Effect of 3-Dimensional, Virtual Reality Models for Surgical Planning of Robotic Prostatectomy on Trifecta Outcomes: A Randomized Clinical Trial.

PURPOSE: Planning complex operations such as robotic-assisted radical prostatectomy requires surgeons to review 2-dimensional magnetic resonance imaging (MRI) cross-sectional images to understand 3-dimensional (3D), patient-specific anatomy. We sought to determine surgical outcomes for robotic-assisted radical prostatectomy when surgeons reviewed 3D, virtual reality (VR) models for operative planning. MATERIALS AND METHODS: A multicenter, randomized, single-blind clinical trial was conducted from January 2019 to December 2020. Patients undergoing robotic-assisted laparoscopic radical prostatectomy were prospectively enrolled and randomized to either a control group undergoing usual preoperative planning with prostate biopsy results and MRI only or to an intervention group where MRI and biopsy results were supplemented with a 3D VR model. The primary outcome measure was margin status, and secondary outcomes were oncologic control, sexual function and urinary function. RESULTS: Ninety-two patients were analyzed, with trends toward lower positive margin rates (33% vs 25%) in the intervention group, no significant difference in functional outcomes and no difference in traditional operative metrics (p >0.05). Detectable postoperative prostate specific antigen was significantly lower in the intervention group (31% vs 9%, p=0.036). In 32% of intervention cases, the surgeons modified their operative plan based on the model. When this subset was compared to the control group, there was a strong trend toward increased bilateral nerve sparing (78% vs 92%), and a significantly lower rate of postoperative detectable prostate specific antigen in the intervention subset (31% vs 0%, p=0.038). CONCLUSIONS: This randomized clinical trial demonstrated patients whose surgical planning involved 3D VR models have better oncologic outcomes while maintaining functional outcomes.

Evidence for the integration of total and free testosterone levels in the management of prostate cancer.

OBJECTIVE: To comprehensively assess total and calculated free testosterone levels in a consecutive group of patients with prostate cancer (PCa) and any potential impact on disease aggressiveness and recurrence outcomes. PARTICIPANTS AND METHODS: The study included a single-centre prospective cohort of 882 patients presenting for radical prostatectomy from 2009 to 2018. Data on total testosterone (TT), sex hormone-binding globulin (SHBG), and calculated free testosterone (cFT) were prospectively collected. Stepwise logistic regression models were used to assess correlations of TT and cFT with pathological Gleason Grade Group (GGG), extraprostatic extension (EPE), seminal vesicle invasion (SVI) and biochemical recurrence (BCR). RESULTS: Total testosterone remained nearly constant across decades (40s-80s): 0.09 decrease/year (R = 0.02), while SHBG increased 0.87/year (R = 0.32) and cFT decreased 0.08/year (R = -0.02). Low cFT of <5.5 independently predicted: very-high-risk GGG (odds ratio [OR] 0.435, 95% confidence interval [CI] 0.846-0.994; P = 0.036), EPE (OR 0.557, 95% CI 0.810-0.987; P = 0.011), SVI (OR 0.396, 95% CI 0.798-1.038; P = 0.059), and BCR within 1 year after robot-assisted radical prostatectomy (OR 0.638, 95% CI 0.971-3.512, P = 0.046). TT was not a predictor. CONCLUSION: In contrast to popular belief, testosterone remained stable in men aged 40-80 years, whereas free testosterone decreased by 2-3%/year. Low cFT was an independent predictor of very-high-risk PCa and BCR.

Management of patients who opt for radical prostatectomy during the coronavirus disease 2019 (COVID-19) pandemic: an international accelerated consensus statement.

