Background: Tacrolimus is an approved first-line immunosuppressive agent for kidney transplantations. Part of interindividual and interethnic differences in the response of patients to tacrolimus is attributed to polymorphisms at CYP3A5 metabolic enzyme. gene expression status is associated with tacrolimus dose requirement in renal transplant recipients.

Objective: The aim of this study was to compare the efficacy of antimicrobial [silver sulfadiazine (SSD)]-coated ureteral stents with non-coated stents in the prevention of stent-related bacteriuria.

Materials And Methods: A randomized controlled trial was conducted between September 2014 and September 2016 after approval from the local ethics committee. Inclusion criteria were adults who underwent unilateral double-J ureteral stent placement after ureteroscopic lithotripsy.

Objective: To evaluate the protective effects of selenium with vitamins A, C and E (selenium ACE, i.e. antioxidants), verapamil (calcium channel blocker), and losartan (angiotensin receptor blocker) against extracorporeal shockwave lithotripsy (ESWL)-induced renal injury.

Stone culture has been frequently investigated following percutaneous nephrolithotomy (PNL) in the last decade. We aimed to crucially define the clinical role of stone culture in modifying the treatment plan in patients with postoperative sepsis. Between June 2012 and April 2013, a total of 79 consecutive PNL procedures were included.

Objective: The present study was designed to determine the possible impact of hepatitis C virus (HCV) infection on the expression of telomerase (TERT), retinoblastoma (RB1), E2F3, TP53, CDKN1A (p21) and fibroblast growth factor receptor- 3 (FGFR3) genes in patients with bladder cancer (BC).

Materials And Methods: 100 patients with bladder cancer (15 female and 85 male) were divided into 2 groups; Group I: 50 HCV negative subjects (age range 36-79), and Group II: 50 HCV positive subjects (age range 42-80). Expressions of the telomerase, retinoblastoma (Rb), E2F3, TP53 and FGFR3 genes were tested by immunohistochemistry and real time PCR in tumour tissues and healthy bladder tissues.

Background: Nail changes are common complications of end-stage renal disease, and reports of nail changes in kidney transplant recipients (KTR) are rare. Few reports have documented a higher prevalence of onychomycosis in KTR compared with controls, while others found no significant differences. In this study, we investigated the prevalence and nature of nail changes in a large series of KTR.

Objective: To asses the efficacy and safety of bidirectional synchronous twin-pulse extracorporeal shock wave lithotripsy (ESWL) compared with standard ESWL.

Patients And Methods: Between March 2003 and December 2006, 240 patients with a radio-opaque single renal stone of View Article and Find Full Text PDF

Objective: To assess prospectively the incidence with time of asymptomatic bacteriuria in patients with orthotopic ileal neobladders, and the possible effect on neobladder function.

Patients And Methods: In all, 47 patients (mean age 52.7 years, sd 8.

Background: The potential benefit of pre-transplant treatment of chronic hepatitis C on long-term evolution after renal transplantation is not clear.

Methods: Fifty successive renal transplant candidates had their sera positive for HCV RNA and a biopsy-proven chronic hepatitis. Out of these, 18 patients received a standard course of interferon-alpha2b (IFN; 3 MU three times weekly after hemodialysis sessions for 6 months).

The aims of this study were to investigate the prevalence of hepatitis C virus (HCV) genotypes and serotypes in anti-HCV-positive hemodialysis patients and determine the concordance between genotyping and serotyping methods. Sixty-two hemodialysis patients were included in this study. HCV RNA was determined using polymerase chain reaction assay and genotypes using a line probe assay.

Background/aim: Transforming growth factor-beta1 (TGF-beta 1) is involved in the pathogenesis of chronic allograft nephropathy after kidney transplantation. The aim of the study was to evaluate the effect of the angiotensin receptor blocker losartan on TGF-beta 1 plasma levels and proteinuria in hypertensive transplant recipients.

Methods: A total of 162 transplant recipients were included in the study.
