Objectives: The current study aimed to study the presenting features of Primary Spontaneous Pneumothorax (PSP) patients including demographic (gender, age, smoking, height and weight, Body mass index (BMI)), symptoms and seasonality among adult patients in KKUH during the period from 2010 to 2016. To describe the recurrence of PSP and length of hospital stay in patients who were managed surgically in KKUH during the period from 2010 to 2016.
