The outcome of ultrasound-guided insertion of central hemodialysis catheter

Objective: To point out our experience and assess the efficacy and safety of real-time ultrasound-guided central internal jugular vein (IJV) catheterization in the treatment of hemodialysis patients. Methods: This retrospective study comprised 150 patients with end-stage renal disease (ESRD) who had real-time ultrasonography (US)-guided IJV HD catheters placed in our hospital between March 2019 and March 2021. Patients were examined for their demographic data, etiology, site of catheter insertion, type (acute or chronic) of renal failure, technical success, operative time, number of needle punctures, and procedure-related complications. Patients who have had multiple catheter insertions, prior catheterization challenges, poor compliance, obesity, bony deformity, and coagulation disorders were considered at high-operative risk. Results: All patients experienced technical success. In terms of patient clinical features, an insignificant difference was observed between the normal and high-risk groups (p-value > 0.05). Of the 150 catheters, 62 (41.3%) were placed in high-risk patients. The first-attempt success rate was 89.8% for the normal group and 72.5% for the high-risk group (p = 0.006). IJV cannulation took less time in the normal-risk group compared to the highrisk group (21.2 ± 0.09) minutes vs (35.4 ± 0.11) minutes, (p < 0.001). There were no serious complications. During the placing of the catheter in the internal jugular vein, four patients (6.4%) experienced arterial puncture in the high-risk group. Two participants in each group got a small neck hematoma. One patient developed a pneumothorax in the high-risk group, which was managed with an intercostal chest tube insertion. Conclusions: Even in the high-risk group, the real-time US-guided placement of a central catheter into the IJV is associated with a low complication rate and a high success rate. Even under US guidance, experience lowers complication rates. Real-time USguided is recommended to be used routinely during central venous catheter insertion

Safety and efficacy of percutaneous nephrolithotripsy in comorbid patients: A 3 years prospective observational study

Purpose: To report the result of percutaneous nephrolithotripsy (PCNL) via standard nephrostomy tract in a single training institution. The perioperative complications in relation to the comorbid state are particularly assessed. Patients and methods: A prospective interventional study between January 2019 to November 2022, included 210 patients scheduled for PCNL. The average age was 40.3 ± 11.8 years (range 18- 67 years). Patients were categorized into two groups. The first group comprised 146 cases (69 .5%) with no associated co-morbidities while the second group 64 (30.5%) had co-morbidities such as obesity in 4 cases (1.9%), hypertension (HTN) in 24 cases (11.4%) cases, diabetes mellitus (DM) in 17 (8.1%) cases, history of recurrent stone surgery in 11 (5.2%) cases and more than one in 8 cases (3.8%). Co-morbidities, stone burden, location of stone, time of surgery, stay in the hospital, further operations, and negative events were among the reported data. Complications and the stone-free rate were the main outcome indicators. Results: Intraoperative complications were reported in 40 (18.8%) patients (18 group 1 and 22 group 2) during PCNL. Bleeding occurred in 22 (10.5%) patients (9 group 1 and 13 group 2), blood transfusions were needed in 4 (1.9%) (2 group 1 and 2 group 2), extravasation was observed in 11 patients (5.2%) (6 group 1 and 5 group 2) and cardiac arrhythmia in 3 (1.4%) (1 group 1 and 2 group 2) patients. Postoperative complications occurred in 61 patients (29%) (24 group 1 and 37 group 2) in the form of fever in 10 patients (4.8 %) (3 group 1 and 7 group 2) and prolonged leakage in 50 patients (23.8%) (21 group 1 and 29 group 2). One patient of group 2 died from postoperative sepsis. Extravasation and postoperative leakage were higher in diabetic patients than in non-diabetics. Stonefree rate was 60.5% (127 of 210). Clinically significant residual fragments (CSRFs) found in 70 cases (33.3%) (33 group 1 and 37 group 2). In 13 cases (6.2%) (5 group 1 and 8 group 2), clinically insignificant residual fragments (CIRFs) were found. In 8 (3 group 1 and 5 group 2) of the 13 cases, spontaneous stone passage was observed within 4-6 weeks of surgery. Residual stones in three cases (1 group 1 and 2 group 2) were asymptomatic and 4 mm or less, whereas stones increased in two cases of group 2. Among all factors studied, stone burden was significantly correlated to both intraoperative and postoperative complications. The occurrence of postoperative fever increased with large stone burden. Conclusions: PCNL is a therapeutic modality that is effective, feasible, and safe for a wide range of patients with concurrent medical issues. A steep curve is required to reduce intraoperative and postoperative complications
