Admission Rates, Healthcare Utilization, and Inpatient Cost of Radiation Cystitis in the United States.

OBJECTIVE: To assess the incidence, cumulative healthcare burden, and financial impact of inpatient admissions for radiation cystitis (RC), while exploring practice differences in RC management between teaching and nonteaching hospitals. METHODS: We focused on 19,613 patients with a diagnosis of RC within the National Inpatient Sample (NIS) from 2008 to 2014. ICD-9 diagnosis and procedure codes were used. Complex-survey procedures were used to study the descriptive characteristics of RC patients and the procedures received during admission, stratified by hospital teaching status. Inflation-adjusted cost and cumulative annual cost were calculated for the study period. Multivariable logistic regression was used to study the impact of teaching status on the high total cost of admission. RESULTS: Median age was 76 (interquartile range 67-82) years. Most of the patients were males (73%; P < .001). 59,571 (61%) patients received at least one procedure, of which, 24,816 (25.5%) received more than one procedure. Median length of stay was 5days (interquartile range 2-9). Female patients and patients with a higher comorbidity score were more frequently treated at teaching hospitals. A higher proportion of patients received a procedure at a teaching hospital (64% vs 59%; P < .001). The inflation-adjusted cost was 9207 USD and was higher in teaching hospitals. The cumulative cost of inpatient treatment of RC was 63.5 million USD per year and 952.2 million USD over the study period. CONCLUSION: The incidence of RC-associated admissions is rising in the US. This disease is a major burden to US healthcare. The awareness of the inpatient economic burden and healthcare utilization associated with RC may have funding implications.

Impact of lymphovascular invasion on survival in surgically treated upper tract urothelial carcinoma: a nationwide analysis.

OBJECTIVES: To assess the prognostic ability of lymphovascular invasion (LVI) in upper tract urothelial carcinoma (UTUC) as a predictor of overall survival (OS) using a large North American cohort. PATIENTS AND METHODS: Our cohort included 5940 patients with clinical M0 UTUC who underwent a radical nephroureterectomy (RNU), between 2010 and 2016, within the National Cancer Database. The main variable of interest was LVI status, and its interaction with pathological nodal (pN) status. Kaplan-Meier curves were used to depict the OS also stratifying patients on LVI status. Cox regression analysis tested the impact of LVI status on OS after accounting for the available covariates. RESULTS: The median (interquartile range [IQR]) age at diagnosis was 71 (63-78) years and most patients had pathological T1 stage disease (48.6%). Nodal status was pN0, pN1 and pNx in 45.8%, 6.3% and 47.9%, respectively. Overall, 22.1% had LVI. The median (IQR) follow-up time was 32.6 (16.0-53.3) months. At the 5-year postoperative follow-up, the estimated OS rate was 28% in patients with LVI vs 66% in those without LVI (P < 0.001). When patients were stratified based on nodal status those rates were 32% vs 68% in pN0 patients (P < 0.001), 23% vs 30% in pN1 patients (P = 0.8), and 28% vs 65% in pNx patients (P < 0.001). On multivariable analysis, the presence of LVI was associated with less favourable OS (hazard ratio 1.79, 95% confidence interval 1.60-1.99; P < 0.001). CONCLUSION: Our study assessed the impact of LVI on OS in patients with UTUC in a large North American nationwide cohort. Our series, as the largest to date, indicate that LVI is associated with less favourable survival outcomes in patients with UTUC after RNU, and this variable could be used in counselling patients about their prognosis and might be a useful tool for future trials to risk-stratify patients.

Assessing the impact of lymphovascular invasion on overall survival in surgically treated renal cell carcinoma patients: A nationwide cohort analysis.

