Review
A Cesarean Scar Pregnancy (CSP) is a variant of uterine ectopic pregnancy defined by full or partial implantation of the gestational sac in the scar of a previous cesarean section. The continuous increase of Cesarean Deliveries is causing a parallel increase in CSP and its complications. Considering its high morbidity, the most usual recommendation has been termination of pregnancy in the first trimester; however, several cases progress to viable births. The aim of this systematic review is to evaluate the outcome of CSP managed expectantly and understand whether sonographic signs could correlate to the outcomes. An online-based search of PubMed and Cochrane Library Databases was used to gather studies including women diagnosed with a CSP who were managed expectantly. The description of all cases was analysed by the authors in order to obtain information for each outcome. 47 studies of different types were retrieved, and the gestational outcome was available in 194 patients. Out of these, 39 patients (20,1%) had a miscarriage and 16 (8,3%) suffered foetal death. 50 patients (25,8%) had a term delivery and 81 (41,8%) patients had a preterm birth, out of which 27 (13,9%) delivered before 34 weeks of gestation. In 102 (52,6%) patients, a hysterectomy was performed. Placenta Accreta Spectrum (PAS) was a common disorder among CSP and was linked to a higher rate of complications such as foetal death, preterm birth, hysterectomy, haemorrhagic morbidity and surgical complications. Some of the analysed articles showed that sonographic signs with specific characteristics, such as type II and III CSP classification, Crossover Sign - 1, "In the niche" implantation and lower myometrial thickness could be related to worse outcomes of CSP. This article provides a good understanding of CSP as an entity that, although rare, presents with a high rate of relevant morbidity. It is also understood that pregnancies with confirmed PAS had an even higher rate of morbidity. Some sonographic signs were shown to predict the prognosis of these pregnancies and further investigation is necessary to validate one or more signs so they can be used for a more reliable counselling of women with CSP.

BACKGROUND
Transvaginal ultrasound imaging has become an essential tool in the prenatal evaluation of the lower uterine segment and anatomy of the cervix, but there are only limited data on the role of transvaginal ultrasound in the management of patients at high risk of placenta accreta spectrum at birth.
OBJECTIVE
This study aimed to evaluate the role of transvaginal sonography in the third trimester of pregnancy in predicting outcomes in patients with a high probability of placenta accreta spectrum at birth.
STUDY DESIGN
This was a retrospective analysis of prospectively collected data of patients presenting with a singleton pregnancy and a history of at least 1 previous cesarean delivery and patients diagnosed prenatally with an anterior low-lying placenta or placenta previa delivered electively after 32 weeks of gestation. All patients had a least 1 detailed ultrasound examination, including transabdominal and transvaginal scans, within 2 weeks before delivery. Of note, 2 experienced operators, blinded to the clinical data, were asked to make a judgment on the likelihood of placenta accreta spectrum as a binary, low or high-probability of placenta accreta spectrum, and to predict the main surgical outcome (conservative vs peripartum hysterectomy). The diagnosis of accreta placentation was confirmed when one or more placental cotyledons could not be digitally separated from the uterine wall at delivery or during the gross examination of the hysterectomy or partial myometrial resection specimens.
RESULTS
A total of 111 patients were included in the study. Abnormal placental tissue attachment was found in 76 patients (68.5%) at birth, and histologic examination confirmed superficial villous attachment (creta) and deep villous attachment (increta) in 11 and 65 cases, respectively. Of note, 72 patients (64.9%) had a peripartum hysterectomy, including 13 cases with no evidence of placenta accreta spectrum at birth because of failure to reconstruct the lower uterine segment and/or excessive bleeding. There was a significant difference in the distribution of placental location (X=12.66; P=.002) between transabdominal and transvaginal ultrasound examinations, but both ultrasound techniques had similar likelihood scores in identifying accreta placentation that was confirmed at birth. On transabdominal scan, only a high lacuna score was significantly associated (P=.02) with an increased chance of hysterectomy, whereas on transvaginal scan, significant associations were found between the need for hysterectomy and the thickness of the distal part of the lower uterine segment (P=.003), changes in the cervix structure (P=.01), cervix increased vascularity (P=.001), and the presence of placental lacunae (P=.005). The odds ratio for peripartum hysterectomy were 5.01 (95% confidence interval, 1.25-20.1) for a very thin (<1-mm) distal lower uterine segment and 5.62 (95% confidence interval, 1.41-22.5) for a lacuna score of 3+.
CONCLUSION
Transvaginal ultrasound examination contributes to both prenatal management and the prediction of surgical outcomes in patients with a history of previous cesarean delivery with and without ultrasound signs suggestive of placenta accreta spectrum. Transvaginal ultrasound examination of the lower uterine segment and cervix should be included in clinical protocols for the preoperative evaluation of patients at risk of complex cesarean delivery.

