A prospective evaluation of the prostate microbiome in malignant and benign tissue using transperineal biopsy.

BACKGROUND: The link between the prostate microbiome and prostate cancer remains unclear. Few studies have analyzed the microbiota of prostate tissue, and these have been limited by potential contamination by transrectal biopsy. Transperineal prostate biopsy offers an alternative and avoids fecal cross-contamination. We aim to characterize the prostate microbiome using transperineal biopsy. METHODS: Patients with clinical suspicion for prostate cancer who were to undergo transperineal prostate biopsy with magnetic resonance imaging (MRI) fusion guidance were prospectively enrolled from 2022 to 2023. Patients were excluded if they had Prostate Imaging Reporting and Data System lesions with scores ≤ 3, a history of prostate biopsy within 1 year, a history of prostate cancer, or antibiotic use within 30 days of biopsy. Tissue was collected from the MRI target lesions and nonneoplastic transitional zone. Bacteria were identified using 16S ribosomal RNA gene sequencing. RESULTS: Across the 42 patients, 76% were found to have prostate cancer. Beta diversity indices differed significantly between the perineum, voided urine, and prostate tissue. There were no beta diversity differences between cancerous or benign tissue, or between pre- and postbiopsy urines. There appear to be unique genera more abundant in cancerous versus benign tissue. There were no differences in alpha diversity indices relative to clinical findings including cancer status, grade, and risk group. CONCLUSIONS: We demonstrate a rigorous method to better characterize the prostate microbiome using transperineal biopsy and to limit contamination. These findings provide a framework for future large-scale studies of the microbiome of prostate cancer.

Preoperative optimization of the radical cystectomy patient: Current state and future directions.

Radical cystectomy (RC) is associated with high rates of morbidity and mortality despite adoption of robotics and implementation of enhanced recovery after surgery protocols. There have been increased efforts to investigate preoperative optimization through comprehensive nutritional evaluation, preoperative supplementation, and prehabilitation outside of previously described enhanced recovery after surgery protocols to reduce mortality and morbidity from RC. In this review, we summarize and evaluate the current literature on preoperative assessment and optimization in RC.

Robotic-assisted enucleation for renal masses: A comparison of on-clamp and off-clamp approach.

INTRODUCTION: In surgically excising renal masses, studies have demonstrated that tumor enucleation is an effective option. However, there is limited literature comparing off-clamp to on-clamp tumor enucleation. MATERIALS AND METHODS: We retrospectively reviewed the charts of 189 patients who underwent robotic-assisted laparoscopic partial nephrectomy via tumor enucleation by a single surgeon from March 2012 and April 2022. Patients were stratified based on use of renal hilar clamping intraoperatively. Surgical, oncologic, and renal functional outcomes were captured. Variables were analyzed and compared between the two groups using Student's T-tests and Chi-square tests. RESULTS: Of 189 procedures analyzed, 124 were performed on-clamp and 65 were performed off-clamp. There were no differences in patient demographics or average length of follow-up. There were no differences in estimated blood loss, complications, or hospital length of stay. Recurrence rates were similar for the two groups. The absolute difference in estimated glomerular filtration rate change between the two groups at time of first follow-up was not significant (p = 0.25). CONCLUSIONS: There is no significant difference in perioperative outcomes such as surgical time, blood loss, or complications between the two groups. Furthermore, there was no significant difference in postoperative kidney function between the two techniques.

The evolution of tumor enucleation partial nephrectomy: A comparison of perioperative outcomes for sutureless hemostatic bandage as an alternative to standard renorrhaphy.

BACKGROUND: The standard approach to hemostasis during partial nephrectomy (PN) is to perform suture renorrhaphy (SR). Application of a hemostatic bandage (HB) is an alternative to minimize blood loss and devitalized renal parenchyma. We aim to evaluate perioperative outcomes of PN with tumor enucleation (TE) comparing SR to HB. METHODS: We analyzed a retrospective cohort of 195 patients undergoing robot-assisted laparoscopic PN with TE performed at a tertiary referral center (2012-2022). Hemostasis was obtained with SR in 54 patients while 141 patients underwent application of HB consisting of Surgicel®, Gelfoam® soaked in thrombin, and Floseal®. RESULTS: SR patients had tumors of greater complexity by RENAL nephrometry score compared to HB patients (p < 0.001). Operative time (141 vs. 183 min, p < 0.001), warm ischemia time (11.6 vs. 24.2 min, p < 0.001), estimated blood loss (37 vs. 214 mL, p < 0.001), and length of stay (1.2 vs. 1.8 days, p < 0.001) favored HB. There was no significant difference in Clavien-Dindo grade ≥3 complications (p = 0.22). Renal function was comparable with mean estimated glomerular filtration rate decrease of 0.66 and 0.54 mL/min/1.73 m2 at 3 months postoperatively for HB and SR, respectively (p = 0.93). CONCLUSIONS: Application of an HB is a safe alternative to SR for hemostasis following PN with TE in appropriately selected patients.

