- Purpose: We evaluated parameters associated with testicular salvage in boys with testicular torsion.
Materials and Methods: During 2009-2014, 19 boys younger than 18 years old underwent emergency surgery for testicular torsion in our hospital. Age, chief complaint, laterality of the torsion, physical appearance, ultrasonographic results, duration between the onset of symptoms and hospital visit, duration between the onset of symptoms and start of surgery, intraoperative appearance, surgical method (orchiopexy or orchiectomy), and any postoperative complications were analyzed retrospectively. Cases were categorized according to salvageable testes (n=14) or unsalvageable testes (n=5) groups based on testes viability.
Results: The mean age was not significantly different between the two groups. All patients were diagnosed using color Doppler ultrasonography of the scrotum. Six (42.9%) boys in the salvageable testes group and all five in the unsalvageable testes group were transferred from other clinics or hospitals (p=0.026). The mean duration between the onset of symptoms and hospital visit was 925 minutes in the salvageable testes group and 3,488 minutes in the unsalvageable testes group (p=0.042), and the mean duration between the onset of symptoms and start of surgery was 1,131 minutes in the salvageable testes group and 3,777 minutes in the unsalvageable testes group (p=0.042).
Conclusions: There was a high possibility that orchiectomy was required if surgery was delayed. However, even when a boy is admitted to the hospital more than 24 hours after the onset of symptoms, the testis can still be viable provided the surgery is performed as quickly as possible.

- Purpose
The purpose of this study is to evaluate the incidence and risk factors of febrile urinary tract infection (UTI) after endoscopic therapy for vesicoureteral reflux (VUR).
Materials and Methods: Analysis of the clinical data of 88 children (128 refluxing renal units; male 60%, female 40%) in a single institution during March 2011-June 2013 including age, gender, sorts and volume of agent for injection, preoperative VUR grade, recurrent UTI, bladder dysfunction, nephropathy, postoperative VUR, urinalysis, and urine culture results was performed retrospectively. All patients were followed for three to 62 months (average 25 months).
Results: After the first injection, the complete resolutions rate of VUR (by ureter) was 72.7%, consisting of grade I 4 (90%), grade II 11 (84.6%), grade III 29 (76.3%), grade IV 33 (66%), and grade V 93 (72.7%) ureters. Preoperative UTI and febrile UTI were present in 81 (92.0%) and 49 patients (55.7%), respectively. Preoperative recurrent UTI and febrile UTI were observed in 53 (60.2%) and 30 patients (34.1%), respectively. Postoperative UTI and febrile UTI occurred in eight (9.1%) and in five patients (5.7%), respectively. In multivariate analysis, only preoperative recurrent UTI (odds ratio [OR], 0.17; p=0.04) and bladder trabeculation (OR, 0.104; p=0.038) were independent variables after endoscopic therapy.
Conclusions: Our data support that the successful endoscopic correction of VUR is associated with a low incidence of febrile UTI. The highest risk factor for post injection UTI is preoperative recurrent UTI and bladder dysfunction. Therefore, patients with preoperative recurrent UTI and bladder dysfunction require careful observation after endoscopic therapy for VUR.
