Genitourinary disease Flashcards
what are hypospadias?
abnormal openings along the ventral aspect of the penis can be constricted resulting in INC UT infections
what are epispadias?
less common, abnormal openings along the dorsal aspect of the penis: result in UT obstruction and urinary incontinence
What is the most common penile neoplasm? what % of cancer does it account for in US males? what groups is this cancer prominent in?
what is it associated with?
what does this cancer precede?
Squamous cell carcinoma and its precursors= most common penile neoplasm= account for .4% of cancers in males
Most common in uncircumscribed men over age 40
associated wit HPV 16/18 infection
precedes premalignant lesion, red white plaque
Describe the clinical findings of Squamous cell carcinoma of the penis. Who is this cancer rare amongst? Are metastases common? 5 year survival rate?
Squamous cell carcinoma of the penis clinically is seen with crusted plaque, nodule ulceration and irregular margins less commonly as a papillary mass.
Rare amongst young, circumcised males
does NOT commonly metastasize to distant sites.
5 Year survival localized= 66%,
5 year survival metastasized= 27%
what is the first human cancer associated with occupational (environmental factors) like chimney sweeps
scrotal squamous cell carcinoma - rare neoplasm
what is cryptorchidism? prevalence? what may this disorder be? what may it lead to?
incomplete descent of the testes from the abdomen to the scrotum
cryptorchidism occurs in 1% of 1 year old males
may be uni or bilateral
may lead to Sterility
What does cryptorchidism INC? what tx is used to reduce risk of cancer and sterility in patients with cryptorchidism?
Cryptorchidism leads to 3-5 x INC risk for testicular cancer which is a intratubular germ cell neoplasia that develops within the atrophic tubules
Orchiopexy reduces risk of sterility and cancer
inflammatory lesions of the testes are more common in epididymitis or orchitis?
inflammation of the testes is more common in epipidymitis
inflammatory lesions of the testes are often associated with what? arise from complications of what?
inflammatory lesions of the testes are often associated with STDs and often arise from UTI complications and mumps in adults (20%)
What is a vascular disturbance of the testes that results in twisting of the spermatic cord? what must happen or infarction will occur?
Torsion- must be surgery relieved within 6-8 hours
torsion is a true urologic emergency that results in what? happens when and does what clinically?
torsion results in obstruction of venous drainage resulting in rapid, intense vascular engorgement
torsion occurs in adolescence and results in sudden onset of testicular pain
what is the most common cause of painless testicular enlargement? what is its incidence rate? predominant in who?
Testicular neoplasms occurs in 6:100,000 males with a peak incidence of 15-34 years
Describe the heterogeneous groups of testicular neoplasms
35% arise from germ cells and are malignant
5% arise from sertoli or leydig cells and are generally benign
Germ cell tumors of the tests are divided into what two groups? what INC the risk for testicular cancer and how much? what percent of pts have a history of cryptorchidism?
testicular germ cell cancer = seminomas and non seminomatous tumors
INC frequency in undescended testis w a 3-5 X INC risk
only 10% of pts have history of cryptorchidism
What is the histologic appearance of testicular germ cell cancers?
may be pure, single cell type but often mixed multiple cell types
What are testicular cancers that arise from the epithelium of the seminiferous tubules? what is the common location of this cancer? what is the tx of it? what is a important note about this cancer?
Seminomas= arise from epithelium of seminiferous tubules, indolent, often remain confined to the testis, may eventually spread via lymphatics
respond well to chemotherapy, and radiosensitive.
One of the MOST CURABLE cancers
whats a cancer that has several types and tends to spread early via lymphatics and blood? What are the important tumor markers for this cancer?
Non seminomatous tumor: even small ones may present with extensive metastases to liver and lungs
Tumor markes: A-fetoprotein (AFP) and human chronic gonadotropin (HCG)
what is the prognosis of testicular germ cell tumors: how many new cases per year? deaths per year? % of early stage cured for seminomas?
% cured of nonseminomatous tumor into remission?
what is the one germ cell tumor that has bad prognosis due to less chemosensitivity?
8000 new cases per year, 400 deaths annually
seminomas: 95% cured
non seminomatous tumors: 90% pts have remission
Exception is pure chrolocarcinoma (less than 1% tho)= worse prognosis
what are the important categories of prostate disorders
inflammatory lesions (prostatitis)
nodular hyperplasia
carcinoma
prostatitis caused the prostate to do what? minority of these cases are associated with what and can be what?
prostatitis causes an enlarged tender prostate that is associated sometimes with UTI infection from E coli and can be acute or chronic
