Purpose: To present the indications, technique, complications, and contraindications for CT-guided percutaneous nephrostomy (PCN) as an alternative to standard fluoroscopy-guided puncture that involves no radiation exposure for the radiologist.
Patients And Methods: Between June 2000 and July 2004, 258 percutaneous CT-guided nephrostomies were performed in 215 patients in our department. Most patients (201; 93%) underwent PCN for obstructive uropathy, while 14 (7%) required the procedure as treatment for nonobstructive bladder trauma. All patients had subsequent insertion of a nephrostomy tube under CT guidance.
Results: Percutaneous access was achieved without major complications in all patients. The most common complication was pain at the puncture site. In 50 patients (23%), the nephrostomy catheter remained in place until full decompression of the obstruction. In the 14 patients with bladder trauma, the catheter was removed after trauma repair. In 151 patients (70%), the catheter's placement was permanent.
Conclusion: Percutaneous CT-guided nephrostomy is a reliable, safe, fast, and highly effective method associated with a low complication rate that involves no radiation for the interventional radiologist.

Percutaneous transthoracic puncture of small pulmonary nodules is technically challenging. We developed a novel electromagnetic navigation puncture system for the puncture of sub-centimeter lung nodules by combining multiple deep learning models with electromagnetic and spatial localization technologies. We compared the performance of DL-EMNS and conventional CT-guided methods in percutaneous lung punctures using phantom and animal models.

Left atrial masses are most commonly diagnosed as myxomas. When clinicians doubt the diagnosis, a biopsy is warranted. However, this can be very difficult with left-sided tumors.

Objective: To assess tumour factors that reduce primary technical efficacy (PTE) from CT-guided renal cryoablation.
Methods: Patients were taken from the EuRECA registry between December 2014 and November 2020. To focus on tumour factors rather than individual technique, this study was limited to cases using CT and excluded procedures using cone beam, US, MRI, or laparoscopy.
First Experiences with Fusion of PET-CT and MRI Datasets for Navigation-Assisted Percutaneous Biopsies for Primary and Metastatic Bone Tumors.

The aim of this study was to compare the technique of navigation-assisted biopsy based on fused PET and MRI datasets to CT-guided biopsies in terms of the duration of the procedure, radiation dose, complication rate, and accuracy of the biopsy, particularly in anatomically complex regions. Between 2019 and 2022, retrospectively collected data included all navigated biopsies and CT-guided biopsies of suspected primary bone tumors or solitary metastases. Navigation was based on preoperative CT, PET-CT/-MRI, and MRI datasets, and tumor biopsies were performed using intraoperative 3D imaging combined with a navigation system.

Objective: To evaluate the postoperative complications and prognosis of renal cell carcinoma (RCC) in a solitary kidney after irreversible electroporation (IRE).
Materials And Methods: A total of 8 patients with 9 RCCs in a solitary kidney treated with computed tomography (CT)-guided IRE from February 2017 to September 2020 were retrospectively analyzed. Follow-up included contrast-enhanced CT or magnetic resonance imaging examinations at 1 day, 1 week, 1 month, 3 months, 6 months, 12 months, and each year after IRE and the evaluation of the incidence of postoperative complications, renal function changes, local tumor recurrence, and metastasis.
