    Abstract:
    PURPOSE: Pulsed dye laser lithotripsy has shown to be an effective and safe procedure for treatment of ureteral calculi. We report our experience. MATERIAL AND METHODS: A total of 1000 patients were treated with pulsed dye laser between January 1990 and February 1996. In 450 patients the procedure was performed under general or regional anaesthesia; the remaining 550 patients were treated with the aid of a mild sedation. RESULTS: In the mild sedation group a total of 417 out of 550 patients (75.8%) had their calculi completely cleared (85.6% of effectiveness in women with pelvic lithiasis). Different facts caused the treatment to fail in the remaining patients: severe pain, vagal reaction and technical difficulties. In the anesthesia group the procedure was effective in 346 cases (76.9%). Laser failed to clear calculi in 104 patients in this group due to technical impossibility and persistence of ureteral fragments. Additional treatment options in order to achieve resolution of the calculi were: ESWL, both ESWL and laser, Dormia basket, Zeiss stent, three-prong grasping forceps, ureterolithotomy and nephrectomy. Morbidity was higher in the group treated under anesthesia, being haematuria the most frequent adverse effect. CONCLUSIONS: We believe that ureteroscopy and laser lithotripsy is an effective, safe and low morbidity procedure for the treatment of ureteral calculi in women with distal calculi. It is often suitable to perform it with mild sedation with the subsequent benefit for both the patient and health care system regarding to cost-effectiveness balance.
