Supine Mini- Percutaneous Nephrolithotripsy (Mini PCNL) for Renal Stones 0.5 – 2 CM in Pediatric Age Group: New Experience of TBRI

Objective To establish the new experience as well as to evaluate the safety and efficacy of mini percutaneous nephrolithotripsy (mini PCNL) in treatment of kidney stones 0.5-2 cm in pediatric age group. Patients and Methods Between December 2018 and October 2020 seventeen patients admitted to the Urology Department, presented with renal pelvis or calyceal stone (5-20 mm) were enlisted for mini PCNL. Achieving success of the technique is considered when stone free or radiologically insignificant residual fragments <4mm. Results The demographic data in this study is comparable with those in adults age group regarding the stone size with no statistical significance. Meanwhile, the operative time was 59.71 ± 19.44 min , and Fluoroscopy times had mean of 8.11 ± 2.05 min. The stone free rate was 96.2% in mini PCNL, one case of mini PCNL (5.9%) had significant bleeding and needed transfusion. One patient of mini PCNL (5.9%) had perforation in the renal pelvis which was resolved with insertion of Double J stent & nephrostomy. Conclusion Supine mini PCNL can be an effective and alternative option for treatment of renal stones 0.5-2 cm in pediatric age group. Supine mini PCNL has accepted operative and postoperative course. Larger numbers of patients will be more effective to confirm these results. Keywords: Pediatric; Mini percutaneous nephrolithotomy; Stone
