“…We evaluated renal or retroperitoneal abscess with CT or US [12] . Especially in representative findings of CT, we have a ringenhanced and/or internal low-density area in the CT scan identified as an abscess by experienced radiologists (longer than 15 years after obtaining radiologists board).…”

Introduction: This study examined the risk factors for initial treatment failure in renal or retroperitoneal abscess as a multicenter study. Materials and Methods: This retrospective analysis investigated consecutive patients with renal or retroperitoneal abscess who were hospitalized in Japan. The outcomes of these patients were classified into “cured” and “failure or recurrence.” The potential clinical risk factors examined were abscess size, diabetes mellitus, major organ failure, laboratory data, fever, drainage, and causative organisms, for instance. Results: Of the 74 patients, 40 (54.1%) were diagnosed with renal abscess and 34 (45.9%) with retroperitoneal abscess, 51 (68.9%) were cured by initial treatments, and 23 (31.1%) underwent failure or relapse; 33 (44.6%) were men and 41 (55.4%) were women. In detail, 36 patients were cured by conservative therapy only. Our multivariate analysis data showed that renal failure was the only significant factor for initial treatment failure (p = 0.0281). Conclusions: Our multivariate analysis showed that renal failure was a significant risk factor for initial treatment failure or recurrence.

“…The relative prevalence of GBSI in Asians compared to other races has not been described. In one recent Chinese study of 98 patients with PA, GBS was indeed not isolated [38]. Thirdly, we report successful use of percutaneous drainage to treat large multiloculated PA.…”

Group B streptococcus infections (GBSI) are commonly associated with neonates and pregnant women, but may also affect nonpregnant adults. Among its spectrum of manifestations, perinephric abscess (PA) is exceedingly rare. Comorbid conditions such as diabetes mellitus (DM) and immunosuppression increase the risk of GBSI. We describe a 61-year-old Vietnamese man with compensated alcoholic cirrhosis, who presented with acute encephalopathy following subacute, progressive abdominal pain. He was afebrile and hemodynamically stable. Laboratory data were remarkable for leukocytosis, thrombocytopenia, azotemia, and pyuria. He was found to have two right-sided PA measuring 15 × 10 × 11 cm and 4.6 × 2.7 × 7.8 cm, requiring interval placement of multiple percutaneous drains. Culture from abscesses revealed beta-hemolytic Group B streptococcus (GBS). His course was complicated by contiguous spread to abdominal wall and paraspinal musculature, as well as a new diagnosis of type 2 DM. Along with drainage, a prolonged course of intravenous antimicrobial treatment led to abscess resolution. Given the rising number of unusual clinical presentations of GBSI, this bacteria should be considered as a part of the microbiological differential diagnosis of PA, especially in conditions leading to immunosuppression.

“…Pleural infection secondary to intra‐abdominal sepsis is an important but easily missed clinical entity that poses a diagnostic challenge, especially where respiratory symptoms predominate, and/or underlying sub‐diaphragmatic pathology is clinically silent. Lumbar back pain and fever were the most common symptoms in patients with renal/perinephric abscesses; conversely dysuria/pyuria were uncommon (<10% of patients) .…”

Pleural infection as a complication of ascending urological infection is rare, and the mechanism often unclear. We report a complicated case of pleural infection and perinephric abscess in a patient who presented with a large right‐sided pleural effusion. Pleural fluid culture yielded Morganella morganii, an unusual pathogen in pleuro‐pulmonary infections. Her computed tomography (CT) scan of abdomen showed a right perinephric abscess which extended into the pleural cavity. Review of prior CT imaging suggested a pre‐existing diaphragmatic defect, likely representing a congenital Bochdalek foramen, through which the infection ascended. Successful treatment was achieved with systemic antibiotics, and drainage of both the pleural and retroperitoneal collections. Intra‐pleural tissue plasminogen activator/deoxyribonuclease therapy effectively cleared the residual pleural fluid. Spread of intra‐abdominal sepsis through diaphragmatic defects to the pleural cavity represents a potential source of empyema.
