Burning During Urination: Common Causes Like UTIs, STIs, and Kidney Stones

Dysuria (painful or burning urination) is a common symptom with several potential causes. The most frequent is a urinary tract infection (UTI).

Common Causes

1. Urinary Tract Infection (UTI)

• Bacteria (usually E. coli) enter urethra → bladder (cystitis) or kidneys (pyelonephritis).
• Symptoms: burning, frequency, urgency, suprapubic pain, cloudy/foul urine, sometimes fever.
• More common in women (shorter urethra).

2. Sexually Transmitted Infections (STIs)

• Chlamydia, gonorrhea, trichomoniasis, herpes, mycoplasma genitalium.
• Often with discharge, but can present as isolated dysuria.

3. Urethritis (Non-STI)

Chemical irritation (soaps, spermicides), trauma (catheter, vigorous sex), or idiopathic.

4. Kidney or Bladder Stones

Stones moving through urinary tract cause irritation, colicky pain, hematuria, and dysuria.

5. Prostatitis (Men)

Prostate inflammation/infection → perineal pain, dysuria, frequency, sometimes fever.

6. Vaginal Infections (Women)

Yeast, bacterial vaginosis — vulvar irritation causes external burning during urination.

7. Medications

Certain drugs (chemotherapy, some antibiotics) can cause bladder irritation.

8. Interstitial Cystitis / Bladder Pain Syndrome

Chronic bladder wall inflammation without infection.

When to See a Doctor

• Symptoms persist >24 hours
• Fever, flank pain, nausea/vomiting (suggests kidney involvement)
• Blood in urine
• Pregnancy
• Diabetes or immunosuppression
• Recurrent episodes (≥3/year)

Diagnosis and Treatment

Urinalysis, urine culture, STI testing guide targeted antibiotics. Phenazopyridine (Pyridium) provides symptomatic relief but does not treat infection.
