Efficacy of external physical vibration lithecbole combined with potassium sodium hydrogen citrate in treatment of hydronephrosis-free patients with lower calyceal small calculi / 中华全科医师杂志

ABSTRACT

A prospective randomized controlled study was conducted in 120 patients with hydronephrosis-free lower calyceal calculi in Jiangshan People′s Hospital from June 2020 to August 2021. Patients were divided into drug group, vibration group and combination group by random number table method with 40 cases in each group. The drug group was treated with potassium hydrogen citrate sodium, the vibration group was treated with external physical vibration lithotripsy (EPVL), and the combination group was treated with EPVL combined with potassium hydrogen citrate sodium. The renal stone discharge rate and complications were observed and compared among three groups 1, 2 and 4 weeks after treatment. The overall discharge rate in 120 patients was 39.2%(47/120). The discharge rate of vibration group and combination group were higher than that of drug group ( P<0.05). There were no significant differences in stone discharge rate at 1 and 2 weeks after treatment between vibration and combination group ( P=0.63 and 0.14), while the calculi discharge rate at 4 weeks after treatment in combination group was higher than that in vibration group ( P=0.03).The overall incidence of complications in 120 patients was 12.5% (15/120), that of drug group, vibration group and combination group was 7.5%(3/40), 15.0%(6/40), and 15.0% (6/40), respectively ( P<0.05). No serious complication occurred, and all patients recovered well after treatment. The results suggest that EPVL can promote the discharge of small calyceal calculi in hydronephrosis-free patients, and potassium hydrogen citrate sodium can further facilities the discharge of renal stone.
