ABSTRACT
With increased use of sodium-glucose co-transporter 2 (SGLT2) inhibitors as antidiabetic agents, the risk of serious fungal urinary tract infection (UTI) may be increased. We present the case of a 67-year-old Caucasian female who was admitted for emphysematous pyelitis and found to have a fungal ball in the renal pelvis. Candida glabrata was cultured and the patient was managed with percutaneous nephrostomy tube placement and antifungal treatment. The fungal ball persisted and required surgical removal with ureteroscopy and basket extraction. Fungal balls can be a difficult sequelae of UTIs requiring a combination of antifungal and surgical intervention for definitive management.

OBJECTIVE. The purpose of this article is to review the spectrum, etiopathogenesis, clinical presentation, imaging features, differential diagnoses, and management of emphysematous infections of the abdomen and pelvis. CONCLUSION. Emphysematous infections are associated with high morbidity and mortality and thus need urgent medical and surgical interventions. CT is the most sensitive modality to detect gas; CT provides definitive diagnosis in most cases and can depict the extent of involvement.

Diabetes mellitus (DM) is a common disease in Oman as in rest of Gulf Cooperation Council where metabolic syndrome is of high prevalence. DM is a foremost risk factor for urinary tract infections (UTIs). It is also linked to more complicated infections such as emphysematous pyelonephritis (EPN), emphysematous pyelitis (EP), renal/perirenal abscess, emphysematous cystitis, xanthogranulomatous pyelonephritis, and renal papillary necrosis. The diagnosis of these cases is frequently delayed because the clinical manifestations are generic and not different from the typical triad of upper UTI, which include fever, flank pain, and pyuria. A middle-aged female with DM and chronic kidney disease stage IV was admitted with recurrent UTI with extended-spectrum beta-lactamase-producing Escherichia coli. At presentation, she was afebrile, clinically stable, had no flank pain and there was no leukocytosis. Laboratory test for C- reactive protein done twice and was only mildly elevated at 7 and 11 mg/dL. A computed tomography scan of kidney-ureter-bladder (CT-KUB) was recommended and reported as "no KUB stone but small atrophic left kidney with dilatation of the pelvicalycial system and ureter and the presence of air in the collecting system suggestive of EP." Thus, commonly associated with DM, especially in females, debilitated immune-deficient individuals, and patients harboring obstructed urinary system with infective nidus. Air in the kidney is not always due to EPN. UTI with a gas-producing organism can ascend to the kidney in the presence of vesicoureteral reflux.

OBJECTIVE: In the present study various tissues of pigs were investigated for the presence of histopathologic lesions after an experimental infection with Haemophilus (H.) parasuis serovar 5. MATERIAL AND METHODS: Conventional pigs (n = 36) were divided into a control group B (n = 9) and a challenge group A (n = 27), which was infected intratracheally. Pigs that did not die prior to study termination were euthanized on day 14 post inoculation. Postmortem samples of the lung, heart, liver, kidney, spleen, left tarsal joint capsule and brain were collected. RESULTS: All but one pig with detectable histopathologic lesions (n = 11) showed typical macroscopic changes. Histopathologic examination of all tissue samples identified pyelitis (n = 10), synovitis (n = 7) and meningitis (n = 7) and all those animals were euthanized prior to study termination. No histopathologic lesions were found in pigs of the control group. The correlations between pyelitis and meningitis, pyelitis and synovitis and synovitis and meningitis were significant (p < 0.001). No significant correlation could be observed between the histopathologic and the clinical examination of the joints. The investigation of samples from the joints by PCR was not significantly correlated with the observed synovitis. The clinical observation of neurologic signs was significantly correlated with meningitis (p = 0.03). A significant correlation (p < 0.001) could be detected between meningitis and the detection of H. parasuis by PCR in brain samples. CONCLUSIONS: H. parasuis constantly causes clinical signs and pathologic lesions as soon as it infects the brain while it can infect the joints without causing histopathologic lesions. Pigs with histopathologic lesions do not always show typical clinical signs. Only few studies described the finding of kidney lesions in pigs with Glässer's disease and this is the first study to describe a pyelitis in pigs experimentally infected with H. parasuis. The observed pyelitis mainly occurred in acute cases.

