Volume of residual urine as an indication for surgical treatment of benign prostatic hyperplasia

Objective To study the volume of residual urine as related to the surgical indication for BPH. Methods Urodynamic study was carried out in 103 BPH patients who were assigned to group A(no residual urine), group B( residual urine【 60 ml) and group C( residual urine 60 - 100 ml). Results Qmax, URA, DR and DI were not significantly different between group C and group B (P 】 0.05) but significantly different between group C and A or between B and A(P【0.05). Conclusion The conventional conception that surgical intervention is indicated when the residual urine being 】 60 ml should be strictly followed. Early surgical intervention should be undertaken if the bladder outlet obstruction or bladder function deteriorated by BPH causing residual urine. Other causes such as neurogenic should be ruled out before surgery. 10 refs,2 tabs.

The Clinical Effect Two Approaches of Microsurgery the Treatment for Pituitary Tumor

Objective:To analyze the effect of two approaches of microsurgery in the treatment of pituitary tumor.Methods:The main body of this study was 69 patients with pituitary tumor who came to the hospital between December 2016 and December 2019.Taking the coin method as the standard,group A underwent nasal-sphenoid sinus approach with 36 cases;group B underwent transcranial approach with 33 cases.The treatment effects were compared.Results:The total effective rate of group A was 94.44%,and that of group B was 72.73%;the therapeutic index of group A was better than that of group B;the complication rate of group A was 8.33%,and that of group B was 30.30%(P<0.05).After treatment,the tumor volume of both groups decreased,and group A was smaller than group B(P<0.05).Conclusion:Nasal-sphenoid sinus approach for patients with pituitary tumors can improve the treatment index,enhance the curative effect,reduce the size of the tumor,and have better safety.

Progress in Diagnosis and Endoscopic Treatment of Stanford B Penetrating Aortic Ulcers

Penetrating aortic ulcers is rare in clinical practice,and it is necessary to intervene in this type of aortic perforating ulcer because it can be accompanied by major arterial dissection and intermural hematoma.With the widespread application and technical advancement of follow-up thoracic aortic endovascular repair(TEVAR),endovascular treatment has become the first choice for symptomatic aortic perforating ulcers.In this review,we will review the diagnosis,diagnosis and endovascular treatment of aortic perforating ulcer.

Endoscopic submucosal dissection for colorectal neoplasms:A review

The introduction of colorectal endoscopic submucosal dissection(ESD)has expanded the application of endoscopic treatment,which can be used for lesions with a low metastatic potential regardless of their size.ESD has the advantage of achieving en bloc resection with a lower local recurrence rate compared with that of piecemeal endoscopic mucosal resection.Moreover,in the past,surgery was indicated in patients with large lesions spreading to almost the entire circumference of the rectum,regardless of the depth of invasion,as endoscopic resection of these lesions was technically difficult.Therefore,a prime benefit of ESD is significant improvement in the quality of life for patients who have large rectal lesions.On the other hand,ESD is not as widely applied in the treatment of colorectal neoplasms as it is in gastric cancers owing to the associated technical difficulty,longer procedural duration,and increased risk of perforation.To diversify the available endoscopic treatment strategies for superficial colorectal neoplasms,endoscopists performing ESD need torecognize its indications,the technical issues involved in its application,and the associated complications.This review outlines the methods and type of devices used for colorectal ESD,and the training required by endoscopists to perform this procedure.

“Treat-all”Strategy for Patients with Chronic Hepatitis B Virus Infection in China:Are We There Yet?

Chronic hepatitis B remains the primary cause of liver-related events in China.The World Health Organization set a goal to eliminate viral hepatitis as a public health threat by 2030.However,achieving this goal appears challenging due to the current low rates of diagnosis and treatment.The“Treat-all”strategy,which proposes treating all patients with detectable hepatitis B virus(HBV)DNA or even all patients with positive HBsAg,has been suggested to simplify anti-HBV treatment.In 2022,the Chinese Society of Hepatology and the Chinese Society of Infectious Diseases updated the guidelines for the prevention and treatment of chronic hepatitis B in China,expanding antiviral indications and simplifying the treatment algorithm.According to this latest guideline,nearly 95%of patients with detectable HBV DNA are eligible for antiviral treatment.This review aimed to provide a detailed interpretation of the treatment indications outlined in the Chinese Guidelines for the Prevention and Treatment of Chronic Hepatitis B(version 2022)and to identify gaps in achieving the“Treat-all”strategy in China.
