Vaginal cone for postmenopausal women with stress urinary incontinence: randomized, controlled trial. Pereira VS, de Melo MV, Correia GN, Driusso P. Climacteric. 2012 Feb;15(1):45-51. Epub 2011 Nov 8.

Add this one to the many previous RCT and Cochrane Review which shows no difference between vaginal weights and PFM exercises as long as the professional exposure is the same.  Otherwise nothing special about this one.  I would like to see a study which compares handing an instruction sheet on PFM exercises to a group of patients and handing vaginal weights (with instructions) to another group of patients.  One of the videos about vaginal weights implies they “cause the PFM instinctively contract”.  I wonder if this is their role.
