Urodynamic changes in patients with anterior urethral valves: Before and after endoscopic valve ablation

Potential for recovery in bladder function after removing a urethral obstruction

“…[8][9][10][11] Thus the absolute value of these parameters does not reflect the duration of the obstructive period, only their trend both during obstruction and after de-obstruction does. The compliance is more informative.…”

“…7,8 Also patients with a more mild form of anterior urethral valves seem to have a better long-term prognosis for bladder and kidney function than patients with PUV. 9 However, these studies are based on single end-point measurements of bladder function. At what point exactly during the obstructive period the changes in bladder function and structure become less reversible is not known.…”

Congenital anterior urethral diverticulum presenting as a scrotal mass in a two-year-old child

“…Various proposed hypotheses include a ruptured syringocele, incomplete hypospadias, cystic dilatation of the periurethral glands, developmental defects of corpus spongiosum, incomplete fusion of a segment of the urethral plate, sequestration of an epithelial nest after closure Congenital anterior urethral diverticulum of urethral folds, and the presence of epidermal pockets communicating with the ventral urethral wall. [4][5][6][7][8][9][10] The clinical presentation essentially depends on the child's age and the degree of obstruction. Generally, onethird of cases are diagnosed in the neonatal period and onehalf by two years of age in patients who have never been catheterized urethrally.…”

“…The clinical presentation of CAUD is highly variable, depending on the child's age and the degree of obstruction. [3][4][5][6] Variable treatment choices, i.e., endoscopic or open interventions with variable outcomes, have been previously reported in the literature. 7 This current study reports a case of anterior urethral diverticulum large enough to involve the right inguinoscrotal region and which was erroneously diagnosed as a spermatic cord cyst or hydrocele preoperatively.…”

Anterior urethral valves without diverticulum, a rare cause of infravesical obstruction and vesicoureteral reflux in children: Report of two cases and literature review

“…The diagnosis of AUV is difficult and can be missed; this situation may lead to a spectrum of complications ranging from simple urethral dilatation to bilateral hydroureteronephrosis resulting in end-stage renal disease (ESRD) [3,4]. A well performed radiological investigation is imperative for diagnosis [2,5]. Although much rarer than posterior urethral valves, they follow the same clinical course and an early diagnosis and treatment can prevent renal morbidity in these patients.…”
