Abstract:
Objective To explore the efficacy of transurethral nephroscopic pneumatic lithotripsy combined with ultrasound lithotripsy for bladder calculus.MethodsBy using transurethral F20.8 nephroscope and EMS LithoCaster,we performed transurethral nephroscopic pneumatic lithotripsy and ultrasound lithotripsy on 69 patients with bladder calculus(63 men and 6 women)between October 2005 and May 2008.The diameter of the calculi was ranged from 1.5 to 6.0 cm.Among the patients,42 had one stone in the bladder,while 27 had multiple calculi.Fifty-five patients were complicated with BPH,14 had neurogenic bladder,and 4 showed bladder diverticulum with stones in situ.Pneumatic frequency was set at 8-12 Hz,and ultrasonic energy was 50%-60%.For the patients with BPH electrovaporization ablation was plused.ResultsAmong the 69 patients,68 were cured in one session.The mean operation time was 25 minutes(15 to 40 minutes).One patient was converted to open surgery because of rupture of the bladder during the procedure.No patient had urethral stricture,infection,or massive hemorrhage during the operation.Follow-up was available in 68 patients for 6 to 10 months(mean,9 months).During the period,no recurrent calculi was found by ultrasonography and X-ray.ConclusionTransurethral nephroscopic pneumatic lithotripsy combined with ultrasound lithotripsy is effective for bladder calculus.
