A new study in 123 women with stress urinary incontinence has examined the effect on urinary outcomes of incision location in sling surgery, showing that the one-half rule for calculating the incision point is superior to the one-third incision. Patients received the transobturator tape (TOT) with the incisions at either one-third the sonographically measured urethral length (comparable to a retropubic approach) or at one-half this length (more proximal). The cure rates were higher for the one-half group (83.6%) than the one-third group (62.9%) and this effect was enhanced in women with normal urethral motility.
