Eur J Obstet Gynecol Reprod Biol 2024; 299:248-252.

Abstract
BACKGROUND The global prevalence of caesarean section as a delivery method is increasing worldwide. However, there is notable divergence among countries in their national guidelines regarding the optimal technique for blunt expansion hysterotomy of the low transverse uterine incision during caesarean section (cephalad-caudad or transverse). AIM To compare the risk of severe postpartum haemorrhage (PPH) between cephalad-caudad and transverse blunt expansion hysterotomy during caesarean section. METHODS This prospective comparative observational study was conducted in a university maternity hospital. All women who gave birth to one infant by caesarean section after 30 weeks of gestation between November 2020 and November 2021 were included in this study. The exclusion criteria were a coagulation disorder, the presence of placenta previa, multiple pregnancies, or enlargement of the hysterotomy with scissors. The choice between cephalad-caudad or transverse blunt expansion of the low transverse hysterotomy was left to the surgeon's discretion. The primary outcome measure was severe PPH, defined as estimated blood loss ≥ 1000 ml. Univariate and multivariate analyses were employed to assess the risk of severe PPH associated with the two methods of enlarging the low transverse hysterotomy. RESULTS The study included 850 women, of whom 404 underwent transverse blunt expansion and 446 underwent cephalad-caudad blunt expansion. The overall incidence of severe PPH was 13.3 %. Univariate analysis revealed no significant difference in the frequency of severe PPH between the cephalad-caudad and transverse blunt expansion groups (13.9 % vs 12.6 %; p = 0.61). However, the use of additional surgical sutures (mainly additional haemostatic stitches) was less common with cephalad-caudad blunt expansion (26.7 % vs 36.9 %; p < 0.05). Multivariate analysis showed no significant difference in risk between the two techniques (odds ratio 1.17, 95 % confidence interval 0.77-1.78). CONCLUSION No significant difference in the risk of severe PPH was found between cephalad-caudad and transverse blunt expansion of the low transverse hysterotomy during caesarean section.

Abstract
OBJECTIVE To identify procedures to reduce maternal morbidity during cesarean. MATERIAL AND METHODS The quality of evidence of the literature was assessed following the GRADE® method with questions formulated in the PICO format (Patients, Intervention, Comparison, Outcome) and outcomes defined a priori and classified according to their importance. An extensive bibliographic search was performed on PubMed, Cochrane and EMBASE databases. The quality of the evidence was assessed (high, moderate, low, very low) and a (i) strong or (ii) weak recommendations or (iii) no recommendation were formulated. The recommendations were reviewed in two rounds with external reviewers (Delphi survey) to select the consensus recommendations. RESULTS Of the 27 questions, there was agreement between the working group and the external reviewers on 26. The level of evidence of the literature was insufficient to provide a recommendation on 15 questions. Preventing hypothermia is recommended to increase maternal satisfaction and comfort (weak recommendation) and to reduce neonatal hypothermia (strong recommendation). The quality of the evidence of the literature did not allow to recommend the skin disinfectant to be used nor the relevance of a preoperative vaginal disinfection nor the choice between the use or nonuse of an indwelling bladder catheterization (if micturition takes place 1 hour before the cesarean section). The Misgav-Ladach technique or its analogues should be considered rather than the Pfannenstiel technique to reduce maternal morbidity (weak recommendation) bladder flap before uterine incision should not be performed routinely (weak recommendation), but a blunt (weak recommendation) and cephalad-caudad extension of uterine incision (weak recommendation) should be considered to reduce maternal morbidity. Antibiotic prophylaxis is recommended to reduce maternal infectious morbidity (strong recommendation) without recommendation on its type or the timing of administration (before incision or after cord clamping). The administration of carbetocin after cord clamping does not significantly decrease the incidence of blood loss>1000 ml, anemia, or blood transfusion compared with the administration of oxytocin. Thus, it is not recommended to use carbetocin rather than oxytocin in cesarean. It is recommended that systematic manual removal of the placenta not to be performed (weak recommendation). An antiemetic should be administered after cord clamping in women having a planned cesarean under locoregional anaesthesia to reduce intraoperative and postoperative nausea and vomiting (strong recommendation) with no recommendation regarding choice of use one or two antiemetics. The level of evidence of the literature was insufficient to provide any recommendation concerning single or double-layer closure of the uterine incision, or the uterine exteriorization. Closing the peritoneum (visceral or parietal) should not be considered (weak recommendation). The quality of the evidence of the literature was not sufficient to provide recommendation on systematic subcutaneous closure, including in obese or overweight patients, or the use of subcuticular suture in obese or overweight patients. The use of subcuticular suture in comparison with skin closure by staples was not considered as a recommendation due to the absence of a consensus in the external review rounds. CONCLUSION In case of cesarean, preventing hypothermia, administering antiemetic and antibiotic prophylaxis after cord clamping are the only strong recommendations. The Misgav-Ladach technique, the way of performing uterine incision (no systematic bladder flap, blunt cephalad-caudad extension), not performing routine manual removal of the placenta nor closure of the peritoneum are weak recommendations and may reduce maternal morbidity.

