Despite being a biologically well tolerated material, lyophilized human dura mater is not good for urethral strictures because of the high number of relapses and possibility of malignancy.

A right-renal angiomyolipoma with tumour thrombus into the inferior vena cava was incidentally detected. This is the ninth published case of its type and the second incidental case. Presence of a thrombus does not imply invasive disease, but the tumour then is often bigger than 6 cm and radical surgery is mandatory.
