Introduction: Anesthesia choice during the procedural management of suspected renal colic during pregnancy may vary based on available resources and patient or provider preferences, as there are no specific recommendations. Our objective was to evaluate whether preterm birth (<37 weeks) was associated with anesthesia type, anesthesia timing by trimester, or procedure type.

Methods: We retrospectively identified pregnant patients who required procedural management with ureteral stent, percutaneous nephrostomy (PCN), or ureteroscopy (URS) for suspected renal colic based on laboratory and imaging findings from 2009-2021 at our center.

Article Synopsis
  • * Out of 100 reviewed patients, 78 were analyzed, revealing that those who underwent PCN had the highest total mean radiation exposure (286.9 mGy) and required significantly more procedures compared to the other two interventions.
  • * The results indicated that PCN not only led to higher radiation exposure but also resulted in more complications, with over 40% of PCNs experiencing dysfunction and an average exchange period of 16.5 days.

Study Objective: The objective of this study is to compare quality of life (QOL) for myomectomy with hysterectomy 1 to 5 years after surgical management for fibroids. This study evaluated the difference in QOL in a population of women of reproductive age, including those who desire fertility.

Design: A retrospective cohort study.

Gynecologic emergencies may result from congenital uterine anomalies (CUAs) with outflow tract obstruction. Not limited to the "classic" presentation of an adolescent amenorrheic pain patient, such anomalies should be part of the differential diagnosis for adult female patients presenting with severe pelvic pain. Obstructed rudimentary noncommunicating cavitary horns may result in severe chronic or acute pain and necessitate urgent surgical management.

Purpose: To compare morphokinetic parameters in embryos obtained from women with and without endometriosis.

Methods: We evaluated a total of 3471 embryos resulting from 434 oocyte retrievals performed at a single academic center. One thousand seventy-eight embryos were obtained from women affected by endometriosis and 2393 came from unaffected controls.

Article Synopsis
  • Implantation is an important part of having a baby, where the embryo connects to the mother’s womb after fertilization.
  • Sometimes, embryos don’t stick to the womb as they should, which is called recurrent implantation failure, and this can happen even after trying multiple times.
  • Researchers are studying many reasons for this failure, like genetics, the mother’s immune system, and other health factors, but there isn’t one simple solution yet.

Global average life expectancy continues to rise. As aging increases the likelihood of frailty, which encompasses metabolic, musculoskeletal, and cognitive deficits, there is a need for effective anti-aging treatments. It is well established in model organisms that dietary restriction (DR), such as caloric restriction or protein restriction, enhances health and lifespan.

Purpose: To compare growth factor and cytokine profiles in the endometrial secretions of patients with and without endometriosis to determine whether a particular protein profile is predictive of the disease.

Methods: Patients undergoing laparoscopic gynecologic surgery for benign indications were recruited for this prospective cohort study. Prior to surgery, endometrial fluid was aspirated and multiplex immunoassay was used to quantify 7 cytokines and growth factors.

Increases in delayed childbearing worldwide have elicited the need for a better understanding of the biological underpinnings and implications of age-related infertility. In women 35 years and older the incidences of infertility, aneuploidy, and birth defects dramatically increase. These outcomes are a result of age-related declines in both ovarian reserve and oocyte quality.

Introduction: Endometriosis is estimated to affect 10% of reproductive-aged women. The gold standard for treatment is surgery; however, surgery carries a significant morbidity and cost burden. There is an ongoing need for safe, effective medical therapies for endometriosis patients, both in conjunction with and independent of surgical interventions.

Infertility affects 30% to 50% of women with endometriosis. Women with endometriosis are at risk of decreased ovarian reserve, both because of the pathophysiology of the disease and iatrogenic injury resulting from surgical intervention. Fertility preservation must occur at multiple levels, including careful selection of surgical candidates, avoidance of repeat procedures, and meticulous surgical technique.

Purpose: To evaluate the available randomized controlled trials (RCTs) in the literature investigating the use of gonadotropin-releasing hormone agonist (GnRHa) co-treatment for ovarian preservation in women receiving chemotherapy.

Methods: A systematic review of the literature was performed from 1960 through 2017 to identify relevant RCTs. Included patients had lymphoma, ovarian cancer, or breast cancer.

Fibroid uterus can be managed medically, surgically, or through non-extirpative procedures, depending on the clinical situation. Myomectomy may be beneficial, especially to those desiring to preserve the uterus and/or fertility, with outcomes comparable to those of hysterectomy, with a laparoscopic approach being favored when feasible. For definitive therapy, hysterectomy can be pursued where the surgical approach should be individualized.

Background And Objectives: Breast cancer treatment can cause premature ovarian failure, yet the majority of young cancer patients do not receive adequate education about treatment effects before initiating chemotherapy. We studied the impact of an oncofertility program on access to fertility preservation.

Methods: An oncofertility program was initiated to foster collaboration between oncologists and reproductive endocrinologists, and to help increase access to fertility preservation.

Background: Adjuvant tamoxifen reduces breast cancer recurrence risk and mortality; however, initiation and treatment persistence are poor for younger patients. We hypothesized that a unique set of factors, including fertility concerns, would contribute to the poor tamoxifen use among premenopausal patients.

Methods: From 2007 to 2012, 515 premenopausal patients younger than age 45 years, with stage 0 to III hormone receptor-positive breast cancer, for whom tamoxifen was recommended, were identified.
