RESUMEN
INTRODUCTION: The objective of this study was to determine effects of adjuvant chemotherapy (AC) on survival outcomes compared to surgery alone without AC for upper tract urothelial carcinoma (UTUC) patients with variant histology (VH). METHODS: We conducted a systematic review and meta-analysis of studies investigating AC for UTUC in Medline, Embase, the Cochrane Library up to January 2023. Population, intervention, comparator, and outcome were UTUC patients with VH, radical nephroureterectomy with AC, radical nephroureterectomy only, and oncological survival, respectively. RESULTS: Four retrospective studies were included. Regarding overall survival (OS), the pooled hazard ratio was 0.61 (95% confidence interval: 0.42-0.87; p = 0.007) across two studies. Regarding cancer-specific survival (CSS), the pooled hazard ratio was 0.46 (95% confidence interval: 0.25-0.84; p = 0.01) across three studies. All included studies had a high quality based on the Newcastle-Ottawa Scale. Certainty of evidence for OS was low. Certainty of evidence for CSS was moderate due to a strong association (hazard ratio <0.5). Publication bias was not significant for any studies. CONCLUSION: In UTUC patients with VH, administration of AC after surgery might have better survival outcomes than surgery alone. Our study provides evidence for decision-making of clinicians who treat UTUC patients with VH.

BACKGROUND: Recent studies have shown that donor nephrectomy can induce renal function impairment. However, few meta-analysis studies about this have proceeded. Therefore, the objective of this systematic review and meta-analysis including all data of recent research studies was to determine whether living donor nephrectomy (LDN) could induce renal function impairment. METHODS: By November 2020, comprehensive literature searches were performed on PubMed, Embase, and Cochrane databases. Inclusion criteria were: (1) observational studies with data about overall end-stage renal disease (ESRD) or chronic kidney disease (CKD) of living kidney donors, (2) control group consisted of people without donor nephrectomy, and (3) outcomes of studies included long-term end-stage renal disease risks after living kidney donation. Risk of Bias in Non-randomized Studies of interventions (ROBINS-I) assessment tool was used to evaluate our methodological quality. RESULTS: The qualitative review included 11 studies and the meta-analysis included 5 studies. In the meta-analysis, the integrated overall ESRD risk was 5.57 (95% CI: 2.03-15.30). Regarding the overall risk of bias using ROBINS-I assessment tool, 0 studies was rated as "Low", 7 studies were rated as "moderate", 2 studies were rated as "Serious", and two studies were rated as "Critical". CONCLUSIONS: Our study showed that LDN increased ESRD risk in LDN patients. However, in our meta-analysis, variables in included studies were not uniform and the number of included studies was small. To have a definite conclusion, meta-analyses of well-planned and detailed studies need to be conducted in the future.

BACKGROUND: Several cohort studies have explored the relationship between androgen deprivation therapy (ADT) and the severity of coronavirus disease 2019 (COVID-19). This study aimed to characterize the relationship between ADT and the severity of COVID-19 in patients with prostate cancer. METHODS: A systematic search was conducted using PubMed, Embase, and Cochrane Library databases from the inception of each database until February 31, 2020. Patients with prostate cancer who were treated with ADT were assigned to treatment group while those patients who were not treated with ADT were assigned to the control group. Outcomes were severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) positivity, hospitalization, intensive care unit (ICU) admission, and death. The risk of bias was evaluated using ROBINS-I (Risk Of Bias In Non-randomized Studies of Interventions) tool. RESULTS: Three studies with qualitative synthesis were included. Finally, two studies with quantitative synthesis having a total of 44,213 patients were included for the present systematic review. There was no significant difference in SARS-CoV-2 positive rate (odds ratio [OR], 0.52; 95% confidence intervals [Cis], 0.13-2.09; P = 0.362), hospitalization (OR, 0.52; 95% CIs, 0.07-3.69; P = 0.514), ICU admission (OR, 0.93; 95% CIs, 0.39-2.23, P = 0.881), or death (OR, 0.88; 95% CIs, 0.06-12.06; P = 0.934) between ADT and non-ADT groups. CONCLUSION: Qualitative and quantitative analyses of previous studies revealed no significant effect of ADT on COVID-19. However, more studies with higher quality that explore biochemical and immunological factors involved are needed to confirm this finding in the future.

