Flexible Ureterorenoscopy Management of Calyceal Diverticular Calculi.

OBJECTIVE: To introduce flexible ureterorenoscopy with holmium laser lithotripsy in the management of symptomatic caliceal diverticular calculi.

MATERIALS AND METHODS: 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.

RESULT: 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.

CONCLUSION: 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.
