Hydro-ureteronephrosis was present in three boys (42%) and reflux was present in one patient. Post-void residual volume was 20 ml (mean 55 ml) in all children.[ncbi.nlm.nih.gov]
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.[ncbi.nlm.nih.gov]
We present a case of AUV with a diverticulum which was misdiagnosed at other center as neurogenic bladder resulting in chronic renal failure.[ncbi.nlm.nih.gov]
We present a neonate with an obstructing anterior urethral valve depicted by longitudinal transpenile ultrasound. Voiding images are recommended to identify the obstructing valve tissue.[ncbi.nlm.nih.gov]
We present a case of a 10-month old male child diagnosed with an anterior urethral valve by micturating cystourethrogram.[ncbi.nlm.nih.gov]
Children with poor stream and recurrentinfections should be evaluated carefully and anterior urethral valve or diverticula should be considered in differential diagnosis of obstructive lesions.[ncbi.nlm.nih.gov]
The patient may present with poor urinary stream, recurrentinfections, or with renal failure. Depending on the severity of anatomical obstruction he may present early at birth or later in childhood if obstruction is minimal [1].[jpgmonline.com]
Conclusion Children with poor stream and recurrentinfections should be evaluated carefully for congenital obstructive malformation and anterior urethral valves should be considered in differential diagnosis of obstructive lesions.[medresearch.in]
The male child may present with poor urinary stream, recurrentinfections, or renal failure.[afrjpaedsurg.org]
A 14-year-old boy presented with repeated episodes of leftflankpain along with fever and chills. Physical examination did not reveal any positive findings. Routine urine examination showed a large number of pus cells.[jpgmonline.com]
He occasionally had fever and leftflankpain but no lower urinary tract symptoms or recurrent urinary tract infections. His urine was turbid and foul smelling.[afrjpaedsurg.org]
Case 2 A 6-month-old male with 1 month history of fever and failure to thrive was found to have acute renal failure. His parents reported a dribbling urinary stream. A catheter was placed, and he was started on intravenous antibiotics for a UTI.[nature.com]

In Type III, mild bladdertrabeculation and ureteral ectasia with low-grade VUR are seen in addition to those findings in Type II.[nature.com]
trabeculation / diverticula Treatment and prognosis Antenatal treatment is possible, consisting of vesicoamniotic shunting (allowing urine to exit the bladder via the shunt, bypassing the obstructed urethra).[radiopaedia.org]
Female homolog [ edit ] Vector diagram of posterior urethral obstruction causing severe bilateral hydronephrosis and bladdertrabeculation The female homolog to the male verumontanum from which the valves originate is the hymen.[en.wikipedia.org]
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.[ncbi.nlm.nih.gov]
As an initial treatment, vesicostomy was performed in the patient. Later, the valve was fulgurated using an endoscopic procedure. During the follow-up period the patient presented normal renal function.[banglajol.info]
The present study highlights the clinical approach in identifying the condition and its treatment options, especially for those, presenting with urethral diverticula.[ncbi.nlm.nih.gov]
The treatment of choice for an isolated AUV is endoscopic valve ablation. 8 In the presence of a small diverticulum with adequate spongiosum, transurethral resection is the favored treatment method.[nature.com]
Renal and bladder function can be preserved by early diagnosis and treatment. Therefore, we reviewed the symptoms at the time of diagnosis in reported Japanese cases.[jstage.jst.go.jp]

The long-term prognosis of AUVs is not clear in the literature.[medresearch.in]
Number of Figures: 2 Number of Tables: 2 ISSN: 1015-3837 (Print) eISSN: 1421-9964 (Online) For additional information: Abstract Anterior urethral valves are a rare congenital anomaly associated with distal urethral obstruction, which can result in a poor prognosis[karger.com]
In partial epispadias, prognosis for continence with treatment is good.[merckmanuals.com]
The overall prognosis is most affected by the degree and duration of obstruction. Severe cases with obstructive cystic renal dysplasia, oligohydramnios and pulmonary hypoplasia are often incompatible with life 2.[radiopaedia.org]
Although posterior urethral valves are predominant as a cause of obstructive uropathy in children, anterior urethral valves may also appear as the underlying etiologic factor in end-stage renal disease that results from obstruction.[ncbi.nlm.nih.gov]
The etiology is reviewed and strategies recommended for patients with these rare entities. Copyright 2010. Published by Elsevier Ltd.[ncbi.nlm.nih.gov]
Various proposed etiologic mechanisms include an abortive attempt at urethral duplication, failure of alignment between the proximal and distal urethra, imbalanced tissue growth in the developing urethra resulting in a remnant of excess tissue acting[mirc.luriechildrens.org]

Epidemiology Most common cause of lower urinary tract obstruction in males The incidence is estimated to be between 1:3,000 and 1:8,000 live male births.[unboundmedicine.com]
Epidemiology In the United States, PUV is the most common cause of lower urinary tract obstruction in male neonates; the reported incidence ranges from 1 per 8000 to 1 per 25,000 live births.[emedicine.medscape.com]
Commonly associated pathophysiologic findings in children with PUV include (1) hydroureteronephrosis, (2) dilated bladder with trabeculations and/or diverticulum, and (3) vesicoureteral reflux.[unboundmedicine.com]
Pathophysiology During the early stages of embryogenesis, the most caudal end of the wolffian duct is absorbed into the primitive cloaca at the site of the future verumontanum in the posterior urethra.[emedicine.medscape.com]
Vesicostomy used as an initial treatment rather than transurethral fulguration may prevent potential complications that can occur due to the small size of the neonatal urethra. DOI: Community Based Medical Journal 2013 July: Vol.02 No 02: 71-74[banglajol.info]
Early diagnosis and management of this rare condition is very important to prevent further damage, infection and vesicoureteral reflux.[ruj.uj.edu.pl]
Surgery (usually via endoscopy) is done at time of diagnosis to prevent progressive renal deterioration.[merckmanuals.com]
Your child will be given antibiotics to prevent infection occurring following the catheterisation.[kidney.org.uk]
