[Treatment of ureteral calculi: report of 152 calculi].

OBJECTIVE: To define the therapeutic approach to ureteric stones. MATERIAL AND METHODS: 137 patients with 152 ureteric stones were treated between January 1990 and January 1997. Sixty seven stones (44%) were situated in the lumbar ureter, 16 stones (10%) were in the iliac ureter, 69 stones (46%) were in the pelvic ureter. These stones were treated by extracorporeal shock-wave lithotripsy (ESWL), ureteroscopy and, more rarely, ureterotomy. RESULTS: One hundred and three stones were treated in a single session, while 31 required two ESWL sessions. Treatment eliminated 82% of ureteric stones: 89% of lumbar ureteric stones, 31% of iliac stones and 85% of pelvic stones. Ureteroscopy was performed as first- or second-line treatment in 34 cases. It successfully treated 97% of ureteric stones: 100% of pelvic and lumbar stones and 91% of iliac stones. Three patients were successfully treated by ureterolithotomy for a lumbar ureteric stone and two for iliac ureteric stones. CONCLUSION: SWL is the reference treatment for stones of the lumbar ureter. Ureteroscopy is justified after failure of ESWL for stones of the pelvic and iliac ureter, as it gives excellent results.

[Urinary continence after retropubic radical prostatectomy: retrospective study with self-administered questionnaire].

OBJECTIVES: To precisely evaluate the incidence of urinary incontinence after radical prostatectomy and its impact on quality of life. MATERIAL AND METHODS: A self-administered questionnaire was sent to 116 patients operated between 1987 and 1996. Preoperative and postoperative urinary continence, the time until urinary continence was achieved, the presence of urgent micturition, the degree of discomfort caused by urinary incontinence and associated voiding disorders were assessed. RESULTS: The questionnaire response rate was 96.6%. The urinary incontinence rate (continuous use of pads) was 13.4%. No predictive factor for postoperative urinary incontinence was identified. Urge incontinence was present in 31.3% of cases. 85% of patients claimed to be satisfied with the operation and 95.4% declared that they would be willing to undergo radical prostatectomy again. CONCLUSION: The incidence of urinary incontinence after radical prostatectomy is acceptable and the morbidity that it generates is well tolerated and has little impact on quality of life.

[Sacral tuberculous osteitis].

The authors report a case of a 5 year old child suffering from isolated sacral tuberculosis which presented as sudden and total loss of function of the left leg. The rarity of this bony site, and the recurrence at nine months of a presacral abscess after 9 months of anti-tuberculous treatment in an HIV negative child, vaccinated with BCG, justify the presentation of this observation.

[Sideroses of alveolar macrophages. Analysis of a continuous series of 360 bronchoalveolar lavages].

360 consecutive bronchoalveolar lavage fluids (BAL) were studied using semi-quantitative method described by GOLDE (GOLDE score). 44 hemosiderosis were detected (12%). Most of them corresponded to massive alveolar hemorrhage (AH). Depending on pathological contexts, we distinguished three main groups of AH frequency: a group of high frequency (around 40%), an intermediate group (10%) and a low frequency group with less than 5%. Matching cytological results with clinical and radiological data, revealed that AH was often too late diagnosed because inconstancy of typical clinical and radiological signs. Even with a variable prognosis related to different physiopathological mechanisms, AH evolution is unpredictable. The authors suggest thus BAL cytological examination may systematically include a research of hemosiderosis in AH high frequency groups.

[Mucoepidermoid bronchial carcinoma. Review of the literature apropos of a new case].

Muco-epidermoid bronchial tumours are rare and characterized by the coexistence of epidermoid, mucus-secreting and intermediate cells. The authors report the case of a 22-year old unmarried woman hospitalized for exploration of a febrile dyspnoea related to a right superior lobar atelectasis. Endoscopy showed a smooth, pediculate tumour arising from the right superior lobar bronchus where bronchial biopsy was negative. Right superior lobectomy was performed through thoracotomy and established the diagnosis of muco-epidermoid bronchial tumour. Surgery was followed by radiotherapy of the chest. Over a 5-year follow-up period there was no local or extrathoracic recurrence, and the patient is in good condition.

[Sulfation and mitogenic activities of growth factors in human serum: importance of compounds of molecular weight lower than 1,000 in the global expression of activity of this serum on 3 different cellular types].

A human serum ultrafiltrate contains compounds needed for a maximal expression of sulfation and mitogenic activities of the corresponding retentate. These low molecular weight (less than 1,000) molecules have no effect, by their own, on 35SO4(2-) uptake in chick embryo cartilage, but show a significant synergistic effect with serum growth polypeptides. Tested alone, they display a slight mitogenic activity as measured by 3H-thymidine incorporation in chick embryo fibroblasts or in lymphocytes activated by phytohemagglutinin. Here they also act in a synergistic way on mitogenic activities of growth factors from human retentate. A fraction (P2B), partially purified from human plasma ultrafiltrates, produces the same synergistic response with human retentate in the three cellular systems (cartilages, fibroblasts, activated lymphocytes). However, concentrations which lead to optimum responses are very different according to the cell type studied. These results suggest the existence of several compounds which can each act specifically on a cellular system.