OBJECTIVE: Coronavirus disease-19 (COVID-19) pandemic caused delays in definitive treatment of patients with prostate cancer. Beyond the immediate delay a backlog for future patients is expected. The objective of this work is to develop guidance on criteria for prioritisation of surgery and reconfiguring management pathways for patients with non-metastatic prostate cancer who opt for surgical treatment. A second aim was to identify the infection prevention and control (IPC) measures to achieve a low likelihood of coronavirus disease 2019 (COVID-19) hazard if radical prostatectomy (RP) was to be carried out during the outbreak and whilst the disease is endemic. METHODS: We conducted an accelerated consensus process and systematic review of the evidence on COVID-19 and reviewed international guidance on prostate cancer. These were presented to an international prostate cancer expert panel (n = 34) through an online meeting. The consensus process underwent three rounds of survey in total. Additions to the second- and third-round surveys were formulated based on the answers and comments from the previous rounds. The Consensus opinion was defined as ≥80% agreement and this was used to reconfigure the prostate cancer pathways. RESULTS: Evidence on the delayed management of patients with prostate cancer is scarce. There was 100% agreement that prostate cancer pathways should be reconfigured and measures developed to prevent nosocomial COVID-19 for patients treated surgically. Consensus was reached on prioritisation criteria of patients for surgery and management pathways for those who have delayed treatment. IPC measures to achieve a low likelihood of nosocomial COVID-19 were coined as 'COVID-19 cold' sites. CONCLUSION: Reconfiguring management pathways for patients with prostate cancer is recommended if significant delay (>3-6 months) in surgical management is unavoidable. The mapped pathways provide guidance for such patients. The IPC processes proposed provide a framework for providing RP within an environment with low COVID-19 risk during the outbreak or when the disease remains endemic. The broader concepts could be adapted to other indications beyond prostate cancer surgery.

Impact of statin use on overall and time to biochemical failure following radical prostatectomy or radiation therapy.

OBJECTIVES: To assess the impact of statin use on overall and time to biochemical failure following primary treatment of localized prostate cancer (PCa). SUBJECTS/PATIENTS AND METHODS: 1581 patients undergoing radical prostatectomy (RP) or radiation therapy (RT) for primary treatment of PCa between July 2007 and January 2020 were evaluated for statin use, demographic/oncologic characteristics, and biochemical outcomes. Rate of biochemical failure (BF) was assessed overall and at 1, 3, and 5 years; time to BF was estimated with Kaplan-Meier. Logistic and linear regression were used to control for treatment modality and disease characteristics. RESULTS: The average age was 63.0 ± 7.5 years and median pre-treatment PSA was 6.55 (IQR 4.94). 1473 (93.2%) and 108 (6.8%) underwent RP and RT, respectively. RP patients were younger, had lower pre-PSA, lower BMI, and lower risk disease. At 3.4 ± 2.7 years follow-up, 323 (20.4%) experienced BF. When stratified by statin use, BF overall and within 1, 3, and 5 years were not different. Time to BF, was lower in patients using statins (1.8 ± 1.9 years vs. 2.4 ± 2.6 years; p = 0.016). These results persisted in multivariate analysis, wherein statin use was not associated with BF but was associated with a shorter time to BF. CONCLUSION: Overall, statin use was not associated with a reduced risk of BF in RP or RT patients. However, for patients with BF, statin use was associated with a decreased time to BF. Future investigations are warranted to further elucidate the impact of statin use on PCa recurrence.

Testosterone replacement therapy reduces biochemical recurrence after radical prostatectomy.

OBJECTIVE: To evaluate risk of prostate cancer biochemical recurrence (BCR) after radical prostatectomy (RP) in men receiving vs not receiving testosterone replacement therapy (TRT). PATIENTS AND METHODS: A total of 850 patients underwent RP by a single surgeon. All patients had preoperative testosterone and sex hormone-binding globulin levels determined; free testosterone was calculated prospectively. In all, 152 (18%) patients with low preoperative calculated free testosterone (cFT) levels and delayed postoperative sexual function recovery were placed on TRT and proportionately matched to 419 control patients by pathological Gleason Grade Group (GGG) and stage. Rates and time to BCR [two consecutive prostate-specific antigen (PSA) levels of ≥0.2 ng/mL] were compared in univariate and multivariate regression; Cox regression was used to generate a survival function at the mean of covariates. RESULTS: The median follow-up was 3.5 years. There were no statistically significant differences in demographics or general health complications between groups. BCR occurred in 11/152 (7.2%) and 53/419 (12.6%) patients in the TRT and control groups, respectively. In adjusted time-to-event analysis, TRT was an independent predictor of recurrence-free survival. After accounting for GGG, pathological stage, preoperative PSA level, and cFT, patients on TRT were ~54% less likely to recur (hazard ratio 0.54, 95% confidence interval 0.292-0.997). In men destined to recur, TRT delayed time to recurrence by an average of 1.5 years. CONCLUSION: In our experience, TRT after RP significantly reduced BCR and delayed time to BCR. There was no identifiable general health complications associated with TRT. These findings are hypothesis-generating and require confirmation with multi-centred, prospective randomised controlled trials.