Review
Endometrial cancer is the fifth most common female cancer worldwide and the third leading female cancer in the Western world. The marked surge in endometrial cancer incidence is alarming. The aim of the present review is to focus on endometrial cancer affecting young women of reproductive age. Surgery, namely abdominal or laparoscopic hysterectomy, with or without salpingo-oophorectomy, and sentinel lymph node detection has become the standard surgical strategy for early stage endometrioid endometrial cancer. However, premenopausal women might want to preserve their fertility, especially if they are nulliparous or have not reached their desired number of children at the time of diagnosis. Conservative, uterus-sparing treatment, based on progestin products, may be an advantageous option for patients meeting the necessary criteria. Potential candidates have to be committed to following a rigorous protocol of treatment, investigations and follow-up. The evidence in favor of this approach, although limited, is encouraging and patients who have achieved a histologically documented disease complete remission could attempt to conceive spontaneously or with the immediate use of assisted reproductive technology techniques. The risk of partial or negative response to progestin treatment or cancer recurrence is well documented, thus patients have to be aware of the possible need for interruption of conservative treatment and hysterectomy.

BACKGROUND
Uterine artery embolization (UAE) has been used to treat symptomatic uterine leiomyomas since 1995. This case report describes a rare complication of UAE, with delayed recognition, ultimately requiring definitive hysterectomy.
CASE
A 53-year-old women with symptomatic leiomyomas underwent imaging demonstrating an enlarged (16.9×11.3×11.5 cm) uterus with multiple leiomyomas. She underwent UAE and, over the subsequent 3 months, and had five emergency department visits for abdominal pain and dysuria. Pelvic magnetic resonance imaging (MRI) 4 months postprocedure showed nodular mural enhancement of the right anterior bladder dome, and cystoscopy demonstrated irregular tissue on the right dome of the bladder. The patient ultimately underwent total laparoscopic hysterectomy, bilateral salpingo-oophorectomy, partial cystectomy with reconstruction, and omental flap for bladder necrosis and leiomyoma fistulization.
CONCLUSION
Bladder necrosis and leiomyoma fistulization are rare complications of UAE that can present with pelvic pain, hematuria, and recurrent bladder stones. Computed tomography and MRI can be useful tools in evaluating for complications, but clinicians should have a low threshold to use cystoscopy to directly visualize potential abnormalities identified on imaging. Patients with complex cases with suspected post-UAE complications warrant referral to tertiary care centers for a multidisciplinary approach.

Ultrasound in Obstetrics & Gynecology :... Aug 2023To describe the clinical and sonographic characteristics of intramural pregnancy, as well as the available management options and treatment outcomes.
OBJECTIVE
To describe the clinical and sonographic characteristics of intramural pregnancy, as well as the available management options and treatment outcomes.
METHODS
This was a retrospective single-center study of consecutive patients with a sonographic diagnosis of intramural pregnancy between November 2008 and November 2022. An intramural pregnancy was diagnosed on ultrasound when a pregnancy was implanted within the uterine corpus, above the level of the internal cervical os and separate from the interstitial section of the Fallopian tube, and extended beyond the decidual-myometrial junction. Clinical, ultrasound, relevant surgical and histological information and outcomes were retrieved from each patient's record and analyzed.
RESULTS
Eighteen patients were diagnosed with an intramural pregnancy during the study period. Their median age was 35 (range, 28-43) years and the median gestational age at diagnosis was 8 + 1 (range, 5 + 5 to 12 + 0) weeks. Vaginal bleeding with or without abdominal pain was the most common presenting symptom, recorded in eight patients. Nine (50%) patients had a partial and nine (50%) had a complete intramural pregnancy. Embryonic cardiac activity was present in eight (44%) pregnancies. The majority of pregnancies (n = 10 (56%)) were initially managed conservatively, including expectant management in eight (44%) cases, local injection of methotrexate in one (6%) and embryocide in one (6%). Conservative management was successful in nine of the 10 (90%) pregnancies, with a median time to serum human chorionic gonadotropin resolution of 71 (range, 35-143) days. One patient with an ongoing live pregnancy had an emergency hysterectomy for a major vaginal bleed at 20 weeks' gestation. No other patient managed conservatively experienced any significant complication. The remaining eight (44%) patients had primary surgical treatment, comprising transcervical suction curettage in seven (88%) of these cases, while one patient presented with uterine rupture and underwent emergency laparoscopy and repair.
CONCLUSIONS
We describe the ultrasound features of partial and complete intramural pregnancy, demonstrating key diagnostic features. Our series suggests that, when intramural pregnancy is diagnosed before 12 weeks' gestation, it can be managed either conservatively or by surgery, with preservation of reproductive function in most women. © 2023 The Authors.

