ABSTRACT

PURPOSE OF REVIEW: Management of urotrauma is a crucial part of a urologist's knowledge and training. We therefore sought to understand the state of urotrauma education in the United States. RECENT FINDINGS: Using themes of "Urotrauma" and "Education," we performed a systematic review and meta-analysis by searching for studies in MEDLINE, all Cochrane libraries, EMBASE, BIOSIS, Scopus, and Web of Science through May 2023. The primary outcome was the pooled rate of urology trainee and program director attitudes toward urotrauma education. Secondary outcomes involved a descriptive summary of existing urotrauma curricula and an assessment of factors affecting urotrauma exposure. Of 12,230 unique records, 11 studies met the final eligibility criteria, and we included 2 in the meta-analysis. The majority of trainees and program directors reported having level 1 trauma center rotations (range 88-89%) and considered urotrauma exposure as an important aspect of residency education (83%, 95% CI 76-88%). Despite possible increases in trainee exposure to Society of Genitourinary Reconstructive Surgeons (GURS) faculty over the preceding decade, nearly a third of trainees and program directors currently felt there remained inadequate exposure to urotrauma during training (32%, 95% CI 19-46%). Factors affecting urotrauma education include the limited exposure to GURS-trained faculty and clinical factors such as case infrequency and non-operative trauma management. Urology resident exposure to urotrauma is inadequate in many training programs, underscoring the potential value of developing a standardized curriculum to improve urotrauma education for trainees. Further investigation is needed to characterize this issue and to understand how it impacts trainee practice readiness.

ABSTRACT

AIMS: To examine the rate of lower urinary tract complications (LUTC) and urinary diversion (UD) after artificial urinary sphincter (AUS) explantation with the acute reconstruction of AUS cuff erosion defects. METHODS: We performed a retrospective study of patients who underwent in-situ urethroplasty (ISU) for AUS cuff erosion from June 2007 to December 2020. Outcomes included LUTC (urethral stricture, diverticulum, fistula), AUS reimplantation, and UD. Defect size was prospectively estimated acutely and a subanalysis was performed to determine the impact of erosion severity (small erosions [<33% circumferential defect] and large erosions [≥33%]) on these outcomes. Kaplan-Meier curves were created to compare survival between the two groups. RESULTS: A total of 40 patients underwent ISU for urethral cuff erosion. The median patient age was 76 years old with a median erosion circumference of 46%. The overall LUTC rate was 30% (12/40) with 35% (14/40) of patients requiring permanent UD. Secondary AUS placement occurred in 24/40 (60%) patients with 11/24 (46%) leading to repeat erosion. On subanalysis, small erosion was associated with improved LUTC-free and UD-free survival but not associated with AUS reimplantation. CONCLUSIONS: Lower urinary tract complications are common after AUS cuff erosion and can lead to the need for permanent UD. Patients with larger erosions are more likely to undergo UD and reach this end-stage condition earlier compared to patients with small erosions.

ABSTRACT

OBJECTIVES: To examine the current molecular therapeutics in the medical treatment of recurrent ischemic priapism (RIP). To propose a stepwise clinical management paradigm for the treatment of RIP. METHODS: We performed a literature search using the PubMed database for the terms 'recurrent ischemic priapism' and 'stuttering priapism' up until December 2020. We assessed pre-clinical and clinical studies regarding medical management of RIP and molecular pathophysiology. Case series and randomized trials were evaluated by study quality and patient outcomes to determine a potential clinical management scheme. RESULTS: Recent research has fostered an improved understanding of the underlying molecular pathophysiology of RIP that has paved the way forward for developing new therapeutic agents. Medications targeting neurovascular, hormonal and haematological mechanisms associated with RIP show great promise towards remedying this condition. A host of therapeutic agents operating across different mechanistic directions may be implemented according to a clinical management scheme to potentially optimize RIP outcomes. CONCLUSION: RIP remains a medically neglected condition with current management focused on treating the acute condition rather than modulating the course of disease. Continued research into the molecular mechanisms of RIP and standardized clinical pathways can improve the quality of care for patients suffering from this condition.

