Introduction
The first description of encrusted pyelitis (EP) was reported by Morales et al. in 1992 [1]. EP is an infectious disease defined as the presence of encrustations in the wall of the pelvicaliceal system, sometimes extending to the ureter, associated with inflammation of the surrounding tissues [2,3]. EP may be associated with encrusted cystitis, in which the pathophysiology is identical. The development of EP requires predisposing factors including the presence of urea splitting bacteria responsible for alkaline urine, a preceding urological procedure or a pre-existing mucosal lesion. The presence of a stent in the collecting system increases the risk of EP. Associated immunosuppression is an important cofactor, present in most of the patients [25]. Early urological complications after renal transplantation that require a secondary procedure were shown to be a predisposing factor to the development of EP within the
Pathophysiology: the role of Corynebacterium group D2
Diagnosis: value of imaging and laboratory techniques
Conservative rather than surgical management
Prognosis and outcome: risks in kidney transplant recipients
