Amyloidosis is a protein folding disorder characterized by the deposition of fibrillar proteins into solid organs or tissues. Primary localized amyloidosis of the bladder is very rare and can mimic bladder cancer in its presentation with hematuria, lower urinary tract symptoms or a mass on imaging. A case of localized amyloidosis of the bladder in a 48-year-old man with painless gross hematuria and evidence of bladder mass on ultrasound is presented. Amyloidosis is a rare but important non-malignant process of the bladder...

Ana Licina
Extraperitoneal bladder perforation is a known complication of a commonly performed rigid cystoscopy. If unrecognized, this complication can lead to continuous intra-abdominal fluid leakage with consequent organ function impairment and symptoms. This is the first case report in literature of a transurethral bladder perforation causing an acute abdominal compartment syndrome, which was subsequently managed conservatively with supportive management only. Case Presentation. We describe a clinical course of a 73-year-old Caucasian female whose initial acute presentation involved urinary symptoms...

REVIEW
Michaella Maloney Prasad, Earl Y Cheng
The work-up of a febrile urinary tract infection is generally performed to detect vesicoureteral reflux (VUR) and its possible complications. The imaging modalities most commonly used for this purpose are renal-bladder ultrasound, voiding cystourethrogram and dimercapto-succinic acid scan. These studies each contribute valuable information, but carry individual benefits and limitations that may impact their efficacy. Biochemical markers are not commonly used in pediatric urology to diagnose or differentiate high-risk disease, but this is the emerging frontier, which will hopefully change our approach to VUR in the future...

OBJECTIVE: As life expectancy increases, the number of women reporting adverse genito-urinary symptoms (genitourinary syndrome of menopause; GSM) from menopause, including vaginal dryness and sexual pain, also will increase. Current objective measurements of vaginal atrophy such as maturation index require vaginal swabs and are invasive; at present, no minimally invasive measurements exist. The purpose of this study was to assess whether total vaginal wall thickness (TVT) and total vaginal mucosa thickness (TMT) as measured by transabdominal ultrasound could qualify as additional objective markers of vaginal wall thinning which could be related to menopausal status...

BACKGROUND: Renal and bladder ultrasound (RBUS) is recommended in evaluation of children after an initial, febrile urinary tract infection. Although it is not uncommon to observe debris within the bladder lumen on sonography, the significance of this finding is uncertain. Debris may be interpreted as an indication of ongoing infection, but there have been no studies to date investigating the association of bladder debris with a positive culture. OBJECTIVE: The aim of this study was to evaluate the association of bladder debris noted at the time of RBUS with positive urine culture results obtained from a catheterized specimen, among patients undergoing RBUS and voiding cystourethrogram (VCUG) on the same day...

INTRODUCTION: Complete primary repair of bladder exstrophy (CPRE) is widely used for classic bladder exstrophy (CBE) closure. Long-term renal function with or without dilation in these patients is poorly characterized and may be impacted by bladder storage parameters or recurrent urinary tract infections (UTIs). OBJECTIVE: We sought to assess our long-term experience with CPRE and investigate factors that may influence upper-tract deterioration. STUDY DESIGN: A retrospective review of patients at our institution with CBE undergoing CPRE from 1990 to 2015 was performed...

INTRODUCTION AND OBJECTIVE: Prostatic urethral lift (PUL) is gaining popularity for the treatment of symptomatic benign prostatic hyperplasia (BPH). We describe the feasibility and considerations of performing holmium laser enucleation of the prostate (HoLEP) as a salvage therapy after previous PUL. METHODS: Men who have undergone HoLEP after PUL were retrospectively identified from three institutions with surgeons experienced in HoLEP. Subjects were characterized by age, time from PUL procedure (months) to HoLEP surgery, indication for retreatment, and pre-operative prostate volume by ultrasound...

OBJECTIVES: Fetal lower urinary tract obstruction (LUTO), most often associated with presence of posterior urethral valves, poses high risk of perinatal mortality or postnatal renal failure. Looking for a method of causative treatment we have devel-oped a technique of fetal urethroplasty with a coronary angioplasty balloon catheter inserted under an ultrasonographic guidance via an 18-gauge needle introduced transabdominally to fetal bladder. MATERIAL AND METHODS: We have used this procedure in three women with singleton pregnancies (two primiparas and one multipara, 32-35 years of age), diagnosed with fetal megacystis at 12-16 weeks of gestation...

BACKGROUND: Prune Belly Syndrome (PBS) is a rare entity, usually found in male neonates. It comprises complex urinary tract anomalies, bilateral undescended testis and absence of anterior abdominal wall muscles. Patients with unilateral abdominal wall deficiency, unilateral undescended testis and female neonates with abdominal wall laxity are classified as Pseudo Prune Belly syndrome (PPBS). Reports on PPBS do not highlight the radiological and imaging characteristics of this syndrome and the current literature on the role of newer imaging modalities, such as Magnetic Resonance Imaging (MRI), remains relatively sparse...

INTRODUCTION: Gall bladder Wall Thickening (GWT) is caused by wide spectrum of diseases. Initially Ultrasound (USG) was used as imaging modality for screening of acute abdomen because of its high sensitivity and real time character. Now, Computed Tomography (CT) is used because of its high temporal and spatial resolution. AIM: Evaluation of GWT and its enhancement patterns on contrast enhanced CT scan in a bid to differentiate benign from malignant causes and to correlate the imaging features with clinical and histopathological findings...

Large cell neuroendocrine carcinoma (LCNEC) of the urinary bladder are rare. We present a case of a 72-year-old man who presented with back pain and acute renal failure. Ultrasound showed a soft tissue mass in the base of the bladder causing bilateral ureteric obstruction. Subsequent biopsy of this mass demonstrated neuroendocrine carcinoma. He was commenced on neoadjuvant chemotherapy (carboplatin/etoposide) and proceeded to a radical cysto-prostatectomy. Histology revealed a LCNEC involving the bladder, T4a with invasion through to adipose tissue and posteriorly at perivesical resection margins...

The detection of abnormalities of the fetal urinary system in the first trimester of pregnancy is constantly improving, namely owing to the improved resolution of the image, the use of the endovaginal approach and thanks to sonographers' constant training. The pathological aspects, usually detected in the second trimester of pregnancy, can be suspected early in the first trimester and range from kidneys' cavity dilation to bilateral renal agenesis, polycystic kidney disease, multi-cystic dysplasia and bladder megavessia or bladder exstrophy...

PURPOSE: Advanced radiotherapy techniques have emphasized on the importance of accurate target volume localization and delineation. The aim of this study was to determine time taken to achieve moderate bladder volume under physiological conditions, using transabdominal ultrasound. MATERIALS AND METHODS: Patients with cervical cancer undergoing radical radiation with or without concomitant chemotherapy underwent serial ultrasound to estimate bladder filling. With a strict bladder protocol of consuming 1000 mL of water orally over 30 minutes after emptying the bladder, ultrasound was done after 45 minutes from bladder emptying time and repeated at 15-minute interval till 300 (25) mL filling was achieved and repeated every week...
