Purpose
To describe our experience in the use of percutaneous nephrolithotomy (PCNL) as a primary treatment for paediatric kidney stones and to highlight its benefits.
Methods
The design was retrospective and observational. All the children treated for kidney stones from 2011 to 2021 were included. The population was divided into Group A (PCNL) and Group B (retrograde intrarenal surgery, RIRS). The outcomes were stone-free rate (SFR), the rate of procedures per patient, the rate of failure and the rate of complications.
Results
Twenty-eight patients with 33 kidney units were included. Eighteen of them (64%) were males. The median age was 10 (IQR 6.8–13) years. Forty-seven procedures were performed. Twenty-four of them (51%) were mini-PCNL. Group A included 17 patients (61%). Group A presented a higher SFR (p = 0.007) and a lower number of procedures (p < 0.001). RIRS failed in five cases (45%) because of non-compliant ureter. Two urinary tract infections (UTI) were reported after PCNL and four UTIs after RIRS (p = 0.121). No major complications were reported.
Conclusion
Mini-PCNL should be suggested as a primary approach for pediatric kidney stones. This technique presented a better effectiveness with a reduced number of procedures when compared to RIRS.
