Vooruitstrevend in maatschappelijk vastgoed
Maatschappelijk vastgoed betreft objecten die een publieke functie vervullen op het gebied van onderwijs, sport, cultuur, welzijn en zorg. Veel gemeenten in Nederland hebben het maatschappelijk vastgoed niet inzichtelijk. De gemeente Helmond heeft dit probleem aangepakt door het maatschappelijk vastgoed inzichtelijk te maken. Zij zijn bezig met het professionaliseren van het beheer van maatschappelijk vastgoed. Hiervoor is een speciaal team Vastgoed gerealiseerd. Dit team Vastgoed houdt zich bezig met de eisen en wensen van de veeleisende gebruiker van het maatschappelijk vastgoed. De gemeente Helmond wil de waardering van het vastgoed van de huurders weten en tevens haar dienstverlening meten. Door een onderzoek te houden onder de huurders zal veel informatie vergaard worden, waar de gemeente vervolgens op kan inspelen op verschillende vlakken. In dit onderzoek worden deze meningen op het gebied van; kwaliteit van het vastgoed, dienstverlening van het team Vastgoed, communicatie van het team Vastgoed, onderhoud van het vastgoed en de gebruikerswensen onderzocht. Deze meningen worden verworven doormiddel van een enquête. Met deze enquête is de evaluerende vraagtype toegepast. Analyse van de enquête geeft een antwoord op de volgende probleemstelling: Welke dienstverleningen van de gemeentelijke afdeling Vastgoed zijn het belangrijkst voor de huurders en wat bepaalt voor de huurders de kwaliteit van het vastgoed? Studentenonderzoek in het kader van het thema Leefomgeving
Fluoroscopy-use during ureterorenoscopy: are urologists concerned about radiation exposure? A nationwide survey in Belgium and The Netherlands
Introduction: To evaluate the use and awareness of radiation during URS among Belgian and Dutch urologists. Material and methods: An online questionnaire was send to all members of the Belgian and Dutch Association of Urology. Results: 170 urologists finished the complete questionnaire. 10% of the respondents are not familiar with the ALARA-principle. 29% starts with a KUB and 48% makes an XRPG at the beginning of the procedure. 85% uses fluoroscopy to place a wire or ureteral access sheet, 18% during stone treatment, 59% to screen for missed stones or calyces, 90% to place a JJ-stent or ureter-catheter and 23% to check for extravasation. 82% do not document radiation data. 51% does not wear a dosimeter during fluoroscopy. Almost all wear a lead apron during fluoroscopy, 47% uses additional thyroid shields and only 4% uses lead glasses. 88% intentionally reduces fluoroscopy time, 75% reduces the exposed area with a diaphragm, 72% brings the radiation source close to the patient and 44% uses pulsed fluoroscopy. Conclusion: There is a wide variety in the use and awareness of radiation during URS. To further reduce radiation and its negative effect for patients and medical staff, awareness about radiation safety should increase among urologists
Could the region you live in prevent or precipitate kidney stone formation due to mineral intake through tap water? An analysis of nine distribution regions in Flanders
Objectives: To analyse the mineral content of tap water in Flanders and assess if the region one lives in could prevent or precipitate stone formation due to a difference in mineral content. Methods: Data from six water companies providing tap water to nine regions in Flanders regarding calcium, magnesium, potassium, sodium and sulphate content in tap water was retrieved. Minimum and maximum values were collected and compared between the different geographical regions. Results: The highest calcium level was found in region 9 with a value of 157.0 mg/L, which is almost 10 times the value found in region 8 (16.1 mg/L). Region 6 had the highest magnesium (31.8 mg/L), potassium (30.5 mg/L), sodium (126.6 mg/L) and sulphate (218.5 mg/L) levels. The lowest level of magnesium (2.7 mg/L) was found in region 1, which was almost 12 times lower as in Region 6. Region 9 had the lowest level of potassium (1.5 mg/L), which is a factor 20 lower than Region 6. The lowest sodium and sulphate levels were found in region 8 (6.8 mg/L and 3.0 mg/L), respectively. The difference between the highest and lowest level of sulphate was a factor 70. Conclusion: There is a broad range in the minerals found in tap water between the different production sites in the nine distribution regions in Flanders. However, due to the high standards tap water has to meet in Flanders, the region one lives in will not lead to a higher or lower risk of kidney stone formation if the advised 2 to 3 L per day are consumed
Confocal laser endomicroscopy for upper tract urothelial carcinoma: Validation of the proposed criteria and proposal of a scoring system for real-time tumor grading
