PURPOSE: To measure the retinal nerve fibre layer (RNFL) thickness values and investigate their associations with other parameters in healthy eyes of Black South Africans. METHODS: 600 participants with healthy eyes, of whom 305 (50.83%) were males and 295 (49.17%) were females, with a mean age of 28.15 ± 13.09 years, underwent a detailed ophthalmic examination. RNFL thickness was measured by iVue SD-OCT. RESULTS: The mean global RNFL thickness was 110...

OBJECTIVE: This study aims to demonstrate a novel laparoscopic technique of tapering megaureter without disrupting the blood supply and disconnecting the ureter. MATERIALS AND METHODS: Eight cases of primary obstructive megaureter in the age group of 14-22 years underwent laparoscopic extravesical ureteric reimplantation between August 2011 and July 2015 using our novel technique. Five patients had obstruction on left side and three on right side. Follow-up ultrasonography at 1 month and 3 months, voiding cystourethrogram (VCUG) at 3 months and intravenous urogram (IVU) at 6 months was obtained to assess the development of reflux and to look for adequate drainage of the obstructive ureter...

Urogenital tuberculosis (UGTB) is the most common form of extrapulmonary TB and is responsible for a destructive inflammation of the renal parenchyma and urinary tract often leading to the loss of kidney function. For these reasons, the early diagnosis of this disease, once considered disappeared in developed countries, is very important to establish a prompt and efficient treatment. However, the subtle and non-specific symptoms, often represented by recurrent and persistent lower urinary tract symptoms, can confound and delay the diagnosis...

BACKGROUND: Acute focal bacterial nephritis (AFBN) is a rare disease currently described only in case reports and small case series. In this study we summarize the clinical features of AFBN as has been documented in the literature and draw recommendations on the proper diagnosis and therapy. METHODS: A systematic literature review was undertaken in PUBMED, Web of Science and The Cochrane Library online databases for relevant literature on AFBN in adults. RESULTS: Literature review revealed a total of 38 articles according to our inclusion criteria, of which we could extract data from 138 cases of AFBN...

PURPOSE: To investigate the safety and efficacy of nephron-sparing surgery (NSS) in the treatment of pediatric Xp11.2 translocation renal cell carcinoma (RCC). METHODS: Clinical characteristics of 9 RCC children (7 males and 2 females) with Xp11.2 translocation who received NSS between January 1973 and December 2015 were retrospectively analyzed. The mean age was 7.8years (range: 4.5-13.5years). Xp11.2 translocation RCC was found in the left side in 4 patients and right in 5...

Wilms' tumour originates predominantly in the renal tissue; in rare cases it can also arise from extra-renal sites accounting for 0.5-1% of cases of Wilms' tumours seen. A diagnosis of extra-renal Wilms' cannot be easily established with clinical and radiological features except when the histological facts are provided. Wilms' tumours arising from extra-renal sites may not be different in clinical features, protocol of treatment and outcome from a typical intra renal Wilms' tumour. A 2-year-old boy presented with an asymptomatic abdominal swelling for 3 months...

OBJECTIVES: We reviewed the data of patients with upper urinary tract (UUT) tumors to evaluate the effectiveness of diagnostic procedures. METHODS: This retrospective study evaluated tumor characteristics, imaging procedures, epidemiological and follow-up data of 113 patients. We analyzed the importance of non-invasive and endoscopic diagnosis in addition to imaging as well as the influence of stage and grade on recurrence rate. RESULTS: Most tumors were urothelial carcinomas (92...

BACKGROUND: Ureteral stenting has been a fundamental part of various urological procedures. Selecting a ureteral stent of optimal length is important for decreasing the incidence of stent migration and complications. The aim of the present study was to develop and internally validate a model for predicting the ureteral length for ureteral stent insertion. METHODS: This study included a total of 127 patients whose ureters had previously been assessed by both intravenous urography (IVU) and CT scan...

