We queried a TriNetX database to evaluate three-year reintervention rates for both procedures. Methods We used the TriNetX US Collaborative Network database and Common Procedural Terminology codes to identify male patients aged 40 years or older who underwent Rezum or UroLift procedures between January 2018 and December 2020. These patients were followed for three years, during which reintervention procedures were analyzed. Propensity-score matching (PSM) and Cox regression model were performed. Results A total of 3,231 patients were included, with 792 undergoing Rezum and 2,439 undergoing UroLift. After PSM, the overall reintervention rates were similar between the two groups (hazard ratio [HR]: 1.19, 95% confidence interval [CI]: 0.82–1.73). Among patients aged ≥65, the Rezum group had a lower reintervention rate (HR: 0.60, 95% CI: 0.37–0.97) than the UroLift group. In contrast, among those aged ≥40 to <65, reintervention rates did not differ between Rezum and UroLift (HR: 1.49, 95% CI: 0.87–2.55). Within the Rezum group, patients aged ≥40 to <65 experienced a higher reintervention rate compared with those aged ≥65 (HR: 2.12, 95% CI: 1.15–3.93), whereas no age-related difference was observed in the UroLift group (HR: 0.85, 95% CI: 0.62–1.17). Conclusion In patients aged ≥65, Rezum was associated with a lower reintervention rate over the three-year follow-up period, whereas among those aged ≥40 to <65, both procedures yielded comparable reintervention rates. Rezum UroLift minimally invasive surgical therapy reintervention rate TriNetX database Figures Figure 1 Figure 2 Figure 3 Purpose Lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH) can be particularly bothersome. In the United States, approximately 30% of men over the age of 50—about eight million individuals—are affected by this condition and require management. 1 Treatment options include medical therapy and surgical intervention. While medical therapy may offer modest improvement over a year, approximately 30% of patients discontinue treatment due to side effects or insufficient symptom relief. 1 , 2 Transurethral resection of the prostate (TURP) remains one of the most common surgical approach and can improve the International Prostate Symptom Score (IPSS) by 14.8 points within a year. However, TURP is also associated with complications, including ejaculatory dysfunction (65%), urinary incontinence (3%), and urethral strictures (7%). 3, 4 Several minimally invasive surgical techniques have been introduced in recent decades to treat BPH. Among these, the Rezum system and UroLift are two of the most widely adopted. The Rezum system, approved by the U.S. Food and Drug Administration (FDA) in 2015, uses water vapor-based thermal energy to treat an enlarged prostate. During the procedure, water vapor is injected through cellular interstices, delivering 540 cal/mL of energy to tissue cell membranes within the treatment area, leading to cell death and tissue necrosis. 5 , 6 The delivery of water vapor thermal energy confines the treatment effect to a targeted area within the prostate’s zonal anatomy. 7 Previous studies have reported large areas of necrosis within the prostate adenoma following water vapor injections. 8 UroLift, approved by U.S. FDA in 2013, is a prostatic urethral lift procedure that rapidly alleviates obstructive symptoms without resecting prostatic tissue. 9 Permanent implants are placed to retract the obstructing lateral lobes, thereby expanding the urethral lumen. 10 Previous studies have shown that UroLift provides both rapid and sustained improvement in symptoms. 9 Both Rezum and UroLift are relatively new minimally invasive treatments that typically require only local anesthesia or mild sedation. They are designed to preserve sexual function without risking retrograde ejaculation, making them particularly beneficial for older patients at higher anesthesia risk or for younger men wishing to maintain an active sexual life. However, data comparing re-intervention outcomes remain limited, and most available evidence comes from single-center studies with small sample sizes. 