OBJECTIVES: To investigate the association between lower urinary tract symptoms (LUTS) and cardiovascular disease (CVD) risk in women, as severe LUTS are known to be associated with CVD risk in men but few studies have focused on this issue in women. SUBJECTS AND METHODS: A total of 1014 ostensibly healthy women, who participated in a voluntary health check in a health promotion centre from November 2013 to October 2015, were enrolled. LUTS were assessed using the International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS). CVD risk scores were calculated using the Framingham risk score and the American College of Cardiology/American Heart Association Atherosclerotic Cardiovascular Disease (ASCVD) score. Correlation, partial correlation, and multiple logistic regression analyses were conducted. RESULTS: The mean age and body mass index (BMI) of the women were 51 years and 22.6 kg/m2 , respectively. The ASCVD score showed significant positive correlations with IPSS items Question 2 (Q2), Q3, Q5, and Q7 (all P < 0.05), total IPSS (P = 0.001), IPSS storage (P = 0.006) and IPSS voiding symptoms scores (P = 0.001) based on partial correlation analysis after adjustment for BMI. For the OABSS, the ASCVD score showed significant positive correlations with OABSS items Q2, Q3, and Q4 (P < 0.001, P = 0.017, and P < 0.001, respectively) and total OABSS (P < 0.001). Multiple logistic regression analysis showed that the moderate-severe risk groups of the OABSS and IPSS were associated with the ASCVD risk score in adjusted models (P < 0.001) compared to the none-mild OABSS and mild IPSS groups. After adjustment for age and BMI, IPSS storage score was significantly related with the ASCVD risk score (B = 0.855, P = 0.016) CONCLUSIONS: LUTS, especially storage symptoms, might be risk factors for predicting future CVD risk in women. Further prospective or cohort studies are needed to validate this possibility.

BACKGROUND: The aim of this study was to investigate the diagnostic accuracy of contrast-enhanced computed tomography (CT) and contrast-enhanced magnetic resonance imaging (MRI) of small renal masses in real practice. METHODS: Contrast-enhanced CT and MRI were performed between February 2008 and February 2013 on 68 patients who had suspected small (≤4 cm) renal cell carcinoma (RCC) based on ultrasonographic measurements. CT and MRI radiographs were reviewed, and the findings of small renal masses were re-categorized into five dichotomized scales by the same two radiologists who had interpreted the original images. Receiver operating characteristics curve analysis was performed, and sensitivity and specificity were determined. RESULTS: Among the 68 patients, 60 (88.2 %) had RCC and eight had benign disease. The diagnostic accuracy rates of contrast-enhanced CT and MRI were 79.41 and 88.23 %, respectively. Diagnostic accuracy was greater when using contrast-enhanced MRI because too many masses (67.6 %) were characterized as "4 (probably solid cancer) or 5 (definitely solid cancer)." The sensitivity of contrast-enhanced CT and MRI for predicting RCC were 79.7 and 88.1 %, respectively. The specificities of contrast-enhanced CT and MRI for predicting RCC were 44.4 and 33.3 %, respectively. Fourteen diagnoses (20.5 %) were missed or inconsistent compared with the final pathological diagnoses. One appropriate nephroureterectomy and five unnecessary percutaneous biopsies were performed for RCC. Seven unnecessary partial nephrectomies were performed for benign disease. CONCLUSIONS: Although contrast-enhanced CT and MRI showed high sensitivity for detecting small renal masses, specificity remained low.

BACKGROUND: Although there is growing evidence of relationship between obesity and some specific stone compositions, results were inconsistent. Due to a greater relationship between metabolic syndrome and some specific stone type, obesity measured by body mass index (BMI) has limitation in determining relationship between obesity and stone compositions. The aim of this study was to determine the relationship among BMI, visceral fat, and stone compositions. METHODS: We retrospectively reviewed data of patients with urinary stone removed over a 5 year period (2011-2014). Data on patient age, gender, BMI, urinary pH, stone composition, fat volumes (including visceral fat, subcutaneous fat, total fat, waist circumference), and ratio for visceral to total fat using computed tomography based delineation were collected. To figure out the predicting factor while adjusting other confounding factors, discriminant analysis was used. RESULTS: Among 262 cases, average age was 52.21 years. Average BMI and visceral fat were 25.03 cm(2) and 124.75 cm(2), respectively. By chi square test, there was significant (p < 0.001) difference in stone types according to sex. By ANOVA test, BMI, visceral fat, visceral to subcutaneous fat ratio, the percentage of visceral fat and total fat showed significant association with stone types. By discriminant analysis, visceral fat was proved to be a powerful factor to predict stone composition (structure matrix of visceral fat = -0.735) with 42.0% of predictive value. CONCLUSION: Visceral fat adiposity strongly related with uric acid stone and has better predictive value than BMI or urinary pH to classify the types of stone.

