Challenging the Urologist of the Future: Time for a Change?

Physicians need both medical expertise and diverse skills for effective patient care. Adaptability is also key in embracing advances in technology and new techniques. We outline six thought-provoking points to guide the new generation of urologists.

Anti-sperm Antibody Positivity in Men with Varicocele: A Systematic Review and Meta-Analysis.

PURPOSE: Despite the significant role of varicocele in the pathogenesis of male infertility, its association with anti-sperm antibodies (ASA) remains controversial. This systematic review and meta-analysis (SRMA) aims to investigate the frequency of ASA positivity in men with varicocele. MATERIALS AND METHODS: This SRMA is conducted in accordance with the Meta-analysis of Observational Studies in Epidemiology guidelines. We investigated the frequency of ASA positivity in ejaculates or serum of men with varicocele as compared to men without varicocele (controls). A literature search was performed using the Scopus and PubMed databases following the Population Exposure Comparison Outcome, Study Design model. Data extracted from eligible studies were meta-analyzed and expressed as odds ratios (ORs) and confidence intervals (CIs). RESULTS: Out of 151 abstracts identified during the initial screening, 6 articles met the inclusion criteria and were included in the meta-analysis. Using mixed antiglobulin reaction (MAR) assay, 61 out of the 153 (39.8%) patients with varicocele tested positive for ASA in their ejaculates as compared to 22 out of the 129 control subjects (17%, OR=4.34 [95% CI: 1.09-17.28]; p=0.04). Using direct or indirect immunobead test, 30 out of 60 cases diagnosed with varicocele (50%) had shown ASA positivity in their ejaculates as compared to 16 out of 104 controls (15.4%, OR=3.57 [95% CI: 0.81-15.68]; p=0.09). Using enzyme-linked immunosorbent assay (ELISA), out of 89 varicocele patients, 33 (37.1%) tested positive for serum ASA as compared to 9 out of 57 participants in the control group (15.8%, OR=7.87 [95% CI: 2.39-25.89]; p<0.01). CONCLUSIONS: This SRMA indicates that ASA positivity is significantly higher among men with varicocele when tested by direct method (MAR) or indirect method (ELISA). This data suggests an immunological pathology in infertile men with varicocele and may have implications for the management of these patients.

Surgical treatment of premature ejaculation: a narrative review.

Recurrence after drug cessation is the biggest drawback of medical premature ejaculation (PE) treatments. Although these treatments are demonstrated to be safe and effective, most of the PE patients are interested in a more permanent solution. Despite the fact that currently available guidelines do not recommend surgical treatment for PE, some surgical interventions have been commonly performed for many years, especially in the Asian countries. The main purpose of these surgical treatments is to decrease the sensitivity of the glans penis. However, they are associated with irreversible complications such as penile deformity, sensory loss and erectile dysfunction. The aim of this narrative review is to summarize the advantages and disadvantages of various surgical interventions introduced for the treatment of PE. PubMed, Scopus and Web of Science have been utilized to search articles about glans penis augmentation and penile dorsal nerve interventions. A total of 11 articles were included, three articles excluded because they were in non-English languages. Glans penis augmentation offered a less invasive treatment that avoids severe side effects but requires retreatment in time. Selective dorsal neurectomy provided a more invasive but curative treatment alternative. However, more clinical data are necessary before surgical treatment options can be recommended to patients with PE.

Antibiotics in the Treatment of Uncomplicated Cystitis: A Google Trends Analysis.

