INTRODUCTION The management of urolithiasis in children differs from adults because of anatomic and metabolic abnormalities. At present, various minimally invasive and invasive treatment strategies have been recommended to treat urinary tract Stones, including shock wave lithotripsy (SWL), standard percutaneous nephrolithotomy (PNL), mini-PNL, retrograde(More)
OBJECTIVE To examine the relationship between the mean platelet volume (MPV) and varicocele to clarify the etiopathogenesis of varicocele. METHODS MPV levels were measured in 60 varicocele subjects (group I) and 57 healthy controls (group II) from 2009-2010. Ages were similar between the 2 groups. The diagnosis of varicocele was based on the findings from(More)
The aim of this study was to compare the success and complication rates of a 4.5 F ureteroscope with a 7.5 F ureteroscope in the treatment of urolithiasis in preschool-age children. We retrospectively reviewed 69 ureteroscopy (URS) procedures in a pediatric population (40 boys, 29 girls). We divided the patients into two groups according to the type of(More)
This study aimed to investigate the effectiveness and reliability of micro-percutaneous nephrolithotomy (micro-PNL) for the management of kidney stones in pediatric patients. This retrospective study included 24 infants that underwent micro-PNL for renal stones between March 2012 and April 2015. The inclusion criteria included: age younger than 2 years,(More)
OBJECTIVE To compare the effectiveness and safety of pneumatic and holmium:YAG laser lithotripters in the treatment of pediatric ureterolithiasis. PATIENTS AND METHODS Medical records of patients treated using pneumatic (PL) (n = 29) or laser (LL) (n = 35) lithotripter between 2009 and 2011 were retrospectively analysed. The patients were evaluated with(More)
BACKGROUND/PURPOSE To report the first technical feasibility and safety of microperc in the treatment of pediatric nephrolithiasis. METHODS A multicenter prospective trial was initiated and microperc was performed in 19 children from four different centers. In all cases, 4.85-Fr all-seeing needle was used to access the collecting system under direct(More)
The aim of this study was to investigate the efficacy and safety of ureteroscopy (URS) in pregnant patients compared with non-pregnant patients. We reviewed the cases of 41 pregnant and 62 non-pregnant women who developed ureteral stones and were treated with URS in our center between April 2005 and September 2011. A semi-rigid 9.5 F ureteroscope was used.(More)
AIM Varicocele is characterized by abnormal tortuosity and dilatation of the veins of the pampiniform plexus within the spermatic cord and is one of the causes related to male infertility. This study aimed to investigate the correlation between varicocele and somatometric parameters. We also aimed to determine prevalence and treatment ratio of this disorder(More)
To investigate the effect of carvacrol (CAR) on methotrexate (MTX)-induced testis damage in rats. Twenty-four male rats were equally divided into three groups: group I control treatment; group II MTX-treated; group III MTX + CAR-treated. A single dose of CAR was administered intraperitoneally to group III on the first day of the experiment and a single dose(More)
OBJECTIVE The aim of this study was to determine the frequency of anatomical variations of the colon associated with the kidney. MATERIAL AND METHODS A retrospective analysis was performed on 1000 consecutive abdominal computed tomography (CT) scans performed between July 2010 and September 2011. A line parallel to the horizontal plane was drawn through(More)
