Bladder neck position differences on CT in patients with incidental asymptomatic urinary bladder gas: A comparative retrospective study.

Objective: To investigate the potential link between differences in bladder neck position and the occurrence of incidental asymptomatic urinary bladder gas on computed tomography (CT) scans in female patients.

Methods: CT scans reports from January 2012 to December 2023 were analyzed in this retrospective study to identify adults presenting with bladder gas. Exclusion was based on factors such as prior urological procedures, urinary tract infections (UTIs), and other potential contributors to bladder gas.

The effect of retroaortic left renal vein on lumbar osteophytes formation.

Purpose: Assess whether a Retroaortic left renal vein (RLRV) affects vertebral osteophyte formation in the lumbar spine, compared to normal anatomy left renal vein.

Methods: We conducted a retrospective case-control study. Computed tomography (CT) scans of individuals with a RLRV (study group) were compared to age- and gender-matched normal anatomy CT scans (control group).

A Prospective, Single-Arm Study to Evaluate the Safety and Efficacy of an Autologous Blood Clot Product in the Treatment of Anal Fistula.

Background: Surgical treatment of complex perianal fistula is technically challenging, associated with risk of failure, and may require multiple procedures. In recent years, several biologic agents have been developed for permanently eradicating anal fistulous disease with variable success. In this study, the treatment is an autologous whole-blood product created from the patients' blood.

Three-dimensional reconstruction of computed tomography colonography discloses anatomic features associated with colonoscopy failure.

Objectives: Three-dimensional virtual reality (3D VR) permits precise reconstruction of computed tomography (CT) images, and these allow precise measurements of colonic anatomical parameters. Colonoscopy proves challenging in a subset of patients, and thus CT colonoscopy (CTC) is often required to visualize the entire colon. The aim of the study was to determine whether 3D reconstructions of the colon could help identify and quantify the key anatomical features leading to colonoscopy failure.

Ultrasound-Tomographic Image Fusion - A Novel Tool for Follow up After Acute Complicated Appendicitis.

Background: Computerized tomography (CT) is an integral part of the follow-up and decision-making process in complicated acute appendicitis (AA) treated non-operatively. However, repeated CT scans are costly and cause radiation exposure. Ultrasound-tomographic image fusion is a novel tool that integrates CT images to an Ultrasound (US) machine, thus allowing accurate assessment of the healing process compared to CT on presentation.

Using Virtual Reality for Deep Inferior Epigastric Perforator Flap Preoperative Planning.

Unlabelled: This study was designed to compare VR stereoscopical three-dimensional (3D) imaging with two-dimensional computed tomography angiography (CTA) images for evaluating the abdominal vascular anatomy before autologous breast reconstruction.

Methods: This prospective case series feasibility study was conducted in two tertiary medical centers. Participants were women slated to undergo free transverse rectus abdominis muscle, unilateral or bilateral deep inferior epigastric perforator flap immediate breast reconstruction.

Using Augmented Reality for Intraoperative Guidance During Sacral Neuromodulation System Implantation.

Objective: The purpose of this study was to examine the feasibility of using augmented reality during lead placement for sacral nerve stimulation (SNS).

Methods: The study was a prospective case series performed in a single tertiary center. Patients with fecal incontinence or urinary retention eligible for SNS according to the American society of colon and rectal surgeon's guidelines were included.

Ultrasound-Tomographic Image Fusion: A Novel Imaging Technique for Follow-Up of Penetrating Complications of Crohn's Disease.

We herein report the first use, to our knowledge, of computed tomography-ultrasound (US) fusion technique to follow-up Crohn's disease complications. This novel technique employs real-time reconstructed fusion of previously obtained tomographic images onto the US image software, allowing accurate bedside spatial resolution, localization, and lesion characterization by US.