Pain Management Strategies in Contemporary Penile Implant Recipients.

PURPOSE OF REVIEW: To review the most recent literature citing opioid-sparing multimodal analgesic strategies used to manage perioperative pain in patients who underwent inflatable penile prosthesis (IPP) surgery and to provide the penile implant surgeon a variety of non-opioid-based pain management strategies for IPP management. RECENT FINDINGS: Interventions performed in the pre-operative, intraoperative, and post-operative arenas have all been shown to effectively lower pain scores and reduce opioid consumption. Certain surgical techniques performed during IPP surgery have helped with post-operative discomfort patients may feel after surgery. Multimodal analgesia (MMA) protocols adopted from other surgical fields and other urologic subspecialties that are implemented in IPP surgery have promising results with regard to post-operative pain control and opioid consumption. Protocols that implement a combination of refined surgical technique and multimodal analgesia offer substantial benefit to patients undergoing IPP surgery. Further work is needed to assess long-term pain control and opioid use in patients that undergo IPP surgery using these innovative strategies.

Evaluating the Impact of the Standardized Letter of Recommendation on a Successful Match in Urology Residency.

OBJECTIVE: To evaluate the contribution of the standardized letter of recommendation (SLOR) to the likelihood of matching in urology residency by applying a novel scoring system and characterize utilization in the 2022 application cycle. METHODS: We conducted an investigation of all applicants to our urology residency program during the 2022 cycle. We developed a scoring system to assess SLOR strength across all templates. Match outcomes were verified with the Society of Academic Urologists listing. Statistical analysis was performed to assess for factors predictive of a successful match. RESULTS: Out of 386 total applicants, 239 (61.9%) had at least 1 SLOR in their application. SLOR utilization was more prevalent in MD applicants, in those with higher Step 2 scores, and in those who matched (P <.01). The majority of SLOR scores (66.5%) were above a 3.5/5 in our cohort. Step 1 score, number of research entries, and presence of an SLOR were predictive of successful match. However, a SLOR score of <3 was strongly associated with not matching (OR 0.021, P <.01). CONCLUSION: The presence of a SLOR in our cohort overall was associated with a successful match. A poor SLOR score was highly deleterious to an applicant's chance of matching in urology. Our SLOR scoring system can be used across all letter templates and demonstrates that strength of SLOR can significantly impact an applicant's chance of matching.

Robotic transperitoneal versus retroperitoneal approach for anterior renal mass nephron-sparing surgery.

Robotic nephron-sparing surgery is traditionally performed via a transperitoneal (TP) approach. However, the retroperitoneal (RP) approach has gained popularity, particularly for posterolateral renal masses. The RP approach is associated with shorter operative time, less blood loss, and shorter length of stay, while preserving oncologic outcomes in selected masses. Here, we aim to assess the feasibility of the RP approach in excising anterior renal masses. Patients ≥ 18 years of age who underwent robotic nephron-sparing surgery for anterior renal masses were retrospectively identified (2008-2022). Baseline demographics, tumor characteristics, and perioperative data were collected and characterized based on TP vs RP approaches. Wilcoxon rank sum test and Pearson's Chi-squared test were used to compare continuous and categorical variables, respectively. Two hundred and sixteen patients were included-178 (82.4%) underwent TP approach and 38 (17.6%) underwent RP approach. Baseline demographics, preoperative tumor size, and renal nephrometry scores were similar. The RP approach was associated with shorter operative (150 vs 203 min, p < 0.001) and warm ischemia time (12 vs 21 min, p < 0.001), and less blood loss (20 vs 100 cc, p = 0.002) (Table 1). The RP approach was associated with shorter length of stay (1 vs 2 days, p < 0.001) and less total complications (5.3% vs 19.1%, p = 0.038). Major complication (Clavien-Dindo Grade > 3) rates were similar. There was no difference in positive surgical margin rates or pathologic characteristics. Robotic RP approach for nephron-sparing surgery is feasible for eligible anterior tumors and is associated with favorable perioperative outcomes with preserved negative surgical margin rates.

