| Popis: | Objectives: To investigate the safety, efficacy, and practicability of minimally invasive percutaneous nephrolithotomy (MPCNL) with the aid of a patented irrigation clearance system in treating renal staghorn calculi. Methods: From August 2009 to July 2014, 4 hospitals had executed a prospective multicenter study with a total of 912 cases. The patients were randomly divided into 3 groups: suctioning MPCNL, standard percutaneous nephrolithotomy (PCNL), and traditional MPCNL groups. Multiple operative and perioperative parameters were compared. Results: Blood loss and intrapelvic pressure in the suctioning MPCNL group were significantly less than those in the standard PCNL group. The average operation time, intrapelvic pressure, and amount of bleeding in the suctioning MPCNL group were better than those in the traditional MPCNL group. The suctioning MPCNL used one tract more frequently and 2 or 3 tracts less frequently than the standard MPCNL and traditional MPCNL groups. The stone-free rate by one surgery in the suctioning MPCNL group was significantly higher than that in standard PCNL and traditional MPNCL groups. Conclusions: Suctioning MPCNL using our patented system shows several advantages in treating renal staghorn calculi, including minimal invasion, shorter operation time, lower intrapelvic pressure, less bleeding and the need for a smaller number of percutaneous tracts, and higher stone clearance rate by one surgery. |
