CT-guided percutaneous nephrostomy and ureteroscopic holmium laser lithotripsy in treatment of complex renal calculi: a report of 32 cases / 中华全科医师杂志

ABSTRACT

From August 2007 to January 2009 a total of 95 patients with complex renal calculi were treated with CT ( n = 32 ), X-ray ( n = 33 ) or ultrasound ( n = 30 ) guided percutaneous nephrostomy and ureteroscopic holmium laser lithotripsy respectively. The CT guided procedure had lower positioning time,positioning failure rate, complication rate and residual stone rate than those of X-ray and ultrasound localization, particularly had advantages in the stone clearance rate and complications rate ( all P ＜ 0. 05 ).CT guided localization can be chosen in the following conditions higher kidney position, large staghorn calculi or renal pelvis stones without hydronephrosis, with congenital renal malformations or failure of ultrasound or X-ray localization.
