We compared single- and double-stick techniques of percutaneous nephrostomy insertion by retrospectively reviewing 140 percutaneous nephrostomy procedures in 101 patients. All procedures were performed by residents or fellows with direct attending supervision. Either the single-stick or double-stick technique was used based solely on personal attending preference. There were no significant differences in groups in terms of age, sex, or degree of hydronephrosis. In the single-stick technique, the kidney was punctured with sonographic guidance and the tract was serially dilated to accept an 8.5 Fr. nephrostomy catheter. In the double-stick technique, the kidney was punctured with sonographic guidance and a mixture of air and contrast were injected into the collecting system. The affected side was then elevated and a posterior calyx was punctured using fluoroscopic guidance. Both groups were compared in terms of complications and early tube dysfunction using the chi-squared test. All procedures were successful without immediate complications. Bleeding requiring transfusion occurred in 4.7% (4/86) procedures in the single stick group and 3.7% (2/54) in the double stick group (p-value not significant). None of these patients required further interventions for bleeding. Tube dysfunction leading to premature tube exchange occurred in 3.5% (3/86) of catheters in the single stick group and 3.7% (2/54) of catheters in the double- stick group (p-value not significant). We found no significant difference between the single and double- stick methods of percutaneous nephrostomy in terms of success rates, complications, or tube function. We believe that the single-stick method should be adopted as the insertion technique of choice.
