Background: Ureterorenoscopy is considered the standard treatment in the management
of urolithiasis with pneumatic lithotripter and holmium: YAG (Ho: YAG) laser.
Aim: To assess efficacy and safety of holmium: YAG
(Ho: YAG) laser lithotripsy in comparison with pneumatic lithoclast during
retrograde ureteroscopy for the management of ureteric calculi of different
Data was collected by recruiting 100 patients
of ureteric stone disease admitted in urology department Shaikh Zayed Hospital
Lahore, from 25-02-16 to 15-08-16. All ureteric stone patients of both genders
included in this study were in the age range of 18 to 60 years having stone
size upto 1.5cm.
Results: Stone free rate in Ho: YAG laser group was 94% whereas it was 72% in
pneumatic lithoclast group. The difference in the stone free rate was more
marked for stones greater than 10 mm of size (80% versus 47.4%, P = 0.07).
Overall complication rate was 7.9% (Clavien II and IIIb). There was no
complication found with Holmium: YAG laser. The complication rates were not
dependent on the size of stone.
Conclusion: The use of the Ho: YAG laser in ureteroscopy appears to be a better tool
to disintegrate ureteral calculi independent of stone size.