INTRODUCTION: Lymph-vascular invasion (LVI) is recognized as an adverse pathological feature in patients with renal cell carcinoma (RCC). However, its impact on overall survival (OS) is not clear and scarcely addressed in the literature. We aimed to assess the prognostic ability of LVI as a predictor of OS in RCC patients using a large, North American cohort. METHODS: We included 95,783 cM0 RCC patients, diagnosed between 2010 and 2015, who underwent partial or radical nephrectomy within the National Cancer Database. Kaplan-Meier curves and log-rank tests were used to depict and compare survival curves. Cox regression analysis tested the impact of LVI on OS, after adjusting for all available confounders. RESULTS: Mean age (SD) was 59 (12), and most patients had pT1 stage (72.2%). Nodal status was pN0, pN1, and pNx, in 14.5%, 2.3%, and 83.3%, respectively. Overall, 9.0% of patients had LVI. The mean (SD) follow-up of the cohort was 39 months (24). At 5 years, OS was 65% in patients with LVI vs. 86% in patients without LVI (p<.0001). When patients were stratified based on nodal stage, these rates were 64% vs. 78% in pN0 patients, 31% vs. 41% in pN1 patients, and 69% vs. 87% in pNx patients (all P < 0.001). On multivariable analysis, and in comparison to patients without LVI, those with LVI had 1.37- (P < 0.001), 1.18- (P = 0.068), and 1.53-fold (P < 0.001) greater risk of death, when also harboring pN0, pN1, and pNx disease, respectively. CONCLUSIONS: Our findings are the first, to our best knowledge, to illustrate the clear detrimental impact of LVI on OS in surgically treated RCC patients. These findings might be useful in postoperative patient counseling and need to be accounted for when designing future clinical trials.

Temporal and Racial Trends in Prostate-specific Antigen Screening for U.S. Men With a Family History of Prostate Cancer.

INTRODUCTION: Limited data exist on trends in PSA screening in men with a family history of prostate cancer. The aims of our study were to (1) study age-stratified temporal trends in PSA screening from 2000-2018 for men with a family history of prostate cancer and Black men with a family history of prostate cancer, and (2) identify determinants associated with receipt of PSA screening in the aforementioned groups. METHODS: We identified men aged ≥40 years without a prior history of prostate cancer using data from National Health Interview Survey 2000-2018 who self-reported PSA testing in the last 12 months. Age-stratified temporal trends and weighted multivariable logistic regression analyses were assessed. RESULTS: PSA screening increased for men with a family history of prostate cancer between National Health Interview Survey 2000 (28.9%) and 2005 (41.9%), with stable rates for the following years. Black men with a family history of prostate cancer showed no significant change in PSA screening rates regardless of age. Controlling for sociodemographics and access to health care provider, younger age (40-54) and later survey years (2013-2018) were associated with a lower likelihood of PSA screening overall and for Black men, but not for those with a positive family history. CONCLUSIONS: Data from a nationally representative study of U.S. men indicated that the annual PSA screening rates for men with a family history of prostate cancer was higher than reported for the overall male population. We believe this represents the first study on trends and determinants of PSA screening in U.S. men with a family history of prostate cancer.

Who Is Shaping the Future of Academic Urology? A Descriptive Analysis of Residency Program Directors.

OBJECTIVE: To characterize the demographics, educational background, and scholarly characteristics of current urology residency program directors (PDs). METHODS: Urology programs were identified by the listing on the "Accredited US Urology Programs" section of American Urological Association website as of October 2021. Demographics and academic data were collected via publicly available department website and Google search engine. Metrics obtained included years of service as PD from time of appointment, sex, medical school/residency/fellowship, all-time H-index, dual degrees obtained, and professorial ranking. RESULTS: One hundred and forty-seven accredited urological residencies were reviewed; every PD was included. The majority were male (78%) and fellowship trained (68%). Women represented only 22% of PDs. The median active time served as PD, as of 11/2021, was 4years (IQR: 2-7). Forty (28%) were faculty at the same program they completed their residency. The median all-time H-index was 12 (IQR: 7-19; range 1-61). Twelve PDs also served as chair of their department. CONCLUSION: The vast majority of PDs are male, fellowship trained, and have served for less than 5years. Future studies are necessary to follow the trends of representation in leaders of urology residency programs.

Impact of preexisting opioid dependence on morbidity, length of stay, and inpatient cost of urological oncological surgery.

