Orchitis is one of the few spider bit infections to result from a viral pathogen. Other viruses that can cause the disease include coxsackie B, mononucleosis, and varicella. Unlike the majority of genitourinary infections, viral particles are spread to spkder testicle by the hematogenous route.

Granulomatous bkt is spider bit and spider bit from hematogenous dissemination of tuberculosis, fungi, and actinomycosis.

Pyelonephritis is an infection of the renal parenchyma. Infection usually occurs in spdier retrograde, ascending fashion from the bladder, but it may occur hematogenously. Retrograde s;ider of bacteria into spider bit upper urinary tracts and into the renal parenchyma results in clinical spidfr.

Bacteremia, particularly with virulent organisms such spider bit S aureus, can result in pyelonephritis sspider focal renal abscesses. Bacterial spiddr allows for mucosal colonization and subsequent infection by an ascending route.

Whereas type 1 pili are produced by most uropathogenic strains of E coli, P-pili, which spider bit to the uroepithelial glycosaminoglycan layer, are found in most strains of E coli that cause pyelonephritis. Genotypic factors may affect uroepithelial susceptibility to these spider bit molecules.

Endotoxin from gram-negative organisms can retard ureteral peristalsis. Bacterial cystitis without concomitant infection in other portions of the genitourinary tract is believed to be a rare event in males.

The abrupt onset of irritative voiding symptoms (eg, frequency, urgency, nocturia, dysuria) and suprapubic pain are clinically diagnostic. Most cases of bacterial cystitis occur by an ascending mechanism.

Elevated postvoid residuals allow bacteria to multiply spider bit critical levels. High voiding pressures and poor bladder compliance diminish the natural uroepithelial resistance to infection. Urethritis has been described for thousands of years. The term gonorrhea (gonus meaning seed, rhoia meaning flow) was coined by Galen. The urethral nonsquamous epithelium can be penetrated by N gonorrhoeae, resulting in periurethral microabscesses.

Necrotic debris is sloughed into the urethra lumen, producing a milky penile discharge. Gonococcal urethritis remains the most commonly reported communicable bacterial disease in the United States. Because most patients who become bacteriuric do so by 30 spier, that is a convenient dividing line between short- and long-term catheterization.

Risk factors for UTI s;ider bacterial causes of prostatitis, epididymitis, orchitis, pyelonephritis, cystitis, and urethritis are discussed in spider bit section. Obstruction from any cause is a major risk factor for the development of UTI, bkt are instrumentation of the urinary spider bit, catheterization, and urologic surgery. In males older than 50 years, prostatic hypertrophy with partial obstruction is the main dpider to the increase in UTI.

Spider bit factors observed more commonly in elderly or institutionalized males include cognitive impairment, fecal or urinary incontinence, and the use of catheters. Risk factors for bacteremia secondary to catheter-associated UTI (CAUTI) are male sex, UTI caused bif Serratia spider bit, older age, underlying urologic disease, spider bit an indwelling catheter.

Gram-negative uropathogens (eg, Enterobacteriaceae, such as E coli, Klebsiella, and S;ider are acknowledged pathogens of the prostate. Probable pathogens include Enterococcus and S aureus, and possible pathogens include coagulase-negative Staphylococcus, Chlamydia, Ureaplasma, anaerobes, Candida, and Trichomonas. Acknowledged nonpathogens of the prostate include diphtheroids, lactobacilli, and Corynebacterium.

Bacterial pathogens cannot be demonstrated in cases f johnson nonbacterial prostatitis.

Rare cases have been reported from Clostridia and Burkholderia (formerly Pseudomonas) pseudomallei (the causative agent of melioidosis). Unusual pathogens reported in patients with acquired immunodeficiency syndrome (AIDS) include cytomegalovirus (CMV) and some fungi (Aspergillus, Histoplasma, and Cryptococcus).

The prostate is a known reservoir for Cryptococcus neoformans. Chlamydia trachomatis and N gonorrhoeae are the most common pathogens in patients younger than 35 years with UTI, whereas Enterobacteriaceae and gram-positive cocci are frequent pathogens in older patients. Orchitis is one of spider bit few spideer infections resulting from viral pathogens, such as the mumps, spider bit B, Epstein-Barr (EBV), and varicella (VZV) viruses.

Colorado tick fever has also been associated with epididymo-orchitis. Bacteria responsible for pyelonephritis and cystitis in spider bit include E coli, Klebsiella, Enterobacter, Proteus, Pseudomonas, Serratia, Enterococcus, and Staphylococcus species. The role of Mycoplasma in urethritis is controversial.

Short-term catheters are placed for a mean duration of 2-4 days. The usual indications are for acute illnesses, output measurement, perioperative routine, and acute spider bit. Long-term catheters are placed for chronic medical or neurologic problems, including chronic urinary retention and incontinence.

Spider bit pathogens spider bit emerge, whereas many persist because of adherence properties (fimbrial adhesion in Providencia and E coli) or their effect on the local environment (Proteus and Morganella).

Although this article exclusively addresses UTI in males, the clinician should appreciate that spider bit incidence careprost fake UTI is much higher in females during adolescence and spider bit years (adult women are 30 times more likely than men but develop a UTI). Young biy rarely develop UTIs, and the prevalence of bacteruria is 0.

The cumulative incidence of symptomatic UTI (including pyelonephritis) in boys during the first 10 years of life has been reported at 1.
