Computerized Tomography of Prostatic and Periurethral Abscesses: 2 Case Reports

Abstract

We report 2 cases of lower urinary tract abscesses disclosed by contrast-enhanced computerized tomography scanning. In each case computerized tomography disclosed the diagnosis when conventional studies failed to reveal a cause, and treatment failed to relieve the signs and symptoms of urinary tract infection.

Minimal Invasive Therapy of Prostatic Abscess by Transrectal Ultrasound-Guided Perineal Drainage

“…All patients were free of symptoms, such as pain and fever, within 24 h after abscess drainage. In all patients, except the 1 on hemodialysis without urine Discussion Clinical symptoms of prostatic abscess, such as fever, dysuria, urinary retention and perineal pain, are variable and hence diagnosis can be difficult [1,2,6]. Lower uri nary tract obstructive symptoms with unexplained fever prostatitis and differentiation between the two entities is difficult [12][13][14].…”

“…Prostatic abscess is a rare, but severe disease with a mortality rate between 3 and 16% [1][2][3], Since the devel opment of effective antibiotics its frequency is decreasing [1,2], It can be an aggressive lesion within the pelvis and may rupture into the urethra, rectum, perivesical space, perineum or ischiorectal fossa and may cause sepsis [4], Therefore, early detection and adequate treatment is nec essary [5], However, prostatic abscess is a difficult clinical diagnosis due to the lack of pathognomonic symptoms and physical findings [3,5], In the past it was not uncom mon in patients with gonorrhea and urethral stricture [ 1,2], Currently Escherichia coli followed by Staphylococci are the most common bacteria found in prostatic ab scesses [1,6], There are also reports on prostatic abscess owing to anaerobic bacteria, fungal infections such as Histoplasma capsulatum or Candida glabrata or tropicans [2,3,[6][7][8][9]. Recently, prostatic abscesses were described in patients with AIDS [7,8], The pathogenesis involves two mechanisms [1,6].…”

“…Recently, prostatic abscesses were described in patients with AIDS [7,8], The pathogenesis involves two mechanisms [1,6]. The first mechanism occurs in older patients with bladder outlet obstruction where the pros fig.…”

Prostatic Malacoplakia Associated with Prostatic Abscess: Diagnosis and Treatment

“…CT findings include enlargement with welldefined areas of low attenuation after administration of intravenous contrast medium and the presence of septations within the abscess cavity. In addition CT can evaluate other contiguous organs involved in inflammatory disease and their response to therapy [12].…”

“…This was often done reluctantly for fear of initiating bacteremia from a pros tatic source. Today, the diagnosis has been facilitated by the increasing availability of sonographic techniques as well as computed axial tomography [3][4][5][6][7][8].…”
