Flexible Ureteroscopy and Laser Lithotripsy of an Obstructing Stone

After placing a guidewire the flexible ureteroscope is backloaded on the wire. The surgery is performed without a ureteral access sheath. After stone fragmentation residual fragments are retrieved from the ureter using stone baskets, and a stent is put in place to ensure sufficient drainage.

Reason for Ureteroscopy:

Obstructing ureter stone right side, placement of JJ stent two weeks previously.

  • Uncomplicated
  • JJ removed seven days post-surgery
  • Stone analysis:
    • 50% calcium oxalate 1 H2O
    • 45% calcium oxalate 2 H2O
    • 5% calcium hydroxyphosphate
  • Stone-free on ultrasound six weeks post-surgery. No hydronephrosis.
