Tubeless percutaneous nephrolithotomy: Can be a choice, why not?

Abstract

Percutaneous nephrolithotomy (PCNL) has been widely accepted and is commonly used to treat renal calculi. The optimal drainage of kidney after PCNL has not been clearly determined yet. Placement of an 18F to 24F nephrostomy tube at the end of the procedure is accepted as standard of care to date. The main advantages are adequate renal drainage, hemostatic tamponade and providing renal access for second look PCNL. However, based on the concept that the purpose of the tube is only to maintain adequate drainage of the kidney, a "tubeless" approach has been developed by placing a ureteral stent or catheter to provide drainage after PCNL instead of a nephrostomy tube. Tubeless PCNL is an effective and safe procedure for treatment of renal stones in selected cases. This procedure can even be chosen for patients with previous renal surgery, and hemorrhagic tendency. By using this method, less postoperative pain and a shorter hospital stay can be achieved, when compared with conventional PCNL. There is a controversy over ideal drainage system after PCNL in recent years. Herein, we made a systematic review for efficacy and safety of tubeless PCNL, totally tubeless PCNL, discussed different variations and compared the outcomes of this technique with standart PCNL. © Karadag et al.; Licensee Bentham Open.
