The ATOMS system can then be adjusted to suit the patient’s individual requirements by means of the port, which was implanted in the scrotum. The doctor injects the port with fluid, which then travels through the catheter to fill the cushion lying under the urethra. As the cushion fills, the pressure on the urethra softly increases. In future, this correctly-adjusted pressure will allow the patient to better hold the urine. It is likely that several adjustments will be required to find the ideal filling volume for each patient.
