“…The invention of laser in the world is credited to Theodore Mainman [21] in (1960), who used a ruby laser. In 1968 Mulvaney [22] succeeded in fragmenting a urinary system stone using ruby laser, however because of extreme warming of ruby laser during procedure, ruby laser could not be introduced into clinical use. With advancing technology, alternative laser applications with different energy sources have been performed.…”

Objective: We aimed to compare the effectiveness of holmium YAG laser and pneumatic lithotripsy in the treatment of ureteral stones. Material and methods:A total of 216 patients who had established indications of ureteroscopy between November 2011 and June 2012 were included in this study. Patients' files were retrospectively reviewed by dividing cases as groups that underwent pneumatic (PL) or laser lithotripsy (LL) procedures. Age, sex, stone burden and localization, duration of follow-up, operative times were evaluated. Stone-free rates were evaluated by ureteroscopical examination, postoperative scout films and ultrasonography.Results: Group PL consisted of 109 and group LL of 107 patients. Median age was 43.93±15.94 years in Group PL and 46.15±14.54 years in Group LL. Male to female ratio, stone burden and localization were similar for both groups. Overall success rate was 89.9% in Group PL and 87.9% in Group LL, respectively (p<0.791). With the aid of additional procedures, success rate was 100% for both groups at the end of the first month. Groups were not different as for operative time, rate of insertion of an ureteral catheter and its removal time. Hospitalization period was apparently somewhat shorter in Group LL (p= 0.00). Conclusion:Pneumatic lithotripsy can be as efficacious as laser lithotripsy and be used safely in the endoscopic management of ureteral stone. In comparison of both methods, we detected no differences as to operative time, success of operation and the time to removal of the catheter, however, hospitalization period was shorter in Group LL.

“…Laser lithotripsy (Mulvaney and Beck 1968, Fair 1978, Watson et al 1987 requires delivery of laser light into the body. For this procedure to be minimally invasive, the light is transmitted through an optical fibre in a catheter which should be as small as possible.…”

“…It was almost seven decades later in 1968 that Mulvaney and Beck [2] developed a ruby laser capable of calculus fragmentation with considerable expenditure of energy, resulting in excessive heat production. The thermal effects on the surrounding tissues precluded its clinical use.…”
