Male Reproductive System-Fung Flashcards
What are the congenital anomalies of the urinary bladder?
Extrophy
Diverticula
Vesicouretal reflux
What are the metaplastic lesions of the urinary system?
- cystitis cystica et glandularis
- squamos metaplasia
- intestinal metaplasia
- nephrogenic adenoma
What is the grading of urothelial tuors?
- urotheilal papilloma
- urothelial neoplasma of low malignant potential
- papillary urothelial carcinoma, low grade
- papillary urothelial carcinoma, high grade
- urothelial carcinoma in-situ
How do you make spermatozoa?
spermatogonia type A-> mitosis-> spermatogonia type B-> mitosis-> primary spermatocytes-> migrate to adluminal compartment-> 1st meiotic division-> secondary spermatocytes-> 2nd meiotic division-> spermatids-> spermatozoa
What is the opening of the urethra on inferior surface of penis due to failure of the urethral folds to close?
Hypospadias
What is this:
opening of urethra on superior surface of penis, due to abnormal positioning of the genital tubercle
what is it associated with?
Epispadias
bladder exstrophy
What is this:
benign warty growth on genital skin
What is it due to?
Condyloma acuminatum
HPV 6 or 11; characterized by koilocytic change
What is this:
necrotizing granulomatous inflammation of the inguinal lymphatcs and lymph nodes
What is it caused by?
lymphogranuloma venerum
sexually transmitted disease caused by Chlamydia trachomatis
How does lymphogranuloma venerum heal and what may it involve?
fibrosis
perianal involvement may result in rectal stricture
What is this:
malignant proliferative of squamos cells of penile skin
Squamos cell carcinoma
What are the risk factors of squamos cell carcinoma?
- high risk HPV (2/3 cases)
- lack of circumcision (foreskin acts as a nidus for inflammation and irritation if not properly maintained)
What are the precursor in situ lesion in squamos cell carcinoma?
Bowen Disease
Erythroplasia of Queyrat
Bowenoid papulosis
What is this:
in situ carcinoma of penile shaft or scrotum that presents as leukoplakia
Bowen disease
What is this:
in situ carcinoma on the glans that prsents as erythoplakia
Erythroplasia of Queyrat
What is this:
In situ carcinoma that presents as multiple reddish papules
-seen in youner patients (40s) relative to Bowen disease and erythroplasia of Queyrat
DOES NOT PROGRESS TO INVASIVE CARCINOMA
Bowenoid papulosis
what is this:
failure of testicle to descend into the scrotal sac
Cryptorchidism
What is the most common congenital male reproductive abrnomality; seen in 1% of male infants. Most cases resolved spontaneously, otherwise orchiopexy is performed before 2 years of ae.
Cryptorchidism
What are complications of cryptorchidism?
testicular atrophy with infertility and increased risk fo seminoma
What is inflammation of testicles?
What causes this?
Orchitis
-Chlamydia trachomatis (D-k) or Neisseria gonorrhoeae, E. coli and pseudomonas, mumps and autoimmune orchitis
What causes orchitis in young adults?
What will this cause?
Chlamydia trachomatis or Neisseria gonorrhoeae
-increased risk of sterility, but libido is not affected because Leydig cells are spared
What will cause orchitis in older adults and what will this cause?
E. Coli and Pseudomonas
-UTI pathogens spread into the reproductive tract
What will cause orchitis in teenage males? What will this cause?
mumps virus
-increased risk for infertility; testicular
What kind of orchitis is this:
-characterized by granulomas involving the seminiferous tubules
autoimmune orchitis
What is this:
twisting of the psermatic cord; thin-walled veins become obstructed leading to congestions and hemorrhagic infarction
What causes this?
Testicular torsion
-usually due to congenital failure of testes to attach to inner lining of the scrotum (via the processus vaginalis)
