Predictors of Same-day Discharge After Single-Port Transvesical Enucleation of the Prostate.

OBJECTIVE: To determine the rate of outpatient cases and identify predictors for same-day discharge (SDD) after single-port transvesical enucleation of the prostate (STEP). METHODS: Retrospective analysis of all consecutive STEP cases performed at a single center by 3 surgeons from February 2019 to October 2023. The cohort was categorized into SDD cases (<8 hours until discharge) and inpatient cases. Group comparisons were made and logistic regression was used to identify predictors of SDD. RESULTS: A total of 152 STEP cases were performed successfully without additional ports or conversions. Fifty-two patients were pre-planned admissions, leaving 100 planned outpatient cases, of which 86% were discharged on the same day (median length of stay of 4.7 hours). Comparing the groups, inpatient cases were older, had higher Charlson Comorbidity Index (CCI) scores, higher estimated blood loss (EBL) during surgery, and more intraoperative complications than SDD patients. Univariate logistic regression identified age and CCI as the predictors associated with SDD after STEP. Notably, there were no major postoperative complications or readmissions in either group. CONCLUSION: In our 4-year experience with STEP, lower age and CCI score were significant predictors of SDD. The comprehensive evaluation criteria for discharge foster a safe recovery at home, coupled with a 0% rate of major postoperative complications and readmissions. These findings underscore the safety and efficacy of STEP, guiding patient counseling and surgeon expectations.

Single Port Robotic Kidney Autotransplantation: Initial Case Series and Description of Technique.

PURPOSE: Minimally invasive kidney autotransplantation (KAT) has demonstrated reduced morbidity, however multiport robotic approach required patient repositioning and multiple sets of incisions. We present our initial series of single-port (SP) robotic KAT, ideal for multi-quadrant surgeries, and aim to evaluate feasibility and safety of the novel approach. METHODS: Between 2018 and 2022, 8 consecutive patients underwent SP KAT using the DaVinci SP platform. Patient clinicopathologic variables and perioperative outcomes were recorded. Indications for KAT include complex or recurrent ureteral stricture, ureteral avulsion, and chronic visceral pain due to multiple etiologies. RESULTS: All SP KATs were successfully performed without repositioning or conversion to open. Operative times ranged from 366 to 701 minutes, warm and cold ischemia times between 4 to 10 minutes and 86 to 209 minutes, respectively. Median hospital length of stay was 3 days. At a median of 13 months follow-up, latest postoperative GFRs were stable, ranging from +23% to -10%. There were no complications. CONCLUSION: We demonstrate our single port, multiquadrant robotic kidney auto transplantation technique performed though a single incision further reducing surgical morbidity. All cases were completed successfully without conversion or loss of graft function. All patients reported resolution of flank pain and no radiological evidence of urinary obstruction on follow up.

Longitudinal analysis of YouTube videos discussing post-prostatectomy erectile dysfunction.

BACKGROUND: YouTube is heavily utilized by patients as an educational resource, but this content can be fraught with misinformation. We sought to characterize the quality of videos on YouTube discussing postprostatectomy erectile dysfunction and to evaluate metrics associated with retaining a top position in search results over time. METHODS: In October 2019, we watched the first 100 YouTube videos using the search query "radical prostatectomy erectile dysfunction." Videos not relevant to the topic were excluded. Video metrics were collected, and content quality was evaluated using the DISCERN instrument. In June 2022, the search was repeated and video metrics were updated. Video characteristics were associated with search rank and the ability to remain in the top 100 spots using the Pearson correlation coefficient (r) and logistic regression, respectively. RESULTS: We included 81 videos which amassed 529,428 views in 2019. The median total DISCERN score was 29 (IQR 21-42), which is interpreted as a poor quality video. Self-promotion or commercial bias was present in 42 videos (51.9%); false claims were present in 16 (19.8%). There was no correlation between DISCERN score and search rank (r = 0.08, p = 0.49). In 2022, 15 videos remained in the top 100 search results and had a higher median DISCERN score than videos no longer in the top 100 (46 vs. 28.5, p = 0.01). Each additional DISCERN point was associated with a 7% higher odds of remaining in the top 100 (OR 1.07, 95% CI 1.01-1.11, p = 0.003). CONCLUSIONS: The quality of the top 100 YouTube videos discussing postprostatectomy erectile dysfunction is low. Higher quality videos had a higher odds of remaining in the top 100 search results over time but do not correlate with the order in which they are ranked.

