Overview and definition

Clinical Manifestations: Lower Urinary Tract Symptoms (LUTS)

The symptoms of cystitis are the direct sensory manifestation of urothelial injury and neurogenic inflammation. When the bladder mucosa is inflamed, C-fiber afferent nerves become sensitized (allodynia), interpreting normal distension as pain.

The Classic Symptom Complex (Acute Uncomplicated Cystitis)

  • Dysuria (Alguria): The hallmark symptom. A burning, stinging, or scalding sensation located at the urethral meatus or deep inside the pelvis during voiding. This results from acidic urine flowing over the hyperemic, edematous, and denuded mucosa of the urethra and bladder neck.
  • Pollakiuria (Frequency): The need to void at abnormally short intervals (often every 15-30 minutes), usually passing small volumes (“teaspoon voiding”). Inflammation reduces the bladder’s functional capacity by lowering the threshold for stretch receptor activation.
  • Urgency: A sudden, compelling, and often uncontrollable desire to void immediately. This is caused by involuntary detrusor contractions triggered by mucosal irritation (sensory urgency).
  • Suprapubic Pain: Visceral nociception manifests as a dull, constant ache, pressure, or heaviness in the hypogastrium (lower abdomen, just above the pubic bone).
  • Gross Hematuria: Visible blood in the urine, ranging from pink-tinged to deep red with clots. It occurs in ~30% of cystitis cases (Hemorrhagic Cystitis) due to the rupture of dilated sub-mucosal capillaries. While frightening to the patient, it does not necessarily correlate with the severity of the infection or renal involvement.
  • Malodorous Urine: Bacterial metabolism (the breakdown of proteins and urea) produces volatile amines and ammonia, which create a foul or pungent odor.
  • Dyspareunia: Pain during or after sexual intercourse due to mechanical irritation of the inflamed bladder base.

Differential Diagnosis of Symptoms

Differential Diagnosis of Symptoms

Not all dysuria is cystitis. It is crucial to distinguish:

  • Vaginitis: Dysuria is often “external” (felt on the skin/labia as the urine hits it) rather than “internal.” Associated with discharge, odor, or itch.
  • Urethritis: Often caused by STIs (Chlamydia, Gonorrhea). Symptoms are more gradual in onset and may be associated with a urethral discharge.
  • Overactive Bladder (OAB): Urgency and frequency without dysuria or bacteria.
  • Bladder Stones: Intermittent pain and stopping of the urinary stream (“stuttering stream”).

Systemic Signs (The "Red Flags")

Uncomplicated cystitis is a localized mucosal infection. The presence of systemic signs suggests the infection has breached the local barrier and ascended to the kidneys (Pyelonephritis) or entered the bloodstream (Urosepsis).

  • High-grade Fever (>38∘C).
  • Rigors (shaking chills).
  • Costovertebral Angle (CVA) Tenderness: Pain in the flank/back when tapped.
  • Nausea, vomiting, and profound malaise.

Atypical Presentations in Special Populations

Atypical Presentations in Special Populations
  • The Elderly: The immune response in older adults is blunted (immunosenescence). They often do not present with fever or dysuria. Instead, the primary symptom of a bladder infection may be Acute Delirium (sudden confusion, agitation, or lethargy), a sudden increase in incontinence, anorexia, or unexplained falls.
  • Pediatric Patients: Young children cannot articulate dysuria. Signs may include irritability, poor feeding, unexplained fever, failure to thrive, or new-onset bedwetting (secondary enuresis) in a child who was previously toilet-trained.
  • Spinal Cord Injury (SCI): Patients with neurogenic bladder may not have sensation below the waist. Infection may manifest as increased muscle spasticity, Autonomic Dysreflexia (a life-threatening spike in blood pressure accompanied by headache and sweating), or simply cloudy, malodorous urine.

Risk Factors and Etiology

Understanding risk factors allows for targeted prevention and stratification.

