Primary renal candidiasis is an uncommon disorder. It typically presents as urinary tract obstruction secondary to bezoar in the ureter, progressive oliguria (at times alternating with episodes of diuresis), ureteral colic, passage of tissue- or stone-like material, pyuria, and/or progressive renal failure. The patient described here presented with gross and microscopic hematuria. In our literature review, we found neither of these reported as clinical signs of primary renal candidiasis. With the widespread use of drugs (eg, antibiotics, antineoplastic chemotherapeutic agents, systemic corticosteroids) which facilitate the growth of Candida, primary renal candidiasis should be considered in the patient who presents with hematuria.

A 69-year-old man was transferred to our hospital because of fever and acute renal failure. 5 weeks prior to admission, he was admitted to another hospital and treated with several antibiotics including vancomycin, but fever did not subside and renal dysfunction showed rapid progression. On admission, laboratory findings revealed pyuria, inflammatory changes, acute renal failure, and disseminated intravascular coagulation (DIC). Computed tomography showed left ureteral stone and hydronephrosis. Gallium scintigraphy showed avid uptake in the left kidney. Serum concentration of vancomycin was 57.4 micro/ml. Candida glabrata was isolated from blood, sputum and urine. Under the diagnosis of fungemia and left pyelonephritis, he was treated with micafungin (150 mg/day), gabexate mesilate and insertion of a double-ended pigtail catheter. The above treatment produced regression of systemic inflammation, DIC and acute renal failure. At the last follow-up 3 weeks after discharge, ureteroscopy showed that the ureter stone had already passed but a soft white-yellowish bezoar was detected in the ureter. In this case, neurogenic bladder, poorly controlled diabetes, and long-term antibiotic treatment probably enhanced the development of C. glabrata infection. Antifungal treatment with micafungin is useful in patients with non-albicans Candida infection.

Candidiasis of the lower urinary tract is common in immunocompromised patients. Diabetes and chronic indwelling catheter are two common risk factors for such opportunistic infections. However, upper urinary candidiasis is rare. Further, bilateral synchronous involvement of kidneys and ureter is extremely rare. Treatment usually requires relief of obstruction by percutaneous drainage of the kidney and systemic infusion or local irrigation of antifungal agents. When these measures fail, percutaneous surgical debulking of the fungal bezoar is indicated. We present a case of obstructive anuria due to fungal bezoar in both the pelvicalyceal system and ureter managed by bilateral synchronous endoscopic removal of fungal bezoar.

We describe the first reported case of renal zygomycosis presenting as an isolated fungus ball (bezoar) without renal parenchymal invasion. Since all previous descriptions of renal involvement have discussed tissue invasion, our case is unique in that the infection was confined solely in the renal pelvis and extended to the distal ureter without signs of contiguous renal infection. Our patient later developed renal insufficiency while receiving amphotericin B Lipid Complex (ABLC). The therapy was changed to posaconazole with subsequent clinical, mycologic, and radiographic improvement and the patient has remained free of recurrence 5 years after diagnosis.
