• Sexual activity: Sexual intercourse can introduce bacteria into the urethra.
• Certain types of birth control: Diaphragms and spermicidal agents can increase risk.
• Menopause: Decreased estrogen levels can lead to changes in the urinary tract that make it more susceptible to infection.
• Urinary tract abnormalities: Structural problems or blockages (like kidney stones or an enlarged prostate) can trap urine, promoting bacterial growth.
• Suppressed immune system: Conditions like diabetes can weaken the body’s defenses.
• Catheter use: People who need catheters to urinate are at higher risk.
• Poor hygiene: Wiping from back to front after a bowel movement can spread bacteria to the urethra.

Symptoms: Symptoms can vary depending on which part of the urinary tract is affected.

• Bladder infection (Cystitis):
  • Strong, persistent urge to urinate
  • A burning sensation when urinating (dysuria)
  • Passing frequent, small amounts of urine
  • Cloudy, strong-smelling urine
  • Pelvic pressure or lower abdominal discomfort
  • Blood in the urine (hematuria)
• Kidney infection (Pyelonephritis – more serious):
  • Fever and chills
  • Nausea and vomiting
  • Upper back and flank pain (pain in the side and back, often just below the ribs)
• Urethra infection (Urethritis):
  • Burning with urination
  • Discharge

Treatment: UTIs are primarily treated with antibiotics. The type and duration of antibiotics depend on the bacteria causing the infection and its severity. Common antibiotics include:

• Nitrofurantoin
• Sulfamethoxazole/trimethoprim (Bactrim)
• Amoxicillin
• Cephalexin
• Fosfomycin
• Ciprofloxacin or Levofloxacin (fluoroquinolones, often reserved for more severe cases due to resistance concerns)

It’s crucial to:

• Complete the full course of antibiotics as prescribed, even if symptoms improve, to ensure the infection is fully eradicated and prevent antibiotic resistance.
• Drink plenty of water to help flush bacteria from the urinary tract.
• Pain relievers (like phenazopyridine) may be prescribed to relieve burning and urgency, but they do not treat the infection.

2. Treatment for Benign Prostatic Hyperplasia (BPH)

Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland, a common condition in aging men. The enlarged prostate can press on the urethra, causing urinary symptoms.

Treatment for BPH aims to reduce symptoms and improve urine flow. Options range from watchful waiting to medication and surgical procedures.

1. Watchful Waiting (Active Surveillance):

   • Recommended for men with mild symptoms that don’t significantly impact their quality of life.
   • Involves regular check-ups to monitor symptom progression.
   • Lifestyle modifications may be suggested:
     • Reducing fluid intake before bed or going out.
     • Limiting caffeine and alcohol.
     • Emptying the bladder completely when urinating.
     • Not holding urine for long periods.
     • Maintaining physical activity.

2. Medications:

   • Alpha-blockers: These drugs relax the muscles in the prostate and bladder neck, making it easier to urinate. They work quickly but don’t shrink the prostate.
     • Examples: Tamsulosin (Flomax), Alfuzosin (Uroxatral), Doxazosin (Cardura), Silodosin (Rapaflo).
   • 5-alpha reductase inhibitors (5-ARIs): These medications shrink the prostate by preventing hormonal changes that cause growth. They may take several months to show effects but can significantly improve symptoms and reduce the need for surgery in the long term.
     • Examples: Finasteride (Proscar), Dutasteride (Avodart).
   • Combination Therapy: Often, a combination of an alpha-blocker and a 5-ARI is more effective than either drug alone for men with larger prostates and more severe symptoms.
   • Phosphodiesterase-5 inhibitors (PDE5-Is): Tadalafil (Cialis) is approved for BPH symptoms and can also treat erectile dysfunction, which often co-occurs with BPH.

3. Minimally Invasive Procedures: These procedures are less invasive than traditional surgery and aim to remove or reduce prostate tissue or widen the urethra.

   • Transurethral Water Vapor Therapy (Rezūm): Uses steam to destroy excess prostate tissue.
   • Prostatic Urethral Lift (UroLift): Uses tiny implants to hold open the urethra, lifting the prostate lobes away.
   • Transurethral Microwave Thermotherapy (TUMT): Uses microwave heat to destroy prostate tissue.
   • Transurethral Needle Ablation (TUNA): Uses radiofrequency energy to burn away prostate tissue.
   • Prostate Artery Embolization (PAE): Blocks blood flow to parts of the prostate to shrink it.

4. Surgical Procedures (for more severe symptoms or when other treatments fail):

   • Transurethral Resection of the Prostate (TURP): The most common surgical procedure, where excess prostate tissue is removed using a resectoscope inserted through the urethra.
   • Laser Surgery: Various laser techniques (e.g., GreenLight laser, Holmium laser enucleation of the prostate – HoLEP) vaporize or cut away prostate tissue.
   • Transurethral Incision of the Prostate (TUIP): Small cuts are made in the prostate and bladder neck to widen the urethra.
   • Open Prostatectomy: In rare cases of very large prostates or complications, the prostate is removed through an incision in the abdomen.

The choice of treatment depends on the severity of symptoms, prostate size, patient’s overall health, and personal preference.

3. Overactive Bladder (OAB)

Overactive bladder (OAB) is a common condition characterized by a sudden, strong urge to urinate that may be difficult to control, often leading to urgency incontinence (involuntary leakage of urine). It can also involve frequent urination during the day and night (nocturia).

Causes: The primary cause of OAB is involuntary contractions of the detrusor muscle (the bladder muscle) even when the bladder contains only a small amount of urine. The exact reason for these contractions is not always known, but several factors can contribute:

• Nerve damage: Conditions affecting the nervous system (e.g., stroke, Parkinson’s disease, multiple sclerosis, spinal cord injury) can disrupt nerve signals between the brain and bladder.
