Objective The impact of Ramadan fasting on the prevalence of renal colic (RC) remains controversial. This current study aimed to assess the correlation between Ramadan fasting, prevalence of RC and the rate of urgent endoscopic interventions due to urolithiasis. Methods This retrospective case–control study enrolled adult patients with a primary diagnosis of RC secondary to urolithiasis admitted to the emergency department during the years 2009–2019. The prevalence of RC and the rate of urgent urological interventions during Ramadan were compared with the pre- and post-Ramadan months in fasting Muslims and non-fasting non-Muslim patients. Results A total of 2781 patients with RC were included: 1014 (36.5%) were fasting Muslim and 1767 (63.5%) were non-fasting non-Muslim patients. No significant increase in RC admissions or urgent double J stent (DJS) insertions were observed between pre-Ramadan and Ramadan among fasting Muslims and non-fasting non-Muslim patients. However, fasting Muslims exhibited a significant increase of RC admissions post-Ramadan compared with Ramadan. Conclusions There was no correlation between increased RC admissions or urgent DJS insertions when fasting Muslims were compared with non-fasting non-Muslim patients during Ramadan. There were increased RC admissions during the post-Ramadan month, which might indicate a delayed effect of fasting on RC.

Objective To investigate the impact of preoperative double J (DJ) stent insertion on outcomes of retrograde semi-rigid ureteroscopy (URS) in patients with upper small and medium sized ureteral stones. Methods Between April 2018 and September 2019, we retrospectively reviewed the medical register of Hillel Yaffe tertiary reference Centre (HYMC) for patients who had undergone retrograde semi-rigid URS for urolithiasis. Patients were separated into two groups depending on whether they accepted the DJ stent placement before URS (Group A) or not (Group B). Operating time, stone clearance rate, number of ‘rescue’ DJ stents, duration of ‘rescue’ stents, complication rate and requirement for repeat URS were compared between groups. Results 318 procedures undertaken in 290 patients were included (Group A, 83 procedures in 80 patiants; Group B, 235 procedures in 210 patients). By comparison with the non-stented group, patients in the preoperative DJ stented group had a higher stone clearance rate, lower complication rate, less need for postoperative ‘rescue’ DJ stent, lower duration of ‘rescue’ stent and lower re-operative URS requirement, including application of a flexible URS. Conclusion Facilitated semi-rigid URS with upstream DJ stenting for small and medium size ureteral stones has favourable periprocedural outcomes compared with primary URS.
