Flexible Ureteroscopy and Laser Lithotripsy of Lower Pole Stones

After performing flexible cystoscopy the surgeon accesses the renal system with a flexible ureteroscope. The stones are relocated using a stone basket to ensure safe laser lithotripsy in the upper pole. Stone treatment is performed with a Holmium:YAG laser. Residual fragments are removed using a 6-wire nitinol basket.

Reason for Ureteroscopy:

  • Stone-free right side
  • Left kidney:
    • Distal lower pole 10 mm stone, 1066 Hounsfield units
    • • Cranial in the lower pole 6 mm stone, 805 Hounsfield units

Postoperative Information:

  • JJ removed after 1 week
  • Uncomplicated recovery
  • Stone analysis
    • Whewellite 25% calcium oxalate 1 H2O
    • Whewellite 15% calcium oxalate 2 H2O
    • Apatite 60% calcium hydroxyphosphate