We present the case of a 49-year-old woman with poorly controlled diabetes mellitus of ten years' duration. She presented to the emergency department with nonspecific left lower abdominal pain. Ultrasonography showed mild left renal hydronephrosis, but the cause was not demonstrated. Computed tomography (CT) showed a swollen left kidney with a mildly dilated collecting system containing gas and dense fluid, confirming the diagnosis of emphysematous pyelitis. Management consisted of emergency antegrade nephrostomy drainage and parenteral antibiotics. Subsequently, the patient made a good recovery and was well when discharged home after two weeks. Gas-forming infections of the genitourinary tract carry high mortality and morbidity, and usually occur in patients with poorly controlled diabetes mellitus. Escherichia coli is the most common microorganism. This case emphasises the importance of CT in making an early diagnosis of emphysematous pyelitis, which allows prompt treatment and improves prognosis.

Alkaline-encrusted pyelitis is a urinary infection characterised by encrustations in the wall of the urinary tract. It is caused by fastidious growing urea splitting microorganisms mainly Corynebacterium group D2. The diagnosis is easily missed and should be evoked on basis of sterile pyuria, alkaline urine pH and calcifications of the urinary excretion ways on the CT scan and then confirmed by prolonged culture on appropriate media. The authors report here the case of a patient who died after a delayed diagnosis from recurrent septic urinary infections.

BACKGROUND: Corynebacterium urealyticum is a cause of urinary tract infection and encrusting cystitis or pyelitis. Information about this infection in renal transplant recipients is based on case reports. We communicate the first prospective epidemiological study for this population. METHODS: We selected a cohort of 163 renal transplant recipients who were screened for urinary tract infection due to C. urealyticum. Long-term incubation and special media were used for culture of C. urealyticum. The cohort was observed for a mean of 26.2 months (standard deviation, 8.7; range, 1-36 months). Risk factors and outcomes were assessed. RESULTS: At baseline, 16 (9.8%) of 163 patients had C. urealyticum bacteriuria (6 were asymptomatic, 9 had acute cystitis, and 1 had encrusting pyelitis). Independent risk factors (assessed by multivariate analysis) for urinary tract C. urealyticum infection were: antibiotic administration during the previous month (odds ratio, 8.04; 95% confidence interval, 1.57-41.06; P = .012), history of nephrostomy (odds ratio, 51.59; 95% confidence interval, 3.62-736.06; P = .004), and skin colonization (odds ratio, 208.35; 95% confidence interval, 21.54-2015.22; P< .001). Presence of urinary tract infection symptoms for >1 month (odds ratio, 27.7; 95% confidence interval, 2.55-300.5; P = .006) and obstructive uropathy (odds ratio 25.9; 95% confidence interval, 4.43-152.31; P < .001) were more frequent during follow-up in patients with C. urealyticum bacteriuria. CONCLUSIONS: When specifically tested for, C. urealyticum bacteriuria is more prevalent than previously thought in renal transplant recipients, and it is closely related to obstructive uropathy. Future studies are necessary to establish the relevance of treating the infection during follow-up after renal transplantation.

Diagnosis of encrusted pyelitis in predisposed patients is difficult. The bacteriology laboratory must be specifically asked to perform the appropriate tests. Computed tomography without injection is very important for diagnosis and follow-up. Conservative treatment is essential insofar as possible. Long-term follow-up is also necessary.

Encrusted cystitis is a very rare chronic inflammatory disease of the bladder characterized by precipitation and incrustation of phosphate and ammonium-magnesium salts on the vescical mucosa, caused by urinary infection due to urolithic microorganisms. Corynebacterium urealyticum or Corynebacterium group D2, a multiple antibiotic-resistant urea-splitting bacterium, is the most frequently incriminated aetiology. We report a case of a 57-year-old man affected by systemic erythematosus lupus with a long history of dysuria and suprapubic pain who underwent percutaneous nephrostomy drainage with urethral stenting for lupoid obstructive uropathy. Before the diagnosis of encrusted cystitis by Corynebacterium urealyticum was established, the patient underwent five cystoscopies to remove the plaques and multiple unsuccessful antibiotic treatment courses. Eventually the infection was definitively cured after a two-week course with intramuscular teicoplanin.

Alkaline encrusted pyelitis is an infectious disease characterised by encrustations in the wall of the upper urinary tract, surrounded by severe inflammation. Destruction of native kidneys and kidney grafts may occur, resulting in end stage renal failure. Corynebacterium group D2, an urea splitting microorganism, is nearly exclusively associated with this disease. The most important predisposing factors are previous urological procedures and an immunosuppressed state. In a suggestive clinical context, diagnosis should be made with unenhanced computed tomography findings and bacteriologic isolation of the responsible microorganism. The treatment is threefold: appropriate antibiotic therapy, by preference with glycopeptides, acidification of urine and chemolysis, and if needed, surgical removal of encrustations. We report the case of a patient who was diagnosed with this rare condition and could escape maintenance dialysis after correct diagnosis was made and conservative treatment was started using antibiotics and combined oral and local acidification.