What Is a "Validated Questionnaire"? A Critical Review of Erectile Function Assessment.

BACKGROUND: In recent years, the assessment of erectile dysfunction (ED) has experienced a paradigm shift from objective, quantitative methods to subjective, qualitative patient-reported outcomes. Facilitated by this shift is the ongoing debate on questionnaire selection and need for standardization, particularly among sexual medicine specialists. AIM: To review current literature on assessment of erectile function via patient-reported outcomes and discuss the context, advantages, and limitations of currently available questionnaires. METHODS: A thorough literature search of erectile function questionnaires developed from 1990 through 2019 was carried out using 3 methods: a search of the MedLine databases; hand-search of peer-reviewed urologic, sexual medicine, and health policy journals; and expert review. The following keywords were used: [assessment of], [inventory], [questionnaire], or [validated measure]; in combination with: [sexual function] or [erectile function]. Measures were stratified into one of the following 3 groups: screening, outcome, or disease-specific. 3 screening measures (International Index of Erectile Function, the Male Sexual Health Questionnaire, and Brief Male Sexual Inventory); 5 outcome measures (Sexual Health Inventory for Men, Erection Hardness Score, Erectile Dysfunction Inventory for Treatment and Satisfaction, and Treatment Satisfaction Scale); and 3 categories of disease-specific measures (cancer, Peyronie's disease, and spinal cord injury) were included. OUTCOMES: Strengths, limitations, and valid uses of each erectile function questionnaire. RESULTS: There currently exists a wide variety of screening, outcome, and disease-specific measures for ED diagnosis, assessment, and treatment. Rigor of psychometric validation varies greatly across studies. However, depending on purpose of use, all abovementioned questionnaires have merit for use in clinical practice, are nonredundant, and can complement and supplement one another. CLINICAL IMPLICATIONS: Before choosing a specific measure for ED diagnosis, assessment, or treatment, there must be careful consideration of the questionnaire's psychometric properties, context of validation, and its possible limitations. STRENGTHS & LIMITATIONS: The patient reported outcome measures highlighted in this article complement and supplement one another, as each emphasizes a related yet distinct central theme. During selection for use in clinical practice and research studies, special attention needs to be paid to the context, strengths, and weaknesses of each measure. CONCLUSION: When used conscientiously, patient-reported questionnaires can significantly optimize patient management. Yafi FA, Huynh LM, Ahlering T, et al. What Is a "Validated Questionnaire"?

Correction to: Unintended consequences of decreased PSA-based prostate cancer screening.

In the original publication, part of funding information was missed.

Unintended consequences of decreased PSA-based prostate cancer screening.

BACKGROUND: In May 2012, the US Preventive Services Task Force issued a grade D recommendation against PSA-based prostate cancer screening. Epidemiologists have concerns that an unintended consequence is a problematic increase in high-risk disease and subsequent prostate cancer-specific mortality. MATERIALS AND METHODS: To assess the effect of decreased PSA screening on the presentation of high-risk prostate cancer post-radical prostatectomy (RP). Nine high-volume referral centers throughout the United States (n = 19,602) from October 2008 through September 2016 were assessed and absolute number of men presenting with GS ≥ 8, seminal vesicle and lymph node invasion were compared with propensity score matching. RESULTS: Compared to the 4-year average pre-(Oct. 2008-Sept. 2012) versus post-(Oct. 2012-Sept. 2016) recommendation, a 22.6% reduction in surgical volume and increases in median PSA (5.1-5.8 ng/mL) and mean age (60.8-62.0 years) were observed. The proportion of low-grade GS 3 + 3 cancers decreased significantly (30.2-17.1%) while high-grade GS 8 + cancers increased (8.4-13.5%). There was a 24% increase in absolute numbers of GS 8+ cancers. One-year biochemical recurrence rose from 6.2 to 17.5%. To discern whether increases in high-risk disease were due to referral patterns, propensity score matching was performed. Forest plots of odds ratios adjusted for age and PSA showed significant increases in pathologic stage, grade, and lymph node involvement. CONCLUSIONS: All centers experienced consistent decreases of low-grade disease and absolute increases in intermediate and high-risk cancer. For any given age and PSA, propensity matching demonstrates more aggressive disease in the post-recommendation era.

Predictive modelling of 2-year potency outcomes using a novel 90-day erection fullness scale after robot-assisted radical prostatectomy.

