In recent years, patient-derived organoids (PDOs) have emerged as a promising platform for studying cancer biology and therapeutic responses in a personalized manner. Using drug screening, PDOs facilitate the identification of novel therapeutic agents and translational treatment strategies. Moreover, their ability to model patient-specific responses to treatments holds promise for predicting clinical outcomes and guiding treatment decisions. This exploratory review aims to investigate the potential of PDOs in advancing BLCa research and treatment, with an emphasis on translational clinical approaches. Furthermore, we analyze the feasibility of deriving PDOs from minimally invasive blood and urine samples.</p><p><strong>Methods: </strong>In addition to exploring hypothetical applications of PDOs for predicting patient outcomes and their ability to model different stages of BLCa, we conducted a comprehensive PubMed search on already published data as well as comprehensive screening of currently ongoing trials implementing PDOs in precision medicine in cancer patients irrespective of the tumor entity.</p><p><strong>Key findings and limitations: </strong>While the research on BLCa PDOs is advancing rapidly, data on both BLCa PDO research and their clinical application are scarce.

Patient-derived bladder cancer organoids offer a more personalized approach to studying and treating bladder cancer, providing a model that closely resembles the patient's own tumor. These organoids can help researchers identify new treatment options and predict how individual patients may respond to standard therapies.

AMPs can serve as biomarkers and alternative antibiotics, overcoming mortality related to multidrug-resistant pathogens in urinary tract infections (UTIs). While the relevance of AMPs in UTIs has been validated and AMP drugs approved by the US Food and Drug Administration are in clinical use, information about their modification status, regulation, and mechanism of action remains sparse. Only a small fraction of sequences with potential AMP activity, predicted on the basis of known AMP characteristics, have been validated. Elucidation of the global profile of AMPs in the bladder, kidney, and urine under UTI conditions would facilitate an in-depth, disease-specific understanding of the innate immune system and the development of tailored AMP biomarkers and antibiotics. This mini-review focuses on a comprehensive strategy for global profiling and validation of AMPs in UTIs that incorporates AMP data repositories, prediction algorithms, and proteomics for healthy individuals and UTI patients.

Treatment strategies for UTI in older people generally align with those for younger people, with some exceptions. Prophylaxis is similar to that for postmenopausal women.

Urodynamic investigation (UDI) is the gold standard for assessing LUTD, but its value in identifying UTI risk factors remains underexplored. Studies have shown high rates of storage and voiding dysfunction in patients with recurrent UTIs, suggesting a causal link between LUTD and UTIs. Specific UDI findings, such as low bladder capacity, high detrusor pressures, and detrusor overactivity, have been associated with greater UTI risk, especially in kidney transplant recipients and infants. However, the current evidence is limited by the lack of control groups and therapeutic interventions, making it difficult to draw definitive conclusions.
