anterior urethral valves

R Babu, S Hariharasudhan, C Ramesh
INTRODUCTION: There are conflicting reports on the criteria with which to determine success following posterior urethral valve (PUV) ablation. The aims of this study were to assess the value of the posterior urethra: anterior urethra ratio (PAR) in predicting successful PUV ablation. MATERIALS AND METHODS: All neonates and infants with confirmed PUV on voiding cystourethrogram (VCUG) were included. Initial PAR was computed by dividing maximum posterior urethral diameter by anterior urethral diameter...

BACKGROUND: Urethral valves are infravesical congenital anomalies, with the posterior urethral valve (PUV) being the most prevalent one. Anterior urethral valve (AUV) is a rare but a well-known congenital anomaly. AUV and diverticula can cause severe obstruction, whose repercussions on the proximal urinary system can be important. Few cases have been described; both separately and in association with urethral diverticulum. The presentation of such a rare but important case led us to a report with highlighting its classic imaging features...

We present a rare association of anterior and posterior urethral valves. A 5 days-old boy was admitted because of clinical presenation of lower urinary tract obstruction. A renal ultrasound and voiding cysto-urethrography revealed obstructive pathology in anterior urethra. On endoscopy an association of anterior and posterior urethral valves was recognized, and the valves were incised. Follow-up demonstrated improvement of preoperative signs. We try to recognize an association of anterior and posterior urethral valves in radiological examinations...

Purpose This study aims to evaluate the endoscopic morphological features of congenital posterior urethral obstructions in boys with refractory daytime urinary incontinence and/or nocturnal enuresis. Patients and Methods A total of 54 consecutive patients underwent endoscopy and were diagnosed with a posterior urethral valve (PUV) (types 1-4). PUV type 1 was classified as severe, moderate, or mild. A transurethral incision (TUI) was mainly performed for anterior wall lesions of the PUV. Voiding cystourethrography and pressure flow studies (PFS) were performed before and 3 to 4 months after TUI...

Posterior urethral valves (PUVs) are the most common cause of infravesical obstruction in children, whereas anterior urethral valves and/or diverticula (AUV/D) are less commonly encountered. Concomitant AUV/D and PUV is believed to be very rare and may be missed on the initial evaluation. In this review, we provide brief information on embryology of AUV/D and PUV to explain the concurrent presence of these anomalies. We also summarize the information on published cases of concomitant AUV/D and PUV in the English literature with a special focus on diagnosis and the importance of both voiding cystourethrography and careful urethrocystoscopy...

OBJECTIVE: To report our 12-year experience with endoscopic management of patients with concomitant anterior and posterior urethral valves. METHODS: We retrospectively reviewed the charts of patients referred to us for management of urethral valves from 2000 to 2012 to find cases with concomitant anterior and posterior valves. The diagnosis of valves was first suspected on voiding cystourethrography and confirmed by urethrocystoscopy. We collected available data on patients' age at diagnosis, clinical presentations, ultrasound and urodynamic findings, and surgical treatments...

INTRODUCTION: Endoscopic management of posterior urethral valves and congenital ureteroceles is the current standard to relieve the obstruction. While the most commonly used techniques involve cystoscopic incision with cold knife or electrosurgery, an alternative is to ablate the obstructive tissue with laser energy. With increasing prenatal diagnoses, there has been an increasing shift in the timing of intervention toward earlier periods. The literature contains only two reports of laser ablation in neonates for these disease entities...

This report outlines the case of a 3-year-old boy whose initial presentation was that of asymptomatic hypertension (lowest recording 148/90), found at preoperative check prior to stage 2-correction surgery for distal hypospadias. Upon diagnosis of true hypertension, an ultrasound of the child's renal tract showed evidence of marked hydronephrosis and calyceal dilatation. On the background of deteriorating renal function (Urea 25.5 and Creatinine 188), a Micturating Cystourethrogram was performed, demonstrating posterior urethral dilatation...

Anterior urethral valve (AUV) associated with posterior urethral valves (PUVs) is an extremely rare congenital urologic anomaly resulting in lower urinary tract obstruction. We present our experience with 2 children with concomitant AUV and PUV as well as a literature review. The clinical presentation of concomitant AUV and PUV is variable. Successful endoscopic management can result in improvement in renal function, reversal of obstructive changes, and improvement or resolution of voiding dysfunction.

