Measuring urine production and other urine-related parameters

A method for use with a conduit that is configured to carry urine downstream from a bladder of a subject, the method comprising:

• controlling one or more force-applying elements, which are reversibly coupled to the conduit, such that the force-applying elements apply force to the conduit, thereby forcing the urine from the conduit in a downstream direction;
• and
• calculating a volume of the urine that was forced, based on the controlling of the force-applying elements.

Apparatus for use with one or more force-applying elements, the apparatus comprising:

• at least one tube, configured to carry urine that flows downstream from a bladder of a subject via a urinary catheter that catheterizes the subject;
• and
• a conduit section configured to couple to the tube in fluid communication with the tube and to reversibly couple to the force-applying elements so as to facilitate the force-applying elements applying force to the conduit section, thereby forcing the urine from the conduit section in a downstream direction.
