Summary: The Authors have examined 20 patients with genuine stress incontinence and urogenital prolapse and 20 control sujects searching a difference between static and dynamic condition of the pelvic floor. They used a simple device to study the mean position of the perineal plane both at rest and under switch. In incontinent patients the perineal plane is always below the bituberal plane ( + 1.17 cm at rest and + 1.32 cm straining ). These values are on a higher plane in the control subjects ( - 0.64 cm at rest and + 0.48 cm upon straining ). These differences have an higly significant statistical value ( P=0.0002 and P=0.001 )
