The in vivo models used porcine kidneys of six adult living female pigs under general anaesthesia to simulate URS at serially increased IRPs. For the ex vivo models, porcine kidneys were procured on ice using renal transplant protocols. The renal artery was flushed and perfused with 0.9% normal saline and the renal vein left open to collect continuous venous flow. The ureter was cannulated with a retrograde catheter and the renal pelvis was distended at incrementally greater IRPs using irrigation containing either: (i) 8% acetic acid or (ii) Escherichia coli (E. coli) solution. Venous effluent was sampled every 3 min and tested for: (i) H+ ion concentration or (ii) E. coli colony-forming units per mL.RESULTSPyelovenous backflow of electrolyte solution and E. coli bacteria was exponentially proportional to IRP. E. coli bacteraemia was present in the venous blood at 30 mmHg IRP in one of six living animals. By 60 mmHg, two animals had bacteraemia, three animals by 75 mmHg, five animals by 90 mmHg IRP, and all six animals by 120 mmHg. The in vitro laboratory studies verified these results and quantified the degree of pyelovenous backflow at each of these pressures. In vitro, increasing IRP from 30 mmHg to 60 mmHg demonstrated a threefold increase in CFU/ml of E. coli. However, increasing IRP by the same magnitude from 60 mmHg to 90 mmHg demonstrated a 60-fold increase in CFU/ml of E. coli bacteraemia, and this continued exponentially up to 200 mmHg.CONCLUSIONPyelovenous backflow increases exponentially after 60 mmHg IRP. Bacteraemia can occur at IRPs between 30 and 120 mmHg in living animals; bacteraemia occurred at an average IRP of 77 mmHg in our study.","PeriodicalId":8985,"journal":{"name":"BJU International","volume":"14 1","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seven phases were annotated: bladder drop, prostate preparation, bladder neck dissection, seminal vesicle dissection, posterior dissection, apical dissection, and vesicourethral anastomosis. A total of 808 774 video frames were extracted at 1 frame/s for training and testing. Validation was performed on 25 RARP cases using the da Vinci robotic system to assess cross‐platform generalisability. Gradient‐weighted class activation mapping was used to enhance interpretability by identifying key regions of interest for phase classification.ResultsThe CNN achieved 0.90 accuracy on the hinotori test set but dropped to 0.64 on the da Vinci dataset, thus indicating cross‐platform limitations. Phase‐specific F1 scores ranged from 0.77 to 0.97, with lower performance in the phase of seminal vesicle dissection, and apical dissection. Gradient‐weighted class activation mapping visualisations revealed the model's focus on central pelvic structures rather than transient instruments, enhancing interpretability and insights into phase classification.ConclusionsThe model demonstrated high accuracy on a single robotic platform but requires further refinement for consistent cross‐platform performance.

Patients without bone metastasis or with insufficient clinical data were excluded. The study assessed the cumulative incidence of MRONJ, as well as risk factors associated with MRONJ of any stage and severe MRONJ (Stage ≥2). Cox regression analysis was used to identify independent risk factors.RESULTSThe cumulative incidence of MRONJ at 1, 2, 3, and 6 years was 4.6%, 9.6%, 20.3%, and 51.9%, respectively. For severe MRONJ, the corresponding rates were 2.4%, 6.7%, 13.1%, and 27.9%, respectively. Multivariate analysis identified the following independent risk factors for MRONJ: extent of disease grade ≥3 (hazard ratio [HR] 2.00, P = 0.009), use of anticoagulants and/or antiplatelets (HR 2.08, P = 0.026), and a history of dental treatment within the past 6 months (HR 2.29, P = 0.003).

Key risk factors were identified, along with a modifiable factor that may reduce risk. These findings suggest that adjusting denosumab dosing schedules could help mitigate MRONJ risk, underscoring the need for personalised treatment plans and early preventive strategies.","PeriodicalId":8985,"journal":{"name":"BJU International","volume":"49 1","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144664236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analysed 18-month follow-up data to assess differences in stone-related events (SREs), including re-interventions, emergency department visits, and hospital admissions. Stone-free rates and time to stone recurrence, as determined by follow-up CT scans, were also evaluated.RESULTSThe CBCT group (n = 80) had a significantly lower detection rate of new or residual fragments >4 mm (hazard ratio [HR] 0.61, 95% confidence interval [CI] 0.38-0.97), with 29 (36%) cases during 18 months of follow-up compared to 40 (50%) cases in the conventional PCNL group (n = 80). The restricted mean (standard deviation [SD]) time to fragment detection was 420 (44) days in the CBCT group vs 318 (53) days in the conventional PCNL group. In the CBCT group, 15 (19%) cases experienced 26 SREs, compared to 23 (29%) cases with 39 SREs in the conventional PCNL group. The restricted mean (SD) time to SRE was 499 (26) days for CBCT cases, compared to 447 (39) days for conventional PCNL cases. The rate of SREs did not decrease significantly when comparing CBCT-PCNL to conventional PCNL (HR 0.61, 95% CI 0.32-1.17).CONCLUSIONThis study found 10% fewer patients with SREs in the 18-month period after PCNL with intraoperative CBCT compared to conventional PCNL. This difference is likely due to the notable increase in stone-free rates following a single PCNL with intraoperative CBCT.","PeriodicalId":8985,"journal":{"name":"BJU International","volume":"52 1","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144621988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similarly, in PCa, SLNB achieves a sensitivity of 95%, potentially reinforcing its role in nodal staging and guiding personalised treatment strategies. For RCC, BCa and TCa, SLNB is currently under investigation in trials. In RCC, detection rates seem acceptable; however, in BCa and TCa, detection rates and false‐negative rates vary, limiting its clinical usefulness. Contemporary approaches utilise various radiotracers, (fluorescent) dyes, and hybrid tracers for SLNB. Ongoing research refines tumour‐targeted LN detection, including prostate‐specific membrane antigen targeting in PCa, potential c‐MET targeting in PeC, and <jats:sup>89</jats:sup>Zr‐girentuximab in RCC.ConclusionThe use of SLNB has transformed nodal staging in PeC, influencing treatment decisions and reducing morbidity in patients undergoing surgery.
