RESUMO
BACKGROUND: The diagnostic accuracy of suspicious lesions that are classified as PI-RADS 3 in multiparametric prostate magnetic-resonance imaging (mpMRI) is controversial. This study aims to assess the predictive capacity of hematological inflammatory markers such as neutrophil-lymphocyte ratio (NLR), pan-immune-inflammation value (PIV), and systemic immune-response index (SIRI) in detecting prostate cancer in PI-RADS 3 lesions. METHODS: 276 patients who underwent mpMRI and subsequent prostate biopsy after PI-RADS 3 lesion detection were included in the study. According to the biopsy results, the patients were distributed to two groups as prostate cancer (PCa) and no cancer (non-PCa). Data concerning age, PSA, prostate volume, PSA density, PI-RADS 3 lesion size, prostate biopsy results, monocyte counts (109/L), lymphocyte counts (109/L), platelet counts (109/L), neutrophils count (109/L) were recorded from the complete blood count. From these data; PIV value is obtained by monocyte × neutrophil × platelet/lymphocyte, NLR by neutrophil/lymphocyte, and SIRI by monocyte number × NLR. RESULTS: Significant variations in neutrophil, lymphocyte, and monocyte levels between PCa and non-PCa patient groups were detected (p = 0.009, p = 0.001, p = 0.005 respectively, p < 0.05). NLR, PIV, and SIRI exhibited significant differences, with higher values in PCa patients (p = 0.004, p = 0.001, p < 0.001 respectively, p < 0.05). The area under curve of SIRI was 0.729, with a cut-off value of 1.20 and with a sensitivity 57.70%, and a specificity of 68.70%. CONCLUSION: SIRI outperformed NLR and PIV in detecting PCa in PI-RADS 3 lesions, showcasing its potential as a valuable biomarker. Implementation of this parameter to possible future nomograms has the potential to individualize and risk-stratify the patients in prostate biopsy decision.

PURPOSE: To evaluate the effect of partial nephrectomy on renal function and to identify predictors of estimated glomerular filtration rate (eGFR) at 6 months after partial nephrectomy. METHODS: Medical data of 154 consecutive patients who underwent partial nephrectomy for a renal mass between January 2015 and March 2020 were retrospectively analysed. The primary outcome measure was eGFR at 6 months postoperatively. An ordinary least regression analysis using a restricted cubic spline for continuous variables was performed to examine the association between primary outcome measure and candidate predictors. RESULTS: Of the patients, 66 (42.9%) were females and 88 (57.1%) were males with a median age of 60 (range, 50 to 67) years. The median baseline eGFR was 90.40 (range, 74.96 to 102.97) mL/min/1.73 m2 , while the median eGFR at 6 months was 77.12 (range, 61.06 to 91.93) mL/min/1.73 m2 (P < .001). Baseline eGFR (regression coefficient (ß) = 22.7, 95%CI: 18.8 to 26.5, P < .001) was found to be most significant predictor with the postoperative eGFR levels at 6 months. In addition, advanced tumour size (ß = -3.17, 95%CI: -5.33 to -1.01, P < .001) and presence of hypertension (ß = -3.48, 95%CI: -6.96 to -0.003, P = .049) were also found to be inversely associated with the postoperative eGFR levels at 6 months. CONCLUSION: Baseline eGFR values, tumour size, and presence of hypertension are significant predictors of eGFR values in the mid-term in patients undergoing partial nephrectomy.

Objective: This study aims to evaluate safety of radical cystectomy (RS)+pelvic lymph node dissection (PLND)+ileal conduit urinary diversion (ICUD) in male patients aged >65 years versus ≤65 years.Materials and Methods: Eighty-five male patients who underwent RS + PLND + ICUD for bladder cancer were retrospectively analyzed. The patients were divided into two groups according to age: ≤65 years (Group 1, n = 40) versus >65 years (Group 2, n = 45). Data including baseline demographic and clinical characteristics of the patients, length of hospital stay, and complications within 90 days of surgery, and Grade ≤ II and Grade ≥ III complications according to the Clavien-Dindo (C-D) classification were recorded. Groups were compared in terms of demographic features and development of complications within 90 day after surgery statistically.Results: The median length of hospital stay was statistically significantly longer in Group 2 than Group 1 [10 (7-17) days vs. 9 (6-14) days, respectively; p < .05]. There was no statistically significant difference in the rehospitalization rate within 90 days of surgery between the groups (p > .05).Conclusion: Our study results suggest that RS + PLND + ICUD is a safe procedure in male patients aged ≥65 years.

