Abstract:
Objective To explore the techniques and efficacy of retroperitoneal laparoscopic operations in the treatment of renal cyst. Methods A total of 35 patients were operated on under general anesthesia. A water-filled balloon was used to dilate the retroperitoneal cavity. The renal cyst was exposed by identifying the psoas major muscle, peritoneal reflection, pillar of diaphragm and so on. All cyst walls were unroofed with ultrasonic scalpel 3～5 mm from the edge of renal parenchyma. Results With renal cysts removed, the operations were successfully accomplished in all the 35 patients. The operation time was 15～60 min (mean, 32 min). The intraoperative blood loss was 5～60 ml (mean, 35 ml). The postoperative hospital stay was 3～6 days. Pathological examinations reported benign lesions in 34 patients and suspected cystadenocarcinoma in 1 patient. All the 35 patients were followed for 1～22 months. No recurrence was found with exception of 1 case of remaining renal cyst 1.5 cm in diameter under B-ultrasonography at the first postoperative month. The patient with suspected adenocarcinoma had been followed for 1 year and no evidences of neoplasm or metastasis were detected on the chest roentgenogram and B-ultrasonography of the liver and the kidneys. Conclusions Retroperitoneal laparoscopic unroofing is a safe and effective procedure for renal cyst.