Neoadjuvant Chemotherapy Before Radical Cystectomy for Muscle-Invasive Bladder Cancer: Elective and Eligibility Factors Impacting Utilization.

INTRODUCTION: We aimed to assess utilization of neoadjuvant chemotherapy (NAC) and etiologies for lack of NAC receipt among patients with muscle-invasive bladder cancer (MIBC). METHODS: Patients diagnosed with MIBC undergoing radical cystectomy at a single institution (2005-2021) were included. Patients were categorized by receipt of NAC, and reasons for no NAC were categorized into eligibility and elective factors. Overall survival was analyzed using univariable and multivariable Cox proportional hazards regression models and modeled with Kaplan-Meier curves. RESULTS: Three hundred eighty patients with MIBC were included; 154 (40.5%) received NAC. Patients were not candidates for NAC due to renal dysfunction (16.6%), clinical contraindications (4.7%), salvage setting (2.1%), and histology (5.3%; total N = 109). Among 271 (71.3%) who were eligible, utilization increased from early (2005-2016) to recent (2016-2021) time periods (34.2% to 85.7% among NAC-eligible, P < .001; 22.8% vs 67.1% among all MIBC, P < .001). Elective factors for not receiving NAC included patient symptoms (7.8%), disease progression concern (7.0%), patient preference/refusal (20.3%) and provider discretion (8.1%) among 271 NAC-eligible patients. Notably, patient preference/refusal decreased from 33.6% to 3.4% in recent years (P < .001). On multivariable analysis, lack of NAC utilization due to renal dysfunction (HR 2.18, P = .002), clinical contraindications (HR 2.62, P = .01), and elective factors (HR 1.88, P = .01) were associated with worse overall survival. CONCLUSIONS: NAC utilization increased over time with 85.7% of eligible patients with MIBC receiving NAC in recent years. Renal dysfunction, patient preference, and clinical contraindications were primary etiologies for lack of NAC. Fewer patients refused NAC in recent years leading to a potential ceiling for NAC utilization.

Quantifying preserved renal volume and function in patients undergoing standard partial nephrectomy vs. tumor enucleation for localized renal tumors.

INTRODUCTION: Renal parenchymal volume loss from standard partial nephrectomy (SPN) is a significant prognosticator for postoperative renal function. Tumor enucleation (TE) minimizes parenchymal loss compared to SPN. Little is known regarding discrete changes in renal function associated with volume loss. We sought to quantify the differences between SPN and TE in preserving parenchymal volume and estimated glomerular filtration rate (eGFR). METHODS: We identified 420 patients who underwent robotic partial nephrectomy (SPN or TE) at our tertiary care center from 2009 to 2022. Parenchymal volumes were calculated using TeraRecon 3D reconstruction software from axial imaging performed preoperatively and within 6 months postoperatively. Renal volume preserved and renal function were evaluated with multivariable linear and logistic regression models. RESULTS: At 1 year, eGFR was 7% lower in patients undergoing SPN compared to TE (P < 0.01). Across both SPN and TE, only volume of preserved parenchyma was predictive of eGFR and chronic kidney disease (CKD) progression (both P < 0.01). TE preserved more healthy parenchymal volume compared to SPN (median percentage 97.6% vs 89.2%; P < 0.001). Each 1% of volumetric loss corresponded to a 0.35% decrease in eGFR at 1 year postoperatively (P < 0.01). CONCLUSIONS: Volume of preserved renal parenchyma was the strongest factor associated with preserved eGFR and reduced odds of CKD progression. TE preserved more parenchyma than SPN, which translated to higher eGFR preservation at 1 year postoperatively.

Variations in germ cell tumor histology by age and implications for cancer-specific survival among pediatric and adult males: A population-based study.

