Light/ultrasound/magnetic-responsive nanomaterials exhibit excellent performance in imaging and therapy and play an important role in precision theranostics of tumors. In contrast to deep organs, urinary organs (such as bladder and prostate) can easily be studied via intervention mode, which has greatly brought promising applications of stimuli-responsive nanoprobes in visualized theranostics of urinary tumors. Therefore, it has been very critical to develop stimuli-responsive nanoprobes with high safety, stability, and reliability against urinary tumors. In this review, recent advances in light/ultrasound/magnetic-responsive nanoprobes in visualized theranostics of urinary tumors are summarized, including magnetic resonance/fluorescence/ultrasound/photoacoustic imaging and multimodal imaging, photothermal/photodynamic/sonodynamic therapy and combination therapy, and single-modal/multimodal-imaging-guided visualized theranostics. Finally, the future perspectives of light/ultrasound/magnetic-responsive nanoprobes against urinary tumors are also prospected.

Cisplatin (CDDP) resistance has been established to significantly impact Bladder Cancer (BCa) therapy. On the other hand, the crucial regulatory involvement of SIRT7 and EZH2 in bladder cancer development is well known. Herein, the collaborative regulatory roles and underlying mechanisms of SIRT7 and EZH2 in CDDP resistance in bladder cancer were explored.

Despite the widespread use of perirectal spacers to reduce radiation-induced rectal toxicity during prostate cancer treatment, postmarketing data reveal rare but significant complications. This case report details a severe complication of rectourethral fistula necessitating robotic pelvic exenteration with urinary and faecal diversion following perirectal spacer placement. Although SpaceOAR has been shown to reduce rectal radiation dose, the ensuing clinical benefit remains inconclusive in real-world data.

Purpose: Although total dietary protein intake has been associated with bladder cancer (BC) risk, the effect of the origin (plant or animal) and the substitutions remain to be understood. This study aimed to investigate the effect of total dietary protein, animal-based protein, plant-based protein, and their substitutions with each other on the risk of BC using a pooled analysis of 10 cohort studies.
Methods: The study was conducted within the "BLadder cancer Epidemiology and Nutritional Determinants" (BLEND) study, including 10 prospective cohort studies from several European countries, the United Kingdom, and the United States.

Background MRI-guided focal laser ablation (FLA) is a promising treatment in localized prostate cancer (PCa). MRI-guided micro-US FLA shows potential for outpatient use, but its clinical application remains unexplored. Purpose To evaluate the safety, feasibility, and 12-month functional and oncologic outcomes of MRI-guided micro-US transperineal FLA in localized PCa and to assess the accuracy of micro-US in showing lesions depicted at MRI with Prostate Imaging Reporting and Data System (PI-RADS) score of 3 or higher.