ABSTRACT

BACKGROUND: Inflatable penile prosthesis (IPP) reservoirs are typically placed into the Space of Retzius (SOR) or alternative locations including the High Submuscular (HSM) space via transinguinal (TI) or counter incision (CI) techniques. A cadaver study showed variability in reservoir location after TI-HSM placement. AIM: To evaluate reservoir location using cross-sectional imaging following IPP insertion. METHODS: We retrospectively reviewed our institutional database and identified men who underwent virgin penoscrotal IPP insertion between 2007 and 2019. We then identified those men who subsequently underwent cross-sectional imaging prior to October 2019. Radiologists evaluated cross-sectional imaging in a blinded manner and categorized reservoir locations as follows: 1) submuscular; 2) posterior to the external oblique fascia and lateral to the rectus abdominis musculature; 3) preperitoneal; 4) retroperitoneal; 5) intraperitoneal; 6) inguinal canal; 7) subcutaneous. Patients were stratified by reservoir placement technique, transinguinal space of Retzius (TI-SOR), transinguinal high submuscular (TI-HSM), or counterincision high submuscular (CI-HSM). Clinical characteristics and outcomes were reviewed and compared. Statistical analysis was performed using Chi-squared and Fisher's exact tests. OUTCOMES: Variability exists in the TI placement of SOR and HSM reservoirs, CI-HSM reservoirs were associated with a low level of variability. RESULTS: Among 561 men who underwent virgin IPP insertion during the 12-year study period, 114 had postoperative cross-sectional imaging (29 TI-SOR, 80 TI-HSM, and 5 CI-HSM). Among the 114 patients imaged, TI-HSM reservoirs were more likely than TI-SOR to be located anterior to the transversalis fascia (48 vs 14%, P < .01) and were less likely to be located in the preperitoneal space (18 vs 62%, P < .01). Rates of intraperitoneal reservoir location were similar between the TI-HSM and TI-SOR groups (5 vs 7%, P = .66). Among imaged CI-HSM reservoirs, 4 (80%) were anterior to the transversalis fascia and 1 (20%) was within the inguinal canal. Among all 536 transinguinal cases (131 TI-SOR and 405 TI-HSM), rates of reservoir-related complications requiring operative intervention were similar between groups (5 vs 2%, P = .24). No complications were noted among the 25 patients in the CI-HSM cohort. CLINICAL IMPLICATIONS: The level of variability seen in this study did not seem to impact patient safety, complications were rare in all cohorts. STRENGTHS AND LIMITATIONS: This study is the first and largest of its kind in evaluating reservoir positioning in live patients with long-term follow-up. This study is limited in its retrospective and nonrandomized nature. CONCLUSIONS: Despite variability with both TI-HSM and TI-SOR techniques, reservoir related complications remain rare.

ABSTRACT

AIMS: To evaluate the relationship between serum testosterone (T) levels and artificial urinary sphincter (AUS) cuff erosion in a population of incontinent men who underwent AUS placement. METHODS: A retrospective analysis of our single-surgeon AUS database was performed to identify men with T levels within 24 months of AUS placement. Men were stratified into two groups based on serum testosterone: low serum testosterone (LT) (<280 ng/dl) and normal serum testosterone (NT) (>280 ng/dl). Multivariable analysis was performed to control for risk factors. The outcome of interest was the incidence of and time to spontaneous urethral cuff erosion; other risk factors for cuff erosion were also evaluated. RESULTS: Among 161 AUS patients with serum testosterone levels, 84 (52.2%) had LT (mean: 136.8 ng/dl, SD: 150.4 ng/dl) and 77 (47.8%) had NT (mean: 455.8 ng/dl, SD: 197.3 ng/dl). Cuff erosion was identified in 42 men (26.1%) at a median of 7.1 months postoperatively (interquartile range: 3.6-13.4 months), most of whom (30/42, 71.4%) were testosterone deficient. LT levels were less common (54/119, 45.4%) in the non-erosion cohort (p = 0.004). Men with low T were nearly three times as likely to suffer AUS erosion than men with normal T (odds ratio = 2.519, p = 0.021). LT level was the only factor associated with AUS erosion on multivariable analysis. CONCLUSIONS: LT is an independent risk factor for AUS cuff erosion. Men with LT are more likely to present with cuff erosion, but there is no difference in time to erosion.

