Fungal infections of the urinary tract have a predilection for drainage structures rather than for the renal parenchyma. Of the causal factors, diabetes mellitus, immunosupressed states, AIDS and prematurity are those most commonly encountered. The case of a young, diabetic man whose chief clinical presentation was dysuria is described. On further examination he was found to harbour fungal balls in the right kidney. Radiological manifestations of acute pyelonephritis were also present. Although primary renal candidiasis is often commensurate with systemic fungaemia, he displayed none of the clinical features of disseminate infection and, hence, was treated conservatively with oral antifungal agents. Fortuitously, spontaneous passage of fungal particulate matter in urine was later reported.

A case of acute emphysematous pyelonephritis (EPN) caused by Aspergillus fumigatus is reported in a non-diabetic patient, who did not apparently have any risk factors for fungal infection. The patient refused any surgical intervention and was successfully treated with liposomal amphoteracin-B and 5-flucytocin and achieved complete recovery.

Emphysematous renal tract disease (ERTD) is a rare necrotizing infection of renal parenchyma and/or urinary tract caused by gas producing organisms. A case of acute emphysematous renal tract disease (ERTD) (emphysematous pyelonephritis along with emphysematous cystitis) caused by Aspergillus fumigatus in a non-diabetic patient, who did not apparently have any risk factor for fungal infection, is presented. Patient had refused for any surgical intervention. He was treated successfully with liposomal amphotericin B and 5-flucytosin and achieved complete recovery. Various causes of ERTD and available therapeutic options are discussed.

We present an interesting and rare case of a diabetic patient who developed extensive unilateral emphysematous pyelonephritis (EPN) which was caused by fungal infection. The diagnosis was confirmed on computed tomography (CT) scan of the abdomen. Repeated urine cultures grew Candida albicans but no other organisms were isolated. The patient remained febrile and unwell despite parenteral broad spectrum antibiotics and antifungal treatment. She underwent nephrectomy and then made a good clinical recovery.

Fungal infections of the urinary tract are increasing in incidence, mostly because of the increasing use of antibacterial agents and indwelling urinary catheters. This review will focus mainly on the spectrum of genitourinary infections caused by Candida spp., including asymptomatic candiduria, cystitis, pyelonephritis, and renal candidiasis. Special emphasis will be placed on the therapeutic approach to the various clinical entities. Other fungal infections, such as urinary aspergillosis and cryptococcosis will be discussed briefly.

With prolonged survival and aging of the HIV-infected population in the era of antiretroviral therapy, biopsy series have found a broad spectrum of HIV-related and co-morbid kidney disease in these patients. Our study describes the variety of renal pathology found in a prospective cohort of antiretroviral-experienced patients (the Manhattan HIV Brain Bank) who had consented to postmortem organ donation. Nearly one-third of 89 kidney tissue donors had chronic kidney disease, and evidence of some renal pathology was found in 75. The most common diagnoses were arterionephrosclerosis, HIV-associated nephropathy and glomerulonephritis. Other diagnoses included pyelonephritis, interstitial nephritis, diabetic nephropathy, fungal infection and amyloidosis. Excluding 2 instances of acute tubular necrosis, slightly over one-third of the cases would have been predicted using current diagnostic criteria for chronic kidney disease. Based on semi-quantitative analysis of stored specimens, pre-mortem microalbuminuria testing could have identified an additional 12 cases. Future studies are needed to evaluate the cost-effectiveness of more sensitive methods for defining chronic kidney disease, in order to identify HIV-infected patients with early kidney disease who may benefit from antiretroviral therapy and other interventions known to delay disease progression and prevent complications.

Isolated renal infections with fungal organisms of the class Zygomycetes are rare, but these infections are most frequently seen in patients who are immunocompromised. We report the case of a 45-year-old African American man who presented with symptoms of right-sided pyelonephritis, including fever, dysuria, and flank pain. The patient's history was significant only for sickle cell trait, and no evidence of immunosuppression was identified. Renal ultrasound imaging revealed a hypoechoic lesion in the superior pole of the right kidney, and the radiologic differential diagnoses included neoplasm, abscess, and infarct. Urine cultures were negative, but urinalysis showed white blood cells, which were too numerous to count. A computed tomography scan of the abdomen and pelvis performed 2 weeks after the initial presentation showed a slight increase in the renal mass, despite antimicrobial therapy, and a right nephrectomy was subsequently performed. On gross sectioning, an 8.5-cm well-circumscribed lesion was identified in the upper pole of the kidney. Microscopic sections showed extensive necrosis of the renal parenchyma, and, in areas of both infarcted and viable renal tissue, large, broad, aseptate fungal hyphae with irregular branching. Angioinvasion with associated thrombosis was seen in the renal tissue. The morphologic features of the organism were most compatible with that of a zygomycete. No evidence of disseminated fungal disease was identified on imaging studies. This case represents a successful outcome of a rarely reported isolated renal zygomycosis in a patient with no known underlying risk factors for the infection and illustrates the wide range of clinical presentations with which zygomycotic infections may present.

Fusarium infections are important problem worldwide, cause a broad spectrum of infections in human including superficial infections as well as locally invasive and disseminated infections. We report a rare case of perinephric abscess caused by Fusarium chlamydosporum in a child who had a recent episode of pyelonephritis. This case illustrates the ever increasing spectrum of rare but offending pathogenic fungi in an immunocompetent host. Fungal infections should always be suspected in patients having one or the other underlying risk factor or who are unresponding to antibacterial therapy. Early diagnosis of infection with a specific pathogen may lead to changes in antifungal therapy and may be critical for an improved outcome.

Mucormycosis is a rare fungal infection often seen in immunocompromised hosts. Isolated renal mucormycosis may however present in immunocompetent children as renal failure and has a uniformly poor prognosis if not detected and treated early into the course of illness. We present a 3-year-old boy with unrelenting pyelonephritis in whom serial urine cultures done were negative. A final diagnosis of isolated renal mucormycosis was made by magnetic resonance imaging and renal biopsy.

Endobronchial fungal infection (EBFI) is a rare form of pulmonary fungal infection that especially affects immunocompromised patients. Furthermore, EBFI resulting in obstruction of the main bronchus is extremely rare. With the development of bronchoscopic techniques, rare cases of EBFI have been reported. A 68-year-old female was referred to the Department of Pulmonology for confusion and obtundation. The patient was diagnosed with septic shock due to acute pyelonephritis followed by obstructive EBFI. We performed bronchoscopic biopsy and endobronchial aspiration for culture. Biopsy showed yeast-like fungus and Candida albicans grew in the culture. EBFI has been under-recognized because of difficulties in confirming the diagnosis. Endobronchial ultrasound-guided transbronchial needle aspiration and bronchoscopy are used to improve the diagnosis of thoracic infection, such as tuberculosis. The role of bronchoscopy in the diagnosis of infectious diseases of the trachea or main bronchi is expected to widen in the future.
