Recommendations for the treatment of lower non-catheter-related urinary tract infection (UTI) in men are rarely evidence-based. Their management requires the localization of the site of infection, whether it be the urethra, bladder or prostate, and includes antibiotic therapy and in most cases urological assessment. They are often associated with urinary tract procedures or anatomical or functional abnormalities. Nearly 80 % of male UTIs are caused by Enterobacteriaceae. The prevalence of broad-spectrum beta-lactamase-producing strains (ESBL) and quinolone-resistant strains is increasing...

Urethral stones can become impacted in the posterior urethra, typically presenting with varying degrees of acute urinary retention and lower urinary tract symptoms. These are traditionally treated in the inpatient setting, with external urethrotomy or endoscopic push-back of the calculus into the urinary bladder followed by cystolitholapaxy or cystolithotripsy. However, these methods are invasive, involve general anesthesia, and require radiation. In this report, we describe a simple, minimally invasive, and safe alternative technique to visualize and remove impacted prostatic urethral stones under the real-time guidance of transrectal ultrasonography (TRUS)...

AIM: The mechanisms underlying detection and transmission of sensory signals arising from visceral organs, such as the urethra, are poorly understood. Recently, specialized ACh-expressing cells embedded in the urethral epithelium have been proposed as chemosensory sentinels for detection of bacterial infection. Here we examined the morphology and potential role in sensory signaling of a different class of specialized cells that express serotonin (5-HT), termed paraneurons. METHODS: Urethrae, dorsal root ganglia neurons and spinal cords were isolated from adult female mice and used for immunohistochemistry and calcium imaging...

REVIEW
Amanda S J Chung, Kurt A McCammon
Lower urinary tract symptoms (LUTS) after urethral stricture repair are not uncommon. Urgency has been reported in 40% of men and urge incontinence in 12% of men after anterior urethroplasty. De novo urgency and urge incontinence is seen in 9 and 5% of men, respectively, after urethroplasty. Once a complication of urethroplasty (such as recurrent urethral stricture or diverticulum) has been excluded as a cause, evaluation of LUTS in such patients should focus on differentiating bladder dysfunction (overactive bladder, underactive bladder), from other outlet obstruction (such as benign prostatic obstruction), dysfunctional voiding, or medical causes (such as nocturnal polyuria)...

BACKGROUND: Hypospadias is a common congenital malformation in males, in which the urethral orifice is found on the ventral side of the penis as a result of incomplete fusion of urethral folds. The etiology of hypospadias is poorly understood, and may be multifactorial, including genetic, endocrine and environmental factors. The steroid 5-alpha-reductase type 2 (SRD5A2) gene, which is mainly expressed in the ventral side of the urethra in the process of male genital development, plays an important role in urethral shaping...

INTRODUCTION: Children with neurogenic bladder (NGB) often require a lifetime of clean intermittent catheterization (CIC), typically using uncoated catheters (UCs). Hydrophilic catheters (HCs) have lower friction than UCs with reported less damage to the urethra. The purpose of this study is to compare outcomes between these catheters. METHODS: An investigator-initiated, prospective, randomized clinical trial was conducted to compare HCs versus UCs. Children aged 2-17 years with NGB on CIC were enrolled for 1 year...

Persistent cloaca is a rare presentation wherein the urethra, vagina, and rectum converge into a common channel with a single perineal opening. Fetal hydrometrocolpos can result if fluid accumulates behind an obstruction of this common channel. A 29-year-old woman (G4P1021) was referred at 36 2/7 weeks of gestation for evaluation of a fetal abdominal cystic mass. Detailed ultrasonography and magnetic resonance imaging showed two symmetric cystic masses, bilateral hydronephrosis, and oligohydramnios. Elective cesarean delivery was performed at 37 0/7 weeks; the baby weighed 4043 g with Apgar scores of 5 and 6 at 1 and 5 min...

Cyclophosphamide- (CYP-) induced cystitis in the rat is a well-known model of bladder inflammation that leads to an overactive bladder, a process that appears to involve enhanced nitric oxide (NO) production. We investigated the changes in the number and distribution of interstitial cells (ICs) and in the expression of endothelial NO synthase (eNOS) in the bladder and urethra of rats subjected to either intermediate or chronic CYP treatment. Pronounced hyperplasia and hypertrophy of ICs were evident within the lamina propria and in the muscle layer...

INTRODUCTION AND HYPOTHESIS: Studies have suggested that a posterior vaginal wall prolapse might compress the urethra and mask stress urinary incontinence (SUI), much like an anterior vaginal wall prolapse. A recent study with urethral pressure reflectometry (UPR) has shown that the urethral closure mechanism deteriorates after anterior colporrhaphy; this could explain the occurrence of postoperative de novo SUI. We hypothesized that urethral pressure would also decrease after posterior colporrhaphy...

Great interest has been directed towards the use of first-void urine as a liquid biopsy for high-risk human papillomavirus DNA testing. Despite the high correlations established between urinary and cervical infections, human papillomavirus testing is unable to distinguish between productive and transforming high-risk infections that have the tendency to progress to cervical cancer. Thus far, investigations have been primarily confined to the identification of biomarkers for triage of high-risk human papillomavirus-positive women in cervicovaginal specimens and tissue biopsies...

Urinary incontinence symptoms are highly prevalent among women, have a substantial effect on health-related quality of life and are associated with considerable personal and societal expenditure. Two main types are described: stress urinary incontinence, in which urine leaks in association with physical exertion, and urgency urinary incontinence, in which urine leaks in association with a sudden compelling desire to void. Women who experience both symptoms are considered as having mixed urinary incontinence...

Female stress urinary incontinence and pelvic organ prolapse are prevalent conditions in adult women. Among treatment alternatives, more traditional methods of surgical intervention have been supplanted by synthetic polypropylene mesh kits. However, novel complications with mesh-related exposure, pelvic pain alone or with dyspareunia, and increased incidence of revision surgeries, resulted in 2 FDA warnings on transvaginal mesh use for prolapse repair. This review examines the anatomy of the vagina and urethra, the etiology of pain related to mesh use, and the relevant surgical techniques for management of this complication along with their outcomes...
