Prevalence of upper GI tract involvement has been increasing over the past decades. Male sex and young age at diagnosis were identified as the main predictive factors for such involvement at CD diagnosis. Involvement of upper GI tract did not result in a worse outcome.
Temporary drainage of the upper urinary tract by internal ureteral stents is a routine procedure in endourology. However, it is associated with a clear side-effect profile. Our aim was to evaluate prevention and treatment options of stent-related symptoms. We carried out a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines using MEDLINE and SCOPUS, and identified 107 appropriate records. A high number of these studies showed clear methodological limitations. Available data clearly support the use of a 1 -blockers in patients suffering from stent-related symptoms. It seems that antimuscarinic monotherapy or combination with a 1 -blockers might also play an important role, whereas the use of classical analgesics in the treatment of stent-related symptoms has not been assessed systematically within clinical trials so far. Improvements in stent design and material seem to have the potential to reduce stent-related symptoms. However, so far there is no type of stent with outstanding characteristics and clear evidence suggesting fundamental advantages compared with a standard double pigtail stent. Although stent diameter does not seem to influence patients' comfort, it seems to be beneficial to choose a proper stent-length. Coated and drug-eluting stents, as well as intravesical drug application, seem to be promising concepts to prevent stent-related symptoms, but still have to be considered as experimental approaches. Furthermore, thorough patient education has the potential to reduce the morbidity associated with ureteral stenting. Further research in the field seems to be mandatory.

<b><i>Introduction:</i></b> Patients nowadays often search video-sharing platforms for online patient education materials. Since previous assessments of urological videos were limited to English, we systematically assessed the quality of videos on treatment of benign prostatic hyperplasia (BPH), prostate cancer (PCa), and urinary stone disease (USD) in 4 different languages on YouTube using validated instruments. <b><i>Methods:</i></b> The search for videos on YouTube addressing treatment options of BPH, PCa, and USD was performed in October 2020 in English, French, German, and Italian. Assessed parameters included basic data (e.g., number of views), grade of misinformation, and reporting of conflicts of interest. Quality of content was analyzed using the validated DISCERN questionnaire. Data were analyzed using descriptive statistics. <b><i>Results:</i></b> A total of 240 videos (60 videos in each language) were analyzed. Videos on USD in English had the highest number of views (median views 271,878 [65,313–2,513,007]). The median overall quality of videos assessed showed a <i>moderate</i> quality (2.5–3.4 points out of 5 points for DISCERN item 16). Median total DISCERN score of all videos divided by language showed very similar results: English (39.75 points), French (38 points), German (39.5 points), and Italian (39 points). Comparing the different diseases, videos about BPH showed the highest median scores, especially in German language (median score 43.25 points). <b><i>Conclusions:</i></b> Videos concerning the treatment of BPH, PCa, and USD have a low to moderate quality of content, with no differences seen between the languages assessed. These findings further support the notion of improved patient information materials on video platforms such as YouTube.
To compare a customized 'suture stent' with a standard ureteric stent regarding stent-related symptoms, safety and efficacy. Materials and MethodsPatients with urolithiasis located proximal to the iliac vessel crossing, requiring stenting in preparation for secondary ureterorenoscopy (URS) were randomized to standard ureteric stenting or a suture stent. Secondary ureterorenoscopy was performed 2-6 weeks later. The Ureteral Stent Symptoms Questionnaire (USSQ) was completed after 1 week, on the day before URS and 2-6 weeks after stent removal. Stent efficacy and safety were systematically assessed. ResultsA total of 88 patients were included in the analysis. The median (range) suture stent length was 10 (5-25) cm vs 26 cm for standard stents. Operation time was longer for insertion of the suture stent (24.0 vs 14.5 min; P < 0.001). Patients with a suture stent had a significantly lower USSQ urinary symptoms score 1 week after stent insertion, adjusted for baseline symptoms by subtracting scores from the final visit without indwelling stent (mean 7.1 vs 13.7, difference À6.6, 95% confidence interval [CI] À3.4 to À9.8; P < 0.001). Prior to secondary URS (after 2-6 weeks), baseline-adjusted urinary symptoms (mean 4.7 vs 12.2, difference À7.5, 95% CI À4.5 to À10.4; P < 0.001) and pain subscores (11.5 vs 17.6, difference À6.1, 95% CI À0.7 to À11.6; P = 0.004) were significantly lower in the suture stent group. All other USSQ subscores showed no significant differences. Adverse events occurred in 15 patients and were similarly frequent in the two groups. No significant differences were found between the groups regarding ureteric access during secondary URS. ConclusionReplacement of the distal part of ureteric stents by a suture can reduce stent-associated symptoms without restrictions regarding secondary stone removal or safety.
