INTRODUCTION: Bladder tumor is a disease of older persons, but can also occur in young adults, because certainly an influence of environmental factors and a change of lifestyle. The aim of our retrospective analysis is to assess and evaluate the extent of the prognostic impact of age on the carcinological prognosis of invasive-muscle-bladder cancer treated by total cystotomy. METHODS: To evaluate the association of patient age with pathological characteristics and recurrence-free and disease survival, we retrospectively reviewed 345 patients with invasive bladder cancer between January 2000 and January 2015...

BACKGROUND: Level I evidence supports the utility of neoadjuvant cisplatin-based chemotherapy (NAC) for muscle invasive bladder cancer (BCa). Since dose dense (ddMVAC) has mostly replaced traditional MVAC, we aimed to compare pathological response and survival rates in patients with locally advanced BCa receiving NAC with ddMVAC versus GC. METHODS: We retrospectively reviewed records of patients with urothelial cancer who received NAC and underwent cystectomy at 20 contributing institutions from 2000-2015...

Purpose Nephrolithiasis is an increasingly common ailment in the United States. Ureteroscopic management has supplanted shockwave lithotripsy as the most common treatment of upper tract stone disease. Ureteral stricture is a rare but serious complication of stone disease and its management. The impact of new technologies and more widespread ureteroscopic management on stricture rates is unknown. We describe our experience in managing strictures incurred following ureteroscopy for upper tract stone disease. Materials and methods Records for patients managed at 4 tertiary care centers between December 2006 and October 2015 with the diagnosis of ureteral stricture following ureteroscopy for upper tract stone disease were retrospectively reviewed...

OBJECTIVE: Prenatal ultrasound (US) screening detects the hydronephrosis (HN)-dilatation of fetal renal collecting system in 1%-5% of all pregnancies. In most children, HN is detected by prenatal US screening between 18-20 gestational week. Pelvi- ureteric junction (PUJ) stenosis is the most common etiological factor of prenatal HN and requires postnatal follow-up. Diuresis renography plays important role in the follow-up by complementing morphological information obtained by US with the data about differential renal function (DRF) and drainage...

Glioblastoma 2 (GLI2) is a mediator of Sonic hedgehog signaling pathway that plays an important role in development of the central nervous system and limbs. Heterozygous GLI2 mutations have been associated with postaxial polydactyly, various pituitary dysfunction, and holoprosencephaly-like phenotype. Herein, we report a Japanese boy who presented with isolated growth hormone deficiency with ectopic posterior pituitary, postaxial polydactyly, atrioventricular septal defect, intellectual disability and dysmorphic facial features including mid-facial hypoplasia...

L Shirley, R J Thundyil
Intestinal pseudo-obstruction (IpsO) is defined as presence of clinical features of intestinal obstruction without identifiable mechanical obstructive lesion. IpsO is an uncommon gastrointestinal manifestation of systemic lupus erythematosus (SLE) and is largely under-recognised. There are only over 30 published cases in English literature on SLE-related IpsO. Herein, we report two cases of SLE-related IpsO to illustrate the importance of early recognition to avoid unnecessary surgical intervention, as SLE-related IpsO responds well to systemic high dose corticosteroids...

True metastatic ureteric lesions are exceptionally rare when sourced from any primary tumour. Primary prostatic cancer metastasis to the ureter is understandably even more atypical with very few cases reported in current literature. True intramural ureteric metastatic disease deposited from prostate cancer is an even rarer occurrence. We present a case of a man in his mid-60s with left-sided hydronephrosis in the setting of biochemical recurrence of Gleason 9 prostate cancer. Initially misdiagnosed as obstruction secondary to mass effect from a large trigonal lesion, subsequent investigation revealed solid intramural metastatic deposit of prostate primary tumour in the distal ureter...

BACKGROUND: Accurate and timely diagnosis of acute surgical disease in pregnant patient is challenging. Although magnetic resonance imaging (MRI) is the most accurate modality to diagnose acute appendicitis in pregnant patients, it is often used as a last resort because of high cost and long scan time. We performed this study to analyze differential diagnoses of appendix MRI and to investigate if there are any blood tests that can predict surgical condition in pregnant patients. METHODS: A retrospective, cross-sectional study was conducted on 46 pregnant patients who underwent non-enhanced appendix MRI in suspicion of acute appendicitis from 2010 to 2016...

Craniofacial Microsomia (CFM) also known as Oculo-auriculo-vertebral Spectrum (OAVS) or Goldenhar Syndrome, presents wide phenotypic and etiological heterogeneity. It affects mainly the structures originated from the first and second pharyngeal arches. In addition, other major anomalies may also be found, including congenital heart diseases. In this study, we report a patient with distal deletion in the 22q11.2 region and a phenotype which resembles CFM. The proband is a girl, who presented bilateral preauricular tags, left auditory canal stenosis, - malar hypoplasia, cleft lip and palate, mild asymmetry of soft tissue in face, congenital heart disease, intestinal atresia, annular pancreas and hydronephrosis...

INTRODUCTION: Fetal hydronephrosis (HN) occurs in around 5% of pregnancies and its prognosis depends mainly on the grade of the dilation. We attempted to determine the fate of isolated, unilateral, high-grade HN in children with antenatal diagnosis, emphasizing the risk factors for progression. METHODS: We retrospectively evaluated 424 children (690 kidney units) with antenatal HN in the period between 2010 and 2014. We included only those patients with isolated showed SFU Grade 3 HN in 24 (54%) and SFU Grade 4 HN in 20 (46%)...

Intraluminal pressure elevation can cause degenerative disorders, such as ileus and hydronephrosis, and the threshold is fairly low and constant, 20-30 cm H2O. We previously devised a novel two-chamber culture system subjecting cells cultured on a semipermeable membrane to increased culture medium height (water pressure up to 60 cm H2O). Here, we sought to determine how a continuous pressure load of ~30 cm H2O affects proliferating epithelial cells with special interest in the link with cell morphology. We cultured several different cell lines using the low static pressure-loadable two-chamber system, and examined cell growth, cell cycle, and cell morphology...