Minimally-Invasive Radical Nephrectomy and Left-Sided Level II Caval Thrombectomy: A New Combined Technique.

OBJECTIVE: To present a combined multiport robotic and open approach for left radical nephrectomy and inferior vena cava thrombectomy in patients with a primary left renal mass and level II inferior vena cava (IVC) tumor thrombus. METHODS: A 69-year-old female was diagnosed with an 8.9cm left renal neoplasm with level II IVC thrombus. She was placed in the left-side-up flank position. The descending colon was mobilized and the left gonadal vein was identified. The left renal vein was identified and fully dissected. The left renal artery was dissected and stapled. The kidney was dissected and left detached with exception of the renal vein. The robot was undocked and the patient was positioned supine. Through a supra-umbilical midline incision, the ascending colon and duodenum were mobilized medially. The right renal vein and IVC were identified and dissected to the level of hepatic veins. The IVC was clamped using a Satinsky clamp. The right renal artery and vein remained patent during thrombectomy. The IVC was opened, the thrombus was evacuated, and IVC was closed. Clamps were removed and the kidney was removed. RESULTS: Operative time was 405 minutes. IVC clamp time was 14 minutes. Estimated blood loss was 500cc. Recovery was uncomplicated. Length of stay was 4 days. Pathology showed clear cell carcinoma with negative margins. CONCLUSION: IVC thrombectomy is challenging on left sided tumors. Combining a robotic and open technique together is feasible and allows a smaller supra-umbilical midline incision compared to standard open incision.

Long-term comparative outcomes of partial nephrectomy and cryoablation in patients with solitary kidneys: a single-center analysis.

BACKGROUND: Patients with solitary kidneys are amenable to postoperative acute kidney injury (AKI) after PN. We compared the functional and oncological outcomes of cryoablation (CA) and PN in patients with a solitary kidney and a cT1a renal mass. METHODS: From a single-institution series, we analyzed 74 patients (31 PN, 43 CA) with a solitary kidney who underwent treatment for a cT1a renal mass. The functional outcomes were AKI and estimated glomerular filtration rate (eGFR) preservation. Oncological outcomes were recurrence and death. Linear mixed-effects and logistic regression models were used for functional outcomes analysis, whereas oncological outcomes were analyzed using the Kaplan-Meier method. RESULTS: Median follow-up was 63.9 months. PN group had lower median age (59 years vs. 68, P<0.001) and larger median tumor size (2.80 cm vs. 2.0, p =0.003). AKI was more common in the PN group on postoperative day 1 (58% vs. 2.8%, P<0.001). However, only one patient in the PN group required temporary dialysis in the perioperative period. eGFR preservation was similar at postoperative 3 months (89% vs. 90%, P=0.083), or 12 months (85% vs. 94%, P=0.2) follow-up. CA group had higher recurrence rate (29% vs. 3.2%, P=0.005), and worse recurrence-free survival (P=0.027). Overall survival (OS) was comparable (P=0.31). CONCLUSIONS: In a solitary kidney setting, CA is associated with a lower risk of AKI at postoperative day 1 compared to PN. Functional outcome is comparable upon longer follow-up. The local recurrence rates are significantly higher in the CA group with no significant difference in OS.

Using Competing Risk of Mortality to Inform the Transition from Prostate Cancer Active Surveillance to Watchful Waiting.