Abstract
INTRODUCTION AND HYPOTHESIS We aim to review iatrogenic bladder and ureteric injuries sustained during caesarean section and hysterectomy. METHODS A search of Cochrane, Embase, Medline and grey literature was performed using methods pre-published on PROSPERO. Eligible studies described iatrogenic bladder or ureter injury rates during caesarean section or hysterectomy. The 15 largest studies were included for each procedure sub-type and meta-analyses performed. The primary outcome was injury incidence. Secondary outcomes were risk factors and preventative measures. RESULTS Ninety-six eligible studies were identified, representing 1,741,894 women. Amongst women undergoing caesarean section, weighted pooled rates of bladder or ureteric injury per 100,000 procedures were 267 or 9 events respectively. Injury rates during hysterectomy varied by approach and pathological condition. Weighted pooled mean rates for bladder injury were 212-997 events per 100,000 procedures for all approaches (open, vaginal, laparoscopic, laparoscopically assisted vaginal and robot assisted) and all pathological conditions (benign, malignant, any), except for open peripartum hysterectomy (6,279 events) and laparoscopic hysterectomy for malignancy (1,553 events). Similarly, weighted pooled mean rates for ureteric injury were 9-577 events per 100,000 procedures for all hysterectomy approaches and pathologies, except for open peripartum hysterectomy (666 events) and laparoscopic hysterectomy for malignancy (814 events). Surgeon inexperience was the prime risk factor for injury, and improved anatomical knowledge the leading preventative strategy. CONCLUSIONS Caesarean section and most types of hysterectomy carry low rates of urological injury. Obstetricians and gynaecologists should counsel the patient for her individual risk of injury, prospectively establish risk factors and implement preventative strategies.

