DisclaimerMedicine is an ever-changing science.  We have been witnessing changes in diagnostic and therapeutic modalities and guidelines during last several years. We have used sources believe to be reliable for purpose of this website including AUA guidelines, EAU guidelines, NCCN guidelines, Campbell-Walsh-Wein Urology, UpToDate, Merck Manual, Lexi-Comp, FDA website, and other reputable resources. However, due to possibility of human error or changes in medicine, readers are required to confirm the information provided in this website with other sources. Readers are specially required to read all parts of the product information sheet included in the package of each drug they plan to administer and follow those instructions. Readers are also needed to follow instructions of FDA and other regulatory bodies and their own department in this regard. Authors can cite information provided in our textbooks or they need to cite the original resources. This website serves as a general framework. We and other users would adjust the approach per departments policies and patients situation. Forms can be used by other health care professionals.

Acute Bacterial Prostatitis


Mid-stream urine dipstick: 

To check nitrite and leukocytes 

Mid-stream urine culture

Blood culture 

Total blood count 


If fevers persist for longer than 36 hours to rule out prostatic abscess.




For 2 weeks. Up to 4 weeks in some settings.


Initial route of treatment

Third-generation cephalosporin

Broad-spectrum penicillin


Fluoroquinolone: should not be offered to patients who have a fever after prostate biopsy.


Once fever has subsided. Patients who are not severely ill or vomiting may be treated initially with an oral fluoroquinolone.

Ciprofloxacin 500 mg bid, if bacteria is susceptible

Levofloxacin 500 mg daily, if bacteria is susceptible


Alpha-blockers: if they have LUTS

Straight catheterization: for short period of time

Suprapubic catheter: for long-term bladder drainage

Drainage of prostate abscess:

Percutaneous drainage

Transurethral route: lesions that do not respond to
initial percutaneous drainage or are too large to adequately drain percutaneously

Chronic Bacterial Prostatitis

2 glass test

NAAT: Chlamydia trachomatis or Mycoplasma


Ciprofloxacin or levofloxacin: 4-6 weeks

Azithromycin or doxycycline: For intracellular bacteria 

Metronidazole: For Trichomonas vaginalis 


Suppressive antimicrobials in HIV:

If patient is taking HAART and is still persistently immunocompromised, lifetime suppressive antimicrobials is recommended to lower risk progression to prostatic abscess.


Initial test:

Antigen/antibody combination immunoassay (4th generation):

Detects HIV1 and HIV2 antibodies and p24 antigen

If non reactive, no further testing is needed

Second test:

HIV1/ HIV2 antibody differentiation immunoassay

Antibody immunoassay that differentiates HIV1 and HIV2 antibodies.

It is recommended in patients in whom the initial test was positive.

Third test:

HIV1 NAAT test:

If first test is reactive and second test is non-reactive or indeterminant



NAATs:  on a first-void urine sample

Preferred method for detecting N.gonorrhoeae and C. trachomatis. 

May also be used for Trichomonas vaginalis in persistent cases.

Urethral swab culture:

Perform prior to initiation of treatment in patients with a positive NAAT for gonorrhoea to assess antimicrobial resistance profile. 

HIV and syphilis tests


Treat gonorrhea or chlamydia. Treatment for coinfection with Chlamydia trachomatis with oral doxycycline should be administered when chlamydial infection has not been excluded.

Sexual partners should also be treated maintaining patient confidentiality.

Gonococcal infections: Ceftriaxone 500 mg IM, single dose

Chlamydia  UrethritisDoxycycline 100 mg bid for 7 days.

Trichomonas vaginalis: Metronidazole,2 g p.o., single dose

Acute Infective Epididymitis 

Exclude testicular torsion first.

NAAT- on a first-void urine sample

For N.gonorrhoeae and C. trachomatis. 

Mid-stream urine culture


Acute epididymitis most likely caused by sexually transmitted chlamydia and gonorrhea:

Ceftriaxone 500 mg IM, single dose. Plus

Doxycycline 100 mg PO, bid, for 10 day.

Acute epididymitis most likely caused by sexually-transmitted chlamydia and gonorrhea and enteric organisms 

Ceftriaxone 500  mg IM, single dose. Plus

Levofloxacin 500 mg, PO, once a day for 10 days

Acute epididymitis most likely caused by enteric organisms:

Levofloxacin 500 mg, PO, once a day for 10 days


Signs and symptoms of epididymitis that do not subside within 3 days require re-evaluation of the diagnosis and therapy.

Children younger than 14 years and Men older than 50 years should be evaluated for anatomic problems.

Fournier’s gangrene


Broad-spectrum antibiotics:

Piperacillin-tazobactam plus Vancomycin

Meropenem/ Ertapenem

Cefotaxime plus metronidazole or clindamycin

For dose, refer to common medications page.

Repeated surgical debridement:

Limited debridement of non-viable tissue

Tissues with marginal viability may survive due to collateral blood flow.

Multiple procedures in the operating room are needed.

Wound management options are: 

Gauze dressings

Silver sulfadiazine or topical antibiotic 

Wound vac

Suprapubic diversion:

If there is urethral trauma or extravasation

Colostomy: If there is colonic or rectal perforation.

Genital Ulcer Disease (GUD)

Most genital ulcers in the United States are either herpes

(most common) or syphilis. Chancroid is seen in some parts of US, but granuloma inguinale usually is not. Lymphogranuloma venereum incidence is going up in male having sex with male.


The minimum testing for all cases of GUD should include a viral identification test for HSV and a syphilis serology.

HSV tests:

Nucleic acid amplification tests (NAAT)- superior test

Viral culture

Antigen test: if above tests are not available.

Syphilis tests:

Swab from ulcer:

Dark-field examination 
Direct/indirect fluorescent antibody (DFA/IFA) 

Screening serology:

Non-treponemal tests: RPR, or VDRL


Treponemal-specific enzyme immunoassay (EIA)-more sensitive in primary syphilis 

Confirmatory serology:





Chancroid tests:



Gram stain

Lymphogranuloma Venereum 



Granuloma Inguinale

Biopsy- Identification of dark-staining Donovan bodies


HSV: Refer to common medication section.

Primary, secondary, and early latent syphilis

Benzathine penicillin G 2.4 million units IM, single dose

In case of penicillin allergy: Doxycycline 100 mg PO bid for 14 days


There is currently no approved test for HPV in men.


Direct excision


CO2 laser

Patient-applied treatments


Preteens at age 11 or 12 years

vaccination of others not previously vaccinated aged 13-45 years

Molluscum Contagiosum



No treatment is an option for immunocompetent patients.