BACKGROUND: The efficacy of medical treatment among obese men with lower urinary tract symptoms (LUTS) has been less clear, especially regarding the improvement of QoL. We aimed to investigate the difference in efficacy and consequent satisfaction of life quality after medical treatment of male LUTS according to obesity. METHODS: An 8-week prospective study was performed for a total of 140 patients >50 years old with International Prostate Symptom Scores (IPSS) > 12 points and prostate volume > 20 mL. Obesity was determined by either body mass index (BMI) or waist circumference (WC). Patients were divided into 2 groups according to BMI or WC. Patients received tamsulosin at a dose of 0.4 mg daily for 8 weeks. The changes from baseline in the IPSS, maximal urinary flow rate (Qmax), post-void residual volume, questionnaire of quality of life (QoL), and King's Health Questionnaire (KHQ) were analyzed. RESULTS: Of the 150 enrolled patients, 96 completed the study. Seventy-five patients (78.1%) had BMI ≥ 23 kg/m2, and 24 (25.0%) had WC > 90 cm. Overall, the IPSS, IPSS QoL, and total KHQ showed significant improvement. Obese (BMI ≥ 23 kg/m2) and non-obese (BMI < 23 kg/m2) both showed improvement of the IPSS and IPSS QoL scores, but only the obese (BMI ≥ 23 kg/m2) group showed improvement of the total KHQ score (P < 0.001 vs. P = 0.55). Only the obese (WC > 90 cm) group showed improvement of the IPSS and total KHQ scores (P < 0.001). CONCLUSIONS: Our preliminary study showed the different efficacy of an alpha-blocker for improvement of LUTS and life quality according to obesity. Obese patients, defined by BMI or WC, showed the tendency toward a more favorable improvement of LUTS and life quality. TRIAL REGISTRATION: Current Controlled Trials 2010-058. Registered 2 September 2010 in Soonchunhyang University Hospital.

BACKGROUND: The core question of the study was whether adequately achieved HD affected the sexual dysfunction in women on hemodialysis (HD) with chronic renal failure (CRF). METHODS: Thirty-seven female patients on HD, including 18 women with adequate HD and 19 women with non-adequate HD, and 36 healthy controls were included in this study. Demographic and clinical variables, including the sexual hormones estradiol and testosterone, were recorded. Sexual function was assessed according to the Female Sexual Function Index (FSFI) and results were compared between groups. Adequate HD was defined as an average urea clearance of over 1.3 (Kt/V) over three consecutive months. RESULTS: All domains of the FSFI questionnaire, with the exception of satisfaction, were higher in the control group than in the HD group. In comparing the adequate and non-adequate HD groups, there was no difference in any of the six domains of the FSDI questionnaire. Among the clinical variables, the number of menopausal women was higher in the HD group than in the control group (P = 0.023). Estradiol and testosterone levels were higher in the control group than in the HD group (P = 0.003, 0.027, respectively). The number of menopausal women and estradiol and testosterone levels showed no differences between the adequate and non-adequate HD groups. Correlation analysis between Kt/V and FSFI showed no significant relationship, but estrogen did show a significant relationship with FSFI (correlation coefficient = 0.399, P = 0.001). CONCLUSIONS: HD adequacy alone does not have a significant impact on sexual dysfunction. Other treatments options should be considered to treat sexual dysfunction in women with CRF.

