Ultrasound-guided percutaneous intracystic deroofing is effective in the treatment of simple renal cysts.

OBJECTIVE

To investigate the efficacy and safety of ultrasound-guided percutaneous intracystic deroofing for the treatment of simple renal cysts.

METHODS

A retrospective study was conducted to analyze the clinical data of 46 patients with dorsal exophytic simple renal cysts treated at the First Affiliated Hospital of Nanchang University between February 2017 and June 2022. The patients were divided into two groups according to the surgical method, with 20 cases undergoing ultrasound-guided percutaneous intracystic deroofing being assigned to the observation group and 26 cases treated by retroperitoneal laparoscopic renal cyst removal included in the control group. The operation time, blood loss, postoperative catheterization time, postoperative drainage tube indwelling time, postoperative hospital stay, and complications were compared.

RESULTS

None of the 46 patients converted to open surgery. The observation group showed significantly less blood loss, shorter operation time, drainage tube drainage time, postoperative hospital stay, and indwelling catheter time than the control group (all P<0.05). The two procedures had a success rate of 100%. There were no statistical significances in K, Na, or serum creatinine between the two groups (all P>0.05). All patients were followed up (3 to 6 months) after surgery, and no cyst recurrence was found by imaging examination.

CONCLUSIONS

Ultrasound-guided percutaneous intracystic deroofing of renal cysts is worthy of clinical application in the treatment of simple renal cysts due to its significant advantages such as short operation time, less trauma, quick recovery, safety, effectiveness, and low cost.
