Abstract

Background: The current study aims to assess the effects of the large simple renal cyst (SRC) surgery on renal function for the first time. Materials and Methods: This case-series study included 22 patients with larger than 50 mm single SRC who underwent laparoscopic cyst unroofing surgery. Twenty-four-hour urinary protein, creatinine, and volume along with plasma creatinine and estimated glomerular filtration rate (GFR) were measured in patients before and 1 month after surgery. Patients underwent abdominopelvic computed tomography-scan without contrast and parenchymal thickness diameter adjacent to the cyst was measured before and after surgery. Results: Mean age and weight of patients were 52.2 ± 8.9 years and 77 ± 10.9 akg, respectively. There was no significant difference between plasma creatinine and GFR before and after surgery (P = 0.25 and 0.37, respectively). Twenty-four-hour urinary volume, creatinine, and protein before and after surgery revealed no significant changes (P = 0.37, 0.08, and 0.31, respectively). The mean improvement of parenchymal thickness diameter after surgery was 10.4 ± 0.7 mm which was statistically significant (P = 0.001). However, it was not correlated with the mean estimated GFR change (r = 0.349, P = 0.13). Conclusions: Although laparoscopic unroofing of renal cyst recovered renal parenchymal thickness noticeably, it did not improve renal function significantly; therefore, the latter factor lonely should not be considered a reason for surgery decision. Observation can be chosen as a safe treatment strategy in large SRCs without concern about renal function. © 2022 Advanced Biomedical Research | Published by Wolters Kluwer-Medknow.