OBJECTIVE: To introduce a patient-reported erection fullness scale (%fullness) after robot-assisted radical prostatectomy (RARP) as a qualitative adjunct to the five-item version of the International Index of Erectile Function (IIEF-5) and as a 90-day predictor of 2-year potency outcomes. PATIENTS AND METHODS: Prospective data were collected from 540 men with preoperative IIEF-5 scores of 22-25 who underwent RARP by a single surgeon, and of whom 299 had complete data at all time points up to 2 years. In addition to standard assessment tools (IIEF-5 and erections sufficient for intercourse [ESI]), the men were asked to 'indicate the fullness you are able to achieve in erections compared to before surgery?' (range: 0-100%). The primary outcome was prediction of potency (defined as ESI) at 24 months, based on 90-day %fullness tertile (0-24%, 25-74% and 75-100%). RESULTS: A total of 299 men with complete follow-up were included in the study. Significant predictors of 24-month potency included age, body mass index, pathological stage, nerve-sparing status and %fullness tertiles. When the men (preoperative IIEF-5 score 22-25) were assessed at 90 days after RARP, 181/299 (61%) had erections inadequate for intercourse. If IIEF-5 scores of 1-6 were used, 142/181 men (78%) would be targeted for early intervention. By contrast, if 0-24% fullness was used, 88/181 men (49%) would be targeted. If both the IIEF-5 score and %fullness were used, this would be reduced to 77/181 men (43%). CONCLUSIONS: We introduce %fullness as a qualitative adjunct to the IIEF-5 score, and separately as a 90-day predictor of 2-year potency recovery. This initial report is hypothesis-generating, such that the use of %fullness enables the identification of men who are most likely to benefit from early, secondary intervention.

Limitations of the National Comprehensive Cancer Network® (NCCN®) Guidelines for Prediction of Limited Life Expectancy in Men with Prostate Cancer.

PURPOSE: National Comprehensive Cancer Network prostate cancer guidelines for the prediction of life expectancy recommend subtracting 50% of life table predicted longevity for those in the lowest quartile of health. However, it is unclear how to identify these men and if their survival is uniform. MATERIALS AND METHODS: We sampled records of 1,482 men diagnosed with prostate cancer from 1998 to 2004 at 2 VA hospitals. We identified men in the lowest quartile of health by age using Charlson scores, calculated their NCCN predicted life expectancy, and compared this with observed median survival in aggregate and across comorbidity subgroups. RESULTS: Men with Charlson scores of 2+ (age less than 75 years) and 3+ (age 75 years or older) comprised the lowest quartile of health. Among those younger than 65, 65 to 69, 70 to 74, 75 to 79 and 80 years or older, observed survival vs NCCN predicted life expectancy in years was similar at 10.4 vs 11.1, 10.0 vs 7.8, 6.2 vs 6.4, 4.4 vs 4.9 and 3.7 vs 3.3, respectively. Yet within the lowest quartile there was significant heterogeneity in survival among men with differing Charlson scores. For example, men age 65 to 69 years with Charlson scores 2, 3 and 4+ had an observed median survival greater than 13.3, 9.4 and 4.3 years, respectively. NCCN guidelines misclassified 10-year life expectancy in 24% and 56% of men age less than 65 and 65 to 69 years, and 5-year life expectancy in 18% of men age 70 to 74 years. CONCLUSIONS: While NCCN predictions matched observed survival on average for the lowest quartile of health, there was substantial heterogeneity in survival by Charlson scores. More granular assessments of life expectancy should be used for those at highest risk for mortality.

The importance of surgical margins in prostate cancer.

Positive surgical margins (PSM) after radical prostatectomy (RP) are a predictor of biochemical recurrence (BCR), and highly dependent on surgeon, experience, and skill. The length and location PSMs are important, with significant differences between open and robotic RP. The impact of PSMs on BCR remains secondary to other clinico-pathologic variables: Gleason Score, pathologic stage, and baseline PSA. However, lower PSM rates are associated with reduced use of secondary interventions and patient anxiety of cancer recurrence.

A randomized, double-blind, solifenacin succinate versus placebo control, phase 4, multicenter study evaluating urinary continence after robotic assisted radical prostatectomy.