BACKGROUND: For men on active surveillance (AS) for prostate cancer (PCa), disease progression and age-related changes in health may influence decisions about pursuing curative treatment. OBJECTIVE: To evaluate the predicted PCa and non-PCa mortality at the time of reclassification among men on AS, to identify clinical criteria for considering a transition from AS to watchful waiting (WW). DESIGN, SETTING, AND PARTICIPANTS: Patients enrolled in a large AS program who experienced biopsy grade reclassification (Gleason grade increase) were retrospectively examined. All patients who had complete documentation of medical comorbidities at reclassification were included. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A validated model was used to assess 10- and 15-yr untreated PCa and non-PCa mortalities based on patient comorbidities and PCa clinical characteristics. We compared the ratio of predicted PCa mortality with predicted non-PCa mortality ("predicted mortality ratio") and divided patients into four risk tiers based on this ratio: (1) tier 1 (ratio: >0.33), (2) tier 2 (ratio 0.33-0.20), (3) tier 3 (ratio 0.20-0.10), and (4) tier 4 (ratio <0.10). RESULTS AND LIMITATIONS: Of the 344 men who were reclassified, 98 (28%) were in risk tier 1, 85 (25%) in tier 2, 93 (27%) in tier 3, and 68 (20%) in tier 4 for 10-yr mortality. Fifteen-year risk tiers were distributed similarly. The 23 (6.7%) men who met the "transition triad" (age >75 yr, Charlson Comorbidity Index >3, and grade group ≤2) had a 14-fold higher non-PCa mortality risk and a lower predicted mortality ratio than those who did not (0.07 vs 0.23, p < 0.001). The primary limitations of our study included its retrospective nature and the use of predicted mortalities. CONCLUSIONS: At reclassification, nearly half of patients had a more than five-fold and one in five patients had a more than ten-fold higher risk of non-PCa death than patients having a risk of untreated PCa death. Despite a more significant cancer diagnosis, a transition to WW for older men with multiple comorbidities and grade group <3 PCa should be considered. PATIENT SUMMARY: Men with favorable-risk prostate cancer and life expectancy of >10 yr are often enrolled in active surveillance, which entails delay of curative treatment until there is evidence of more aggressive disease. We examined a group of men on active surveillance who developed more aggressive disease, and found, nevertheless, that the majority of these men continued to have a dramatically higher risk of death from non-prostate cancer causes than from prostate cancer based on a risk prediction tool. For men older than 75 yr, who have multiple medical conditions and who do not have higher-grade cancer, it may be reasonable to reconsider the need for curative treatment given the low risk of death from prostate cancer compared with the risk of death from other causes.

Single Port Transvesical Robotic Radical Prostatectomy: Initial Clinical Experience and Description of Technique.

OBJECTIVE: To describe our surgical technique and early results for the single port (SP) transvesical robotic radical prostatectomy using the da Vinci SP surgical system. PATIENTS & METHODS: Twenty patients underwent SP radical prostatectomy through a transvesical approach. Through a 3 cm suprapubic incision, the bladder was incised and a GelPOINT mini system was used for floating docking. Through the gel port, the dedicated SP robotic port, a 12 mm assistant port, and a flexible suction tubing were introduced. RESULTS: All cases were completed successfully without need for extra ports or conversion. No intraoperative complications were recorded. Median (IQR) total robotic time was 119 (99-127) minutes. Median (IQR) estimated blood loss was 135 (100-162) mL. Median (IQR) hospital length of stay was 4.4 (3.9-22.2) hours. None of the patients required opioids use after discharge. Median (IQR) time with a Foley catheter after surgery was 4 (4-6) days and 75% of the patients had immediate continence within 48 hours after Foley catheter removal. 85% were totally continent within 10 days after catheter removal. Three patients (15%) had positive surgical margins (all focal) on pathology. Two patients had transvesical lymph node dissection with 4 and 15 lymph nodes negative on final pathology. CONCLUSION: We demonstrated the feasibility of SP robotic transvesical radical prostatectomy and pelvic lymph node dissection using a dedicated SP robotic platform. Favorable perioperative outcomes were seen, along with low complication rate, same day discharge, elimination of opioid requirement, and high rate of immediate recovery of continence as well as a low positive margin rate.

Testicular ultrasound underestimates the size of small testicular masses: a radiologic-pathologic correlation study.

PURPOSE: Increasing use and resolution of testicular ultrasound imaging has resulted in a greater diagnosis of non-palpable small testicular masses and subsequent over-treatment with orchiectomy. Our aim was to determine the diagnostic accuracy of testicular ultrasound to accurately determine the pathologic size of small testicular masses (SMTMs) and to evaluate the association of various measurements with benign pathology. METHODS: Retrospectively, an institutional testicular cancer database was reviewed to evaluate the patients who underwent an orchiectomy for a testicular mass seen on ultrasound from 2003 to 2017. Three-dimensional measurements were compared from the ultrasound and pathology specimens, including other measures such as tumor volume and percentage of testicular volume. Finally, the predictive accuracy of maximum diameter and tumor volume to predict benign pathology was evaluated using receiver-operating curve analysis. RESULTS: We identified 208 patients and showed that ultrasound significantly underestimated sub-centimeter testicular masses (mean difference 0.56 cm, 95%CI 0.89-0.14, p = 0.004) and testicular masses between 1 and < 2 cm (mean difference 0.50 cm, 95%CI 0.97-0.15, p = 0.009). Tumor volume measured on ultrasound was consistently similar to pathologic tumor volume across all sizes and was significantly correlated (Spearman's Rho = 0.81). Mass volume had a greater predictive accuracy for benign pathology than maximum diameter using a 1 cm cut-off (AUC 0.65 vs 0.60). CONCLUSION: Using the maximal diameter, testicular ultrasound significantly miscalculated the pathologic dimensions of masses less than 2 cm compared to orchiectomy specimens. Volumetric measurements may better represent actual tumor sizes for SMTMs and may be a more useful measure for identifying those a higher risk for benign pathology, however, further studies are required.

