Computer-assisted urodynamics.

We have assembled a computer hardware system and have written software programs that convert analogue urodynamic input to digital data. This has allowed for 1) extremely accurate recording of urodynamic events with a higher frequency response than existing units, 2) data storage of urodynamic events in digital form on floppy disks, 3) retrieval and plotting of urodynamic studies during and at times remote from the study performance, and 4) manipulation of the parameters in the urodynamic study for patient care and research purposes. Software is now available for the performance of cystometrograms (volume, total pressure, intravesical pressure and dP/dt), electromyograms, flow studies and dynamic renal pelvic pressure testing. Programs are in the development phase for computer analysis of urodynamic studies.
