Unusual site of graft erosion after abdominal sacrocervicopexy.

Large fasciomuscular damage of the feminine pelvic floor resulting in pelvic organ prolapse constitutes a challenge for surgical reconstruction.Between 2005 and 2010, ten women aged 47-75 years were treated by abdominoperineal implantation of polypropylene mesh for modified sacral perineocolporectopexy and subsequently followed up. They were suffering from enterocele (9), genital prolapse (8), descending perineum (5), rectal prolapse (4), and rectocele (3). Five women were incontinent (mean Wexner 9) and six had incomplete rectal evacuation. Defecography revealed enterocele III (5) and II (4). Magnetic resonance (MR) diagnosed descending perineum in five patients (mean 3.8 cm).Permanent reconstruction of the pelvic floor and remission of organ prolapse was achieved at 12-months of follow-up in all except one patient. There were two small vaginal mesh erosions and one hematoma within the pelvic floor. Improvement at rectal emptying and anal incontinence (mean Wexner 4) were found.Modified sacral perineocolporectopexy is effective in the treatment of complex pelvic floor anatomical defects and organ prolapse. Improvements in rectal emptying, pelvic feeling of heaviness, and dyspareunia were achieved. The procedure was safe and characterized by good implant tolerance and a low rate of complications.

Protective effect of vitamin E on the response of the rabbit bladder to partial outlet obstruction.

PURPOSE: There is increasing evidence that ischemia/reperfusion is a major etiological factor in the progression of bladder dysfunction after partial outlet obstruction. If this evidence is correct, treatment with an antioxidant should be beneficial in rabbits subjected to partial outlet obstruction. We designed the current study to determine if diets high in alpha-tocopherol protected the rabbit bladder against dysfunction induced by partial outlet obstruction. MATERIALS AND METHODS: A total of 32 rabbits were separated into 4 groups of 8. Groups 1 and 2 were placed on a diet enriched with 1,000 IU/kg. alpha-tocopherol, and groups 3 and 4 were fed a regular diet containing 44 IU/kg. alpha-tocopherol. After 4 weeks partial outlet obstruction was created in groups 1 and 3, while groups 2 and 4 underwent sham operation. After 4 weeks of obstruction the rabbits were anesthetized and the bladders were rapidly excised. Four longitudinal strips obtained from the bladder body were used for contractility studies. The balance of the bladder body was separated between muscle and mucosa. Each section was frozen and stored at -70C for analysis of malondialdehyde as a measure of peroxidation and for alpha-tocopherol concentrations. RESULTS: Feeding rabbits a diet high in alpha-tocopherol resulted in significant protection against the development of contractile dysfunction after partial outlet obstruction. The protective effect of alpha-tocopherol was related to significantly decreased malondialdehyde and significantly increased tissue concentrations of alpha-tocopherol. CONCLUSIONS: These data indicate that a major etiology of bladder dysfunction secondary to partial outlet obstruction is related to free radical generation and resultant membrane lipid peroxidation.
