[Bariatric surgery, calcium oxalate urinary stones and oxalate nephropathy].

Bariatric surgery is now recognized as a sure and effective way for weight reduction in morbid obesity. However some procedures induce intestinal malabsorption leading to enteric hyperoxaluria. So bariatric surgery could place these patients not only at risk for nephrolithiasis but also for oxalate induced nephropathy and chronic renal failure.

[Cure of complex post-irradiation uro-genital fistulae].

The authors report two cases of complex radiation induced urogenital fistulae (vesicovaginal and combined rectovaginal), which were closed successfully at the second attempt with complete restitution of bladder function, without any urinary diversion using colpocleisis in one patient. They mention the necessity of bringing a new source of blood supply into the fistula repair area. Then, they review the different extensive procedures used to ensure this result: small bowel graft, omentopexy to reinforce the suture lines, fibroadipose tissue from the labia majora (Martius' operation).
