It's complicated: The relationship of non-narcotic medications and postoperative opioid use in radical cystectomy patients.

INTRODUCTION: The effect of individual non-narcotic analgesics in cystectomy enhanced recovery after surgery (ERAS) is unknown. Additionally, many non-narcotic medications are associated with side effects pertinent to the cystectomy population. To better understand the actual use and utility of these medications, we sought to characterize the association between non-narcotic medications and milligram morphine equivalent (MME) narcotic score during the postoperative inpatient stay. METHODS: We reviewed 260 consecutive ERAS cystectomy patients. The MME impact of non-narcotic compliance and cumulative dose of medication received was evaluated separately with general linear models. We also assessed relationship of non-narcotic compliance to patient reported pain score, length of stay (LOS), and time to return of bowel function (ROBF) and performed manual review of postoperative documentation to identify reasons for medication noncompliance. RESULTS: Compliance with postoperative acetaminophen, gabapentin, and ketorolac was low. There was an inverse relationship between ketorolac dose and MME on postoperative day 1 (-0.026 MME/mg; P = 0.004) and postoperative day 2 (-0.33 MME/mg; P < 0.001). Compliance with ketorolac was associated with lower MME on postoperative day 1 (26.1 MME v. 33.6 MME; P = 0.023). There were no such associations identified with gabapentin or acetaminophen. Gabapentin compliance was associated with earlier ROBF (3.7 days v. 4.3 days; P = 0.006). Ketorolac compliance was associated with lower pain score on POD1 (3.25 VAS v. 4.07 VAS; P = 0.019) and POD2 (3.05 VAS v. 3.85 VAS; P = 0.040) There was no association between medication compliance and LOS. The most common reasons identified for non-compliance with gabapentin and ketorolac were renal function concerns (38% and 40% respectively), bleeding concerns with ketorolac (20%) and concerns for neurologic adverse effect with gabapentin (16%). CONCLUSION: Compliance with non-narcotic medications in our ERAS cystectomy protocol was poor. There was a modest association with ketorolac and postoperative MME but no association with gabapentin or acetaminophen. Further study will clarify the role of these medications for cystectomy patients. Component specific analysis of protocolized care is valuable and may alter care pathways.

Persistent opioid and benzodiazepine use after radical cystectomy in enhanced recovery after surgery (ERAS) patients.

OBJECTIVES: Opioid use, misuse, and diversion is of paramount concern in the United States. Radical cystectomy is typically managed with some component of opioid pain control. We evaluated persistent opioid and benzodiazepine use after radical cystectomy and assessed the impact of their preoperative use on this outcome. We also explored associations between preoperative use and perioperative outcomes. METHODS AND MATERIALS: We used prospectively maintained data from our enhanced recovery after surgery (ERAS) cystectomy database and the Prescription Reporting with Immediate Medication Utilization Mapping (PRIMUM) database to identify controlled substance prescriptions for radical cystectomy patients. We separated patients by frequency of preoperative opioid and/or benzodiazepine prescriptions (0, 1, 2+) and used these cohorts to explore persistent use (prescription 3-12 months after surgery) alongside perioperative outcomes. RESULTS: Our cohort included 257 patients undergoing cystectomy at a single institution from 2017 to 2021. Preoperative opioid and benzodiazepine prescriptions were documented for 120 (46.7%) and 26 (10.1%) patients, respectively. Persistent opioid use was observed in 20 (14.6%) of opioid-naive patients (no prescriptions in 9 months prior to surgery) while 13 (19.7%) patients with 1 preoperative prescription and 28 (51.9%) patients with 2 or more preoperative prescriptions demonstrated persistent use. New persistent benzodiazepine use occurred in 6 (2.6%) patients. Overall persistent benzodiazepine use was present in 11 (4.3%) patients. In a multivariable model, preoperative opioid and benzodiazepine prescriptions were associated with persistent opioid use (P < 0.001; P = 0.027 respectively). No association was identified between preoperative opioid or benzodiazepine usage and perioperative outcomes including length of stay, return of bowel function, inpatient opioid usage, inpatient or discharge complications, readmissions, or emergency department visits. Inpatient pain scores were noted to be higher in patients with ≥ 2 preoperative opioid prescriptions (P = 0.037). CONCLUSIONS: Persistent opioid use was present in 23.7% of patients, with a new persistent use rate of 14.6%. Benzodiazepine use was less frequent than opioids, with a small number demonstrating new persistent use. Preoperative opioid and benzodiazepine use is associated with persistent opioid use postoperatively. Preoperative opioid and benzodiazepine use did not affect perioperative outcomes in our cohort.

