title: Tubeless percutaneous nephrolithotomy with non-absorbable hemostatic sealant (Quikclot®) versus nephrostomy tube placement: a propensity score-matched analysis.
abstract: The purpose of this study was to determine the efficacy and safety of tubeless percutaneous nephrolithotomy (PNL) using a non-absorbable hemostatic sealant (Quikclot(®)) as an adjunct compared to nephrostomy tube placement in patients exhibiting significant parenchymal bleeding following PNL. We identified 113 PNL cases performed between May 2011 and October 2014. For patients with insignificant parenchymal bleeding following stone removal, defined as a clear visualization of the surgical field at full irrigation of the nephroscope, tubeless PNL was performed. For patients with significant parenchymal bleeding, we introduced the tubeless Quikclot(®) technique as of September 2013 and have performed it ever since. Formerly, nephrostomy placement PNL was performed. In this study, 40 Quikclot(®) applied PNL cases were matched with an equal number of nephrostomy placement cases by propensity scoring based on body mass index, stone size, and Guy's stone score. The mean postoperative drop in hematocrit was comparative between the Quikclot(®) group and the nephrostomy group on both postoperative days 1 (p = 0.459) and 2 (p = 0.325). Quikclot(®) application was associated with lower VAS scores throughout the postoperative period, lower cumulative analgesic requirement (p = 0.025), and with shorter hospitalization (p = 0.002). Complication rates were comparable with no need for blood transfusions in any patients. Tubeless Quikclot(®) PNL was safe and provided effective hemostasis of significant parenchymal bleeding. By avoiding nephrostomy placement, we were able to reduce postoperative pain, analgesic requirements, and hospitalization. Application of Quikclot(®) may be considered prior to nephrostomy placement in patients with significant parenchymal bleeding.