BMC Pregnancy Childbirth 2022; 22:541. [PMID: 35790950 PMCID: PMC9254569 DOI: 10.1186/s12884-022-04774-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Accepted: 05/20/2022] [Indexed: 11/23/2022] Open
Abstract
Background Genito-urinary fistulas may occur as complications of obstetric surgery. Location and circumstances can indicate iatrogenic origin as opposed to pressure necrosis following prolonged, obstructed labor. Methods This retrospective review focuses on 787 women with iatrogenic genito-urinary fistulas among 2942 women who developed fistulas after cesarean birth between 1994 and 2017. They are a subset of 5469 women who sought obstetric fistula repair between 1994 and 2017 in Tanzania, Uganda, Kenya, Malawi, Rwanda, Somalia, South Sudan, Zambia, and Ethiopia. We compared genito-urinary fistula classifications following vaginal birth to classifications following cesarean birth. We assessed whether and how the proportion of iatrogenic genito-urinary fistula was changing over time among women with fistula, comparing women with iatrogenic fistulas to women with fistulas attributable to pressure necrosis. We used mixed effects logistic regression to model the rise in iatrogenic fistula among births resulting in fistula and specifically among cesarean births resulting in fistula. Results Over one-quarter of women with fistula following cesarean birth (26.8%, 787/2942) had an injury caused by surgery rather than pressure necrosis due to prolonged, obstructed labor. Controlling for age, parity, and previous abdominal surgery, the odds of iatrogenic origin nearly doubled over time among all births resulting in fistula (aOR 1.94; 95% CI 1.48–2.54) and rose by 37% among cesarean births resulting in fistula (aOR 1.37; 95% CI 1.02–1.83). In Kenya and Rwanda the rise of iatrogenic injury outpaced the increasing frequency of cesarean birth. Conclusions Despite the strong association between obstetric fistula and prolonged, obstructed labor, more than a quarter of women with fistula after cesarean birth had injuries due to surgical complications rather than pressure necrosis. Risks of iatrogenic fistula during cesarean birth reinforce the importance of appropriate labor management and cesarean decision-making. Rising numbers of iatrogenic fistulas signal a quality crisis in emergency obstetric care. Unaddressed, the impact of this problem will grow as cesarean births become more common.

Abstract
Uterine niche is a potential significant consequence of Caesarean section and is diagnosed by ultrasound. The timing of Caesarean section (during pre, early or advanced labour), location of the incision (distance from the internal os), techniques for opening and closing the uterine cavity, and bladder flap have been frequently mentioned in the literature, however, these factors continue to be a source of disagreement with respect to whether they increase the risk of uterine niche or protect against this complication. In this review, we outline and discuss the possible risk factors that may be responsible for this entity. The main factor upon which obstetricians can act is the rate of first Caesarean section, which can and should be reduced. Moreover, a rather high incision at a distance from the internal os, and a sparing use of bladder detachment should be always kept in mind as well.

Abstract
Introduction This study designed to detect whether the routine haemoglobin (Hb) assay after uncomplicated caesarean section (CS) is necessary. Material and methods One hundred and twenty-two (122) women who delivered by uncomplicated elective CS were included in this observational study. Pre-operative investigations were performed according to the hospital protocol, including complete blood count, haemoglobin, prothrombin time, activated partial thromboplastin time, and liver and kidney function tests. After the uncomplicated elective CS, blood samples taken from participants immediately, 12, 24, 48 hours, and 1-week post-operative (PO) for haemoglobin assay. Student’s t-test was used to compare the pre-operative, and PO haemoglobins to detect whether or not the Hb assay after uncomplicated CSs is necessary. Results There was no significant difference between the pre-operative haemoglobin (11.6 ± 6.4 gms%), and the immediate PO haemoglobin (11.1 ± 5.9; p = 0.1 [95% CI: –1.05, 0.5, 2.05]) or 12-hour PO haemoglobin (10.9 ± 7.3; p = 0.9 [95% CI: –1.03, 0.7, 2.43]) or 24-hour PO haemoglobin (10.7 ± 8.2; p = 0.9 [95% CI: –0.95, 0.9, 2.75]). In addition, there was no significant difference between the pre-operative haemoglobin (11.6 ± 6.4 gms%), and 48-hour PO haemoglobin (11.2 ± 6.9; p = 0.7 [95% CI: –1.28, 0.4, 2.08]), or 1-week PO haemoglobin (11.4 ± 7.5; p = 0.9 [95% CI: –1.55, 0.2, 1.95]). Conclusions Routine PO haemoglobin assay after uncomplicated elective CSs is not necessary, especially when the pre-operative haemoglobin before the ECS ≥ 11 gms%, CS duration < 45 min, and estimated intra-operative blood loss ≤ 500 mL.