Impact of dedicated renal enhanced recovery after surgery (RERAS) program on postoperative opioid consumption and evaluation of surgeon-specific compliance to the program.

INTRODUCTION AND OBJECTIVE: Enhanced Recovery After Surgery (ERAS) protocols have been increasingly applied to urologic surgeries such as cystectomy and prostatectomy, though research defining protocols and outcomes for renal ERAS programs (RERAS) for nephrectomy remains limited. We aim to assess perioperative outcomes following implementation of our RERAS protocol modified from ERAS society cystectomy guidelines, as well as describe compliance with protocol guidelines. METHODS: We performed a retrospective cohort analysis of 400 patients who underwent partial or radical nephrectomy between October 2017 and August 2020. RERAS protocol was initiated September 30, 2018, and patients were categorized into pre- and post-RERAS implementation cohorts based on surgery date. Perioperative outcomes including complications, 30-day readmissions, length of stay, and opioid consumption were compared across pre- and post-RERAS cohorts. Protocol compliance was reported based on adherence to program recommendations. RESULTS: Among 400 patients included in analysis, the pre-RERAS cohort included 133 patients and the post-RERAS cohort included 267 patients. There were no differences in overall complications (P = 0.354) and 30-day readmissions (P = 0.078). Length of stay (P < 0.001) and postoperative opioid consumption (P < 0.001) were significantly reduced post-RERAS. We observed an increase in compliance with RERAS recommendations over time (P< 0.001). CONCLUSION: RERAS implementation was associated with decreased length of stay and opioid usage, underscoring the benefits of program adoption in an era of opioid dependence and strained hospital capacity. Successful initiation of a RERAS protocol requires intentional organization and buy in from all providers involved.

Racial and Socioeconomic Disparities in MRI-Fusion Biopsy Utilization to Assess for Prostate Cancer.

OBJECTIVE: To evaluate whether racial disparities in MRI-Bx usage persisted after correction for socioeconomic, demographic, and clinical factors. METHODS: This is a retrospective cohort study of patients who received either MRI-Bx or systematic biopsy (SB) within a single academic medical center between January 2018 - June 2020. For each patient, socioeconomic variables including household income, education, percent below poverty, and unemployment were estimated using 2015 American Community Survey census-tract level data. Chi-square analysis was used to examine differences in clinical and demographic characteristics between the two groups. The Benjamini-Hochberg procedure was used to control false discovery rate (FDR) for multiple testing. RESULTS: Eighteen percent of Black men (53/295) received MRI-Bx while 41% (228/561) of white men received MRI-Bx. Patients coming from highly impoverished areas were less likely to receive MRI-Bx, 25% vs 75%, respectively. In multivariate analysis, race remained significantly different across MRI-Bx and SB groups. Clinical factors including family history, DRE, BMI, and prostate volume were not significantly different between patients receiving MRI-Bx and SB. CONCLUSION: Black men are less likely to receive MRI-Bx than white men, even after adjusting for clinical and socioeconomic characteristics. Further work is necessary to identify and study methods to increase equity in PCa diagnostic testing.

Surgeon-administered Transversus Abdominis Plane (TAP) Block is Associated With Decreased Opioid Usage and Length of Stay Following Radical Cystectomy.