INTRODUCTION: The most common cause of adult Giant Hydronephrosis (GH) is congenital Uretero-Pelvic Junction (UPJ) obstruction. Conventional imaging modalities, like Intravenous Urography (IVU) and Computed Tomography Urography (CTU) and radionuclide renal scan can be fallacious. Serum carbohydrate antigen 19-9 (CA19-9) is a useful tumour marker for gastrointestinal and pancreatic cancer. Only a few studies and case reports have shown raised serum levels due to benign hydronephrosis and GH...

AIMS: To compare intravenous urography (IVU) and magnetic resonance urography (MRU) in the preoperative evaluation of pelvi-ureteric junction obstruction (PUJO) in children. MATERIALS AND METHODS: A total of 35 children up to 10 years of age in whom unilateral or bilateral PUJO were suspected on ultrasonography were enrolled in this prospective study. All children underwent IVU and MRU, and the findings were compared. RESULTS: Of the 70 kidneys evaluated, 14 (20%) were not visualized on IVU because of nonexcretion of contrast, whereas all the 70 (100%) kidneys were visualized on MRU...

BACKGROUND AND OBJECTIVE: Ureteral fibroepithelial polyps (UFPs) are rare benign tumors and ureteroscopy has been used for treatment. We compared the effect of UFP by ureteroscopy combined with holmium laser or thulium laser. METHODS: Twenty-five patients with UFPs were treated in our hospital between May 2003 and April 2013. All patients received ultrasound check and intravenous urography (IVU). We performed ureteroscopy operation and found ureteral polyps, so we resected the polyps with holmium laser (12 cases) or thulium laser (13 cases)...

OBJECTIVE: To report our experience of minimally invasive percutaneous nephrolithotomy(MPCNL) in managing upper urinary tract calculi complicated with severe spinal deformity. MATERIALS AND METHODS: Between August 2001 to December 2012, 16 upper urinary calculi in 13 patients with severe spinal deformity were treated by MPCNL. Preoperative investigation of the respiratory function, evaluation of anatomy by intravenous uro¬graphy (IVU) and CT scan, and preoperative kidney ultrasonagraphy with simulation of the percutaneous puncture were performed in all patients...

PURPOSE: To compare anterior and posterior segment parameters measured with the iVue-100 optical coherence tomography (OCT) in photopic and scotopic conditions. METHODS: Central and peripheral corneal thickness, retinal nerve fiber layer and macula thickness were measured using the iVue-100 OCT in 47 healthy individuals at a higher education institution in photopic (958 lux) and scotopic (0.03 lux) conditions. RESULTS: As the lighting conditions changed from scotopic to photopic, a significant change in pupil size was noted (P < 0...

The aim of this study is to compare a portable spectral domain optical coherence tomography (SD-OCT) device with a non-portable SD-OCT for the identification of anterior chamber angle parameters based on location of Schwalbe's line (SL) and to measure their reproducibility. 99 eyes from 46 normal, healthy participants underwent imaging of the inferior iridocorneal angle with the iVue and Cirrus SD-OCT under well-controlled low-light conditions. SL-angle opening distance (SL-AOD) and SL-trabecular iris space area (SL-TISA) were measured by masked, certified graders at the Doheny Image Reading Center using customized Image J grading software...

PURPOSE: Computed tomography (CT) is the gold standard imaging modality for the diagnosis and follow-up of urolithiasis. Before the use of CT, intravenous urography (IVU) was the imaging modality of choice. CT remains contentious because of the cancer risk related to radiation exposure above a threshold level. We aimed to compare the radiation exposure dose to the average patient with urolithiasis in the era of CT with that of IVU. MATERIALS AND METHODS: Our hospital medical records database was searched for patients who presented to the Emergency Department over a 1-month period in 1990 with a diagnosis of renal colic...

Introduction. Four novices to Spectral Domain Optical Coherence Tomography (SD-OCT) image review were provided a brief lecture on the interpretation of iVue iWellnessExam™ findings (available on iVue® SD-OCT, Optovue, Inc., Fremont, CA). For a cohort of 126 (Confirmed) Normal, 101 (Confirmed) Disease subjects, iWellnessExam™ OD, OS, and OU reports were provided. Each novice independently reviewed and sorted the subjects into one of four categories: normal, retinal disease, optic nerve (ON) disease, and retinal + ON disease...
