Mini- Percutaneous Nephrolithotomy Versus Standard Percutaneous Nephrolithotomy in the Treatment of Renal Stones.

Mini- Percutaneous Nephrolithotomy Versus Standard Percutaneous Nephrolithotomy in the Treatment of Renal Stones. A Randomized Controlled Trial

The EUA Urolithiasis Guidelines Panel meta-analysis suggest that mPNL is at least as efficacious and safe as sPNL for the removal of renal calculi. However, the quality of the evidence was poor, drawn mainly from small studies, the majority of which were single-arm case series, and only one of which was RCT. The risks of bias and confounding were high, highlighting the need for more reliable data from RCTs. So, the Panel recommended for more clinical research .

The aim of this study is to compare between PNL and mPNL through a randomized controlled trial.
