Renal Papillary Necrosis (RPN) is idefined as Ischemic necrobiosis of the papilla in the medulla of the kidneys. Variety of etiological factors are recognized which cause papillary necrosis, such as analgesic nephropathy, diabetes mellitus, urinary obstruction and sickle cell haemoglobinopathy. The early diagnosis of RPN is important to improve prognosis and reduce morbidity. Radiological Imaging offers early diagnosis and can guide prompt treatment of papillary necrosis and can minimize a decline in renal function. Here we report three cases of RPN with typical imaging findings. One of them was diabetic and hypertensive female with recurrent Urinary tract Infections and other was a male with no known co-morbidity. Both of them were diagnosed to have renal papillary necrosis on CT scan and were managed operatively and conservatively, respectively. Third case was a healthy female being investigated to be renal donor for her son. Here RPN was an incidental finding and was treated conservatively. Thus CT scan could detect it pre-operatively and complications due to transplantation of a kidney with papillary necrosis were avoided. So, we want to emphasize the importance of Radiology, particularly CT scanning in detection of RPN and to guide early and prompt treatment.
