A 20-month-old male miniature dachshund was evaluated for a 10-week history of intermittent stranguria, pollakiuria, haematuria and obstructive urolithiasis. Retrograde urethrocystography revealed a subcutaneous saccular structure in the perineal area connected to the intrapelvic urethra associated with urolithiasis. After excision of the perineal saccular structure, microscopical examination confirmed the presence of transitional epithelium lining the diverticulum, with isolated submucosal smooth muscle bundles...

INTRODUCTION: Urethral duplication is a rare and variable malformation of the urinary tract, with non-univocal and complex management. In addition, different classification schemes have been proposed, but none have considered all the possible variants. OBJECTIVE: To report experience with the management of 20 urethral duplication patients and propose a classification of this anomaly. MATERIALS AND METHODS: A retrospective analysis collecting information regarding 20 patients (Table) with urethral duplication treated at a single institution over the past 40 years...

Disorders of sexual development (DSD) encompass a broad spectrum of urogenital malformations and are amongst the most common congenital birth defects. Although key genetic factors such as the hedgehog (Hh) family have been identified, a unifying postnatally viable model displaying the spectrum of male and female urogenital malformations has not yet been reported. Since human cases are diagnosed and treated at various stages postnatally, equivalent mouse models enabling analysis at similar stages are of significant interest...

Beckwith-Wiedemann Syndrome (BWS) is an overgrowth disorder with various congenital anomalies. Although the most classic constellation includes macrosomia, macroglossia, and omphalocele, nephrourological findings are commonly associated with BWS. Clinical presentation is highly variable because of its complex molecular heterogeneity, which involves changes in DNA methylation and disruption of growth regulatory genes. We report 3 pediatric patients, ages 13 months to 3 years old, who presented with clinical features consistent with BWS...

PURPOSE: To assess the reproducibility of the Valsalva leak point pressure (VLPP) based on urodynamics in females with stress urinary incontinence (SUI). MATERIALS AND METHODS: From October 2008 to December 2009, 65 consecutive women with urodynamically confirmed SUI underwent duplicate VLPP measurements. The intra-individual reproducibility of the VLPP recording obtained by one urologist was determined. The two observations were separated by a 10-min interval. RESULTS: The differences between the repeated measurements were not significant (initial vs...

BACKGROUND: Teaching and learning hypospadias repair is a major component of pediatric urology fellowship training. Educators must transfer skills to fellows, without increasing patient complications. Nevertheless, few studies report results of surgeons during their first years of independent practice. PURPOSE: To review outcomes of distal hypospadias repairs performed during the same 2-year period by consecutive, recently matriculated, surgeons in independent practice, and to compare them to results by their mentor (with >20 years of experience)...

BACKGROUND: Australia introduced a national quadrivalent human papillomavirus (4vHPV) vaccination programme for girls and young women in April, 2007. The HPV genotypes targeted by the female vaccine could also affect the protection afforded to heterosexual men. We examined the prevalence of 4vHPV targeted vaccine genotypes and the nine-valent HPV (9vHPV)-targeted vaccines genotypes among sexually active, predominantly unvaccinated heterosexual men from 2004 to 2015. METHODS: We did a retrospective, observational study of urine and urethral swab specimens from heterosexual men aged 25 years or younger attending the Melbourne Sexual Health Centre between July 1, 2004, and June 30, 2015, who tested positive for Chlamydia trachomatis...

OBJECTIVE: To highlight genetic pattern of posterior urethral valves (PUVs), we performed a genetic study on 2 siblings affected. PUVs are the most common congenital cause of lower urinary tract obstruction and an important cause of renal failure in infants (50% progress to end-stage renal disease in 10 years). PUVs occur in 1 of 5000-8000 male infants, but real incidence is arduous to determine because of the wide spectrum of possible clinical presentation. A different recurrence rate is reported in African Americans and children with Down syndrome, although usually PUVs are not found in syndromic conditions but constitute an isolated disorder...

A 12-year-old boy presented with poor flow and recurrent urinary tract infections following hypospadias repair at the age of 3 years. The evaluation revealed urethral duplication with a hypoplastic dorsal urethra and patent ventral urethra. He also had duplication of the bladder neck, and on voiding cystourethrogram the ventral bladder neck appeared hypoplastic and compressed by the dorsal bladder neck during voiding. The possibility of functional obstruction of the ventral urethra by the occluded dorsal urethra was suspected, and he underwent a successful urethro-urethrostomy...

Female hypospadias is a rare anomaly of the female urethra where it opens on the anterior vaginal wall anywhere between the introitus and the fornix. It is often associated with other genitourinary anomalies such as Cloacal malformation, female pseudohermaphroditism, nonneurogenic neurogenic bladder and urethral duplication. Idiopathic female pseudohermaphroditism is extremely rare, and most cases occur secondary to adrenogenital syndrome or maternal androgen exposure. We report a unique case of a 1-year and 4-month-old girl who presented with ambiguous genitalia and renal failure secondary to a non-neurogenic neurogenic bladder...

Bladder duplication is a rare entity in children. The term encompasses a wide spectrum of anomalies from isolated bladder duplication in coronal or sagittal planes to duplicated bladder exstrophy and associated musculoskeletal and visceral anomalies. Given this wide variability, the treatment of these patients is not standardized. We hereby present a female patient with chief complaint of long-standing urinary incontinence who had complete bladder and urethral duplication and pubic diastasis. The patient was treated with bulking agent injection at the incompetent bladder neck and proximal urethra with resolution of incontinence, obviating the need for extensive surgeries...

Bladder exstrophy is a rare major birth defect which requires specialized surgical care. Associated genitourinary tract anomalies are extremely rare in this population, yet significantly impact surgical planning and outcomes. In this case, a full-term newborn girl with a prenatal diagnosis of classic bladder exstrophy was found to have a complete duplicated left collecting system with an ectopic ureter inserted to urethral plate. The patient underwent modern staged repair of exstrophy with bilateral anterior innominate osteotomies and concomitant ureteral reimplantation-the first reported case of ureteral reimplantation at the time of initial closure in a newborn...

The cause of posterior urethral valves (PUV) is unknown, but genetic factors are suspected given their familial occurrence. We examined cases of isolated PUV to identify novel copy number variants (CNVs). We identified 56 cases of isolated PUV from all live-births in New York State (1998-2005). Samples were genotyped using Illumina HumanOmni2.5 microarrays. Autosomal and sex-linked CNVs were identified using PennCNV and cnvPartition software. CNVs were prioritized for follow-up if they were absent from in-house controls, contained ≥ 10 consecutive probes, were ≥ 20 Kb in size, had ≤ 20% overlap with variants detected in other birth defect phenotypes screened in our lab, and were rare in population reference controls...

INTRODUCTION AND HYPOTHESIS: Scant literature exists about the quality of urogynecological content on social media. Our objective was to measure the accuracy and comprehensiveness of YouTube videos related to mid-urethral sling (MUS) procedures. METHODS: YouTube was searched using the terms "mid-urethral sling," "vaginal tape," "TVT," "TOT," "TVT surgery," and "TOT surgery." Duplicates and videos with less than 1,000 views were excluded. We developed a standardized questionnaire for this project, assessing each video's target audience, main purpose, relevance, informed consent elements, surgical steps, and bias...
