This 28 yrs old male presented to us with dysuria of 3 days duration.
Dear Dr. Mazumdar
Yes sir....ift passing through one hole upto bladder drain urine..
These cases are incomplete duplication ,Usually distal 1-2 cm dorsal urethra ,can be checked by passing a infant feeding tube during OPD examination itself. dorsal urethra may be combined with urethral plate by incising it ventrally and then tubularize the urethral plate.
Thank u sir
In cases of Double urethra, most of the situation, ectopic is of good calibre and orthotopic is narrower.
Urethral duplication has been discussed
earlier as well but not in Uroacademy. I am not entering into the realms of
Urethral Duplication but have decided to skirt around it with anomalies close
to it. However to make a beginning, one will have to understand the famous
Effmann’s classification (1976) based on detailed radiological anatomy as seen
in the patients’ urethrograms and is popular among Urologists and Radiologists.
I am providing this classification as a PDF attachment.
In 2015, Amr AbdelHamid AbouZeid* et al suggested a modified
from the various older Classifications.
This classification depends on the
orientation of the double urethral channels. The double Urethra was first
classified into either sagittal type (one urethra above other) or Collateral
Type (Lying side by side). The Collateral type represents a part of partial or
complete caudal duplication; while in the sagittal type, the dorsal urethral
channel was always the accessory one.
another congenital anomaly which is not discussed usually due to its rarity.
This is ‘Prepubic Sinus’.
Stephens (1983) when discussing ‘Abnormal embryology-cloacal dysgenesis’ gave
the classification for this entity.
described 3 types of dorsal urethral duplication according to the anatomy.
1 is a complete or incomplete tandem channel that runs parallel to the normal
urethra from the glans to the bladder, which joins the urethra or ends blindly.
2 is an epispadiac type of channel from the dorsum of the penis to the bladder
or one that joins the urethra at some point.
3 is a dermoid sinus that simulates an accessory urethra but tracks from the base
of the penis in front of the pelvic urethra and bladder behind the pubic
symphysis to or towards the umbilicus.
area not commonly discussed but observed when performing Cystoscopy is the
presence or absence of Lacuna Magna. Sunil Shenoy et al (2011) published an
article addressing ‘An
Endoscopic Study of the Lacuna Magna and Reappraisal of Its Clinical
Significance’ which is worth understanding by all. I am providing the article
as a PDF attachment for your reading.
I am sure these informations
provided will enhance our overall knowledge
With warm Regards,
