BACKGROUND: Bacterial infections significantly affect graft loss and mortality after kidney transplantation (KT). We reviewed the frequencies, risk factors, and sources of bacterial infections after KT and their impact on graft and patient survivals. METHODS: The data of 154 kidney recipients who underwent transplantation from 2010 to 2015 were explored. Donor, recipient, and surgical parameters were collected, and source, type, and frequency of infectious complications, number of infective episodes, multidrug-resistant (MDR) bacteria, and the bacterial spectrum were established...

: Mayor urological complications, fistulae and stenosis, mainly affect the vesicoureteral anastomosis and present in the early post-transplant period. The systematic use of ureteral catheters keeps selecbeing controversial with many groups using them only selectively depending on the existence of pretransplant or intraoperative risk factors. METHODS: We performed a bibliographic review through automatized search in the Medline bibliographic database, as the main bibliographic source, and also in Clinical Key...

Background: Ureteral stenosis is part of the common complications of renal graft reported in 3% to 7% of cases. Multiple treatments have been introduced regarding length and position of the stenosis. Metal stents for urologic purpose were created in 1998. Double percutaneous antegrade and transurethral retrograde access to a ureteral stenosis to a long-term metal stent procedure has been rarely described. Case Presentation: Here, we present a case of a ureteral stricture in a double ipsilateral kidney graft with a common ureter...

Cellular and antibody-mediated rejection processes and also interstitial fibrosis/tubular atrophy (IFTA) lead to allograft dysfunction and loss. The search for accurate, specific and non-invasive diagnostic tools is still ongoing and essential for successful treatment of renal transplanted patients. Molecular markers in blood cells and serum may serve as diagnostic tools but studies with high patient numbers and differential groups are rare. We validated the potential value of several markers on mRNA level in blood cells and serum protein level in 166 samples from kidney transplanted patients under standard immunosuppressive therapy (steroids±mycophenolic acid±calcineurin inhibitor) with stable graft function, urinary tract infection (UTI), IFTA, antibody-mediated rejection (ABMR), and T-cell-mediated rejection (TCMR) applying RT-PCR and ELISA...

OBJECTIVES: Chronic kidney disease caused by lower urinary tract abnormalities is a significant complication in pediatric care. Although there are conflicting reports about clinical outcomes in the past, favorable outcomes have been reported in recent years. Despite this, many centers still refrain from performing renal transplant in these patients. Here, we compared clinical outcomes of renal transplant recipients with and without lower urinary tract abnormalities. MATERIALS AND METHODS: Our study included 71 renal transplant recipients who were divided into 3 groups: 17 patients with abnormal lower urinary tracts having vesicoureteral reflux (group 1), 7 patients with abnormal lower urinary tracts having bladder dysfunction (group 2), and 47 patients with anatomically and functionally normal lower urinary tracts (group 3)...

Infectious complications remain a major cause of morbidity and mortality among transplant recipients. Urinary tract infection (UTI) is the most common infectious complication in kidney transplant recipients with a reported incidence from 25% to 75%, varies widely likely due to differences in definition, diagnostic criteria, study design, and length of observation. We sought reviews the incidence and importance of urinary tract infection on graft survival, the microbiology with special emphasis on multidrug resistant microorganisms, the therapeutic management of UTI and the prophylaxis of recurrent UTI among solid organ transplant recipients, highlighting the need for prospective clinical trials to unify the clinical management in this population...

Over 26 years, we found 46 infectious episodes in 350 kidney transplant recipients. Fifteen were urinary tract infections, recurrent in 4 patients. There were 8 cytomegalovirus infections, three of them fatal when intravenous (IV) ganciclovir was not available. Seven patients had a reactivation of tuberculosis (TB) in the pleura, cervical spine, lumbar spine, knee, ankle, skin and peritoneum, respectively, and were all resolved satisfactorily with conventional anti-TB therapy. Three patients transplanted before routine prophylaxis with the use of acyclovir developed an extensive herpes zoster infection in the 1st 6 months after transplantation, which was resolved with the use of oral acyclovir, and 1 had a disseminated herpes simplex infection resolved with the use of IV acyclovir...

The indication of antimicrobial treatment for asymptomatic bacteriuria (AB) after kidney transplantation (KT) remains controversial. Between January 2011 and December 2013 112 KT recipients that developed ≥1 episode of AB beyond the second month post-transplantation were included in this open-label trial. Participants were randomized (1:1 ratio) to the treatment group (systematic antimicrobial therapy for all episodes of AB occurring up to 24 months post-transplantation [53 patients]) or control group (no antimicrobial therapy [59 patients])...
