title: Safety and efficacy of intravesical aminocaproic acid for bleeding after transurethral resection of prostate.
abstract: There appears to be no clinically significant difference in blood loss or transfusion requirements after transurethral resection of the prostate (TURP) when intravesical 0.5% aminocaproic acid is compared with 0.9% sodium chloride irrigation in patients during the first three days after surgery. This is probably because early post-TURP bleeding is due to inadequate hemostasis or perforation of the prostatic capsule, and not excessive local or systemic fibrinolysis. However, we suggest that intravesical aminocaproic acid might be a useful alternative to systemic antifibrinolytic therapy in patients with delayed, recurrent, excessive post-prostatectomy bleeding, which is thought to be due to fibrinolysis. Since aminocaproic acid is not systemically absorbed after bladder instillation, intravesical administration causes few side effects and does not necessitate screening patients for disseminated intravascular coagulation prior to treatment.
