OBJECTIVES To compare the results of retroperitoneal laparoscopic with open partial nephroureterectomy. PATIENTS AND METHODS Laparoscopic retroperitoneal partial nephroureterectomy was undertaken in 15 children (13 upper and two lower poles; median age at the time of surgery 61 months, range 5-212). A three-trocar retroperitoneal approach was used. The(More)
CONTEXT Over the last two decades, minimally invasive treatment options for ureteropelvic junction obstruction (UPJO) have been developed and popularized. OBJECTIVE To critically analyze the current status of laparoscopic and robotic repair of UPJO. EVIDENCE ACQUISITION A systematic literature review was performed in November 2012 using PubMed.

PURPOSE Nephrectomy may be indicated in children with end stage renal disease before transplantation. We studied the feasibility and results of nephrectomy performed via a retroperitoneal laparoscopic approach in these high risk children. MATERIALS AND METHODS We performed 12 nephrectomies in 9 children with end stage renal disease and a mean age of 7(More)
PURPOSE Laparoscopic procedures are still not widely performed by pediatric urologists due to operative time and costs as well as the lack of indications and, thus, the lack of sufficient surgeon experience. We report our experience with the retroperitoneal approach using special inexpensive methods for various indications in children. MATERIALS AND(More)
BACKGROUND Pentoxifylline (PTX) has been shown to reduce hepatic injury after normothermic ischemia and reperfusion (I-R) in rat liver. AIM The aim of this study was to evaluate the effects of PTX on liver expression of tumor necrosis factor alpha (TNFalpha) mRNA following normothermic liver I-R. MATERIALS AND METHODS A segmental normothermic ischemia(More)
PURPOSE We describe the functional outcome following tubularized incised plate repair of hypospadias in toilet trained children after an intermediate followup. MATERIALS AND METHODS Children were included in this study only if they were toilet trained and had flow rate data not less than 6 months after primary tubularized incised plate hypospadias repair(More)
PURPOSE We systematically reviewed the literature published during the last 20 years on the treatment of primary proximal hypospadias associated with severe ventral curvature. MATERIALS AND METHODS We reviewed studies published between 1990 and December 2009, searching for "hypospadias" in MEDLINE/PubMed, EMBASE, Web of Science and the Cochrane Library.(More)
PURPOSE To assess the impact of prenatal diagnosis and evaluation on the outcome of posterior urethral valves we studied all cases of valves detected prenatally, including cases of pregnancy termination due to posterior urethral valves. MATERIALS AND METHODS Between 1989 and 1996, 30 neonates with prenatally detected posterior urethral valves were treated(More)
PURPOSE Management of posterior urethral valves is significantly modified by the prenatal diagnosis. Our aim was to assess long-term outcome of children with prenatally detected posterior urethral valves treated at our institution by primary valve ablation without routine urinary drainage or diversion. MATERIALS AND METHODS A total of 79 cases of(More)
PURPOSE The indications for laparoscopy in pediatric urology are expanding and yet the advantages over open surgery remain unclear. We compared the results of retroperitoneal laparoscopic vs open pyeloplasty for pyeloureteral junction obstruction in children. MATERIALS AND METHODS A total of 22 children with a mean age of 88 months (range 25 to 192)(More)
