Which infection presents with abdominal pain, hematuria, painful or frequent urination, fever, nausea, and vomiting?

• A. Urinary Tract infection
• B. Kidney stones
• C. Gastroenteritis
• D. Pelvic inflammatory disease

Answer: (A)

Abdominal discomfort with hematuria and urinary symptoms together points to an infection of the urinary tract. When bacteria irritate the lining of the bladder or urinary tract, you get dysuria (painful urination), along with frequency or urgency to void. The bladder and urinary tract irritation can also cause abdominal or suprapubic pain, and blood in the urine is a common finding from the inflammation. Fever suggests the infection may involve the kidneys or be more systemic, which is why nausea and vomiting can occur in this setting.

Kidney stones can cause hematuria and nausea/vomiting, and they may cause urinary discomfort, but the pain is typically intense, colicky, and localized to the flank or groin rather than a more generalized abdominal pain with dysuria. Fever is not a defining feature unless an infection is present.

Gastroenteritis centers on digestive symptoms like vomiting and abdominal cramps, usually with diarrhea, and does not typically include hematuria or urinary burning.

Pelvic inflammatory disease involves lower abdominal pain often with vaginal discharge and cervical motion tenderness, not primarily urinary symptoms with hematuria.

So the symptom cluster most consistent with an infection of the urinary tract.