11 Additionally, an increasing number of men are undergoing prostate-related surgery, yet the impact of age on surgical outcomes for Rezum and UroLift remains unclear. Therefore, the aim of this study was to evaluate reintervention rates for both procedures using the TriNetX database. Methods Data Sources The TriNetX, LLC database, established in 2013, includes data from over 190 healthcare organizations across approximately 30 countries. By leveraging real-world data, TriNetX enhances trial design efficiency and generates robust evidence to address global health challenges. The database provides comprehensive information on patient demographics, diagnoses, medication records, surgical procedures, and laboratory test results, all coded using standardized systems. The TriNetX platform adheres to the US Health Insurance Portability and Accountability Act and the General Data Protection Regulation. To date, thousands of peer-reviewed publications have utilized TriNetX data. In addition, use of TriNetX in this study was approved by the Institutional Review Board of Shin Kong Wu Ho-Su Memorial Hospital (20250106R). All data collected from the TriNetX US Collaborative Network were current as of February 2025. In the TriNetX database, human ethics approval and consent-to-participate declarations are not applicable. Study design and cohorts We performed a retrospective, observational cohort study using the TriNetX US Collaborative Network database. Figure 1 . shows the study flow chart. Using International Classification of Diseases 10th (ICD-10) and current procedural terminology (CPT) codes, we identified men aged 40 years or older who underwent either Rezum (53854) or UroLift (52441, 52442) from January 2018 through December 2020. Patients were excluded if they had a history of prostate cancer or had previously undergone prostate-related surgery—such as UroLift, Rezum, TURP (52601), photoselective vaporization of the prostate (PVP) (52648), holmium laser enucleation of the prostate (HoLEP) (52649), transurethral needle ablation (TUNA) (53852), transurethral microwave thermotherapy (TUMT) (53850), transurethral incision of the prostate (TUIP) (52450), or waterjet ablation (0421T). In addition, patients who died during the three-year follow-up period were excluded. A total of 3,231 patients met the inclusion criteria, comprising 792 in the Rezum group (Cohort 1) and 2,439 in the UroLift group (Cohort 2). All patients were followed for three years, during which reintervention procedures were analyzed. Age, serum prostate-specific antigen (PSA) levels, and body mass index (BMI) were collected for the study population. For subgroup analysis, patients were categorized into two age groups: ≥40 to < 65 years and ≥ 65 years older. One-to-one propensity score matching (PSM) was used to minimize potential confounding factors and avoid misleading conclusions. Age, BMI and serum PSA levels, which strongly influence outcomes, were matched to ensure no significant baseline differences between the comparison groups. This statistical approach allows for a more robust comparison of the two cohorts. Study outcomes The study outcome was the occurrence of any reintervention procedure during the 3-year follow-up. We used CPT codes to identify any reintervention procedures performed after the initial treatment. These reinterventions included UroLift, Rezum, TURP, PVP, HoLEP, TUNA, TUMT, TUIP, and waterjet ablation. Statistical analysis Continuous variables were reported as means ± standard deviation (SD). Nearest-neighbor matching was performed using the built-in TriNetX function to minimize confounding effects on baseline characteristics. During the follow-up period, Cox proportional hazards regression and Kaplan–Meier survival analyses were conducted on the TriNetX platform. The Cox model generated hazard ratio (HR) with corresponding 95% confidence interval (CI) for each outcome. In the Kaplan–Meier analysis, differences in event-free survival between groups were evaluated using a log-rank test. A two-sided P-value < 0.05 was considered statistically significant. All figures in this manuscript were created using R software (version 4.3.0, Free Software Foundation Inc.). Results A total of 3,231 patients were included in the analysis, with 792 undergoing Rezum (Cohort 1) and 2,439 undergoing UroLift (Cohort 2). Baseline characteristics are presented in Supplementary Table 1 . Comparing to patients in Cohort 2, patients in Cohort 1 were older (68.2 ± 8.1 vs. 66.3 ± 8.8 years, p < 0.001) and had lower BMI (28.4 ± 4.7 vs. 29.1 ± 5.3, p < 0.001), whereas serum PSA levels did not differ significantly between the two groups (2.5 ± 2.8 vs. 2.2 ± 5.5, p = 0.188). After one-to-one PSM, each cohort consisted of 784 patients. As shown in Supplementary Fig. 1 and Table 2 a, there was no significant difference in the three-year reintervention rate between the two groups, both before (Log-rank test, p = 0.751) and after (HR: 1.19, 95% CI: 0.82–1.73; Log-rank test, p = 0.355) PSM.