ABSTRACT

PURPOSE OF REVIEW: To review risk factors for AUS complications and present a systematic approach to their diagnosis and management. RECENT FINDINGS: Established risk factors for AUS complications include catheterization, channel TURP, pelvic radiation, urethroplasty, anticoagulation, cardiovascular disease, diabetes mellitus, frailty index, hypertension, low albumin, and low testosterone. We present our algorithm for diagnosis and management of AUS complications. Despite being the gold standard of treatment for men with SUI, major and minor complications can occur at any point after AUS insertion. Careful consideration of the urologic, medical, and operative risk factors for each patient can help prevent complications. A systematic approach to early and late complications facilitates their identification and effective management. The evaluating urologist must have a thorough understanding of potential AUS complications in order to restore quality of life in men with bothersome SUI.

ABSTRACT

INTRODUCTION Patient-reported pads per day use is a widely used metric in grading the severity of stress urinary incontinence and guiding surgical decision-making, particularly in mild-to-moderate cases. We sought to compare patient-reported stress urinary incontinence severity by pads per day with objective findings on standing cough test. We hypothesize that patient-reported pads per day often underestimates stress urinary incontinence severity. MATERIALS AND METHODS: We retrospectively reviewed our male stress urinary incontinence surgical database and identified 299 patients with self-reported mild-to-moderate stress urinary incontinence who were evaluated with standing cough test prior to surgical intervention between 2007 and 2019. Patients were evaluated with the Male Stress Incontinence Grading Scale for urinary leakage during a standing cough test. This test has been shown to reliably and accurately predict surgical success. Binary logistic regression analysis was used to identify parameters associated with stress urinary incontinence upgrading in a multivariable model. RESULTS: Among 299 patients with reported mild-to-moderate stress urinary incontinence, 101 (34%) were upgraded to severe stress urinary incontinence by standing cough test. Prior stress urinary incontinence surgery (OR 4.1, 95% CI 2.0-8.0, p < 0.0001) and radiation (OR 3.2, 95% CI 1.7-5.7, p < 0.0001) were significantly associated with Male Stress Incontinence Grading Scale upgrading in multivariable analysis. CONCLUSIONS: Roughly one-third of men who report mild-to-moderate stress urinary incontinence actually have severe incontinence observed on physical examination. All men being evaluated for stress urinary incontinence should undergo standing cough test to accurately grade incontinence severity and guide surgical management.

ABSTRACT

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.

ABSTRACT

PURPOSE: Non-muscle-invasive bladder cancer involving the prostatic urethra is associated with pathologic upstaging and shorter survival. We investigated the survival impact of prostatic urethral involvement in non-muscle-invasive patients who are not upstaged at cystectomy. METHODS: From 2000 to 2016, 177 male patients underwent cystectomy for high-risk non-muscle-invasive bladder cancer and remained pT1, pTis, or pTa, and N0 on final pathology; 63 (35.6%) patients had prostatic urethral involvement and 114 (64.4%) did not. Prostatic involvement was non-invasive (Ta or Tis) in 56 (88.9%) patients and superficially invasive (T1) in 7 (11.1%) patients. No patient had stromal invasion. Log-rank and Cox regression analyses were used to evaluate survival. RESULTS: Compared to patients without prostatic urethral involvement, patients with involvement were more likely to have received intravesical therapy (84.6% vs. 64.4%, p < 0.01), have multifocal tumor (90.8% vs. 51.7%, p < 0.01), and have positive urethral margins (7.7% vs. 0%, p < 0.01) and ureteral margins (18.5% vs. 5.1%, p < 0.01). Log-rank comparison showed inferior recurrence-free, cancer-specific, and overall survival in patients with prostatic involvement (p = 0.01, p = 0.03, p < 0.01). Patients with prostatic urethral involvement were more likely to experience recurrence in the urinary tract (p < 0.01). On Cox regression, prostatic urethral involvement was an independent predictor of overall mortality (HR = 2.08, p < 0.01). CONCLUSIONS: Prostatic urethral involvement is associated with inferior survival in patients who undergo cystectomy for non-muscle-invasive bladder cancer and remain pT1, pTis, or pTa on final pathology. Prostatic urethral involvement is thus an adverse pathologic feature independent of its association with upstaging.