Abstract
The cesarean section is utilized to deliver babies since the late 19th century. Nowadays, the frequency of cesarean section is increased, mainly because of the low rate of complications and for the increasing demand from future mothers, scared by the idea of painful labor. Although the technique to perform cesarean section has been refined over time, infections, hemorrhage, pain and other consequences still represent matter of debate. To try to reduce the incidence of these complications many trials, randomized or not, have been performed, with the aim to analyze different technical aspects of this surgery. The aim of our review was to resume all the evidence-based instructions on how to best approach to cesarean section practice, in a step-to-step fashion, considering pre-operative actions, opening and closing steps, and postoperative prophylaxis.

Abstract
In present-day obstetrics, cesarean delivery occurs in one in three women in the United States, and in up to four of five women in some regions of the world. The history of cesarean section extends well over four centuries. Up until the end of the nineteenth century, the operation was avoided because of its high mortality rate. In 1926, the Munro Kerr low transverse uterine incision was introduced and became the standard method for the next 50 years. Since the 1970's, newer surgical techniques gradually became the most commonly used method today because of intraoperative and postpartum benefits. Concurrently, despite attempts to encourage vaginal birth after previous cesareans, the cesarean delivery rate increased steadily from 5 to 30-32% over the last 10 years, with a parallel increase in costs as well as short- and long-term maternal, neonatal and childhood complications. Attempts to reduce the rate of cesarean deliveries have been largely unsuccessful because of the perceived safety of the operation, short-term postpartum benefits, the legal climate and maternal request in the absence of indications. In the United States, as the cesarean delivery rate has increased, maternal mortality and morbidity have also risen steadily over the last three decades, disproportionately impacting black women as compared to other races. Extensive data on the prenatal diagnosis and management of cesarean-related abnormal placentation have improved outcomes of affected women. Fewer data are available however for the improvement of outcomes of cesarean-related gynecological conditions. In this review, the authors address the challenges and opportunities to research, educate and change health effects associated with cesarean delivery for all women.

Abstract
OBJECTIVE The objective of this study is to evaluate whether omission of intrauterine cleaning increases intraoperative and postoperative complications among women who deliver via cesarean section. METHODS We randomized 206 women undergoing primary elective cesarean deliveries to intrauterine cleaning or omission of cleaning. Postpartum endomyometritis rates across groups were the primary outcome. We also examined secondary outcomes. To detect a 20% difference in infection rate between the cleaned and the non-cleaned groups (two-tailed [alpha] = 0.05, [beta] = 0.2), 103 women were required per group. Analysis was by intention-to-treat. RESULTS Two hundred and six were randomized as follows: 103 to intrauterine cleaning and 103 to omission of cleaning after placental delivery. There were no statistically significant differences in the rate of endomyometritis between the two groups (2.0% versus 2.9%, RR =0.60; 95% CI 0.40-1.32). There were no statistically significant differences in postpartum hemorrhage rates (5.8% versus 7.7%, RR 0.75; 95% CI 0.6-1.2), hospital readmission rates (2.9 versus 3.8%, RR 0.75; 95% CI 0.5-1.6), time to return of gastrointestinal function, need for repeat surgery, or quantitated blood loss between the two groups. CONCLUSIONS Our randomized controlled trial provides evidence suggesting that omission of intrauterine cleaning during cesarean deliveries in women at low risk of infection does not increase intraoperative or postoperative complications.

Abstract
Caesarean section (CS) results in the occurrence of the phenomenon 'niche'. A 'niche' describes the presence of a hypoechoic area within the myometrium of the lower uterine segment, reflecting a discontinuation of the myometrium at the site of a previous CS. Using gel or saline instillation sonohysterography, a niche is identified in the scar in more than half of the women who had had a CS, most with the uterus closed in one single layer, without closure of the peritoneum. An incompletely healed scar is a long-term complication of the CS and is associated with more gynaecological symptoms than is commonly acknowledged. Approximately 30% of women with a niche report spotting at 6-12 months after their CS. Other reported symptoms in women with a niche are dysmenorrhoea, chronic pelvic pain and dyspareunia. Given the association between a niche and gynaecological symptoms, obstetric complications and potentially with subfertility, it is important to elucidate the aetiology of niche development after CS in order to develop preventive strategies. Based on current published data and our observations during sonographic, hysteroscopic and laparoscopic evaluations of niches we postulate some hypotheses on niche development. Possible factors that could play a role in niche development include a very low incision through cervical tissue, inadequate suturing technique during closure of the uterine scar, surgical interventions that increase adhesion formation or patient-related factors that impair wound healing or increase inflammation or adhesion formation.

