RESUMO
Resumen OBJETIVO: Reportar la experiencia en la práctica de cerclajes con indicación profiláctica y terapéutica en pacientes con embarazo único o múltiple, con insuficiencia cervical. Además, informar los días de gestación ganados y comparar las técnicas quirúrgicas con los cerclajes. MATERIALES Y MÉTODOS: Estudio retrospectivo, descriptivo, comparativo y transversal efectuado entre enero de 2011 y enero de 2018. Criterios de inclusión: pacientes a quienes se efectuó un cerclaje y el embarazo finalizó en nuestra unidad. Variables de estudio: edad, IMC, embarazos, abortos, días de gestación ganados, días en que se efectuó el procedimiento quirúrgico, semanas de gestación cumplidas a la finalización del embarazo, tiempo quirúrgico, medicamentos (tocolíticos y antibióticos), complicaciones a partir del cerclaje hasta la finalización del embarazo. Para el análisis descriptivo se utilizó el paquete estadístico IBM SPSS (versión 22); la distribución se obtuvo con t de Student, se aplicó la prueba de normalidad Shapiro-Wilk y las variables con distribución normal se analizaron, comparativamente, con ANOVA y las de distribución anormal con la prueba Kruskal-Wallis. RESULTADOS: Se analizaron 37 casos en los que el cerclaje prolongó 116.14 ± 47.4 días la gestación, con finalización promedio del embarazo a los 246.41 ± 26.54 días. El cerclaje Shirodkar fue superior: prolongó la gestación 134.69 días con finalización del embarazo a las 36 ± 2 semanas. CONCLUSIONES: En pacientes con insuficiencia cervical el cerclaje es una opción para prolongar el embarazo. La técnica Shirodkar tuvo márgenes de mayor seguridad hasta la finalización del embarazo (más de 34 semanas). El comportamiento en embarazos múltiples es similar, por lo que en caso de insuficiencia cervical debe aplicarse.
Abstract OBJECTIVE: To report the experience in the practice of cerclages with prophylactic and therapeutic indication in patients with single or multiple pregnancy, with cervical incompetence. In addition, report the days of pregnancy gained, compare surgical techniques and cerclages in single and multiple gestations. MATERIALS AND METHODS: Retrospective, descriptive, comparative and cross-sectional study carried out between January 2011 and January 2018. Inclusion criteria: patients who had a cerclage and the pregnancy ended in our unit. Study variables: age, BMI, pregnancies, abortions, days of gestation earned, days in which they were placed, weeks of gestation completed at the end of pregnancy, surgical time, medications (tocolytics and antibiotics), complications from the placement of the cerclage until the end of pregnancy. For the descriptive analysis the statistical package IBM SPSS (version 22) was used; the distribution was obtained with Student's t test, the Shapiro-Wilk normality test was applied and the variables with normal distribution were analyzed, comparatively, with ANOVA and those with abnormal distribution with the Kruskal-Wallis test. RESULTS: 37 cases were analyzed in which the placement of cerclage prolonged 116.14 ± 47.4 days gestation, with an average termination of pregnancy at 246.41 ± 26.54 days. The Shirodkar cerclage was superior: it extended gestation 134.69 days with the end of pregnancy at 36 ± 2 weeks. CONCLUSIONS: In patients with cervical incompetence cerclages are an option to prolong pregnancy. The Shirodkar technique had higher safety margins until the end of pregnancy (more than 34 weeks). The behavior in multiple pregnancies is similar, so in case of cervical incompetence should be applied.
RESUMO
BACKGROUND: Embryo transfer is a critical point for success in IVF cycles. Many factors should be considered when performing an embryo transfer such as: embryo quality and number, soft versus rigid catheter, easy of the transfer, physician technique, ultrasound guide during transfer, among others. OBJECTIVE: Evaluate two different embryo transfer systems performed by six physicians with the same protocol. MATERIAL AND METHODS: We evaluated 308 embryo transfers performed from January 2006 to December 2008 by six physicians with two different systems. We only included patients with good quality in embryos and endometrium. Both systems were analyzed in each of the six physicians. RESULTS: Similar characteristics in number of transferred embryos, number of cells in each embryo and quality of them, were found in both groups. There were no significant differences between both systems in the characteristics of the couple nor the mentioned above. Most of the transfers n = 252 (81.81%), were realized by two of the six physicians, however, the pregnancy rate did not show significant differences between these physicians and the less experienced ones. CONCLUSIONS: With the obtained results, it could be supposed that the most influential factor in the outcome is the operator experience in the use of each system and not the system itself.

BACKGROUND: intrauterine insemination should be offered to couples with unexplained infertility, given its effectiveness and compared to in vitro fertilization and embryo transfer, is less invasive and requires less resources. It also should be offered to couples with male factor infertility in selected patients with induction of ovulation to increase the chances of pregnancy. OBJECTIVE: to determine the rate of pregnancy with intrauterine insemination in couples with infertility. MATERIAL AND METHODS: descriptive and retrospective study of 500 couples with female, male and combined infertility, primary or secondary, managed with homologous insemination, with controlled ovarian stimulation and programmed ovulation, in patients with at least one permeable salpinx, FSH <12 IU/L and > 5 x 10(6) mobile and normal sperm. Ultrasonografic follicular follow-up and ovulation triggering according to findings, performing insemination 36 hours after the shooting, with luteal phase support with progesterone. RESULTS: 1.6 cycles on average, female infertility 65.8%, 21% male and combined 13.2%, age average 32 years of women and 36 years of man, average ovarian stimulation 8 days. Pregnancy in 19.5% of the patients, of these, 65.1% under the age of 35 years, 33.3% from 35 to 40 years and 1.5% older than 40 years. Pregnancy at term 77.08%, miscarriage 11.45% and unknown resolution at 11.45%. Twin pregnancy 14.61% and high fetal order 5.7%. Pregnancy with female infertility 64%, male 22.3% and combined 13.5%. Pregnancy with endometrial <8 mm 9.8%, 8-15 mm 86.4% >15 mm 3.6%. With trilaminar endometrium 72.3%, dense 12.5%, linear 0.5%. CONCLUSION: The rate of pregnancy in intrauterine insemination hardly exceeds 20%. The determinants for this are the women age, type of infertility and endometrial characteristics. It was also noted high twin pregnancy and high fetal order.
