Application of ESWL and F-URS in pediatric nephrolithiasis patients with different body mass

ObjectiveTo investigate the application value of extracorporeal shock wave lithotripsy(ESWL) and flexible ureteroscope(F-URS) lithotripsy in pediatric nephrolithiasis patients with different body mass.

MethodsA total of 41 cases with single pediatric nephrolithiasis were included according to stone size body mass index(BMI) and personal intention.According to BMI, the patients were divided into overweight group(BMI ≥24.0 kg/m², n=20) and non-overweight group(BMI < 24.0 kg/m², n=21).The patients in the two groups were further divided into two subgroups including ESWL group(treated with ESWL) and F-URS group(treated with F-URS combined with holmium laser lithotripsy) according to the treatment method.The common postoperative complications(transient hematuria and postoperative fever), the success rate of one-time lithotripsy and the placement of double-J catheter after operation were compared between subgroups with different treatment method in overweight group and non-overweight group, respectively.

ResultsIn the non-overweight group, the incidence of transient hematuria and postoperative fever, and the number of patients with double-J catheter in the ESWL group were lower than those in the F-URS group(P < 0.05), and there was no significant difference in the success rate of one-time lithotripsy between the two groups(P>0.05).In the overweight group, the success rate of one-time lithotripsy in the F-URS group was higher than that in the ESWL group(P < 0.05), and there was no significant difference in the incidence of transient hematuria and postoperative fever, and the number of patients with double-J catheter between the two groups(P>0.05).

ConclusionsIn non-overweight patient with pediatric nephrolithiasis, ESWL and F-URS have similar therapeutic effects, which can be selected according to the patient's condition or hospital preference.In overweight patient with pediatric nephrolithiasis, the treatment effect of ESWL decreases, while F-URS has a stable lithotripsy effect and is more suitable for overweight patient.