BACKGROUND
Endometriosis is a chronic, debilitating condition affecting up to 10% of reproductive-age women. Urinary tract endometriosis is found in 1%-6% of women diagnosed with pelvic endometriosis, with the most common sites being the bladder (70%-85%), ureter (9%-23%), and kidney (4%). Patients typically present with symptoms such as lower abdominal pain, dysuria, and urgency. Unfortunately, urinary tract endometriosis is often asymptomatic, potentially leading to silent obstructive uropathy and kidney failure.
OBJECTIVE
To demonstrate a step-by-step approach for the surgical management of urinary tract endometriosis using conventional laparoscopy for partial cystectomy and robotic-assisted laparoscopy for ureteroneocystostomy.
MATERIAL AND METHOD
Surgical video of 2 cases managed in an academic tertiary referral center for endometriosis. The first case was a 38-year-old Gravida 3, Para 3 with a history of hysterectomy who had an MRI which revealed a T2 hypointense bladder nodule consistent with endometriosis. Patient had significant urinary urgency, dysuria, and suprapubpic pain that improved but did not disappear after starting oral progestin therapy (5 mg of norethindrone). A cystoscopy was first performed to confirm MRI findings of bladder lesion and to delineate borders and depth of invasion. The second case was a 35-year-old nulliparous woman with chronic pelvic pain and primary infertility. The patient had a history of stage IV endometriosis with deep endometriosis into the bowel and extrinsic encasement of the ureters causing subsequent hydronephrosis requiring bilateral ureteral stents. She had continued daily pelvic pain despite of being on oral contraceptives for medical management of endometriosis. She subsequently underwent bilateral percutaneous nephrostomy tube placement to allow for ureteral rest prior to surgery.
RESULTS
In the first case, conventional laparoscopy was utilized to perform bilateral ureterolysis, bladder mobilization, partial cystectomy for complete excision of the lesion, and 2-layered bladder closure. Use of indigo carmine assisted with ureteral orifice identification. In the second case, a cystoscopy was performed with injection of Indocyanine green to assist with ureteral identification. After ureterolysis, distal ureteric obstruction due to extensive disease was confirmed on laparoscopy and ureteroscopy. Bilateral ureteroneocystostomy with placement of Double-J ureteral stents was performed using a robotic-assisted approach. Each patient had an indwelling Foley catheter for bladder decompression during recovery. Pathology in both cases revealed endometriosis. Both patients had an uneventful postoperative course. A postoperative retrograde cystogram confirmed adequate repair prior to removal of each Foley catheter. Patient 2 had uncomplicated office stent removal 6 weeks postoperatively and had a normal renal ultrasound with no hydronephrosis 6 months postoperatively.
CONCLUSION
Endometriosis is an increasingly common condition. It is important for gynecological surgeons to have the proper understanding of anatomy, surgical technique, and multidisciplinary care needed with urology for safe and complete excision of bladder and ureter endometriosis.

BACKGROUND
Angiosarcoma (AS) is a rare and highly aggressive soft tissue disease that most commonly arises in deep soft tissues. There are only a few reported cases of AS involving the ovary and even fewer reports of the underlying molecular abnormalities. Here, we briefly review two cases of primary ovarian AS (oAS) with specific molecular events and immune checkpoints. The clinical features and prognosis of the disease, diagnosis, differential diagnosis, and new treatment approaches are discussed based on a literature review.
CASE SUMMARY
Case 1: A 51-year-old female patient was admitted with right lower limb pain for 5 mo, and lower abdominal pain with hematuria for 1 mo. Partial removal of rectus abdominis muscle and fascia, partial hysterectomy, bilateral salpingo-oophorectomy, and inguinal and pelvic lymphadenectomy were performed. Pathology revealed primary oAS. Fluorescence hybridization revealed gene amplification. MESNA + ADM + IFO + DTIC (MAID) regimen was administered, but stable disease was achieved. The patient died 1 mo later. Case 2: A 41-year-old female patient presented with fatigue, nausea, decreased appetite, and diffuse abdominal pain. On physical examination, the abdomen was distended and a complex cystic mass was palpable in the right pelvic cavity. Pathology revealed primary oAS. MAID chemotherapy was administered and programmed death ligand 1 (PD-L1) staining was performed on the tumor samples. The patient benefited from anti-PD-1 immunotherapy and is alive without any evidence of disease 27 mo off therapy in follow-up.
CONCLUSION
Long-term survival benefit for primary oAS can be achieved by alternative therapeutic strategies using pathological indicators to inform treatment.

Risk prediction models for cancer stage at diagnosis may identify individuals at higher risk of late-stage cancer diagnoses. Partial proportional odds risk prediction models for cancer stage at diagnosis for males and females were developed using data from Alberta's Tomorrow Project (ATP). Prediction models were validated on the British Columbia Generations Project (BCGP) cohort using discrimination and calibration measures. Among ATP males, older age at diagnosis was associated with an earlier stage at diagnosis, while full- or part-time employment, prostate-specific antigen testing, and former/current smoking were associated with a later stage at diagnosis. Among ATP females, mammogram and sigmoidoscopy or colonoscopy were associated with an earlier stage at diagnosis, while older age at diagnosis, number of pregnancies, and hysterectomy were associated with a later stage at diagnosis. On external validation, discrimination results were poor for both males and females while calibration results indicated that the models did not over- or under-fit to derivation data or over- or under-predict risk. Multiple factors associated with cancer stage at diagnosis were identified among ATP participants. While the prediction model calibration was acceptable, discrimination was poor when applied to BCGP data. Updating our models with additional predictors may help improve predictive performance.