OBJECTIVE: To study the effect of surgeon-administered Transversus Abdominis Plane block (sTAP) on opioid usage and length of stay (LOS). METHODS: Starting in April 2018, two surgeons at our institution gradually introduced sTAP for radical cystectomy (RC) patients. We performed a retrospective observational cohort analysis of RC patients catalogued in a prospectively maintained database using the Enhanced Recovery After Surgery Interactive Auditing System. Two surgeons adopted the sTAP block technique in April 2018. We included patients undergoing RC for bladder malignancy under Enhanced Recovery After Surgery protocol between January 2017 and August 2020. Primary outcomes included LOS, and postoperative day (POD) 0-3 total opioids consumption measured by morphine milligram equivalents (MME). Multivariable linear or logistic models evaluated the association of TAP with outcomes while controlling for potential confounders. RESULTS: Among 178 patients included in analysis, 84 patients underwent sTAP block and 94 did not. Multivariable analysis demonstrated significantly lower POD 0-3 total opioid usage (106.4 vs 192.2 MME, P = .004), and mean LOS (5.6 vs 7.7 days, P <.001) among the sTAP group. CONCLUSION: sTAP appears to be an effective adjunct to RC care associated with improved LOS, and POD 0-3 opioid consumption. Further studies are needed to optimize TAP block technique and anesthetic composition.

Genomic analysis of response to bacillus Calmette-Guérin (BCG) treatment in high-grade stage 1 bladder cancer patients.

BACKGROUND: Intravesical bacillus Calmette-Guérin (BCG) therapy is standard treatment for high-risk non-muscle invasive bladder cancer (NMIBC) but overall efficacy is low, and no reliable predictive biomarkers currently exist to refine patient selection. We performed genomic analysis on high-grade (HG) T1 NMIBCs to determine if response to therapy is predicted by certain mutational and/or expressional changes. METHODS: Patients with HG T1 NMIBC treated with induction BCG were stratified by response into durable and non-durable responders. Baseline tumor samples were subjected to targeted DNA sequencing and whole-exome RNAseq. Genomic variants differing significantly between response groups were analyzed using Ingenuity Pathway Analysis (IPA) software. Variant selection was refined to target potential biomarker candidates for responsiveness to BCG. RESULTS: Among 42 patients, the median follow-up was 51.7 months and 40.5% (n=17) were durable BCG responders. Deleterious mutations in the RNA sequence of JCHAIN, S100A7, CLEC2B, and ANXA10 were more common in non-durable responders. Mutations in MCL1 and MSH6 detected on targeted sequencing were more commonly found in durable responders. Of all deleterious DNA and RNA mutations identified, only MCL1 was significantly associated with longer recurrence free survival (RFS) (P=0.031). CONCLUSIONS: Differences in the genomic profiles of HG T1 NMIBC tumors exist between those who show durable response to BCG and those who do not. Using pathway analysis, those differences imply upregulation of several interconnected inflammatory pathways among responders. Specific variants identified here, namely MCL1, are candidates for further study and, if clinically validated, may serve as useful biomarkers in the future.

Racial Disparities in Prostate Specific Antigen Screening and Referral to Urology in a Large, Integrated Health Care System: A Retrospective Cohort Study.

