[Should adrenalectomy be performed systematically as part of radical nephrectomy for renal cancer? Review of 119 cases]. / La surrénalectomie doit-elle être systématique lors de la néphrectomie élargie pour cancer du rein? Revue de 119 dossiers.

Systematic histological examination of 119 operative specimens of radical nephrectomies performed for renal cell carcinoma revealed adrenal invasion in 6 cases (5.04%). Preoperative computed tomography visualised the adrenal lesions with a sensitivity of 100%. Adrenal involvement was due to either contiguous invasion (3 cases) or metastatic spread (3 cases). Other visceral or lymph node metastases were detected in every case. The mean survival of patients with an adrenal lesion was 16.5 months. These data and those reported in the literature suggest the value of systematic adrenalectomy as part of radical nephrectomy.

[Functional analysis of micturition and continence after a Hautmann type enterocystoplasty (27 patients)]. / Analyse fonctionnelle de la miction et de la continence après entérocystoplastie de type Hautmann (27 patients).

Twenty seven patients treated by Hautmann enterocystoplasty completed a detailed questionnaire concerning the quality of their micturition and continence. The mean capacity of the neobladder was 250 cc with a diurnal interval between micturitions of about 3 hours. 79% of patients experienced an urge to micturate. The mean frequency of nocturnal micturition was 1.6. Diurnal continence was perfect in 100% of patients, while nocturnal continence was excellent in 78% of cases and good in 18% of cases, while one patient (4%) suffered from nocturnal incontinence. Hautmann enterocystoplasty is therefore an excellent technique for bladder replacement, ensuring diurnal and nocturnal continence for the great majority of patients.

Biometry of infrarenal inferior vena cava measured by cavography. Clinical applications.

Placement of a transvenous vena cava filter has became a common way to control recurrent pulmonary embolism. However few studies have been reported on the diameter of the infrarenal inferior vena cava (IIVC) where the device is usually placed. This study based upon 100 cavographies has showed the calculated average diameter of IIVC was 20.9 mm (range 12-27 mm) in its middle part and 21.3 mm (range 10-31 mm) in its terminal end. The calculated average IIVC length was 96 mm (range 80.3-142 mm). There was no statistical correlation between caval size and age, sex, height, weight and corporeal area. There was a statistical difference of left renal vein location between patients presenting with lumbar arthrosis and those without. We discuss different methods to measure IIVC in particular tomodensitometry. CT scans reviewed in our department show that the largest diameter of IIVC is not in a frontal plane and that the width seen on cavography is the projection of the largest diameter on the film. Therefore, the range of the real caval diameters is greater than indicated above.