ABSTRACT

OBJECTIVE: To investigate the impact of continent urinary diversion on readmissions and hospital costs in a nationally representative sample of radical cystectomies (RCs) performed in the USA. PATIENTS AND METHODS: The 2010-2014 Nationwide Readmissions Database was queried for patients with a diagnosis of bladder cancer who underwent RC. We identified patients undergoing continent (neobladder or continent cutaneous reservoir) or incontinent (ileal conduit) diversions. Multivariable logistic regression models were used to identify predictors of 90-day readmission, prolonged length of stay, and total hospital costs. RESULTS: Amongst 21 126 patients identified, 19 437 (92.0%) underwent incontinent diversion and 1 689 (8.0%) had a continent diversion created. Continent diversion patients were younger, healthier, and treated at high-volume metropolitan centres. Continent diversions resulted in fewer in-hospital complications (37.3% vs 42.5%, P = 0.02) but led to more 90-day readmissions (46.5% vs 39.6%, P = 0.004). In addition, continent diversion patients were more often readmitted for infectious complications (38.7% vs 29.4%, P = 0.004) and genitourinary complications (18.5% vs 13.0%, P = 0.01). On multivariable logistic regression, patients with a continent diversion were more likely to be readmitted within 90 days (odds ratio [OR] 1.55, 95% confidence interval [CI]: 1.28, 1.88) and have increased hospital costs during initial hospitalisation (OR 1.99, 95% CI: 1.52, 2.61). Continent diversion led to a $4 617 (American dollars) increase in initial hospital costs ($36 640 vs $32 023, P < 0.001), which was maintained at 30 days ($48 621 vs $44 231, P < 0.001) and at 90 days ($56 380 vs $52 820, P < 0.001). CONCLUSION: In a nationally representative sample of RCs performed in the USA, continent urinary diversion led to more frequent readmissions and increased hospital costs. Interventions designed to address specific outpatient issues with continent diversions can potentially lead to a significant decrease in readmissions and associated hospital costs.

ABSTRACT

PURPOSE: While retroperitoneal lymph node dissection (RPLND) is traditionally reserved for nonseminomatous germ cell tumors, recent efforts to reduce long-term toxicities of radiation and chemotherapy have turned attention to its application for testicular seminomas. Currently, RPLND is reserved for the post-chemotherapy for stage II testicular seminomas; we aimed to describe current utilization of RPNLD for testicular seminomas by stage and implications for survival. METHODS: A national sample of men diagnosed with stage IA/IB/IS/IIA/IIB/IIC testicular seminoma (1988-2013) was evaluated from SEER Program registries. Stage-specific utilization of RPLND was determined. Cox proportional hazards models, adjusted for age, race, and radiotherapy, evaluated overall (OS) and cancer-specific survival (CSS) for the RPLND cohort. Adjusted models assessed predictors of RPLND. RESULTS: A total of 17,681 men (mean age 38.1 years) with testicular seminoma were included with low utilization of RPLND for stage I disease (1.3% overall) and higher rates for stage II disease (10.6% overall). There were no appreciable trends over time. Patients receiving RPLND did not appear to have worse OS or CSS on adjusted stage-by-stage analysis. Higher stage disease (IIA-IIC) was associated with greater need for RPLND while radiotherapy was associated with decreased use [OR 0.40 (0.32-0.51), p < 0.001]. CONCLUSIONS: Utilization of RPLND for testicular seminomas in the post-chemotherapy setting has remained stable over a 25-year period. Patients undergoing RPLND are a higher risk cohort but stage-by-stage survival outcomes appeared comparable to men not undergoing RPLND. Upcoming trials implementing RPLND as a first-line modality for testicular seminoma or isolated retroperitoneal relapse will help better quantify relative recurrence and survival.