Supplementary Table 1. Comparison of Baseline Demographic Characteristics in Rezum and UroLift Cohorts Before and After Matching Patients were stratified into two age groups (≥ 40 to < 65 years and ≥ 65 years). Among patients aged ≥ 65 years, there were 532 in Cohort 1 and 1,464 in Cohort 2 before matching. As shown in Table 1 , patients in Cohort 1 were older (72.7 ± 5.3 vs. 72.1 ± 5.2 years, p = 0.030) and had lower BMI (28.0 ± 4.7 vs. 28.6 ± 4.9, p = 0.035), while serum PSA levels were comparable between groups (2.8 ± 3.2 vs. 2.4 ± 6.9, p = 0.336). After PSM, each cohort included 530 patients. As illustrated in Table 2 a, Supplementary Fig. 2a and Fig. 2 a, among patients aged ≥ 65, the Rezum group demonstrated a significantly lower reintervention rate compared to the UroLift group, both before (Log-rank test, p = 0.015) and after (HR: 0.60, 95% CI: 0.37–0.97; Log-rank test, p = 0.037) PSM.

BMI: Body Mass Index Among those aged ≥ 40 to < 65, there were 260 patients in Cohort 1 and 975 in Cohort 2 before matching. As shown in Table 1 , patients in Cohort 1 were older (59.1 ± 4.2 vs. 57.6 ± 5.1 years, p < 0.001) and had lower BMI (28.6 ± 4.8 vs. 29.8 ± 5.8, p = 0.008), while serum PSA levels were similar between groups (2.0 ± 1.9 vs. 1.8 ± 2.0, p = 0.292). After PSM, each cohort consisted of 260 patients. As illustrated in Supplementary Fig. 2b , among patients aged ≥ 40 to < 65, the Rezum group had a significantly higher reintervention rate than the UroLift group before PSM (Log-rank test, p = 0.004). However, as shown in Table 2 a and Fig. 2 b., after matching, the difference was not statistically significant (HR: 1.49, 95% CI: 0.87–2.55; Log-rank test, p = 0.147). We further examined procedure-specific outcomes by age group. As shown in Supplementary Table 2 , among patients in the Rezum group, those aged ≥ 65 had higher serum PSA levels (2.8 ± 3.2 vs. 2.0 ± 1.9, p = 0.004) but similar BMI (28.0 ± 4.7 vs. 28.6 ± 4.8, p = 0.156) compared to those aged ≥ 40 to < 65. In Supplementary Table 2 , among patients in the UroLift group, those aged ≥ 65 also had higher serum PSA levels (2.4 ± 6.9 vs. 1.8 ± 2.0, p = 0.051) but lower BMI (28.6 ± 4.9 vs. 29.8 ± 5.8, p < 0.001) compared to those aged ≥ 40 to < 65. As shown in Table 2 b, Supplementary Fig. 3a and Fig. 3 a, those aged ≥ 40 to < 65 had a higher reintervention rate than those aged ≥ 65, both before (Log-rank test, p < 0.001) and after (HR: 2.12, 95% CI: 1.15–3.93; Log-rank test, p = 0.014) PSM. In contrast, in the UroLift group (Table 2 b, Supplementary Fig. 3b and Fig. 3 b), no age-related difference was observed within the UroLift group, both before (Log-rank test, p = 0.191) and after (HR: 0.85, 95% CI: 0.62–1.17; Log-rank test, p = 0.325) PSM. Discussion This study confirms that age is an independent factor influencing the effectiveness of Rezum. Our findings indicate that among patients aged ≥ 65 years, Rezum was associated with a lower reintervention rate than UroLift. In contrast, for those aged ≥ 40 to < 65 years, there was no significant difference in reintervention rates by procedure. Overall, the three-year reintervention rates were similar for Rezum (7.2%) and UroLift (8.3%). Notably, in patients aged ≥ 65 years, the reintervention rate was 4.9% with Rezum compared to 8.8% with UroLift, whereas for those aged ≥ 40 to < 65 years, the rates were comparable (11.9% vs. 7.3%). While previous studies have evaluated both Rezum and UroLift, the impact of patient age on their surgical outcomes remains unclear. In a sham-controlled trial of Rezum, the five-year surgical retreatment rate was 4.4% among 135 patients (mean age 63.0 ± 7.1 years). 12 In contrast, the L.I.F.T. study reported a 13.6% surgical retreatment rate at five years for 140 UroLift patients (mean age 67.0 ± 8.6 years). 13 , 9 An indirect comparisons suggest Rezum may yield lower reintervention rates, as reflected in a three-year comparison by Elterman et al. (4.4% vs. 10.7%) and a prospective two-year study (0% vs. 8.1%)—both favoring Rezum over UroLift. 14 , 11 Although most studies have reported lower reintervention rates with Rezum compared to UroLift, our findings indicated comparable rates between the two procedures. Notably, the mean age in our cohort was higher than in previous studies (68.2 ± 8.1 years for the Rezum group and 66.3 ± 8.8 years for the UroLift group). In a cohort of 256 patients receiving Rezum therapy, there was no significant difference in 4-year surgical reintervention rates between those aged ≥ 65 and those < 65 (11.9% vs. 5.1%, p = 0.06). 