Systemic candidiasis with renal involvement is a rare but well-recogni
zed complication during neonatal intensive care treatment, In addition
to intravenous administration of amphotericin B, decompression of the
renal pelvis and irrigation of the involved kidney with the same drug
through a nephrostomy tube will provide a high concentration of antif
ungal agent with a flushing effect. This procedure is not always possi
ble due to the small size of the neonatal kidneys. We have conceived a
new percutaneous trocar nephrostomy which allows its application dire
ctly in an incubator without using X-rays during a single procedure. I
n 3 cases a bilateral percutaneous nephrostomy was performed directly
in the incubator using a one-step ultrasonically guided maneuver under
local anesthesia. The funguria was successfully eradicated in all cas
es. The availability of a nephrostomy trocar of small dimensions leads
us to an improved renal approach in newborns.