PURPOSE: Few studies have quantified differences in histology and implications for survival between male children and adults with germ cell tumors (GCT). We evaluated these differences and associations with cancer-specific survival (CSS) using Surveillance, Epidemiology, and End Results (SEER) cancer registries. METHODS: SEER (1988-2016) was used to identify male patients 0 to 40 years of age diagnosed with seminoma and nonseminomatous GCT (NSGCT). Demographic and tumor characteristics were tabulated with histology distributions compared by age group (0-4, 12-18, 19-40 years old). CSS was evaluated in multivariable Cox proportional hazards regression models. RESULTS: Among 27,204 patients identified, 1,538 (5.7%) were pediatric (0-18 years). Seminoma (54.3%) predominated in adult patients (ages 19-40). Among 0 to 4 years-old, yolk sac tumor (71.2%) and teratoma (21.5%) were most common. Mixed GCT (52.7%) was most prevalent among 12 to 18 years-old with seminoma, embryonal, and teratoma occurring in 12 to 15% each. Relative to pediatric patients, adult patients had similar CSS for seminoma but worse CSS for NSGCT on Kaplan-Meier curves with 9 years mean follow-up. Choriocarcinoma and yolk sac tumors carried the worst prognosis relative to seminoma for both children (HR 5.7 and HR 11.1, respectively, both P < 0.01) and adults (HR 4.6 and HR 4.6, respectively, both P < 0.01) adjusted for stage. CONCLUSION: Histology of GCTs vary by age with yolk sac tumors and teratoma predominating for male patients 0 to 4 years, mixed GCT for 12 to 18 years, and seminoma for 19 to 40 years. Pediatric patients with NSGCT had higher CSS than their adult counterparts. Mixed GCT represented an increasing proportion of GCT over the study period. Age, stage, and histology impact CSS in both pediatric and adult populations.

MRI at diagnostic versus confirmatory biopsy during MRI-based active surveillance of prostate cancer.

OBJECTIVES: Active surveillance (AS) is a management strategy for patients with favorable risk prostate cancer. Multi-parametric magnetic resonance imaging (mpMRI) may impact upgrading rates, but there is mixed evidence on the appropriate timing to introduce mpMRI. We evaluated timing of initial mpMRI use for patients on AS and compared upgrading and intervention rates for AS candidates who received initial mpMRI before diagnostic biopsy vs. confirmatory biopsy. SUBJECTS AND METHODS: Patients enrolled in AS captured by the Prospective Loyola Urology mpMRI (PLUM) Prostate Biopsy Cohort which captures men undergoing MRI-fusion prostate biopsy. We included patients enrolled in AS between January 2014 and October 2022. We conducted a retrospective analysis of patients who underwent MRI-fusion prostate biopsy while on AS at our institution. The cohort was stratified by men who underwent first mpMRI prior to diagnostic biopsy (MRI-DBx), confirmatory biopsy (MRI-CBx), or a subsequent surveillance biopsy. Oncologic outcomes including pathologic reclassification, intervention-free survival, progression-free survival, and overall survival were evaluated. RESULTS: Of 346 patients identified on AS, 94 (27.2%) received mpMRI at the time of diagnostic biopsy, 182 (52.6%) at confirmatory biopsy, and 70 (20.2%) at a later biopsy. At confirmatory biopsy (median 14 months), there was no difference in upgrading (HR 0.95, P = 0.78) or intervention rates (HR 0.97, P = 0.88) between MRI-DBx and MRI-CBx. PI-RADS score on initial mpMRI was associated with upgrading during AS follow-up relative to men with negative mpMRI (HR 4.20 (P = 0.04), 3.24 (P < 0.001), and 1.99 (P < 0.001) for PI-RADS 5, 4, and 3, respectively), and PSA density was associated with intervention (HR 1.52, P = 0.03). CONCLUSION: mpMRI can serve as a prognostic tool to select and monitor AS patients, but there was no difference in upgrading or intervention rates based on initial timing of MRI.

Risk of pseudoaneurysm and bleeding complications after partial nephrectomy: comparison of tumor enucleation to standard margin technique.

Partial nephrectomy (PN) is the gold standard for the resection of amenable small renal masses. Some surgeons have adopted tumor enucleation (TE) over the standard margin PN (SPN) technique based on preservation of healthy renal parenchyma by following the tumor pseudocapsule. However, TE may also confer additional advantages due to avoidance of sharp incision including reduction in perioperative and bleeding complications. Therefore, we evaluated the rate of pseudoaneurysms and other complications following TE vs. SPN. A retrospective cohort study of patients undergoing PN (TE and SPN) between 2008 and 2020 was conducted. Baseline characteristics were compared between the TE and SPN cohorts with univariable and multivariable logistic regression models. A total of 534 patients were included, 195 (36.5%) receiving TE and 339 (63.5%) SPN. There were no differences in baseline patient demographics. There was no difference in RENAL nephrometry scores between the two groups (p = 0.47). TE had lower rates of postoperative complications (11.3 vs. 21.5%, p = 0.002). TE had less bleeding complications (2.1 vs. 8.0%, p = 0.002) with no pseudoaneurysm events following TE compared to 12 following SPN (0.0 vs. 3.5%, p = 0.008). Need for interventional radiology largely reflected pseudoaneurysm differences (0 (0.0%) TE vs. 13 (3.8%) SPN, p = 0.006. Readmission occurred less often after TE vs. SPN (4.1 vs. 8.3%, p = 0.07). Patients receiving TE experienced no clinically significant pseudoaneurysm formation and were less likely to have any bleeding complication or major complication postoperatively. TE may be preferred when minimizing morbidity aligns with patient selection and preferences.

