Bladder augmentation is an important tool in the management of children requiring reconstructions for urinary incontinence or preserving of the upper urinary tract in congenital malformations. We reviewed the literature and evaluated the long-term results of enterocystoplasty in the pediatric age group and summarized techniques, experimental options and(More)
A rabbit model was used for the evaluation of a collagen-based biomatrix of small intestinal submucosa (SIS, COOK) in comparison to a biochemically reconstructed biomatrix for bladder tissue regeneration. Rabbits underwent partial cystectomy and cystoplasty with SIS patch graft or with a biochemically defined collagen biomatrix. The grafts of the(More)
Tubular type I collagen biomatrices with and without growth factors (GFs) were constructed and evaluated in a rabbit model for critical urethral defects. Porous tubular biomatrices with an inner diameter of 3  mm were prepared using highly purified collagen fibrils and were crosslinked with or without heparin. Heparinized biomatrices were supplemented with(More)
OBJECTIVE In this study, we evaluated the urological complications and their consequences after renal transplantation in children. MATERIALS AND METHODS A retrospective study was performed concerning urological complications after kidney transplantation in children at the University Medical Center St Radboud Nijmegen from August 1977 until July 1999. The(More)
PURPOSE We evaluated the outcome of postpubertal patients who underwent 1-stage hypospadias repair before onset of puberty with at least 10 years of followup. MATERIALS AND METHODS A total of 2,053 patients underwent surgical repair of hypospadias between January 1981 and May 2004 at our hospital. We evaluated patients who are now at least 18 years old(More)
OBJECTIVE The evaluation of collagen-based biomatrix (SIS COOK((R))) in comparison to a biochemically reconstructed biomatrix for replacement of the urethra in a rabbit model as a preclinical model. MATERIAL AND METHODS Rabbits underwent partial urethra replacement (resection of 0.5 to 1.0 cm segment of the urethra), which was replaced with 1 or 4 layers(More)
