Abstract
PURPOSE To describe a single-center experience of placing percutaneous nephrostomy (PCN) tubes in neonates and young infants aged ≤3 months. MATERIALS AND METHODS This retrospective study evaluated PCN placement during a 19-year period. Medical records were reviewed for patient demographics, indications, procedure details, catheter-related adverse events, and outcomes. A total of 45 primary PCN insertions were attempted in 29 children (median age, 11 days [range, first day of life to 3 months]; median weight, 3.5 kg [range, 1.4-7.0 kg]). Salvage procedures resulted in 13 secondary catheters in 6 children. The most common indication was ureteropelvic junction obstruction (40.0%), and the most common urinary tract dilation classification was P3 (88.9%). RESULTS Technical success for primary placements was 95.6%; both technical failures were due to loss of access in the same patient. Of primary placements, 76.7% were electively removed, 6.9% were dislodged but not replaced, and the remaining 16.3% required salvage procedures. Mechanical adverse events occurred in 20.9% of primary and 53.8% of secondary catheters, including partial retraction, complete dislodgement, and occlusion. Urinary tract infections (UTIs) occurred in 18.6% of primary and 15.4% of secondary catheters. Urosepsis occurred in 2.3% of primary and 7.7% of secondary catheters. Median primary catheter dwell time was 41 days (range, 1-182 days) and median secondary catheter dwell time was 31 days (range, 10-107 days). CONCLUSION PCN placement in neonates and young infants has a high technical success rate, although not without particular procedural and management challenges of catheter malfunction and UTI.

Emergency Decompression of Obstructive Uropathy Using Percutaneous Nephrostomy: Disease Pattern and Treatment Outcome at Two Urology Centers in Ethiopia. Open Access Emerg Med 2022; 14:15-24. [PMID: 35046735 PMCID: PMC8761074 DOI: 10.2147/oaem.s344744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Accepted: 12/21/2021] [Indexed: 11/23/2022] Open
Abstract
Purpose Obstructive uropathy (OU) is a potentially life-threatening urologic emergency that requires urgent decompression. Percutaneous nephrostomy (PCN) is a commonly performed procedure to decompress OU. The objective of this study is to assess disease patterns and treatment outcome at two urologic centers in Ethiopia. Methods A cross-sectional study was conducted on 110 patients who underwent emergency PCN from October 1, 2019 to September 30, 2020. Data were collected by a retrospective chart review. SPSS 25 was used for analysis. Descriptive statistics and logistic regression were utilized to assess disease pattern and significant predictors. A p-value of <0.05 on multivariate logistic regression was considered statistically significant. Results Females accounted for 70% of cases and mean age at presentation was 48 ± 12.9 years. Bilateral OU was diagnosed in 60% of patients and 77.3% of obstructions occurred at the level of the ureter. Malignancies were diagnosed in >80% of patients among which cervical cancer was the commonest (37.3%) followed by bladder cancer (17.3%). Acute kidney injury (AKI) accounted for 70% of the presenting indications for PCN. Success rate after emergency PCN was 75.5% and 41.8% of the cases developed post-procedure complications. Factors that predicted successful outcome include male gender [AOR = 5.72 (1.13–28.92), 95% CI; p = 0.035], severe hydronephrosis pre-operatively [AOR = 7.12 (1.32–38.45), 95% CI; p = 0.022], and use of combined imaging (ultrasound and fluoroscope) to guide PCN [AOR = 12.91 (1.13–46.54), 95% CI; p = 0.039]. On the other hand, postoperative complication is a negative predictor [AOR = 0.26 (0.08–0.86), 95% CI; p = 0.027]. Conclusion In this study, overall success of emergency PCN is low. Presence of severe hydronephrosis predicts technical ease and better outcome of PCN. Procedures performed under ultrasound and fluoroscope guidance also improve outcome. Postoperative complication rate is high in this study and mandates strict preventive measures as it predicts unfavorable outcome.

Abstract
There is growing interest in the use of contrast-enhanced ultrasound (CEUS) in diagnostic and interventional radiology. CEUS applications in interventional radiology are performed with intravascular or intracavitary administration of microbubble-based US contrast agents to allow for real-time evaluation of their distribution within the vascular bed or in body cavities, respectively, providing additional information beyond gray-scale US alone. The most common interventional-radiology-related CEUS applications in children have been extrapolated from those in adults, and they include the use of CEUS to guide lesion biopsy and to confirm drain placement in pleural effusions and intra-abdominal fluid collections. Other applications are emerging in interventional radiology for use in adults and children, including CEUS to optimize sclerotherapy of vascular malformations, to guide arthrography, and for lymphatic interventions. In this review article we present a wide range of interventional-radiology-related CEUS applications, emphasizing the current and potential uses in children. We highlight the technical parameters of the CEUS examination and discuss the main imaging findings.

