Abstract

Abstract:

Objective

To evaluate the safety and efficacy of totally ultrasonography-guided percutaneous nephrolithotomy (PCNL) in the treatment of upper urinary calculi in children (age<14 years).

Methods

The data of 231 children with upper urinary tract stones treated with PCNL between January 2010 and December 2019, 134 boys and 97 girls. The mean age and BMI of the patients were (6±4) years and (17±4) kg/m². The mean stone size was (107±69) mm². 121 cases was performed mini-PCNL (MPCNL) and 110 cases super-mini-PCNL (SMP).

Results

231 patients received 243 times of PCNL, 12 of them bilateral. The mean operative time was (71±34) mins. The mean hemoglobin decreased was (8.7± 8.5) g/L. Complete stone clearance of postoperative 48-hour and 1-month follow-up was 88.1%(214/243) and 89.3%(217/243), respectively. Significant complications were observed in 47 children, 33, 11 and 3 cases in Clavien grade I, grade II and grade Ⅲ, respectively. The mean hospital stay was (6.0±3.4) days.

Conclusions

This study demonstrated that ultrasoundguided PCNL was safe and effective.