OBJECTIVES: To compare the treatment outcome of tamsulosin 0.4 mg (TAM) with or without solifenacin 5 mg (SOL) for the most bothersome symptom in male lower urinary tract symptoms (LUTS) with overactive bladder (OAB). SUBJECTS AND METHODS: Male LUTS/OAB (≥50 years) patients who had a total International Prostate Symptom Score (I-PSS) of ≥12, I-PSS urgency-related question of ≥2, and quality of life (QoL) of ≥3 points were enrolled. Patients who complained of storage symptoms as the most bothersome were included in the 'storage' group. Patients who complained of voiding symptoms as the most bothersome were included in the 'voiding' group. The change in the I-PSS was compared between the two groups 4 weeks after commencing treatment. RESULTS: In the storage group, 172 were able to finish this study (TAM: 88, TAM + SOL: 84). The improvement of I-PSS and QoL with TAM + SOL was significantly greater than with TAM alone (p < 0.001). In the voiding group, 108 were able to finish the study (TAM: 54, TAM + SOL: 54). The improvement of I-PSS and QoL with TAM alone was significantly greater than with TAM + SOL (p < 0.001). CONCLUSIONS: The most bothersome symptom in male LUTS/OAB should be considered when choosing the appropriate medical treatment.

BACKGROUND: Smartphone-based assessment may be a useful diagnostic and monitoring tool for patients. There have been many attempts to create a smartphone diagnostic tool for clinical use in various medical fields but few have demonstrated scientific validity. OBJECTIVE: The purpose of this study was to develop a smartphone application of the International Prostate Symptom Score (IPSS) and to demonstrate its validity and reliability. METHODS: From June 2012 to May 2013, a total of 1581 male participants (≥40 years old), with or without lower urinary tract symptoms (LUTS), visited our urology clinic via the health improvement center at Soonchunhyang University Hospital (Republic of Korea) and were enrolled in this study. A randomized repeated measures crossover design was employed using a smartphone application of the IPSS and the conventional paper form of the IPSS. Paired t test under a hypothesis of non-inferior trial was conducted. For the reliability test, the intraclass correlation coefficient (ICC) was measured. RESULTS: The total score of the IPSS (P=.289) and each item of the IPSS (P=.157-1.000) showed no differences between the paper version and the smartphone version of the IPSS. The mild, moderate, and severe LUTS groups showed no differences between the two versions of the IPSS. A significant correlation was noted in the total group (ICC=.935, P<.001). The mild, moderate, and severe LUTS groups also showed significant correlations (ICC=.616, .549, and .548 respectively, all P<.001).There was selection bias in this study, as only participants who had smartphones could participate. CONCLUSIONS: The validity and reliability of the smartphone application version were comparable to the conventional paper version of the IPSS. The smartphone application of the IPSS could be an effective method for measuring lower urinary tract symptoms.

OBJECTIVES: To evaluate the impact of obesity on the biopsy detection of prostate cancer. METHODS: We retrospectively reviewed data of 1182 consecutive Korean patients (≥50 years) with serum prostate-specific antigen levels of 3-10 ng/mL who underwent initial extended 12-cores biopsy from September 2009 to March 2013. Patients who took medications that were likely to influence the prostate-specific antigen level were excluded. Receiver operating characteristic curves were plotted for prostate-specific antigen and prostate-specific antigen density predicting cancer status among non-obese and obese men. RESULTS: A total of 1062 patients (mean age 67.1 years) were enrolled in the analysis. A total of 230 men (21.7%) had a positive biopsy. In the overall study sample, the area under the receiver operator characteristic curve of serum prostate-specific antigen for predicting prostate cancer on biopsy were 0.584 and 0.633 for non-obese and obese men, respectively (P = 0.234). However, the area under the curve for prostate-specific antigen density in predicting cancer status showed a significant difference (non-obese 0.696, obese 0.784; P = 0.017). CONCLUSIONS: There seems to be a significant difference in the ability of prostate-specific antigen density to predict biopsy results between non-obese and obese men. Obesity positively influenced the overall ability of prostate-specific antigen density to predict prostate cancer.

