Laparoscopic deroofing of large renal simple cysts causing gastric symptoms.

Widespread use of ultrasonography and computerized tomography of the abdomen result in the detection of a large number of renal mass lesions. Most of these are simple renal cysts, which do not need any further evaluation or follow up unless symptomatic. Simple renal cysts can be diagnosed with certainty if the treating physician or surgeon is aware of these features and can avoid unnecessary urology referral, patient anxiety, inconvenience and expense. Symptomatic cysts and complex renal cysts need further evaluation and intervention. We present the case of large symptomatic renal cysts persisting after aspiration sclerotherapy, which were managed by deroofing the cyst laparoscopically. Laparoscopic deroofing is rapidly becoming accepted as the surgical intervention of choice for symptomatic renal cysts persisting after aspiration sclerotherapy.