PURPOSE: To evaluate the association between preoperative pan-immune inflammation value (PIV) and overall survival (OS) and disease-free survival (DFS) in patients who underwent radical cystectomy for non-metastatic muscle-invasive bladder cancer. METHODS: A total of 119 patients with non-metastatic muscle-invasive bladder cancer who underwent radical cystectomy at our institution between January 2014 and January 2022 were included in this retrospective study. PIV was calculated using the formula (monocyte count × neutrophil count × platelet count)/lymphocyte count. Ideal cut-off values for PIV were determined using ROC curve analysis. Kaplan-Meier analysis was used to evaluate the impact of PIV on survival outcomes. RESULTS: The mean age of patients was 65 ± 14 years, and the mean follow-up duration was 36 months. The ideal cutoff value for PIV was determined to be 406.29, and a PIV above this value was associated with poorer OS (p < 0.001) (73 months vs. 21 months) and DFS (p = 0.002) (35 months vs 19 months). Higher neutrophil-to-lymphocyte ratio (NLR) values were also associated with poorer OS (p < 0.001) and DFS (p < 0.001), with similar effectiveness to PIV. PIV was found to be significantly more effective than platelet-to-lymphocyte ratio (PLR) and systemic immune inflammation index (SII) in predicting DFS. CONCLUSION: Preoperative PIV may serve as an independent prognostic factor for OS in patients who undergo radical cystectomy with non-metastatic muscle-invasive bladder cancer. A high PIV value was associated with poorer survival outcomes. Prospective multicenter studies are needed to further validate the relationship between PIV and histopathological features of bladder cancer.

Purpose: This study aims to evaluate the educational quality and appropriateness of laparoscopic radical nephrectomy videos on YouTube using the LAParoscopicsurgery Video EducationalGuidelineS (LAP-VEGaS) criteria. It focuses on understanding the role of online resources in medical education and objectively assessing their quality. Methods: A search was conducted on YouTube™ for "laparoscopic radical nephrectomy" on August 15, 2023, leading to the selection of the first 125 videos. Videos were chosen based on length (over 1 minute), content (laparoscopic radical nephrectomy), language (English), and nonindustry sponsorship. The LAP-VEGaS criteria, encompassing 16 items under five main categories: video introduction, case presentation, procedures, outcomes, and educational content, were used for evaluation, assigning 0 or 1 point per criterion. Results: Out of 100 videos meeting the criteria, they were divided into two groups: personal uploads by expert surgeons (Group-1) and institutional uploads by hospitals and organizations (Group-2). Group-2 videos had longer durations and higher LAP-VEGaS scores. The transperitoneal approach was preferred in 88% of the videos, and 84% were right laparoscopic nephrectomies. Group-2 had significantly higher LAP-VEGaS scores (6.3 ± 2.2) compared with Group-1 (4 ± 2.1) (P < 0,001). The number of videos published over the years increased, while LAP-VEGaS scores fluctuated. Conclusion: Assessing laparoscopic radical nephrectomy videos on YouTube™ using the LAP-VEGaS criteria helped understand the role of online sources in medical education. Institutional uploads were found to be more successful in educational aspects, emphasizing the need for continuous quality review of online medical education materials. This study also guides how to evaluate and improve medical education materials on online platforms.

BACKGROUND: This study aims to evaluate video clips of hypospadias surgery on YouTube and to assess their competence for basic steps of hypospadias surgery. METHODS: The YouTube was screened for videos of hypospadias surgery between 1 December 2018 and 20 December 2018. Videos were divided into three groups based on the subjective utility checklist scores as follows: highly compatible (group 1; ≥7 points), moderately compatible (Group 2; 5-6 points), and less compatible (group 3; ≤4 points). Groups were compared statistically. RESULTS: A total of 100 videos were included in this study. The mean total score was 4.48±1.97. There were 15 (15%) videos in group 1, 42 (42%) in group 2, and 43 (43%) in group 3. There was a statistically significant difference in the total score, duration of videos, and like/dislike ratios among the groups (P<0.001, for all). There was a strong and significant correlation between the total scores and the step of glanuloplasty and skin closure (r: 0.805, P<0.001 and r: 0.770, P<0.001, respectively). CONCLUSIONS: Our study results suggest that the educational content of the videos of hypospadias surgery on YouTube is unsatisfactory. We believe that such videos must contain information regarding the surgical steps of glanuloplasty, skin closure, flap transposition, and urethroplasty and detailed information about the suture materials.
