Abstract
Introduction: Percutaneous nephrolithotomy (PCNL) has almost completely replaced open surgery for kidney stones because of continuous advancements in the method since the first PCNL was performed in 1976. The aim of this study is to compare the characteristics and outcomes of adult patients and pediatric patients who had undergone PCNL.Methodology: A retrospective study was conducted at the Sindh Institute of Urology and Transplantation (SIUT) Hospital in Karachi, Pakistan. It included the data of patients who underwent PCNL from January 2015 to January 2022 at the SIUT hospital. The primary outcome variable was the stone-free rate (SFR). Secondary outcomes included length of hospital stay, and complications were assessed using modified Clavien classification systemResults: There is no significant difference in the SFR at discharge between pediatric and adult patients (86.67% vs 88.69%, p=0.634). There is no significant difference between the two groups in relation to the total length of hospital stay (p=0.446). Moreover, 12.50% and 11.11% of adults and children developed complications, respectively, after the procedure. The percentages are not significantly different between the two groups (p=0.266).Conclusion: The current study using standardized and consistent PCNL techniques shows that SFR is similar in both adults and children, and there is no difference in complications between adults and children.

Summary
The aim of this study is to compare the characteristics and outcomes of adult patients and pediatric patients who had undergone PCNL. Percutaneous nephrolithotomy (PCNL) has almost completely replaced open surgery for kidney stones because of continuous advancements in the method since the first PCNL was performed in 1976 [1]. Despite the advantages of PCNL over open surgery, the rates of complication for this procedure remain high [2]. The other major concern in children is avoiding the retreatment need. The ideal treatment needs to be minimally invasive with a lower retreatment rate and high stone clearance
