Abstract
Introduction and Objective:
In this video, we intend to analyze the feasibility, safety, and technical modifications of microperc in toddlers and preschool children younger than 5 years.
Materials and Methods:
Six children younger than 5 years, who underwent microperc, were analyzed retrospectively with respect to demographics, operative, postoperative, and follow-up data. After 5F ureteral catheterization, appropriate caliceal access was achieved using ultrasound and fluoroscopy guidance, and then, a three-way connector that connects saline irrigation tube, a 272-μm laser fiber, and a 0.9-mm flexible microperc telescope were attached to the needle. If intrarenal manipulations from one calix to another are required, an 8F “mini-microperc” sheath was placed. Ureteral catheter was removed along with the Foley catheter on the first postoperative day. All children were followed up at 1 month with ultrasonography and X-ray KUB.
Results:
The mean patient age was 3.66 years (11 months–5 years). The mean stone size and stone density was 12.80±3.71 mm and 1020±370 HU, respectively. The mean operative time was 38.34±8.16 minutes. The mean hospital stay was 48.41±28.31 hours. The mean hemoglobin drop was 0.53 g/dL. One child required nephroscopy in view of the residual gravel after 2 days. One child had grade 1 Clavien complication (fever). Complete clearance was obtained in all children at 4 weeks of follow-up.
Conclusions:
The high stone clearance rate, lower risk of ureteral trauma, and lower need for prolonged postoperative ureteral stenting make it an attractive and viable alternative in children.