15 However, the study included heterogeneous prostate volumes (median 49.5 ml for patients ≥ 65 years and 40.0 ml for those < 65 years, p < 0.001) with no additional matching performed. Our study accounted for other factors associated with prostate size and highlighted age as a significant determinant of these findings. In our study, we found that patients aged ≥ 65 years experienced better outcomes following Rezum than those receiving UroLift, whereas no age-related difference was observed in the UroLift group. We hypothesize that this could be attributed to a correlation between prostate tissue density and age. The UroLift device mechanically expands the prostatic urethral lumen, exerting minimal influence on tissue density. In contrast, Rezum uses thermal energy to necrotize prostate tissue, so tissue density could significantly affect the distance of thermal conduction. Unfortunately, there are no published studies specifically examining the relationship between prostate density (prostate weight/volume)—as distinct from PSA density—and age. However, King et al. reported in an animal study that thermal transition temperature increases with age, suggesting older tissue may facilitate more efficient thermal energy transfer. 16 Penne’s bioheat equation also demonstrates an inverse relationship between tissue density and specific heat, 17 and separate thermal conductivity measurements show that increasing tissue density reduces the distance of heat transfer. 18 Meanwhile, Matthew et al. found that aging leads to a decline in muscle quality, including density. 19 In this study, we excluded patients with prostate cancer to reduce the potential confounding effect of malignant tissue on our findings.. These findings suggest that older individuals with potentially lower-density tissue might help to explain the greater benefit from thermal-based interventions like Rezum that we observed in our data. Although TriNetX included a large number of patient records, the primary limitation of our study is the absence of prostate volume data. To minimize confounding in our results, we matched age, PSA, and BMI which are known to be correlated with prostate volume. Prior studies have consistently demonstrated a positive relationship between age and prostate size. 20 , 21 In large-scale studies involving 2,264 individuals with systemic BPH (Mochtar et al. 22 ), 2,270 patients with LUTS and biopsy-proven BPH (Hochberg et al. 23 ), and 4,627 men with BPH (Roehrborn et al. 24 ), serum PSA was consistently shown to be a reliable predictor of prostate volume.In addition to age and PSA, we matched BMI in our study, as multiple investigations—including Ken et al.’s 278-patient analysis 25 , a large Chinese observational study 26 , and Saurabh et al.’s prospective research 27 —consistently reported a positive correlation between BMI and prostate volume in men with BPH. Our findings suggest that patients aged ≥ 65 years demonstrated a lower reintervention rate after undergoing Rezum than Urolift. To the best of our knowledge, this is the first study to assess the associatio between patient age and the effectiveness of Rezum. Nevertheless, this study has several limitations. First, we lacked data on prostate volume despite our efforts to match age, PSA, and BMI as proxies. As a result, we cannot rule out the influence of individual prostate volume on our findings. Second, unlike other research, we did not include subjective measures such as the IPSS or uroflowmetry, preventing us from evaluating functional improvements across different procedures during follow-up. However, our primary outcome— reintervention rates—remained robust. Third, patients in UroLift group are three times larger than those in Rezum before matching. However, this may reflect real-world practice. Fourth, although we utilized TriNetX’s built-in PSM, some significant differences persisted in certain subgroup analyses. This may occur when initial disparities between cohorts are so pronounced that even after matching, the p-value remains below the 0.05 threshold—though higher than in the unmatched analysis and closer to the cutoff value. Conclusion In patients aged 65 or older, the Rezum procedure demonstrated a markedly lower reintervention rate over the three-year follow-up period; however, in those aged ≥ 40 to < 65, both procedures exhibited comparable reintervention rates, suggesting that age may be an influential factor in determining the relative benefits of Rezum.

