Renal ailments

A 55-year-old man presented with right renal colic and with a history of intermittent lower back disorders. At the time of admission, clinical examination showed lower back pain on contact. Renal ultrasound objectified heterogeneous mass at the lower pole of the right kidney with dilation of lower calyx groups. Abdominal CT scan confirmed the presence of right inferior renal polar lesion characterized by mixed density, associated with significant hydronephrosis eroding the renal parenchyma upstream of a voluminous pyelic coralliform lithiasis. The patient underwent nephrectomy with anatomopathological examination revealing chronic inflammation of the renal parenchyma characterized by macrophages associated with monocytes and lymphocytes with spongy cells and fibrosis.
