Call for Scientific Cooperation

#11 Acute renal failure due to urolithiasis (November 2017)

Dear friends and colleagues, we have recently met 10 patients coming to Emergency with acute renal failure that was due to urolithiasis (ureteral stone in single kidney, bilateral ureteral stones, unilateral ureteral stone in borderline renal function, etc). We presented our series in Gdansk at ESUR 2017 and are now preparing a publication. If you have cases and are willing to partecipate please write me at: derchi(at)

#10 Obstructive acute renal failure due to stone disease (June 2017)

Dear Friends,

I have recently met a few patients with obstructive acute renal failure that was due to stone disease: synchronous, bilateral ureteral stones, ureteral stones in single kidneys (either anatomical or functional), renal pelvis stones on one side and ureteral stones on the other, patients with chronic renal failure from bilateral chronic disease who develop acute renal insufficiency from unilateral ureteral stone.

There are quite a few on this topic in the radiological literature and I think a valuable paper can result from collection of such cases.

Thanks for your help,
Lorenzo Derchi

#9 Two separate nodules within the same testis (October 2016)

Dear Friends,

We have recently collected four cases of patients with two separate nodules within the same testis which proved to be of different histologic nature at pathology (three cases had nodules which were tumours of different histology; the remaining case had one nodule which was seminoma while the second was a benign hyaline focal lesion).
If you have similar cases (imaging pictures as well as pathologic proof of the nature of each of the lesions), please contact me derchi(at)

Thanks for your help and ciao,
Lorenzo Derchi

Call #3 Fibrous proliferation of the renal transplant (Dec. 2012)

We have recently met two cases of large fibrous proliferation involving the hilum and pedicle of renal transplants. The patterns were initially suggestive of a lymphoproliferative disorder, but the follow-up show very slow growth while pathology confirmed benignity with massive fibrous proliferation.

If you observed similar cases, please write me: m.claudon(at)

Call #1 Bladder pheochromocytoma (Dec. 2012)

I have recently met a patient with a bladder pheochromocytoma. There are only case reports or small series on this rare conditions, and this new feature of the ESUR website can help to gather many and prepare a meaningful publication.

If you have cases, please write me at: marie-france.bellin(at)
