RESUMEN
BACKGROUND: To assess the results of ureterorenoscopy (URS) for upper tract urolithiasis in a contemporary Australian tertiary healthcare setting. METHODS: Hospital records of all URS stone procedures performed between January 2017 and December 2018 in a metropolitan service were retrospectively reviewed. Outcome measures including stone free rates, adherence to postoperative follow-up and complications rates were recorded. RESULTS: 385 patients (387 renal units) with mean age 53.8 (range 18-89) underwent URS for stones measuring between 2 and 27 mm (median 8 mm). 465 URS were performed with 1029 total procedures performed. 48.6% of operations were performed as day cases. Complications were recorded in 9% of the 465 URS cases with 42.9% of these Clavien II or more. The representation rate to our Emergency Departments was 15.4%. Only 49.1% (201) of patients had a follow-up review with imaging to assess stone free rates. Of the 201 patients who underwent imaging, only 38.3% were stone free. Stone analysis was performed in 34.5%. CONCLUSION: Less than half of all patients were reviewed despite undergoing expensive, time consuming surgery for a condition with a high recurrence rate. In agreement with recent publications stone-free rates were low, with significant complications and representation rates. Stone surgery should be given the attention and resources equivalent to cancer surgery to improve results. LEVEL OF EVIDENCE: 2b.

BACKGROUND: Preconception diet is a proposed modifiable risk factor for infertility. However, there is no official guidance for women in the preconception period as to which dietary approaches may improve fertility. OBJECTIVE AND RATIONALE: A comprehensive synthesis of the relevant evidence is key to determine the potentially effective dietary patterns and components as well as evidence gaps, and to provide information for nutritional recommendations for couples planning a pregnancy. SEARCH METHODS: In this systematic scoping review, four electronic databases (Medline and EMBASE via Ovid processing, CAB Direct, and CINAHL via EBSCO) were searched for observational studies (prospective and retrospective cohort, cross-sectional, and case-control studies) from inception to 27 September 2021. Eligible studies included women of reproductive age during the preconception period, and evaluated exposures related to preconception diet and outcomes related to fertility. Results were synthesized using a descriptive approach. OUTCOMES: A total of 36 studies were eligible for inclusion (31 prospective, 3 cross-sectional, and 2 case-control studies) and were published between 2007 and 2022. Of the assessed dietary exposures, increased adherence to the Mediterranean diet displayed the strongest and most consistent association with improved clinical pregnancy rates. Reducing trans fatty acids (TFAs), saturated fatty acids, and discretionary food intake (fast food and sugar-sweetened beverages) were associated with improvements in live birth, clinical pregnancy rates, and related ART outcomes. The dietary components of seafood, dairy, and soy demonstrated inconsistent findings across the few included studies. WIDER IMPLICATIONS: Due to heterogeneity and the limited available literature on most exposures, there is insufficient evidence to support any specific dietary approach for improving fertility. However, following some of the dietary approaches outlined in this review (anti-inflammatory diets, reducing TFA, and discretionary food intake) are consistent with broad healthy eating guidelines, have little to no associated risk, and offer a plausible set of possible benefits. This warrants further exploration in randomized controlled trials.

There are conflicting results on the effect of diet on fertility. This study aimed to assess the effect of different dietary patterns on fertility outcomes in populations who conceive spontaneously and those requiring assisted reproductive technology (ART). A systematic search and meta-analysis were performed for studies investigating dietary patterns or whole diets in reproductive aged women requiring ART or conceived naturally. Outcomes were live births, pregnancy rates and infertility rates. In amount of 15,396 studies were screened with 11 eligible studies. Ten different diet patterns were grouped broadly into categories: Mediterranean, Healthy or Unhealthy. For the Mediterranean diet, on excluding high risk-of-bias studies (n = 3), higher adherence was associated with improved live birth/pregnancy rates in ART [OR 1.91 (95% CI 1.14-3.19, I2 43%)] (n = 2). Adherence to various Healthy diets was associated with improved ART outcomes (ProFertility diet and Dutch Dietary Guidelines) and natural conception outcomes (Fertility diet). However, due to the variability in Healthy diets' components, results were not pooled. Studies demonstrated preliminary evidence for the role of dietary patterns or whole diets in improving pregnancy and live birth rates. However, due to heterogeneity across the literature it is currently unclear which diet patterns are associated with improvements in fertility and ART outcomes.
