BACKGROUND Supraglottic airway devices with noninflatable cuff have advantages in omitting the cuff pressure monitoring and reducing potential pharyngolaryngeal complications. Typical devices without cuff inflation available in children are the i-gel and the self-pressurized air-Q intubating laryngeal airway (air-Q SP). To date, there is no comparative(More)
PURPOSE To measure shear wave velocities (SWVs) by acoustic radiation force impulse (ARFI) ultrasound elastography in normal kidneys and in hydronephrotic kidneys in young children and to compare SWVs between the hydronephrosis grades. METHODS This study was approved by an institutional review board, and informed consent was obtained from the parents of(More)
Quantitative measurements of renal echogenicity using a graphic program show close correlation with renal histology in adult patients, but this has neither been applied in pediatric patients nor correlated with glomerular filtration rate (GFR). To determine the direct relationship between echogenicity and GFR, we retrospectively analyzed 91 patients with a(More)
OBJECTIVES To review our initial experience with transvesicoscopic ureteral reimplantation (TVUR) in children with vesicoureteral reflux and to evaluate the learning curve for the feasibility and reproducibility of TVUR. METHODS TVUR was performed in 28 consecutive patients with a mean age of 6.0 years. Cohen's classic technique was reproduced using a(More)
PURPOSE The purpose of this study is to determine detrusor thickness as a prognostic factor in posterior urethral valves. METHODS The medical information of 41 patients diagnosed with posterior urethral valves at our institute was retrospectively reviewed. The serum creatinine level after bladder decompression, results of ultrasonography, and voiding(More)
PURPOSE Bladder outlet obstruction (BOO) causes storage and voiding dysfunction in the lower urinary tract. We investigated the expression of transient receptor potential cation channel subfamily M member 8 (TRPM8) to evaluate the relationship between TRPM8 expression and overactive bladder (OAB) in a rat model of BOO. METHODS Fifty female Sprague-Dawley(More)
OBJECTIVE Previous reports have suggested that the incidence of spina bifida occulta in patients with nocturnal enuresis is higher than in the general population. However, the effect of spina bifida occulta on the response to nocturnal enuresis treatment is controversial. The purpose of this study was to investigate the relationship between spina bifida(More)
OBJECTIVE To investigate the characteristics of primary non-refluxing megaureter with ectopic insertion and its effects on renal function. METHODS Of 118 patients diagnosed with primary non-refluxing megaureter, we retrospectively studied 33 patients who underwent surgical treatment. Depending on the position of ureteral insertion, patients were(More)
PURPOSE Intrarenal reflux (IRR) occurs in 3-10% of cases of total reflux and can lead to renal injury, which may eventually result in renal scarring. In this study, we evaluated the clinical importance of IRR detected by voiding cystourethrography and evaluated the relationship between IRR and renal scarring. MATERIALS AND METHODS From January 2002 to May(More)
Urinary nerve-growth-factor (NGF) level reflected the severity of urgency in patients with lower urinary tract symptoms (LUTS) and pain in patients with Bladder pain syndrome/interstitial cystitis (BPS/IC). The aim of this study was to investigate the levels of biomarkers, nerve growth factor (NGF), and prostaglandin E2 (PGE2) among disease groups sharing(More)
