Abstract:
In the past several decades there has been a remarkable development of small-caliber, flexible ureteroscopes and various ancillary instruments for stone manipulation and retrieval. Percutaneous antegrade ureteroscopy can be substituted in select cases for retrograde ureteroscopy. We report a case of a 60-year-old man with severe ankylosis in both hip joints who was diagnosed with bilateral ureteral stones. The patient underwent antegrade flexible ureteroscopy and laser lithotripsy. This case illustrates the role of antegrade flexible ureteroscopy combined with the holmium:YAG laser as a minimally invasive, safe, and effective technique for the management of stones in a patient who cannot undergo a retrograde approach.