PURPOSE: Bladder dysfunction influences recovery of urinary continence after radical prostatectomy. We performed a multicenter, randomized, double-blind study evaluating solifenacin vs placebo on return to continence in patients who were still incontinent 7 to 21 days after catheter removal after robot-assisted radical prostatectomy. MATERIALS AND METHODS: A wireless personal digital assistant was given to patients the day of catheter removal. Encrypted answers were transmitted daily to dedicated servers. After a 7 to 21-day treatment-free washout period, patients requiring 2 to 10 pads per day for 7 consecutive days were randomized (1:1) to 5 mg solifenacin daily or placebo. The primary end point was time from first dose to continence defined as 0 pads per day or a dry security pad for 3 consecutive days. Secondary end points included proportion of patients continent at end of study, average change in pads per day number and quality of life assessments. RESULTS: A total of 1,086 screened patients recorded personal digital assistant information. Overall 640 patients were randomized to solifenacin vs placebo and 17 failed to take medication. There was no difference in time to continence (p=0.17). Continence was achieved by study end in 91 of 313 (29%) vs 66 of 309 (21%), respectively (p=0.04). Pads per day change from baseline was -3.2 and -2.9, respectively (p=0.03). Dry mouth was the only common adverse event seen in 6.1% and 0.6%, respectively. Constipation rates were similar. The overall rate of continence in the entire population from screening to end of study was 73%. CONCLUSIONS: There was no effect on primary outcome but some secondary end points benefited the solifenacin arm. The study provides level 1B clinical evidence for continence outcomes after robot-assisted radical prostatectomy.

Development of a standardised training curriculum for robotic surgery: a consensus statement from an international multidisciplinary group of experts.

OBJECTIVES: To explore the views of experts about the development and validation of a robotic surgery training curriculum, and how this should be implemented. MATERIALS AND METHODS: An international expert panel was invited to a structured session for discussion. The study was of a mixed design, including qualitative and quantitative components based on focus group interviews during the European Association of Urology (EAU) Robotic Urology Section (ERUS) (2012), EAU (2013) and ERUS (2013) meetings. After introduction to the aims, principles and current status of the curriculum development, group responses were elicited. After content analysis of recorded interviews generated themes were discussed at the second meeting, where consensus was achieved on each theme. This discussion also underwent content analysis, and was used to draft a curriculum proposal. At the third meeting, a quantitative questionnaire about this curriculum was disseminated to attendees to assess the level of agreement with the key points. RESULTS: In all, 150 min (19 pages) of the focus group discussion was transcribed (21 316 words). Themes were agreed by two raters (median agreement κ 0.89) and they included: need for a training curriculum (inter-rater agreement κ 0.85); identification of learning needs (κ 0.83); development of the curriculum contents (κ 0.81); an overview of available curricula (κ 0.79); settings for robotic surgery training ((κ 0.89); assessment and training of trainers (κ 0.92); requirements for certification and patient safety (κ 0.83); and need for a universally standardised curriculum (κ 0.78). A training curriculum was proposed based on the above discussions. CONCLUSION: This group proposes a multi-step curriculum for robotic training. Studies are in process to validate the effectiveness of the curriculum and to assess transfer of skills to the operating room.

Oncologic outcomes in men with metastasis to the prostatic anterior fat pad lymph nodes: a multi-institution international study.

BACKGROUND: The presence of lymph nodes (LN) within the prostatic anterior fat pad (PAFP) has been reported in several recent reports. These PAFP LNs rarely harbor metastatic disease, and the characteristics of patients with PAFP LN metastasis are not well-described in the literature. Our previous study suggested that metastatic disease to the PAFP LN was associated with less severe oncologic outcomes than those that involve the pelvic lymph node (PLN). Therefore, the objective of this study is to assess the oncologic outcome of prostate cancer (PCa) patients with PAFP LN metastasis in a larger patient population. METHODS: Data were analyzed on 8800 patients from eleven international centers in three countries. Eighty-eight patients were found to have metastatic disease to the PAFP LNs (PAFP+) and 206 men had isolated metastasis to the pelvic LNs (PLN+). Clinicopathologic features were compared using ANOVA and Chi square tests. The Kaplan-Meier method was used to calculate the time to biochemical recurrence (BCR). RESULTS: Of the eighty-eight patients with PAFP LN metastasis, sixty-three (71.6%) were up-staged based on the pathologic analysis of PAFP and eight (9.1%) had a low-risk disease. Patients with LNs present in the PAFP had a higher incidence of biopsy Gleason score (GS) 8-10, pathologic N1 disease, and positive surgical margin in prostatectomy specimens than those with no LNs detected in the PAFP. Men who were PAFP+ with or without PLN involvement had more aggressive pathologic features than those with PLN disease only. However, there was no significant difference in BCR-free survival regardless of adjuvant therapy. In 300 patients who underwent PAFP LN mapping, 65 LNs were detected. It was also found that 44 out of 65 (67.7%) nodes were located in the middle portion of the PAFP. CONCLUSIONS: There was no significant difference in the rate of BCR between the PAFP LN+ and PLN+ groups. The PAFP likely represents a landing zone that is different from the PLNs for PCa metastasis. Therefore, the removal and pathologic analysis of PAFP should be adopted as a standard procedure in all patients undergoing radical prostatectomy.

