ABSTRACT:
The apparatus is worn by a user and includes means for automatically scanning the bladder of the user with ultrasound signals. The returning signals are used to calculate the volume of urine in the bladder and also to calculate the actual surface area of the bladder. The theoretical surface area of a spherical bladder having the said calculated volume is then determined. A surface area index (SAI) is then determined as follows: ##EQU1## The SAI value is an indication of the roundness of the bladder and hence the pressure within the bladder.
