Brief Summary

Urolithiasis is one of the most prevalent urological diseases affecting general population across the world. The available treatment modalities for renal stones are Shock wave lithotripsy (SWL), Percutaneous Nephrolithotomy (PNL), and Retrograde Intrarenal Surgery (RIRS). Irrigation for RIRS is the critical component for the success of procedure. To avoid detrimental effects of high pressure, intra-renal pressure (IRP) has to be lower. Different studies have shown that high irrigation pressure raises intra-renal pressure leading to pyelo-venous and pyelo-lymphatic reflux which can lead to sepsis and septic shock. Comparative study of different irrigation pressure during RIRS is lacking. This is randomized controlled trial conducted in Department of Urology and Renal Transplant Surgery for duration of one year. Objective of the study is to compare safety and efficacy of gravity irrigation versus pressure irrigation. Patients with symptomatic kidney stones: non lower pole stones \<2cm, lower pole stones \<1cm and lower pole stones 1-2 cm in whom PCNL is contraindicated will be enrolled in study with informed consent. Retrograde intrarenal surgery will be performed as standard procedure and Ho:YAG laser will be used to fragment stones. Stone free rate at postoperative day 1 and after 1 month will be monitored through X-ray KUB. Maximum irrigation pressure, duration of surgery, stone size, density, location, intraoperative and postoperative complications as classified by Clavien-Dindo will be noted for all patients. Data will be appropriately analyzed and statistical tests applied as necessary.
