rial extended beyond the left side of the bladder corpus
and a contrast enhancement was superposed at the left

CT images demonstrated elonging of the bladder to the
left inguinal canal with contrast-filled lumen; in reconstruction images, this was like a dog ear (Figure 2,3).
Discussion
UBH is a rare pathology that has been reported in 1
to 4 % of cases of inguinal hernias, whereas digestive or
omental hernias are frequently observed [1-6].
The main factor for the herniation mechanism is
bladder outlet obstruction (benign prostate hyperplasia, prostatitis, and urethral stricture). The other factors are obesity (especially in elderly males) and loss of
bladder tonus with weakness of the surrounding supporting structures [1-3]. The unidentified reason for
UBH is much more common in the right side; on the
contrary, our patient’s hernia is left-sided [3].
The clinical presentation of UBH is variable, and
nonspecific symptoms like dysuria, urinary frequency,
urgency, and recurrent urinary tract infection were accompanied by a scrotal mass. The important complaint
casting doubt in an elderly patient with scrotal mass is
two-phased voiding: after a normal spontaneous urination, the patient evacuates the bladder with manual
compression and it is defined as the second phase of
urination [1-5].
In patients suffering from groin swelling with twophase urination, US is preferred as the first-line diagnostic choice; it is cost-effective, easy to access, and
atraumatic - safety is achieved [2]. In bladder inguinoscrotal herniation, a hipoechoic cystic mass from the
bladder through the inguinal canal can be seen. The US
can evaluate a bladder hernia according to its relationship with the inferior epigastric artery (generally direct
as medial to vessel) and bladder outlet obstruction,
such as an enlarged prostate or any subtle sign on IVP
[1,2,4]. Being medial to the inferior epigastric artery,
our patient’s herniation was an extraperitoneal direct
type. In differential diagnosis, US can differentiate the
herniated bladder from cystic scrotal mass as hydrocele, spermatocele, and epididymal cyst [4].
The second radiological investigation in exhibiting
a bladder hernia is IVP and cystography. Both of them

have low-level sensitivity [1,2]. During IVP, the patient
position is supine and contrast material may not fill the
hernia sac because of this position. Post-voiding, prone
or erect radiographies must be obtained [1]. The diagnostic triad-suggested bladder hernia in IVP consists of
a small bladder, incomplete visualization of the bladder
base, and an ipsilateral distal third of ureter displacement to the hernia side [1-3].
Other radiological techniques are cystography and
CT. CT has a radiation disadvantage, but it gives more
detailed information about a hernia than cystography.
Extension of the lesion can be easily revealed by multi-slice CT. This can be important information about
scheduling a surgery technique. For example, a bladder
diverticulum mimics UBH, which is treated with an abdominal approach to resect [4], whereas surgical repair
of bladder herniation is generally done via an inguinal
incision, and resection of an uncomplicated UBH gets
additional risks in the postoperative period [1,4,7].
Conclusion
We have underlined that inguinoscrotal hernia content is rarely vesical. The clinical suspicion is raised if
there is a large groin hernia with double-phase voiding
symptoms. US should be the first radiological investigation, but CT clearly assesses and distinguishes the
bladder from other entities before surgery.
