Ultra Mini Percutaneous Nephrolithotomy VS Stented Extracorporeal Shock Wave Lithotripsy for Stone Management

Nephrolithiasis is the third most common disease of the urinary tract. As minimally invasive technologies develop, shock wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS), and percutaneous nephrolithotomy (PCNL) are different surgeries to treat renal stones. Aim of the Study is to compare results, safety and outcome of Ultra mini PCNL versus stented extracorporeal shock wave lithotripsy (SWL) for the management of renal calculi from 10 - 20 mm. Patients were randomized to either Ultra-Mini-Percutaneous nephrolithotomy group or stented SWL group via the closed envelope method. Patient data was collected preoperatively, immediately postoperatively and 2 and 4 weeks postoperatively to assess operative time, hospital stay, complications regarding fever, hematuria and need for blood transfusion, residual stones and need for retreatment.
