Tento článek zpracovává téma nových trendů a technologií v urologii, a to konkrétně v oblasti telemedicíny a umělé inteligence. Nejprve stručně pojednává o přínosech telemedicíny a jak mění pohled na vztah mezi lékařem a pacientem. Podrobněji se pak text věnuje především umělé inteligenci, jež se v současnosti dostává do popředí zájmu laické i odborné veřejnosti. Její potenciál v urologii je testován v mnoha studiích, především se zaměřením na uroonkologii, v menší míře pak také v oblasti benigních urologických onemocnění. Článek se snaží identifikovat nejvýznamnější pokroky v této rychle se rozvíjející oblasti, a zároveň předkládá současné limity jejího zapojení do klinické praxe.
This article explores the emerging trends and technologies in urology, focusing on telemedicine and artificial intelligence. It provides a brief overview of the benefits of telemedicine and its impact on the patient-physician interactions. The article subsequently explores in detail the use of artificial intelligence, which is currently gaining considerable interest from both general public and medical professionals. Its potential in urology has been tested in a number of clinical studies, particularly in the field of uro-oncology and, to a lesser extent, in benign urological diseases. The aim of this article is to identify the key advances in this rapidly evolving field, while also highlighting the current limitations of its implementation into clinical practice.

BACKGROUND AND OBJECTIVE: There is no standardized regimen for follow-up after radical cystectomy (RC) for bladder cancer (BC). To address this gap, we conducted a multicenter study involving urologist members from the European Association of Urology (EAU) bladder cancer guideline panels. Our objective was to identify consistent post-RC follow-up strategies and develop a practice-based framework based on expert opinion. METHODS: We surveyed 27 urologist members of the EAU guideline panels for non-muscle-invasive bladder cancer and muscle-invasive and metastatic bladder cancer using a pre-tested questionnaire with dichotomous responses. The survey inquired about follow-up strategies after RC and the use of risk-adapted strategies. Consistency was defined as >75% affirmative responses for follow-up practices commencing 3 mo after RC. Descriptive statistics were used for analysis. KEY FINDINGS AND LIMITATIONS: We received responses from 96% of the panel members, who provided data from 21 European hospitals. Risk-adapted follow-up is used in 53% of hospitals, with uniform criteria for high-risk (at least ≥pT3 or pN+) and low-risk ([y]pT0/a/1N0) cases. In the absence of agreement for risk-based follow up, a non-risk-adapted framework for follow-up was developed. Higher conformity was observed within the initial 3 yr, followed by a decline in subsequent follow-up. Follow-up was most frequent during the first year, including patient assessments, physical examinations, and laboratory tests. Computed tomography of the chest and abdomen/pelvis was the most common imaging modality, initially at least biannually, and then annually from years 2 to 5. There was a lack of consistency for continuing follow-up beyond 10 yr after RC. CONCLUSIONS AND CLINICAL IMPLICATIONS: This practice-based post-RC follow-up framework developed by EAU bladder cancer experts may serve as a valuable guide for urologists in the absence of prospective randomized studies. PATIENT SUMMARY: We asked urologists from the EAU bladder cancer guideline panels about their patient follow-up after surgical removal of the bladder for bladder cancer. We found that although urologists have varying approaches, there are also common follow-up practices across the panel. We created a practical follow-up framework that could be useful for urologists in their day-to-day practice.

BACKGROUND AND OBJECTIVE: We present a summary of the 2025 update for the European Association of Urology (EAU) guidelines for upper urinary tract urothelial carcinoma (UTUC). The aim is to provide practical recommendations on the clinical management of UTUC with a focus on diagnosis, treatment, and follow-up. METHODS: For the 2025 guidelines on UTUC, new and relevant evidence was identified, collated, and appraised via a structured assessment of the literature. Databases searched included Medline, EMBASE, and the Cochrane Libraries. Recommendations within the guidelines were developed by the panel to prioritise clinically important care decisions. The strength of each recommendation was determined according to a balance between desirable and undesirable consequences of alternative management strategies, the quality of the evidence (including the certainty of estimates), and the nature and variability of patient values and preferences. KEY FINDINGS AND LIMITATIONS: Key recommendations emphasise the importance of thorough diagnosis, treatment, and follow-up for patients with UTUC. The guidelines stress the importance of appropriate treatment taking into account patient values and preferences. Key updates in the 2025 UTUC guidelines include: significant changes to the recommendations for UTUC diagnosis; complete revision of the sections addressing risk stratification, ureteroscopy, and the surgical approach for radical nephroureterectomy; addition of four new recommendations, two related to kidney-sparing management of localised low-risk UTUC and a further two related to management of high-risk nonmetastatic UTUC; a review and adaptation of recommendation for UTUC follow-up; and addition of a new section addressing quality indicators for UTUC management. CONCLUSIONS AND CLINICAL IMPLICATIONS: This overview of the 2025 EAU guidelines on UTUC offers valuable insights into risk factors, diagnosis, classification, treatment, and follow-up for UTUC. The guidelines contain information on the management of individual patients according to the current best evidence and are designed for effective integration in clinical practice.

