简要总结
Many patients may face long-term urinary side effects following stereotactic body radiation therapy (SBRT), including increased urinary frequency, dysuria, and nocturia. The investigator hypothesizes that Urolift, which represents a novel minimally invasive therapy, may reduce acute and long-term urinary toxicity and side effects of radiation therapy (SBRT).
详细描述
Urolift is a standard of care treatment for BPH. It involves the placement of a stainless-steel urethral end piece tethered to a capsular tab to the left and right side of the prostatic urethra approximately 1.5cm distal to the bladder neck. It pulls and maintains the opening of a continuous channel through the prostatic urethra. A previous study examined the effect of Urolift on urinary symptoms and urinary medications at six months post-procedure.Urolift was associated with significant urinary improvements measured by IPSS and quality of life questionnaires and a reduction in the use of total medication as well as alpha-blockers and beta-3 agonists.

研究组 & 干预措施
Urolift
This is a single-arm study involving 1 year of follow-up. Study intervention involves a one-time administration of Urolift prior to SBRT for prostate cancer treatment.
干预措施: Urolift (Device)
结局指标
主要结局
Change in MSHQ through study completion, an average of 1 year
时间窗: Through study completion, an average of 1 year
Patients will take the Men's sexual health questionnaire (MSHQ) to further evaluate patients' ability to have sex with their partner(s) or masturbate through study completion, an average of 1 year. Overall, study subjects will be assessed for possible change in hypogonadal, sexual function, and pain symptoms. Scores range from 16 to 125. Lower scores are considered most symptomatic, higher scores are least symptomatic.
Change in OAB-SF score through study completion, an average of 1 year
时间窗: Through study completion, an average of 1 year
Patients will use a overactive bladder short form (OAB-SF) to describe their overactive bladder symptoms through study completion, an average of 1 year, to see if there is any changes in symptoms. The OAB-q SF has 2 main subscales: Symptom bother and Health-Related Quality of Life (HRQOL). The two subscales are summed separately and transformed into scores ranging from 0 to 100. A higher score on the symptom bother scale indicates a greater symptom severity and a higher score on the HRQOL scale indicates a better HRQOL, so they are inversely related to each other. Since the OAB-q SF has no total score, higher scores indicate more severe symptoms or better quality of life, respectively. Lower scores indicate less severe symptoms or worse quality of life respectively.
Change in IPSS scores from baseline and one year post treatment
时间窗: At baseline and one year post treatment
Patients will take a International Prostatic Symptom Score (IPSS) questionnaire to evaluate symptom severity at baseline and 1 year post treatment. IPSS scores range from 1 to 35, with 1-7 indicating mild symptoms, 8-19 indicating moderate symptoms, 20-35 indicating severe symptoms.
Change in IIEF score through study completion, an average of 1 year
时间窗: Through study completion, an average of 1 year
Patient will take the International Index of Erectile Function (IIEF) to evaluate changes in sexual function of patients through study completion, an average of 1 year. IIEF scores range from 6 to 30. IIEF lower scores indicate severe erectile dysfunction, while higher scores indicate mild/no erectile dysfunction.
Change in VAS score through study completion, an average of 1 year
时间窗: through study completion, an average of 1 year
Patients will use a visual analog scale (VAS) to describe their pain through study completion, an average of 1 year, to see if there is any changes in pain post treatment. Self-assessed maximum pain reported using a 0-100mm visual analog scale, where 100 signifies maximum pain and 0 signifies no pain.
Change in SF-12 score through study completion, an average of 1 year
时间窗: Through study completion, an average of 1 year
Patients will use a short form 12 (SF-12) survey to measure their quality of life through study completion, an average of 1 year, to see if there is any changes. Scores range from 0 to 100, with higher scores indicating better physical and mental health functioning. A score of 50 or less on the PCS-12 has been recommended as a cut-off to determine a physical condition; while a score of 42 or less on the MCS-12 may be indicative of 'clinical depression'.
