OBJECTIVES To assess the surgical and long-term results of renal transplantation in 25 patients with bladder dysfunction and augmentation cystoplasty. METHODS We retrospectively reviewed the evolution and surgical outcome of 25 renal transplants in 24 recipients with augmentation cystoplasty. The mean patient age at transplantation was 27.6 years. The(More)
PURPOSE We evaluate the incidence of incisional hernia after kidney transplantation, predisposing factors and the results of surgical repair with polypropylene mesh. MATERIALS AND METHODS We reviewed the records of 371 consecutive kidney transplants performed between April 1995 and February 2000. Patients with clinical signs of hernia at the transplant(More)
OBJECTIVES The present study aimed to evaluate the prevalence and associations of renal dysfunction in patients with rheumatoid arthritis (RA). It specifically addressed the hypotheses that renal dysfunction in these patients may associate with the presence of insulin resistance, dyslipidaemia, uric acid levels and/or current levels of systemic(More)
OBJECTIVES CD40L is a costimulatory molecule and an early activation marker of T-lymphocytes. Based on the hypothesis that activated T-cells may play a role in the pathogenesis of psoriatic arthritis (PsA), we evaluated the level of CD40L expression on T-cells from patients with PsA. METHODS We analysed 12 patients with PsA, six patients with rheumatoid(More)
BACKGROUND We reviewed our experience with third, fourth, and fifth renal transplants performed by the extraperitoneal access. METHODS The charts of 21 third and subsequent transplants performed extraperitoneally were reviewed. Surgical aspects, the occurrence of rejection episodes, delayed graft function (DGF), graft and patient survival were evaluated(More)
PURPOSE Transplant nephrectomy has been considered a hazardous procedure throughout transplantation history. Better surgical techniques and clinical treatment of patients have improved the results of this surgery in the last decades. We report the surgical complications of nephrectomy of early and late failed kidneys performed at a referral center. (More)
PURPOSE We examined the development of urological abnormalities in a group of pediatric renal transplant recipients. MATERIALS AND METHODS We reviewed 211 patients younger than 19 years who underwent 226 renal transplants. Three groups of patients were studied-136 children with end stage renal disease due to a nonurological cause (group 1), 56 children(More)
UNLABELLED Biopsy is the gold standard for the diagnosis of conditions affecting the function of renal allografts. Obtaining representative tissue in biopsies is critical but these procedures are associated with up to 9% of complications and 20% of inadequate material. Although ultrasound guidance allows perfect control of depth and location of the graft,(More)
