for the treatment of calyceal diverticula in children. This case demonstrates the use of retrograde intrarenal surgery in the treatment of calyceal diverticula in 15 patients observed in the Department of Urology of the N.F. Filatov Children's City Clinical Hospital from 2022 to 2024. Retrograde intrarenal infundibulotomy was performed in fifteen patients with calyceal diverticula. This method is minimally invasive and highly effective. Retrograde intrarenal surgery is a minimally invasive, modern and promising treatment method that is being actively implemented by urologists in their practice.