Effect of Erythropoietin on Erectile Function after Radical Prostatectomy: The ERECT Randomized Clinical Trial.

PURPOSE: Erectile dysfunction significantly impacts quality of life for men undergoing radical prostatectomy for prostate cancer. Erythropoietin is a promising neurotrophic factor for neurogenic erectile dysfunction based on preclinical and retrospective data. MATERIALS AND METHODS: ERECT (NCT00737893) is a phase 2, double-blinded, randomized, placebo-controlled trial (July 2017-December 2019) evaluating the impact of perioperative erythropoietin on recovery of erectile function and other patient-reported, health-related quality of life outcomes after bilateral nerve-sparing radical prostatectomy (3, 6, 9, and 12 months). Erythropoietin (20,000 units) or saline placebo was injected subcutaneously the day before, day of, and day after surgery for 3 total doses. RESULTS: Of 63 patients assessed for eligibility, 56 patients were randomized. Arms (29 erythropoietin, 27 placebo) were well balanced (89.3% robotic, median age 55.5 years). International Index of Erectile Function-Erectile Function Domain (IIEF-EF) scores increased from median 12.5 at 3 months to 24.5 at 12 months. Median 2-week serum hemoglobin was higher for the erythropoietin arm compared to placebo (14.7 vs 13.6, p=0.02). There was no statistically significant difference in IIEF-EF scores at 6 months comparing erythropoietin to placebo (p=0.50) or at other time points (mixed model regression coefficient: -1.7, 95% CI -6.1-2.7, p=0.45). Excellent nerve-sparing rating (10/10) was associated with improved IIEF-EF recovery (+5.2, p=0.022). Other patient-reported, health-related quality of life domains as well as oncologic outcome and complications were similar between arms during followup. CONCLUSIONS: In the context of brief perioperative dosing, erythropoietin did not improve recovery of erectile function for men undergoing radical prostatectomy for prostate cancer compared to placebo. Further research to identify effective adjuncts to improve health-related quality of life for these men is needed.

Surgical ergonomics for urologists: a practical guide.

Poor ergonomics in the operating room can have detrimental effects on a surgeon's physical, psychological and economic well-being. This problem is of particular importance to urologists who are trained in nearly all operative approaches (open, laparoscopic, robotic-assisted, microscopic and endoscopic surgery), each with their own ergonomic considerations. The vast majority of urologists have experienced work-related musculoskeletal pain or injury at some point in their career, which can result in leaves of absence, medical and/or surgical treatment, burnout, changes of specialty and even early retirement. Surgical ergonomics in urology has been understudied and underemphasized. In this Review, we characterize the burden of musculoskeletal injury in urologists and focus on various ergonomic considerations relevant to the urology surgeon. Although the strength of evidence remains limited in this space, we highlight several practical recommendations stratified by operative approach that can be incorporated into practice without interrupting workflow whilst minimizing injury to the surgeon. These recommendations might also serve as the foundation for ergonomics training curricula in residency and continuing medical education programmes. With improved awareness of ergonomic principles and the sequelae of injury related to urological surgery, urologists can be more mindful of their operating room environment and identify ways of reducing their own symptoms and risk of injury.

Contemporary Assessment of the Most Cited Clinical, Basic Science, and Guidelines Papers in Urology: A Reference for Urology Journal Club.

