Objective: To compare the surgical results, complications, and satisfaction levels of patients who underwent malleable penile prosthesis implantation (M-PPI) and Ambicor penile prosthesis implantation (A-PPI). Material and methods: One hundred forty two patients who underwent penile prosthesis implantation [M-PPI (Promedon- Tube®, Cordoba, Argentina): 81, and A-PPI (American Medical Systems, Minnesota, USA): 61] between 2013-2018 were evaluated retrospectively. Patients’ age, body mass index, smoking history, etiological factors, modified “Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) Questionnaire” scores, shortening of the penis, and complications were recorded. Results: The patients who performed A-PPI implantation were younger (56.27 ± 10.81 vs. 51.47 ± 11.79, p = 0.009). The EDITS scores of 31(38.2%) patients who underwent M-PPI and 44 (72.4%) patients who underwent A-PPI were available. It was observed that the scores on the following questions were statistical significantly higher in the A-PPI group: “Overall, are you satisfied with your penile prosthesis?, How much of your expectations did penile prosthesis meet?, How often do you use your penile prosthesis?” (p = 0.05, p = 0.048, p = 0.038). No difference was observed between the groups in terms of the scores on the other three questions (p = 0.447, p = 0.326, p = 0.365). A 61.3% of patients in MPPI (19/31) group, and 56.8% of patients in A-PPI (25/44) group stated penile shortening (p = 0.417). Mean shortening was reported as 2.1 ± 0.45 cm, and 2.12 ± 0.52 cm, in M-PPI and A-PPI groups, respectively (p = 0.90). Conclusion:It is remarkable that the patients who underwent A-PPI experienced higher satisfaction with their prosthesis. Even though it has not been evidenced in the current literature data, patients who have had either M-PPI or A-PPI should be informed about the risk of penile shortening.

Introduction: To evaluate the quality of laparoscopic radical nephrectomy videos and determine the extent to which they are informative and educational for healthcare professionals. Patients and Methods: We used the YouTube^® search engine to search for the term ‘laparoscopic radical nephrectomy’ with time filters of 4–20 min (Group 1) and >20 min (Group 2) and then sorted the results uploaded chronologically before January 2023. One hundred videos were analysed for each group. The reliability of the videos was assessed using the Journal of American Medical Association (JAMA) Benchmark Criteria and DISCERN questionnaire scores (DISCERN). Educational quality was assessed using the Global Quality Score (GQS) and a 20-item objective scoring system (OSS) for laparoscopic nephrectomy. The popularity of the videos was evaluated using the video power index (VPI). Results: The mean video duration was 8.9 ± 4.3 min in Group 1 and 52.02 ± 31.09 min in Group 2 (P < 0.001). The mean JAMA (2.49 ± 0.61) and OSS scores (60 ± 12.3) were higher in Group 2 than in Group 1, while no significant difference was observed in the mean GQS (2.53 ± 0.7, 2.39 ± 0.88, respectively) between the groups (P < 0.001, P = 0.039, P = 0.131, respectively). Conclusion: While the standardisation of surgical videos published on YouTube^® and the establishment of auditing mechanisms do not seem plausible, high total OSS, periprocedural OSS, and VPI scores, and high OSS, JAMAS, GQS and DISCERN scores in long videos indicate that such videos offer a greater contribution to education.

Urinary tract infections (UTIs) and urolithiasis exhibit a complex bidirectional relationship in which microbial colonization and urinary obstruction may mutually reinforce each other. This retrospective observational study evaluated clinical and microbiological factors associated with UTI in patients with urolithiasis using a large institutional dataset. A total of 23,241 urine cultures obtained from 12,708 unique patients were analyzed, comparing individuals with and without urolithiasis. In stone-forming patients, demographic variables, urine pH, hydronephrosis, ureteral double J stent presence and indwelling duration, urinary anomalies, and stone characteristics were assessed. Logistic regression identified independent associations, and ROC analysis defined optimal risk thresholds. UTI were more frequent in the stone group (34.5%) compared with non-stone forming patients (28.9%, p < 0.001). Escherichia coli was the most common uropathogen overall, whereas Klebsiella pneumoniae, Enterococcus faecalis, and Pseudomonas aeruginosa were significantly enriched in patients with stones. Elevated urine pH (OR: 6.37; CI: 2.67–15.19; p = 0.001) and hydronephrosis (OR: 9.14; CI: 3.74–22.35; p = 0.001) were independently associated with UTI. A stent dwell time above 29.5 days was associated with infection with 85% sensitivity and 54% specificity (AUC: 0.70; CI: 0.68–0.73), and urine pH 6.2 or higher was associated with infection with 86% sensitivity and 67% specificity (AUC: 0.77; CI: 0.75–0.80). These findings underscore that urine alkalinity, obstruction, and prolonged stenting are key factors associated with infection risk, supporting the need for careful stent management and timely microbiological evaluation in patients with urolithiasis.
