There is still ongoing debate as to whether the outcome of the sling is determined by the position of the midurethral sling. In order to evaluate the potential impact of sling position on the outcomes of retropubic and transobturator sling procedures for stress urinary incontinence, it is necessary to conduct further investigations. We conducted a comprehensive search across various electronic databases such as PubMed, EMBASE, MEDLINE. Relevant data were extracted, organized in a table format, and analyzed using RevMan software for further analysis. This review comprised a total of 9 studies. The findings indicate that patients with TVT tape placement in the midurethra exhibited a slightly higher cure rate compared to those with proximal placement. Conversely, tape placement in the midurethra was associated with a significantly higher cure rate compared to distal placement [RR = 0.84, 95% CI (0.74-0.95), P < .05]. In the case of transobturator slings, tape positioning beneath the midurethra or distal urethra yielded better outcomes compared to placement near the bladder neck [RR = 0.74, 95% CI (0.57-0.94), P = .02; RR = 0.61, 95% CI (0.39-0.96), P = .03]. Based on 2D and 3D ultrasound imaging, differences in TVT placement appear to have minimal impact on the cure rate. However, the highest rate of failure after transobturator sling surgery is closely linked to the positioning.

BACKGROUND:According to published guidelines, gynecologic surgical patients should be stratified into different risk level groups to receive prophylaxis for venous thromboembolism (VTE), but the applicability of available risk assessment models (RAMs) in common gynecologic surgical patients remained to be confirmed. We aimed to validate the use of the Caprini RAM and gynecologic Caprini (G-Caprini) RAM for assessing postoperative VTE risk in gynecologic surgical patients.METHODS:The database of a randomized controlled trial (RCT) was used to select patients who underwent gynecologic surgeries for benignant and malignant diseases in five institutions in China between 2011 and 2018. The Caprini RAM version recommended by the American College of Chest Physicians (ACCP) was adopted. Participants were divided into four risk levels based on the Caprini and G-Caprini scores. For each risk level group, the incidence of VTE was calculated. The correlation between VET incidence and risk levels was assessed by Spearman's rank correlation coefficient (RS) value.RESULTS:As a result, 800 patients in the data base were analyzed with an overall VTE incidence of 5.8%. Caprini RAM showed that the percentage of patients at very low risk, low risk, moderate risk, and high risk were 0%, 4.3%, 44.4%, and 51.4%, respectively, and the VTE incidence was 2.9%, 2.3%, and 9.0%, respectively. RS value between the risk stratification and VTE incidence was 0.500 (P=0.667). G-Caprini RAM showed that the percentage of patients at very low risk, low risk, moderate risk, and high risk were 7.8%, 28.0%, 32.0%, and 32.3%, respectively, and the VTE incidence was 0.0%, 2.9%, 2.3%, and 9.0%, respectively. RS value between the risk stratification and VTE incidence was 1.000 (P<0.01).CONCLUSIONS:The G-Caprini RAM was as suitable as the Caprini RAM for VTE risk assessment in gynecologic surgical patients. The gynecologic model has the advantages of ease of use and more accurate identification of low-risk groups.

Background: The aim of this study was to investigate the application value of laparoscopic ultrasound (LU) in retroperitoneal radical nephrectomy for renal cell carcinoma with Type II inferior vena cava tumor thrombectomy (RRN-RCC-TII-IVCTT). Methods: The clinical data (operative time, length of tumor thrombus, tumor length, intraoperative bleeding, clinical stage, histological type, residual tumor tissue, and postoperative follow-up) of 6 patients who underwent LU-guided RRN-RCC-TII-IVCTT were retrospectively analyzed, and the intraoperative experience of LU was also summarized. Results: All 6 patients recovered well with liver and kidney functions returning to normal, and no tumor recurrence, metastasis, or vena cava tumor thrombus. Conclusions: LU-guided RRN-RCC-TII-IVCTT is a feasible treatment option, which locates the tumor accurately by retroperitoneal approach and provides the additional benefit of reduced intraoperative bleeding and shortened operative time, also achieving the much sought-after goal of precision.

Purpose The aim of this study was to evaluate the applicability of bedside ultrasonography for the diagnosis of deep venous thrombosis (DVT) in patients infected with corona virus disease 2019 (COVID-19) with and without treatment with low molecular weight heparin (LMWH). Methods We retrospectively analyzed the records of deceased and surviving patients in whom ultrasonography detected or not a DVT, and in whom LMWH was or not prescribed. Results The incidence of DVT is higher in the deceased (33/35) than in the surviving (22/46) patients. LMWH was administered in a larger proportion of surviving (18/22) than of deceased (18/33) patients. D-dimer concentrations decreased in patients who received LMWH in both groups. Conclusions There was a high incidence of DVT in patients who succumbed to COVID-19. Bedside ultrasonography can detect the presence of DVT as early as possible and help assessing the risk of venous thromboembolism, allowing early and reasonable use of LMWH.

Objective To explore the value of ultrasound-guided biopsy(USGB)in diagnosing benign or malignant masses.Methods The clinical and pathological dates were retrospectively analyzed from 343 patients who had underwent USGB for suspected malignant masses in our hospital. The success rate of USGB,sensitivity,specificity,misdiagnostic rate,missed diagnostic rate,positive predict value,negative predict value,Youden index(YI),positive likelihood rate,negative likelihood rate and Kappa value were calculated.Results A total of 343 lesions in 343 cases,325 lesions were definitely diagnosed and the success rate of USGB was 94.75%(325/343).Confirmed by postoperative pathology,202 lesions were diagnosed as malignant and 141 as benign.10 lesions were misdiagnosed,14 lesions were missed diagnosed,and the accuracy was 93.00%(319/343). The sensitivity,specificity,misdiagnostic rate,missed diagnostic rate,positive predict value,negative predict value,YI,positive likelihood rate and negative likelihood rate of USGB were 93.07%(188/202),92.91%(131/141),7.09%(10/141),6.93%(14/202),94.95%(188/198),90.34%(31/145),85.98%,13.12 and 0.07,respectively.The consistency of USGB and gold standard was great(Kappa=0.86).Conclusion USGB has significant value in clinical diagnosis and guiding treatment,with high puncture success rate,high accuracy in diagnosis and great consistency with gold standard.
