[Clear cell epithelioma of the kidney in a child. Apropos of a case].

The authors report a case of renal hypernephroma in a child. This is an uncommon tumour which is very rarely diagnosed preoperatively. Its treatment is exclusively surgical. As in adults, the prognosis depends on the stage of the tumour at the time of discovery.

[Role of the unstable bladder in certain pathologies of the lower urinary tract].

The authors report their experience of 57 cases of unstable bladder, 20 cases of which were neurogenic in origin. It is a frequent disease encountered in 19% of cases. The sex ratio is one male/one female. Infants are not spared (17 cases). Unstable bladder is a urodynamic concept; therefore, diagnosis of certitude is based on cystometry. The analytic study enables the authors to underline the clinical symptoms, to establish the urodynamic criteria of detrusor hyperactivity and to enumerate the side effects on bladder and renal function. The different etiologies, organic or functional, of detrusor hyperreflexia are exposed. Finally, the therapeutic possibilities are discussed.

[Urethral instability. Apropos of 26 cases].

The authors report their experience about 26 cases of urethral instability. This dysfunction is not rare; both sexes are involved, children was well as adults. Diagnosis is based on the data of simultaneous urethro-cystometry. Three clinical patterns are recognized: intermittent urinary leakage (6 cases), frequency and urgency (3 cases) and enuresis (17 cases). The urethral instability was pure in 13 cases and associated to detrusor hyperactivity in the other thirteen. But, in one of these the bladder instability was pure. A treatment based on alpha-adrenergic drugs has assured clinical relief and urodynamic stabilization of bladder and urethra.

[Iatrogenic stenosis of the urethra. Apropos of 67 cases].

Iatrogenic causes of stenosis of urethra appear to be increasing in frequency, 67 cases out of a total of 400 patients seen between 1974 and 1981 being of iatrogenic origin. The principal cause is the use of a urethral catheter, since it was the only etiologic factor in 32 cases and the main factor in the remaining patients. Various therapeutic methods are used, preference being given quite clearly to internal urethrotomy. Prevention is of fundamental importance and is based on the less untimely routine use of urethral catheters, particularly after general surgical operations and in intensive care.

[Role of echography in the evaluation of renal masses. Apropos of 65 cases].

65 renal tumours were investigated by echography. The group was made up of 24 simple cysts, 18 hydatid cysts and 23 carcinomas of the kidney. Analysis of these cases led to the following conclusions: 1) Echography should be carried out whenever a tumour syndrome is found by urography. 2) Solid tumours are malignant. They rarely pose any diagnostic problem. For fluid-containing tumours, a parasitic aetiology may be assumed in the presence of characteristic features and whenever the clinical context is suggestive. A simple cyst with a non-echogenic and homogeneous structure is easy to diagnose. The only diagnostic problem which remains is that of tumours with a heterogeneous echostructure. Arteriography is then of great value. 3) In solid tumours, echography must include study of the renal vein, inferior vena cava and liver. 4) The indications of arteriography are hence limited to heterogeneous tumours and carcinomas of the kidney where is particularly useful is assessing venous spread. 5) Taking all tumours together, the reliability rate of echography is 76%. 6) By virtue of its harmless nature and low cost, it has become an examination of choice in the diagnosis of renal tumours.
