✦ Posterior Urethral Valve Treatment

Transurethral Valve Ablation

Q: At what age can valve ablation be performed?

Valve ablation can be performed from birth in term neonates; premature or very small babies require initial suprapubic drainage until large enough for urethroscopy.

Q: Will ablation cure all the kidney problems?

Ablation relieves obstruction but cannot reverse existing renal damage; regular nephrology follow-up is essential for long-term renal function monitoring.

Q: Can valves recur after ablation?

True recurrence is rare; if obstruction persists after ablation, residual valve tissue or a urethral stricture from the procedure may be responsible.

What is Transurethral Valve Ablation?

Transurethral Valve Ablation is the primary treatment for posterior urethral valves (PUV) in boys — a congenital obstructive lesion of the male urethra causing bladder outlet obstruction, hydronephrosis, and renal impairment. Using a paediatric resectoscope, the obstructing valve leaflets are ablated at the 5, 7, and 12 o'clock positions under direct vision, eliminating the obstruction. Early ablation prevents ongoing bladder and upper tract damage. The procedure is performed under general or spinal anaesthesia with a hospital stay of Day Care / 1 Day. Success rates reach >90% in appropriately selected patients at experienced centres.

Boys diagnosed with posterior urethral valves causing bladder outlet obstruction, hydronephrosis, recurrent UTIs, or renal impairment — typically neonates or young infants after initial bladder drainage. Patients must be adequately fit for anaesthesia and free from active systemic infection before proceeding.

How the Procedure Works

Scope Insertion

Paediatric resectoscope or urethrotome passed transurethrally under general anaesthesia.

Valve Identification

Posterior urethral valves identified at the verumontanum level.

Valve Ablation

Valve leaflets ablated using cold knife or diathermy at 5, 7, and 12 o'clock positions.

Lumen Confirmation

Adequate lumen confirmed; bladder capacity and wall assessed for secondary changes.

Catheter & Monitoring

Urethral catheter left for 24 hours; renal function and drainage monitored closely post-operatively.

Who Needs This Treatment?

→Eliminates the primary obstruction allowing bladder and upper tract recovery.
→Minimally invasive — performed transurethrally without external incision.
→Early ablation prevents progressive renal damage from ongoing obstruction.
→90%+ success in achieving urethral patency in one procedure.
→Simultaneous bladder assessment allows planning of further management.
→Allows upper tract to decompress and recover after obstruction relief.

"Valve ablation is the cornerstone of PUV management. Relieving obstruction early gives the developing bladder and kidney the best chance of recovery — time lost is renal function lost."
