Most inguinal hernias do not directly involve the urinary bladder or the ureters, and urinary problems alongside a groin bulge are just as often coincidental, caused by a urinary tract infection, benign prostatic hyperplasia, prostatitis, or a kidney stone. In fewer cases, the connection is mechanical. An inguinal hernia can create enough pressure on nearby structures to cause straining to urinate, and in an uncommon but clinically important scenario called a sliding hernia, part of the bladder wall itself becomes part of the hernia sac. This is known as an inguinal bladder hernia, or when the bulge extends further, an inguinoscrotal hernia with bladder involvement, occurring in roughly 0.5 to 4 percent of all inguinal hernias.
This form of hernia tends to follow a recognizable pattern. It is most common in older men, particularly those with obesity, chronic straining, or bladder outlet obstruction from an enlarged prostate. When bladder involvement is present, men may notice lower urinary tract symptoms, commonly abbreviated LUTS, including urinary frequency, urinary urgency, nocturia, urinary hesitancy, a weak urine stream, incomplete bladder emptying, and post void dribbling.
Diagnosis and When to Seek Care
Evaluation typically begins with a physical examination performed standing and lying down, sometimes paired with a Valsalva maneuver, along with a review of whether the hernia is reducible or non reducible. Basic tests often include urinalysis, urine culture, and serum creatinine if obstruction is suspected, while ultrasound or CT of the abdomen and pelvis can confirm bladder involvement in complicated presentations, with cystography or cystoscopy reserved for unclear cases.
General surgery typically manages inguinal hernia repair, while urology becomes involved when LUTS, retention, hematuria, or suspected bladder involvement is present, since coordinating both specialties ahead of surgery reduces the risk of injury to the bladder or ureter. Left unaddressed, a herniated, kinked bladder can occasionally cause hydronephrosis or an extrinsic defect affecting ureter function, one more reason unexplained urinary symptoms with a groin or scrotal bulge deserve evaluation rather than a wait and see approach.
Certain symptoms warrant same day medical care rather than watchful waiting, including an inability to urinate, severe suprapubic pain, fever, nausea, vomiting, or a tender bulge that will not reduce, since these can signal an incarcerated hernia, a strangulated hernia, or bladder incarceration. Heavy lifting, chronic constipation, and reliance on an unadvised truss can all mask a worsening hernia, which is why home management is discouraged once red flag symptoms appear.
Treatment and What Changes After Repair
For men without red flag symptoms, a period of watchful waiting alongside a scheduled surgical consult is often reasonable. When urinary symptoms stem from bladder involvement in the hernia itself, hernia repair, whether performed through an open repair, laparoscopic repair, or with mesh repair, can meaningfully improve LUTS in selected patients. Urinary symptoms caused by an unrelated issue such as BPH or a urinary tract infection will not resolve from hernia surgery alone and need their own treatment. Urinary problems can also follow hernia repair itself. A large international study of
4,151 patients across 32 countries found that postoperative urinary retention developed in nearly 6 percent of male patients overall and in roughly 1 in 11 men aged 65 or older, most often requiring temporary catheterization. Urinary symptoms tied to an inguinal hernia can therefore arise either from the hernia’s anatomy before surgery or as a recognized, usually short term complication of the repair itself, and knowing which one applies helps set realistic expectations going into surgery.
