[The mediating effects of self-efficacy between symptom experience and quality of life in prostatic hyperplasia patients after cystostomy]

Objective: To evaluate the symptom experience of patients with benign prostatic hyperplasia and bladder fistula. Exploring the mediating effect of self-efficacy on the relationship between symptom experience and quality of life in patients with benign prostatic hyperplasia undergoing long-term indwelling cystostomy.

Methods: This study used a cross-sectional survey design. Patients with prostatic hyperplasia with cystostomy in the Urology department of General Hospital of Eastern Theater Command from January 2020 to February 2023 were selected, and relevant data were collected by IPSS, IIEF-5, HAMD, GSES, and quality of life score scale for statistical analysis. We then construct a structural equation model to evaluate the mediating effect of self-efficacy between symptom experience and quality of life.

Results: The average score of IPSS was (22.55±8.26) ; the average score of IIEF-5 was (10.54±4.10) ; the average score of HAMD was (6.82±2.35) ; the average score of self-efficacy was (20.80±8.65) ; and the average score of quality of life was (71.65±12.55) . Symptom experience was significantly negatively correlated with self-efficacy and quality of life( r=－0.496 , P<0.01；r=－0.518 , P<0.01) . Self-efficacy was significantly positively correlated with quality of life( r= 0.412，P<0.05). Symptom experience significantly negatively affected quality of life through self-efficacy (Effect = －0.218，P = 0.014) .

Conclusion: Self-efficacy is positively correlated with the quality of life of patients with benign prostatic hyperplasia who have long-term indwelling cystostomy tube. Nursing staff can improve the level of self-efficacy of patients by implementing corresponding interventions.
