Effectiveness of US-Guided PCNL Different Positions in Renal Stones Treatment

Completed

• Conditions: Ultrasound Therapy; Complications; Renal Stones; Percutaneous Nephrolithotomy
• Interventions: Procedure: Supine percutaneous nephrolithotomy group; Procedure: Flank suspended supine position percutaneous nephrolithotomy; Procedure: Prone percutaneous nephrolithotomy group

• Registration Number: NCT05855057
• Lead Sponsor: Benha University

Brief Summary

The aim of this study is to compare the effectiveness of Ultrasound-Guided Percutaneous nephrolithotomyin different positions supine, prone positions and flank suspend supine position in renal stones treatment.

Detailed Description

Percutaneous nephrolithotomy (PCNL) has become the choice of modality for the treatment of large and complicated renal calculi. Initially, percutaneous access to the kidney was only performed in the prone position, as described sixty years ago.

Secondary Outcome Measures

Name	Time	Method
Stone-free rates	48 hours Postoperatively	Comparison of the percentage of patients achieving complete stone clearance among the different positions.
Operative time	Intraoperatively	duration of the Ultrasound-Guided Percutaneous Nephrolithotomy (PCNL) procedure among different positions
Complication rates	48 hours Postoperatively	Comparison of postoperative complications (e.g., bleeding, infection, injury) among the different positions.