Anatomical and Biological Susceptibility

Anatomical and Biological Susceptibility
  • Female Anatomy: The short urethra and its proximity to the anal reservoir are the primary reasons women experience UTIs 30-50 times more often than men.
  • Vesicoureteral Reflux (VUR): A congenital disability in the ureterovesical valve allowing urine to wash back up to the kidneys during voiding. This prevents complete bacterial clearance and increases the risk of pyelonephritis.
  • Diverticula: Outpouchings of the bladder wall (urethral or vesical) that trap urine, creating stagnant pools where bacteria multiply.
  • Cystocele: Prolapse of the bladder into the vagina due to pelvic floor weakness, causing “kinking” of the urethra and incomplete emptying.

Behavioral and Sexual Factors

Behavioral and Sexual Factors
  • Sexual Intercourse: The most substantial risk factor in young women. Mechanical friction massages periurethral flora into the urethra (“Honeymoon Cystitis”). The risk correlates directly with the frequency of intercourse.
  • New Sexual Partner: Exposure to a new microbiome alters the perineal flora.
  • Spermicide Use: Nonoxynol-9 (found in spermicides and some condom coatings) is a detergent that kills cells. It is toxic to Lactobacillus, disrupting the vaginal pH and allowing E. coli to overgrow.
  • Delayed Micturition: Habitual holding of urine allows bacterial replication.
  • Hygiene: Wiping back-to-front can introduce enteric flora into the urethra.

Hormonal Status

Hormonal Status
  • Pregnancy: A state of physiological immunosuppression and stasis. High levels of progesterone relax the smooth muscle of the ureters (hydroureter) and the bladder, leading to urinary stasis. The gravid uterus compresses the bladder. This makes pregnant women highly susceptible to pyelonephritis, which can cause preterm labor and low birth weight. Asymptomatic bacteriuria in pregnancy must be treated.
  • Menopause: Estrogen deficiency causes urogenital atrophy. The vaginal epithelium thins, glycogen production drops, and lactobacilli disappear. The vaginal pH rises (>5.0), creating a niche for colonization by enteric pathogens like E. coli.

Comorbidities and Iatrogenic Factors

Comorbidities and Iatrogenic Factors
  • Diabetes Mellitus: A significant risk factor. Hyperglycemia impairs neutrophil chemotaxis and phagocytosis. Glucosuria (sugar in urine) provides a nutrient-rich culture medium. Diabetic cystopathy (autonomic neuropathy) leads to a flaccid bladder with high residual volumes. People with diabetes are prone to severe infections like Emphysematous Cystitis.
  • Urinary Obstruction: Anything that blocks the flow of urine prevents the mechanical washout of bacteria. This includes Kidney Stones, Urethral Strictures, and in men, Benign Prostatic Hyperplasia (BPH).
  • Catheterization: The presence of a foreign body bypasses host defenses and provides a surface for biofilm formation. The daily risk of bacteriuria with an indwelling catheter is 3-7%. By day 30, virtually 100% of patients have bacteriuria.
  • Antibiotic Use: Recent use of broad-spectrum antibiotics (such as Amoxicillin for a sore throat) disrupts the native protective flora (vaginal and gut), selecting for resistant organisms and causing subsequent UTIs.

Diagnosis and Staging

A precise urological diagnosis relies on a combination of functional testing, laboratory analysis, and advanced imaging. The diagnostic pathway often begins with non-invasive tests to screen for abnormalities, followed by more invasive procedures if necessary to visualize the urinary tract’s internal structures.

The Physical Examination

The assessment begins with a physical exam. For men, this typically includes a Digital Rectal Examination (DRE) to assess the size, texture, and consistency of the prostate gland. For women with incontinence, a pelvic exam helps assess for pelvic organ prolapse.

Laboratory Analysis

  • Urinalysis: The fundamental test of urology. It checks for red blood cells (indicating bleeding), white blood cells (indicating infection), protein (indicating kidney disease), and glucose.
  • Urine Culture: If infection is suspected, a culture identifies the specific bacteria causing it and determines which antibiotics will be effective.
  • PSA Test (Prostate-Specific Antigen): A blood test used primarily to screen for prostate cancer in men. While elevated levels can indicate cancer, they can also be caused by benign conditions like BPH or infection.
  • Serum Creatinine and eGFR: Blood tests that measure how well the kidneys are filtering waste from the blood.

