RESUMO
Human papillomavirus (HPV) infections, primarily transmitted through sexual contact, have been linked to various cancers, including cervical, penile, anal, oropharynx, breast, and prostate cancers. This study presents a unique case of concurrent high-risk HPV35, HPV45, and HPV59 infections in both prostate and bladder cancer tissues from a single patient, representing the first documented instance worldwide with identical HPV types detected in two adjacent organs of the same individual. Employing a multiplex-PCR approach, gel electrophoresis, and Sanger sequencing, we confirmed the presence of these high-risk HPV types. Additionally, Western blot analysis using an HPV E7 antibody demonstrated the active expression of HPV oncoproteins in both cancer types. This discovery underscores the potential for HPV intra-organ transmission and necessitates further exploration of alternative transmission routes. The implications of our results offer new insights into the complex dynamics of HPV transmission in cancer pathogenesis. In conclusion our study reveals concurrent HPV infections in both prostate and bladder cancers within a single patient and highlights the potential intra-organ spread of HPV and the need for further investigation of alternative transmission routes.
RESUMO
Human papillomavirus (HPV), an oncogenic DNA virus, is the most common sexually transmitted virus and significant public health concern globally. Despite the substantial prevalence of HPV infection among men, routine testing remains elusive due to the lack of approved HPV tests and the complexity of detection methods. Various studies have explored the link between HPV and genitourinary cancers, revealing different associations influenced by geographic variation, histological subtype and methodological differences. These findings underscore the importance of further research to elucidate the role of HPV in male urogenital cancers. This comprehensive review delves into the intricate relationship between HPV and male genitourinary cancers, shedding light on the virus's oncogenic mechanisms and its reported prevalence. A deeper understanding of HPV's implications for male health is essential for advancing public health initiatives and reducing the burden of urogenital cancers worldwide.

Oxidative stress is defined as an imbalanced state of the production of reactive oxygen species and antioxidant capacity that causes oxidative damage to biomolecules, leading to cell injury and finally death. Oxidative stress mediates the development and progression of several cancer diseases, including bladder cancer. The aim of our study was to determine markers of levels of the oxidative stress in serum and urine in the same patients in parallel in serum and urine. Furthermore, we tried to estimate the associations between oxidative stress markers and the type of cancer, its clinical stage and grade, as the well as correlations between serum and urinary markers in patients with bladder cancer. Sixty-one bladder cancer and 50 healthy volunteers as a control group were included. We determined the serum and urine levels of advanced oxidation protein products (AOPP), Amadori products, total antioxidant capacity, total oxidant status (TOS), oxidative status index (OSI), and malondialdehyde. We confirm that almost all markers are elevated in serum and urine from patients with bladder cancer than from healthy subjects. Moreover, we did not find differences in the level of oxidative stress markers and the type of tumor, its clinical stage, and grade. We noted correlations between serum and urinary biomarkers, in particular TOS and OSI. Our results clearly indicate the participation of oxidative stress in the development of bladder cancer.
RESUMO
Urogenital cancers are frequently encountered in daily practice. Prostate cancer is the second most common type in adult males, and 2-3% of all adult cancers are renal cell carcinoma. Kaposi's sarcoma originates from vascular endothelial cells and is the most common type of sarcoma observed in HIV-positive patients. However, the development of all these types of cancer in a patient without immunodeficiency is very rare. Incidence of urological malignancies increase with aging. In contrast to normal population, patient who have one urological malignancy have increased risk of getting another urological malignancy in a follow-up. So follow-up of this kind of patients is crucial and needs to be done carefully. In this case report, we aimed to discuss a 68-year-old patient who was diagnosed with concurrent prostate and kidney cancer and developed penile Kaposi's sarcoma in follow-up.

Candidates for a kidney transplantation must undergo a complete evaluation, including a urological evaluation. This urological assessment should first of all exclude any pathology of the urinary tract likely to contraindicate a transplantation or to evolve under immunosuppression. Moreover, this assessment should evaluate the lower urinary tract that is to receive a kidney graft. It is therefore necessary to detect and possibly treat uro-genital cancers, benign uropathies of the native kidneys or abnormalities of the lower urinary tract. The basic evaluation is rather simple and non-invasive and includes a complete history, general and urogenital physical examination, urinalysis, total serum PSA measurement, urinary tract ultrasound, and uroflowmetry. If necessary, other explorations and testings will be carried out, such as CT scan, MRI, retrograde uretero-pyelography, uretero-renoscopy, cystoscopy, urethro-cystography or urodynamic examination. This article reviews the various pathologies involved, and sets out practical recommendations for explorations to be performed.
Les candidats à une transplantation rénale doivent faire l'objet d'une évaluation complète, y compris urologique. Ce bilan urologique permet, tout d'abord, d'exclure toute pathologie de l'arbre urinaire susceptible de contre-indiquer une greffe rénale ou susceptible de s'aggraver sous immunosuppression. Par ailleurs, ce bilan permet d'évaluer l'aptitude du bas appareil urinaire à recevoir un greffon. Il convient donc de dépister et, éventuellement, de traiter les cancers uro-génitaux, les uropathies bénignes des reins natifs ou les anomalies du bas appareil urinaire. L'évaluation de base est simple et non invasive et comprend une anamnèse complète, un examen clinique général et uro-génital, une analyse d'urine, un dosage de PSA sérique total, une échographie des voies urinaires, et une débitmétrie. Elle sera complétée par d'autres explorations si nécessaire, telles que le scanner, l'IRM, l'urétéro-pyélographie rétrograde, l'urétéro-rénoscopie, la cystoscopie, l'urétro-cystographie rétograde et permictionnelle, ou l'examen urodynamique. Cet article revoit les différentes pathologies urologiques concernées, et définit des recommandations pratiques concernant les explorations à envisager.
