Most fungal infections of the urinary tract involve the drainage structures rather than the kidney parenchyma. They usually occur in patients with diabetes or other chronic debilitating diseases and in the presence of urinary stasis. Conglomeration of fibrillar hyphae results in fungal balls which produce nonopaque filling defects in the renal pelvis, ureter, or bladder. Such fungal ball colonies were demonstrated by percutaneous (antegrade) pyelography in the upper urinary tract in two cases. A percutaneous nephrostomy was performed in one patient to provide drainage of pus in the renal pelvis.
大多数泌尿道真菌感染累及引流结构而非肾实质。它们通常发生于糖尿病患者或其他慢性消耗性疾病患者以及存在尿潴留的情况下。纤维状菌丝的聚集形成真菌球，在肾盂、输尿管或膀胱内产生不透光的充盈缺损。在两例上尿路病例中，经皮（顺行）肾盂造影显示了此类真菌球菌落。对一名患者实施了经皮肾造瘘术以引流肾盂内的脓液。
