Study Notes
Male Genitourinary System Diseases
- Overview: Includes congenital/neoplastic conditions of the penis, disorders of the testis, prostate, urinary bladder neoplasms, and sexually transmitted diseases.
- Penile Lesions:
- Malformations: Hypospadias (urethral opening on ventral side), Epispadias (urethral opening on dorsal side). Can cause urinary tract infections and urinary incontinence.
- Penile Neoplasms: Squamous cell carcinoma is common, often found in uncircumcised men over 40. Associated with HPV infection and precancerous lesions.
- Scrotum, Testis, and Epididymis:
- Scrotum: Inflammatory processes (infections, dermatoses), rare neoplasms (often squamous cell carcinomas); Associated with occupational factors in some cases.
- Disorders of the Testes: Cryptorchidism (undescended testis), which increases risk for testicular cancer. Vascular disturbances include torsion.
- Testicular Neoplasms: Germ cell tumors (most common), non-seminomatous and seminomas. Increased risk in cryptorchid patients.
- Prostate Disorders:
- Inflammatory lesions (prostatitis): Often related to UTI (often E. coli) or chronic pelvic pain.
- Nodular Hyperplasia (BPH): Common condition affecting older men, related to hormonal stimulation, where enlarged prostate compresses the urethra leading to urinary obstruction.
- Carcinoma: Adenocarcinoma, is the most common prostate cancer in men over 50. Can metastasize to lymph nodes and bone. Screening often involves digital rectal examination and PSA (prostate-specific antigen) testing. Elevated PSA can indicate problems but doesn't guarantee cancer in all cases. Treatment varies, often including surgery, radiation therapy, and hormonal therapies based on the stage of disease.
Disorders of the Urinary Bladder
- Bladder Cancer: Predominantly urothelial carcinoma, occurring frequently in men aged 50 to 80. Characterized by painless hematuria (blood in urine), related risk factors include smoking, prior chronic bladder infections, and exposure to carcinogens. Diagnosis often includes imaging and cystoscopy.
- Urothelial Carcinoma: Treatment options include transurethral resection, immunotherapy, and radical cystectomy. Treatment and prognosis depend heavily on the stage and grade of the tumor.
Sexually Transmitted Infections
- Syphilis: Caused by Treponema pallidum, transmitted via direct contact with cutaneous or mucosal lesions. Three stages (primary, secondary, tertiary) with distinct symptoms. Can lead to serious complications if left untreated. Congenital syphilis can result from transmission during pregnancy, causing various defects in newborns.