ABSTRACT

PURPOSE OF REVIEW: To explore the current state of using prostate-specific membrane antigen (PSMA)-targeted PET imaging to aid in the diagnosis of clinically significant prostate cancer. RECENT FINDINGS: Prostate-specific antigen screening remains controversial, as it is associated with the underdetection of clinically significant prostate cancer as well as the overdetection and subsequent overtreatment of clinically insignificant disease. A diagnostic test that can accurately assess the presence of clinically significant prostate cancer and avoid detection of low-risk tumors is needed. Multiparametric magnetic resonance imaging (mpMRI) can aid in the detection of clinically significant prostate cancer and can be used with fusion-based biopsy platforms to target biopsies to specific lesions. However, there are several limitations of mpMRI including a modest negative predictive value for high-grade cancer. PSMA-targeted PET imaging has shown promise as a noninvasive test to aid in the detection of clinically significant prostate cancer while providing anatomical information to guide targeted biopsies. PSMA-targeted PET in combination with mpMRI offers a higher degree of diagnostic accuracy for imaging localized prostate cancer than either modality alone. SUMMARY: PSMA-targeted PET imaging can aid in the identification of men with clinically significant prostate cancer. Further research is needed to determine the full potential of PSMA-targeted imaging in both the detection and treatment of localized prostate cancer.

ABSTRACT

PURPOSE OF REVIEW: Determining the metastatic viability of suspicious retroperitoneal nodes in testicular cancer with conventional imaging is challenging. The aim of this report is to review recent evidence in the utilization of novel imaging modalities to assess viable testicular cancer nodal metastases. RECENT EVIDENCE: Testicular germ cell tumors (TCGTs) follow a predictable lymphatic metastatic spread to the retroperitoneum. Accordingly, retroperitoneal imaging is critical in staging, assessing treatment response, and evaluating for recurrence. Conventional computed tomography (CT) imaging is effective in diagnosing pathologically enlarged lymph nodes but lacks the molecular information to determine if suspicious nodes harbor viable tumor. Positron emission tomography (PET) with the metabolic radiotracer 2-deoxy-2-[18F]fluoro-D-glucose (18F-FDG or FDG) has been shown to be useful in determining the presence of or absence of viable tumor after chemotherapy for seminoma, but its role with non-seminomatous germ cell tumors (NSGCTs) and other clinical scenarios is limited. Patients with residual masses after chemotherapy for NSGCT present a difficult challenge because surgical resection carries a high degree of morbidity despite many patients only harboring fibrosis on final pathology. Current imaging modalities are unable to effectively differentiate fibrosis from viable tumor on preoperative imaging. Novel molecular imaging techniques present promising opportunities to improve diagnosis in these patients. Novel imaging platforms have potential to improve the ability to determine viable nodal metastases regardless of size and structure but confirmatory studies are currently lacking.

