Introduction
Groin hernias have various sac contents. From vermiform appendix and acute appendicitis to ovaries, fallopian tubes and urinary bladders, hernia contents can greatly differ [1-4]. The term” scrotal cystocele” was first proposed by Levine in 1951 to describe an inguinal-scrotal bladder hernia [5]. Herniation of the urinary bladder is not rare. Literature reports that about 1-3% of all inguinal hernias involve the bladder, more commonly in males over 50 years of age [6]. We are presenting a case with a bladder hernia as a relatively rare entity, its unique presentation, for general awareness in hernia surgery and although non-operative, for its management.
Methods
This is a case report and a review of the literature. This case study was reviewed and approved by IRB. Diagnostic work up and follow up care were carried out at Maricopa Medical Center, in Phoenix, Arizona, USA.
Case Presentation
The patient is a 77 year old man with Parkinson’s dementia, chronic urinary incontinence, aortic stenosis, hypertension and hyperlipidemia who was initially evaluated by an urologist in the emergency department and found to have lower urinary tract symptoms (LUTS), urinary tract infection (UTI) and bilateral hydronephrosis in addition to a right-sided inguinal bladder hernia (IBH) on imaging (see below). Due to presence of bilateral obstructive uropathy secondary to bladder outlet obstruction, a Foley catheter was paced which resolved the bulging scrotal swelling. The UTI was treated with appropriate antibiotics. Following treatment of UTI, the patient was followed in clinic; after a discussion of the risks and benefits of the surgical procedure with the family, the patient was offered non-operative management due to multiple co-morbidities, dementia and functional status. Patient is followed in the clinic every month for management of his Foley catheter. He remains asymptomatic.
Discussion
Most bladder hernias involve the inguinal and femoral canals, with the latter more frequent in women, and a predilection for the right side has been reported [6]. Any portion of the bladder may herniate, from a small portion or a diverticulum to most of the bladder, as observed in our case. Bladder hernias have been classified into three types according to their relationships with the peritoneum: paraperitoneal, the most frequent type, intraperitoneal and extraperitoneal hernia. Anatomically, just like typical groin hernias, inguinal bladder hernias may be classified as indirect or direct, dictated by its relation to the inferior epigastric vessels [6]. Most bladder hernias are asymptomatic and discovered incidentally during surgery or seen on imaging for unrelated reasons. LUTS are most commonly the initial complaints. Patients with large hernias may have specific symptoms, such as decrease in size of the hernia after micturition, or the two-stage micturition, in which the patient initially empties the normally located bladder, then voids again after manual compression of the hernia sac to push urine out [7].
Variety of surgeons repair inguinal hernias. However, in the setting of males over 50, those with recurrent hernias, obese males or males with LUTS, modified approach should be considered - pre-operative imaging and urological consultation - in order to avoid serious iatrogenic bladder injuries. Weather anticipated or discovered during a routine herniorrhaphy, most asymptomatic bladder hernias can be repaired at the same time as the hernia repair via the same incision and without resection. However, there exist instances in which resection is indicated: cancer in the herniated bladder, tight neck of the bladder hernia, true herniated bladder diverticulum or necrosis of the bladder wall [7]. In such cases, multidisciplinary approach, including urologists, general surgeons and radiologists, is recommended for optimal management. At any time that IBH is suspected, anticipation is perhaps the most important factor in minimizing potential injuries. Involving other experts is always advised when uncertainty exists.
