Comparative study between ultra-mini-percutaneous nephrolithotomy versus stented extracorporeal shock wave lithotripsy for treatment of renal stones in Egypt

Objectives The purpose of this study is to compare results, safety and outcome ultra-mini-percutaneous nephrolithotomy (PCNL) versus stented shock wave lithotripsy (SWL) for the management renal calculi sized 10–20 mm.Methods This was conducted at Urology Department, Faculty Medicine, Ain Shams University. After meeting inclusion exclusion criteria, 90 patients were randomized either ultra-mini-PCNL group or SWL through closed-envelope technique, with 45 in each group. Patient data collected preoperatively, immediately postoperatively 2 4 weeks assessing operative time, hospital stay, complications including haematuria, fever, need blood transfusion, residual stones retreatment.Results Stone-free rate (SFR) higher compared group, no statistically significant difference P-value = 0.316. As retreatment, it slightly yet insignificant 0.681.We found between both groups regarding post-operative haematuria respectively.Operative time stay significantly < 0.001 both.Conclusion Both are good treatment choices less than cm low complication rates. Stone size indices predictor retreatment. Further studies SFR based on stone interventions needed.
