BACKGROUND: Obstetric hemorrhage is an urgent problem of global health care, since it occupies a leading position in the structure of maternal mortality. AIM: The aim of this study was to analyze data on hemostasis in obstetric bleeding. MATERIALS AND METHODS: The article presents a review of the world literature on modern approaches to hemostasis, which take into account new data on the anatomical structure of the female reproductive system. RESULTS AND CONCLUSIONS: Based on the foreign and domestic literature data, a strict step-by-step implementation of all prescribed measures along with a differentiated approach to treatment that takes into account anatomical features is the key to success in the fight against obstetric bleeding as the main cause of maternal mortality in the world.

Urinary tract injury is a rare but severe complication during abdominal delivery. Over the past quarter of the last century, the frequency of abdominal delivery in Russia has more than tripled due to the increase in the number of pregnant women at high risk for the development of maternal and perinatal complications. Intraoperative diagnosis of urinary tract injuries allows timely treatment with better postoperative outcomes. Given the high percentage of caesarean sections in many countries, the risk of the above complications remains high. Risk factors for urinary tract injury during cesarean section are an increase in womens average age and body mass index, high parity, the presence of adhesions, prior cesarean section, emergency cesarean section, and cesarean section in the second stage of labor. This article discusses several clinical cases on the development of urological complications in obstetrics and gynecology. Due to modern progress in the field of operative obstetrics, vesicouterine fistulas caused by obstetric causes may not occur as often as in the last century. Nevertheless, even despite this, one should not forget about elementary preventive measures in operative delivery, especially in such obstetric situations as placental ingrowth, bleeding, hematoma, and parametria.
