PURPOSE
We report the surgical management and voiding outcome of 8 cases of "Y" duplication of the urethra.
MATERIAL AND METHODS
Of the fifteen cases of urethral duplication seen between 2007 to 2017. We retrospectively reviewed
the prospectively collected records of eight cases who presented with "Y" duplication of urethra
(Type IIA2 as per Effman classification). We document their clinical, radiological and cystourethro-
scopic findings and outcomes. Voiding outcomes were evaluated on the basis of LUTS, UFM, and
PVR.
RESULTS
Mean age at presentation was 4.9 +/- 4.7 years. Seven of them passed urine mainly through the
opening near anal verge and only one through the glanular urethral meatus. In three cases the or-
thotopic channel was managed by PADUA procedure alone and their ventral channel was excised.
Two patients had ventral channel transposition as a perineal urethrostomy and following anterior
urethral PADUA procedures the intervening gap was repaired with a buccal mucosa. In one patient
ventral channel transposition and perineal urethrostomy was combined with a Mitrofanoff channel.
In two cases surgical repair has been deferred until puberty. Five (83 %) of the six patients who
underwent surgical correction are now voiding normally through external urethral meatus at the
penile tip with a median follow up of 3.8 years.
CONCLUSIONS
"Y" type urethral duplication is a complex, rare urethral anomaly requiring individualised manage-
ment and can result in normal voiding. This is one of the largest series documenting the outcomes
of "Y" duplication of the urethra.

PURPOSE
Bladder function in boys born with posterior urethral valves (PUV) is often abnormal. We aimed to
assess the bladder status in PUV babies following valve resection.
