Objective To explore an effective treatment for benign prostatic hyperplasia complicated with bladder stones.Methods Swiss LithoClast Master and transurethral resection of the prostate(TURP)were performed on 33 patients with benign prostatic hyperplasia complicated with bladder stones.Results The operations were completed successfully in all the cases with a mean lithoclasty time of 35 min(15-65 min),and mean TURP time of 85 min(50-110 min).No blood transfusion,TUR syndrome,bladder perforation,or residual stone occurred during and after the operations.Urethral catheter was withdrawn 5 days postoperation,none of the patients had urinary incontinence or dysuria.The diagnosis of benign prostatic hyperplasia was confirmed by pathology examination.Three months after the operations,IPSS decreased from 23.4?5.2 to 7.4?1.2(t=3.732,P=0.000);maximum urinary flow rate increased from(5.4?1.5)ml/s to(18.6?3.2)ml/s(t=2.491,P=0.015);and QOL decreased from 3.9?1.2 to 2.0?0.7(t=2.454,P=0.014).Conclusions EMS LithoClast Master combined with TURP is an effective treatment for benign prostatic hyperplasia complicated with bladder stones.
