Summary The purpose of this study was to assess outcomes of urological complications after kidney transplantation operation. Nine‐hundred and sixty‐five patients received a kidney transplant between 2000 and 2006. In total, 58 (6.01%) developed urological complications, including urinary leakage (n = 15, 1.55%), stenosis (n = 29, 3%), vesicoureteral reflux (VUR) (n = 12, 1.2%), calculi (n = 1, 0.1%) and parenchymal fistulae (n = 1, 0.1%). Urinary leakage cases were treated by ureteroneocystostomy (UNS) via a double‐J stent and stenosis cases by UNS. Fenestration was performed in patients developing lymphoceles and unresponsive to percutaneous drainage. VUR treatment was performed by ureteroneocystostomy revision or UNS. Stent usage during ureteric reimplantation was observed to reduce urinary leakage. Surgical complication rates in renal transplantation recipients according to donor type (living versus cadaveric) and the status of stent use (with stent versus without stent) were 5.53% vs. 7.27% (P = 0.064) and 5.24% vs. 20% (P < 0.01) respectively. No recurrence, graft loss or death was seen after these interventions. Comparison of recipients with and without urological complication showed that there was no difference between groups (P > 0.05) with respect to last creatinine level. No graft or patient loss was associated with urological complications. Urological complications that can be surgically corrected should be aggressively treated by experienced surgeons and graft loss avoided.

There is an improvement of endothelial function as assessed by FMD of the brachial artery after RTx in HD patients. This may be attributed to the elimination of uraemic toxins by successful RTx.

Peritoneal ultrafiltration seems to be an efficient and safe procedure and a treatment of choice in elderly patients with RCHF without non-terminal CKD. Peritoneal ultrafiltration improves the quality of life and the effort capacity, and reduces hospitalization rates due to decompensated heart failure and acute renal failure.

This study shows that PD patients without known atherosclerotic disease can also be characterized by endothelial dysfunction and AOPP levels independently predict endothelial function level in PD patients.

Backgrounds: Oxidative stress (OS) and asymmetric dimethylarginine (ADMA) are accepted as nonclassical cardiovascular risk factors in end-stage renal disease patients. To clarify the role of these factors in the atherosclerotic process, we investigated if OS and ADMA are associated with common carotid artery intima media thickness (CIMT) in peritoneal dialysis (PD) patients. Methods: Thirty PD patients without known atherosclerotic disease and classical cardiovascular risk factors as well as age- and gender-matched 30 healthy individuals were included. We measured serum thiobarbituric acid-reactive substances (TBARS), malondialdehyde (MDA), advanced glycation end product (AGE), pentosidine, advanced oxidation protein products (AOPP), ADMA and CIMT in each subjects. Results: TBARS, MDA, AOPP, AGE, pentosidine and ADMA levels were significantly higher in PD patients than in controls (p < 0.001). CIMT in patients was higher than in the control group (0.83 ± 0.09 vs. 0.77 ± 0.06 mm; p < 0.01). CIMT was independently correlated with TBARS (β = 0.33, p < 0.01), MDA (β = 0.27, p < 0.01), AOPP (β = 0.22, p < 0.02), AGE (β = 0.45, p < 0.01), pentosidine (β = 0.56, p < 0.01) and ADMA (β = 0.54, p < 0.01). Conclusions: OS markers and serum ADMA levels independently predict the CIMT level in PD patients.

Objective• To evaluate the outcome of anti-reflux revision surgery in patients diagnosed with at least a grade 3 reflux at voiding cysto-urethrography in patients with recurrent urinary tract infection (UTI) after renal transplantation. Patients and Methods• We identified 60 patients with a diagnosis of recurrent febrile UTI and post-transplantation vesico-ureteric reflux (VUR) who underwent open surgical correction of reflux.• Patient characteristics, including the aetiology of end-stage renal disease, age, time to VUR correction, type of VUR correction, serum creatinine levels, and number of UTIs before and after correction were documented. Results• The median (range) age of the patients was 31.5 (9-65) years. A total of 30 patients underwent uretero-ureterostomy or pyelo-ureterostomy and 30 underwent extravesical or intravesical ureteric reimplantation.• The median (range) creatinine levels before and after correction were 1.5 (0.8-4.5) mg/dL and 1.3 (0.7-4.5) mg/dL (P < 0.05), respectively.• The median (range) number of UTI episodes reported before the correction surgery was 4 (3-12), whereas number of UTI episodes after the surgery was 1 (0-12), the difference being significant (P < 0.05). Conclusions• Open surgical correction of post-transplant VUR is an effective and safe method of decreasing UTI episodes and stopping reflux.• Surgical correction of reflux may prolong the life of the renal graft.
