Background: Phimosis is a rare cause of obstructive uropathy and renal failure. This report presents a case of a 22-year-old man with phimosis, resulting in such complications. Case report: The patient with incidentally revealed elevated serum creatinine level was subjected to ultrasonography, voiding cystourethrography and static fluid MR urography (sMRU), combined with conventional T1- and T2-weighted images. The urinary tract dilatation and the bladder diverticula were diagnosed with the use of imaging modalities. Two months after circumcision the degree of hydroureteronephrosis as well as creatinine level decreased. Conclusions: The obstructive uropathy involving the upper urinary tract and resulting in renal failure may develop on the basis of chronic phimosis. Completing of standard imaging techniques with MR urography significantly improved the possibility of the urinary tract evaluation in the presented case.