Anterior urethral diverticula are rare in children. Anterior urethral valves and associated diverticulum is the commonly discussed pathological entity in children. There is a lack of awareness among clinicians regarding less common presentations of anterior urethral diverticula in children; which can have a diverse involvement of the urinary tract. This report describes two uncommon presentations of anterior urethral diverticula in children, their diagnoses and management. A systematic differential diagnosis and review of anterior urethral diverticula in children is also presented...

PURPOSE: To find patients at high risk of obstructive remnant leaflets after valve ablation among boys with posterior urethral valve (PUV), we evaluated any possible relationship between preoperative findings in our patients and residual obstructive leaflets after valve ablation. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 55 patients with PUV that was treated by the same surgeon between 2008 and 2012. Of these, 37 patients (67.3%) had no obstructive remnant leaflets (group A) and 18 patients (32...

PURPOSE: Anterior urethral valves (AUVs) is an unusual cause of congenital obstruction of the male urethra, being 15-30 times less common than posterior urethral valves (PUVs). It has been suggested that patients with congenital anterior urethral obstruction have a better prognosis than those with PUV, with less hydronephrosis, and a lower incidence of chronic renal insufficiency (5 vs. 30%). The long-term prognosis of AUVs is not clear in the literature. In this report we describe our experience and long-term follow up of patients with anterior urethral valve...

Two unusual cases of anterior urethral valves (AUV) without diverticulae are presented. The first case is a male child born with prenatal diagnosis of bilateral hydronephrosis. On cystoscopy, iris-like diaphragm valves were encountered about 3 mm distal to the skeletal sphincter. In the second case, an 18-month-old male child was investigated for recurrent febrile urinary tract infections and obstructed urinary symptoms. Cystoscopy confirmed the presence of slit-like valves 5 mm distal to the skeletal sphincter...

INTRODUCTION: Congenital anterior urethral valves (AUV) are rare and can occur as an isolated entity or in association with proximal diverticula. Diagnosis may be overlooked and ideal treatment is not standardized when both the valve and diverticulum are simultaneously present. We present our experience of congenital AUV. MATERIAL & METHODS: From January 2007 to June 2012 a retrospective review of the medical records of 7 cases of AUV was performed. RESULTS: Three patients were diagnosed as isolated AUV while four presented with associated diverticula...

We report an infant with antenatally detected bilateral hydroureteronephrosis and a penile cyst who was eventually diagnosed with an anterior urethral diverticulum (AUD), subcoronal hypospadias, and posterior urethral valves (PUV) after birth. To our knowledge, there are no reports where all three anomalies have been found to coexist. As per urethral catheterisation was difficult, cystoscopy-guided catheterisation was performed. On retracting the complete foreskin, a subcoronal hypospadias was identified. The AUD was resected partially, and during a cystoscopy for completion of AUD resection, a dilated anterior urethra was found collapsed, and thin PUV were identified and divided...

PURPOSE: To describe the novel technique of anterior vesical hitch to enhance the efficacy and safety of percutaneous bladder surgery. MATERIALS AND METHODS: The anterior bladder wall is anchored to the anterior abdominal wall with the help of a prolene suture passed slightly lateral to the midline midway between the pubic symphysis and umbilicus. Percutaneous cystolitholapaxy and antegrade posterior urethral valve ablation were performed after anterior vesical hitch in five pediatric male patients...

INTRODUCTION: Mitrofanoff appendicovesicostomy is needed for securing a conduit for clean intermittent catheterization in children with myelomeningocele, posterior urethral valves and non-neuropathic neuropathic bladder. An open technique is widely used; herein we report our initial experience with minimally invasive laparoscopic appendicovesicostomy in children. PATIENTS AND METHODS: During 2007-2011 we operated on 4 male children with a mean age of 6 years (3-9) suffering from posterior urethral valves (1), myelomeningocele (2), and non-neuropathic neuropathic bladder (1)...

Symptomatic prostatic cysts presenting with recurrent urinary tract infections and urinary obstructive disorders in young men may be misdiagnosed as benign prostatic hyperplasia, urethral stenosis or neuropathic bladder. We report a case of a 28 year old young man with obstructive and irritative voiding disorders caused by a prostatic cyst, located in the anterior and left lateral lobe of the prostate gland. The cyst appeared to obstruct the bladder outlet by a "ball-valve" mechanism. The prostatic cyst was incised and marsupialized by transurethral resection...
