[Laparoscopic resection of a simple renal cyst].

Laparoscopic dissection of common renal cysts was made in 27 patients who complained of low back pains and hypertension. The diagnosis and indications for operation rested on ultrasonic investigation and dynamic nephroscintigraphy. All the surgical interventions were performed under endotracheal anesthesia after creation of pneumoperitoneum with the use of three trochars. The procedure comprised maximal dissection of the free cystic wall, electrocoagulation of the residual part's margins and retroperitoneal drainage. Postoperative period was uneventful in 92.6% of the cases. Control examination 3 and 6 months after the operation indicated good results: pain relief, stabilization of arterial pressure and improvement of renal function.
