Summary

This comparative study aims to compare and assess the safety, efficacy, outcome, feasibility, intraoperative and postoperative complications of one-shot dilatation versus serial dilatation techniques for access during percutaneous nephrolithotomy for management of renal stone disease in adult patients.

Conditions

• Percutaneous Nephrolithotomy (PCNL)
• Renal Stone Disease

Interventions

Type	Name	Description
PROCEDURE	renal dilatation by one-shot dilatation technique	renal dilatation was done by one-shot dilatation technique using 30Fr Amplatz dilator directly over the central Alken rod.
PROCEDURE	renal dilatation by metallic telescopic dilators (Alken).	insertion of the Alken guide followed by a telescopic dilator between 9Fr to 30Fr, then an Amplatz sheath 30Fr was advanced over the dilator which was then removed, leaving the Amplatz sheath in the collecting system
PROCEDURE	renal dilatation by sequential fascial dilators (Amplatz)	sequential renal dilatation with Amplatz dilator set was used