OBJECTIVES: To determine the incidence of preexisting opioid dependence in patients undergoing elective urological oncological surgery. In addition, to quantify the impact of preexisting opioid dependence on outcomes and cost of common urologic oncological procedures at a national level in the USA. METHODS: We used the National Inpatient Sample (NIS) to study 1,609,948 admissions for elective partial/radical nephrectomy, radical prostatectomy, and cystectomy procedures. Trends of preexisting opioid dependence were studied over 2003-2014. We use multivariable-adjusted analysis to compare opioid-dependent patients to those without opioid dependence (reference group) in terms of outcomes, namely major complications, length of stay (LOS), and total cost. RESULTS: The incidence of opioid dependence steadily increased from 0.6 per 1000 patients in 2003 to 2 per 1000 in 2014. Opioid-dependent patients had a significantly higher rate of major complications (18 vs 10%; p < 0.001) and longer LOS (4 days (IQR 2-7) vs 2 days (IQR 1-4); p < 0.001), when compared to the non-opioid-dependent counterparts. Opioid dependence also increased the overall cost by 48% (adjusted median cost $18,290 [IQR 12,549-27,715] vs. $12,383 [IQR 9225-17,494] in non-opioid-dependent, p < 0.001). Multivariable analysis confirmed the independent association of preexisting opioid dependence with major complications, length of stay in 4th quartile, and total cost in 4th quartile. CONCLUSIONS: The incidence of preexisting opioid dependence before elective urological oncology is increasing and is associated with adverse outcomes after surgery. There is a need to further understand the challenges associated with opioid dependence before surgery and identify and optimize these patients to improve outcomes.

Time to second biochemical recurrence as a prognostic indicator in postprostatectomy patients who undergo salvage radiation therapy: An RTOG 9601 based post hoc analysis.

INTRODUCTION AND OBJECTIVE: The prognostic significance of a "second" biochemical recurrence (sBCR) after salvage radiation therapy (sRT) with/without hormonal therapy following primary radical prostatectomy in men with prostate cancer has not been examined. We hypothesized that a shorter time to sBCR will be associated with worse cancer control outcomes. METHODS: The RTOG 9601 study included 760 patients with tumor stage pT2/T3, pN0, who had either persistently elevated prostate-specific antigen (PSA) postradical prostatectomy or developed subsequent biochemical recurrence with PSA levels between 0.2 and 4.0 ng/ml. All patients received sRT (with or without 2 years of Bicalutamide) from 1998 to 2015. For our study, we focused on 421 patients who had sBCR after sRT-which was defined as a PSA increase of at least 0.3 ng/ml over the first nadir. Patients were divided into two categories: early sBCR (n = 210) and late sBCR (n = 211) using median time to sBCR (3.51 years). All patients who experienced sBCR received salvage hormonal therapy. Competing-risk analysis was used to examine the impact of early versus late sBCR on prostate cancer specific mortality (CSM), after accounting for available covariates. RESULTS: The majority of patients were age 60 years or older (75.8%), had pT3 disease (74.8%), and Gleason score 7 (75.2%). Overall, 13.8% had persistent PSA initially after surgery. At 10 years, starting at the time of sBCR, CSM rate was 31.3% in the early sBCR group versus 20.0% in the late sBCR group. In competing-risk analysis, time to sBCR was an independent predictor of CSM, where patients with early sBCR had 1.7-fold higher CSM risk (p = 0.026) than their counterparts with late sBCR. CONCLUSIONS: Time to sBCR after sRT (with or without concomitant Bicalutamide) is a significant predictor of CSM following initial radical prostatectomy. This information can be used to guide subsequent treatments, and to counsel patients.

Appropriateness Criteria for Ureteral Stent Omission following Ureteroscopy for Urinary Stone Disease.

