[Urodynamic changes after transobturator suburethral tape]. / Modifications urodynamiques après pose d'une bandelette sous-urétrale trans-obturatrice.

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.

[Multifocal urothelial tumors and renal autotransplantation]. / Tumeurs urothéliales multifocales et auto-transplantation rénale.

The authors report the case of a patient with multiple urothelial tumours only sparing the superior left ureter and the urethra. The complex treatment consisted of a combination of resection of the entire urinary tract, except for the left kidney and its proximal ureter that was transplanted into the right iliac fossa, after ex vivo partial pyelectomy. This complex treatment regimen avoided the need for dialysis with a good functional and oncological result, three years later.

[Emphysematous cystitis complicated by bladder perforation: diagnosis and treatment of a rare case]. / Cystite emphysémateuse compliquée de perforation vésicale : diagnostic et traitement d'une observation rare.

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.
