Introduction & Objective : The purpose of this study is to examine the tolerance and to compare the results of flexible ureteroscopy treatment for the management of renal lithiasis in different age groups of patients


Methods :

A prospective study of 326 patients who underwent ureterorenoscopy with Holium Yag laser for renal lithiasis, performed by a single urologist between September 2014 and March 2017. Patients were classified into 2 groups according to their age. Group 1, ureteroscopy performed at children under 14 years. In the second group, this was done in patients whose ages exceeded 18 years. There were 33 children and 293 adult patients. The study was performed in Per Protocol and the statistical significance was retained when the P


Results : The average age of the patients was between 6.8 years old and 46.8 years old. The average size of the stones was 17.4mm in G1 and 18.1mm in G2. The average density of the calculus was 1002.1UH vs 1092.7UH, in G1 vs G2 respectively. The success rate was respectively 66.6% vs 67.2% in G1 vs G2. The causes of failure were the same in both groups, they were the size of the calculus (OR = 0.5, IC = 0.01- 0.02, p = 0.01, G1 vs IC = 3.4 - 6.5, p <0.004, G2 and the lower calyx seat (OR = 0.56, IC = 0.25-0.19, p = 0.01, G1 vs OR =, IC = 1.4-4.7, p = 0.1; G2) .A multivariate study after logistic regression showed that only the size of the calculus had a significant influence p <0.01. No major complications have been observed. Complications were rare G1: 1% vs G2: 1.7%, p <0.01. The average length of hospital stay was equivalent in both groups. 


Conclusions :

The ureterorenoscopy for the treatment of kidney stones in children is safe, is effective, and has technical similarities with adults. We did not find any difference between the success rates or the complication rates in both groups. The results are equivalent with a low percentage of re-treating the patients.