PURPOSE: To evaluate how a family history of prostate cancer influences the progression of the disease in individuals with prostate cancer undergoing active surveillance. MATERIALS AND METHODS: We conducted a thorough literature search in PubMed/MEDLINE, Embase, and Cochrane Library up to June 2023. This systematic review was registered in PROSPERO (CRD42023441853). The study evaluated the effects of family history of prostate cancer (intervention) on disease progression (outcome) in prostate cancer patients undergoing active surveillance (population) and compared them to those without a family history (comparators). For time to disease progression outcomes, the extracted data were synthesized using the inverse variance method on the log hazard ratios scale. RESULTS: A total of eight studies were incorporated into this systematic review and meta-analysis. The combined hazard ratio for unadjusted disease progression was 1.06 (95% confidential interval [CI] 0.66-1.69; p=0.82). The combined hazard ratio for adjusted disease progression was 1.31 (95% CI 1.16-1.48; p<0.0001). All the enlisted studies demonstrated high quality based on the Newcastle-Ottawa scale. The certainty of evidence for univariate and multivariate analysis of disease progression was very low and low, respectively. Publication bias for all studies was not significant. CONCLUSIONS: For individuals with prostate cancer opting for active surveillance, a family history of prostate cancer may serve as an independent risk factor associated with an elevated risk of disease progression. Clinicians should be counseled about the increased risk of disease progression in patients with a family history of prostate cancer undergoing active surveillance.

PURPOSE: To conduct systematic review and meta-analysis to evaluate effects of neoadjuvant chemotherapy (NAC) on survival and histopathological outcomes of variant histology (VH) of urothelial carcinoma (UC) of bladder. METHODS: This systematic review was registered in PROSPERO (CRD42023389115). Literature search was conducted in PubMed/Medline, Embase, and Cochrane Library for studies published up to January 2023. Population, intervention, comparator, outcome, and study design were as follows: bladder cancer patients with VH (population), neoadjuvant chemotherapy (intervention), radical cystectomy only (comparators), oncological survival and pathologic response (outcomes), and retrospective or prospective (study design). RESULTS: Finally, a total of 17 studies were included in the present study (quantitative analysis, n = 17; qualitative analysis, n = 12). Pooled HR was 0.49 (95% CI: 0.31-0.76; P = .002) for OS. Pooled HR was 0.61 (95% CI: 0.38-0.98; P = .04) for CSS. Pooled HR was 0.44 (95% CI: 0.21-0.93; P = .03) in PFS. Pooled OR was 6.61 (95% CI: 4.50-9.73; P < .00001) in complete pathologic response. Pooled OR was 9.59 (95% CI: 3.56-25.85; P < .00001) in any pathologic response. Evidence quality assessments for each 5 comparisons using the GRADE approach were that Certainty was moderate in 1, low in 1, and very low in 3. CONCLUSIONS: Administration of NAC before surgery in bladder cancer patients with VH might confer better survival outcomes and higher pathologic down staging rate than no administration of NAC before surgery.

