Male Pelvis Pathology Flashcards
How many kinds of prostate and SV cysts
six categories
Parenchymal degenerative cysts
Most common
Hyperplastic nodules in transition zone
Insignigant unless large and causing obstruction
Unilocular or thinly septated
Retention Cysts
Focal
result from duct obstruction
firm and mimic cancerous nodule
surface mostly
Congenital cysts
In or close to midline
related to Wolffian or Mullerian ducts
Usually asymptomatic unless infected/large
Where are congenital abnormalities
Common in and around the seminal vesicle and protstate
Utericle cysts
Dilation of prostatic utricle May be seen with unilateral renal agenesis Always midline (small and contained within the prostate, may be large)
Mullerian duct cysts
Remnants of paramesonephric duct
Mostly midline an extends from midline
If big, can extend above the prostate
Teardrop shaped pointed towards the verumontanum, can have calcifications
Ejaculatory duct cysts
Small
cystic dilatation of ejaculatory ducts from ?obstruction; can also be diverticula of duct; assoc. with infertility; can cause perineal pain in patients
Prostate abscesses
Thick, irregular walls, debris contaning cysts resemble abscess
E-Coli
Predisposing factors: Diabetes, instrumentation, immunodeffcny, aspiration TRUS
Cystic neoplasms
Rare
Cystadenoma
Cystadenocarcinoma
Seminal Vesicle cysts are…
rare
usually solitary, asymptomatic, can aspirate if large, associated with renal anomalies like agenesis and APKD
Exophytic cyst
Exterior
Prostatitis
Chronic pain syndrome
Prostatitis does not mean….
Infection, inflammation or protstatic involvement
Prostatitis is
Leading cause of urologist visits in men <50-years of age
>50 1. BPH; 2. Cancer: 3. Prostatitis
What are classifications of prostatitis
Acute bacterial prostatitis
Chronic bacterial prostatitis
Chronic prostatitis/chronic pelvic pain syndrome
Inflammatory
cute prostatitis
UTI ,epididymitis /orchitis may cause infection of prostate
Main causative agents are
Proteus,Klebsiella species, Escherichia coli,chlamydia and gonorrhea.
PSA will be high(protien produced by prostate)
Acute prostatitis treatment
IV antibiotics
Acute prostatitis clinical
Pt presnets with fever, chills,pelvic pain,difficulty in urination or ejaculation
Foul smell in urine / blood in semen
What are risk factors for acute prostatitis
Surgical intervention like bx , catheterization are risk factors
Acute bacterial prostatitis
least common
Symptoms acute urinary or systemic infection
Infection from gram-negative organisms i.e. E-Coli
Acute bacterial prostatitis sonographically
Edema, enlargement, hyperemia, venous engorgement, hypoechoic peripheral halo, patchy echo changes
Chronic bacterial prostatitis
Uncommon
Usually have bacterial urinary infection and febrile
E-Coli most often
No ultrasound findings
Chronic prostatitis (CP)
Most common form of prostatic inflammation
Difficult to treat
Type A (diag. by leukocytes in prostate secretions, urine, semen) and Type B (no evidence of inflammation)
Type B aka Prostatodynia
Sonographic features of chronic prostatitis
normal, or peripheral hypoechoic areas, calcifications, venous congestion, increased arterial flow, bladder neck thickening, hypoechoic prostatic rim, periurethral hypogenicity
Asymptomatic inflammatory prostatitis
Men with hx genitourinary pain with histological inflammatory changes
Often increased PSA = bx where they identify these inflammatory cells
Granulomatous prostatitis
Idiopathic
often following instrumentation
