Iatrogenic Ureterocolic Fistula in Pediatric Age Group: A Case Report and Review of the Literature.

Ureteral injury is one of the major complications related to colorectal and gynecologic procedures. Injuries are sometimes identified intraoperatively, but the diagnosis of ureteral injury is often delayed. Ureterocolic fistula is a relatively rare condition and mostly due to obstructing calculi, diverticular disease of the colon, radiotherapy, cancer, or trauma.

Pediatric metanephric adenoma with Fanconi-Bickel syndrome: a case report and review of literature.

Background: Metanephric adenoma (MA) is a rare benign renal tumor that resembles renal cell carcinoma and Wilms' tumor in radiological as well as pathological appearance. It can present at any age or gender, and it is extremely rare in the pediatric age group with less than 50 reported cases. Fanconi-Bickel syndrome (FBS) is a rare autosomal recessive disorder of carbohydrate metabolism.

Reoperation for Channel Complications in Children With Continent Cutaneous Catheterizable Channels: The Test of Time.

Objectives: To examine the durability of continent cutaneous catheterizable urinary channels (CCCC) in children and assess whether channel complications continue to arise with extended follow-up. Previous studies demonstrated that complications of CCCC cluster in the early years following surgery.

Methods: The database of a tertiary center was queried for patients≤21 years who underwent CCCC.

Does grafted tubularized incided plate improve the outcome after repair of primary distal hypospadias: A prospective randomized study?

Objective: To detect whether grafting the incised plate during Snodgrass repair would improve outcome.

Materials And Methods: Sixty patients with primary distal hypospadias were included. Patients were equally randomized using closed envelop method to either Snodgrass or grafted tubularized incised plate repair (GTIP).

Automated diabetic retinopathy detection using optical coherence tomography angiography: a pilot study.

Background: Optical coherence tomography angiography (OCTA) is increasingly being used to evaluate diabetic retinopathy, but the interpretation of OCTA remains largely subjective. The purpose of this study was to design a computer-aided diagnostic (CAD) system to diagnose non-proliferative diabetic retinopathy (NPDR) in an automated fashion using OCTA images.

Methods: This was a two-centre, cross-sectional study.

An automated approach for early detection of diabetic retinopathy using SD-OCT images.

This study was to demonstrate the feasibility of an automatic approach for early detection of diabetic retinopathy (DR) from SD-OCT images. These scans were prospectively collected from 200 subjects through the fovea then were automatically segmented, into 12 layers. Each layer was characterized by its thickness, tortuosity, and normalized reflectivity.

Classification of retinal diseases based on OCT Images.

Optical Coherence Topography (OCT) is an emerging biomedical imaging technology that offers non-invasive real-time, high-resolution imaging of highly scattering tissues. It is widely used in ophthalmology to perform diagnostic imaging on the structure of the anterior eye and the retina. Clinical studies are carried out to assess the application of OCT for some retinal diseases.

Automatic blood vessels segmentation based on different retinal maps from OCTA scans.

The retinal vascular network reflects the health of the retina, which is a useful diagnostic indicator of systemic vascular. Therefore, the segmentation of retinal blood vessels is a powerful method for diagnosing vascular diseases. This paper presents an automatic segmentation system for retinal blood vessels from Optical Coherence Tomography Angiography (OCTA) images.

COMPARISON OF 2D AND 3D VIDEO DISPLAYS FOR TEACHING VITREORETINAL SURGERY.

Purpose: To compare medical students' learning uptake and understanding of vitreoretinal surgeries by watching either 2D or 3D video recordings.

Methods: Three vitreoretinal procedures (tractional retinal detachment, exposed scleral buckle removal, and four-point scleral fixation of an intraocular lens [TSS]) were recorded simultaneously with a conventional recorder for two-dimensional viewing and a VERION 3D HD system using Sony HVO-1000MD for three-dimensional viewing. Two videos of each surgery, one 2D and the other 3D, were edited to have the same content side by side.

Perineal Hernia Is an Unusual Complication Post Perineal Bladder Neck Closure: A Case Report.

Bladder neck closure (BNC) is the ultimate bladder neck reconstruction. If reconstruction fails, closure must be considered as it gives the highest continence rate. The vast majority of BNCs are performed through an abdominal approach (either transvesical or extravesical approach), but perineal approach remains an option for BNC with considerable success rate.

Stone culture retrieved during percutaneous nephrolithotomy: is it clinically relevant?

Stone culture has been frequently investigated following percutaneous nephrolithotomy (PNL) in the last decade. We aimed to crucially define the clinical role of stone culture in modifying the treatment plan in patients with postoperative sepsis. Between June 2012 and April 2013, a total of 79 consecutive PNL procedures were included.

Wandering nematode in the vitreous cavity.

Background: Bancroftian filariasis is focally endemic in Egypt. There have been many reports of intraocular filariasis; the question of why one filarial nematode should cause ocular disease while another does not may be related to the behavior of the microfilaria and the location of the cross-reacting ocular antigen.

Methods: A 35-year-old woman with a white worm approximately 3 disk diameters in length penetrating the left macula, moving in the vitreous cavity, with a part of its length in the vitreous cavity while the rest was embedded subretinally, is described.
