This invention relates to the field of postoperative functional recovery prediction technology, specifically a method for predicting the recovery of voiding function after orthotopic neobladder surgery based on multimodal data. The method includes the following steps: acquiring volume, urine flow rate, and urethral pressure data and synchronizing them in time; organizing data according to the voiding cycle in conjunction with imaging information; dividing the voiding cycle into stages and assessing the recovery progress; and determining whether the recovery trend has deviated. In this invention, by synchronizing and integrating volume, urine flow rate, and urethral pressure data in time and organizing them uniformly with the imaging sequence according to the voiding cycle, multi-source information is continuously correlated within the same time axis. Based on the ratio of volume to flow rate and pressure abnormality markers, the dynamic changes in the voiding process are characterized. The recovery progress is assessed by combining stage division and trend fitting, and the stability and deviation of the continuous cycle trend are identified. This transforms the judgment of voiding function recovery from a static conclusion to a dynamic prediction with sustainable tracking, improving individual adaptability and clinical early warning value.