ABSTRACT

INTRODUCTION: To improve care for patients after radical cystoprostatectomy (RCP), focus on survivorship issues such as sexual function needs to increase. Previous studies have demonstrated the burden of erectile dysfunction (ED) after RCP to be as high as 89%. AIM: To determine the rates of ED treatment use (phosphodiesterase type 5 inhibitors, injectable therapies, urethral suppositories, vacuum erection devices, and penile prosthetics) in patients with bladder cancer before and after RCP to better understand current patterns of care. METHODS: Men with bladder cancer undergoing RCP were identified in the MarketScan database (2010-2014). ED treatment use was assessed at baseline (during the 1 year before RCP) and at 6-month intervals (0-6, 7-12, 13-18, 19-24 months) after RCP. Multivariable logistic regression models were used to identify predictors of ED treatment use at 6-month intervals after RCP. OUTCOMES: ED treatment rates and predictors of ED treatment at 0-6, 7-12, 13-18, 19-24 month follow-up after RCP. RESULTS: At baseline, 6.5% of patients (77 of 1,176) used ED treatments. The rates of ED treatment use at 0 to 6, 7 to 12, 13 to 18, and 19 to 24 months after RCP were 15.2%, 12.7%, 8.1%, and 10.1% respectively. Phosphodiesterase type 5 inhibitors were the most commonly used treatment at all time points. In the multivariable model, predictors of ED treatment use at 0 to 6 months after RCP were age younger than 50 years (odds ratio [OR] = 3.17, 95% CI = 1.68-6.01), baseline ED treatment use (OR = 5.75, 95% CI = 3.08-10.72), neoadjuvant chemotherapy (OR = 1.72, 95% CI = 1.13-2.61), and neobladder diversion (OR = 2.40, 95% CI = 1.56-3.70). Baseline ED treatment use continued to be associated with ED treatment use at 6 to 12 months (OR = 5.63, 95% CI = 2.42-13.10) and 13 to 18 months (OR = 8.99, 95% CI = 3.05-26.51) after RCP. CLINICAL IMPLICATIONS: While the burden of ED following RCP is known to be high, overall ED treatment rates are low. These findings suggest either ED treatment is low priority for RCP patients or education about potential ED therapies may not be commonly discussed with patients following RCP. Urologists should consider discussing sexual function more frequently with their RCP patients. STRENGTHS & LIMITATIONS: Strengths include the use of a national claims database, which allows for longitudinal follow-up and detailed information on prescription medications and devices. Limitations include the lack of pathologic and oncologic outcomes data. CONCLUSION: ED treatment use after RCP is quite low. The strongest predictor of ED treatment use after RCP was baseline treatment use. These findings suggest ED treatment is a low priority for patients with RCP or education about potential ED therapies might not be commonly discussed with patients after RCP. Urologists should consider discussing sexual function more frequently with their patients undergoing RCP. Chappadi MR, Kates M, Sopko NA, et al.

