Vesicoureteral reflux (VUR) is reported in 30%-50% of children affected by urinary tract infection (UTI). We aimed to investigate the frequency of VUR in children presenting with UTI and the changes in its prevalence from birth up to 18 years. This research was an observational retrospective study in the nephrology clinic of an academic tertiary hospital during 2003-2016.

Case Presentation: Herein, we describe a case with a diagnosis of an intrathoracic kidney associated with the ectopic spleen and diaphragmatic hernia diagnosed during imaging studies for urinary tract infections (UTIs). This study reports an 11-month-old male case with a history of CDH and several episodes of UTIs.
Introduction: Association of constipation with incomplete bladder emptying, functional bladder outlet un-coordination, urinary tract infection (UTI), and upper urinary tract dilatation has been reported. We designed a study to determine the impact of chronic functional constipation on kidney and bladder ultrasound parameters, the results of the uroflowmetry test, and its association with UTI.
Methods: The study group consisted of 24 cases and 48 controls, who were children between 5 to 18 years-old, from June 2017 to June 2018.

However, the mechanisms underpinning the cytotoxic effects of this compound are not entirely elucidated. Cisplatin produces anticancer effects primarily via activation of the DNA damage response, followed by inducing BCL-2 family dependent mitochondrial apoptosis.

Despite notable advances in SCLC genomics, new therapies remain elusive, largely due to a lack of druggable targets. We used a high-throughput drug screen to identify a venetoclax-sensitive SCLC subpopulation and validated the findings with multiple patient-derived xenografts of SCLC.

Crossed renal ectopia is a rare urinary system anomaly which mostly is asymptomatic and is diagnosed incidentally. Urinary obstruction, infection, and neoplasia of the urinary system and nephrolithiasis are main complications of this anomaly. A 6-year-old boy admitted to the hospital with colicky abdominal pain and nausea.

Objectives: We aimed to assess the efficacy of high doses of oral folate and vitamin B12 in reducing plasma Hcy levels after a 12-week treatment.
Patients And Methods: Thirty-two dialysis patients aged 10-324 months screened for hyperhomocysteinuria.
Introduction: Carnitine deficiency is commonly seen in dialysis patients. This study assessed the association dialysis and pediatric patients' characteristics with plasma carnitines levels.
Materials And Methods: Plasma carnitine concentrations were measured by tandem mass spectrometry in 46 children on hemodialysis or peritoneal dialysis.
Introduction: Nocturnal enuresis (enuresis) is one of the most common developmental problems of childhood, which has often a familial basis, causes mental and psychological damage to the child and disrupts family solace.
Objectives: In this study, we compared therapeutic effects of combination therapy of desmopressin plus oxybutynin with desmopressin plus tolterodine, in the treatment of children with primary nocturnal enuresis.
Patients And Methods: The present study is a clinical trial study, where 59 patients with primary nocturnal enuresis in the age range of 5 to 14 years old were selected from the visitors of nephrology clinic of Dr.
Introduction: There is limited data about urolithiasis in young infants. We reviewed clinical, imaging, and biochemical data of urolithiasis in the first 2 months of life.
Materials And Methods: In an 11-year period, 77 of the 1172 children diagnosed with urolithiasis (6.
Background: Although 98% of children attain daytime bladder control by three years of age, urinary incontinence is regarded physiological up to the fifth year of life.
Objectives: This study aimed to assess whether lower urinary tract urological abnormalities and abnormal urodynamic findings are infrequent in children with physiological urinary incontinence in contrast to those with non-monosymptomatic nocturnal enuresis (NMNE).
Patients And Methods: During a three-year period (2007-2009), 66 neurologically normal children including 51 children (34 girls, 17 boys) older than five years of age with NMNE and intermittent daytime incontinence, and 15 children with physiological urinary incontinence (eight girls and seven boys) aged four to five years of age without any known urological abnormalities were enrolled in the study.

Bacterial infections are common in patients with nephrotic syndrome, including peritonitis, sepsis, meningitis, urinary tract infection, and cellulitis. An 8-year-old boy presented with colicky abdominal pain, vomiting, swollen and painful erythematous lesions around the umbilicus and in anterior surface of left thigh (cellulitis), mild generalized edema, and ascites. The microorganism isolated from peritoneal fluid and blood cultures was Pneumococcus.

Objectives: This study was conducted to measure and compare the radiation dose in spot films with photofluorography voiding cystourethrography (VCUG) in children.
Patients And Methods: 111 [222 Kidney Urinary Unit (KUU)] pediatric patients, aged 1 month to 5 years, with symptomatic urinary tract infection were enrolled in the study.

Background: The prevalence of vesicoureteral reflux (VUR) is higher in enuretic children than in non-enuretic children. Recent studies have reported VUR in 6-23% of children with enuresis.
Objectives: To clarify the association of nocturnal enuresis with vesicoureteral reflux (VUR) and to identify children who are at risk for VUR.

Background: Nocturnal enuresis is divided into monosymptomatic nocturnal enuresis (MNE) and non-monosymptomatic nocturnal enuresis (NMNE). This study reviews clinical and ultrasonography (US) findings in enuretic children, and compares the organic and functional pathologies of the lower urinary tract (LUT) in children with MNE to those who have NMNE.
Methods: We enrolled 111 neurologically normal children with chief complaints of enuresis in this study.
Reduced nocturnal bladder capacity has been suggested in the pathogenesis of nocturnal enuresis. This study was conducted to define frequency of bladder dysfunction in enuretic children and determine parameters which might predict bladder dysfunction. 60 children were enrolled.

Materials And Methods: Nineteen pediatric calculus formers, 12 girls and 7 boys, aged 15 days to 60 months, with idiopathic hypercalciuria received high-dose hydrochlorothiazide (1 mg/kg/d to 2 mg/kg/d) and citric acid-potassium citrate (1 mEq/kg/d) and were evaluated in a 2-year period. Avoiding high-salt diets was recommended throughout the study and increasing fluid intake was encouraged.
Introduction: We aimed to identify metabolic and anatomical abnormalities present in children with urinary calculi.
Materials And Methods: Metabolic evaluation was done in 142 pediatric calculus formers. Evaluation included serum biochemistry; measurement of daily excretion of urinary calcium, uric acid, oxalate, citrate, and magnesium (in older children); and measurement of calcium, uric acid, oxalate, and creatinine in random urine samples in nontoilet-trained patients.
This study was conducted to determine the prognostic value of some clinical, laboratory, histopathologic and therapeutic factors in 62 children with focal segmental glomerulosclerosis. There were no significant differences between the factors studied, except for severe interstitial fibrosis, which was more frequent in patients with chronic kidney disease (P=0.03).

Even though this defect is common among siblings and parents of index patients (27-40%), the mode of inheritance is not well defined. Parents and siblings (three female and two male) of a 13-year-old girl with end-stage renal failure (ESRF) due to reflux nephropathy were screened for VUR although they had not presented episodes of urinary tract infection.
