Posterior urethral valves: a single center experience over 7 years

Abstract

Early ablation of PUV and detailed attention to bladder management gives a better outcome. With Mohan's valvotome incidence of stricture is less and incidence of residual valves is comparable to endoscopic ablation of PUV.

Posterior urethral valve

“…[17] Urethral stricture Urethral stricture constitutes a signifi cant complication of transurethral approach of valves ablation. [21,40] It occurs in up to 50% of cases and is due to urethral trauma of instrumentation. [1] The availability of miniature endoscope results in a decreased incidence of urethral stricture.…”

“…[21] Delayed post natal presentation is often with specific urological symptoms like voiding disturbance, urine retention and urinary tract infection (UTI). Non-specific symptoms secondary to azotemia or sepsis are not uncommon.…”

“…Mohan's valvotome is invaluable in the developing world where pediatric cystourethroscopes are not readily available. [21,[30][31][32][33] e) Fogarty or Foley's balloon catheter: The baby is anesthetized and a size 6 Fr catheter is introduced transurethrally. The bladder is filled with contrast material or saline until the posterior urethra is filled.…”

Posterior urethra: Anterior urethra ratio in the evaluation of success following PUV ablation

“…Primary valve ablation is the widely accepted treatment modality for newborns with PUV. The incidence of recurrent obstruction following PUV ablation due to residual valve or stricture has been reported to be around 10e20% [3,4]. Some surgeons subject all patients to a routine repeat cystoscopy around 3 months after PUV ablation, while others repeat a VCUG before embarking on a repeat cystoscopy, which warrants a general anesthesia [5e11].…”

“…In addition, respiratory distress at birth due to pulmonary hypoplasia may be the initial sign of urethral obstruction. 9 In infants, poor urinary stream and recurrent urinary tract infection are common.…”