Objective: To bridge the gap between evidence and clinical judgement, we defined scenarios appropriate for ureteral stent omission after uncomplicated ureteroscopy (URS) using the RAND/UCLA Appropriateness Method (RAM). We retrospectively assessed rates of appropriate stent omission, with the goal to implement these criteria in clinical practice. Methods: A panel of 15 urologists from the Michigan Urological Surgery Improvement Collaborative (MUSIC) met to define uncomplicated URS and the variables that influence stent omission decision-making. Over two rounds, they scored clinical scenarios for Appropriateness Criteria (AC) for stent omission based on a combination of variables. AC were defined by median scores: 1 to 3 (inappropriate), 4 to 6 (uncertain), and 7 to 9 (appropriate). Multivariable analysis determined the association of each variable with AC scores. Uncomplicated URS cases in the MUSIC registry were assigned AC scores and stenting rates assessed. Results: Seven variables affecting stent decision-making were identified. Of the 144 scenarios, 26 (18%) were appropriate, 88 (61%) inappropriate, and 30 (21%) uncertain for stent omission. Most scenarios appropriate for omission were pre-stented (81%). Scenarios with ureteral access sheath or stones >10mm were only appropriate if pre-stented. Stenting rates of 5,181 URS cases correlated with AC scores. Stents were placed in 61% of cases appropriate for omission (practice range, 25% to 98%). Conclusion: We defined objective variables and AC for stent omission following uncomplicated URS. AC scores correlated with stenting rates but there was substantial practice variation. Our findings demonstrate that the appropriate use of stent omission is underutilized.

Risk-Based Assessment Of the Impact Of Intravesical Therapy on Recurrence-Free Survival Rate Following Resection of Suspected Low-grade, Non-muscle-invasive Bladder Cancer (NMIBC): A Southwest Oncology Groups (SWOG) S0337 Posthoc Analysis.

BACKGROUND: Nonmuscle invasive bladder cancer (NMIBC) has an elevated risk of recurrence, and immediate postresection intravesical instillation of chemotherapy (IVC) significantly reduces the risk of recurrence. Questions remain about which subpopulation may maximally benefit from IVC. Our aim was to develop risk groups based on recurrence risk in NMIBC, and then evaluate the impact of a single, postoperative instillation of IVC on the subsequent risk of recurrence for each risk group. MATERIAL AND METHODS: Using the SWOG S0337 trial cohort, we performed a posthoc analysis of 345 patients who were diagnosed with suspected low-grade NMIBC, underwent transurethral resection of the bladder tumor (TURBT), and received post-operative IVC (gemcitabine vs. saline). Using regression tree analysis, the regression tree stratified patients based on their risk of recurrence into low-risk - single tumor and aged < 57 years, intermediate-risk - single tumor and aged ≥ 57 years, and high-risk - multiple tumors. We used Cox proportional hazard models to test the impact of recurrence-free rate, and after adjustment to available covariates. RESULTS: Median age of the cohort was 66.5 (IQR: 59.7-75.8 years) with 85% of patients being males. Median overall follow-up time was 3.07 years (IQR: 0.75-4.01 years). When testing the impact of treatment in each risk group separately, we found that patients in the intermediate-risk treated with gemcitabine had a 24-month recurrence free rate of 77% (95% CI: 68%-86%) vs. 59% (95% CI: 49%-70%) in the saline group. This survival difference was confirmed on multivariable analysis (hazard ratio: 0.39, 95% CI: 23%-66%, P < 0.001). This group represented 53% of our cohort. Conversely, we did not observe a significant difference in recurrence-free survival among patients in the low- (P = 0.7) and high-risk (P = 0.4) groups. CONCLUSION: Our findings indicate that older patients with a single tumor of suspected low-grade NMIBC at TURBT maximally benefit from immediate postresection IVC (gemcitabine).

Benefit of lymph node dissection in cN+ patients in the treatment of upper tract urothelial carcinoma: Analysis of NCDB registry.

OBJECTIVES: The benefits of lymph node dissection (LND) in surgically treated upper tract urothelial carcinoma (UTUC) patients who present with clinically positive nodes at diagnosis remain unclear. The aim of this study was to assess survival differences in cN+ patients who underwent radical nephroureterectomy (RNU) with LND vs. without LND. METHODS: The National Cancer Database was used to identify a total number of 423 cN+ patients from 2004 to 2016 with UTUC that underwent RNU. Of the 423 patients, 310 received LND. Kaplan-Meier (KM) plots were used to estimate survival in cN+ patients who received RNU with LND vs. without. Cox proportional hazards regression tested the impact of LND status on overall survival (OS) after adjusting for all available covariates. RESULTS: Median age of the patient population was 68 years (IQR 61-76), and 56.74% were male. Median follow-up was 1.8 years (IQR 0.9-3.5). For the entire cohort, the 2-year OS rate was 51.8%, and it was 52.1% vs. 51.1% in patients who underwent LND vs. not (log-rank p-value=0.2). On multivariable analysis, performing LND had no statistically significant impact on OS (HR 0.93 95%CI 0.696-1.235, P = 0.9). Repeating the analysis in patients who had exclusively cN1 (HR 0.76 95%CI 0.469-1.223, P = 0.26) or cN2/3 (HR 0.844 95%CI 0.556-1.28, P = 0.43) disease also failed to demonstrate a significant impact of LND on survival. CONCLUSION: In cN+ patients with UTUC, performing LND in addition to RNU at any clinical stage does not seem to have a significant impact on OS.