ABSTRACT

BACKGROUND: The surgical treatment of urinary incontinence and erectile dysfunction by prosthetic devices has become part of urologic practice, although sparse data exist at a national level on readmissions and hospital costs. AIM: To assess causes and costs of early (≤30 days) and late (31-90 days) readmissions after implantation of penile prostheses (PPs), artificial urinary sphincters (AUSs), or PP + AUS. METHODS: Using the 2013 and 2014 US Nationwide Readmission Databases, sociodemographic characteristics, hospital costs, and causes of readmission were compared among PP, AUS and AUS + PP surgeries. Multivariable logistic regression models tested possible predictors of hospital readmission (early, late, and 90 days), increased hospital costs, and prolonged length of stay at initial hospitalization and readmission. OUTCOME: Outcomes were rates, causes, hospital costs, and predictive factors of early, late, and any 90-day readmissions. RESULTS: Of 3,620 patients, 2,626 (73%) had PP implantation, 920 (25%) had AUS implantation, and 74 (2%) underwent PP + AUS placement. In patients undergoing PP, AUS, or PP + AUS placement, 30-day (6.3% vs 7.9% vs <15.0%, P = .5) and 90-day (11.6% vs 12.8% vs <15.0%, P = .8) readmission rates were comparable. Early readmissions were more frequently caused by wound complications compared with late readmissions (10.9% vs <4%, P = .03). Multivariable models identified longer length of stay, Charlson Comorbidity Index score higher than 0, complicated diabetes, and discharge not to home as predictors of 90-day readmissions. Notably, hospital volume was not a predictor of early, late, or any 90-day readmissions. However, within the subset of high-volume hospitals, each additional procedure was associated with increased risk of late (odds ratio = 1.06, 95% CI = 1.03-1.09, P < .001) and 90-day (odds ratio = 1.03 95% CI = 1.02-1.05, P < .001) readmissions. AUS and PP + AUS surgeries had higher initial hospitalization costs (P < .001). A high hospital prosthetic volume decreased costs at initial hospitalization. Mechanical complications led to readmission of all patients receiving PP + AUS. CLINICAL IMPLICATIONS: High-volume hospitals showed a weaker association with increased initial hospitalization costs. Charlson Comorbidity Index, diabetes, and length of stay were predictors of 90-day readmission, showing that comorbidity status is important for surgical candidacy. STRENGTHS AND LIMITATIONS: This is the first study focusing on readmissions and costs after PP, AUS, and PP + AUS surgeries using a national database, which allows ascertainment of readmissions to hospitals that did not perform the initial surgery. Limitations are related to the limited geographic coverage of the database and lack of surgery- and surgeon-specific variables. CONCLUSIONS: Analysis of readmissions can provide better care for urologic prosthetic surgeries through better preoperative optimization, counseling, and resource allocation.

ABSTRACT

PURPOSE OF REVIEW: The aim of this review is to discuss how novel imaging modalities and molecular markers are shaping the definition of oligometastatic prostate cancer. RECENT FINDINGS: To effectively classify a patient as having oligometastatic prostate cancer, diagnostic tests must be sensitive enough to detect subtle sites of metastatic disease. Conventional imaging modalities can readily detect widespread polymetastatic disease but do not have the sensitivity necessary to reliably classify patients as oligometastatic. Molecular imaging using both metabolic- and molecularly-targeted radiotracers has demonstrated great promise in aiding in our ability to define the oligometastatic state. Perhaps the most promising data to date have been generated with radiotracers targeting prostate-specific membrane antigen. In addition, early studies are beginning to define biologic markers in the oligometastatic state that may be indicative of disease with minimal metastatic potential. SUMMARY: Recent developments in molecular imaging have allowed for improved detection of metastatic prostate cancer allowing for more accurate staging of patients with oligometastatic disease. Future development of biologic markers may assist in defining the oligometastatic state and determining prognosis.

ABSTRACT

PURPOSE: To our knowledge quality of life has not been evaluated in rigorous fashion in patients undergoing active surveillance for small renal masses. The prospective, multi-institutional DISSRM (Delayed Intervention and Surveillance for Small Renal Masses) Registry was opened on January 1, 2009, enrolling patients with cT1a (4.0 cm or less) small renal masses who elected primary intervention or active surveillance. MATERIALS AND METHODS: Patients were enrolled following a choice of active surveillance or primary intervention. The active surveillance protocol includes imaging every 4 to 6 months for 2 years and every 6 to 12 months thereafter. The SF12® quality of life questionnaire was completed at study enrollment, at 6 and 12 months, and annually thereafter. MCS (Mental Component Summary), PCS (Physical Component Summary) and overall score were evaluated among the groups and with time using ANOVA and linear regression mixed modeling. RESULTS: At 82 months among 3 institutions 539 patients were enrolled with a mean ± SD followup of 1.8 ± 1.7 years. Of the patients 254 were on active surveillance, 285 were on primary intervention and 21 were on active surveillance but crossed over to delayed intervention. A total of 1,497 questionnaires were completed. Total and PCS quality of life scores were better for primary intervention at enrollment through 5 years. There were generally no differences in MCS scores among the groups and there was a trend of improving scores with time. CONCLUSIONS: In a prospective registry of patients undergoing active surveillance or primary intervention for small renal masses those undergoing primary intervention had higher quality of life scores at baseline. This was due to a perceived benefit in the physical health domain, which persisted throughout followup. Mental health, which includes the domains of depression and anxiety, was not adversely affected while on active surveillance, and it improved with time after selecting a management strategy.

