1. A method for diagnosing detrusor instability comprising the steps of:

  • using an insert member having a channel therethrough positioned distal of the urethral sphincter, creating a substantially fluid tight seal to substantially block fluid flow into or out of the urethral canal other than through the channel;

    infusing fluid from a fluid source through the channel in the insert member and into the urethral canal at a location distal of the urethral sphincter;

    measuring a pressure within the urethral canal at a location distal of the urethral sphincter as the fluid is being infused therein,wherein the infusing step further includes infusing fluid until the urethral sphincter opens, and thereafter until at least one detrusor contraction occurs.
