[Kidney carbuncle: diagnostic, bacteriological and therapeutic considerations. Apropos of 11 cases].

Renal carbuncle is a cortical lesion following bacteremia, occurring in patient without any urologic known problems. The analysis of 11 consecutive renal carbuncles showed that one should consider the diagnosis of renal carbuncle in young patients with flank pain, fever, and absence of significant leucocyturia. Our study confirms that renal carbuncle is always caused by staphylococcus aureus and that treatment is based on appropriate antibiotherapy. Isolation of the bacteria was difficult unless ponction of carbuncle under ultrasound control was performed. The usefulness of ultrasonography for the diagnosis of renal carbuncle and for its distinction from other suppurative renal lesions is emphasized.

Renal carbuncle: early diagnosis by retroperitoneal ultrasound.

The diagnosis of renal carbuncle has been prolonged from the time of onset of symptoms to the institution of treatment producing a significant rate of mortality. The use of retroperitoneal ultrasound is demonstrated as a noninvasive method for making an earlier diagnosis of renal carbuncle than has been afforded by more conventional means. This report illustrates the technique of nephrosonography and briefly reviews the medical and surgical approaches to this disorder. To our knowledge, this is the first reported case wherein ultrasound, and not pyelography, demonstrated a carbuncle without the aid of invasive arteriography.

Renal carbuncle: diagnosis and management.

Six cases of renal carbuncle are presented. Nonstaphylococcal carbuncles now greatly outnumber those of staphylococcal origin. Diagnostic modalities are discussed. No radiologic or laboratory investigation is specific, but the diagnosis should be suspected in most cases if adequate attention is given the patient's signs and symptoms. Surgical treatment is recommended.

Conservative management of renal carbuncles in children.

Renal carbuncles have traditionally been treated with surgical drainage and appropriate antibiotic therapy. Recently, 2 pediatric patients with well-documented renal carbuncles were treated with antibiotic therapy alone. Close follow-up documented complete resolution in both cases. Late studies showed no evidence of renal scarring or functional compromise.

[Kidney carbuncle in a 9-year-old boy].

Report on a 9-year-old boy with right-sided renal carbuncle. The symptoms, diagnosis and treatment of the renal carbuncle are described. The possibility of maintaining the function and reconstructing the kidney through fibrin adhesive is discussed.

[Epidemiological situation of human carbuncle in Upper Volta (author's transl)].

After the statistical statement concerning human carbuncle in Upper Volta in 1976, 1977 and 1978, the authors report their clinical and epidemiological ascertainments observed during the opportunity of four surveys. Among the cutaneous forms, cephalic localization is the most frequently observed. Visceral forms are essentially digestive, sometimes respiratory, never neurological. In its voltaic foci (grounds made of clayey alluvium, regulatory flooded), carbuncle stretches to endemic-sporadic forms with epidemiological peaks. It does not exist any parallelism between the importance of breeding and human disease, which is much more frequent during the rainy season than during the dry one. Prophylactic measures are proposed: ruminant and hog vaccination in endemic areas, preceded by an information and education campaign for the health.

[Surgical treatment of carbuncles].

In the treatment of extensive and progressing forms of carbuncles in the phase of purulent-necrotic inflammation the method of choice should be the operation of dissection within the limits of healthy tissues. When it is possible to approximate the wound borders after dissection of carbuncles, it is expedient to finish the operation by putting in primary stitches, when it is not possible, free skin autoplasty should be performed.

Renal carbuncle: comparison between surgical open drainage and closed percutaneous drainage.

This article represents a retrospective study of 12 patients with renal carbuncle treated at the combined urological services of The Mason Clinic in Seattle, Washington, and Madigan Army Medical Center in Tacoma, Washington. All patients were initially treated with antibiotics. Two recovered without further treatment. Of the 10 patients who failed to respond, 2 underwent nephrectomy for nonfunctioning kidneys, 4 underwent closed percutaneous drainage, and 4 underwent surgical open drainage. All patients treated with open surgical drainage recovered and retained functioning kidneys. Of the 4 patients who underwent closed percutaneous drainage, 2 failed to respond and required subsequent emergency nephrectomy because of sepsis. The authors believe that renal exploration and open drainage should be the initial definitive mode of surgical treatment of renal carbuncle in those patients who fail antibiotic therapy alone.

Renal carbuncle: simulation of tumor response to epinephrine.

A case of renal carbuncle with unusual angiographic findings is presented. The abscess showed abnormal vessels on selective angiogrpahy which were enhanced after intra-arterial epinephrine. New foci of abnormal vessels were also seen on the postepinephrine angiogram.

Renal carbuncle: the use of ultrasound in its diagnosis and treatment.

The use of ultrasound in the diagnostic and therapeutic management of 5 patients with renal abscesses is described. A spectrum of ultrasonic findings was noted, with the majority of the lesions being anechoic (3 cases). However, a few lesions showed a mixed pattern (2 cases). Ultrasonic aspiration of abscess fluid for culture and sensitivity obviated an operation in 1 case. For the first time, ultrasonically guided, percutaneous, indwelling catheter drainage of a renal carbuncle is reported. Since the patient had failed to respond to systemic antibiotic therapy this technique saved the patient from undergoing an operation. The clinical and ultrasonic findings in the 6 previous case reports of abscesses are reviewed.

Abscess

Acute renal carbuncle.

A renal carbuncle (cortical abscess) is an important and treatable consideration in the differential diagnosis of renal mass lesions. Diagnosis is accomplished using a combination of clinical, urographic, arteriographic and ultrasonographic findings. Ultrasound is an accurate and less invasive alternative to arteriography. Needle aspiration of the abscess contents may give a bacteriologic diagnosis. Non-surgical treatment with antibiotics alone may be curative. Five cases are presented, and clinical and radiologic features are reviewed.

Antibiotic treatment of renal carbuncle.

Renal carbuncles in seven young males were successfully treated with long-term administration of penicillinase-resistant antibiotics. Selective renal arteriography provided an accurate means of diagnosis and permitted a trial of medical therapy. All patients experienced a prompt and sustained clincial remission; surigical exploration was thus obviated in all but one instance, in which post-treatment radiographic changes persisted.

Conservative approach in treating acute renal carbuncle.

During the years 1980-82 seven patients with renal carbuncles successfully underwent conservative treatment with antibiotics alone. Early diagnosis was made using excretory urography and nephrotomography, ultrasound and computerized tomography scan. Follow-up studies showed a normal kidney in six of the seven patients. One patient had a clinical remission, but ultrasound follow-up showed a small area in the right kidney with a few low-level echoes, representing focal scarring.

[Treatment of carbuncles].

The active aspiration of the wound is a method of mechanical antiseptics responsible for the removal of pyo-necrotic masses and accelerates the process of the wound cleaning. The method was used for the treatment of 90 patients, in 84 of them the carbuncles were opened. The results were good.

Adolescent

[Renal carbuncle (abscess)].

The authors report a case of renal carbuncle at 44 year old women. The patient has been presented with high temperature and strong pain in the left costovertebral angle. Diagnosis was based on ultrasonography, intravenous urography and computed tomography and confirmed by percutaneous punction. The patient has been successfully cured by percutaneous drainage and parenteral application of antibiotics.

Renal carbuncle: unusual cause of postpartum febrile morbidity.

Obstetricians should be alert for medical problems disguised as postpartum complications. A patient with renal carbuncle which presented as postoperative fever is described. The lesion was treated by percutaneous drainage. A brief summary of the differential diagnosis of renal abscess is presented.
