Objective To study the effect of different types of renal puncture needles on the risk of bleeding after renal puncture.Methods A retrospective analysis was performed on 428 patients who under-went renal biopsy in the Third Affiliated Hospital of Chongqing Medical University and Jiulongpo District People's Hospital of Chongqing from January 2020 to December 2022.Different types of puncture needles were used to compare the occurrence of postoperative bleeding complications(hematoma,hematuria).Results The incidence of bleeding complications after renal puncture in 428 patients was 21.0％(90/428),of which the incidence of hematoma was 18.9％(81/428),the incidence of hematuria was 2.1％(9/428),the median decrease in hemoglobin(Hb)was 5 g/L,and the incidence of serious complications such as blood transfusion and interventional therapy was 0.7％(4/428).The patients with different types of renal puncture needles were grouped(16G group,18G group).There was no significant difference in baseline data and distri-bution of renal pathological types between the two groups(P＞0.05).The incidence of postoperative bleeding in 16G group and 18G group was 22.4％(52/232)and 19.4％(38/196),respectively.The incidence of hema-toma was 20.6％(48/232)and 16.8％(33/196),respectively.The incidence of hematuria was 1.7％(4/232)and 2.6％(5/196),respectively.The decrease of Hb was 6(0,16)g/L and 4(0,17)g/L,respectively.There was no significant difference(P＞0.05).There was no significant difference in the incidence of serious compli-cations such as blood transfusion,interventional therapy and Hb decrease＞10 g/L between the two groups(P＞0.05).Conclusion Ultrasound-guided renal biopsy is safe and has a low incidence of serious complica-tions.There was no significant relationship between different puncture needle types and postoperative bleeding risk.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.
