ABSTRACT
UNLABELLED OBJECTIVE.The aim of this study was to report the authors' experience with percutaneous intrarenal marsupialization of symptomatic peripelvic renal cysts. MATERIAL AND METHODS:
Thirty-one patients (16 male and 15 female, with a mean age of 49 years) with a peripelvic renal cyst associated with chronic flank or lumbar pain or urinary infection were selected for percutaneous intrarenal marsupialization with a 2 µm laser in the authors' centre from January 2005 to December 2010. Cyst size ranged from 4.5 to 10.5 (mean 6.0) cm. The cysts were punctured by a percutaneous technique guided by ultrasonography, a 20.8 F nephroscope was introduced and the whole internal surface of the cyst was inspected. Methylene blue was injected through the ureteral catheter to help identify the collecting system. A 1.5-4 cm incision was made at the avascular area of the cystic wall by the 2 µm laser to achieve intrarenal marsupialization of the cyst into the renal collecting system. One or two 6 F double-J stents were placed with the proximal end in the cyst for 2-3 months.RESULTS:
The mean operation time was 50 (25-120) min. No serious complications such as massive bleeding, urine leak or infected haematoma occurred. The patients were followed up for a mean of 12 (range 3-36) months. All patients were relieved of their symptoms. Eighteen cysts disappeared after surgery, while 13 cysts reduced in size by over one-third and communicated with the renal collecting system. No enlargement of cysts was observed.CONCLUSIONS:
Percutaneous intrarenal marsupialization with a 2 µm laser is an effective and safe procedure and may offer a minimally invasive alternative for the management of symptomatic peripelvic renal cysts.