PURPOSE: Contemporary trends and racial disparities in prostate cancer screening and referral to urology for prostate cancer risk are not well characterized, despite consensus that Black men are at higher risk for poor prostate cancer outcomes. The objective of this study was to characterize current racial disparities in prostate cancer screening and referral from primary care to urology for prostate cancer concern within our large, integrated health care system. MATERIALS AND METHODS: This retrospective cohort study used data from Atrium Health's enterprise data warehouse, which includes patient information from more than 900 care locations across North Carolina, South Carolina and Georgia. We included all men seen in the ambulatory or outpatient setting between 2014 and 2019 who were ≥40 years old. Clinical and demographic data were collected for all men, including age and race. Racial outcomes were reported for all groups with >2% representation in the population. Between-group comparisons were determined using chi-squared analysis, Wilcoxon rank sum testing and multivariable logistic regression, with significance defined as p <0.05. RESULTS: We observed a significant decrease in prostate specific antigen testing across all age and racial groups in a cohort of 606,985 men at Atrium Health, including 87,189 Black men, with an overall relative decline of 56%. As compared to White men, Black men were more likely to undergo prostate specific antigen testing (adjusted OR 1.24, 95% CI 1.22-1.26) and be referred to urology for prostate cancer (adjusted OR 1.94, 95% CI 1.75-2.16). CONCLUSIONS: There was a continued significant decline in prostate cancer screening between 2014 and 2019. Despite having modestly elevated odds of being screened for prostate cancer compared to White men, Black men are relatively underscreened when considering that those who undergo prostate specific antigen screening are more likely to be referred by primary care to urology for additional prostate cancer diagnostic evaluation.

Clinical Utility of Postneoadjuvant Chemotherapy Computerized Tomography for Muscle Invasive Urothelial Bladder Cancer.

INTRODUCTION: For muscle invasive bladder cancer, computerized tomography scans are often used before cystectomy to optimize surgical decision planning. The aim of this study is to evaluate the clinical value of postneoadjuvant chemotherapy computerized tomography in patients with localized bladder cancer before cystectomy. METHODS: All T2-3N0 patients with urothelial bladder cancer who completed cisplatin based neoadjuvant chemotherapy were retrospectively analyzed. On postneoadjuvant chemotherapy computerized tomography patients with tumor progression, nodal involvement, metastatic disease and noncancer findings were determined, and subsequent surgical decision making was evaluated. RESULTS: Of 79 cases 21.5% had a new finding on postneoadjuvant chemotherapy scan of which false-positive rates for nodal and metastatic disease were 100%. The frequency of novel findings on postneoadjuvant computerized tomography were 4 (5.1%) with tumor progression, 6 (7.6%) newly discovered enlarged nodes, 8 (10.1%) suspicious for distant metastases and 3 (3.8%) noncancer related conditions. Only 3.8% (3) had alterations in original cystectomy plans exclusively due to tumor progression and 100% of the cohort underwent cystectomy. Overall survival was not associated with new findings (3-year OS 77.4% vs 74%, p=0.473). Median time from postneoadjuvant chemotherapy scan to cystectomy was statistically delayed for patients with new radiographic findings vs those with consistent preneoadjuvant chemotherapy scans (29.5 vs 51 days; p=0.014). CONCLUSIONS: Compared to the preneoadjuvant chemotherapy scans, our data suggests that postneoadjuvant chemotherapy computerized tomography scans discover new findings in approximately 21.5% of cases, but this rarely changes preoperative plans, is not associated with overall survival and is frequently associated with false-positive results.

Association of 5-Alpha Reductase Inhibitor Use with Prostate Specific Antigen Level at the Time of Urology Referral in a Retrospective Cohort at a Large, Integrated Health Care System.

INTRODUCTION: 5-Alpha reductase inhibitor (5-ARI) use leads to a 50% decline in serum prostate specific antigen (PSA) without a concomitant decrease in prostate cancer (PCa) risk. We hypothesize that failure to account for the effect of 5-ARI use on serum PSA leads to increased PCa risk at urology referral among 5-ARI users. METHODS: This is a retrospective cohort study for the years 2018-2019. Atrium Health is a large, vertically integrated health system with over 900 care locations in North Carolina and South Carolina. Men ≥40 years old during 2018-2019 who had a PSA test performed were included. We determined differences in corrected serum PSA level at the time of referral to urology. 5-ARI users and nonusers were compared using the chi-square test, Student's t-test and gamma regression. RESULTS: From 2018-2019, there were 91,368 men who underwent PSA testing, including 2,939 5-ARI users. At referral, 5-ARI users had similar uncorrected median PSA (5.8 vs 5.6 ng/ml, p=0.05). After correcting for the effect of 5-ARIs on PSA, 5-ARI users had a median PSA of 11.6 ng/ml at urology referral, compared to 5.6 ng/ml in nonusers. CONCLUSIONS: Men taking 5-ARIs have higher corrected serum PSA at time of referral to urology. As the unadjusted PSA at referral to urology for PCa risk was similar between 5-ARI users and nonusers, this indicates that the effect of 5-ARI use on serum PSA levels is not routinely accounted for when assessing PCa risk.