BACKGROUND AND OBJECTIVE: Bacillus Calmette-Guérin (BCG) reduces disease recurrence and progression in intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). BCG-associated adverse events during instillations are common, leading to treatment cessation. Prophylactic use of quinolones in conjunction with BCG instillations is one approach for reducing BCG-associated adverse events. Our aim was to delineate the clinical impact of quinolone prophylaxis (QP) in patients receiving adjuvant BCG instillations for NMIBC. METHODS: In October 2024, a systematic search of MEDLINE, Embase, and the Cochrane Central Register of controlled trials was performed. Prospective and retrospective studies reporting comparative outcomes for patients with and without QP during BCG instillations were included. Outcomes were reported in a binary fashion. Random-effects meta-analysis using the weighted mean difference was conducted. Primary outcomes for pooled analyses included BCG-associated toxicities, the completion rate for BCG induction, the likelihood of antituberculosis treatment, and disease recurrence and progression at 12 mo. KEY FINDINGS AND LIMITATIONS: The systematic review included five studies. Four randomised controlled trials were included in the meta-analysis, and one nonrandomised study was also included in the narrative review. The studies involved 445 patients, of whom 194 received QP + BCG and 251 received BCG alone. QP use was associated with lower incidence of class ≥2 (40.8% vs 54.7%; relative risk [RR] 0.79, 95% confidence interval [CI] 0.67-0.94; p = 0.006), and class ≥3 BCG-associated toxicities (25.3% vs 36.4%; RR 0.70, 95% CI 0.50-0.98; p = 0.04) and a higher completion rate for BCG induction (83.0% vs 70.6%; RR 1.16, 95% CI 1.01-1.34; p = 0.04). The 12-mo recurrence rates (14.7% vs 19.4%; RR 0.76, 95% CI 0.46-1.27; p = 0.3) and progression rates (4.5% vs 6.4%; RR 0.86, 95% CI 0.09-8.25; p = 0.9) did not significantly differ for QP + BCG versus BCG alone. CONCLUSIONS AND CLINICAL IMPLICATIONS: The use of QP with adjuvant BCG for NMIBC mitigated debilitating BCG-associated toxicities and improved the completion rate for BCG induction therapy.

