Emphysematous pyelonephritis is a life-threatening infection that usually requires open surgical drainage. We report a case of emphysematous pyelonephritis treated successfully with percutaneous drainage.

Percutaneous nephrostomy insertion has, in recent times, become a subspecialised skill performed by an interventional trained Radiologist. However, this creates access issues, particularly in remote and regional medical centres. In this article, we describe a simple and effective method for computed tomography (CT)-guided percutaneous nephrostomy insertion, utilising the CT interventional skills of the general radiologist.

This study suggests that in cases of GI bleeding emergency angiography is likely to be more rewarding when it follows a Tc‐99m RBC scintigram which demonstrates active GI bleeding. The added advantages of angiography include more accurate anatomical localization and the possibility of therapeutic radiological intervention. These advantages should be considered in the individual patient before deciding to proceed directly to surgical intervention based on positive scintigraphy alone. Where the scintigram does not demonstrate active bleeding there is no need to perform emergency angiography, however, elective angiography may demonstrate a possible cause for bleeding. Chronic GI bleeding remains a diagnostic dilemma, however, elective angiography has a small but definite role in the diagnostic workup of these cases because of its ability to demonstrate a possible causative lesion.

Renal oncocytomas are uncommon benign tumours that have recently been recognized as a unique pathological entity. These lesions may attain considerable size; however, most present as an asymptomatic incidental finding. Although usually solitary, these tumours are occasionally multicentric or bilateral at presentation. Retrospective studies suggest that oncocytoma may account for up to 5% of turnours previously classified as well‐differentiated renal cell carcinoma. At present, conservative management is hampered by difficulty in establishing a confident pre‐operative or intra‐operative diagnosis. A case of bilateral asymptomatic renal oncocytoma is presented, and the implications of this lesion for the management of renal tumours is discussed.