Abstract
BACKGROUND Caesarean section (CS) is the most common obstetric surgical procedure, with more than one-third of pregnant women having lower-segment CS. Bladder evacuation is carried out as a preoperative procedure prior to CS. Emerging evidence suggests that omitting the use of urinary catheters during and after CS could reduce the associated increased risk of urinary tract infections (UTIs), catheter-associated pain/discomfort to the woman, and could lead to earlier ambulation and a shorter stay in hospital. OBJECTIVES To assess the effectiveness and safety of indwelling bladder catheterisation for intraoperative and postoperative care in women undergoing CS. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 December 2013) and reference lists of retrieved studies. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing indwelling bladder catheter versus no catheter or bladder drainage in women undergoing CS (planned or emergency), regardless of the type of anaesthesia used. Quasi-randomised trials, cluster-randomised trials were not eligible for inclusion. Studies presented as abstracts were eligible for inclusion providing there was sufficient information to assess the study design and outcomes. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for eligibility and trial quality, and extracted data. Data were checked for accuracy. MAIN RESULTS The search retrieved 16 studies (from 17 reports). Ten studies were excluded and one study is awaiting assessment. We included five studies involving 1065 women (1090 recruited). The five included studies were at moderate risk of bias.Data relating to one of our primary outcomes (UTI) was reported in four studies but did not meet our definition of UTI (as prespecified in our protocol). The included studies did not report on our other primary outcome - intraoperative bladder injury (this outcome was not prespecified in our protocol). Two secondary outcomes were not reported in the included studies: need for postoperative analgesia and women's satisfaction. The included studies did provide limited data relating to this review's secondary outcomes. Indwelling bladder catheter versus no catheter - three studies (840 women) Indwelling bladder catheterisation was associated with a reduced incidence of bladder distension (non-prespecified outcome) at the end of the operation (risk ratio (RR) 0.02, 95% confidence interval (CI) 0.00 to 0.35; one study, 420 women) and fewer cases of retention of urine (RR 0.06, 95% CI 0.01 to 0.47; two studies, 420 women) or need for catheterisation (RR 0.03, 95% CI 0.01 to 0.16; three studies 840 participants). In contrast, indwelling bladder catheterisation was associated with a longer time to first voiding (mean difference (MD) 16.81 hours, 95% CI 16.32 to 17.30; one study, 420 women) and more pain or discomfort due to catheterisation (and/or at first voiding) (average RR 10.47, 95% CI 4.71 to 23.25, two studies, 420 women) although high levels of heterogeneity were observed. Similarly, compared to women in the 'no catheter' group, indwelling bladder catheterisation was associated with a longer time to ambulation (MD 4.34 hours, 95% CI 1.37 to 7.31, three studies, 840 women) and a longer stay in hospital (MD 0.62 days, 95% CI 0.15 to 1.10, three studies, 840 women). However, high levels of heterogeneity were observed for these two outcomes and the results should be interpreted with caution.There was no difference in postpartum haemorrhage (PPH) due to uterine atony. There was also no difference in the incidence of UTI (as defined by trialists) between the indwelling bladder catheterisation and no catheterisation groups (two studies, 570 women). However, high levels of heterogeneity were observed for this non-prespecified outcome and results should be considered in this context. Indwelling bladder catheter versus bladder drainage - two studies (225 women)Two studies (225 women) compared the use of an indwelling bladder catheter versus bladder drainage. There was no difference between groups in terms of retention of urine following CS, length of hospital stay or the non-prespecified outcome of UTI (as defined by the trialist).There is some evidence (from one small study involving 50 women), that the need for catheterisation was reduced in the group of women with an indwelling bladder catheter (RR 0.04, 95% CI 0.00 to 0.70) compared to women in the bladder drainage group. Evidence from another small study (involving 175 women) suggests that women who had an indwelling bladder catheter had a longer time to ambulation (MD 0.90, 95% CI 0.25 to 1.55) compared to women who received bladder drainage. AUTHORS' CONCLUSIONS This review includes limited evidence from five RCTs of moderate quality. The review's primary outcomes (bladder injury during operation and UTI), were either not reported or reported in a way not suitable for our analysis. The evidence in this review is based on some secondary outcomes, with heterogeneity present in some of the analyses. There is insufficient evidence to assess the routine use of indwelling bladder catheters in women undergoing CS. There is a need for more rigorous RCTs, with adequate sample sizes, standardised criteria for the diagnosis of UTI and other common outcomes.

