To introduce flexible ureterorenoscopy with holmium laser lithotripsy in the management of symptomatic caliceal diverticular calculi.
The records of 26 patients who underwent flexible ureterorenoscopy and lithotripsy with holmium laser to manage symptomatic caliceal diverticular calculi from January 2012 to June 2016 were retrospectively reviewed.
Flexible ureterorenoscopy lithotripsy was successfully placed in all 26 patients. Twenty-two cases accepted lithotripsy at the same time, and the success rate was 84.6%. The stone-free rate was 76.9%.The mean operative time was 48 ± 16 minutes. The mean hospital stay was 4.8 ± 1.6 days. There was no evidence of stone regrowth or recurrence at a mean follow-up of 11.5 months.
Flexible ureterorenoscopy with holmium laser lithotripsy is safe and effective, and it can be offered as a first line therapy for symptomatic caliceal diverticular calculi.