Fluoroquinolone resistant rectal colonization predicts risk of infectious complications after transrectal prostate biopsy.

PURPOSE: Infection after transrectal prostate biopsy has become an increasing concern due to fluoroquinolone resistant bacteria. We determined whether colonization identified by rectal culture can identify men at high risk for post-transrectal prostate biopsy infection. MATERIALS AND METHODS: Six institutions provided retrospective data through a standardized, web based data entry form on patients undergoing transrectal prostate biopsy who had rectal culture performed. The primary outcome was any post-transrectal prostate biopsy infection and the secondary outcome was hospital admission 30 days after transrectal prostate biopsy. We used chi-square and logistic regression statistical analysis. RESULTS: A total of 2,673 men underwent rectal culture before transrectal prostate biopsy from January 1, 2007 to September 12, 2013. The prevalence of fluoroquinolone resistance was 20.5% (549 of 2,673). Fluoroquinolone resistant positive rectal cultures were associated with post-biopsy infection (6.6% vs 1.6%, p <0.001) and hospitalization (4.4% vs 0.9%, p <0.001). Fluoroquinolone resistant positive rectal culture increased the risk of infection (OR 3.98, 95% CI 2.37-6.71, p <0.001) and subsequent hospital admission (OR 4.77, 95% CI 2.50-9.10, p <0.001). If men only received fluoroquinolone prophylaxis, the infection and hospitalization proportion increased to 8.2% (28 of 343) and 6.1% (21 of 343), with OR 4.77 (95% CI 2.50-9.10, p <0.001) and 5.67 (95% CI 3.00-10.90, p <0.001), respectively. The most common fluoroquinolone resistant bacteria isolates were Escherichia coli (83.7%). Limitations include the retrospective study design, nonstandardized culture and interpretation of resistance methods. CONCLUSIONS: Colonization of fluoroquinolone resistant organisms in the rectum identifies men at high risk for infection and subsequent hospitalization from prostate biopsy, especially in those with fluoroquinolone prophylaxis only.

The Melbourne Consensus Statement on the early detection of prostate cancer.

Various conflicting guidelines and recommendations about prostate cancer screening and early detection have left both clinicians and their patients quite confused. At the Prostate Cancer World Congress held in Melbourne in August 2013, a multidisciplinary group of the world's leading experts in this area gathered together and generated this set of consensus statements to bring some clarity to this confusion. The five consensus statements provide clear guidance for clinicians counselling their patients about the early detection of prostate cancer.

Assessing Decision Regret in Patients with Same-Day Discharge Pathway After Robot-Assisted Radical Prostatectomy.

Introduction: After the introduction of same-day discharge (SDD) pathways for various surgeries, these pathways have demonstrated comparable complication rates and a reduced overall cost of care. Outpatient robot-assisted radical prostatectomy (RARP) is introduced in high-volume centers; however, patients' perspectives on the SDD RARP protocol are not well understood. Materials and Methods: A questionnaire consisting of 24 questions, including the Likert Decisional Regret Scale, was distributed to patients who underwent RARP at our center. The overall decision regret score was calculated as described in the literature. We used 15 as a cutoff point for differentiating between high- and low-regret rates. Median and interquartile range were determined for non-normally distributed variables, while mean ± standard deviation was calculated for continuous data. Results: Of the 72 patients who completed the questionnaire, 65.7% (n = 44) of patients felt no regret about their decision of choosing the SDD RARP protocol and 90.3% (n = 65) of men stated that they would have made the same decision. At the same time, 97.1% (n = 68) of patients would also recommend this procedure to others. The median decisional regret score of the cohort (n = 67) was 0 (0-10). Fifty-four of 67 (80.6%) patients were in the low-regret score group, while 13 (19.4%) were in the high-regret group. Patients in the high-regret group were more likely to have low household income (<$30,000 a year) and they experienced postoperative pain more frequently compared with patients in the lower regret group (7.7% vs 1.9%, p = 0.626, and 61.5% vs 38.9%, p = 0.212, respectively). Conclusions: Most patients expressed low regret about choosing the SDD pathway for RARP, underscoring the importance of thorough explanation of the procedure and discharge process to enhance patient experience. However, a subset of patients did express regret, possibly due to an interplay of patient- and procedure-related factors.