Abstract
OBJECTIVE We sought to test the hypothesis that an extraperitoneal cesarean section (ECS) technique reduces postoperative pain without increasing intraoperative and postoperative complications. STUDY DESIGN In a single-center, single-blinded prospective trial we randomized 54 patients with an indication for primary or first repeat cesarean section at term pregnancy to an ECS (n = 27) or transperitoneal cesarean section (TCS) (n = 27) procedure. Patients with suspected abnormal placentation, a history of >1 cesarean section, or major abdominal surgery were excluded. The primary endpoint of the study was maximum abdominal pain measured by numeric rating scale ranging from 0-10. RESULTS Patients after ECS had significantly less maximum surgical site pain than patients after TCS. Median peak pain scores on postoperative day 1 were 4.00 (interquartile range, 3.00-5.00) for ECS and 5.00 (interquartile range, 4.00-7.00) for TCS, respectively (P = .031). Analgesic requirements, intraoperative nausea, and postoperative shoulder pain were significantly less after ECS. Overall operative time was significantly shorter in ECS, with no difference in delivery time. No bladder injury occurred in either group. There were no differences in estimated blood loss and neonatal outcome. Urogenital distress, urinary tract infection, and bowel dysfunction did not differ at discharge from hospital and 6 weeks after. CONCLUSION An extraperitoneal approach to cesarean section appears to reduce postoperative pain, usage of analgesics, and intraoperative nausea without an increase in significant complications.

Abstract
Cesarean section is the most common surgery performed in the United States with over 30% of deliveries occurring via this route. This number is likely to increase given decreasing rates of vaginal birth after cesarean section (VBAC) and primary cesarean delivery on maternal request, which carries the inherent risk for intraoperative complications. Urologic injury is the most common injury at the time of either obstetric or gynecologic surgery, with the bladder being the most frequent organ damaged. Risk factors for bladder injury during cesarean section include previous cesarean delivery, adhesions, emergent cesarean delivery, and cesarean section performed at the time of the second stage of labor. Fortunately, most bladder injuries are recognized at the time of surgery, which is important, as quick recognition and repair are associated with a significant reduction in patient mortality. Although cesarean delivery is a cornerstone of obstetrics, there is a paucity of data in the literature either supporting or refuting specific techniques that are performed today. There is evidence to support double-layer closure of the hysterotomy, the routine use of adhesive barriers, and performing a Pfannenstiel skin incision versus a vertical midline subumbilical incision to decrease the risk for bladder injury during cesarean section. There is also no evidence that supports the creation of a bladder flap, although routinely performed during cesarean section, as a method to reduce the risk of bladder injury. Finally, more research is needed to determine if indwelling catheterization, exteriorization of the uterus, and methods to extend hysterotomy incision lead to bladder injury.