BACKGROUND AND OBJECTIVE: Given the uncertainty regarding the role of radical nephroureterectomy (RNU) as part of a multimodal treatment strategy for upper tract urothelial carcinoma (UTUC) patients with cN+ disease, we aimed to perform a systematic review and meta-analysis of the corresponding literature. METHODS: Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, we identified 17 observational comparative and noncomparative studies, published between January 2000 and September 2024, evaluating UTUC patients with cTanyN+M0 disease (P) who received RNU as part of a multimodal treatment strategy (I), as compared with any treatment strategy if applicable (C), to assess oncological or postoperative outcomes (O). Meta-analyses were further performed, as appropriate. KEY FINDINGS AND LIMITATIONS: Overall, 15 studies evaluated the effectiveness of adding chemotherapy to RNU in the perioperative setting without specifying the exact timing of delivery (n = 1), in the induction setting (n = 14), or in the adjuvant setting (n = 5), while two studies evaluated the effectiveness of adding RNU to chemotherapy. Meta-analyses showed that the use of induction chemotherapy plus RNU versus RNU alone was associated with greater odds of pathological downstaging (risk ratio [RR] = 3.06; 95% confidence interval [CI] = [2.48-3.77]; p < 0.001; I2 = 0%; p = 0.44) and pathological complete nodal response (RR = 2.80; 95% CI = [2.03-3.86]; p < 0.001; I2 = 0%; p = 0.47) as well as prolonged overall survival (HR = 0.52; 95% CI = [0.42-0.64]; p < 0.001; I2 = 14%; p = 0.33) without any significant impact on the risk of overall (RR = 1.14; 95% CI = [0.79-1.64]; p = 0.48; I2 = 0%; p = 0.76) and major (RR = 0.48; 95% CI = [0.18-1.24]; p = 0.13; I2 = 0%; p = 0.87) postoperative complications. In addition, the use of induction chemotherapy plus RNU versus RNU plus adjuvant chemotherapy (HR = 0.58; 95% CI = [0.38-0.89]; p = 0.01) or chemotherapy alone (HR = 0.49; 95% CI = [0.32-0.76]; p = 0.001; I2 = 46%; p = 0.17) was associated with prolonged overall survival. Limitations include the observational design of all included studies. CONCLUSIONS AND CLINICAL IMPLICATIONS: The use of RNU could provide the greatest oncological benefits without any significant harm in selected UTUC patients with fit general condition and resectable cN+ disease responding to induction chemotherapy. PATIENT SUMMARY: In this report, we looked at the outcomes of radical surgery in combination with systemic chemotherapy for upper tract urothelial carcinoma with clinical evidence of dissemination to the surrounding lymph nodes. We observed that the use of radical surgery was associated with the greatest oncological benefits without any increased risk of postoperative complications in patients with fit general condition and resectable disease responding to induction chemotherapy. We conclude that the use of induction chemotherapy plus radical surgery could be the best multimodal treatment strategy for these patients.

PURPOSE: A re-transurethral resection of the bladder (re-TURB) is a well-established approach in managing non-muscle invasive bladder cancer (NMIBC) for various reasons: repeat-TURB is recommended for a macroscopically incomplete initial resection, restaging-TURB is required if the first resection was macroscopically complete but contained no detrusor muscle (DM) and second-TURB is advised for all completely resected T1-tumors with DM in the resection specimen. This study assessed the long-term outcomes after repeat-, second-, and restaging-TURB in T1-NMIBC patients. METHODS: Individual patient data with tumor characteristics of 1660 primary T1-patients (muscle-invasion at re-TURB omitted) diagnosed from 1990 to 2018 in 17 hospitals were analyzed. Time to recurrence, progression, death due to bladder cancer (BC), and all causes (OS) were visualized with cumulative incidence functions and analyzed by log-rank tests and multivariable Cox-regression models stratified by institution. RESULTS: Median follow-up was 45.3 (IQR 22.7-81.1) months. There were no differences in time to recurrence, progression, or OS between patients undergoing restaging (135 patients), second (644 patients), or repeat-TURB (84 patients), nor between patients who did or who did not undergo second or restaging-TURB. However, patients who underwent repeat-TURB had a shorter time to BC death compared to those who had second- or restaging-TURB (multivariable HR 3.58, P = 0.004). CONCLUSION: Prognosis did not significantly differ between patients who underwent restaging- or second-TURB. However, a worse prognosis in terms of death due to bladder cancer was found in patients who underwent repeat-TURB compared to second-TURB and restaging-TURB, highlighting the importance of separately evaluating different indications for re-TURB.

Na akutní urologickou ambulanci se dostavil 93letý pacient stěžující si na obtékající permanentní močový katétr a bolesti podbřišku. Mezi pro případ relevantní pacientovy diagnózy patřily velmi vysoce rizikový uroteliální karcinom močového měchýře po opakovaných transuretrálních resekcích a recentně také výplaších intravezikální chemoterapií, diabetes mellitus druhého typu na dvojkombinaci perorálních antidiabetik a recidivující močové infekce. Pro suspekci na perforaci močového měchýře či komunikaci močového měchýře se střevem, při sterkorálně zapáchající moči, bylo doplněno kontrastní CT s vylučovací fází a CT cystogram. Perforaci či píštěl jsme neprokázali, avšak na základě zobrazovacích vyšetření jsme stanovili diagnózu emfyzematózní cystitidy. Tato kazuistika má za cíl upozornit na tuto vzácnou, mnohdy nenápadně se projevující, avšak potenciálně život ohrožující urologickou nosologickou jednotku.
A 93-year-old male presented to the urology outpatient clinic with complaints of a leaking indwelling urinary catheter and suprapubic pain. Our patient had a history of urothelial carcinoma of the bladder, for which he has undergone multiple transurethral resections and recent intravesical chemotherapy instillations. He also has type 2 diabetes mellitus, which is managed with a combination of oral antidiabetic medications and has a history of recurrent urinary tract infections. A CT scan with contrast and an excretory phase and CT cystogram were performed to rule out bladder perforation or a bladder-bowel fistula in the presence of foul-smelling urine. The CT scan did not show any evidence of colo-vesicalor fistula, but it did show evidence of emphysematous cystitis. This case report aims to highlight this rare, often presenting in a subtle manner, but life-threatening urological disease.

