Video urodynamics

Summary The simultaneous recording of urodynamic parameters and x-ray imaging of the lower urinary tract is the ideal technique for a complex investigation of lower urinary tract function and x-ray morphology. To minimize pain-artefacts by tubes and electrodes, the preparatory measurements, which include the suprapubic insertion of two tubes into the bladder, are done the day before, if necessary, in a short general anaesthesia, the investigation itself is performed the following day without an irritating catheter in the urethra and without pains for the patient (which is especially essential when investigating children). The technical details of a modern videourodynamic system and its advantages for this type of investigation are presented. However, the clinical practice has also revealed some weak points of the system, which need to be improved. The technique together with modern technology guarantees accurate and reproducable information also in childeren.
