Urinary tract injuries during cesarean delivery: long-term outcome and management.

Urinary tract injury during cesarean delivery is a rare but severe complication. Due to the high prevalence of cesarean delivery, this injury may pose a high burden of morbidity. We reviewed the cases of lower urinary tract injuries identified during cesarean delivery in a tertiary medical center and identified diagnosis and treatment methods, as well as short and long-term outcomes, to establish a protocol of care for such cases. We included women with urinary tract injury during cesarean delivery between 2004 and 2018. The cases were identified according to ICD-9 codes, as well as free text in the medical report and discharge letter. Data were collected retrospectively. Telephone interviews were conducted to obtain additional data regarding long-term outcomes. In14 years, a total of 17,794 cesarean deliveries were performed at our institution (17.5% of all deliveries), 14 cases of bladder injury, and 11 cases of ureteral injury were identified featuring an incidence of 0.08 and 0.06%, respectively. All bladder injuries were diagnosed and repaired intra-operatively. Six (55%) cases of ureteral injury were diagnosed in the post-operative period, and 3 of these patients required further surgery for definitive treatment. None of the patients suffered long-term adverse effects. Most bladder injuries occurred in women with previous cesarean delivery in the presence of abdominal adhesions. In contrast, most ureteral injuries occurred in women with emergency cesarean delivery during the second stage of labor, and were accompanied by an extension of the uterine incision. All women had normal kidney function in follow up and did not suffer from long term sequelae. Urinary tract injury is an uncommon complication of cesarean delivery. A high index of suspicion is recommended to avoid late diagnosis and complications. We propose a comprehensive protocol for the management of these injuries. [ABSTRACT FROM AUTHOR]
