The regular use of calcium channel blockers before flexible URS appears to facilitate primary UAS insertion: a retrospective study in a single center.

Purpose: To evaluate the effect of regular use of CCB before flexible URS for successful primary UAS insertion.

Materials And Methods: We retrospectively analyzed 209 patients who underwent flexible ureteroscopy (URS) for upper urinary tract calculi between Jan 2021 and Dec 2021. Patients were divided into two groups based on whether calcium channel blockers (CCB) were used (n = 72) or not (n = 137).

Comparison of gallium-68 somatostatin receptor and F-fluorodeoxyglucose positron emission tomography in the diagnosis of neuroendocrine tumours: A systematic review and meta-analysis.

Objective: A meta-analysis was performed to compare the diagnostic performance of gallium-68 (Ga) somatostatin receptor positron emission tomography (Ga-SSTR PET) and fluorine-18-fluorodeoxyglucose (F-FDG) PET in patients with neuroendocrine tumours (NET) and whether the two imaging modalities can be mutually substituted in clinical work.

Methods: We performed electronic literature searches of the MEDLINE, PubMed, Embase and Cochrane Library databases for English-language articles from the earliest available date of indexing through 30 July 2019. We calculated the pooled sensitivity, specificity and diagnostic odds ratios (DOR) with 95% confidence intervals (95% CI) of Ga-SSTR PET and F-FDG PET in NET.
