Objective. The objective is to explore the clinical application value of ultrasound long- and short-axis planar technology in real-time guided puncture in minimally invasive percutaneous nephrology. Methods. The clinical data of 80 patients undergoing real-time ultrasound-guided minimally invasive percutaneous nephrolithotomy from September 2018 to October 2019 were analyzed. The patients were randomly divided into 2 groups with different ultrasound-guided puncture techniques, long-axis in-plane technique and short-axis out-of-plane technique. Results. Minimally invasive percutaneous nephrolithotomies under real-time ultrasound guidance were successfully completed in both groups of patients. The success rate of the first puncture in the short-axis out-of-plane group was significantly higher than that in the long-axis in-plane group, and the differences were statistically significant ( P <.05); the total puncture time in the short-axis out-of-plane group was significantly less than the long-axis in-plane group, and the differences were statistical significance ( P <.05); there was no significant difference in the single-stage stone removal rate, total percutaneous renal channels, total hospital stay, and rate of complications by the Clavien classification between the 2 groups ( P > .05). Conclusion. Ultrasound long-axis and short-axis planar technologies can achieve good clinical application results in real-time guided puncture to establish percutaneous renal channels during minimally invasive percutaneous nephrolithotomy. Compared with the long-axis in-plane technique, the short-axis out-of-plane technique can shorten the puncture time and improve the success rate of the first puncture.

Objective: The purpose of this study was to assess the feasibility of in utero stem cell transplantation of human umbilical cord blood stem cells in fetal sheep and to compare two different techniques of in utero transplantation, namely ultrasound-guided in utero transplantation and in utero transplantation after midline celiotomy. Study design: Umbilical cord blood units were collected from term deliveries, after obtaining written informed consent. Human cord blood–derived, CD34+ stem cells were injected into the peritoneal cavity of 60- to 65-day-old ovine fetuses by using 2 different techniques: ultrasound-guided transabdominal percutaneous needle puncture and midline celiotomy with the exposure of the pregnant uterus. Engraftment was determined after birth by flow cytometry with use of human-specific anti-CD 34/45 antibodies. Results: We obtained a total of 3 chimeric lambs. Using the midline celiotomy technique the fetal loss rate was 75% and only 33,3% when using ultrasound-guided transabdominal percutaneous needle puncture technique. Engraftment of donor cells was found in all fetuses, with a mean level of 1.4% in fetal peripheral blood and 3.3% in fetal bone marrow. Conclusion: This preliminary study indicates that in utero stem cell transplantation of human hematopoietic cord blood stem cells in fetal lambs is feasible and effective in terms of hematopoietic engraftment. We also concluded that the ultrasound-guided transabdominal percutaneous needle puncture technique is more effective than performing a midline celiotomy in terms of fetal loss rate.

Objective This meta-analysis was performed to evaluate the safety and efficacy of the oblique-axis plane in ultrasound-guided internal jugular vein puncture. Methods We searched Embase, PubMed, the Cochrane Library, Web of Science, and China National Knowledge Infrastructure for relevant randomized clinical trials comparing the oblique axis with the short axis in ultrasound-guided internal jugular vein puncture. Results Five randomized clinical trials were included in this meta-analysis. The pooled meta-analysis showed that the incidence of arterial puncture in the oblique-axis group was significantly lower than that in the short-axis group. No significant difference was found in the first-pass success rate between the oblique-axis group and short-axis group. Additionally, there were no significant differences in the puncture success rate or number of attempts required between the two groups. Conclusion Ultrasound-guided internal jugular vein puncture using the oblique-axis plane reduced the risk of arterial puncture, but no difference was found in the first-pass success rate, puncture success rate, or number of attempts required.

Background With endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), guidewire manipulation might be a critically limiting step for nonexperts. However, the causes of difficult guidewire manipulation remain unclear. The aim of this study was to evaluate factors associated with successful guidewire manipulation. Methods This retrospective cohort study included consecutive patients who underwent EUS-HGS between October 2018 and October 2019. We measured scope angle between the long and needle axes of the echoendoscope using still fluoroscopic imaging immediately after puncturing the intrahepatic bile duct. Factors associated with successful guidewire insertion were assessed by multivariable analysis using logistic regression. Result The influence of the angle between the fine-needle aspiration (FNA) needle and echoendoscope on failed guidewire insertion was assessed using receiver operating characteristic (ROC) curves. Area under the ROC curve was 0.86 (95 % confidence interval [CI] 0.00 – 0.76), and an angle of 135° offered 88.0 % sensitivity and 82.9 % specificity for predicting successful guidewire insertion. According to multivariable analysis, only angle between the FNA needle and echoendoscope > 135° was independently associated with successful guidewire insertion (odd ratio 0.03, 95 %CI 0.01 – 0.14; P < 0.05), whereas sex, puncture site, and diameter of puncture site were not significant factors. After multivariable analysis, all variables were adjusted using age ≥ 70 or < 70 years, yielding the same results. Conclusion The angle between the FNA needle and echoendoscope might be associated with successful guidewire manipulation during EUS-HGS. Adjusting this angle to 135° before puncturing the intrahepatic bile duct might be helpful in achieving successful guidewire manipulation during EUS-HGS.