Comparison of Magnetic Resonance Imaging-Based Risk Calculators to Predict Prostate Cancer Risk.

Importance: Magnetic resonance imaging (MRI)-based risk calculators can replace or augment traditional prostate cancer (PCa) risk prediction tools. However, few data are available comparing performance of different MRI-based risk calculators in external cohorts across different countries or screening paradigms. Objective: To externally validate and compare MRI-based PCa risk calculators (Prospective Loyola University Multiparametric MRI [PLUM], UCLA [University of California, Los Angeles]-Cornell, Van Leeuwen, and Rotterdam Prostate Cancer Risk Calculator-MRI [RPCRC-MRI]) in cohorts from Europe and North America. Design, Setting, and Participants: This multi-institutional, external validation diagnostic study of 3 unique cohorts was performed from January 1, 2015, to December 31, 2022. Two cohorts from Europe and North America used MRI before biopsy, while a third cohort used an advanced serum biomarker, the Prostate Health Index (PHI), before MRI or biopsy. Participants included adult men without a PCa diagnosis receiving MRI before prostate biopsy. Interventions: Prostate MRI followed by prostate biopsy. Main Outcomes and Measures: The primary outcome was diagnosis of clinically significant PCa (grade group ≥2). Receiver operating characteristics for area under the curve (AUC) estimates, calibration plots, and decision curve analysis were evaluated. Results: A total of 2181 patients across the 3 cohorts were included, with a median age of 65 (IQR, 58-70) years and a median prostate-specific antigen level of 5.92 (IQR, 4.32-8.94) ng/mL. All models had good diagnostic discrimination in the European cohort, with AUCs of 0.90 for the PLUM (95% CI, 0.86-0.93), UCLA-Cornell (95% CI, 0.86-0.93), Van Leeuwen (95% CI, 0.87-0.93), and RPCRC-MRI (95% CI, 0.86-0.93) models. All models had good discrimination in the North American cohort, with an AUC of 0.85 (95% CI, 0.80-0.89) for PLUM and AUCs of 0.83 for the UCLA-Cornell (95% CI, 0.80-0.88), Van Leeuwen (95% CI, 0.79-0.88), and RPCRC-MRI (95% CI, 0.78-0.87) models, with somewhat better calibration for the RPCRC-MRI and PLUM models. In the PHI cohort, all models were prone to underestimate clinically significant PCa risk, with best calibration and discrimination for the UCLA-Cornell (AUC, 0.83 [95% CI, 0.81-0.85]) model, followed by the PLUM model (AUC, 0.82 [95% CI, 0.80-0.84]). The Van Leeuwen model was poorly calibrated in all 3 cohorts. On decision curve analysis, all models provided similar net benefit in the European cohort, with higher benefit for the PLUM and RPCRC-MRI models at a threshold greater than 22% in the North American cohort. The UCLA-Cornell model demonstrated highest net benefit in the PHI cohort. Conclusions and Relevance: In this external validation study of patients receiving MRI and prostate biopsy, the results support the use of the PLUM or RPCRC-MRI models in MRI-based screening pathways regardless of European or North American setting. However, tools specific to screening pathways incorporating advanced biomarkers as reflex tests are needed due to underprediction.

Incidental Discovery of Hepatocellular Carcinoma on 18F-PSMA PET CT Performed for Prostate Cancer Reassessment.

Prostate-specific membrane antigen positron emission tomography (PSMA PET) has been approved by the Food and Drug Administration (FDA) to identify prostate cancer in the setting of biochemical recurrence but can also identify other malignancies. 18F-PSMA PET has not been studied as a potential tool for hepatocellular carcinoma (HCC). We describe the case of a 76-year-old male with a rising prostate-specific antigen (PSA) after definitive prostate cancer treatment and no prior liver pathology who was incidentally found to have HCC on 18F-PSMA PET.

Profound facial bleeding after buccal mucosa graft harvest - A rare case of facial artery pseudoaneurysm.

