Abstract

PURPOSE: Evaluate the clinical superiority of using C-arm CT to establish percutaneous nephrolithotripsy (PCNL) accesses for patients with non-dilated renal collecting systems.

 

METHODS: From May 2014 to May 2015, 33 patients underwent C-arm CT guided puncture to establish PCNL accesses after ultrasound-guided nephrostomy attempts failure. The technical success, procedure details, patient radiation, complications and stone-free rate were recorded.

 

RESULTS: The technical success rate was 97.0% (32/33) with mean puncture scoreing 4.5/5. Mean puncture, dilation and fragmentation times were 17.9±6.0, 12.6±3.9 and 33.1±8.8 minutes, respectively. An exposure dose was 4.8±2.1 mSv without serious complications. Stone free rate was 93.8%.

 

 

CONCLUSIONS: C-arm CT is a useful tool to establish PCNL accesses especially in the cases of upper pole accesses or complicated anatomy.
