[Diagnostic and therapeutic problems posed by renal or para-renal masses of cystic appearances].

The authors report some forty cases of renal masses, cystic in appearance and having raised a certain number of diagnostic or therapeutic problems. These masses included 7 cystic carcinomas, 3 benign tumors of cystic appearance and 28 cysts including 2 infected and 2 hydatid cysts. No paraclinical investigation is infallible in confirming the nature of the mass in doubtful cases, and pre-operative diagnosis is more easily obtained by investigation including the majority of standard imaging methods often completed by puncture.

[Vascular anomalies of the kidney. Apropos of 3 cases].

Two cases of rare vascular lesions of kidney are reported: a patient with a renal angioma and one with an aneurysm acquired after an oster type endocarditis. Both lesions were detected after severe hemorrhage and nephrectomy was performed in each case. Exact diagnosis was dependent on histopathologic findings.

[Study and treatment of erection disorders. Value of intracavernous injections].

A multidisciplinary study of 57 patients with erection disorders included in addition to standard examinations: clinical, hormonal, vascular using Doppler and nervous with determination of latency time of bulbocavernous reflex, evaluation of effects of intracavernous papaverine injections completed by a manometric study of cavernous body filing by perfusion. A clear positive result of the papaverine test is considered to reflect integrity of vascularization of corpus cavernosum structure, and renders value less the continuation of vascular investigations. The appearance of an almost normal but delayed erection requiring high-dose papaverine administration is interpreted as being due to insufficiency of arterial origin without anomaly of venous return.

[Acute epididymitis].

A series of 86 cases of acute epididymitis observed over a period of 3 years is analyzed and findings reported. Testicular lesions were frequent and 35% of these cases involved a purulent testicular pocket. The epididymal lesion was usually of a total nature (77% of cases), only the tail of the epididymis being involved in 17%.

[The vena cava in surgery of renal cancer in the adult].

In a series of 171 radical nephrectomies performed by the authors, 10 patients presented vena cava extension (5.8%). The extension was infrahepatic (stage C) in 6 cases, retrohepatic (stage B) in 1 case and involved the right auricle (stage A) in 2 cases, while the upper limit of the thrombus could not be defined in the remaining case.
