    Introduction: Kidney stones in pregnant is not a common emergency, but it is one that is extremely challenging to manage. There exists no previous survey, which maps the different practice patterns adopted. Our aim was to deliver a survey to evaluate the current status of practice patterns across different parts of the world regarding the management of stone disease in pregnancy. Methods: Through an iterative process, 19-item survey was devised. This contained the following five sections: (1) Demographics, (2) General items, (3) Diagnosis and Imaging, (4) Initial management, (5) Surgery. It was disseminated via social media and email chains. Results: A total of 355 responses were collected, and the majority (66.2%) reported no established hospital protocol for stones in pregnancy. Ultrasound was the most popular first line imaging choice (89.9%) but 8% would choose non-contrast CT. The latter was also chosen as second line choicer in 34.6% as opposed to magnetic resonance imaging. A large proportion (42.5%) had requested CT in pregnancy previously. With equivocal ultra sound results, only 19.4% would proceed to ureteroscopy (URS) but 40.9% would opt for CT. Twenty-four–48 hours were the most popular (37.6%) time period to observe before surgical intervention. Ureteral stent and nephrostomy were regarded as equally effective, and 6 weeks was most popular frequency for an exchange. Most do not use fetal heart rate monitoring intraoperatively. A total of 3.94% had previously performed percutaneous nephrolithotomy during pregnancy. Conclusion: Practice patterns vary widely for suspected kidney stones in pregnancy and use of CT appears increasingly popular. This includes when faced with equivocal ultrasound results and instead of proceeding to ureteroscopy. Most hospitals lack an established management protocol for this scenario.

    Objective: To develop a standardised tool to evaluate flexible ureterorenoscopes (fURS). Materials and methods: A three-stage consensus building approach based on the modified Delphi technique was performed under guidance of a steering group. First, scope- and user-related parameters used to evaluate fURS were identified through a systematic scoping review. Then, the main categories and subcategories were defined, and the expert panel was selected. Finally, a two-step modified Delphi consensus project was conducted to firstly obtain consensus on the relevance and exact definition of each (sub)category necessary to evaluate fURS, and secondly on the evaluation method (setting, used tools and unit of outcome) of those (sub)categories. Consensus was reached at a predefined threshold of 80% high agreement. Results: The panel consisted of 30 experts in the field of endourology. The first step of the modified Delphi consensus project consisted of two questionnaires with a response rate of 97% (n = 29) for both. Consensus was reached for the relevance and definition of six main categories and 12 subcategories. The second step consisted of three questionnaires (response rate of 90%, 97% and 100%, respectively). Consensus was reached on the method of measurement for all (sub)categories. Conclusion: This modified Delphi consensus project reached consensus on a standardised grading tool for the evaluation of fURS - The Uniform grading tooL for flexIble ureterorenoscoPes (TULIP) tool. This is a first step in creating uniformity in this field of research to facilitate future comparison of outcomes of the functionality and handling of fURS.