Purpose: Confocal laser endomicroscopy (CLE) is a fluorescence-based fiber-optic imaging technique with the potential for intraoperative grading of upper tract urothelial carcinoma (UTUC). This study aims to (1) investigate the prevalence of the previously proposed CLE criteria for bladder cancer in papillary UTUC, (2) estimate the diagnostic value of CLE for UTUC grading and (3) propose a scoring system for a more quantifiable approach of CLE-based grading of UTUC. Materials and methods: Ureteroscopic CLE was performed in patients with UTUC. Following CLE imaging, co-localized biopsies were taken for histopathologic comparison. Postoperatively, two blinded raters assessed the CLE images. Results: Fifty-three papillary UTUCs (34 low grade and 19 high grade) were imaged with CLE in 36 patients. All the previously described CLE criteria were identifiable in varying proportions. After excluding 10 non-diagnostic recordings (5 low grade and 5 high grade) due to insufficient image quality, the histopathologic grade was correctly identified with CLE in 26 low-grade UTUCs (90%) and in 12 high-grade UTUCs (86%). The most prevalent CLE criteria with the highest diagnostic potential were cellular organization, morphology and cohesiveness of cells. A scoring system was proposed with these criteria, which yielded similar diagnostic accuracies. Conclusions: Based on the previously proposed criteria, CLE enables accurate grading of papillary UTUC at a non-diagnostic rate of 19%. The most prevalent CLE criteria with the highest diagnostic potential for grading of papillary UTUC are cellular organization, morphology and cohesiveness of cells. The proposed scoring system may simplify the assessment of CLE images for UTUC grading but external validation is required
Lessons learned from the CROES percutaneous nephrolithotomy global study
The purpose of the study was to give an overview of the data derived from the CROES PCNL Global Study published previously in 25 articles. A comprehensive overview of the outcome of the CROES PCNL Global Study was made, analysed and compared with the current literature and guidelines. Percutaneous nephrolithotomy (PCNL) was predominately performed in prone position. Although the supine position claims to be favourable over the prone approach, the present study showed a longer operation time and lower stone-free rate (SFR). This might be explained by differences in definition in operation time and methods in the evaluation of residual stones. Ultrasound (US)-guided access proves beneficial in lowering puncture time and radiation exposure. Renal anomalies can safely be treated by PCNL and have similar outcomes to a normal situation. In patients with a solitary kidney, however, there is a lower SFR and more bleeding. Also, severe chronic kidney disease (CKD) patients have less favourable outcome. Morbidity and complications following PCNL are dominated by fever (10.5%) and bleeding (7.8%). A matched control analysis confirmed that antibiotic prophylaxis gives a threefold lower post-operative fever rate. In a multivariate analysis, it was elegantly demonstrated that bleeding was directly related to the size of the dilatation: the larger the bore, the higher the chance for bleeding. Elderly patients are at higher risk of complications and longer hospital stay. Overall, obese patients have similar outcome as the general population; however, super-obese (BMI > 40) patients have a higher chance of more severe complications. For the first time, this database illustrated a significant relationship between results and complications of PCNL, and caseload volume. The optimal case volume per centre appears to be 120 PCNL's/year. Finally, a nomogram has been developed that enables better patient counselling and decision-making. The CROES PCNL Global Study is the largest real-life study providing new insights into general and special conditions. Because of the vast number of patients included, rare conditions including renal anomalies, solitary kidneys and patient characteristics like severe CKD, super obesity and old age could be analysed. Besides this information, a nomogram was developed. And for the first time, the influence of caseload volume was establishe
How well tolerated is supine percutaneous nephrolithotomy?
Supine percutaneous nephrolithotomy (PCNL) has been described in 1988 and several modifications followed since. Despite claimed benefits, supine PCNL is still neglected by the majority of urologists. Lack of experience and the fear of complications are possible explanations for the resistance to supine positioning. This review evaluates recent literature on the use of supine PCNL, focussing on benefits and safety. The Clinical Research Office of the Endourological Society Global Study and several (retrospective) reports comment on efficacy and safety of PCNL, differences in techniques, or identify conditions and patient factors for best practice. Anesthesiologic benefits (especially in the high risk, cardiopulmonary compromised, patient) and anatomical advantages are described in supine position theoretically favoring safety of supine PCNL. However, there are no prospective randomized studies conducted to support this assumption. Overall, benefits in efficacy or safety, of one position over the other, are not yet proven. Supine PCNL has advantages in selected patients. Ultimately, the decision on position should be made on patient's characteristics and surgeon's preference and experienc
Diagnostic dilemmas in patients with upper tract urothelial carcinoma
Upper tract urothelial carcinoma (UTUC) is a rare condition and recommendations based on a high level of evidence for diagnosis, treatment and follow-up monitoring are lacking. Current decision-making is often based on evidence from trials investigating urothelial carcinoma of the lower tract. Radical nephroureterectomy has been the standard of care for UTUC but kidney-sparing treatment using endoscopic approaches has been established for a select patient group with low-grade and low-stage disease. Optimal treatment choice requires correct tumour characterization. According to available recommendations, diagnostic work-up of UTUC includes evaluation by CT urography or MRI urography, cystoscopy and urine cytology. Ureterorenoscopy and lesion biopsy are grade C recommendations in patients with suspected UTUC. When kidney-sparing treatment is planned, ureterorenoscopy and biopsy should be considered and are the procedures of choice in most cases. These diagnostics have limitations and their accuracy varies in defining tumour characteristics and predicting grade and stage. Urinary tests have higher sensitivity than cytology for detection of lower tract urothelial carcinoma but evidence of their benefit in UTUCs is lacking. New optical and image enhancement techniques are being developed to facilitate real-time diagnostics with increased accuracy. A new diagnostic algorithm for patients with suspected UTUC that integrates the diagnosis, treatment and clinical risk stratification is require
