Background. One of the common treatments for prostate cancer is radical prostatectomy, which is performed in different ways. One of the advantages of the nerve bundle preservation method is better exposure, decrease in rectal damage the lower rectum. In addition, the possibility of a positive margin is less. Therefore, this study aimed to examine the results of using the high anterior release (HAR) technique in radical open prostatectomy surgery. Methods. In this cross-sectional study, after examining patients and their entry into the study and obtaining their medical records, questions were asked to assess erectile function and urinary incontinence. The prostate-specific antigen level was checked before and after the operation. In addition, the average surgical time, blood loss, and hospitalization time were evaluated. Finally, the data were analyzed using the SPSS statistical analysis program, version 19. Results. In this study, 102 patients underwent radical prostatectomy, with an average age of 62.33 years. About 56.9% of patients had stage t2b. During the 6-month follow-up after surgery, 70.5% of patients had complete urinary continence. Data analysis demonstrated that there is a direct relationship between urinary incontinence, with a history of radiotherapy (P<0.001), and the stage of the disease (P=0.019). After surgery, 61.8% of patients were satisfied with the erection function . Conclusion. The results of this study revealed that urinary incontinence and erectile dysfunction are relatively common complications of this surgery. However, compared to other similar studies, the incidence of these two complications is lower. Practical Implications. Urinary incontinence and erectile dysfunction are relatively prevalent complications of radical prostatectomy surgery using the HAR technique. Nonetheless, the incidence of these two complications is lower compared to other similar studies. [ABSTRACT FROM AUTHOR]
