Percutaneous Nephrolithotomy, Renal Stones, Ultrasound Therapy; Complications
Conditions
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.
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.