OBJECTIVE: To perform bibliometric analysis of the top cited articles in urology as a guide for journal club article selection. METHODS: Bibliometric citation analysis was performed using Scopus. Tables illustrating the top cited clinical, basic science, and guidelines/position statements papers were constructed. Linear regression was used to determine association between h-index and number of citations. RESULTS: A total of 3,188,861 publications from 1788 to 2020 were analyzed. The top 100 cited clinical papers from 1788 to 2020, top 100 cited contemporary clinical papers from 2000 to 2020, top 25 cited basic science papers, and the top 25 cited guidelines/position statement papers were reported. Median number of citations in the top 100 cited clinical papers was 1463 (interquartile range 1186-1821). Memorial Sloan Kettering Cancer Center (12), Johns Hopkins University (6), and Harvard University (6) contributed the most top cited clinical papers in urology. Urologic oncology was the most represented subspecialty in both clinical (75%) and basic science (96%) papers. First author and last author h-index were found to correlate with the number paper citations in the top 100 cited clinical papers from 1788 to 2020 (first author ß:5.3, P= .003, last author ß:4.5, P= .03). Only 7% of the most cited clinical papers in urology were from female first authors, which was not statistically significantly different from those reported in prior publications published in 2009 and 2013. CONCLUSION: Contemporary citation analysis of indexed manuscripts in urology may serve as a valuable educational tool for urologists and trainees.

A Comparative Analysis of Surgical Scar Cosmesis Based on Operative Approach for Radical Prostatectomy.

Objective: Recent developments in minimally invasive approaches to radical prostatectomy (RP) for localized prostate cancer have improved oncological outcomes, but may also affect surgical scar cosmesis, an important component of survivorship and patient quality of life. Our aim was to evaluate surgical scar appearance based on operative approach to RP using a validated tool for evaluating psychosocial impact of scar appearance. Methods: Men between the ages of 45 and 80 were surveyed on an online crowdsourcing platform. Well-healed surgical scars after open, multiport (MP) robotic (transperitoneal and extraperitoneal), and single-port (SP) robotic RP were digitally rendered on stock photos to control for patient appearance. Respondents evaluated images using the SCAR-Q© psychosocial impact domain. Additionally, different RP scars were ranked by appearance and assigned 10-point appearance scores. Results: Two hundred thirty-four surveys were included for analysis (completion rate 84.2%). The median age was 54 (IQR: 49-61) and 35% (85/234) had previous abdominal surgery, of which 45% (38/85) was robotic or laparoscopic. SP scars had better psychosocial impact scores (median 100 out of 100 vs 69 and 58) than MP and open, respectively (both p < 0.001). SP scars were consistently ranked higher by appearance (median rank 1, IQR: 1-1) than MP (2, IQR: 2-3) and open (3, IQR: 3-4) (p < 0.001). SP without assistant port had the highest appearance score (median 9, IQR: 7-9) among all scars (p < 0.001). Conclusion: SP scars scored highest on psychosocial impact and were consistently ranked highest in appearance. These findings may be informative for optimizing both cosmetic appearance and quality of life for patients undergoing RP.

High-dimensional Cytometry (ExCYT) and Mass Spectrometry of Myeloid Infiltrate in Clinically Localized Clear Cell Renal Cell Carcinoma Identifies Novel Potential Myeloid Targets for Immunotherapy.

Renal Cell Carcinoma (RCC) is one of the most commonly diagnosed cancers worldwide with research efforts dramatically improving understanding of the biology of the disease. To investigate the role of the immune system in treatment-naïve clear cell Renal Cell Carcinoma (ccRCC), we interrogated the immune infiltrate in patient-matched ccRCC tumor samples, benign normal adjacent tissue (NAT) and peripheral blood mononuclear cells (PBMCs isolated from whole blood, focusing our attention on the myeloid cell infiltrate. Using flow cytometric, MS, and ExCYT analysis, we discovered unique myeloid populations in PBMCs across patient samples. Furthermore, normal adjacent tissues and ccRCC tissues contained numerous myeloid populations with a unique signature for both tissues. Enrichment of the immune cell (CD45+) fraction and subsequent gene expression analysis revealed a number of myeloid-related genes that were differentially expressed. These data provide evidence, for the first time, of an immunosuppressive and pro-tumorigenic role of myeloid cells in early, clinically localized ccRCC. The identification of a number of immune proteins for therapeutic targeting provides a rationale for investigation into the potential efficacy of earlier intervention with single-agent or combination immunotherapy for ccRCC.