Abstract
BACKGROUND Although there are many studies on percutaneous nephrostomy in urinary obstruction management in pediatric patients, there is a limited number of studies on percutaneous antegrade ureteral stenting (PAUS) on this issue. PURPOSE To evaluate the results of fluoroscopy-guided percutaneous antegrade approach for ureteral stent placement through the nephrostomy route in children. MATERIAL AND METHODS Between October 2005 and June 2019, the medical records of children who underwent PAUS through the nephrostomy route were reviewed retrospectively. Demographic data of the patients, technical and clinical success rates, technical details, and complications of the procedure were recorded. Patients were divided and evaluated into groups according to etiology. Categorical data were analyzed by using the Pearson chi-square test. RESULTS In total, 31 patients (19 boys, 12 girls; age range = 2 months-18 years; mean age = 7.4 ± 6.01 years) and 42 procedures were included in the study. The most common underlying diseases were ureteropelvic junction obstruction (16 stents, 38.1%) and vesicoureteral reflux (13 stents, 31%). The technical and clinical success rates were 97.6% and 90%, respectively. Clinical failure (10%) was not related to gender, underlying diseases, and stent size (P > 0.05). Mean stent dwelling time was 96.43 ± 58.1 days. Complications were urinary tract infection (two procedures), stent migration (two procedures), early occlusion (one procedure), and contrast material leak after balloon dilation (one procedure). The complication rate was 14.6%. No procedure-related death was observed. CONCLUSION PAUS through the nephrostomy route in children is an effective and reliable method when surgical treatment is not feasible.

Abstract
The article is part of the series of articles on radiation protection. You can find further articles in the special section of the CVIR issue. The expanding applications of interventional procedures coupled with the potential harmful effects of ionizing radiation highlight the need to assess the delivered radiation dose and establish an effective radiation protection program, particularly in the radiosensitive pediatric population. Given the complexity and heterogeneity of interventional procedures as well as the unique characteristics of children, the management of radiation dose is proving to be quite challenging. The aim of the current article is to provide an overview of the radiation exposure in pediatric patients during interventional procedures focusing on the importance of radiation protection in the pediatric population, the reported radiation doses and the techniques of minimizing radiation dose.

Abstract
PURPOSE The purpose of this study was to evaluate the indications, technique for percutaneous nephrostomy (PCN) insertion, the complications related to PCN, duration of PCN, and outcome following PCN removal regarding the kidney function. MATERIAL AND METHODS Medical charts of 31 neonates (22 boys and 9 girls, mean age 13.9 days) treated with 43 PCN were reviewed. Collected data included indications for PCN, PCN complications, duration of PCN, and outcome of these patients by analysing the kidney function. RESULTS The indications for PCN insertion were obstructive urinary tract dilation in 24 neonates (four with associated infection), and non-obstructive urinary tract dilation with urosepsis or pyonephrosis in seven cases. Primary technical success of PCN placement using Seldinger technique was 97.7%. The following complications were reported: self-limited post-procedural bleeding into the pelvicalyceal system in two, chronic microscopic haematuria in five, and clinically manifested urinary tract infection in five children. Four PCN were dislocated. Cellulitis was present at the skin entry of 5 PCN, urinary leak in 5 PCN, and mechanical damage of 5 PCN. Eight PCN had to be replaced. Mean duration of PCN was 5 months. Kidney insufficiency was detected in 5/29 children with the mean follow-up of 3.9 years. CONCLUSIONS PCN is a safe, effective transient solution in neonates with pyonephrosis or when surgery of obstructed urinary system has to be postponed. The rate of minor complications increased with PCN duration. If kidney insufficiency is present after PCN removal, it is related to the complexity of kidney anomalies.

Abstract
Objective: To determine possible risk factors for accidental nephrostomy tube dislodgement and compare two different tube types in this context in patients with chronic catheters. Materials and Methods: We conducted a retrospective study of long-term patients with nephrostomy tube. We performed a comparative analysis, studying the possible variables that were related to catheter dislodgement. In addition, a subanalysis was also carried out comparing different catheter designs (Pigtail and Foley) in case this could be related to the dislodgement. Results: Two hundred five cases were collected. A total of 51.2% of cases had a pigtail nephrostomy and 48.8% Foley type, and accidental dislodgement occurred in 26.3% of cases. In multivariate analysis, we observed that first time nephrostomy tube placement entailed higher risk of accidental dislodgement than successive placements (odds ratio [OR] 1.95, confidence interval [CI] 1.01-3.74, p = 0.04). In the pigtail-type catheter patient subgroup, tubes placed by a resident were more prone to accidental dislodgement than those placed by an attending physician (OR 3.39, CI 1.29-8.91, p = 0.01), while first episode cases were more likely to have become dislodged than in a subsequent event (OR 3.17, CI 1.17-8.57, p = 0.02). In addition, the mean (in days) until nephrostomy tube dislodgement in cases where this occurred was 20.32 ± 3.52 for pigtail and 60.92 ± 5.15 for Foley (p < 0.01 in Kaplan-Meier's test). Conclusion: Nephrostomy tube displacement in long-term patients is a common problem. Some factors associated with the catheter could increase the risk of involuntary displacement, such as being a first event or being inserted by less experienced resident doctors. In addition, pigtail type nephrostomies tend toward accidental dislodgement earlier than Foley ones.
