Introduction

Symptoms of urinary tract infection (UTI) associated with urinary catheterization are primarily characterized by urinary irritation signs, accompanied by systemic infection symptoms such as fever and chills. This condition is commonly seen in patients with long-term indwelling catheters or those who do not regularly replace their catheters. After catheter insertion, patients may develop a UTI, clinically presenting with frequent urination, urgency, dysuria, local burning sensation, purulent discharge from the urethral meatus, and cloudy urine.

Urinary tract infection symptoms associated with urinary catheterization are primarily characterized by urinary irritation signs, accompanied by systemic infection symptoms such as fever and chills. These infections commonly occur in patients with long-term indwelling catheters or those who do not regularly replace their catheters, typically due to low resistance leading to bacterial infection.

Patients may develop urinary tract infections after catheter insertion. Clinical manifestations include frequent urination, urgency, dysuria, local burning sensation, purulent discharge from the urethral meatus, and cloudy urine. Additional symptoms may include fever, chills, general fatigue, loss of appetite, nausea, and vomiting. If left untreated, retrograde infection may occur, potentially leading to complications such as pyelonephritis, and patients may experience low back or flank pain.

Early anti-inflammatory treatment is recommended. The bladder can be irrigated with normal saline, and antibiotics should be selected based on urine culture and drug sensitivity results. Catheters should be replaced regularly. Patients are also advised to drink plenty of warm water to increase urine output, thereby promoting resolution of the inflammation.

Is Pudilan considered a cephalosporin drug?

Cephalosporin drugs are Western antibiotic medications, with cephalosporin compounds as their main active ingredients. Their mechanism of action involves directly killing or inhibiting susceptible bacteria, and they are effective only against bacterial infections, such as bacterial pneumonia and urinary tract infections.

Can qi deficiency cause frequent urination?

TCM holds that qi has a retaining and controlling function. When there is qi deficiency, this controlling function becomes weakened, failing to regulate the bladder's transformation process, leading to abnormal urination and frequent urination.
