Treatment safety was assessed by 30-day complications according to the Clavien-Dindo system and change in eGFR >30 days post-procedure...

INTRODUCTION: Urethral stricture is a common, albeit complex, condition that predominantly affects men. The aim of this study was to translate, culturally adapt, and validate the Patient-Reported Outcome Measure questionnaire for patients undergoing urethroplasty (USS-PROM) into Brazilian Portuguese using validated psychometric criteria. MATERIALS AND METHODS: The process involved translating and culturally adapting the original USS-PROM into Brazilian Portuguese (USS-PROMbr), synthesizing, back-translating, cross-culturally adapting, and analyzing the pre-final version with experts from our committee...

BACKGROUND: Success rates in endourological procedures, notably percutaneous nephrolithotomy (PCNL) and ureteroscopy (URS), have demonstrated suboptimal outcomes, leading to more reinterventions and radiation exposure. Recently, the use of intraoperative computed tomography (ICT) scans has been hypothesized as a promising solution for improving outcomes in endourology procedures. With this considered, we conducted a comprehensive systematic review and meta-analysis encompassing all available studies that evaluate the impact of the use of intraoperative CT scans on surgical outcomes compared to conventional fluoroscopic-guided procedures...

Midline prostatic cysts are infrequent and mostly asymptomatic. We presented a striking case of a giant midline cyst and detailed its diagnosis, evolution, and treatment. From this case, we offered a comparison of congenital intraprostatic midline cysts, namely, Müller's cysts and utricle cysts. A 40-year-old male experienced recurrent urinary retention. A 10 × 11 mm2 cyst in the mid-prostatic region was diagnosed through transrectal ultrasound, leading to a transperineal puncture as a minimally invasive intervention...

OBJECTIVE: We aimed to investigate the value of magnetic resonance imaging (MRI) radiomics combined with serum prostate-specific antigen (PSA) in predicting the extracapsular extension (ECE) of prostate cancer. METHODS: In total, 213 patients with prostate cancer admitted to our hospital from May 2021 to April 2023 were retrospectively enrolled as observation subjects. Based on the presence or absence of extracapsular extension, the patients were divided into occurrence (n = 70) and non-occurrence (n = 143) groups...

OBJECTIVE: To analyse the incidence and influencing factors of delirium during recovery in urological postoperative patients undergoing sevoflurane anaesthesia. METHODS: The clinical data of patients undergoing sevoflurane anaesthesia in the urology surgery department in our hospital from January 2022 to December 2022 were retrospectively analysed. The incidence of delirium during the recovery period was recorded by using the Chinese version of the Confusion Assessment Method (CAM) for Severity of Delirium after surgery, and the patients were divided into occurrence and non-occurrence groups...

OBJECTIVE: A retrospective study was performed to analyse the influencing factors of stricture recurrence after urethroplasty and to establish a predictive nomogram model. METHODS: The clinical data of patients who underwent urethroplasty in our hospital from January 2021 to June 2023 were retrospectively analysed. Depending on whether stenosis occurs six months after surgery, the patients were divided into recurrence and nonrecurrence groups. Logistic regression analysis was performed on the indicators with statistically significant differences between the two groups in single factor analysis to analyse the influencing factors of postoperative recurrence risk of stricture...

BACKGROUND: Chronic inflammation is associated with various malignant tumors. Bacterial lipopolysaccharides (LPSs) play a significant part in the event and development of prostate cancer. Dishevelled segment polarity protein 3 ( DVL3 ) is a shared component of the Wnt/β-catenin and Notch signaling pathways, which are involved in tumor progression, chemoresistance, and maintenance of stem cell-like properties. According to reports, prostatic cancer cell invasion and proliferation are mediated by toll-like receptor 4 ( TLR4 )...

PURPOSE: This study aimed to determine the influence of miR-1297 on kidney injury in rats with diabetic nephropathy (DN) and its causal role. METHODS: A DN rat model was established through right kidney resection and intraperitoneal injection of streptozotocin (STZ). Sham rats did not undergo right kidney resection or STZ injection. The DN rats were divided into the DN model and antagomiR-1297 treatment groups. Kidney morphology was observed using hematoxylin and eosin staining...

BACKGROUND: In recent years, significant attention has been directed towards long non-coding RNA NUT family member 2A antisense RNA 1 ( NUTM2A-AS1 ) for its oncogenic role in tumours. This study aimed to investigate the functional and molecular mechanisms underlying NUTM2A-AS1 in prostate cancer (PCa). METHODS: NUTM2A-AS1 , miR-376a-3p , and protein arginine methyltransferase 5 ( PRMT5 ) levels were assessed in PCa samples and matched non-cancerous prostate samples...
