Clinical Outcomes of Total or Partial Renal Artery Embolization in Patients with Spontaneous Renal Bleeding.

Aims: The aim of this study was to evaluate renal artery embolization in patients with spontaneous renal artery bleeding based on detailed angiographic findings and a comprehensive analysis of its efficacy and clinical outcomes.

Materials And Methods: This retrospective study evaluated the outcomes of renal artery embolization in 18 cases among 15 patients (11 men and 4 women; mean age: 57.9 years) treated for spontaneous renal bleeding at our institution between March 2017 and October 2023.

Clinical Outcomes of Transcatheter Arterial Embolization in Patients with High-grade Gross Hematuria.

Introduction: To investigate factors influencing the effectiveness and safety of super-selective embolization in patients with high-grade gross hematuria.

Materials And Methods: This retrospective, single-center study included 19 consecutive cancer patients (12 men and 7 women, mean age of 72.3 years) who had undergone TAE for intractable hematuria between January 2008 and February 2024.

Temporary Ureter Occlusion with Simultaneous Urinary Diversion via a Single-Access Route Using a 4-French Balloon Catheter and a Pigtail Nephrostomy Drainage Catheter.

: This study evaluated the efficacy and safety of temporary ureteral occlusion combined with urinary diversion using a single-access route created by inserting a balloon catheter through a pigtail nephrostomy drainage catheter. With this approach, we aimed to offer an alternative for patients with ureteral leaks who are suboptimal surgical candidates. : This retrospective study included nine patients (eight of which were bilateral cases and one was unilateral, totaling seventeen cases) who underwent the surgery between September 2023 and March 2024.

Safety and efficacy of large-bore uncovered stents for treating malignant superior vena cava syndrome.

Purpose: To investigate the safety and efficacy of large-bore uncovered stents for treating malignant superior vena cava syndrome.

Methods: This retrospective study included 115 patients (89 men, 26 women; mean age 63.2 years; range 21-83 years) who underwent endovascular large-bore (≥18 mm in diameter) uncovered stent placement between August 2015 and July 2022.

Percutaneous placement of a retrievable fully covered metal stent with anchoring flaps for the treatment of biliary anastomotic stricture following LDLT.

To investigate the outcomes following percutaneous placement of a retrievable fully covered self-expanding metal stent (fcSEMS) with anchoring flaps at proximal and distal ends for the treatment of biliary anastomotic strictures following living-donor liver transplantation (LDLT). We retrospectively reviewed the medical records of nine patients who underwent this procedure at our centre between April 2020 and March 2021. Percutaneous stent placement was technically successful in 100% patients, and all stents were successfully retrieved.

Percutaneous Ureteral Stent Insertion in Patients with Benign Uretero-Ileal Anastomosis Strictures Who Underwent Radical Cystectomy: Assessing Risk Factors for Stent Patency.

We aimed to investigate the risk factors of early double-J ureteral stent (DJUS) dysfunction rates and the long-term patency of DJUSs inserted via a percutaneous approach in patients with benign uretero-ileal anastomosis stricture (UIAS) who had undergone radical cystectomy. In this retrospective study, 63 DJUS placements were placed via a percutaneous nephrostomy tract in 42 consecutive patients between May 2020 and March 2023. The technical success rate was 100% in all patients without major complications.

Percutaneous insertion of long-covered biliary stents in patients with malignant duodenobiliary stricture.

Objective: To investigate the technical feasibility, safety, and efficacy of a long-covered biliary stent in patients with malignant duodenobiliary stricture.

Methods: This retrospective study enrolled 57 consecutive patients (34 men, 23 women; mean age, 64 years; range, 32-85 years) who presented with malignant duodenobiliary stricture between February 2019 and November 2020. All patients were treated with a long (18 or 23 cm)-covered biliary stent.

Sorafenib Combined with Chemoembolization for Locally Advanced Hepatocellular Carcinoma with Macroscopic Vascular Invasion: A Propensity Score Analysis.

The purpose of this study was to compare the efficacy and safety of transarterial chemoembolization (TACE) plus sorafenib with those of TACE alone in patients with locally advanced hepatocellular carcinoma (HCC). Treatment-naïve patients with preserved hepatic reserve (Child-Pugh score ≤ 7) who received TACE plus sorafenib ( = 91) or TACE alone ( = 109) for locally advanced HCC with macrovascular invasion were retrospectively evaluated. Propensity score matching (PSM) was used to correct selection bias, and 63 pairs were created.

Detection of Ureteral Stones in Kidney Ureter Bladder Radiography: Usefulness of Digital Post-processing.

Purpose: Kidney, Ureter, and Bladder radiography (KUB) has frequently been used in suspected urolithiasis, but its performance is known to be lower than that of Computed Tomography (CT). This study aimed to investigate the diagnostic performance of digitally KUB in the detection of ureteral stones.

Materials And Methods: Thirty patients who underwent digital KUB and CT were included in this retrospective study.

Technical success rates and reliability of spin-echo echo-planar imaging (SE-EPI) MR elastography in patients with chronic liver disease or liver cirrhosis.

Objectives: To determine the technical success rates of MR elastography (MRE) according to established gradient-recalled echo (GRE) and spin-echo echo-planar imaging (SE-EPI) sequences and to compare liver stiffness (LS) values between the sequences during expiratory and inspiratory phases in patients with chronic liver disease or liver cirrhosis.

Methods: One hundred and eight patients who underwent MRE were included in this retrospective study. MRE was performed at 3 T based on both sequences during expiration as well as inspiration.

Imaging Features of Extramammary Paget Disease of the Scrotum: A Case Report.

Extramammary Paget disease (EMPD) is a rare intraepithelial malignancy originating in areas rich in apocrine glands, such as the vulva, perineum, perianal area, scrotum, and penis. A few reports of EMPD involving the scrotum have been described in the literature. However, only few reports have described imaging features observed in patients presenting with EMPD.
