Long-term results of transperitoneal laparoscopic fenestration in the treatment of simple renal cysts.

The aim of this paper was to assess long-term results of transperitoneal laparoscopic fenestration in the treatment of symptomatic simple renal cysts. Fifteen consecutive patients (7 men, 8 women), with a mean age of 51 years (range, 36-79 years), underwent transperitoneal fenestration of simple renal cysts (SRC) at our institution from 1994 to 2001. Data were collected by reviewing patients' clinical files, conducting telephone interviews regarding symptoms, and followup renal ultrasonography (US).
