Risk factors for HUS recurrence in renal transplantation could be identified through this meta-analysis.

Background: Chronic rhinosinusitis (CRS) is a common chronic inflammatory disease. Endoscopic sinus surgery is recommended as a standard method when medical treatment fails. The effectiveness of various complementary surgical methods such as endoscopic partial middle-turbinectomy is controversial in the improvement of CRS symptoms in these patients. This study aimed to investigate the effect of endoscopic partial middle-turbinectomy on the quality of life (QOL) of patients with chronic rhinosinusitis and nasal polyps (CRSwNP) in Iran.Method: Ninety patients with CRSwNP of grades 3 and 4 were randomly assigned to either an intervention (45 patients) or control group (45 patients). In the control group, endoscopic sinus surgery without middle turbinectomy was performed and in the intervention group, endoscopic partial middle-turbinectomy was performed in addition to endoscopic sinus surgery. To evaluate the outcomes, the SNOT-22 QOL questionnaire was used, and the results were analyzed using SPSS version 24.Results: Most of the patients were male and had a mean age of 39 years. The mean SNOT-22 QOL questionnaire scores were 49.13±16.72 and 52.51±16.95 before surgery in the control and intervention groups respectively, which did not show any significant difference. In contrast, after endoscopic surgery these scores changed to 28.46±12.38 and 11.13±5.55 in the control and intervention groups, respectively< and there was a significant difference between both groups. Although there was a significant improvement in both groups, the patients in the intervention group experienced more improvement than the control group (41.4 (±16.46) vs 30.7 (±18.27), respectively Conclusion: According to this study, it appears that the use of endoscopic partial middle-turbinectomy in addition to endoscopic sinus surgery improves CRS symptoms and the QOL of patients compared with endoscopic sinus surgery alone.
