Combined pressure, flow, EMG and X-ray studies for the evaluation of neurogenic bladder disturbance: technique

A set-up for combined pressure, flow, EMG and X-ray recording is presented. Some efforts are undertaken to keep artefacts by manipulation, instrumentation and by the investigation itself as low as possible. Using a specially designed, plastic made, radiolucent micturition chair this set-up is especially suitable for the urodynamic evaluation of the lower urinary tract in paraplegics, in myelomeningoceles and other handicapped persons. More than 90 urodynamic studies have been carried out in this way during the last 2 years without any complication whatsoever.
