Prevalence of varicocele decreases with increasing body mass index. One explanation is increased adipose tissue preventing compression of the left renal vein. Another explanation is decreased detection due to adipose tissue in the spermatic cord. The decrease in varicocele prevalence as a function of body mass index regardless of varicocele grade suggests this explanation is less likely.

In our patient population the short-term failure rate for anterior vaginal wall prolapse using porcine dermis interposition graft was higher than that for traditional anterior colporrhaphy or polypropylene mesh. In addition, the incidence of vaginal extrusion of porcine graft was unacceptably high. Porcine dermis is a less suitable material for cystocele repair than polypropylene mesh or traditional anterior colporrhaphy. Prospective, randomized trials are necessary to determine the true efficacy and complication rates of these graft materials for anterior vaginal wall prolapse repair.
