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]

Time of presentation depending on the severity of the anatomical obstruction, it may present antenatally, soon after birth or later in childhood. The clinical presentation of anterior urethral valves is similar to that of PUV. [medresearch.in]

[…] common features at presentation. [nature.com]

Conclusions : AUV are uncommon causes of infravesical obstruction in males and its rarity warrants presentation. [worldwidejournals.com]

• Left Flank Pain

  A 14-year-old boy presented with repeated episodes of left flank pain 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 left flank pain but no lower urinary tract symptoms or recurrent urinary tract infections. His urine was turbid and foul smelling. [afrjpaedsurg.org]

• Bladder Trabeculation

  A VCUG demonstrated grade 5 VUR on the right, which failed to clear after bladder emptying, suggesting a UVJ obstruction as a result of the very thickened heavily trabeculated bladder wall. The bladder was very small. [nature.com]

  When only the bladder is clearly abnormal - thick walled and trabeculated, other conditions to be considered include 5 : neurogenic bladder prune-belly syndrome Promoted articles (advertising) [radiopaedia.org]

  Features that suggest posterior urethral valves are bilateral hydronephrosis, a thickened bladder wall with thickened smooth muscle trabeculations, and bladder diverticula. Voiding cystourethrogram (VCUG) is more specific for the diagnosis. [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]

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. [banglajol.info]

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]

Treatment [ edit ] If suspected antenatally, a consultation with a paediatric surgeon/ paediatric urologist maybe indicated to evaluate the risk and consider treatment options. Treatment is by endoscopic valve ablation. [en.wikipedia.org]

The long-term prognosis of AUVs is not clear in the literature. [medresearch.in]

The long-term prognosis is good. No References No Citations No Supplementary Data No Article Media No Metrics [ingentaconnect.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]

In partial epispadias, prognosis for continence with treatment is good. [merckmanuals.com]

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]

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]

Early diagnosis and management of this rare condition is very important to prevent further damage, infection and vesicoureteral reflux. [ruj.uj.edu.pl]

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. [banglajol.info]

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]
