RENAL ALLOGRAFT rupture (RAR) is a rare but very serious complication of renal transplantation, requiring emergency surgery. The most common cause is acute allograft rejection, but other causes such as renal vein thrombosis (RVT), acute tubular necrosis (ATN), renal biopsy, and lymphatic obstruction have been reported. We reviewed our experience with the aim of identifying RAR predisposing cond...

Vascular torsion is a rare renal transplant complication which requires prompt diagnosis and surgery to salvage allograft function. We report here a case of renal allograft torsion with interesting imaging findings on unenhanced CT and color Doppler ultrasound. A 60-year-old woman with a history of pancreas and kidney transplant presented to the emergency room with nausea, vomiting, abdominal p...

 Abstract  Background: Despite the long-standing association of macrophage migration inhibitory  factor (MIF) with delayed-type hypersensitivity response, the potential role  of MIF in chronic allograft nephropathy is unknown. The association between upregulation of MIF expression, macrophage and T cell infiltration and the severity of  chronic allograft nephropathy suggests that MIF may be an ...

CONTEXT Several observational studies have investigated the significance of hypertension in renal allograft failure; however, these studies have been complicated by the lack of adjustment for baseline renal function, leaving the role of elevated blood pressure in allograft failure unclear. OBJECTIVE To examine the relationship between blood pressure adjusted for renal function and survival af...

background: primary infection with bk virus (bkv) is occurred during childhood and usually asymptomatic, but after initial infection, bkv may persist lifelong in the kidney and genitourinary tract. reactivation may occur in individuals with compromised immunity such as renal transplant recipients. due to the role of bkv in bk virus-associated nephropathy (bkvan) and potentially renal allograft ...

The first successful transplantation of a human kidney was performed more than 50 years ago by Murray and colleagues in 1954 between identical twins. The success of this transplantation was due to the fact that no significant rejection occurs between genetically identical twins and therefore immunosuppression was not necessary in this particular case (Merrill et al., 1956). However, solid-organ...

BACKGROUND Renal transplantation is a therapy for end-stage renal disease. During the study of recipients' survival after renal transplantation, there are some events as intermediate events that not only affect the recipients' survival but also events which are affected by various factors. The aim of this study was to handle these intermediate events in order to identify factors that affect rec...

BK virus (BKV) is a polyomavirus with seroprevalence in adults, ranging from 60 to 100%. It is considered as usual cause of renal dysfunction after the allograft renal transplantation nephropathy. Potent immunosuppressive therapy in kidney transplantation can lower the rate of acute rejection. Therefore, untreated BKV infections lead to kidney allograft dysfunction or loss. In order to estimate...

Background: Warts are common in renal allograft recipients (RAR) with reported incidence of 24% to 100%. These patients also demonstrate an accelerated malignant transformation of warts. Although in immunocompetent patients, the histology of common warts is quite predictable, this is not so in RAR. Objective: The purpose of this study was to evaluate the histopathologic findings of warty lesion...

BACKGROUND Page kidney phenomenon is caused by strong renal parenchymal compression and leads to renal hypoperfusion and microvascular ischemia, resulting in renal dysfunction and hypertension. Although the development of Page kidney phenomenon in allograft is rare, most of its cases are induced by allograft biopsy or trauma. We observed a case of Page kidney phenomenon that was induced by unus...
