A system and method for monitoring bladder and abdominal pressures, and a bladder function recovery system. The method comprises: a bladder pressure collecting unit (1) communicated with a urethral catheter (2) collecting a bladder pressure in real time, and displaying the bladder pressure (201) based on the collected bladder pressure, obtaining an abdominal pressure according to correspondence between the bladder pressure and the abdominal pressure (202) and displaying the abdominal pressure in real time (203). According to the system and method for monitoring bladder and abdominal pressures and the bladder function recovery system, the bladder pressure can be collected in real time, and the abdominal pressure is obtained according to the correspondence between the bladder pressure and the abdominal pressure, so as to monitor the abdominal pressure while monitoring the bladder pressure in real time, thereby solving the technical problem in the prior art that a change of the abdominal pressure cannot obtained in a timely and safe manner. In addition, an ICU patient can undergo bladder function recovery training by using the bladder function recovery device, and a physiological urination process of a human body is simulated, so as to avoid bladder function deterioration.Linvention concerne un système et un procédé de surveillance de pressions vésicale et abdominale, et un système de récupération de la fonction vésicale. Le procédé comprend les opérations suivantes : une unité de collecte de pression vésicale (1) communiquant avec un cathéter urétral (2) collecte une pression vésicale en temps réel, et affiche la pression vésicale (201) sur la base de la pression vésicale collectée, obtient une pression abdominale en fonction de la correspondance entre la pression vésicale et la pression abdominale (202) et affiche la pression abdominale en temps réel (203). Selon le système et le procédé de surveillance de pressions vésicale et abdominale et le système de récupérat
