Purpose: To assess the safety and efficacy of an ultramini nephrostomy tract, which we were using for the first time, combinedwith flexible ureterorenoscopy (URS) in the treatment of pediatric patients with multiple renal calculi. Materials and Methods: Twenty pediatric patients (age, ≤6 years) underwent ultramini percutaneous nephrolithotomy (PCNL)combined with flexible URS. The group had multiple renal calculi, which were bilateral in 3 cases and were located in a total of 23sites. The calculi were located in 2 calyces in 10 cases, scattered in more than 2 calyces in 7 cases, and limited to 1 calyx in 3 cases. The average patient age was 37.35 months (range, 14–68 months). The average stone diameter was 2.0 cm (range, 1–3.0 cm). Inall patients, an ultramini nephrostomy tract was established under ultrasound guidance (dilated to F10) with simultaneous sheathplacement. The flexible URS was placed into the collecting system during holmium laser lithotripsy. Results: When ultramini PCNL was combined with flexible ureterorenoscopic holmium laser lithotripsy, the complete stone-freerate was 87% (20/23). The average level of hemoglobin decreased to 1.0 g/dL after the operation. No blood transfusions wereneeded. Levels of blood urea nitrogen, creatinine, and C-reactive protein were not significantly different before and after the operation. The average duration of hospitalization was approximately 4.85 days, and all cases were followed up for 6 to 12 months. No complications were found. Conclusions: Ultramini PCNL combined with flexible ureterorenoscopic holmium laser lithotripsy is a safe and effective treatmentfor children with multiple renal calculi.
