What causes pain or burning during urination?

Generally, a burning or stinging sensation during urination may result from concentrated urine, inadequate genital hygiene, urethritis, cystitis, or urethral stones. Patients may choose among general measures, pharmacological treatment, or surgical intervention based on their specific condition. A detailed analysis follows:

1. Concentrated Urine

Insufficient daily fluid intake leads to elevated urine concentration; urinary solutes then irritate the urethral mucosa, causing mild stinging. Drink adequate warm water daily and urinate frequently to dilute urine and minimize mucosal irritation.

2. Inadequate Genital Hygiene

Accumulation of debris and secretions in the genital area promotes bacterial growth; during urination, bacteria rub against the urethral mucosa, triggering stinging. Wash the genital area daily with warm water, keep the area dry, and change undergarments regularly.

3. Urethritis

Infection by pathogenic microorganisms causes inflammation of the urethral mucosa, resulting in mucosal hyperemia and erosion. Urine flow over these damaged areas induces stinging pain. Under medical supervision, antibiotics such as levofloxacin tablets, azithromycin dispersible tablets, or enteric-coated nitrofurantoin tablets may be prescribed. Avoid urine retention during treatment.

4. Cystitis

Inflammatory changes in the bladder mucosa may extend to involve the urethra; bladder contraction during urination pulls on the urethra, exacerbating stinging and often accompanied by urinary frequency. Under medical guidance, medications such as cefdinir dispersible tablets, Sanjin tablets, or Relinqing granules may be used, along with increased fluid intake to flush the urinary tract.

5. Urethral Stones

Small stones lodged within the urethra move during urination, abrading the urethral wall and damaging the mucosa, thereby causing stinging. Under medical supervision, stone-expelling granules, Lysimachia christinae granules, or tamsulosin sustained-release capsules may be prescribed. For larger stones, urethral stone extraction surgery is required.

In daily life, maintain adequate hydration and regular urination, practice proper genital hygiene, avoid urine retention, and seek timely medical evaluation and intervention if persistent urethral stinging occurs, to address underlying urological pathology early.
