Outcome Measures
Primary Outcomes (1)
Stone clearance rate
Comparison of stone clearance rates among different positions (flank suspended supine, supine, and prone) in Ultrasound-Guided Percutaneous Nephrolithotomy (PCNL) for the treatment of renal stones.

Study Arms (3)
Flank suspended supine position percutaneous nephrolithotomy
This group included 41 patients in flank suspended supine position percutaneous nephrolithotomy.
Supine percutaneous nephrolithotomy group
This group included 41 patients in supine percutaneous nephrolithotomy.
Prone percutaneous nephrolithotomy group
This group included 41 patients in prone percutaneous nephrolithotomy.
Interventions
The patients will be placed in the supine position with the shoulder and the buttock will be raised by a 3-l bag of water suspending the flank of the affected side. The body contour will be aligned to the edge of the table. The operating table will be adjusted to the jack knife position, with the tip of the lower part of the table will be slightly lowered. The leg of the affected side of the patent will be straightened dorsally flexed and slightly inner rotated, with the knee of the other side will be flexed. The patients will be then immobilized at the chest and the pelvis with two adherent tapes which crossed each other at the abdomen to form a 'V' shape.
The patient will remain in the supine position, with the side of interest at the edge of the table, with a small cushion placed under the flank to elevate it 15-20°.
Prone percutaneous nephrolithotomy. The prone position (PRON) technique followed these classic steps: patients will be placed in a lithotomy position and a ureteral catheter will be inserted through a rigid cystoscope to perform a retrograde pyelogram. The ureteral catheter will be fixed to a Foley catheter, and then the patient will be repositioned to the prone position with pads under their shoulders.