Prostate Health Index and multiparametric magnetic resonance imaging to predict prostate cancer grade reclassification in active surveillance.

OBJECTIVE: To identify the value of combining the Prostate Health Index (PHI) and multiparametric magnetic resonance imaging (mpMRI), tools which have previously been shown to be independently predictive of prostate cancer (PCa) grade reclassification (GR; Gleason score >6), for the purpose of predicting GR at the next surveillance biopsy to reduce unnecessary prostate biopsies for men in PCa active surveillance (AS). PATIENTS AND METHODS: Between 2014 and 2019, we retrospectively identified 253 consecutive men in the Johns Hopkins AS programme who had mpMRI and PHI followed by a systematic ± targeted biopsy. PHI and PHI density (PHID) were evaluated across Prostate Imaging-Reporting and Data System version 2.0 (PI-RADSv2) scores and compared to those with and without GR. Next, the negative predictive value (NPV) and area under the receiver operating curve (AUC) were calculated to compare the diagnostic value of PI-RADSv2 score combined with PHI, PHID, or prostate-specific antigen density (PSAD) for GR using their respective first quartile as a cut-off. RESULTS: Of the 253 men, 38 men (15%) had GR. Men with GR had higher PHI values (40.7 vs 32.0, P = 0.001), PHID (0.83 vs 0.57, P = 0.007), and PSAD (0.12 vs 0.10, P = 0.037). A PI-RADSv2 ≤3 alone had a NPV of 91.6% for GR (AUC 0.67). Using a PHI cut-off of 25.6 in addition to PI-RADSv2 ≤3, the NPV and AUC were both increased to 98% and 0.70, respectively. Using a PSAD cut-off of 0.07 ng/mL/mL with PI-RADSv2 had an AUC of 0.69 and NPV of 95.4%. PHI and PI-RADSv2 together could have avoided 20% of biopsies at the cost of missing 2.6% of GRs. CONCLUSIONS: The combination of PHI and mpMRI can aid in the prediction of GR in men on AS and may be useful for decreasing the burden of surveillance prostate biopsies.

Effect of Pharmacologic Prophylaxis on Venous Thromboembolism After Radical Prostatectomy: The PREVENTER Randomized Clinical Trial.

BACKGROUND: Direct high-quality evidence is lacking evaluating perioperative pharmacologic prophylaxis (PP) after radical prostatectomy (RP) to prevent venous thromboembolism (VTE) leading to significant practice variation. OBJECTIVE: To study the impact of in-hospital PP on symptomatic VTE incidence and adverse events after RP at 30 d, with the secondary objective of evaluating overall VTE in a screening subcohort. DESIGN, SETTING, AND PARTICIPANTS: A prospective, phase 4, single-center, randomized trial of men with prostate cancer undergoing open or robotic-assisted laparoscopic RP was conducted (July 2017-November 2018). INTERVENTION: PP (subcutaneous heparin) plus routine care versus routine care alone. The screening subcohort was offered lower extremity duplex ultrasound at 30 d. OUTCOMES MEASUREMENTS AND STATISTICAL ANALYSIS: The primary efficacy outcome was symptomatic VTE incidence (pulmonary embolism [PE] or deep venous thrombosis [DVT]). Primary safety outcomes included the incidence of symptomatic lymphocele, hematoma, or bleeding after surgery. Secondary outcomes were overall VTE, estimated blood loss, total surgical drain output, complications, and surveillance imaging bias. Fisher's exact test and modified Poisson regression were performed. RESULTS AND LIMITATIONS: A total of 501 patients (75% robotic) were randomized and >99% (500/501) completed follow-up. At second interim analysis (N = 445), the symptomatic VTE rate was 2.3% (four PE + DVT and one DVT) for routine care versus 0.9% (one PE + DVT and one DVT) for PP (relative risk 0.40 [95% confidence interval 0.08-2.03], p = 0.3) meeting a futility threshold for early stopping. In the screening subcohort, the overall VTE rate was 3.3% versus 2.4% (p = 0.7). Results were similar at the final analysis (symptomatic VTE: 2.0% vs 0.8%, p = 0.3; overall VTE: 2.9% vs 2.8%, p = 1). No differences were observed in safety or secondary outcomes. All VTE events (seven symptomatic and three asymptomatic) occurred in patients undergoing pelvic lymph node dissection. CONCLUSIONS: This study was not able to demonstrate a statistically significant reduction in symptomatic VTE associated with PP. There was no increase in the development of symptomatic lymphoceles, bleeding, or other adverse events. Given that the event rate was lower than powered for, further research is needed among high-risk patients (Caprini score ≥8) or patients receiving pelvic lymph node dissection. PATIENT SUMMARY: In this report, we randomized patients undergoing radical prostatectomy to perioperative pharmacologic prophylaxis or routine care alone. We found that pharmacologic prophylaxis did not reduce postoperative symptomatic venous thromboembolism significantly for men at routine risk. Importantly, pharmacologic prophylaxis did not increase adverse events, such as formation of lymphoceles or bleeding, and can safely be implemented when indicated for patients with risk factors undergoing radical prostatectomy.

