“…Also, this figure is close to that reported in adults [12,13]. In addition, the location of most cases of SS in our study was the distal ureter (74.1 %) followed by the proximal ureter (18.5 %), and the incidence was fairly typical to that reported by Onal et al [14] with an incidence of SS formation of 77 and 19 % in the pelvic and lumbar ureter, respectively.…”

“…Lucio et al reported that there was a trend toward more occurrences of SS after SWL for larger stone area >200 mm 2 [13]. In Onal study, the incidence of SS formation was 1.9 % for stones < 1 cm 2 , 15.4 % for stones 1-2 cm 2 and 19.5 % for stones >2 cm [14]. In our study, a direct correlation was found between stone length and subsequent SS development.…”

“…However, in pediatric population only one study evaluated the predictive factors of SS and showed that the stone burden was the only statistically significant factor predicting the formation of SS on logistic regression analysis [14]. That study suffered from some limitations; first it included only those who presented with radiopaque stones; thus, multivariate analysis is specific for predicting the formation of SS after SWL in radiopaque stones.…”

“…After comparing follow-up findings, the stone expulsion time was shortened. Similarly, in Onal et al [15] study, steinstrasse developed in 7.6% of patients who had SWL treatments and a statistically significant factor was stone burden. In most patients (91.8%), authors had not placed JJ catheters before treatment.…”

Purpose: We aimed to evaluate the effects of preoperative urinary catheterization in nephrolithiasis treatment with extracorporeal shock wave lithotripsy (SWL). Methods: Patients admitted to the Department of Pediatric Surgery for renal stones between June 2012 and June 2014 were evaluated retrospectively. Patients were divided into 2 groups based on JJ stent placements. Group 1 did not receive JJ stents, while group 2 did. The recorded demographic data for each group included age, gender, stone size, location, sessions, and complications. The Elmed Complit ESWL system was used with 11-13 kV, and 1,000-1,200 shots in patients 2-4 years of age, and 11-14 kV, and 1,000-1,500 shots for patients over 4 years. Results: In group 1, 18 sessions of SWL were performed on 8 female and 2 male children with a mean age of 4.5 (range 2-12) years and stone diameter of 9 (range 7-15) mm. The locations of the renal stones were in the upper pole in 1 patient, 7 in the lower pole, and 2 in the pelvis renalis. Postoperatively, 1 patient had hematuria, 2 had dysuria, and one had a stone in the external urethral meatus. Eighty percent of patients were stone free; there were no fragmentations in 2 patients, and 1 patient discontinued treatment. In group 2, 15 SWL sessions were performed on 5 female and 5 male children aged 4 (range 3-5) and the stone diameter was 9 (range 7-16) mm. The locations of the renal stones were in the upper pole in 6 patients, in the lower pole in 3 patients, and in the ureteropelvic junction in one patient. JJ stents were placed in all patients preoperatively. Postoperatively, 3 patients had hematuria and one had dysuria. At the end of the study, all of the patients were stone free. Statistically, there were no differences in age, gender, stone size, location, and the number of sessions. Conclusions: Our results indicate that SWL without preoperative ureteral stenting is an effective and safe procedure that can be carried out in the pediatric population. Preoperative JJ stenting is unnecessary in patients, especially in those with smaller stone diameters.
