We evaluated the diagnostic accuracy and safety of ureteral optical coherence tomography (OCT) under ureterorenoscopy for T staging of UTUC. <b><i>Materials and Methods:</i></b> In this study, patients with suspected UTUC were prospectively enrolled. The safety analysis set included 16 patients who underwent ureteral OCT for ureteral tumors. Because two (13%) patients underwent ureterorenoscopic ablation therapy, the diagnostic accuracy analysis set included 14 of 16 patients who had both ureteral OCT data and a final pathological T (pT) stage from surgical specimens. The concordance, underdiagnosis, and overdiagnosis rates were compared between radiographical imaging-based T (cT) and OCT-based T (octT) diagnoses. The primary outcome was the diagnostic accuracy of ureteral OCT in discriminating between pTis/Ta/T1 (non-muscle-invasive UTUC) and T2/T3 (muscle-invasive UTUC) cancers. <b><i>Results:</i></b> Concordance between cT-based and pT-based diagnoses was observed in 11 (79%) of the 14 patients, whereas a higher concordance rate (13/14, 93%) was noted for octT diagnosis. Additionally, the underdiagnosis and overdiagnosis rates of octT were 0% and 7.1%, respectively, which were lower than those of cT (7.1% and 14%, respectively). Although no intraprocedural urinary injury was observed, postprocedural complications included hematuria in five patients (31%), urinary tract pain in two (13%), and urinary tract infection in one patient (6.3%). <b><i>Conclusion:</i></b> Ureteral OCT exhibited a high diagnostic performance in discriminating between non-muscle-invasive UTUC and muscle-invasive UTUC with a safety profile.

Currently, there is no direct comparison of outcomes between percutaneous cystolitholapaxy and open cystolithotomy in this specific patient population. Thus, we sought to evaluate the therapeutic efficacy and associated morbidity of both surgical approaches in patients with EEC. <b><i>Methods:</i></b> Patients who underwent either their first percutaneous cystolitholapaxy or open cystolithotomy between 2003 and 2023 were identified using an IRB-approved institutional database of 1512 patients with EEC. <b><i>Results:</i></b> Among 66 patients, 8 (12.12%) underwent percutaneous cystolitholapaxy without augmentation, 31 (46.97%) underwent percutaneous cystolitholapaxy with augmentation, 11 (16.67%) underwent open cystolithotomy without augmentation, and 16 (24.24%) underwent open cystolithotomy with augmentation. Compared with the open approach, the percutaneous approach resulted in shorter operative times: 123 (interquartile ranges [IQR]: 81-151) <i>vs</i> 218 minutes (IQR: 142-281) for patients with augmentation, and 131 (IQR: 115.5-141) <i>vs</i> 196 minutes (IQR: 176.5-287.3) for those without augmentation (<i>p</i> = 0.0002).

We compared mFI-5 with the two most commonly used indexes, the American Society of Anesthesiologists (ASA) physical classification and the modified Charlson Comorbidity Index (mCCI), and the total number of comorbidities using the National Surgical Quality Improvement Program (NSQIP) database.

However, 3-year outcomes of CMUSs are lacking. This study aimed to evaluate the 3-year efficacy and safety of CMUSs in the maintenance treatment of refractory ureteral stricture (RUS) and explore risk factors for CMUSs-related complications. <b><i>Methods:</i></b> Between August 2018 and July 2021, 321 patients (366 renal ureter units [RUUs]) with RUS who underwent CMUSs implantation surgery were prospectively recruited in this study. A regular 3-year follow-up protocol including serum biochemistry test, abdominal imaging, and ureteral stent syndrome questionnaire was established to analyze ureteral patency and patient's quality of life (QoL). The primary ureteral patency was defined as patent ureters without CMUSs-related complications, while secondary ureteral patency also included those that restored patent after endoscopic interventions. <b><i>Results:</i></b> The study included 105 (32.7%) patients with stone-related benign ureteral stricture (BUS), 90 (28.0%) with nonstone-related BUS, 76 (23.7%) with radiation-induced ureteral stricture (RIUS), and 50 (15.6%) with malignant ureteral stricture. There existed significant differences in mean serum creatinine levels and renal pelvis widths before and after CMUSs implantation (all <i>p</i> < 0.001). Patients' QoL significantly improved at postoperative 12 and 36 months (both <i>p</i> < 0.001). CMUSs-related complications occurred in 95 (26.0%) RUUs, including 24 (6.6%) with end-stent ureteral restenosis, 28 (7.7%) with stent migration, 31 (8.5%) with stent encrustation, 7 (1.9%) with infection, and 5 (1.4%) with ureteral fistula. The 3-year primary and secondary ureteral patency rate was 74.0% and 90.4%, respectively. However, among patients with RIUS, the primary and secondary ureteral patency rates were only 54.7% and 77.4%, respectively. <b><i>Conclusion:</i></b> CMUSs are effective and safe in the 3-year maintenance treatment of RUS. Patients with CMUSs experience long-term improved QoL.

Diode-pumped thulium fiber lasers (TFLs) allow for increased pulse energy by lengthening the pulse width. As pulse width lengthens, thermal diffusion has the potential to increase temperature generation outside of an irradiated target. We test the hypothesis that extending the TFL pulse duration longer than the thermal relaxation time poses an independent risk for increased nonspecific heat generation. <b><i>Methods:</i></b> A two-dimensional numerical simulation of TFL thermal confinement was performed. Energy output and pulse duration of the SOLTIVE Premium-SuperPulsed TFL were measured. Pulse energies (1.5 J) were selected for pulse durations shorter and longer than thermal relaxation time. Temperature was measured by thermocouple positioned 1 cm lateral to the fiber tip. We compared temperature increases <i>in vitro</i> for identical dosimetries (1.5 J at 20 Hz for 300 seconds) for short (3.1 ms) <i>vs</i> long (11.8 ms) pulse durations. <b><i>Results:</i></b> TFL thermal confinement time was calculated at 11.4 ms. For any given preset (short or long), pulse width (duration) increased as pulse energy increased. For any given pulse energy, pulse duration was 3 to 4 times longer comparing short <i>vs</i> long presets. For both short and long pulse settings, temperature increased as total energy increased. The maximum temperature achieved for the long pulse width was 79.6°C <i>vs</i> 71.8°C for the short-width arm (<i>p</i> = 0.002). <b><i>Conclusion:</i></b> TFL pulse duration longer than the thermal relaxation time poses an independent risk for increased nonspecific heat generation.</p>","PeriodicalId":15723,"journal":{"name":"Journal of endourology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145040238","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}
