RESUMEN
The impact of vesicoureteral reflux (VUR) on renal allograft outcomes is debatable, with small cohort studies reporting controversial results. The objective of this retrospective study was to evaluate long-term clinical effects of early VUR in a large cohort of kidney transplant patients. Posttransplantation voiding cystourethrography was used to evaluate 646 consecutive kidney transplant recipients before discharge. The study endpoints included VUR grade, death-censored graft or patient survival, renal function, proteinuria and occurrence of urinary tract infections (UTIs). Of the 646 recipients, 263 (40.7%) were diagnosed with VUR. VUR grade II was most common (19.8%), followed by grades III (10.2%), I (7.9%) and IV (2.8%). VUR was less common in transplantations performed by experienced compared to inexperienced surgeons (36% vs. 48%; p = 0.004). VUR did not affect death-censored graft or patient survival and was not associated with proteinuria or occurrence of UTIs. Patients with VUR had a lower eGFR at 1 year after transplantation than did patients without VUR (60 vs. 52 mL/min/1.73 m(2) ; p = 0.02), although this difference was not observed at 3 and 5 years after transplantation. We conclude that early VUR, a common finding among renal transplant patients, may not have a meaningful impact on long-term transplant outcomes.

In this case report we have described a patient suffering from sclerosing cholangitis, diabetes mellitus type I, and consequent end-stage renal disease who was successfully treated with simultaneous pancreas and kidney transplantation 9 years after orthotopic liver transplantation.

BACKGROUND: Strictures and concrements are the most common biliary complications following liver transplantation. Endoscopic treatment might not lead to a definitive cure in all patients, especially in strictures involving the biliary bifurcation. The aim of this study was to determine the efficacy and the long-term outcome of hepaticojejunostomy (HJS) for post-transplant biliary tract obstruction. MATERIAL AND METHODS: Thirty-seven patients were retrospectively studied for resolving of cholestasis and the incidence of recurring biliary obstruction. RESULTS: Surgery was performed because of anastomotic strictures in 11, ischemic strictures at the donor common bile duct in seven, strictures involving the bile duct bifurcation in 10, hepatolithiasis without strictures in one and biliary cast formation diagnosed by endoscopic retrograde cholangiography or T-tube cholangiography in eight patients. Cholestasis instantly improved in 82% of the patients. After a long-term follow-up of median 33 months (range 3-149), 28 of the patients (76%) required no further intervention for recurring biliary obstruction following HJS. Anastomotic strictures were observed in six (16%), recurring biliary concrements in two patients (5%). CONCLUSION: HJS did prevent recurrent biliary obstruction in the majority of the patients. We therefore recommend early HJS for complicated post-transplant biliary tract obstruction not treatable by a limited number of endoscopic interventions.
