Abstract
We aimed to investigate the safety and efficacy of tubeless percutaneous nephrolithotomy (PCNL) with ureteral catheter or double-J stent in comparison with standard PCNL in our study. We retrospectively evaluated 707 of 1,469 patients with stone area under 800 mm(2) and only one subcostal nephrostomy access that was underwent PCNL between March 2004 and October 2011 in our clinic. Patients with 14F nephrostomy tube (Malecot or Re-entry catheter), with ureteral stent and with antegrade double-J stent were included into Group 1 (n = 180), Group 2 (n = 148) and Group 3 (n = 120), respectively. The mean hospitalization time of patients in Group 1 was significantly longer. The mean VAS was significantly higher in Group 1. On the other hand the mean fluoroscopy and operation time of patients in Group 2 were significantly shorter in comparison with other groups. Number of patients with postoperative transfusion requirement was significantly higher in Group 1. The number of patients with postoperative narcotic analgesic requirement was also significantly higher in Group 1. The most frequent complication in our study was prolonged drainage. The postoperative complications were seen more frequently in Group 1. Both ureter catheter and double j stent were more comfortable, effective and safe in urinary drainage following PCNL with single sub-costal access. On the other hand, double-J stent has a disadvantage as requirement additional cystoscopy for removal. We suggest ureter catheter or double-J stent to preserve short- and long-term urinary drainage.
