Objective:
According to current concepts, multilocular renal cysts are the most benign type of embryonary tumors by contrast to wilm's tumor. Our experience with multilocular renal cyst is presented herein.
Methods:
12 patients (4 boys, 6 adult females and two males) were diagnosed and treated for multilocular renal cyst. One of the adult male patients had an adenocarcinoma located on one of the cysts. Ten patients underwent nephrectomy and two patients were treated by conservative surgery.
Results:
At 9 years' mean follow-up, no tumor recurrence has been observed.
Conclusions:
In the adult patient, all segmental, large and multiloculated cystic masses with a homogeneous content that do not compromise the rest of the parenchyma or adjacent organs except by compression, are suggestive of a multilocular cyst. Conservative surgery is the most reasonable therapeutic option if the foregoing is suspected. This condition has a very good long-term prognosis.
