Brief Title: Measurement of Renal Functional Reserve Change In Patients With SRC Before and After Laparoscopic Deroofing
Official Title: Measurement of Renal Functional Reserve Change In Patients With Simple Renal Cysts Before and After Laparoscopic Deroofing
Study ID: NCT03259594
Brief Summary: Renal functional reserve may be improved in patients with simple renal cysts after laparoscopic deroofing.
Detailed Description: Simple renal cysts (SRC) are the most frequent type of cystic renal disease. The prevalence rate of SRCs is about 10% and increases with age. Hypertension and decreased renal functions have been reported to occur more commonly among these patients with SRC and there are no clear guidelines for managing asymptomatic SRCs.Renal functional reserve (RFR) describes the capacity of the intact nephron mass to increase glomerular filtration rate(GFR) from baseline in response to stimuli (e.g., protein load).The investigators hypothesized that RFR may be improved in some patients with simple renal cysts after laparoscopic deroofing despite identical resting glomerular filtration rate (rGFR).The aim of this study is to examine whether there is improvement of RFR in patients with simple renal cysts after laparoscopic deroofing.
