ABSTRACT = {<b>Introduction: </b>The aim of this study was to determine the 
efficacy and potential complications of double-J ureteric 
stents in the treatment of primary hydronephrosis in 
pediatric patients.<br/>
<b>Materials and methods:</b> A retrospective case-records 
review of 133 patients (45 girls and 88 boys) treated because 
of primary hydronephrosis with double-J ureteric stents, 
in Department of Pediatric Surgery, Split University 
Hospital, between December 1997 and December 2014, 
was performed. Success of treatment, results of follow up 
investigations and complications were recorded. Patients 
were followed up clinically and radiologically for a 
minimum of 2 years following stent insertion.<br/>
<b>Results:</b> In all, 133 endoscopic double-J ureteric stents 
insertions were performed. Of the total number of patients, 
left-sided hydronephrosis was found in 82 patients, rightsided in 38, and bilateral in 13 patients. The median age of 
children was 2 years (range 0-17 years). Mean hospital stay was 2 days (range 1-10 days). In primary hydronephrosis, 
double-J ureteric stenting alone was effective with resolution 
of hydronephrosis in 73% of cases (97/133 insertions). 
Regarding the age of the patients the highest success of 83.5% 
was achieved in age group 0-4 years. Success in groups 5-9 
years; 10-14 years and 15-17 years were 47%; 33.5% and 
0%, respectively. Several complications have been recorded: 
symptomatic infections, migration in the renal pelvis and 
bladder, progression of hydronephrosis, spontaneously 
prolapse of prosthesis, bleeding and perforation of the renal 
pelvis. A significant, decreasing trend in success rates by 
age of participants was observed (p < 0.001).<br/>
<b>Conclusions:</b> Ureteric stenting is minimally invasive 
procedure that provides an alternative to open surgery 
in patients with primary hydronephrosis. Endoscopic 
placement of ureteric double-J stents should be considered 
as a first-line treatment in the management of primary 
hydronephrosis especially in children till 4 years of age, 
with success rate of 83.5% and without the need for 
conventional surgery. In a case of failure we are timeconsuming to definitive surgery.},