OBJECTIVES: To report our experience with the management of encrusted cystitis and pyelitis (EC and EP) in the pediatric population. EC and EP are well-known entities in adults but are rarely identified in children. They consist of mucosal encrustations and are due to specific microorganisms. METHODS: Between 1996 and 2001, 4 children with a mean age of 9 years (range 4 to 13) were treated for EC (n = 2), EP (n = 1), and EC and EP (n = 1). The latter was a kidney transplant recipient. We retrospectively evaluated the clinical characteristics of the patients and the results of conservative management. RESULTS: The delay between the beginning of the symptoms and the diagnosis was longer than 1 month in all cases. The diagnosis of EC was not evoked and was made during cystoscopy in all cases. EP was diagnosed during pyelotomy in 1 patient because it was evoked and confirmed by computed tomography scan in the kidney transplant recipient. Corynebacterium urealyticum was identified in the urine of all patients. EC was treated by antibiotics and endoscopic debulking, and EP was treated by antibiotics and local acidification. The duration of antibiotic therapy was between 1 and 6 months. The tolerance to local acidification of the kidneys was poor. Cure was achieved in 3 cases, but the treatment of EP failed in the kidney transplant recipient and graft removal was decided after 6 months of failed management because intractable febrile urinary tract infections became life threatening for the patient. CONCLUSIONS: EC and EP are uncommon in children; however, these diseases must be considered. They must be diagnosed rapidly and require, if possible, conservative management. Nevertheless, kidney loss can occur in transplant recipients with EP.

OBJECTIVE: This is a case of Encrusted Pyelitis (EP) caused by Corynebacterium urealyticum (CU) in a patient who had undergone a cystectomy and Bricker type urinary diversion 28 months beforehand. METHODS/RESULTS: After the immediate post-operative period no urinary catheterisation or any other urological procedure was performed on the patient. Before surgery, the patient presented non functional of the right kidney, secondary to a lithiasic obstructive uropathy. Clinical symptoms were deteriorated renal function, anuria, haematuria, pyrexia and left lumbar pain. It was suspected that the patient had this pathology and this was fundamental in diagnosis. Helicoid CT was the principal method used to show calcification plaques on the wall of the left renal pelvis, and selective culture of CU confirmed the diagnosis. Early commencement of treatment with vancomycin at an initial dosage of 500 mg/12 hours, and subsequent adjustment of dosage according to blood drug levels, achieved negative urine culture within a fortnight. Oral acidification was effected using acetohidroxamic acid 125 mg/12 hours, and it was continued until CT confirmed the disappearance or considerable reduction of the pyelic calcification plaques. CONCLUSION: The presence of EP in patients with urinary diversion is a matter worthy of consideration, even in patients who have not undergone recent urological procedures. Awareness of risk factors and early commencement of effective treatment may improve the prognosis of these patients.

Tissues from ureter and renal pelvis of 18 sows naturally (n = 15) and experimentally (n = 3) infected with Actinobaculum suis (former Actinomyces, Eubacterium suis) were studied using light and scanning as well as transmission electron microscopy. The results were compared with the findings from 11 clinically healthy sows as controls. The lesions in both the ureter and renal pelvis of naturally and experimentally infected animals were similar. In severe cases there were necrotizing ureteritis and pyelitis with accumulation of bacterial colonies in some cases. Several superficial epithelial cells were found phagocytosing necrotic debris. In mild cases the main lesions included epithelial cell hyperplasia, desquamation of the superficial epithelial cells and goblet cell metaplasia with intraepithelial cyst formation. The goblet cells were found in the superficial as well as in the intermediate cell layers. Generally, it was observed that severe purulent ureteritis and pyelitis/ pyelonephritis in sows were to be expected only in mixed infection of A. suis with other bacteria. The findings were compared and discussed with the changes in the infected urinary bladder of sows and the alterations induced by urinary tract infection in man.

We report on two new cases of encrusted pielitis, a lithiasic disease of infectious ethiology--Corynebacterium of D group-. The clinic diagnostic is difficult and this disease develops in immunosuppressed patients, mainly in renal transplanted ones. One of our two cases is diagnosed in a patient with a transplanted kidney and the other one develops the disease within her native kidneys. We remark on the clinic features and therapeutic options.
