When a scab has formed, try to avoid long baths as this may cause the scab to soften and fall off too early. The wound site may be closed by Dermabond (plastic glue). The Dermabond usually peels off after about a week.[gosh.nhs.uk]
After one year, however, recurrence rates approach 50 to 60 percent and by five years, recurrence falls in the range of 74 to 86 percent (depending on stricture length and degree of spongiofibrosis).[urology.wustl.edu]

Discussion: Posterior urethral valves result in variable degrees of renalimpairment and bladder dysfunction. The anomaly severely affects some boys but is virtually innocuous in others for reasons that remain unclear[3].[jpss.eu]
Such overdistention is exacerbated by polyuria, and can be a cause of secondary hydronephrosis.[nature.com]
Damage to the distal nephron impairs the concentrating ability of the kidney resulting in polyuria and polydipsia (nephrogenic diabetes insipidus), which can worsen bladder function and thereby further risk upper tract function.[pediatricurologybook.com]
Polyuria may be a feature. Acute lower tract obstruction Often follows a history of symptoms of obstruction of bladder outflow (see below). Usually severe suprapubic pain (but not if superimposed on chronic retention or underlying neuropathy).[patient.info]

Key points Transurethral valve ablation is the initial treatment for obstruction caused by PUV, and the vast majority of patients have resolution of hydroureteronephrosis following treatment; however, a small proportion of patients experience persistent[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]
Before treatment, VUR was present in 43% of boys and after EVR, VUR was present in 22%. Post treatment, 19% (0–70%) was reported to suffer from urinary incontinence.[journals.plos.org]
Endoscopic treatment is the best treatment but some newborns may have to wait for this procedure until they have grown.[chw.org]
Posterior urethral valve is found exclusively in males with an incidence of approximately 1 in 5000. [1] In 1919, Young et al. [4] first described PUV, and until the 1960s, it was reported to have an extremely poor prognosis.[archintsurg.org]