Functional Testing: Urodynamics

To understand how the bladder and urethra are functioning, urologists use urodynamic testing.

  • Uroflowmetry: The patient urinates into a special funnel that measures the speed and volume of urine flow. A weak stream may indicate an obstruction (such as an enlarged prostate).
  • Cystometry: This measures how much the bladder can hold and the pressure inside it as it fills. It helps differentiate between obstruction and nerve problems.

Advanced Imaging

  • Ultrasound: Often the first-line imaging modality. It uses sound waves to visualize the kidneys (for stones or hydronephrosis), the bladder (for residual urine), and the prostate/testicles.
  • CT Urography: The gold standard for evaluating blood in the urine or kidney stones. It provides detailed cross-sectional images of the entire urinary tract.
  • Multiparametric MRI (mpMRI): A specialized MRI of the prostate used to detect suspicious areas that may be cancer, guiding targeted biopsies.

Endoscopy and Biopsy

  • Cystoscopy: A procedure where a thin, lighted tube (cystoscope) is inserted through the urethra to visually inspect the lining of the bladder and urethra. It is essential for diagnosing bladder cancer and strictures.
  • Prostate Biopsy: If a PSA test or DRE is abnormal, a biopsy is performed. Using ultrasound guidance (often combined with MRI), small tissue samples are taken from the prostate to detect cancer cells.

Treatment Details

Urological treatments have evolved significantly, moving away from large open surgeries toward minimally invasive and robotic techniques. The goal is to treat the condition effectively while preserving organ function (such as continence and potency) and minimizing recovery time.

Medical and Conservative Management

Many urological conditions are managed without surgery.

  • Pharmacotherapy:
    • Antibiotics are the standard for treating UTIs and prostatitis.
    • Alpha-blockers relax the muscles of the prostate and bladder neck to improve urine flow in men with BPH.
    • 5-Alpha Reductase Inhibitors shrink the prostate gland over time.
    • Anticholinergics relax the bladder muscle to treat overactive bladder and urge incontinence.
  • Active Surveillance: For small, slow-growing prostate cancers or small kidney stones that are not causing symptoms, doctors may recommend close monitoring rather than immediate treatment.

Stone Management: Breaking the Blockage

  • Extracorporeal Shock Wave Lithotripsy (ESWL): A non-invasive procedure that uses sound waves to break kidney stones into small pieces that can be passed in the urine.
  • Ureteroscopy: A thin scope is passed up the ureter to the stone. A laser is then used to fragment the stone, and the pieces are removed with a basket.
  • Percutaneous Nephrolithotomy (PCNL): For very large kidney stones, a small incision is made in the back to create a tunnel directly into the kidney, allowing instruments to break up and remove the stone.

Management of Enlarged Prostate (BPH)

  • TURP (Transurethral Resection of the Prostate): The traditional “gold standard” surgery where a heated wire loop is used to cut away excess prostate tissue.
  • Laser Therapy (Greenlight, HoLEP): High-energy lasers are used to vaporize or remove prostate tissue with less bleeding than traditional TURP.
  • Minimally Invasive Therapies: Newer techniques like water vapor therapy (Rezum) or prostatic urethral lift (UroLift) offer symptom relief with minimal side effects on sexual function.

Robotic and Oncological Surgery

Urology is a pioneer in robotic surgery.

  • Robotic-Assisted Radical Prostatectomy: The removal of the entire prostate gland for cancer using the da Vinci robotic system. This allows for high precision, helping to spare the nerves responsible for erections and bladder control.
  • Partial Nephrectomy: Removing only the tumor from the kidney while sparing the healthy kidney tissue.
  • Radical Cystectomy: Removal of the bladder for invasive bladder cancer. Surgeons then create a new way for urine to leave the body, such as a “neobladder” made from intestine or an ileal conduit.
