Pulsed dye laser lithotripsy is a recently developed technique for the management of urinary calculi. This article reports the results of treatment of a cohort of patients managed with this technology. Post-treatment bed stay was generally less than 48 h, narcotic analgesia was not regularly required, and no significant post-treatment complications were encountered. This treatment appeared to complement an existing extracorporeal shockwave lithotripsy (ESWL) service at St Vincent's Hospital and may offer a financial advantage in the treatment of patients with urinary calculi.
