A test module is provided for coupling with a control device to form a portable system for assessing urinary function. The test module includes a test module housing, at least one coupling element for removably coupling the test module to the control device, a tubing assembly located at least partially within the test module housing, and a pressure interface in fluid communication with at least a portion of the tubing assembly. When the test module is coupled to the control device, the pressure interface is positioned relative to a pressure sensor in the control device so as to transmit pressure data thereto. The tubing assembly may also couple with a pump device in the control device so as to enable the pump device to pump fluid through the tubing assembly.
