Endoscopic laser lithotripsy: safe, effective therapy for ureteral calculi

Area of Science:

• Urology
• Endourology
• Laser Medicine

Background:

• Ureteral calculi pose a significant clinical challenge.
• Traditional treatments for ureteral stones can involve invasive procedures.
• Laser lithotripsy has emerged as a key therapeutic modality.

Purpose of the Study:

• To evaluate the efficacy and safety of laser lithotripsy for ureteral calculi.
• To assess the impact of a miniaturized ureteroscopic system on treatment outcomes.
• To determine the cost-effectiveness of endoscopic laser lithotripsy in a community hospital.

Main Methods:

• Retrospective review of 204 patients undergoing laser lithotripsy for ureteral calculi over 11 months.
• Utilized a pulse-dye laser with a miniaturized ureteroscopic system.
• Assessed stone fragmentation, need for ureteral dilation, pain, hospitalization, and complications.

Main Results:

• Satisfactory stone fragmentation achieved in 198 of 204 procedures (97%).
• Miniaturized ureteroscope allowed access without dilation in 165 of 204 patients (81%).
• Lack of dilation correlated with decreased pain and shorter hospital stays; low complication rate observed.

Conclusions:

• Endoscopic laser lithotripsy with a miniaturized ureteroscope is highly effective for ureteral calculi.
• Avoiding ureteral dilation improves patient outcomes and reduces healthcare resource utilization.
• This technique represents a safe, reliable, and cost-effective treatment option for ureteral stones.
