Background Postpartum stress incontinence (PPSI) is a common issue affecting many women after childbirth, marked by involuntary leakage of urine during activities that increase abdominal pressure. This study examines the prevalence and risk factors associated with PPSI, aiming to identify patterns that could guide preventive care. Methodology A cross-sectional study was conducted at Liaqat Memorial Hospital, affiliated with KMU IMS, Kohat, from January 2023 to January 2024. A total of 100 postpartum women were surveyed regarding their urinary incontinence symptoms and related obstetric and demographic characteristics. Data were collected through structured questionnaires and analyzed using statistical tests to assess associations between PPSI and various risk factors, including delivery mode, BMI, labor duration, and instrumental assistance during delivery. Results Conclusion Keywords The prevalence of PPSI was significantly higher among women who had vaginal deliveries (40%) compared to those with cesarean deliveries (15%), with a p-value of 0.01. Higher BMI (p = 0.03) and prolonged labor duration (p = 0.04) were also significantly associated with an increased risk of PPSI. However, birth weight of the newborn and socioeconomic status did not show significant associations with PPSI in this sample. This study underscores the importance of considering delivery mode, BMI, and labor duration as critical factors in PPSI risk. Early identification of at-risk women, along with targeted preventive strategies proper care and support of the pelvic floor during delivery, avoiding prolonged labor can help reduce PPSI frequency and enhance maternal health outcomes. Increased awareness and proactive care are essential in addressing PPSI as a vital component of postpartum well-being.