PURPOSE: Cardiovascular disease (CVD) is one of the leading causes of death, accounting for one-third of all deaths worldwide. Patients with CVD are three times more likely to complain of sexual dysfunction than healthy people. Causes of sexual dysfunction in patients with CVD include physical/mental changes and drug side effects. The prevalence of sexual dysfunction in patients with CVD has been estimated to be up to 89%. Ordinary treatments such as pharmacotherapy cannot effectively reduce sexual problems. Therefore, sexual rehabilitation has a broad spectrum, including exercise therapy such as pelvic floor muscle treatment, appropriate counseling, a multidisciplinary approach, and partner rehabilitation. In this study, systematic review and meta-analysis was performed to investigate the effect of sexual rehabilitation on sexual problems in patients with CVD. MATERIALS AND METHODS: Comprehensive literature searches were conducted using MEDLINE, Cochrane Library electronic database, and EMBASE through June 2022. Questionnaire scores at the end point as outcomes of the study were recorded as were standardized mean difference (SMD) with their 95% confidence intervals (CIs). Meta-regression analysis was conducted for each moderator. We performed a risk of bias evaluation for included studies using the RoB 2 tool. RESULTS: The overall SMD in the meta-analysis for sexual rehabilitation versus no-sexual rehabilitation was 0.430 (95% CI, 0.226-0.633). There was a statistical difference between groups. SMD changes were 0.674 (95% CI, 0.308-1.039) at one month and 0.320 (95% CI, 0.074-0.565) at six months. The regression analysis with all variables (number of patients, study duration, and questionnaire types) revealed no significance. CONCLUSIONS: This study indicates that sexual rehabilitation is an effective method with high therapeutic potential for sexual dysfunction of patients with CVD. However, for clinical application, well-designed studies with many patients should be conducted in the future and the standardization of rehabilitation protocols is required.
RESUMEN
Background: To compare the effects of different alpha-blocker regimes on acute urinary retention (AUR) and the success rate of trial without catheter (TWOC) among patients with AUR secondary to benign prostatic hyperplasia (BPH) to determine the most effective regime. Methods: A comprehensive literature search was performed using PubMed/Medline, Embase, and Cochrane Library up to June 2021. Studies that compared successful TWOC rates between each alpha-blocker regime in patients with AUR secondary to BPH were included. The outcome was the odds ratio of successful TWOC after AUR between groups (each regime of alpha blocker or placebo). To indirectly compare the effect of each alpha-blocker regime on the outcome (successful TWOC rate), a network meta-analysis was conducted using a Bayesian hierarchical random effects model for dichotomous outcomes. Results: In total, 13 randomized controlled trials were included in the present study. There were six nodes (five alpha-blocker regimes and placebo) and eight comparisons in the evidence network plot. Compared to placebo, alfuzosin, silodosin, tamsulosin, and alfuzosin plus tamsulosin resulted in significantly higher TWOC success rates, whereas doxazosin did not show a significant difference in TWOC success rate compared to placebo. Alfuzosin plus tamsulosin was ranked first, followed in order by tamsulosin, silodosin, alfuzosin, and doxazosin. There was no significant inconsistency in the results of this analysis. Conclusions: Alpha blockers may increase the success rate of TWOC. This study evaluated the priority of the effect of several alpha-blocker regimens on AUR related to BPH, which is expected to be helpful in selecting the best medication for patients with AUR.
RESUMEN
UNLABELLED: Study Type--Prevalence (prospective cohort) Level of Evidence 1b. What's known on the subject? and What does the study add? Managing foreign bodies, including mesh and stones, after anti-incontinence surgery is important because complete removal is necessary to prevent infection and recurrence of stone formation. Traditionally, surgical management of such complications has involved excision using a transurethral approach, with or without a laparoscopic transvesical procedure. The study shows that mesh complications, including exposure and adherent stones, can be successfully treated and a fast recovery can be achieved using transvesical laparoscopic excision and reconstruction. Transvesical laparoscopy is especially suitable for cases that have a restricted visual field with cystoscopy; the technique allows complete removal of mesh/stones and reconstruction with the help of an excellent visual field. OBJECTIVES: ⢠To evaluate laparoscopic transvesical excision and reconstruction for the management of vesical mesh or stones around the bladder neck as complications of anti-incontinence intervention. ⢠To compare the techniques, outcomes and recurrence rates of laparoscopic transvesical excision and reconstruction with published results from studies using laparoscopic transvesical procedures. PATIENTS AND METHODS: ⢠We conducted a retrospective review of three patients who underwent laparoscopic transvesical excision and reconstruction for vesical mesh and stones around the bladder neck. ⢠Patients were identified from operating records including recorded video and electronic data records. ⢠We also conducted a literature review of the available evidence on transvesical laparoscopy for lower urinary tract complications of anti-incontinence procedures. RESULTS: ⢠Between March 2005 and May 2011, three women underwent laparoscopic transvesical excision and reconstruction. All presented with storage symptoms and gross haematuria. The interval between surgery and the diagnosis of presence of a foreign body was 1-3 years. ⢠Two women had previously undergone transobturator tape procedures and one had undergone a retropubic procedure. ⢠Complete excision including the mucosa and muscle layer and reconstruction with intravesical sutures was achieved in all cases. ⢠Storage symptoms were resolved within 3 days and haematuria was not observed. ⢠None of the women had recurrent erosion at follow-up. CONCLUSIONS: ⢠Laparoscopic transvesical excision and reconstruction is a technically feasible method. ⢠This procedure offers excellent visualization of mesh materials and stones, especially in cases of location near the anterior bladder neck. ⢠In selected patients, laparoscopic transvesical excision and reconstruction is an acceptable technique for first-line treatment of complications of anti-incontinence procedures.

