A global snapshot of endourology residency training.

BACKGROUND: Urology has become more complex over the last decades with surgical sophisticated technologies such as endoscopy, laparoscopy and robotic surgery. As these minimally invasive methods gain popularity throughout the world, this has led in some countries to a serious training gap as compared to other countries, and between generations of surgeons within national training systems. There is a huge heterogeneity in urological training between countries, whether developed or developing. This paper attempts to shed some light onto global urological training, comparing a significant number of various national systems, and to outline global tendencies in urological training. It will enable interested readers to see where their own system stands in international comparison, and hopefully enable them to identify training needs to achieve global quality standards. MATERIALS AND METHODS: This is a questionnaire-based assessment which was sent to 240 members of U-merge from 62 countries. In addition, there is ample literature on the requirements of structured training programs and assessments, and we have tried to briefly outline the key points in this paper. RESULTS: We received responses from 32 countries Urology residency training is hugely heterogenous between countries. Only 44% of nations use a structured training program with assessments. Others use the Halstedian apprenticeship approach. Notably, some developing countries do use modern teaching and assessment methods, whereas some developed countries still use the outmoded apprenticeship model. For the interested reader, results have been tabled in detail, and training systems described country by country. CONCLUSIONS: Our results have shown a huge heterogeneity in quality urology training between countries and within continents. In systems without national structure of training, it can be assumed that such differences exist even between hospitals/ training institutions. There is no doubt in times of globalization with resident and doctor migration and exchanges that training needs structure and standardization. The still huge gap in developing countries to catch up and be able to afford latest surgical and learning technologies need to be addressed with the help of responsible outreach programs.

Nutrients, vitamins, probiotics and herbal products: an update of their role in urolithogenesis.

Nutrients, vitamins, probiotics, and herbal products may be risk factors, or alternately, protect against the formation of urinary stones. The purpose of this review was to update knowledge of the role of nutraceuticals in renal stone formation. A systematic search of the relevant literature published in PubMed in the last ten years was conducted and a narrative review of the data from the included studies was done. Search screened 513 studies that were reduced to 34 after evaluation by title and abstract; other 38 studies were retrieved by references of the selected studies. Beverages high fluid intake confirmed protective effect; orange juice protective effect; apple or grapefruit juice not confirmed as risk factors; sugar-sweetened soda and punch increased risk of stone formation. Energy intake: very high energy intake increased risk factor for women (especially after menopause); dietary acid load increased risk at equal levels of energy intake. Macronutrients confirmed increased risk of high protein intake. Calcium and Oxalate: calcium intake protective effect; oxalate intake only modest increase of risk in men and older women. Metal cations zinc and iron intake no clear impact on the risk of stone formation, dietary copper increased risk; manganese intake reduced risk of stone formation. Fruits and Vegetables decreased risk. Vitamins B6 intake not associated to risk of stone formation; vitamin C intake increased risk in men; vitamin D or supplemental vitamin D intake not associated to increased risk in men and younger women, suggestion of a higher risk in older women; Probiotics Gut colonization with Oxalobacter formigenes associated to lower risk of stone formation, effect of oxalate-degraders probiotics on urinary oxalate equivocal. Herbal products efficacy of some herbal products demonstrated in some trials, more investigations needed to confirm their efficacy and safety.
