[Retroperitoneal marsupialization of renal cysts]

The use of minimal invasive surgery in urology continue to increase. Retroperitoneoscopic approach in performing minimal invasive surgery of retroperitoneum shortens the duration of operation in comparison with transabdominal approach, with minimal risk of intraabdominal complications. We described the use of the retroperitoneoscopic approach to the upper pole of a kidney for marsupialization of a symptomatic renal cyst. The procedure was minimally traumatic, morbidity was negligible and the patient was discharged from the hospital the third day after the operation. We believe that retroperitoneoscopic management of giant symptomatic renal cysts will be applicable, together with other existing methods.
