    Study Notes

    Kidney Injuries

    • Represent 1-5% of all genitourinary system injuries.

    • Causes:

      • Blunt injuries stem from direct impacts, rib or spinal compression, and twisting forces from acceleration or deceleration.
      • Penetrating injuries include stab wounds or shotgun injuries.

    • Risk Factors include:

      • Less developed lumbar musculature in children or low body weight patients.
      • Hydronephrosis, large kidney cysts, tumors, ectopic kidneys, or horseshoe kidneys.

    • Presentation:

      • General signs: hypotonia, shock, pallid skin, and conjunctivitis.
      • Local urological symptoms: flank pain, skin hematoma, lesions, and hematuria; degree of hematuria does not correlate with injury severity. Urine leakage may occur with penetrating trauma.

    • Diagnosis Methods:

      • American Association for the Surgery of Trauma (AAST) guidelines include checking status before examination.
      • Ultrasound as the primary assessment tool identifies subcapsular hematomas and lacerations without depth detail.
      • CT with Contrast:
        • Early arterial phase for artery injuries.
        • Nephrographic venous phase for parenchymal assessment.
        • Late excretory phase detects collecting system injuries (10 min wait), often excluded.
      • Intravenous Urography used for emergencies pre-CT.
      • Indications for renal imaging include macroscopic, microscopic, and dipstick hematuria.

    • Complications:

      • Early complications include delayed bleeding, urinary extravasation, abscess formation, and renal arteriovenous fistulas.
      • Late complications can lead to decreased renal function and hypertension.

    • Treatment Options:

      • Conservative treatment is effective for 95% of stable cases, involving bed rest, infusions, analgesics, antibiotics, and blood transfusions.
      • Surgical treatment may require transperitoneal access for hematoma evacuation, urinary leak management, bleeding control, renal parenchymal suturing, or partial nephrectomy.

    • Treatment options include surgical interventions such as partial or radical nephrectomy, along with local therapies like embolization, cryosurgery, and high-intensity focused ultrasound.
    • For metastatic cases, treatment approaches involve chemotherapy, radiotherapy, immunotherapy, and targeted therapies.

    Tumours of Bladder

    • Bladder cancer ranks as the 6th most frequent cancer in men and is the 2nd most prevalent urological neoplasm.
    • Transitional Cell Carcinoma accounts for 90% of bladder cancers, alongside squamous cell carcinoma and adenocarcinoma.
    • Major risk factors include being male, smoking, family history, exposure to aniline dyes, arsenic, iron, and aluminum, as well as chronic bladder inflammation and certain drugs.
    • Common symptoms of bladder cancer consist of macroscopic painless hematuria, dysuria, and pyuria.
    • Metastatic spread can occur through lymphatic or haematogenous routes, with advanced cases showing pneumaturia, hydronephrosis, weight loss, anemia, and palpable tumors.
    • Diagnosis is typically through cytology urine tests to detect cancer cells and cystoscopy with biopsy to visualize and sample the bladder lining.
    • Treatment may involve pre-operative chemotherapy, transurethral resection via a resectoscope, intravesical chemotherapy for low-grade tumors, BCG vaccine for high-grade tumors, and radical cystectomy with urine diversion.

    Neoplasm of Penis

    • The predominant type of penile cancer is squamous cell carcinoma, which represents 65% of cases, followed by verrucous carcinoma and papillary carcinoma (15%).
    • Risk factors include phimosis, chronic penile inflammation, human papillomavirus (HPV) infections, smoking, multiple sexual partners, and early first intercourse.
    • Early signs may include thick and painless lesions on the glans penis or foreskin.
    • Advanced neoplasms can lead to ulceration, localized inflammation, and unpleasant odor from the affected area.

      • Urgent need to urinate, nocturia (nighttime urination), increased frequency, and incontinence.
    • Voiding Symptoms:
      • Difficulty starting urination (hesitancy), spraying or weak flow, intermittent urination, and straining.
    • Post Micronutrition:
      • Sensation of incomplete bladder emptying.
    • Rectal Examination:
      • Symmetric and smooth enlargement of the prostate.

    Diagnosis

    • Urinalysis:
      • Tests for infection, glucosuria (indicates diabetes), and proteinuria (suggests kidney disease).
    • Additional tests include a Complete Blood Count and a PSA test, which has limitations in sensitivity.

    Treatment

    • Conservative Options:
      • Alpha 1 adrenergic blockers and 5-alpha reductase inhibitors to manage symptoms.
    • Hormone Therapy:
      • Antimuscarinic drugs targeting M3 receptors in the bladder wall.

    • Symptoms may include haematospermia (blood in semen) and haematuria (blood in urine).

    Diagnosis

    • Advanced Indicators:
      • Hydronephrosis, lymphoedema, bone pain, and fractures could suggest advanced disease.
    • Metastatic Patterns:
      • Commonly metastasizes to pelvis and vertebrae.
    • Rectal Examination:
      • Asymmetry and firmness may indicate malignancy.
    • Imaging:
      • Ultrasound may show hypoechoic areas; X-ray/MRI/CT can reveal lesions in the prostate, lymph nodes, or bones.
    • Laboratory Evaluation:
      • Elevated Prostate Specific Antigen (PSA) is indicative of potential malignancy.

    Treatment

    • Gleason Cancer Staging:
      • Used to assess cancer progression.
    • Surgical Options:
      • Prostatectomy, cryosurgery, and orchidectomy are common surgical treatments.
    • Radiation Therapy:
      • Utilized to target and destroy cancerous cells.

    Acute Scrotum Syndrome

    • Sudden onset of pain, swelling, and inflammation in the scrotum signals a medical emergency.

    Causes

    • Torsion:
      • Can occur in testicular appendages or the testis itself, leading to acute symptoms such as erythema, nausea, and vomiting.
    • Epididymitis:
      • Manifests as acute scrotal pain along with swelling and tenderness.

    Hydrocele and Varicocele

    • Hydrocele:
      • Defined as a fluid-filled sac surrounding the testicle, which can be primary or secondary to trauma or inflammation.
    • Varicocele:
      • Not detailed in the text, typically refers to enlarged veins in the scrotum, often related to infertility and testicular atrophy.

    Benign Prostatic Hyperplasia (BPH)

    • Loss of the cremasteric reflex on the affected side may be observed.
    • Testicular necrosis can occur if the condition is not addressed quickly.

    Diagnosis and Complications

    • Ultrasound is utilized to assess blood flow to the affected testicle.
    • Surgical exploration is often required to confirm diagnosis.
    • Potential complications include hemorrhage, testicular infarction, and infertility.

    Treatment

    • Manual detorsion involves rotating the right testicle counterclockwise to restore normal position.
    • Surgical detorsion is essential, with bilateral orchidopexy mandated to prevent recurrence of torsion events.

    Torsion of Appendages

    • Involves structures like appendix testis, appendix epididymis, vas aberrans, and paradidymum.
    • Most commonly affects males aged 7 to 14 years, contributing to 80% of cases.

    Presentation of Torsion of Appendages

    • Characterized by acute pain in the testes, typically less intense compared to testicular torsion.
    • Pain is localized, often felt at the upper pole of the testes.
    • Can mimic symptoms of epididymitis.
    • Notable clinical finding includes the "Blue Dot Sign," indicating the presence of torsion of appendage.
