A system for monitoring a volume of a bladder during a surgical procedure. The system includes one or more processors; and a memory that is communicatively coupled to the one or more processors and stores one or more sequences of instructions, which when executed by one or more processors causes steps to be performed comprising: receiving information of a maximum volume of the bladder before the surgical procedure; receiving one or more ultrasound images from an ultrasonic scanner; based on the one or more ultrasound images, determining a volume of the bladder; comparing a maximum volume of the bladder to the determined volume of the bladder; and responsive to a difference between the maximum volume and determine volume of the bladder exceeding a threshold, issuing a warning associated with the difference.