BACKGROUND: Because of limited differentiation to endothelium from mesenchymal stem cells, it has been strongly recommended to use endothelial progenitor cells for the regeneration of the damaged endothelium of corpora cavernosa. This study was performed to investigate the immortalized human cerebral endothelial cells and their capability for repairing erectile dysfunction in a rat model of cavernous nerve injury. Circulating endothelial progenitor cells were isolated from human fetal brain vasculature at the periventricular region of telencephalic tissues. Over 95% of CD 31-positive cells were sorted and cultured for 10 days. Human cerebral endothelial progenitor cells were injected into the cavernosa of rats with cavernous nerve injury. Erectile response was then assessed. In in vivo assays, rats were divided into three groups: group 1, sham operation: group 2, bilateral cavernous nerve injury: and group 3, treatment with human cerebral endothelial cells after cavernous nerve injury. RESULTS: Established immortalized circulating endothelial progenitor cells showed expression of human telomerase reverse transcriptase transcript by RT-PCR. They also showed the expression of vascular endothelial growth factor, von Willebrand factor, vascular endothelial growth factor receptor, and CD31, cell type-specific markers for endothelial cells by RT-PCR. In in vitro angiogenesis assays, they demonstrated tube formation that suggested morphological properties of endothelial progenitor cells. In in vivo assays, impaired erectile function of rat with cavernous nerve injury recovered at 2, 4, and 12 weeks after transplantation of human cerebral endothelial cells into the cavernosa. CONCLUSIONS: Telomerase reverse transcriptase-circulating endothelial progenitor cells from fetal brain vasculature could repair erectile dysfunction of rats with cavernous nerve injury.
RéSUMé: CONTEXTE: En raison de la différenciation limitée de l'endothélium à partir de cellules souches mésenchymateuses, il a été fortement recommandé d'utiliser des cellules progénitrices endothéliales pour la régénération de l'endothélium endommagé des corps caverneux. Cette étude a été réalisée pour étudier les cellules endothéliales cérébrales humaines immortalisées, et leur capacité à réparer la dysfonction érectile dans un modèle de rat avec lésion du nerf caverneux. Les cellules progénitrices endothéliales circulantes ont été isolées du système vasculaire cérébral fÅtal humain dans la région périventriculaire des tissus télencéphaliques. Plus de 95% des cellules CD31 positives ont été sélectionnées et cultivées pendant 10 jours. Des cellules progénitrices endothéliales cérébrales humaines ont été injectées dans les corps caverneux de rats présentant une lésion nerveuse des corps caverneux. La réponse érectile a ensuite été évaluée. Dans les essais in vivo, les rats ont été divisés en trois groupes: groupe 1, opération simulée; groupe 2, lésion bilatérale du nerf caverneux; et groupe 3, traitement par cellules endothéliales cérébrales humaines après lésion du nerf caverneux. RéSULTATS: Les cellules progénitrices endothéliales circulantes immortalisées établies ont montré l'expression de la transcription de la transcriptase inverse de la télomérase humaine par RT-PCR. Elles ont également montré l'expression du facteur de croissance de l'endothélium vasculaire, du facteur de von Willebrand, du récepteur du facteur de croissance de l'endothélium vasculaire, et de CD31, marqueurs spécifiques du type cellulaire par RT-PCR pour les cellules endothéliales. Dans les essais in vivo, la fonction érectile altérée des rats avec lésion du nerf caverneux s'est rétablie à 2, 4 et 12 semaines après transplantation de cellules endothéliales cérébrales humaines dans les corps caverneux. CONCLUSIONS: Les cellules progénitrices endothéliales circulantes exprimant la transcriptase inverse de la télomérase, provenant du système vasculaire cérébral fÅtal humain, pourraient réparer la dysfonction érectile de rats atteints de lésions des nerfs caverneux. MOTS-CLéS: Dysfonction érectile; Cellules endothéliales humaines; Transcriptase inverse de la Télomérase humaine.
RESUMEN
PURPOSE: This study aimed to evaluate benign prostatic hyperplasia (BPH) diagnosis rate and the changing landscape of medical and surgical management of BPH over the last decade using national population data of South Korea. METHODS: The present study analyzed data of patients diagnosed with BPH (N40) who underwent medical treatment or surgery in 3% of the national patient sample of the Health Insurance and Review Assessment database each year between 2012 and 2018. The primary outcome was the proportion of medical and surgical treatment for BPH. It was evaluated each year between 2012 and 2018. Secondary outcomes included total BPH diagnosis rate in each year of the study period. BPH diagnosis rate by age group was evaluated. The proportion of medical and surgical treatment for BPH according to the type of medical institution was investigated. RESULTS: The proportion of surgical treatment was 1.2% in 2012, 1.0% in 2013, 1.0% in 2014, 0.9% in 2015, 0.8% in 2016, 0.7% 2018, and 0.8% 2018, showing a progressive overall decrease from 2012 to 2018. The rate of surgical treatment for BPH increased with increasing age during the study period, showing a progressive overall increase (from 9,202 per 100,000 men in 2012 to 11,610 per 100 000 men in 2018). The number of patients with BPH was increased steadily from 2012 to 2018 in all age groups. The rate of surgical treatment in tertiary referral hospitals was the highest during the study period, followed by that in general hospitals, hospitals, and clinics. CONCLUSIONS: In Korea, the diagnosis rate of BPH was steadily increasing during the study period. Overall surgical treatment gradually decreased compared with an increase in medical treatment among all treatments for BPH. Thus, a comprehensive treatment plan for BPH should be established considering this trend.
RESUMEN
INTRODUCTION: Although several studies have been conducted to evaluate the feasibility of Raman spectroscopy (RS) for the diagnosis of bladder cancer (BCa), it is difficult to use RS in real clinical settings based on the current limited evidence. Therefore, we performed a systematic review and meta-analysis to assess the diagnostic accuracy of RS in BCa. MATERIALS AND METHODS: Comprehensive literature searches were performed in the PubMed/Medline, Embase, and Cochrane Library databases up to March 2019. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, this study included reports according to the participant, intervention, comparator, outcomes, and study design approach. The methodological quality of the included studies was evaluated according to questionnaires and criteria suggested by the Quality Assessment of Diagnostic Accuracy Studies-2 tool. The quantitative outcomes included diagnostic accuracy (sensitivity and specificity). RESULTS: Fifteen studies were included for qualitative analysis and four studies (BCa cases, n = 139; control cases n = 107) were included in this analysis by screening the full text of the remaining articles based on the inclusion and exclusion criteria through a systematic review. The pooled sensitivity and specificity of RS were 0.91 (95% confidence interval [CI]: 0.85-0.95) and 0.93 (95% CI: 0.86-0.97), respectively. The among-study heterogeneity was statistically significant in the specificity results (Cochran Q statistic, P = 0.015; I2 statistic, 71.3%) but not in the sensitivity results (Cochran Q statistic, P = 0.189; I2 statistic, 37.2%). CONCLUSIONS: RS showed the potential to be an efficient tool with high accuracy for detecting malignant bladder lesions. More studies with in vivo real-time settings are warranted to validate our results.