Transperineal prostate biopsy with cognitive magnetic resonance imaging/biplanar ultrasound fusion: description of technique and early results.

OBJECTIVE: To describe our technique and early results performing transperineal prostate biopsy using cognitive magnetic resonance imaging (MRI)/biplanar ultrasound fusion. Key components of this technique include use of the PrecisionPoint Transperineal Access System (Perineologic, Cumberland, MD) and simultaneous transrectal ultrasound guidance in the axial and sagittal planes. PATIENTS AND METHODS: In total, 95 patients (38 studied retrospectively and 57 studied prospectively) underwent a transperineal MRI-targeted prostate biopsy using the technique detailed in this manuscript. All biopsies were performed by a single urologist (MAG). Data were collected with respect to cancer detection rates, tolerability, and complications. The subset of patients who were studied prospectively was assessed for complications by telephone interviews performed at 4-6 days and 25-31 days following the prostate biopsy. RESULTS: Between February 2018 and June 2019, 95 men underwent a transperineal prostate biopsy using MRI/biplanar ultrasound fusion guidance. Patients had a total of 124 PI-RADS 3-5 lesions that were targeted for biopsy. In total, 108 (87.1%) lesions were found to harbor prostate cancer of any grade. Grade group ≥ 2 prostate cancer was found in 81 (65.3%) of targeted lesions. The detection rates for grade group ≥ 1 and grade group ≥ 2 prostate cancer rose with increasing PI-RADS score. In 65 (68.4%) cases, the patient's highest grade prostate cancer was found within an MRI target. Additionally, 12 of 55 (21.8%) patients who were found to have no or grade group 1 prostate cancer on systematic biopsy were upgraded to grade group ≥ 2 prostate cancer with MRI targeting. Only 1 (1.1%) patient received periprocedural antibiotics and no patient experienced an infectious complication. Self-limited hematuria and hematospermia were commonly reported following the procedure (75.4% and 40.4%, respectively) and only 1 (1.1%) patient developed urinary retention. CONCLUSIONS: We demonstrate the safety and feasibility of performing transperineal prostate biopsy using cognitive MRI/biplanar ultrasound fusion guidance. The described technique affords the safety benefits of the transperineal approach as well as obviates the need for a formal fusion platform. Additionally, this method can conveniently be performed under local anesthesia with acceptable tolerability.

Adjuvant radiation with androgen-deprivation therapy for men with lymph node metastases after radical prostatectomy: identifying men who benefit.