BACKGROUND AND OBJECTIVE: This publication represents a summary of the updated 2024 European Association of Urology (EAU) guidelines for non-muscle-invasive bladder cancer (NMIBC), TaT1, and carcinoma in situ. The information presented herein is limited to urothelial carcinoma, unless specified otherwise. The aim is to provide practical recommendations on the clinical management of NMIBC with a focus on clinical presentation. METHODS: For the 2024 guidelines on NMIBC, new and relevant evidence was identified, collated, and appraised via a structured assessment of the literature. Databases searched included Medline, EMBASE, and the Cochrane Libraries. Recommendations within the guidelines were developed by the panel to prioritise clinically important care decisions. The strength of each recommendation was determined according to a balance between desirable and undesirable consequences of alternative management strategies, the quality of the evidence (including the certainty of estimates), and the nature and variability of patient values and preferences. KEY FINDINGS AND LIMITATIONS: Key recommendations emphasise the importance of thorough diagnosis, treatment, and follow-up for patients with NMIBC. The guidelines stress the importance of defining patients' risk stratification and treating them appropriately. CONCLUSIONS AND CLINICAL IMPLICATIONS: This overview of the 2024 EAU guidelines offers valuable insights into risk factors, diagnosis, classification, prognostic factors, treatment, and follow-up of NMIBC. These guidelines are designed for effective integration into clinical practice.

Cíl: Cílem této retrospektivní studie je ověřit, zda provedení vícečetné transuretrální resekce (reTUR) u pacientů s T1 uroteliálním karcinomem močového měchýře nevede ke zhoršení prognózy, dále zhodnotit význam jednotlivých prognostických faktorů při první a druhé reTUR. Metoda: Do retrospektivní studie bylo zařazeno celkem 363 pacientů s diagnózou T1 uroteliál- ního karcinomu v letech 2001 až 2022, z toho 260 pacientů podstoupilo aspoň jednu reTUR, u 103 pacientů nebyl reTUR proveden. Standartně v případě nálezu pT1 nádoru v TUR byla indikována reTUR až do doby, kdy byl výsledek histologie pT0, pTa, CIS nebo byl diagnostikován svalovinu infiltrující nádor (stadium pT2 a více). Ke srovnání jednotlivých skupin dle počtu reTUR jsme použili Kaplan-Meierovu metodu odhadu distribuční funkce přežití a Log-rank test. Vliv jednotlivých prognostických faktorů při vícečetné reTUR byl testován pomocí Coxova regresního modelu. Výsledky: Při srovnání skupin pacientů bez provedené reTUR se skupinou s jednou reTUR, se dvě- ma reTUR a se třemi a více reTUR nebyl v rámci celého souboru 363 pacientů zjištěn významný rozdíl v celkovém přežití (OS), pro nemoc specifickém přežití (DSS) a přežití bez progrese (PFS). Přežití bez recidivy (RFS) se významně prodlužovalo s počtem provedených výkonů (p = 0,02). Podání intravezikální léčby vakcínou BCG bylo v multivariantní analýze jediným z nezávislých prognostických faktorů ve vztahu k OS a PFS. U 147 pacientů s T1 uroteliálním karcinomem léčených intravezikální vakcínou BCG rovněž nebyl zjištěn významný rozdíl v OS (p = 0,72), DSS (p = 0,75), PFS (p = 0,76), ani RFS (p = 0,85) při srovnání odpovídajících skupin pacientů. Podání intravezikální léčby vakcínou BCG u pacientů s nálezem T0, Ta a CIS v reTUR významně souviselo s delším OS (p = 0,03) a PFS (p = 0,01). Nález karcinomu během první a druhé reTUR zvyšoval riziko budoucí recidivy. Závěr: Provedení další doby transuretrální resekce v případě opakovaného nálezu T1 karcinomu v reTUR je možné považovat za bezpečné. Dle našich dat, případné komplikace plynoucí z provedení další doby TUR či oddálení případné intravezikální terapie, nezhoršují OS. Nález nádoru při první a druhé reTUR je u pacientů s T1 karcinomem močového měchýře rizikem pro budoucí recidivu.
Aim: The aim of this retrospective study is to investigate whether multiple transurethral resection (reTUR) in patients with T1 urothelial carcinoma of the bladder leads to worse prognosis and to evaluate the significance of individual prognostic factors in the first and second reTUR. Methods: A total of 363 patients diagnosed with T1 urothelial carcinoma between 2001 and 2022 were included in this retrospective study, of whom 260 patients underwent at least one reTUR and 103 patients did not undergo reTUR. By default, if a pT1 tumor was found in TUR, reTUR was indicated until histology was pT0, pTa, CIS, or a muscle-infiltrating tumor was diagnosed (stage pT2 or more). We used the Kaplan-Meier survival distribution function estimation method and the log-rank test to compare each group according to the number of reTURs. The effect of individual prognostic factors in multiple reTUR was tested using Cox regression model. Results: When comparing the groups of patients without reTUR with the groups with one reTUR, two reTUR, and three or more reTUR, there was no significant difference in overall survival (OS), disease-specific survival (DSS), and progression-free survival (PFS) in the entire cohort of 363 patients. Recurrence-free survival (RFS) significantly increased with the number of procedures performed (p = 0.02). Administration of intravesical BCG vaccine was the only independent prognostic factor in multivariate analysis in relation to OS and PFS. In 147 patients with T1 urothelial carcinoma treated with intravesical BCG vaccine, there was also no significant difference in OS (p = 0.72), DSS (p = 0.75), PFS (p = 0.76), or RFS (p = 0.85) when comparing matched groups of patients. Administration of intravesical BCG vaccine in patients with T0, Ta and CIS findings in reTUR was significantly associated with longer OS (p = 0.03) and PFS (p = 0.01). Finding cancer during the first and second reTUR increased the risk of future recurrence. Conclusion: Performing an additional period of transurethral resection in case of recurrence of T1 carcinoma at reTUR can be considered safe. According to our data, potential complications resulting from performing an additional TUR period or delaying any intravesical therapy do not worsen OS. Tumor finding at first and second reTUR is a risk for future recurrence in patients with T1 bladder cancer.