INTRODUCTION: Using Google Trends (GT) data, the trend variations for the most common antibiotics used to treat uncomplicated cystitis were analyzed by time and region since 2004. METHODS: GT was used to create a "line-graph" that shows how interest in a topic in certain locations has grown or decreased over time. The relative search volume, which is displayed on a scale of 0-100, was used to index the search values for specific phrases. Nitrofurantoin (NFN), fosfomycin (FOS), trimethoprim (TMP), pivmecillinam (PIV), and cefadroxil are among the antibiotics recommended by the European Association of Urology (EAU) and the American Urological Association for the treatment of uncomplicated cystitis. Using the "global" inquiry category, the data was searched "worldwide" from 1 February 2004 to 31 December 2021. RESULTS: In the regression analysis, all antibiotics exhibited positive trends (p < 0.05). With a steady rise in popularity, NFN is the most popular antibiotic today. Search trend for cefadroxil stayed nearly stable until 2012, the rate of rise in the last 10 years increased, and cefadroxil is the second most popular antibiotic. In the previous 5 years, there was a decline in interest in TMP. In recent years, there was an increase in the trends for FOS and PIV. CONCLUSION: Clinicians and patients all around the world increasingly use the web to search for antibiotic therapies for uncomplicated cystitis. Antibiotics used to treat uncomplicated cystitis have various trends in different continents throughout the world. The web trends seem to be compatible with daily use.

Global Web Trends Analysis of Minimally Invasive Urinary Stone Treatment in the Last Decade and During the COVID-19 Pandemic.

With the rising incidence of urinary stone disease, web searches for stone treatments are increasing. Google Trends (GT) data for a 10-year period and during the coronavirus disease 2019 (COVID-19) pandemic were used to investigate the trend variations for the most popular minimally invasive stone therapies based on time and region. GT can create a line graph that shows how interest in various territories has risen or decreased over time. Search terms were generated for extracorporeal shockwave lithotripsy (SWL), percutaneous nephrolithotomy (PCNL), retrograde intrarenal surgery (RIRS), ureterorenoscopy (URS), and laparoscopic pyelolithotomy/ureterolithotomy. Using the "global" inquiry category, the data were included "worldwide" from January 1, 2009 to December 31, 2021. In recent years, Google and YouTube searches for total minimally invasive stone treatments have increased. RIRS, URS, and PCNL trends revealed a substantial rise in the regression analysis (p < 0.05), but SWL trends showed a significant reduction (p < 0.05). RIRS was the main intervention with interest growing most over time. Web searches for stone treatments decreased in the first period of the COVID-19 pandemic. To a rising degree of involvement, patients and physicians from all over the world utilize the internet to search for minimally invasive stone operations. RIRS, URS, and PCNL are becoming more popular in web trends and SWL still has the highest trend despite the decline in popularity recently. The number of trustworthy web-based tools about stone treatments should be increased, and patients and physicians should be directed to these sources.

Erectile dysfunction treatment with Phosphodiesterase-5 Inhibitors: Google trends analysis of last 10 years and COVID-19 pandemic.

OBJECTIVES: We aimed to analyze the trend change of the most popular Phosphodiesterase-5 Inhibitors (PDE5i) over time and geography by using Google Trends (GT) data in 10 years period and COVID-19 pandemic. MATERIALS AND METHODS: GT is able to generate a "line-graph", showing how interest has increased or decreased over a period within specific territories. The search values for specific terms are indexed as relative search volume (RSV), which is presented on a scale from 0-100. Avarage annual percentage change (AAPC) and RSV were analyzed to evaluate gain or loss of interest in trends. Search terms were generated for Food and Drug Administration (FDA)-approved PDE5i; tadalafil, sildenafil, vardenafil, avanafil, and their most-used brand names. The data was within "worldwide" from 1 January 2010, to 31 December 2020, using the ''global'' query category. RESULTS: The overall interest in PDE5i has doubled. Sildenafil has become the most trend PDE5i of today with a regular increase (AAPC: 0.016, p < 0.01). Although the search trend of tadalafil remained almost constant until 2014, the rate of increase in the last 6 years raised and tadalafil has become the 2nd most popular PDE5i recently (AAPC: 0.007, p < 0.01). For vardenafil there has been a decreased interest (AAPC: -0.009, p < 0.01). There is no significant change in avanafil trend (AAPC: 0.000, p: 0.5). All PDE5i interest on GT decreased notably from February to June 2020. But after June, search trends reached the level before the COVID-19 period in a month. CONCLUSIONS: These findings show us, with its increasing prevalence, erectile dysfunction (ED) has become a major public health problem. People from different geographies search the internet for ED treatment options. Patients should be informed that ED may be the first sign of many comorbid diseases, and patients with ED should be referred to a health institution for diagnosis and treatment.

