Pathology: Today Objectives • Predisposing Factors • Pathologic Types • Staging • Grading • spread Management: • Clinical features • Investigations • treatment
Predisposing factors: • Industrial toxins • Drugs: e.g. Cyclophosphamide
Predisposing factors: • Bilharzial infestation
Pathologic Types: • Transitional cell carcinoma: The commonest • Squmous cell carcinoma: In Egypt 50% . • Adinocarcinoma: bladder extrophy • Undifferentiated tumor: Highly aggressive.
Stages • Tis: Carcinoma in situ • Ta: Nan invasive papillary • T1: Invade subepithelial • T2: Invades muscle • T3: Invades perivesical t. • T4: Invades adjacent org.
Clinical Features: • Hematuria • Irritative symptoms • Necroturia
Investigations • Urine analysis and urine cytology • Ultrasound examination • IVU and CT • Cystoscopy and biopsy
Cystogram DD • Bladder mass • Blood clots • Prostatic enlargement • Fungus ball
CT scan • The primary imaging modality in evaluation of bladder tumor.
MRI • MRI has higher soft-tissue contrast than CT
Treatment of superficial bladder CA • Complete TUR-T and immediate single intravesical instillation chemotherapy • Adjuvant intravesical immunotherapy:BCG • Radical cystectomy for certain cases.
Treatment of invasive tumor Operable:Radical cystectomy and urine diversion
Urine Diversion • Continent: • Orthotopic bladder substitution • Continent reservoir for CIC • Ureterosigmoidostomy • Non Continent: - Uretero- cutaneous diversion - Ileal conduit
Orthotopic Neobladder • depends on the intact urethra and sphincter to carry urine to the urethral meatus. • In case the urethra is involved by cancer, a continent reservoir with self catheterizable stoma.
Ileal orthotopic neobladder Voiding cystourethrogram
Complications • Hyper continence • Stone • Metabolic acidosis
Complications • Ascending infection • Hypercholorimic acidosis • Adenocarcinoma
Complications (1) stomal : • Necrosis • Stenosis • Hernia (2) peristomal: • Fungal dermatitis • Contact dermatitis. • Trauma
Uretero Cutaneous Diversions Rarely done because of complications: • Urine leakage. • Infections. • Stenosis.
Regarding bladder tumors, all are true except: a. 90% are squamous carcinomas b. Painless haematuria is the commonest presentation c. Cigarette smoking is an important etiological factor d. Superficial tumors are often well controlled by TUR
Smoking increases the risk of : • Oro-pharyngeal carcinoma • Lung cancer • Carcinoma of bladder • All of the above
Pathology of schistosomiasis may include • ”Swimmers itch” caused by skin penetration by cercariae • Portal hypertension due to fibrosis • Pre-disposition to bladder cancer • All of the above
