PURPOSE The aim of the study was to report the experience with renal cell carcinoma (RCC) in children. MATERIALS AND METHODS We conducted a retrospective study on renal adenocarcinoma cases treated in our center between 1993 and 2008. The age limit was established at 15 years. We collected data on personal history, diagnostic age, sex, clinical(More)
OBJECTIVE To evaluate the long-term results of one-stage perineal anastomotic urethroplasty for post-traumatic paediatric urethral strictures. PATIENTS AND METHODS Thirty-five boys who had a perineal anastomotic urethroplasty for post-traumatic bulbous or posterior urethral strictures between 1991 and 2003 were analysed retrospectively. Patients were(More)
OBJECTIVES To assess the prognostic factors that could be used to predict tumour recurrence and progression, and to construct and validate a predictive index. PATIENTS AND METHODS Between June 1991 and December 2000, 533 patients (418 men and 115 women; mean age 55.4 years) underwent complete transurethral resection of histologically confirmed pTa and pT1(More)
PURPOSE To review our experience of tubularized incised plate (TIP) urethroplasty in children with hypospadias defects. METHODS Of 500 children (mean age 6 years) who received a TIP urethroplasty, 439 (87.8%) had primary hypospadias and 61 had one failed previous repair. The hypospadias defects were coronal in 110 (22%), distal penile in 261 (52.2%),(More)
PURPOSE Posterior urethral valves represent the most common obstructive uropathy in children with a broad spectrum of clinical severity. We evaluated prognostic variables affecting the outcome of renal function in such children. MATERIALS AND METHODS Between 1987 and 2004, 120 patients with a mean age of 2 years with posterior urethral valves were treated(More)
OBJECTIVE We report our experience with ureterocalyceal anastomosis in children regarding indications and outcome. MATERIALS AND METHODS A retrospective review was performed of all cases that underwent open ureterocalyceal anastomosis at our center between 2000 and 2006. Records were reviewed for patient age, history, affected side, indication of surgery(More)
OBJECTIVE To evaluate the prognostic role of antenatal diagnosis of posterior urethral valves (PUVs) on ultimate renal function. METHODS Between 1990 and 2010, 315 patients with PUVs were diagnosed and treated at 2 separate tertiary centers. Primary valve ablation was performed in all patients except 18, who underwent initial vesicostomy. Patients were(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 aim of the study was to report the surgical complications that may occur during or after primary ablation of posterior urethral valve (PUV) in a large number of cases treated using different modalities. MATERIALS AND METHODS We retrospectively reviewed a database of 291 patients with PUV treated by primary valve ablation from 2 separate(More)
OBJECTIVE To examine the efficacy and tolerability of tizanidine for the treatment of dysfunctional voiding in children compared with those of doxazosin. METHODS A total of 40 children with dysfunctional voiding were enrolled in a prospective, randomized, 2-parallel group, flexible-dose study. The evaluations were performed in accordance with the(More)