Urinary microbiota; Which non-invasive urine collection method should we use?

OBJECTIVE: The aim of this study is to establish the optimal non-invasive urine sample collection method for the microbiota studies. METHODOLOGY: Twelve men with bladder carcinoma underwent first voided and midstream urine collection. Urine samples were analysed using V3-V4 regions of bacterial 16s ribosomal RNAs. Bacterial groups with relative abundance above 1% were analysed in first voided urine and midstream urine samples at phylum, class, order and family level. At the genus level, all of the identified bacterial groups' relative abundances were analysed. The statistical significance (P < .05) of differences between first voided and midstream urine sample microbiota was evaluated using the Wilcoxon test. RESULTS: According to the analysis, 8 phyla, 14 class, 23 orders, 39 families and 29 different genera were identified in the first voided and the midstream urine samples. Statistical differences were not identified between first voided and midstream urine samples of all bacteria groups except the Clostridiales at order level (p:0.04) and Clostridia at class level (P: .04). CONCLUSIONS: Either first voided or midstream urine samples can be used in urinary microbiota studies as we determined that there is no statistically significant difference between them regarding the results of 16s ribosomal RNA analysis.

Prognostic value of preoperative inflammation markers in non-muscle invasive bladder cancer.

PURPOSE: To investigate the prediction values of the preoperative neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), platelet-lymphocyte ratio (PLR), mean platelet volume (MPV) and red cell distribution width (RDW) for recurrence and progression of patients with non-muscle invasive bladder cancer (NMIBC). METHODS: In this prospective study, 94 consecutive patients newly diagnosed with NMIBC between July 2017 and August 2018 were included. The blood samples were collected from patients before transurethral resection of bladder tumour (TURB) and NLR, LMR, PLR, RDW and MPV values were calculated. The effect of these preoperative inflammatory parameters and other clinicopathological parameters on recurrence and progression rates was evaluated. Kaplan-Meier and multivariate Cox regression analyses were performed to identify significant prognostic variables. RESULTS: The mean follow-up was 11 ± 6.4 months. Recurrence was observed in 35.1% and progression was detected in 7.4% of the patients. NLR was statistically significantly associated with both recurrence (P = .01) and progression (P = .035), whereas LMR was only associated with recurrence (P = .038). In the survival analyses, the relationship between recurrence and LMR was confirmed in both univariate (P = .021) and multivariate (P = .022) analyses. The relationship between NLR and recurrence was confirmed in univariate analysis (P = .019); however; in multivariate analysis, it was found to be statistically insignificant (P = .051). CONCLUSIONS: LMR might be an easy obtainable, non-invasive and cost-effective method for predicting recurrence of disease in patients with NMIBC.

Can we perform frozen section instead of repeat transurethral resection in bladder cancer?

OBJECTIVE: To confirm frozen section (FS) method for muscularis propria (MP) sampling and to compare the FS method with the ReTUR section (RS) procedure to reduce needing for second resection that can cause waste of time for definitive treatment of muscle-invasive bladder cancer. METHODS: A total of 27 patients who admitted to our clinic and was performed transurethral resection of bladder tumor (TUR-BT) due to bladder tumor and had an indication of ReTUR were evaluated prospectively in the study. During the first TUR-BT procedure (as permanent section), FS examination was also performed to the patients. ReTUR was performed 2-6 weeks after the first TUR-BT procedure. RESULTS: Presences of MP were observed in 51.8% and 77.7% of FS and permanent section examinations. In the comparing of the presence of residual tumor in the methods, although 12 of 27 patients were found to have a residual tumor in FS, it was found to be in only 6 of 12 patients in RS. There was no statistical significance between FS and RS methods for MP sampling and detecting of residual tumor. CONCLUSIONS: FS was found to be a comparable method with the RS method (ReTUR procedure) for the sampling of MP and detecting of residual tumor, despite the limitations in the pathological examination FS. Especially in patients with detected residual tumor after the pathological consultation of FS during the procedure, re-resection can be a choice at the end of the first TUR-BT instead of ReTUR.