Detailed analysis of patients with metastasis to the prostatic anterior fat pad lymph nodes: a multi-institutional study.

PURPOSE: Lymph nodes in the prostatic anterior fat pad rarely harbor metastatic disease. Therefore, the characteristics of patients with prostatic anterior fat pad lymph node metastasis are not well described in the literature. We identified the perioperative characteristics and assessed the clinical outcomes of patients with prostatic anterior fat pad lymph node metastasis. MATERIALS AND METHODS: At 8 tertiary care centers a total of 4,261 patients underwent complete removal and pathological analysis of the prostatic anterior fat pad. We describe preoperative and pathological characteristics, and clinical management and outcomes in patients with metastatic disease to the prostatic anterior fat pad. RESULTS: Metastatic disease to the prostatic anterior fat pad lymph nodes was detected in 40 patients (0.94%), of whom 37 (92.5%) had intermediate or high risk features preoperatively. Most patients with prostatic anterior fat pad metastases underwent concomitant pelvic lymph node dissection, and adjuvant therapy with radiation, androgen ablation and/or chemotherapy. A total of 27 patients (67.5%) with prostatic anterior fat pad metastatic disease were up-staged as a result of prostatic anterior fat pad pathological analysis, of whom 14 (51.8%) remained free of biochemical recurrence with observation and/or definitive adjuvant/salvage therapy. CONCLUSIONS: Most patients with prostatic anterior fat pad metastatic disease had intermediate to high risk features preoperatively. In some patients with such lymph node metastasis removing these lymph nodes resulted in prolonged biochemical recurrence-free survival. Therefore, we recommend that the prostatic anterior fat pad be removed in all patients undergoing radical prostatectomy. However, pathological analysis of the prostatic anterior fat pad may be limited to patients with intermediate to high risk oncological features preoperatively.

Preserving continence during robotic prostatectomy.

Preservation of postoperative urinary continence remains the primary concern of all men and their surgeons following robot-assisted radical prostatectomy (RARP). Without doubt, continence is the most important quality of life issue following radical prostatectomy. Identification of difficulties and lessons learned over time has helped focus efforts in order to improve urinary quality of life and continence. This review will examine definitions of continence and urinary quality of life evaluation, technical aspects and the impact of patient-related factors affecting time to and overall continence.

Climacturia and Penile Length Shortening: Adverse Outcomes following Robot-Assisted Radical Prostatectomy.

Purpose: While erectile dysfunction and urinary incontinence are commonly cited side effects following radical prostatectomy (RP), climacturia and penile length shortening are less explored. The present study seeks to explore the incidence, risk factors, and predictors of recovery associated with climacturia and penile length shortening following robot-assisted radical prostatectomy (RARP). Patients and Methods: From September 2018 to January 2020, 800 patients underwent RARP for primary treatment of localized prostate cancer. A survey was sent to patients following 1-year follow-up assessing outcomes of continence, erectile dysfunction, climacturia, and penile length shortening. Descriptive statistics were utilized to describe incidence and risk factors and logistic regression modeling was used to identify predictors associated with recovery. Results: Of the 800 patients surveyed, 339 (42%) and 369 (46%) patients responded, with 127/339 (37.5%) and 216/369 (58.5%) endorsing climacturia and penile length shortening. In univariate analysis, a lack of bilateral nerve sparing was associated with climacturia; high body mass index (BMI), high prostate weight, lack of nerve-sparing, and high pathologic stage was associated with penile length shortening. In logistic regression modeling, BMI, prostate weight, and p-stage were all significantly correlated with penile length shortening. Recovery from climacturia was associated with a preoperative International Index of Erectile Function-5 score >21.
