1. The influence of catheter type, the number of sutures and patient's age on percutaneous nephrostomy displacementDimitrij Kuhelj, Ana Šušteršič, Urban Zdešar, 2025, izvirni znanstveni članek Povzetek: Background. Percutaneous nephrostomy displacement results in procedure failure, reducing quality of life in patients with hydronephrosis. Scarce data about factors influencing displacement led to evaluation of our data in order to give better insight into this topic. Patients and methods. Patients admitted for percutaneous nephrostomy (PCN) exchange between March 3rd and October 3rd 2023 were included in our prospective observational study aiming to determine possible factors influencing PCN displacement. Catheter type, number of sutures and patients’ age over 70 years were analyzed. Descriptive statistics and Pearson’s chi-square test were used; value less than 0.05 was determined as statistically significant. Results. We included 57 patients (35 males; mean age 71.4 years) in the study. Loop catheters with strings were implanted 58 times and without strings 17 times. Fixation was achieved by 55 single and by 20 double sutures. 17 PCN (22.7%) were displaced in designated period. The mean time from PCN implantation to exchange was 4.16 months. Neither catheter type, number of sutures or patients’ age significantly influenced PCN displacement (chi-square 0.57, 0.34 and 0.61, respectively). Conclusions. No significant difference in PCN displacement between two types of catheters and the number of fixing sutures was detected. Elderly patients had similar rates of PCN displacements as younger ones. The most important causes of PCN displacement remained probably patients’ activity and a care for PCN during months after the implantation. Proper patients’ education and care of the PCN are possibly the keys for long-term success.

3. Pediatric interventional neuroradiology : opportunities and challengesCene Jerele, Dimitrij Lovrič, Dimitrij Kuhelj, 2023, pregledni znanstveni članek Povzetek: Pediatric interventional neuroradiology (PINR) is a relatively new field of diagnostic and therapeutic care in the pediatric population that has seen considerable advances in recent decades. However, it is still lagging behind adult interventional neuroradiology due to a variety of reasons, including the lack of evidence validating pediatric-specific procedures, the relative absence of pediatric-specific equipment, and the challenges in establishing and maintaining PINR competencies in a relatively small number of cases. Despite these challenges, the number and variety of PINR procedures are expanding for a variety of indications, including unique pediatric conditions, and are associated with reduced morbidity and psychological stigma. Continued technological advances, such as improved catheter and microwire designs and novel embolic agents, are also contributing to the growth of the field. This review aims to increase awareness of PINR and provide an overview of the current evidence base for minimally invasive neurological interventions in children. Important considerations, such as sedation, contrast agent use, and radiation protection, will also be discussed, taking into account the distinct characteristics of the pediatric population. The review highlights the usefulness and benefits of PINR and emphasizes the need for ongoing research and development to further advance this field.

4. Image-guided percutaneous drainage of abdominal abscesses in pediatric patientsDimitrij Kuhelj, Črt Langel, 2024, pregledni znanstveni članek Povzetek: Image-guided percutaneous abscess drainage (IPAD) is an effective, minimally invasive technique to manage infected abdominal fluid collections in children. It is the treatment of choice in cases where surgery is not immediately required due to another coexisting indication. The skills and equipment needed for this procedure are widely available. IPAD is typically guided by ultrasound, fluoroscopy, computed tomography, or a combination thereof. Abscesses in hard-to-reach locations can be drained by intercostal, transhepatic, transgluteal, transrectal, or transvaginal approaches. Pediatric IPAD has a success rate of over 80% and a low complication rate.
