经尿道蓝激光治疗膀胱尿酸结石2例报告

ABSTRACT：ObjectiveTo report the clinical data of two patients with prostatic hyperplasia and bladder uric acid stones，so as to provide reference for clinical practice.MethodsClinical data of two patients successfully undergoing blue laser lithotripsy in Department of Urology，Zhenba County Peoples Hospital were retrospectively analyzed，including clinical manifestations，surgical methods，treatment outcomes and complications.ResultsBoth patients sought medical care due to progressive dysuria or hematuria.B ultrasound and magnetic resonance imaging confirmed bladder calculi and prostatic hyperplasia.One patient also had large blood clots in the bladder cavity.Both patients received transurethral blue laser prostate vaporization + transurethral bladder stone holmium laser lithotripsy.The stone surface was dark yellow，with no obvious pores，fine particles or spike protrusion.Blue laser produced an “ablative” phenomenon similar to vaporization，and then stones became smaller and fragmented.The lithotripsy lasted for 11 min and 8 min，respectively.There were multiple bladder mucosal injuries due to constant drift of stones during operation.Stone composition analysis suggested uric acid stones.After 3 months of follow-up，both patients had smooth postoperative urination，good urine control，and no stone recurrence.ConclusionBlue laser can be applied to crush uric acid stones，and the bladder mucosa should be protected during lithotripsy.
