BACKGROUND/AIMS: Children with a solitary functioning kidney have a risk of renal injury caused by hyperfiltration. Timely intervention with renin-angiotensin inhibitors may be beneficial. We examined whether trajectory of estimated glomerular filtration rate (eGFR) would predict renal injury, defined as microalbuminuria/proteinuria, hypertension, and/or a decline in eGFR. METHODS: Seventeen patients (male 7, female 10) with multicystic dysplastic kidney (MCDK; median age 13 years, range 6-19 years) followed in our clinic were examined retrospectively...

The case of a 16-year-old male patient with left renal artery stenosis due to fibromuscular dysplasia (FMD) and an atrophic kidney due to a right multicystic dysplastic kidney (MCDK) who presented with refractory hypertension is reported. On continuous Doppler imaging, the peak systolic velocity (PSV) at the stenotic site of the left renal artery was 404 cm/s. The FMD formed a "string-of-beads" appearance on computed tomographic angiography (CTA) and renal artery angiography. Percutaneous transluminal renal angioplasty (PTRA) with a balloon catheter was performed, after which the left renal artery returned to near normal, and his blood pressure decreased to within the normal range...

BACKGROUND: Minimally invasive surgery is considered to be the gold standard treatment for nephrectomy in children. In recent decades it has been proposed that laparoendoscopic single-site (LESS) surgery is a feasible alternative to perform laparoscopic nephrectomies. OBJECTIVE: The aim of our study was to compare the safety and efficacy of LESS against conventional laparoscopic (CL) nephrectomy. STUDY DESIGN: From March 2010 to November 2012 charts of pediatric patients who underwent laparoscopic nephrectomy at our tertiary center were revised...

Multicystic Dysplastic Kidney (MCDK) is one of the most common renal conditions seen in paediatric population. The natural history typically involves involution and many of the patients with unilateral disease may actually never become symptomatic. The initial evaluation is usually done on Ultrasonography (USG) while cross-sectional imaging and nuclear scan are reserved for diagnostic dilemmas. Management is conservative and surgery is done for selected patients with symptomatic cysts or suspicion of neoplasm...

AIMS: To evaluate the usefulness of the cyst-to-kidney volume ratio determined by ultrasonography (US) in unilateral multicystic dysplastic kidney (MCDK) in children. MATERIAL AND METHODS: Our study group included 21 children (average age: 431 days) with unilateral MCDK and 22 children (average age: 440 days) with unilateral grade IV hydronephrosis due to ureteropelvic junction obstruction as the control group. All the children underwent transabdominal US. In children with MCDK, we calculated cyst-to-kidney volume ratios (volume of the largest cyst/volume of the MCDK) and in the control group the volume ratios of the renal pelvis and the largest calyx (volume of the pelvis or largest calyx/volume of the ipsilateral hydronephrotic kidney)...
