Clinical application of physical vibration lithecbole in upper urinary calculi after extracorporeal shock-wave lithotripsy / 中华泌尿外科杂志

ABSTRACT

Objective To observe the curative effect of external physical vibration lithecbole (EPVL) therapy after extracorporeal shock-wave lithotripsy (ESWL) in upper urinary calculi.Methods A total of 133 patients of upper urinary calculi with randomly divided into 2 groups after ESWL therapy during the period of 2012 October to 2013 February.The EPVL group (66 cases) used the physical vibration lithecbole treatment,and the natural lithecbole group (67 cases) used the method by drinking water,adding exercise and other natural lithecbole method.Of the EPVL group,6 of the stones were located in the upper or middle calyx,13 in renal pelvis,16 in lower renal calyx and 31 in ureter,the stone diameter was 10-15 mm.Of the natural lithecbole group,8 of the stones were located in the upper or middle calyx,17 in renal pelvis,15 in lower renal calyx and 27 in ureter,the stone diameter was 10-15 mm.The clinical data of the curative effect,side-effect,and complications were collected and analyzed systematically.Results In the EPVL group,the average times of lithagogue treatment was 2.6 times,51 patients (77％) expelled stones on the day of lithecbole,and the stone free rate in a week was 79％ (52/66).Especially,81％ (13/16) of the lower renal calyx expelled stones on the day of lithecbole,and the stone free rate in a week was 88％ (14/16).Whereas,30 patients (45％) in the natural lithecbole group expelled stones on the day of ESWL,and the stone free rate in a week was 49％ (33/67) ; the lower renal calyx stone expulsion rate on the day of ESWL was 33％ (5/15),and the stone free rate in a week was 40％ (6/15).The curative effects were significantly different between the 2 groups (P＜ 0.05).There were no serious complications in both groups.Conclusions EPVL machine can significantly promote the stone expulsion after ESWL.Compared with traditional methods,EPVL therapy has a better curative effect,especially on lower renal calyx stones.EPVL is a safe and noninvasive treatment.
