Pnl Technique
The patients were placed in the lithotomy position, and following the
insertion of a semirigid ureteroscope (Karl Storz 9-11F, Tuttlingen,
Germany) and a sensor guide (PTFE-Nitinol Guidewire with Hydrophilic
Tip, Boston Scientific, Marlborough, USA) an open-ended ureteral
catheter rwas placed under fluoroscopy guidance. After placing the
patients in the prone position, retrograde pyelography was performed,
and a percutaneous insertion needle was inserted into the appropriate
calyx.Under guidance,28-F Amplatz dilatation (Geotec, Ankara, Turkey)
was applied to all patients.Stones were reached using a nephroscope
(Karl Storz 26F, Germany), and the stones were fragmented with
pneumaticlithotripsy (Elmed, Vibrolith Plus, Turkey). The fragmented
pieces were removed from the kidney with stone forceps. A 14-F or 16-F
nephrostomy tube was placed in all patients. After fluoroscopy control,
antegrade pyelography was performed, and the procedure was terminated.
