MP61-10: Urinary Functional Outcomes of Radical Prostatectomy vs. Radiation Therapy for Prostate Cancer Following Holmium Laser Enucleation of the Prostate (HoLEP)
Introduction: Prostate cancer is a well-documented finding in Holmium Laser Enucleation of the Prostate (HoLEP); however, there is little data on the outcomes of patients who underwent HoLEP followed by definitive therapy for subsequent prostate cancer diagnosis. We sought to compare the urinary functional outcomes after undergoing radical prostatectomy or external beam radiation for prostate cancer following HoLEP. Methods: All patients from 2010 to 2021 at Indiana University and Baylor Scott and White Hospitals who underwent radiation or prostatectomy for treatment of prostate cancer after HoLEP were included. We performed a retrospective analysis of their urinary function with greater than 1-year post-treatment American Urological Association Symptom Index (AUA), Quality of Life (QOL), and incontinence follow up. Incontinence was defined as patient reported leakage of any urine. Results: There were 33 radical prostatectomy and 36 radiation patients who met the inclusion criteria. There was no statistical significance between the mean AUA scores of greater than 1-year post-prostatectomy patients (7.69) and post-radiation patients (8.08) (p=0.8175). Similarly, there was no statistical significance between the QOL scores of greater than 1-year post-prostatectomy patients (1.96) and post-radiation patients (2.00) (p=0.9175). There is a statistically significant decrease in complaints of incontinence in greater than 1-year post-radiation patients (28%) compared to post-prostatectomy patients (73.3%) (p=0.0017). There was also a significant difference between mean age of the prostatectomy group (66.4 years) and the radiation group (75.3 years) (p < 0.001). There was no significant difference in BMI, pre-HoLEP prostate size, pre-HoLEP AUA score, or pre-HoLEP QOL score between the groups. Conclusions: Radical prostatectomy and radiation provide similar AUA and QOL symptom scores for prostate cancer patients who previously underwent HoLEP, with radiation associated with decreased incidence of incontinence. Patients specifically concerned with the risk of incontinence following prostate cancer treatment may consider the increased risk from a prostatectomy. SOURCE OF Funding: None