Facial artery pseudoaneurysms are exceedingly rare events that can occur as a complication of oral maxillofacial surgery or facial trauma. The management of such pseudoaneurysms following buccal mucosa graft harvest for urinary reconstructive indications has not previously been described. Here, we describe a facial artery pseudoaneurysm that presented as repeated, episodic facial bleeding episodes following buccal mucosal harvest for a patient undergoing urethroplasty.

Estradiol-secreting adrenal oncocytoma in a 31-year old male.

Oncocytic adrenocortical tumors (OAT) are rare and often are non-functional. We report a unique case of an estradiol-secreting adrenal oncocytoma in a 31-year-old male discovered upon an infertility and gynecomastia work-up. After resection of the 9 cm adrenal mass, the patient's estradiol levels normalized from 83.2 pg/ml to 19.0 pg/ml. Gonadotropins and serum dehydroepiandrosterone sulfate also normalized.

Enhanced recovery strategies after penile implantation: a narrative review.

Optimizing pain management strategies in penile implantation has historically been a challenge to urologists assuming care of patients post-operatively. In addition to the complex pathophysiology of male genital pain, the responsibility of opioid stewardship in the face of the ongoing narcotics epidemic presents its own set of challenges to experienced implanters. Recent innovations in pre- and intra-operative analgesia have provided some improvement in patient-reported pain outcomes. When used together in protocols spanning each phase of operative care, multimodal analgesia (MMA) regimens provide superior patient pain control and successfully decrease opioid usage compared to traditional opioid-based pain control. This review will systematically present literature that discusses interventions in the preoperative and intraoperative spaces aimed at optimally controlling pain. We will also highlight surgical techniques that have been demonstrated to help ameliorate post-operative pain in penile implant recipients. We will discuss the impact of MMA protocols across urology and further explore its larger impact on reducing opioid burden in the ongoing epidemic.

Prescribing Trends in Post-operative Pain Management After Urologic Surgery: A Quality Care Investigation for Healthcare Providers.

OBJECTIVE: To assess prescribing and refilling trends of narcotics in postoperative urology patients at our institution. Although the opioid epidemic remains a public health threat, no series has assessed prescribing patterns across urologic surgery disciplines following discharge. METHODS: All urologic surgeries were retrospectively reviewed from May 2017-April 2018. Demographics, comorbidities, and postoperative pain management strategies were analyzed. Narcotics usage following surgery were reported in total morphine equivalents (TME). Opioid refill rate was characterized by medical specialty and stratified by urologic discipline. RESULTS: 817 cases were reviewed. Mean age and TME at discharge was 57±15.6 years and 35.43±19.5 mg, respectively. 13.6% (mean age 55±15.9) received a narcotic refill following discharge (mean TME/refill 37.7±28.9 mg). A higher proportion of patients with a pre-operative opioid prescription received a refill compared to opioid naïve patients (38.2% vs 21.6%, P < .01). Refill rate did not differ between urologic subspecialties (P = .3). Urologists were only responsible for 20.4% of all refills filled, despite all patients continuing follow-up with their surgeon. Procedures with the highest rates of post-operative refills were in oncology, male reconstruction/trauma and endourology. Patients with a history of chronic pain (OR 1.9, CI 1.1-3.3) preoperative narcotic prescription (OR 1.6, CI 1.0-2.6), and higher ASA score (OR 1.8, CI 1.6-2.8) were more likely to obtain a postoperative opioid prescription refill. CONCLUSION: Approximately 1 in 7 postoperative urology patients receive a postoperative narcotics refill; however, nearly two-thirds receive refills exclusively from non-urologic providers. Attempts to avoid overprescribing of postoperative narcotics need to account for both surgeon and nonsurgeon sources of opioid refills.

Pain management strategies in penile implantation.

The opioid epidemic continues to be a serious public health concern. Many have pointed to prescription drug misuse as a nidus for patients to become addicted to opioids and as such, urologists and other surgical subspecialists must critically define optimal pain management for the various procedures performed within their respective disciplines. Controlling pain following penile prosthesis implantation remains a unique challenge for urologists, given the increased pain patients commonly experience in the postoperative setting. Although most of the existing urological literature focuses on interventions performed in the operating room, there are many studies that examine the role of preoperative adjunctive pain medicine in diminishing postoperative narcotic requirements. There are relatively few studies looking at postoperative strategies for managing pain in prosthetic surgery with follow-up past the immediate hospitalization. This review assess the various strategies employed for managing pain following penile implantation through the lens of the current state of the opioid crisis, thus examining how urologists can responsibly treat pain without contributing to the growing threat of opioid addiction.
