Among 322 cases of primary malignant renal tumours reviewed between 1969 and 1991, six were renal sarcoma (1.85%). They all presented earlier symptomatology which was not different from other renal tumours, and nephrectomy was performed in all cases, 5 of which died before 14 months. The histopathological diagnose showed two liposarcoma, two carcinosarcomas, all the others being fibrosarcomas.
The results obtained after treating 13 patients with low flow priapism diagnosed by cavernous gasometry, penile ecodoppler and cavernosography are explained. Seven cases of priapism (53%) developed following intracavernous injection of vasoactive drugs and had a good response to aspiration lavage and alpha-agonist medication. None of the cases needed shunt technique to achieve detumescence and all showed good evolution with regard to the erectile function. Six cases of priapism (47%) were idiopathic and they all needed some type of venous by-pass. Later, only one had normal erections.