PURPOSE: We investigated whether ADT use was associated with the risk of ischemic cardiovascular diseases (CVD) and cerebrovascular diseases (CrVD) in a nationwide population-based cohort. METHODS: Claims data of the Health Insurance and Review Assessment system in South Korea were used. In total, 195,308 men with newly diagnosed prostate cancer between January 1, 2008 and December 31, 2017 were identified. After applying the exclusion criteria, 131,189 men were enrolled. The study cohort was divided into ADT and non-ADT groups. Study outcomes were newly developed CVD, cardiovascular intervention (CVI), and CrVD. To control for potential confounders, various cardiovascular risk factors were balanced between groups. Cox proportional hazard regression models were used to estimate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of events. RESULTS: Univariable analysis revealed that ADT was significantly associated with an increased risk of CVD and CrVD. Multivariable analysis did not reveal this association. In the propensity score matched cohort (n = 61,722), multivariable analysis demonstrated that ADT independently reduced the risk of CVD (HR 0.890; 95% CI 0.846-0.936; p < 0.0001), CVI (HR 0.873; 95% CI 0.770-0.991; p = 0.0352), and CrVD (HR 0.869; 95% CI 0.824-0.917; p < 0.0001). CVD risk was significantly decreased in patients using ADT for over 2 years. CVI and CrVD risks were significantly lower in men using ADT for over 3 years. CONCLUSION: This study demonstrated that ADT may reduce the risk of CVD, CVI, and CrVD, and ADT duration is associated with this risk reduction.
