INTRODUCTION Percutaneous nephrolithotomy (PCNL) is a standard, safe, and efficient method for removing large renal calculi. Despite development of endourologic equipment, complications of the PCNL are still prevalent. Even though therapeutic modalities such as mini-micro PCNL have been developed in recent years, the complications are a serious concern yet. The most important complication is he...

Acute blood loss in the postpartum period is the primary cause of maternal death worldwide [1] and postpartum hemorrhage complicates 4-6% of births [2]. In most cases of postpartum hemorrhage, bleeding from the genital tract is the source of the blood loss. Uterine atony accounts for 80% of postpartum hemorrhage [2] and genital tract injury, uterine inversion or rupture, genital tract or retrop...

INTRODUCTION Intraperitoneal and retroperitoneal hemorrhages may occur simultaneously in blunt abdominal trauma (BAT) patients. These patients undergo emergency laparotomies because of concomitant unstable hemodynamics and positive sonographic examination results. However, if the associated retroperitoneal hemorrhage is found intraoperatively and cannot be controlled surgically, then the patien...

 Bleeding is a common and potentially serious complication of acute and chronic renal failure.  Most common: bleeding at the site of fistula access puncture or temporary venous access insertion.  GI bleeding: is observed in up to 1/3 of uremic patients.  Other: subdural hematoma, spontaneous retroperitoneal bleeding, spontaneous subcapsular hematoma of the liver, intraocular hemorrhage, and...