Epidemiology and survival outcome of adult kidney, bladder, and prostate rhabdomyosarcoma: A SEER database analysis.

Rhabdomyosarcoma (RMS) is rare in adulthood, accounting for 2%-5% of adult soft tissue tumors, and less than 20% occur in genitourinary organs. Given its rarity, survival data on adult kidney, bladder, and prostate RMSs is limited. In this population-based analysis, we performed an analysis of all adult RMS cases reported in Surveillance, Epidemiology, and End Results (SEER) database to understand prognostic factors among kidney, bladder, and prostate RMS. A query of the SEER database was performed from 1973 to 2016 for patients >18 of age with RMS. The final cohort consisted of 14 kidney, 35 bladder, and 21 prostate RMS cases in the adult population. Demographic, treatment, and survival data were obtained. Analysis was performed using Fisher's exact test, survival analysis, and model. The median (range) age of diagnosis for adult bladder RMS was 65 years old (19-84) compared to 52.5 (28-68) and 42 (19-87) for kidney and prostate (p = 0.007). About 78.6% of patients underwent surgical intervention. Five-year overall survival (OS) for adult kidney, bladder, and prostate RMS are 17.1% (2.9-41.6%), 22.2% (9.4-38.4%), and 33.0 (12.8-55.0%), respectively. OS was not statistically associated with primary site (p = 0.209). On multivariable analysis, compared to adult bladder RMS, kidney RMS had a higher incidence of mortality (HR: 2.16, 95% CI 1.03-4.53, p = 0.041). Incidence of mortality from prostate RMS was not significantly different from bladder RMS (HR: 0.70, 95% CI 0.30-1.65, p = 0.411). Extent of disease (HR: 5.17, 95% CI 2.09-12.79, p < 0.001) and older age (HR 1.03, 95% CI 1.01-1.04, p = 0.002) were adverse prognostic factors for OS. Overall survival at 5 years for adult kidney, bladder, and prostate RMS is poor. Localized disease and younger age are prognostic factors for improved outcomes in adult RMS. Hence, early diagnosis and intervention appear paramount to improved survival for this rare malignancy in adulthood.

Implementation of a Dedicated Enhanced Recovery after Surgery (ERAS) Program for Radical Cystectomy Patients is Associated With Decreased Postoperative Inpatient Opioid Usage and Pain Scores.

OBJECTIVE: To measure differences in post-operative opioid usage and pain scores between pre- and post-Enhanced Recovery after Surgery (ERAS) radical cystectomy (RC) patients in an effort to optimize outcomes. STUDY DESIGN: We performed a retrospective cohort study from a single institution from January 1, 2015 to July 31, 2018 among 86 and 108 pre- and post-ERAS RC patients. The primary endpoints were total mean opioid usage (morphine equivalent daily dosing or MEDD) and mean pain scores (Visual Analog Scale) on postoperative days (POD) 1-3. Secondary endpoints were number of opioid pills prescribed at discharge and within 30 days of discharge. Multivariable model selection was carried out with forward selection and backward elimination to identify variables associated with key outcomes. RESULTS: Total mean usage of opioids and mean pain scores were significantly lower in post-ERAS vs pre-ERAS patients across POD 1-3, respectively (32.90 MEDD vs 99.86 MEDD, P ≤ .001; 3.51 vs 4.17, P = .003). The median number of opioid pills prescribed at discharge was significantly lower in the post-ERAS group compared to pre-ERAS (30 pills vs 45 pills, P = .046) as well as the median number opioid pills prescribed within 30 days of discharge (40 pills vs 50 pills, P = .001). CONCLUSION: Our study suggests that a dedicated ERAS protocol following RC might be superior to traditional, non-ERAS methods in reducing postoperative opioid use and pain scores.

