Introduction: Peritoneal dialysis is the treatment of choice for end-stage renal disease. Peritoneal dialysis related peritonitis is of great importance for patient and technical survival. The aim of our study was to evaluate the accuracy and the correlation between the three methods (complete blood count, urinalysis device, urine dipstick test) and with the reference manual method (Thoma Cell Counter Chamber).

Introduction: As intensive care units (ICU) have improved, presence of multiple-organ dysfunctions in majority of patients with acute renal failure (ARF) has become clearer. To facilitate multi-organ support, continuous renal replacement therapy (CRRT) techniques have been developed. This study is the one that reports the experience on children including newborns receiving CRRT monitored in ICU.

Objective: This study describes a single-center experience on percutaneously performed partial omentectomy procedure in pediatric peritoneal dialysis (PD) patients who showed early catheter dysfunction and required catheter replacement due to catheter flow obstruction.

Materials And Methods: We performed a retrospective review of clinical outcomes from pediatric PD patients who underwent percutaneous catheter replacement by pediatric nephrologists between November 1995 and December 2012. Partial omentectomy was performed in those patients in whom omental or adhesion trapping to the catheter tip was seen.

Background: Although short-term renal allograft survival in children has improved over the years, long-term graft outcomes remain unclear. In this study we report the characteristics and other variables that impact long-term kidney graft survival in children.

Material And Methods: Records of 61 pediatric kidney transplant recipients (mean age: 14±3 years) performed at our institution between 1995 and 2011 were evaluated.

Objective: Malnutrition is closely linked to chronic kidney disease (CKD) in adult patients with poor outcome. But data on pediatric patients is inadequate. The aim of this study was to describe the prevalence of growth failure and malnutrition in pediatric CKD patients and explore the relationship of these parameters to each other and to other clinical parameters.

Objective: Our aim in the present study was to identify outcomes in children with special needs or social disadvantage, or both, receiving chronic peritoneal dialysis (CPD) treatment in a pediatric dialysis unit.

Methods: Among 110 children started on CPD in our unit during the period between November 1995 and November 2008, we identified 13 patients (8 girls, 5 boys) with major physical, mental, or psychosocial problems. Age at CPD initiation in the group with disability ranged from 4.

Peritonitis and catheter exit- site infections (ESI) are important causes of hospitalization and catheter loss in patients undergoing chronic peritoneal dialysis (CPD). The frequency of infection can be reduced by scrupulous exit- site care with or without topical antiseptics. There are no studies showing any benefit in the use of povidone-iodine or normal saline for care of exit- sites in long- term CPD patients.

Objective: To evaluate the frequency of urinary tract infections (UTIs) and degree of renal parenchymal damage as well as the parameters of growth, development and nutritional status in antenatal hydronephrosis cases with vesicoureteral reflux (VUR).

Methods: Infants, whose antenatal ultrasonography (US) showed a fetal renal pelvic diameter of 5 mm or greater were investigated. Of the 277 infants with antenatal HN, 36 [56 renal units (RUs)] were diagnosed with VUR.

Cardiovascular disease is a leading cause of long-term morbidity and mortality among children with chronic kidney disease (CKD). At which stage of CKD these appear in children is unknown. This study aimed to determine the prevalence of cardiovascular disease in pediatric CKD patients and to explore the relationship of these changes and treatment methods.

The medical records of children discharged with a diagnosis of Henoch-Schönlein purpura (HSP) between January 1996 and March 2006 were analyzed retrospectively. The patient population consisted of 430 children (225 boys, mean age: 7.9 +/- 2.

Henoch-Schonlein Vasculitis (HSV) is systemic small vessel vasculitis involving the skin, kidney, joints, and gastrointestinal tract. The proportion of patients reported to have renal involvement varies between 20% and 80%. Rapidly progressive glomerulonephritis (RPGN)is rare syndrome in children, characterized by clinical features of glomerulonephritis (GN) and rapid loss of renal function.

The measurement of aortic stiffness (As) [aortic strain (S), pressure strain elastic modulus (Ep) and pressure strain normalized by diastolic pressure (Ep*)] is suggested as an excellent marker of subclinical arterial sclerosis. We aimed to investigate the presence of As and to determine the relationship between As and some risk factors in children with chronic renal failure (CRF). Twenty-six pre-dialysis (PreD) [female/male (F/M) 7/19] patients and 23 chronic peritoneal dialysis (CPD) (F/M 13/10) patients were assessed.

Background: Chronic peritoneal dialysis (CPD) in children is an important modality of renal replacement therapy. The ideal method for inserting CPD catheters remains still controversial. Minimal invasive techniques are becoming more popular.

Allergic dermatitis around the catheter exit site, caused by topical antiseptics such as povidone iodine and chlorhexidine gluconate, is an uncommon complication in patients on chronic peritoneal dialysis (CPD). As yet, published reports concerning this rare non catheter-related complication are few. The frequency of this type of dermatitis is not known, because reports of isolated cases constitute the only source of information.
