[Urodynamic changes after transobturator suburethral tape].

INTRODUCTION: Prospective study of urodynamic changes induced by transobturator insertion of suburethral tape a dip-stick under-urethral. MATERIALS AND METHODS: 25 women with pure (12) or mixed (13) stress urinary incontinence were operated by this technique, allowing urodynamic assessment and completion of the MHU urinary disability questionnaire. Three operators performed these 25 tape insertions in 2 centres (Amiens and St Quentin hospitals) according to a standardized technique. Six months after the operation, patients were reviewed by clinical examination, MHU questionnaire and urodynamic assessment. RESULTS: The cure rate at 6 months was 80% (20 patients) and the improvement rate was 20% (5 patients). The maximum flow rate decreased from 23.6 ml/s to 18.9 ml/s (p = 0.02) and the post-voiding residual volume increased from 26.8 ml to 66.8 ml (p = 0.01). Urethral resistance increased from 0.16 to. 0.25 (p = 0.03) and maximum closure pressure increased from 43.8 to 47.5 cm H2O (p = 0.02). These results demonstrate the obstructive nature of this suburethral tape. The results of the MHU questionnaire showed accentuation of dysuria (p = 0.04) and improvement of stress urinary incontinence (p < 0.001). CONCLUSION: This prospective study confirms the efficacy of this technique, but analysis of the urodynamic studies and the MHU questionnaire demonstrates obstruction. Long-term surveillance of these patients by uroflowmetry and residual urine appears to be useful to detect possible progression to chronic urinary retention.

[Emphysematous cystitis complicated by bladder perforation: diagnosis and treatment of a rare case].

Emphysematous cystitis is a rare disease mainly encountered in poorly controlled diabetics, immunodepressed patients or patients with infravesical obstruction. The pathophysiology of this disease is characterized by the formation of carbon dioxide (CO2) present in the lumen and/or bladder wall, derived from bacterial fermentation of carbohydrates. The bacteria most frequently responsible are facultative aerobes-anaerobes (Escherichia coli) and more rarely strict anaerobes (Clostridium perfringens). The authors report a case of emphysematous cystitis in a context of pelvic trauma and fracture of the pelvis, complicated by secondary bladder rupture. The diagnostic and therapeutic aspects are discussed.

[Natural history of a suspicious renal mass in a patient with gastric cancer: how to evaluate the risk of multiple primary tumours (MPT)?].

The coexistence of several tumours in the same patient is a rare phenomenon and corresponds to the multiple primary tumour (MPT) syndrome. The most frequently diagnosed MPT include gastrointestinal tumours associated with urological tumours. Overexpression of the STAG1 gene could explain the development of several solid tumours and could be the origin of the multiple primary tumour syndrome. A suspicious renal mass discovered at the same time as a documented cancer is usually a malignant lesion and may justify combined radical surgical treatment. The authors report the natural history of a suspicious renal mass in a patient with primary gastric tumour corresponding to a MPT syndrome. They recall and discuss the epidemiology, pathophysiology, diagnosis and treatment of MPT.