Postchemotherapy surgery for germ cell tumors--what have we learned in 35 years?

Postchemotherapy surgery for advanced testicular cancer has evolved over the last couple of decades. Patients with nonseminomatous germ cell tumors and residual retroperitoneal mass ≥1 cm should undergo postchemotherapy retroperitoneal lymph node dissection (RPLND). For seminoma, RPLND is considered in those patients with masses ≥3 cm that are also positron emission tomography positive. Masses that occur outside of the retroperitoneum should be completely resected with the possible exception of bilateral lung masses when resection of the first mass shows necrosis. The role of surgery in patients with extragonadal germ cell tumors is most vital in those with primary mediastinal nonseminomatous germ cell tumors. Importantly, patient selection, surgical planning, and consideration of referral to centers with this expertise are important to optimize success.

Neoadjuvant and adjuvant chemotherapy approaches for invasive bladder cancer.

Deeply invasive bladder cancer, representing approximately 20% of incident cases, is cured by radical cystectomy or radiotherapy in less than 50% of cases. In an effort to improve cure rates, based on objective response rates in metastatic disease of 40%-70% from combination chemotherapy regimens, systemic chemotherapy has been incorporated into programs of definitive treatment for this disease. Several randomized trials and a meta-analysis have confirmed a survival benefit from neoadjuvant chemotherapy followed by definitive local treatment, reflecting both median survival figures and cure rates. Despite several promising phase II trials, no randomized trial of classical adjuvant chemotherapy for bladder cancer has demonstrated an overall survival benefit, despite increments in disease-free survival. Molecular prognostication has been studied in an effort to improve the utility of systemic therapy for invasive non-metastatic bladder cancer, but randomized trials have not shown associated survival benefit. Despite level 1 evidence of a survival benefit from neoadjuvant MVAC (methotrexate, vinblastine, doxorubicin [Adriamycin], cisplatin) or cisplatin, methotrexate, and vinblastine (CMV) chemotherapy, more than 50% of incident cases do not receive such treatment.

Proteomic assays for the detection of urothelial cancer.

Bladder cancer is one of the most expensive cancers from diagnosis to death of the patient due to life-long surveillance involving upper tract imaging, urinary cytology, and cystoscopy. Cytology has been historically used in conjunction with cystoscopy to help detect disease that may be missed by routine cystoscopy (e.g., carcinoma in situ and upper tract disease). Urine cytology is highly cytopathologist dependent and has reasonable sensitivity for detecting high grade disease. However, its sensitivity drops precipitously with regard to well-differentiated low grade cancers. Intensive investigations have been undertaken using proteomics to find an alternative to cystoscopy and cytology. Urine proteomic markers currently evaluated critically in the literature include bladder tumor antigen, nuclear matrix protein 22, BLCA-4, hyaluronic acid, hyaluronidase, cytokeratin 8, cytokeratin 18, cytokeratin 19, tissue polypeptide antigen, and tissue polypeptide-specific antigen. Markers used as alternatives to cystoscopy must be accurate with high sensitivity and specificity, cost effective for life-long surveillance, and minimally invasive to minimize the burden to the patient. To date, no proteomic marker has been developed that can replace cystoscopy for the detection of bladder cancer. However, several urinary markers appear to have higher sensitivity albeit lower specificity than cytology and can be used to supplement cystoscopy. Some of those markers are herein described in this chapter. By defining and characterizing the current state of the art in protein based markers, we are poised to evaluate and benchmark newly discovered protein biomarkers that will be isolated through new proteomics based investigations of urine.

Association between lymph node density and disease specific survival in patients with penile cancer.

