description Background: The relationship between the size of bullae and pneumothorax recurrence is controversial. The aim of this study was to retrospectively evaluate the role of blebs or bullae in predicting ipsilateral recurrence in young patients experiencing their first episode of primary spontaneous pneumothorax (PSP) who underwent conservative treatment. Methods: A total of 299 cases of first-episode PSP were analyzed. The status of blebs or bullae was reviewed on high-resolution computed tomography (HRCT). The dystrophic severity score (DSS; range, 0 to 6 points) was calculated based on HRCT. Results: The 5-year recurrence rate was 38.2%. In univariate analysis, age (