Topical anesthetics for pediatric laser treatment.

Topical anesthetic agent causes transient insensibility to pain in a limited area of skin, and provides effective anesthesia in a short onset time, short duration, with seldom local or systemic side effects on intact skin and is simple to use. Topical formulations may offer significant benefits for prevention of procedural pain. Currently, they are considered to be the most effective anesthesia for laser treatments. Unfortunately, there is no standard anesthetic technique for this procedure. Lasers are being widely used in numerous dermatological and esthetics treatments in childhood. The advancement of new knowledge in laser technology have contributed to the development of new lasers that are commonly used in a pediatric population, such as Pulsed Dye, Carbon-dioxide and Nd:YAG laser. The most commonly used topical anesthetics in young patients for minimally or moderately painful laser cutaneous procedures are Lidocaine, Prilocaine, Tetracaine gel and combinations thereof.

Comparison of ketamine and ketofol for deep sedation and analgesia in children undergoing laser procedure.

The aim of our study was to research and evaluate cardiovascular and respiratory stability, clinical efficacy, and safety of two different anesthetic agents in pediatric patients who underwent Pulse dye (wavelength 595 nm, pulse duration 0-40 ms, power 0-40 J) and CO2 (wavelength 10,600 nm, intensity-fraxel mod with SX index 4 to 8, power 0-30 W) laser procedure. This prospective non-blinded study included 203 pediatric patients ASA I-II, aged between 1 month and 12 years who underwent short-term procedural sedation and analgesia for the laser procedure. After oral premedication with midazolam, 103 children were analgo-sedated with ketamine and fentanyl (K group) and 100 with ketofol and fentanyl (KT group). Vital signs, applied drug doses, pulse oximetry, and parental satisfaction questionnaire were used to compare these two groups. Statistical differences were tested using Student's t test, Mann-Whitney U test, chi-square test, and Fisher's exact test. Receiver operating characteristic (ROC) curve analysis was used to assess the cut-off value of the duration of anesthesia predicting apnea. Tachycardia was recorded in a significantly higher number of patients who received ketamine as the anesthetic agent (35.9 vs. 3% respectively). Hypertension was also significantly more frequent in patients who received ketamine in comparison with patients who received ketofol (25.2 vs. 3%). Laryngospasm was not observed in both examined groups. There was no statistically significant difference between groups in satisfaction of parents and doctors. Apnea and respiratory depression occurred significantly more frequent in ketofol than in ketamine group (12 vs. 0.97% and 13 vs. 0%). Based on ROC analysis for apnea, we found a significantly higher number of patients with apnea in the ketofol group when duration of anesthesia was longer than 17 min. Our study has shown that ketofol is more comfortable than ketamine in short-term laser procedures in children, causing less hemodynamic alteration with mild respiratory depression and less post-procedural adverse events.

[Cystic changes in the neck in children]. / Cistne promene na vratu kod dece.

The treatment of cystic neck lesions in 105 patients hospitalized in our institution over last 5 years was analyzed retrospectively in this study. The most frequent lesion was medial cyst of the neck, manifesting in almost 50% of patients. Lateral cysts, dermoid cysts and cystic hygroma were found in 25%, 10% and 8%, respectively. Although congenital in origin, clinical manifestation of medial cervical cyst occurs usually in preschool and particularly in school period (average 6 year). Cysts of the neck were present in male and female equally. The most frequent complication in early postoperative period was hematoma. During three-year follow-up there was neither recurrence nor malignant alteration.
