Objective To determine whether it is possible to predict the risk of ureteral endometriosis (UE) using a mathematical model based on preoperative findings. Design Prospective observational study conducted between January 2017 and April 2020. Setting Tertiary-level academic referral center. Patient(s) Three hundred consecutive women of reproductive age with a diagnosis of posterior deep infiltrating endometriosis (DIE) scheduled for laparoscopic surgery. Intervention(s) Before surgery, anamnestic data and the severity of endometriosis-related symptoms were evaluated, and all patients underwent a complete gynecological examination. Transvaginal and transabdominal ultrasound were performed to map the endometriotic lesion. Ureteral involvement was surgically and histologically confirmed. Main Outcome Measure(s) To select important risk factors for UE and determine a suitable functional form for continuous predictors, we used the multivariable fractional polynomial. Results UE was surgically found in 145 women (48.3%). Based on our multivariable polynomial mathematical model, UE was significantly associated with adenomyosis, parametrial involvement, and previous surgery for endometriosis. A posterior DIE nodule with a transverse diameter >1.8 cm was associated with a higher probability of ureteral involvement. Conclusions Posterior DIE nodule with a transverse diameter >1.8 cm, adenomyosis, parametrial involvement, and previous surgery for endometriosis appear to be good predictors of UE.

Objective To assess the impact on women’s reproductive outcomes of barbed sutures to repair uterine breaches during laparoscopic myomectomy compared with traditional smooth sutures. Design Retrospective, monocentric cohort study, with information on subsequent pregnancies prospectively acquired for some women. Setting Tertiary-level academic referral center. Patient(s) Women older than 18 years who had undergone a laparoscopic myomectomy and had sought pregnancy afterward, divided into two groups based on type of suture used to repair the uterine wall: group A (nonbarbed) and group B (barbed). Intervention(s) Laparoscopic removal of FIGO types 3, 4, 5, and 6 uterine leiomyomas by use of either only barbed sutures or only traditional smooth sutures to reconstruct the uterine defect. Main Outcome Measure(s) Pregnancy achievement rates, delivery modes, main pregnancy complications, perioperative complications for both kinds of suture, and the trend of the use of barbed sutures over time at our center. Result(s) Of 164 patients included, 83 were in group A and 81 in group B. Ninety-one patients (55.5%) experienced at least one postoperative pregnancy, with no differences between the groups (group A 60.5%; group B 50.6%). Of the 103 recorded postoperative pregnancies, 70 (68%) resulted in live births, 29 (28.1%) in first-trimester miscarriages, and 4 (3.9%) were ongoing. Conclusion(s) Barbed sutures have a similar impact on reproductive outcomes as smooth conventional threads, both in terms of pregnancy and obstetric complication rates, after laparoscopic myomectomy.