Validation of confocal laser endomicroscopy features of bladder cancer: The next step towards real-time histologic grading
Confocal laser endomicroscopy (CLE) is an optical imaging technique that allows for real-time in vivo microscopic imaging of bladder tissue. In this first validation of CLE features, we confirm that the proposed CLE features suffice for real-time tumour grading.Background: Cystoscopy enables the visualisation of suspicious bladder lesions but lacks the ability to provide real-time histopathologic information. Confocal laser endomicroscopy (CLE) is a probe-based optical technique that can provide real-time microscopic images. This high-resolution optical imaging technique may enable real-time tumour grading during cystoscopy. Objective: To validate and adapt CLE criteria for bladder cancer diagnosis and grading. Design, setting, and participants: Prospectively, 73 patients scheduled for transurethral resection of bladder tumour(s) were included. CLE imaging was performed intraoperatively prior to en bloc resection. Histopathology was the reference standard for comparison. Intervention: Cystoscopic CLE imaging. Outcome measurements and statistical analysis: Three independent observers evaluated the CLE images to classify tumours as low- or high-grade urothelial carcinoma (UC), or benign lesions. Interobserver agreement was calculated with Fleiss kappa analysis and diagnostic accuracy with 2 × 2 tables. Results and limitations: Histopathology of 66 lesions (53 patients) revealed 25 low-grade UCs, 27 high-grade UCs, and 14 benign lesions. For low-grade UC, most common features were papillary configuration (100%), distinct cell borders (81%), presence of fibrovascular stalks (79%), cohesiveness of cells (77%), organised cell pattern (76%), and monomorphic cells (67%). A concordance between CLE-based classification and histopathology was found in 19 cases (76%). For high-grade UC, pleomorphic cells (77%), indistinct cell borders (77%), papillary configuration (67%), and disorganised cell pattern (60%) were the most common features. A concordance with histopathology was found in 19 cases (70%). In benign lesions, the most prevalent features were disorganised cell pattern (57%) and pleomorphic cells (52%), and a concordance with histopathology was found in four cases (29%). Conclusions: The CLE criteria enable identification of UC. CLE features correlate to histopathologic features that may enable real-time tumour grading. However, flat lesions remain difficult to classify. Patient summary: Confocal laser endomicroscopy may enable real-time cancer differentiation during cystoscopy, which is important for prognosis and disease management.Cure Brain Cancer FoundationCure for Cancer Foundatio
Outcome from 5-year live surgical demonstrations in urinary stone treatment: are outcomes compromised?
To compare intra- and post-operative outcomes of endourological live surgical demonstrations (LSDs) and routine surgical practice (RSP) for urinary stones. Consecutive ureterorenoscopic (URS) and percutaneous (PNL) urinary stone procedures over a 5-year period were reviewed. Procedures were divided into LSDs and RSP. Differences between the groups were separately analysed for URS and PNL. Primary outcomes included intra- and post-operative complication rates and grades. Secondary outcomes were operation time, length of hospital stay, stone-free rate, and retreatment rate. Pearson's Chi-square analysis, Mann-Whitney U test, and logistic and linear regression were used to compare outcomes between LSDs and RSP. During the study period, we performed 666 URSs and 182 PNLs, and 151 of these procedures were LSDs. Among URSs, the overall intra-operative complication rate was 3.2% for LSDs and 2.5% for RSP (p = 0.72) and the overall post-operative complication rate was 13.7% for LSDs and 8.8% for RSP (p = 0.13). Among PNLs, the overall intra-operative complication rate was 8.9% for LSDs and 5.6% for RSP (p = 0.52) and the overall post-operative complication rate was 28.6% for LSDs and 34.9% for RSP (p = 0.40). For both URSs and PNLs, no statistically significant differences in complication grade scores were observed between LSDs and RSP. Operation time was significantly longer for LSD-URS group, but there was no difference between the PNL groups. There were no significant differences in length of hospital stay and stone-free rate. The retreatment rate was higher in the LSD-URS group compared with RSP-URS group but similar between the PNL groups. Multiple logistic regression analyses, adjusting for confounders, revealed no association between LSD and more or less favourable outcomes as compared to RSP. Live surgical demonstrations do not seem to compromise patients' safety and outcomes when performed by specialised endourologist
