The purpose of the study was to systematically review and assess the safety and efficacy of hemostatic agents in tubeless percutaneous nephrolithotomy. Original studies on the use of hemostatic agents in tubeless percutaneous nephrolithotomy (PCNL) from January 2001 to March 2014 were searched in Ovid, Science Direct, Pubmed, and Embase by two independent reviewers. A drop in hemoglobin (Hb), analgesic
requirements, length of hospital stay, and necessity for blood transfusions were compared using Review Manager 5.2. The methods were done according to the Cochrane Handbook for interventional systematic reviews and written based on the PRISMA Statement. Seven studies involving 351 patients met the inclusion criteria for the meta-analysis. The baseline characteristics were comparable in all of the studies. The results showed that the length of hospital stay was less in the experimental group than in the control group (P < 0.05). There were no significant statistical differences in terms of a drop in Hb, analgesic requirements, and the necessity for a blood transfusion between the two groups (P > 0.05). The meta-analysis indicated that the hemostatic agents in tubeless PCNL were not expected to be unsafe or mandatory, but that they were expected to be expensive. We concluded that hemostatic agents might not be necessary in tubeless PCNL.
