Lymphomas of prostate are very rare tumors. They are not commonly considered in the clinical and histological differential diagnosis of prostatic enlargement. We report a case of a 49-year-old man who presented to emergency department with several weeks of difficulty in urination, for which he was being treated for benign prostate hyperplasia with no improvement. Computerized tomography scan showed lobulated mass originating from the superior aspect of the prostate with right inguinal lymph node involvement and no distant organ metastatic disease...

INTRODUCTION: Duplication of the upper urinary tract is one of the most common congenital urological anomalies. In patients with critically decreased or lost function of one of the renal segments, heminephrureterectomy is usually the treatment of choice. Until recently, this was an open surgery; in cases of complete removal of the ureter, an additional incision in the iliac region was required. Currently, heminephrureterectomy is increasingly performed laparoscopically. We report the experience in laparoscopic heminephrureterectomy (LHNUE) in 10 clinics in Russia and Belarus...

RELEVANCE: Benign prostatic hyperplasia (BPH) is one of the most common urologic diseases of males. In patients who failed drug therapy of lower urinary tract symptoms (LUTS) caused by BPH, the most important indication for surgery is the presence of infravesical obstruction (IVO). IVO is detected by pressure-flow studies and is characterized by high detrusor pressure with decreased urinary flow rate. The invasiveness and high cost of this investigation has stimulated a search for non-invasive techniques that could reliably characterize the presence of IVO secondary to BPH...

Ultrasonography (US) is frequently the first imaging modality used to examine women with symptoms involving the pelvis. It is widely available and involves no exposure to ionizing radiation. Images can be acquired with a transabdominal, endovaginal, or translabial approach, and the use of video clips and three-dimensional reconstructions can be helpful. US is excellent for assessment of the uterus, ovaries, and adnexa. Occasionally, nongynecologic pelvic diseases arising from the gastrointestinal, genitourinary, and musculoskeletal systems and the pelvic peritoneal and extraperitoneal spaces may be detected and can be a source of diagnostic dilemma...

BACKGROUND AND OBJECTIVES: Amputations of the lower extremity remain a common procedure in a high-risk population. Perioperative morbidity and mortality reach as high as 14.1% in below-knee amputations. We aimed to determine whether regional, or neuraxial, anesthesia, when compared with general anesthesia (GA), would be associated with reduced perioperative morbidity and mortality. METHODS: We queried the American College of Surgeons National Surgical Quality Improvement Program data set...

A variety of conditions exists in adults and children in which functional or anatomical urinary tract obstructions cause bladder fibrosis, which reduces the bladder's ability to store and empty urine. Current surgical procedures include removal of the obstructions to facilitate bladder emptying or prompt prenatal or postnatal spinal closure to prevent further neurogenic damage. Bladder fibrosis may occur, and it can get worse if a flow hindrance persists or deteriorates. Anti-fibrotic therapeutic strategies that target a variety of factors have been developed in animal models, but currently there are no anti-fibrotic therapies available for clinical use...

OBJECTIVE: Bladder outlet obstruction (BOO) in women remains an underdiagnosed condition. Although diagnosed rarely in general urologic practice, its incidence in specialist centers has been reported to be up to 29%. In the present study we evaluated the incidence of female BOO in adult women referred for evaluation of lower urinary tract symptoms or urinary incontinence, assessing its etiology and correlating this with its clinical presentation. METHODS: The present study consisted of a retrospective review of a prospectively acquired videourodynamic database of 1142 consecutive women referred for evaluation of lower urinary tract symptoms (LUTS) or urinary incontinence from March 2007 to December 2012 and diagnosed with BOO...

BACKGROUND: The direct costs associated with menopausal and postmenopausal symptoms (hereafter "menopausal symptoms") may include the costs of physician and emergency department visits, medications, laboratory testing, and the management of side effects. However, much remains unknown about the costs related to menopausal symptoms, including how they compare with the costs of other diseases that are common among menopausal women. OBJECTIVE: To compare the economic burden of menopausal symptoms with other select prevalent chronic conditions among a nationally representative sample of US menopausal women aged 45 to 65 years...

BACKGROUND: Current management for men with lower urinary tract symptoms (LUTS) is a pathway that results in prostate surgery in a significant proportion. While helpful in relieving benign prostatic obstruction (BPO), surgery may be ineffective for men suffering from difficulties not relating to BPO. The UPSTREAM trial started recruitment in October 2014 with the aim of establishing whether a care pathway including urodynamics (a diagnostic tool for BPO and thus an indication of whether surgery is needed) is no worse for men, in terms of symptomatic outcome, than one without (routine care)...

CASE DESCRIPTION A 15-year-old spayed female mixed-breed dog was evaluated for a 7-week history of stranguria, pollakiuria, and intermittent urethral obstruction. CLINICAL FINDINGS On initial evaluation, the patient had persistent stranguria with lack of urine production; after multiple unsuccessful attempts to urinate, a large volume of urine was produced. Prior to voiding the large volume, the urinary bladder was not palpable during examination. Abdominal ultrasonography confirmed caudal displacement of the urinary bladder, and the urethra and trigone could not be located ultrasonographically...

The functions of the lower urinary tract have been investigated for more than a century. Lower urinary tract symptoms, such as incomplete bladder emptying, weak urine stream, daytime urinary frequency, urgency, urge incontinence and nocturia after partial bladder outlet obstruction, is a frequent cause of benign prostatic hyperplasia in aging men. However, the pathophysiological mechanisms have not been fully elucidated. The use of animal models is absolutely imperative for understanding the pathophysiological processes involved in bladder dysfunction...

The broad categories of surgical fetal therapy can be separated into either open surgical techniques or minimally invasive endoscopic/ultrasound-guided techniques that require only puncture of the uterus with single or multiple small ports. Benefits of fetoscopic or ultrasound-guided fetal intervention include decreased uterine irritability, decreased incidence of preterm labor, and avoidance of risks associated with hysterotomy and commitment to cesarean delivery for future pregnancies. Fetal abnormalities potentially amenable to ultrasound-guided drainage techniques include thoracic fluid-filled lesions and lower urinary tract obstruction...

The aim of this study was to investigate the feasibility of performing chromosomal karyotype analysis using cells cultured from fetal bladder puncture liquid (FBPL). Therefore, FBPL was extracted from 9 fetuses under ultrasonographic guidance, including 3 cases with fetal lower urinary tract obstruction (megabladder and oligohydramnios) and 6 cases with multiple malformations. The cells obtained from the FBPL were cultured in vitro for chromosome preparation and karyotype analysis. The cells from these 9 cases were all successfully cultured, and the chromosomal mitotic phases obtained could be used for counting and karyotype analysis...
