The effect of ureteral obstruction on the course of renal candidiasis in a rat model was studied, using both normal and diabetic Sprague-Dawley rats, and a clinical isolate of Candida albicans. Diabetes was induced by streptozotocin injection 1 week prior to inoculation and transabdominal ligation of the left ureter. On day 9 post inoculation, mean titers of Candida were similar in right and left kidneys of obstructed rats. Mean left renal titers for obstructed and control rats were similar (log10 2.68 CFU/g +/- 0.73 (SE) vs. log10 2.21 +/- 0.09, P greater than 0.01). Diabetes produced higher renal titers of Candida, regardless of the presence of ureteral obstruction (log10 5.74 CFU/g +/- 0.57 (SE) vs. log10 2.21 +/- 0.09, P less than 0.01). Animals treated for one week with amphotericin B showed a marked difference in Candida titers between obstructed and control animals (log10 4.14 CFU/g +/- 0.45 (SE) vs. 1.57 +/- 0.38) for both kidneys, and between obstructed and nonobstructed kidneys in the same animals.

We report on 5 neonates with obstructive urinary tract candidiasis in whom percutaneous nephrostomy had a major role in management. The advantages of percutaneous nephrostomy in this setting include prompt drainage of the obstructed renal pelvis or ureter, direct access to obtain specimens from the renal pelvis to confirm the diagnosis, direct irrigation of the fungus balls with amphotericin B and an access route for fragmentation of fungus balls by guide wire manipulation. In 3 cases percutaneous placement of the nephrostomy tube was successful in obtaining and maintaining access to the renal pelvis, while in 2 surgical intervention was required because of problems maintaining placement of the percutaneous catheters. Percutaneous nephrostomy with antegrade amphotericin B irrigation, coupled with systemic antifungal therapy, is the mainstay of treatment. The usefulness of ultrasonography in the early diagnosis of renal candidiasis also is emphasized.

A sixteen day old infant developed candiduria after surgery on a single functioning, hydronephrotic kidney with ureteropelvic junction stenosis. Masses of candida albicans caused obstruction of the ureter with acute anuria. Endoscopic relief of the obstruction together with aggressive antifungal therapy led to irradication of the fungal infection. This case history emphasizes the fact that candida infection in early childhood should be evaluated carefully. Unfortunately no guidelines are yet available for the indications and the preferred mode of treatment, and length of therapy of infantile renal candidiasis.

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.

Nineteen patients with benign ureteric strictures were treated by an antegrade approach. Following percutaneous nephrostomy, the strictures were dilated by either tapered dilating catheters or angiographic balloon catheters and temporarily stented using internal double J ureteral stents. The strictures were most commonly caused by calculous disease, post-radical hysterectomy and inflammatory disease, including tuberculosis and candidiasis. The majority (73%) were situated in the distal third of the ureter. Short strictures less than 3 cm in length were present in eight patients (36%) while in ten patients the age of the stricture was less than three months. In two patients, the strictures were too severe and could not be crossed by guidewires and those patients required reimplantation of the ureter. In 16 patients, the strictures were successfully dilated. Follow-up period ranged from five months to twenty-six months (mean 13 months). There were no complications directly related to dilatation. The aetiology and age of an ureteric stricture are the most important factors in predicting the success of ureteric dilatation. This review demonstrates that early treatment of strictures by percutaneous techniques, even those that may be devascularised by the underlying disease process, should usually be successful.

Candidosis of the ureter and the bladder is an infrequent complication after renal transplantation. A case occurring early after kidney transplantation is reported in a patient presenting with candiduria. Ultrasound examination detected several fungal bezoars, presenting as a proliferating, avascular lesions, located within the ureter and the bladder. It allowed to demonstrate the rapid extension of lesions, in spite of a medical treatment, leading to a successful endoscopic removal of fungus balls.

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.

A 36-year-old patient was admitted to the emergency department with complaints of severe flank pain, nausea, vomiting, anuria, and general illness. Five months earlier, we had placed a subcutaneous pyelovesical prosthesis (Detour; Porges) of the ureter for treatment of a chronically dilated upper urinary tract in a solitary right kidney previously treated by double-J stenting. Ultrasonography of the right kidney revealed severe hydronephrosis. A percutaneous nephrostomy catheter was placed, and antegrade pyelography showed complete obstruction of the prosthesis. Urinalysis and culture demonstrated a Candida infection. A systemic antimycotic was administered, and fluid management was started. On the third day, diuresis appeared, and antegrade nephrostomography confirmed patency of the bypass.

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.

Giant inguinoscrotal hernia are uncommon in developed countries. They are defined as 'hernias that extend below the midpoint of the inner thigh in the standing position'. As well as the classic complications of inguinoscrotal hernia, patients will encounter difficulty in walking, sitting or lying down, with mobility dramatically restricted. patients will also often develop cutaneous complications such as irritative eczema, candidiasis, and gangrene or ulcers. When the ureter or bladder are contained in the hernia's sac, recurrent urinary tract infections may also occur.
