Introduction: Pediatric pyeloplasty with double J (DJ) stent drainage requires manipulation of the uretero-vesical junction (UVJ) and a second anesthetic for removal. Externalized uretero-pyelostomy (EUP) stents avoid these issues. We report outcomes of laparoscopic and open pyeloplasty with EUP compared to DJ stents in children. Methods: We retrospectively reviewed 76 consecutive children who underwent pyeloplasty for ureteropelvic junction (UPJ) obstruction over a 1-year period by 5 pediatric urologists at a single institution. The exclusion criteria included patients with concomitant urological procedures, other urinary drainage strategies, "stentless" pyeloplasty or patients without follow-up data. Based on surgeon preference, 24 patients had a EUP stent and 38 had a DJ stent placed. Results: The mean follow-up was 23.8 ± 10.9 months and 21.1 ± 11.1 months for the EUP and DJ stent groups, respectively (p = 0.32). The mean age was 40 ± 54 months and 80 ± 78 months for the EUP and DJ groups, respectively (p = 0.04). The EUP group had a greater proportion of open pyeloplasties (n = 17, 71%) versus the DJ group (n = 16, 42%; p = 0.04). There were no statistically significant differences in operative time, length of stay, and overall complication rate between groups. Complications were divided by timing of complication (intraoperative, before and after 3 months) and according to the Clavien Classification system. There were no statistically significant differences between these subgroups. The limitations of this study include small sample size, potential selection bias, and heterogeneity between both study groups. Conclusions: Pyeloplasty using EUP stents does not incur prolonged operative time, longer length of stay or higher complication rate when compared to DJ stents. Within the limitations of this study, EUP stents may be a safe alternative to DJ stents.

Urinary tract infections (UTIs) represent a common bacterial cause of febrile illness in children. Of children presenting with a febrile UTI, 25-40% are found to have vesicoureteral reflux (VUR). Historically, the concern regarding VUR was that it could lead to recurrent pyelonephritis, renal scarring, hypertension, and chronic kidney disease. As a result, many children underwent invasive surgical procedures to correct VUR. We now know that many cases of VUR are low-grade and have a high rate of spontaneous resolution. The roles of surveillance, antibiotic prophylaxis, endoscopic injection, and ureteral reimplantation surgery also continue to evolve. In turn, these factors have influenced the investigation of febrile UTIs.Voiding cystourethrography (VCUG) is the radiographic test of choice to diagnose VUR. Due to its invasive nature and questionable benefit in many cases, the American Academy of Pediatrics (AAP) no longer recommends VCUG routinely after an initial febrile UTI. Nevertheless, these guidelines pre-date the landmark Randomized Intervention of Children with Vesicoureteral Reflux (RIVUR) trial and there continues to be controversy regarding the diagnosis and management of VUR. This paper discusses the current literature regarding radiographic testing in children with febrile UTIs and presents a practical risk-based approach for deciding when to obtain a VCUG.
