Inguinal hernias involving the bladder are exceedingly rare and pose a diagnostic challenge. Identifying bladder involvement within an inguinal hernia is imperative to avoid iatrogenic bladder injuries and subsequent complications. Here we discuss a case of inguinal bladder herniation and bladder visualization using methylene blue dye intraoperatively. We present a case of a 45-year-old male who presented with a six-hour history of dysuria and a painful non-reducible right-sided groin mass that had previously been reducible for 17 years. Computed tomography demonstrated an irreducible indirect inguinal hernia-containing bladder. Open Lichtenstein repair was performed, and intraoperative methylene blue-dyed saline successfully identified the herniated bladder, preventing iatrogenic bladder injury. This case report demonstrates the importance of preoperative imaging and intraoperative visualization for the prevention of complications in a rare occurrence of a strangulated indirect inguinal hernia-containing bladder.

An inguinal bladder hernia (IBH) is an abnormal protrusion of the bladder into the inguinal canal accompanied by a peritoneum sheath that creates the hernia sac. Clinical presentations vary greatly from lower urinary tract symptoms (LUTS) and reduction in scrotal size after voiding to being entirely asymptomatic. Since inguinal bladder hernias are uncommon and often accompanied by varied and nonspecific symptoms, it is challenging to diagnose and rarely included in differentials. Currently, computerized tomography (CT) imaging with contrast or voiding cystourethrography is recommended for diagnosis. There is no consensus on the best treatment for inguinal bladder hernias, with options ranging from laparoscopic repair to catheterization. In this study, we report the case of inguinal bladder hernia in an 86-year-old male presenting with symptoms of recurrent hematuria and two failed voiding trials after a Foley catheter placement from prostatomegaly resulting in bladder diverticula, and IBH. He was treated with prostate artery embolization (PAE) to address LUTS related to benign prostatic hyperplasia (BPH). The resultant decreased prostatic volume resolved his symptoms of IBH, hematuria, and urinary retention.

UNASSIGNED: Inguinal bladder hernia (IBH) accounts for <5 % of inguinal hernias. As to our knowledge, this is the first case report of a rare intraperitoneal IBH in Indonesia.
METHODS: Here we present a case report of a 58-year-old Indonesian male complaining of a groin mass on the right side since 1 year ago, accompanied by lower urinary tract symptoms (LUTS), two-stage micturition, lower abdominal discomfort and pain during urinating and coughing. Ultrasound revealed widened inguinal canal containing peritoneum and \"teardrop\" lesion at the inguinal continuing until the right scrotal. The patient was scheduled for open repair of inguinal hernia (herniorrhaphy) with tension-free mesh. Intraoperative findings include the entire bladder herniation located at intraperitoneal.
UNASSIGNED: Symptoms of IBH include inguinal or scrotal swelling with or without pain, LUTS, two-stage micturition, to various symptoms owing to complications. Pre-operative imaging might help to confirm diagnosis. The definitive treatment of IBH is either reduction or resection of the herniated bladder followed by surgical repair (herniorrhaphy).
CONCLUSIONS: IBH is rare but should be suspected in older males (≥50 years old), individuals with weak abdomino-pelvic musculature, and obesity. Pathologies of the bladder, such as bladder outlet obstruction (BOO), chronically distended bladder, and decreased bladder tone related to benign prostate hyperplasia (BPH) or bladder neck stricture can also increase risk of IBH. Treatment with open repair of inguinal hernia (herniorrhaphy) with tension-free mesh is the most common and preferred surgical approach.

Inguinal bladder hernia is a rare clinical condition, and only a small number of reported cases have been treated by laparoscopic surgery. In the present case, the patient was a 78-year-old man who presented to our emergency department with a chief complaint of right inguinal bulge and pain. CT imaging revealed an incarcerated right inguinal hernia containing the small intestine and a portion of the urinary bladder. We performed manual reduction of the incarcerated intestine, and he was admitted to the surgical ward for follow-up. On the 19th day after discharge, recurrence of incarceration developed, and he was readmitted after manual reduction. A laparoscopic transabdominal preperitoneal repair was performed. After careful reduction of the protruding bladder from the hernial orifice, we repaired the right inguinal hernia with a mesh prosthesis. We experienced a rare case of right indirect inguinal bladder hernia that was treated successfully with laparoscopic repair.
