Lower abdominal pain when urinating

When a normal person feels like going to the toilet, if he cannot find the toilet for a moment, he will feel his stomach bloated. At this time, he will only feel the urge to go to the toilet. A normal person will not have other symptoms. However, if you feel pain and distension in the lower abdomen when you urinate, you should consider that it may be related to urinary tract infection, and nephritis cannot be ruled out. Therefore, you need to check first to confirm the diagnosis.

Symptoms of urinary tract infection refer to chronic lower urinary tract infection (also known as labor stranguria), which refers to prolonged or repeated attacks of heat stranguria, accumulation of evil toxins, and deficiency of qi and yin, often caused by fatigue or exogenous infection.

Urinary tract infection can be divided into upper urinary tract infection and lower urinary tract infection. The former is pyelonephritis and the latter is mainly cystitis. Pyelonephritis and cystitis can be divided into acute and chronic types. Depending on the presence or absence of underlying diseases, urinary tract infections can be divided into complicated urinary tract infections and uncomplicated urinary tract infections.

Chronic pyelonephritis is often caused by a complicated urinary tract infection that has not been cured. It is divided into three types according to the underlying cause: ① Chronic pyelonephritis with reflux (reflux nephropathy);

②Chronic pyelonephritis with obstruction (obstructive chronic pyelonephritis); ③Idiopathic chronic pyelonephritis. The first two types are particularly common.

This disease is more common in women of childbearing age, with a male to female ratio of approximately 1:8. Clinical manifestations include the following three groups.

1. Cystitis: commonly referred to as lower urinary tract infection. The main manifestation of cystitis in adult women is urinary tract irritation, i.e. frequent urination, urgency, pain, leukocytosis, occasional hematuria, even macroscopic hematuria, and discomfort in the bladder area. Generally there are no obvious systemic infection symptoms, but a few patients may have low back pain, low fever (generally not exceeding 38°C), and the white blood cell count is often not increased. About 30% of cystitis is self-limiting and can heal itself within 7 to 10 days.

2. Acute pyelonephritis: Manifestations include the following two groups of symptoms: ① Urinary system symptoms: including bladder irritation signs such as frequent urination, urgency, and pain when urinating, low back pain and/or lower abdominal pain; ② Symptoms of systemic infection: such as chills, fever, headache, nausea, vomiting, loss of appetite, etc., often accompanied by increased white blood cell count and increased erythrocyte sedimentation rate. There is generally no hypertension or azotemia.

3. Chronic pyelonephritis: The course of chronic pyelonephritis is very hidden. Clinical manifestations are divided into the following three categories: ① Urinary tract infection manifestations: Only a small number of patients may have intermittent symptomatic pyelonephritis, but the more common manifestations are intermittent asymptomatic bacteriuria, and (or) intermittent lower urinary tract infection symptoms such as urgency and frequency of urination, waist and abdominal discomfort and (or) intermittent low fever. ②Symptoms of chronic interstitial nephritis, such as hypertension, polyuria, increased nocturia, and easy dehydration. ③Related manifestations of chronic kidney disease.

4. Atypical urinary tract infection : ① The main manifestation is systemic acute infection symptoms, while local urinary tract symptoms are not obvious; ② The urinary tract symptoms are not obvious, but the main manifestations are acute abdominal pain and gastrointestinal dysfunction symptoms; ③ The main manifestations are hematuria, mild fever and low back pain; ④ There are no obvious urinary tract symptoms, only back pain or low back pain; ⑤ A few people show renal colic and hematuria; ⑥ There are no clinical symptoms at all, but the urine bacterial quantitative culture shows the colony count ≥105/ml.