V onkourologii využíváme řadu biomarkerů v diagnostice, monitoraci léčby, předpovědi relapsu či rezistence na terapii. Nejčastěji užívaným biomarkerem v onkourologii je prostatický specifický antigen (PSA) u léčby karcinomu prostaty. Další markery se uplatňují u nádorů varlat, konkrétně alfa‐fetoprotein (AFP), beta‐podjednotka lidského choriogonadotropinu (beta‐hCG) a laktátdehydrogenáza (LD). U karcinomu močového měchýře využíváme vyšetření cytologie moči, jejímž úskalím je však i přes dobrou senzitivitu a specificitu v záchytu high‐grade uroteliálního karcinomu nízká senzitivita při detekci low‐grade lézí. U ostatních onkourologických onemocnění nám však stále specifické biomarkery chybí. V současné době probíhá výzkum cirkulujících nádorových buněk (circulating tumor cells – CTC), které jsou odebírány pomocí tzv. „tekuté biopsie“ a mohly by se stát slibnými biomarkery v řadě onemocnění. V této práci podáváme přehled aktuálního využití CTC u onkourologických onemocnění.
In oncourology, we use a number of biomark‐ ers for diagnosis, monitoring treatment, predicting relapse or resistance to therapy. The most commonly used biomarker in oncourology is prostate specific antigen (PSA) in the treatment of prostate cancer. Other markers used in testicular tumours are alpha‐fetoprotein (AFP), beta‐subunit of human chorionic gonadotropin (betahCG) and lactate dehydrogenase (LD). For bladder cancer we use urine cytology test, which despite good sensitivity and specificity in detecting high‐grade urothelial carcinomas has the disadvantage of low sensitivity in detecting low‐grade lesions. However, we still lack specific biomarkers for other oncological diseases. Currently, research is being conducted on circulating tumour cells (CTCs), which are collected by a so‐called “liquid biopsy” and could be promising biomarkers for a number of diseases. In this paper, we provide an overview of the current use of CTCs in oncourological diseases.