Patients were excluded if they had a history of prostate cancer or had previously undergone prostate-related surgery\u0026mdash;such as UroLift, Rezum, TURP (52601), photoselective vaporization of the prostate (PVP) (52648), holmium laser enucleation of the prostate (HoLEP) (52649), transurethral needle ablation (TUNA) (53852), transurethral microwave thermotherapy (TUMT) (53850), transurethral incision of the prostate (TUIP) (52450), or waterjet ablation (0421T). In addition, patients who died during the three-year follow-up period were excluded. A total of 3,231 patients met the inclusion criteria, comprising 792 in the Rezum group (Cohort 1) and 2,439 in the UroLift group (Cohort 2). All patients were followed for three years, during which reintervention procedures were analyzed. Age, serum prostate-specific antigen (PSA) levels, and body mass index (BMI) were collected for the study population. For subgroup analysis, patients were categorized into two age groups: \u0026ge;40 to \u0026lt;\u0026thinsp;65 years and \u0026ge;\u0026thinsp;65 years older. One-to-one propensity score matching (PSM) was used to minimize potential confounding factors and avoid misleading conclusions.

We hypothesize that this could be attributed to a correlation between prostate tissue density and age. The UroLift device mechanically expands the prostatic urethral lumen, exerting minimal influence on tissue density. In contrast, Rezum uses thermal energy to necrotize prostate tissue, so tissue density could significantly affect the distance of thermal conduction. Unfortunately, there are no published studies specifically examining the relationship between prostate density (prostate weight/volume)\u0026mdash;as distinct from PSA density\u0026mdash;and age. However, King et al. reported in an animal study that thermal transition temperature increases with age, suggesting older tissue may facilitate more efficient thermal energy transfer.\u003csup\u003e\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e\u003c/sup\u003e Penne\u0026rsquo;s bioheat equation also demonstrates an inverse relationship between tissue density and specific heat,\u003csup\u003e\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e\u003c/sup\u003e and separate thermal conductivity measurements show that increasing tissue density reduces the distance of heat transfer.\u003csup\u003e\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e\u003c/sup\u003e Meanwhile, Matthew et al. found that aging leads to a decline in muscle quality, including density.\u003csup\u003e\u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e\u003c/sup\u003e In this study, we excluded patients with prostate cancer to reduce the potential confounding effect of malignant tissue on our findings..

To the best of our knowledge, this is the first study to assess the associatio between patient age and the effectiveness of Rezum. Nevertheless, this study has several limitations. First, we lacked data on prostate volume despite our efforts to match age, PSA, and BMI as proxies. As a result, we cannot rule out the influence of individual prostate volume on our findings. Second, unlike other research, we did not include subjective measures such as the IPSS or uroflowmetry, preventing us from evaluating functional improvements across different procedures during follow-up. However, our primary outcome\u0026mdash; reintervention rates\u0026mdash;remained robust. Third, patients in UroLift group are three times larger than those in Rezum before matching. However, this may reflect real-world practice. Fourth, although we utilized TriNetX\u0026rsquo;s built-in PSM, some significant differences persisted in certain subgroup analyses. This may occur when initial disparities between cohorts are so pronounced that even after matching, the p-value remains below the 0.05 threshold\u0026mdash;though higher than in the unmatched analysis and closer to the cutoff value.\u003c/p\u003e"},{"header":"Conclusion","content":"\u003cp\u003eIn patients aged 65 or older, the Rezum procedure demonstrated a markedly lower reintervention rate over the three-year follow-up period; however, in those aged\u0026thinsp;\u0026ge;\u0026thinsp;40 to \u0026lt;\u0026thinsp;65, both procedures exhibited comparable reintervention rates, suggesting that age may be an influential factor in determining the relative benefits of Rezum.\u003c/p\u003e"},{"header":"Declarations","content":"\u003ch2\u003eFunding:\u003c/h2\u003e\u003cp\u003eNo funding\u003c/p\u003e\u003ch2\u003eAuthor Contribution\u003c/h2\u003e\u003cp\u003eYC Lu: Project development, Manuscript writingW Chiu: Manuscript revisedCH Ho: Data CollectionYH Shao: Project development, Manuscript revised\u003c/p\u003e\u003ch2\u003eAcknowledgement\u003c/h2\u003e\u003cp\u003eThe authors have no conflict of interest and nothing to disclose.