ABSTRACT

PURPOSE OF REVIEW: The purpose is to discuss current data on the utilization and outcomes of active surveillance for T1a renal masses. Specifically, to address which patients are optimal for active surveillance and how their outcomes differ from those undergoing immediate treatment. RECENT FINDINGS: Although nephron sparing surgery is the standard of care for small renal masses (SRMs), active surveillance is becoming a more popular intervention given the results of prospective studies revealing active surveillance to be safe and have excellent cancer-specific survival with intermediate follow-up. Older and sicker patients have competing risk of death from other causes when diagnosed with a SRM. SUMMARY: Active surveillance is becoming a more popular treatment modality for SRMs given the increasing number of incidental diagnoses and better understanding of their often indolent course. Active surveillance with delayed intervention is a well-tolerated treatment modality and appears to have the most benefit for those patients that are older with more comorbidities.

ABSTRACT

INTRODUCTION: Radiation cystitis with hematuria (RCH) is a potentially devastating complication after pelvic radiation. The cumulative incidence of RCH is debated, and certain severe manifestations may require hospital admission. We aimed to evaluate demographics and outcomes of patients hospitalized for RCH. METHODS: We performed a retrospective review of hospitalized patients with a primary or secondary diagnosis of RCH from 2016 to 2019 using the National Inpatient Sample. Our unit of analysis was inpatient encounters. Our primary outcome was inpatient mortality. Secondary outcomes included need for inpatient procedures, transfusion, length of stay (LOS), and cost of admission. We then performed multivariate analysis using either a logistic or linear regression to identify predictors of mortality and LOS. Cost was analyzed using a generalized linear model controlling for LOS. RESULTS: We identified 21,320 weighted cases of hospitalized patients with RCH. The average patient age was 75.4 years, with 84.7% male and 69.3% White. The median LOS was 4 days, and the median cost was $8767. The inpatient mortality rate was 1.3%. The only significant predictor for mortality was older age. The only significant predictor of both higher cost and longer LOS was an Elixhauser Comorbidity Score ≥ 3. CONCLUSIONS: RCH represents a significant burden to patients and the health care system, and we observed an increasing number of hospitalized patients over time. Additional research is needed to identify underlying causes of RCH and effective treatments for this sometimes-severe complication of pelvic radiation.

ABSTRACT

Prolonged ischemic priapism presents a treatment challenge given the difficulty in achieving detumescence and effects on sexual function. To evaluate current practice patterns, an open, web-based multi-institutional survey querying surgeons' experience with and perceived efficacy of tunneling maneuvers (corporoglanular tunneling and penoscrotal decompression), as well as impressions of erectile recovery, was administered to members of societies specializing in male genital surgery. Following distribution, 141 responses were received. Tunneling procedures were the favored first-line surgical intervention in the prolonged setting (99/139, 71.2% tunneling vs. 14/139, 10.1% implant, p < .001). Although respondents were more likely to have performed corporoglanular tunneling than penoscrotal decompression (124/138, 89.9% vs. 86/137, 62.8%, p < .001), penoscrotal decompression was perceived as more effective among those who had performed both (47.3% Very or Extremely Effective for penoscrotal decompression vs. 18.7% for corporoglanular tunneling; p < .001). Many respondents who had performed both tunneling procedures felt that most regained meaningful sexual function after either corporoglanular tunneling or penoscrotal decompression (33/75, 44.0% vs. 33/74, 44.6%, p = .942). While further patient-centered investigation is warranted, this study suggests that penoscrotal decompression may outperform corporoglanular tunneling for prolonged priapism, and that recovery of sexual function may be higher than previously thought after tunneling procedures.