PURPOSE: We assessed the value of lymph node density for predicting disease specific survival after lymphadenectomy for penile cancer. MATERIALS AND METHODS: Data were collected retrospectively in 75 and prospectively in 88 consecutive patients with squamous cell carcinoma of the penis treated at M. D. Anderson Cancer Center between 1979 and 2007. We identified 45 patients with penile cancer and nodal metastasis who underwent lymphadenectomy with curative intent. Lymph node density was analyzed as a categorical variable by grouping patients into 2 or 3 categories based on equal percents. We explored the prognostic value of lymph node density for predicting disease specific survival in this cohort. RESULTS: Median followup was 23.7 months in all patients. By the time of analysis 22 patients had died, including 18 (82%) of penile cancer and 4 (18%) of other causes. Median lymph node density in patients alive or dead of other causes was 3.4% (IQR 2.9-5.9) compared to 43.3% (IQR 15.6-80) in those dead of disease (p <0.001). Median lymph node density in all patients was 6.7%. Estimated 5-year disease specific survival in patients with lymph node density 6.7% or less was significantly better than that in patients with lymph node density greater than 6.7% (91.2%, 95% CI 53.9-98.8 vs 23.3%, 95% CI 7.0-45.1, p <0.001). In models comparing lymph node density to known prognostic features lymph node density remained statistically significant, while the other factors were no longer statistically associated with disease specific survival. CONCLUSIONS: Lymph node density proved to be a significantly better prognosticator of disease specific survival than the current TNM nodal staging system in patients with penile cancer and nodal involvement. Further independent validation is required to determine the clinical usefulness of lymph node density in this patient population.

Urinary markers in screening patients with hematuria.

Hematuria is a common presenting symptom of urothelial malignancy. Although conventional urine analysis is very sensitive in detecting the presence of hematuria, it is not specific in detecting bladder cancer or other urinary-tract cancers. The noninvasive urinary tests NMP22 and UroVysion have been approved by the U.S. Food and Drug Administration for bladder cancer screening. These tests have better sensitivity than cytology for detecting bladder cancer in patients who present with hematuria. The positive predictive values of both tests increase in individuals with hematuria who have risk factors for bladder cancer. Evaluating hematuria with sensitive markers, such as NMP22 and UroVysion, in high-risk populations offers an opportunity to develop effective strategies for bladder cancer screening.

The use of erythropoietin in patients undergoing radical prostatectomy: effects on hematocrit, transfusion rates and quality of life.

OBJECTIVE: It was the aim of this study to prospectively study the effects on hematocrit levels, transfusion rates and quality of life (QOL) indices in men preoperatively supplemented with recombinant erythropoietin (rEPO) undergoing radical prostatectomy for clinically localized prostate cancer. METHODS: Thirty men undergoing radical prostatectomy were randomized either to receive rEPO (n=25) or to serve as controls (n=25). Outcome measurements obtained preoperatively, as well as 10 days and 6 weeks postoperatively included serum hematocrit levels, transfusion rates and QOL indices (using SF-12 validated questionnaires). RESULTS: The rEPO group had a significant increase in preoperative hematocrit (median increase=4 points; p=0.002). Although there were no significant differences in hematocrit at 10 days, the rEPO had a significantly higher hematocrit value at 6 weeks (p=0.0086). No differences were observed in transfusions rates between groups (4% in each group). SF-12 mental and SF-12 physical scores were not different between the two groups at any time point. CONCLUSION: Preoperative administration of rEPO significantly increases preoperative and postoperative hematocrit levels. However, no differences were observed with regard to transfusion rates or postoperative QOL indices despite these higher hematocrit values.

Rare cause of ureteral obstruction.

This report presents bilateral ureteral obstruction due to possible ureteritis in a bone marrow transplant patient with resurgence of BK virus after hemorrhagic cystitis. This is believed to be the first description of this type of ureteral obstruction. The presented case includes the management plan.
