We reported an uncommun case of 40 years old man, cardiac transplant recipi
ent with chronic renal faillure who consulted for infected left polykystic
renal. The serum creatinine level was 750 mmol/L, and urine culture isolate
d a E. Ecol germe. The abdominopelvic computed tomography showed a billater
al large polykystic renal cortex and suspected the infected cyst in lower p
ole of left kidney. The retroperitoneal laparoscopic nephrectomy was perfor
med confirming a renal invasive aspergillosa. About this case we should hav
e a high index of suspicion for fungal aetiology in kidney infection in tra
nsplant patients and the management of non functioning infected polykystic
kidney can use laparoscopic retroperitoneal nephrectomy. This approach can
offers a minimal morbidity and alternative to open surgery. (C) 2001 Editio
