[CLINICAL EXPERIENCE OF TRANSURETHRAL INJECTION USING DEXTRANOMER-HYALURONIC ACID COPOLYMER (Deflux) FOR CASES OF SECONDARY VESICOURETERAL REFLUX AFTER URETEROCYSTONEOSTOMY].

(Objective) We reviewed the clinical efficacy of transurethral Deflux injection therapy (Deflux injection therapy) in patients with secondary vesicoureteral reflux (VUR) after ureterocystoneostomy. (Methods) We retrospectively evaluated data for Deflux injection therapy in 4 patients after ureterocystoneostomy with secondary VUR due to lower urinary tract dysfunction treated at this hospital from 2010 through 2018. The indications for surgery were febrile urinary tract infection or new renal scarring, and the outcomes of treatment with Deflux injection therapy were evaluated.

Ureterosciatic Hernia Treated with Laparoscopic Intraperitonization of the Ureter.

Ureterosciatic hernia (USH) is a rare benign disease. We report a case of USH treated with laparoscopic intraperitonization of the ureter. A 70-year-old woman was admitted to our hospital with right abdominal pain lasting for 2 months.

Long-term outcomes of pediatric kidney transplantation: A single-center experience over the past 34 years in Japan.

Objectives: To evaluate long-term outcomes and risk factors for graft loss in pediatric kidney transplantation over a 30-year period.

Methods: We retrospectively assessed 400 consecutive kidney transplants carried out in 377 children during 1975-2009. Patients were stratified according to the immunosuppressive regimen (era 1: methylprednisolone and azathioprine; era 2: calcineurin inhibitor-based therapy, including methylprednisolone and azathioprine or mizoribine; era 3: basiliximab induction therapy, including calcineurin inhibitors, methylprednisolone and mycophenolate mofetil).

Compound heterozygous splice site variants in the SCLT1 gene highlight an additional candidate locus for Senior-Løken syndrome.

Senior Løken syndrome (SLS) is a heterogeneous disorder characterized by severe retinal degenerations and juvenile-onset nephronophthisis. Genetic variants in ten different genes have been reported as the causes of SLS. Clinical evaluation of a patient with SLS and her unaffected parents revealed that the patient had infantile-onset retinal dystrophy and juvenile-onset nephronophthisis.

[ACUTE SCROTUM IN THE PEDIATRIC EMERGENCY ROOM: A SINGLE CENTER RETROSPECTIVE STUDY].

(Objective) The objective of this study was to survey cases of acute scrotum examined at the pediatric emergency room (ER). (Subjects and methods) All patients examined for acute scrotum at the emergency outpatient unit between March 2010 and March 2014 were designated subjects of the study. Medical records were used to retrospectively investigate the final diagnoses including testicular torsion (TT), torsion of the testicular appendage, epididymitis, orchitis, incarcerated inguinal hernia, idiopathic scrotal edema, Schönlein-Henoch purpura, hydrocele, external trauma, as well as those with no confirmed diagnosis.

Color Doppler Ultrasound Evaluation of Ureteral Jet Angle to Detect Vesicoureteral Reflux in Children.

Purpose: Vesicoureteral reflux is the most common urinary tract abnormality in children. Although voiding cystourethrography is the gold standard for diagnosing reflux, this approach is invasive. We evaluated color Doppler ultrasound measurement of ureteral jet angle as a noninvasive screening tool for detecting reflux.

[Clinical characteristics and outcomes of congenital midureteral stricture detected by fetal ultrasonography].

Objectives: Congenital midureteral stricture (CMS), which develops from obstructive lesion between pyeloureteral junction and ureterovesical junction, is relatively rare and its clinical condition and therapeutic strategy have not yet been established. We analyzed the clinical characteristics and surgical outcomes of CMS.

Patients And Methods: From November 2006 to December 2012, out of 137 patients presented with congenital hydrohephrosis, we identified 4 pediatric patients diagnosed with CMS at our institutions.
