Brief Summary

Urinary stone disease is a common urological condition that affects millions of people worldwide, often leading to significant morbidity and healthcare costs. Medium-sized renal stones, typically defined as stones measuring 1 to 2 cm in diameter, pose a particular challenge in management. These stones are large enough to potentially cause significant obstruction and symptoms, yet their size and location make selecting an optimal treatment modality crucial for achieving favorable outcomes with minimal complications. Historically, open surgery was the primary intervention for large or complex stones. However, the advent of minimally invasive techniques has revolutionized stone management, allowing for more effective and patient-friendly approaches. Among these, Super-mini percutaneous nephrolithotomy (SMP), flexible uretero-renoscopy (F-URS), and shock wave lithotripsy (SWL) have emerged as minimally invasive modalities for managing medium-sized renal stones. This study aims to evaluate the outcomes; safety, efficacy, and complications associated with SMP versus F-URS Versus SWL in the management of reanl stones 10-20 mm in diameter.
