Conservative management of a seminal vesicle abscess

Acute Epididymo-Orchitis Complicated With Abscesses in Testis and Seminal Vesicles: A Case Report

Epididymo-orchitis is a common intra-scrotal inflammation among males that causes swelling of the epididymis and testis. In the era of modern antibiotics, complications associated with this condition are now rare. Herein, we report a 28-year-old man with acute epididymo-orchitis complicated by the formation of several abscesses involving the left testis and seminal vesicles. The literature review showed this patient as the first case with such extensive complications following epididymo-orchitis. Initial antimicrobial therapy was unable to resolve the condition. The management necessitated surgical intervention, which included MRI-guided aspiration of the seminal vesicle abscesses and testicular sparing drainage of the testicular abscess.

Seminal vesicle abscess: A case report and review of the literature

Seminal vesicle abscess (SVA) is a rare pathology. We review the literature and present the case of a 54-year-old presenting with an SVA treated successfully with percutaneous transgluteal drainage and subsequently, transrectal ultrasound (TRUS)-guided transrectal drainage.

Cross-sectional imaging of complicated urinary infections affecting the lower tract and male genital organs

Complicated urinary tract infections (C-UTIs) are those associated with structural or functional genitourinary abnormalities or with conditions that impair the host defence mechanisms, leading to an increased risk of acquiring infection or failing therapy. C-UTIs occur in patients with risk factors such as neurogenic dysfunction, bladder outlet obstruction, obstructive uropathy, bladder catheterisation, urologic instrumentation or indwelling stent, urinary tract post-surgical modifications, chemotherapy- or radiation-induced damage, renal impairment, diabetes and immunodeficiency.

Multidetector CT and MRI allow comprehensive investigation of C-UTIs and systemic infection from an unknown source. Based upon personal experience at a tertiary care hospital focused on the treatment of infectious illnesses, this pictorial essay reviews with examples the clinical features and cross-sectional imaging findings of C-UTIs affecting the lower urinary tract and male genital organs. The disorders presented include acute infectious cystitis, bladder mural abscesses, infections of the prostate and seminal vesicles, acute urethritis and related perineal abscesses, funiculitis, epididymo-orchitis and scrotal abscesses. Emphasis is placed on the possible differential diagnoses of lower C-UTIs.

The aim is to provide radiologists greater familiarity with these potentially severe disorders which frequently require intensive in-hospital antibiotic therapy, percutaneous drainage or surgery.

Teaching Points

• Complicated urinary tract infections occur in patients with structural or functional risk factors.

• CT and MRI comprehensively investigate complicated urinary infections and sepsis from unknown sources.

• Infections of the urinary bladder, prostate, seminal vesicles, urethra and scrotum are presented.

• Emphasis is placed on differential diagnoses of complicated lower urogenital infections.

• Unsuspected urinary infections may be detected on CT performed for other clinical reasons.

Seminal vesicle cyst forming an abscess and fistula with the rectum review of perianal drainage and treatment

The clinical presentation and treatment modalities of seminal vesical abscesses are not well documented. The first case of a seminal vesicle cyst which formed an abscess after transrectal aspiration with subsequent formation of a fistula with the rectum is reported herein. The abscess was drained perianally, an approach that has not previously been reported. A brief comparison of the reported treatment modalities is also provided.

Absceso Primario de vesícula seminal: Diagnóstico y tratamiento mediante ecografía transrectal

A 38 years old man with the only past medical history of bilateral orchiopexy 15 years ago is diagnosed of left primary seminal vesicle abscess. The patient is sent to our emergency service with an ultrasound finding of either dilated vas deferent or seminal vesicle abscess with hiperecogenic material inside it. The examination was performed after a 5 month history of purulent ejaculation. The diagnose of seminal vesicle abscess is confirmed by TRUS and, in the same procedure, drainage of the abscess was completed by needle-aspiration puncture. After this treatment the patient stay 12 hours at the observation room with intravenous antibiotics and is discharged home with oral antibiotics. We are interested in this case because of the low incidence of this pathology and the easy diagnosis and treatment by TRUS.

Transrectal ultrasound-guided transperineal and transrectal management of seminal vesicle abscesses

OBJECTIVE

The treatment of seminal vesicle abscesses (SVA) by transrectal ultrasound-guided transrectal and transperineal approaches were evaluated in this study.

MATERIALS AND METHODS

Six SVA cases were diagnosed among 2350 patients admitted to our ultrasound unit with prostate and seminal vesicle symptoms during the last 6 years. Four out of six cases had bilateral, and two had unilateral SVA. Transperineal puncture and aspiration was done in four patients with bilateral abscesses and transrectal approach was preferred in two patients with unilateral abscesses.

RESULTS

For both approaches, the aspiration was successfully done without any complication. The mean durations of intervention were 64 and 13 min, and the durations of hospitalization were 2 and 3 days for the transperineal and transrectal approaches, respectively.

CONCLUSION

Transrectal ultrasound examination allows simultaneous evaluation of the gland and the guidance for a needle puncture and aspiration. Furthermore, rapid pain relief, regression of other symptoms, minimally invasive technique and shorter hospitalization seem to be important features as compared with conservative and surgical treatment modalities.

Seminal vesicle abscess: a case report and review of literature

Seminal vesicle abscess, a rare urologic entity, is usually diagnosed with computerized tomography (CT) scan. We report a case of seminal vesicle abscess that required a transrectal ultrasonography to confirm the diagnosis. An analysis of 20 cases of seminal vesicle abscess reported in the literature is also reviewed.

Efficacies of various antimicrobial agents in treatment of Staphylococcus aureus abscesses and correlation with in vitro tests of antimicrobial activity and neutrophil killing

A rabbit perforated-capsule model was utilized to study antimicrobial efficacy in treating 2-week-old Staphylococcus aureus abscesses. Animals received either ciprofloxacin (30 mg/kg), cefazolin (100 mg/kg), or ciprofloxacin (30 mg/kg) plus rifampin (20 mg/kg) every 8 h for 8 days or no antibiotic. Antibiotic levels within the abscess exceeded the MIC for the test organism. At the end of treatment, ciprofloxacin was no more effective than the control, animals receiving cefazolin had a mean log10 fall of 2.41 CFU/ml, and animals receiving ciprofloxacin plus rifampin had a mean log10 reduction of 5.06 CFU/ml (P = less than 0.01). Six days after completion of therapy, all abscesses in animals receiving ciprofloxacin plus rifampin were culture negative. Surviving organisms in animals receiving ciprofloxacin or rifampin did not develop resistance to the treatment antibiotics. In vitro time-kill curves performed with logarithmic- and stationary-phase organisms in broth, serum, and abscess fluid supernatants did not correlate with the in vivo results. Neutrophil killing studies of S. aureus pretreated with antibiotics revealed greater killing of organisms pretreated with ciprofloxacin plus rifampin than of those pretreated with cefazolin or ciprofloxacin alone. In conclusion, ciprofloxacin plus rifampin was effective therapy in this staphylococcal abscess model, compared with the moderate efficacy of cefazolin and no effect observed with ciprofloxacin alone. Enhanced neutrophil killing of S. aureus pretreated with antibiotics may be an important mechanism by which bacteria are killed in suppurative infections.
