Surgical outcomes of retroperitoneal laparoscopic renal cyst decortication at Nghe An Friendship General Hospital

Tóm tắt

Objective: To describe the clinical and paraclinical characteristics and evaluate the surgical outcomes of retroperitoneal laparoscopic renal cyst decortication. Subjects and Methods: A prospective cross-sectional descriptive study was conducted on patients with a confirmed diagnosis who underwent retroperitoneoscopic renal cyst excision at Nghe An Friendship General Hospital from January 2025 to December 2025. Results: A total of 64 patients were included, with a mean age of 57.3 ± 14.7 years (range: 19–76), with a female-to-male ratio of 1.1:1. A total of 43/64 patients (67.1%) had a history of chronic medical conditions, and 4/64 patients (6.7%) had previously undergone urological surgery. Flank pain was the most common presenting symptom, reported in 84.4% of the patients. Imaging findings showed that the mean cyst diameter measured by computed tomography (CT) and ultrasonography was 78.6 ± 25.9 mm (58–121 mm) and 80.4 ± 26.1 mm (60–126 mm), respectively. The proportion of cysts measuring 50–100 mm was 76.6% on CT and 79.7% on ultrasound, while thin-walled cysts accounted for 90.6% and 93.7% on CT and ultrasound, respectively. The mean operative time was 54.5 ± 10.8 min (range: 25–73 min), and no intraoperative complications were recorded. Postoperative complications included bleeding through the drainage tube in two patients (3.1%). The mean length of hospital stay was 3.08 ± 0.74 days (range, 2–5 days). At the 1-month postoperative follow-up, 7.8% of the patients still experienced flank pain, and 3.1% had residual renal cysts detected on ultrasonography. Conclusion: Retroperitoneal laparoscopic renal cyst decortication is a safe and effective surgical method for treating renal cysts.