OBJECTIVES: To perform a comparative analysis of three current management strategies for patients with lymph node metastases (LNM; pN1) following radical prostatectomy (RP): observation, androgen-deprivation therapy (ADT), and external beam radiation therapy (EBRT) + ADT. PATIENTS AND METHODS: Patients with LNM after RP were identified using the National Cancer Database (2004-2013). Exclusion criteria included any use of radiation therapy or ADT before RP, clinical M1 disease, or incomplete follow-up data. Patients were categorised according to postoperative management strategy. The primary outcome was overall survival (OS). Kaplan-Meier curves and adjusted multivariable Cox proportional hazards models were employed. Sub-analyses further evaluated patient risk stratification and time to receipt of adjuvant therapy. RESULTS: A total of 8 074 patients met the inclusion criteria. Postoperatively, 4 489 (55.6%) received observation, 2 065 (25.6%) ADT, and 1 520 (18.8%) ADT + EBRT. The mean (median; interquartile range) follow-up was 52.3 (48.0; 28.5-73.5) months. Patients receiving ADT or ADT + EBRT had higher pathological Gleason scores, T-stage, positive surgical margin rates, and nodal burden. Adjusted multivariable Cox models showed improved OS for ADT + EBRT vs observation (hazard ratio [HR] 0.77, 95% confidence interval [CI] 0.64-0.94; P = 0.008) and vs ADT (HR 0.76, 95% CI: 0.63-0.93; P = 0.007). There was no difference in OS for ADT vs observation (HR 1.01, 95% CI: 0.87-1.18; P = 0.88). Findings were similar when restricting adjuvant cohorts for timing of adjuvant therapy. There was no difference in OS between groups for up to 2 549 (31.6%) patients lacking any of the following adverse features: ≥pT3b disease, Gleason score ≥9, three or more positive nodes, or positive surgical margin. CONCLUSIONS: For patients with LNM after RP, the use of adjuvant ADT + EBRT improved OS in the majority of patients, especially those with adverse pathological features. Conversely, adjuvant therapy did not confer significant OS benefit in up to 30% of patients without high-risk features, who may be managed with observation and forego the morbidity associated with immediate ADT or radiation.

Clinical and Radiographic Predictors of Great Vessel Resection or Reconstruction During Retroperitoneal Lymph Node Dissection for Testicular Cancer.

OBJECTIVE: To evaluate whether specific clinical or radiographic factors predict inferior vena cava (IVC) or abdominal aortic (AA) resection or reconstruction (RoR) at the time of postchemotherapy retroperitoneal lymph node dissection (RPLND) for germ cell tumors of the testicle. MATERIALS AND METHODS: Two hundred seventy-seven patients undergoing postchemotherapy RPLND at two institutions between 2005 and 2015 were identified. Preoperative imaging was reviewed with radiologists blinded to operative details. Univariable and multivariable logistic regressions were performed, and a model was created to predict the need for great vessel RoR using radiographic and clinical factors. RESULTS: Of 97 patients with preoperative imaging and clinical data available, 16 (17%) underwent RoR at RPLND. On univariable analysis dominant mass size, degree of circumferential vessel involvement, and vessel deformity were associated with RoR (all P <.05). No patients with clinical stage IIA or IIB disease at diagnosis required RoR. In the multivariable model, mass involvement of the IVC >135° (odds ratio 65.5, 7.8-548, P <.01) and involvement of the AA >330° (odds ratio 29.0, 3.44-245, P <.01) were predictive for RoR. These thresholds yielded a PPV of 48% and 50% and a NPV of 92% and 97% for IVC and AA RoR, respectively. CONCLUSION: Degree of circumferential involvement of the great vessels is an independent predictor for resection or reconstruction of the IVC or AA at postchemotherapy RPLND. Patients at high risk of great vessel reconstruction should be informed accordingly and have the proper teams available for complex vascular reconstruction.

A Prospective Cohort Study of Postdischarge Opioid Practices After Radical Prostatectomy: The ORIOLES Initiative.

Opioid pain medications are overprescribed, but few data are available to help in appropriate tailoring of postdischarge opioid prescriptions after surgery. Prior studies are retrospective and based on incomplete responses (<50%) to questionnaires, with small sample sizes for any particular surgery. The ORIOLES initiative was a prospective cohort study (2017-2018) designed to measure postdischarge opioid prescribing and use and clinical predictors of use for consecutive patients after radical prostatectomy. The objectives were to establish a postdischarge opioid reference value to meet the needs of >80% of patients and compare open and robotic surgery. A total of 205 adult patients were enrolled, with 100% completing follow-up. In units of oral morphine equivalents (OMEQ), a median of 225mg was prescribed and 22.5mg used. There was no difference by surgical approach or among patients with a history of pain-related diagnoses. Overall, 77% of postdischarge opioid medication was unused, with 84% of patients requiring ≤112.5mg OMEQ. Only 9% of patients appropriately disposed of leftover medication. Approximately 5% reported continued incisional pain due to surgery at 30d, but none required continued opioid medication use. Prescribing more opioids was independently associated with greater opioid use in adjusted models. PATIENT SUMMARY: In this report, we looked at opioid medication use following discharge after radical prostatectomy. We found that 77% of opioid pain medication prescribed was unused, with 84% of patients using less than half of their prescription. Prescribing more opioids was associated with greater use; only 9% of patients appropriately disposed of leftover medication.
