Summary

This study investigated a previously unassessed operating position for ureteroscopic holmium laser lithotripsy in patients with upper ureteral stone. The reverse Trendelenburg position can reduce migration and improve the stone free rate (SFR). Moreover, less utilization of flexible ureteroscope and hospital stay in reverse Trendelenburg position can reduce the medical cost. Therefore, it can be safely used as an optional surgical method for the treatment of upper ureteral stones.

Conditions

  • Ureterolithiasis
  • Ureter Stone
  • Ureter Calculi

Interventions

PROCEDURE

Ureteroscopic lithotripsy

After combined spinal and epidural anesthesia, patients were subjected to low pressure perfusion; The semirigid ureteroscope was passed through the urethra to the bladder, after which both ureteral orifices were observed. A 0.035 "soft-tipped guidewire was sent through the ureter orifice and reached the renal pelvis. Subsequently, the patients were placed in the reverse trendelenburg position by leaning 10 ° or 20 ° with their head up and hips down or standard lithotomy position. The ureter stone was accessed with a semirigid ureteroscope. A 273 micron Holmium: yttrium-aluminum-garnet (Ho: YAG) laser was applied as an energy source set at 1.0 J and a speed of 8-10 Hz.
