Exclusion criteria

Exclusion criteria: Patients with anatomical abnormalities Pregnant patients Active urinary tract infection (UTI) Patient with uncorrectable coagulopathy Stone size more than 20 mm

Design outcomes

Primary

MeasureTime frame
The study is expected to identify specific preoperative and intraoperative factors that independently predict stone free rate following retrograde intrarenal surgery for renal stones less than 20 mm Timepoint: 2 WEEKS—

Secondary

MeasureTime frame
Delineate independent predictors of residual fragments less than 5 mm thereby aiding in the identification of patients at higher risk of incomplete clearance after a single RIRS session The findings are expected to provide clinically relevant data to optimize patient selection procedural planning and counseling regarding the likelihood of stone clearance and the potential need for auxiliary proceduresTimepoint: 2 WEEKS—
