Pregnancy outcomes after ultrasound-guided high-intensity focused ultrasound (USgHIFU) for conservative treatment of uterine fibroids: experience of a single institution.

OBJECTIVE: To assess the impact of ultrasound-guided high-intensity focused ultrasound (USgHIFU) ablation for uterine fibroids on fertility. MATERIAL AND METHODS: A retrospective observational study was conducted of 560 reproductive-age women with symptomatic uterine fibroids who underwent USgHIFU therapy at Mútua Terrassa University Hospital, Spain, between February 2008 and February 2018. We analyzed pregnancy outcomes including time to conception, pregnancy approach, gestational age, delivery mode, neonatal outcomes and complications during pregnancy and delivery. RESULTS: After USgHIFU treatment, 71 pregnancies were obtained in 55 patients. Of these, 58 (82%) cases were natural pregnancies and 13 (18%) were in vitro fertilization (IVF) pregnancies. The median time to conception was 12 (range 1-72) months. There were 43 (61%) successful deliveries, including a twin gestation, 22 (31%) spontaneous abortions and 6 (8%) therapeutic abortions. The rate of full-term deliveries was 91% (39/43) and the remaining 9% (4/43) were preterm deliveries. Of the 44 live births, 25 (57%) were born vaginally and 19 (43%) by cesarean section. The complications reported included 3 women with retained placenta (7%), 2 with placenta previa (5%) and 1 with severe preeclampsia (2%). The mean birth weight was 3.1 (range: 1.4-4.3) kg, and except for a baby born with a tetralogy of Fallot, all newborns developed well without complications during postpartum and breastfeeding. CONCLUSION: Patients undergoing USgHIFU treatment of uterine fibroids can achieve full-term pregnancies with few intrapartum or postpartum complications. More studies are required to compare fertility and perinatal outcomes between patients who underwent or not USgHIFU.

Postpartum two- and three-dimensional ultrasound evaluation of anal sphincter complex in women with obstetric anal sphincter injury.

OBJECTIVE: To compare the sensitivity and specificity of two- (2D) and three- (3D) dimensional transperineal ultrasound (TPUS) and 3D endovaginal ultrasound (EVUS) with the gold standard 3D endoanal ultrasound (EAUS) in detecting residual defects after primary repair of obstetric anal sphincter injuries (OASIS). METHODS: External (EAS) and internal (IAS) anal sphincters were evaluated by the four ultrasound modalities in women with repaired OASIS. 2D-TPUS was evaluated in real-time, whereas 3D-TPUS, 3D-EVUS and 3D-EAUS volumes were evaluated offline by six blinded readers. The presence/absence of any tear in EAS or IAS was recorded and defects were scored according to the Starck system. Sensitivity, specificity and predictive values were calculated, using 3D-EAUS as reference standard. Inter- and intraobserver analyses were performed for all 3D imaging modalities. Association between patients' symptoms (Wexner score) and ultrasound findings (Starck score) was calculated. RESULTS: Images from 55 patients were analyzed. Compared with findings on 3D-EAUS, the agreement for EAS evaluation was poor for 3D-EVUS (κ = 0.01), fair for 2D-TPUS (κ = 0.30) and good for 3D-TPUS (κ = 0.73). The agreement for IAS evaluation was moderate for both 3D-EVUS (κ = 0.41) and 2D-TPUS (κ = 0.52) and good for 3D-TPUS (κ = 0.66). Good intraobserver (3D-EAUS, κ = 0.73; 3D-TPUS, κ = 0.78) and interobserver (3D-EAUS, κ = 0.68; 3D-TPUS, κ = 0.60) agreement was reported. Significant association between Starck and Wexner scores was found only for 3D-EAUS (Spearman's rho = 0.277, P = 0.04). CONCLUSIONS: 2D-TPUS and 3D-EVUS are not accurate modalities for the assessment of anal sphincters after repair of OASIS. 3D-TPUS shows good agreement with the gold standard 3D-EAUS and a high sensitivity in detecting residual defects. It, thus, has potential as a screening tool after primary repair of OASIS. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

How can we measure bladder volumes in women with advanced pelvic organ prolapse?

OBJECTIVES: To compare bladder volumes determined by three different formulae using measurements obtained from two-dimensional translabial ultrasound (2D-US), with true bladder volumes, in women with advanced pelvic organ prolapse (POP). METHODS: This was a prospective observational multicenter study of consecutive women on the waiting list for prolapse surgery in 24 gynecology departments. All women had a symptomatic genital prolapse Stage 2 or higher according to the Pelvic Organ Prolapse Quantification System (POP-Q). Bladder volumes were calculated before and after spontaneous voiding by 2D-US, and true bladder volumes were determined by micturition and catheterization. Volumes determined by US were calculated using three formulae (Haylen, Dietz and Dicuio). Correlation was calculated between the volume determined by US measurement before micturition and the true volume, and also between the volume determined by US measurements after micturition and the true volume. Correlations (Spearman's rho) and concordance (intraclass correlation coefficient (ICC)) were estimated for each of the three formulae considered. RESULTS: One-hundred and eighty-six women with POP were included in the study. A total of 349 bladder volumes (186 before micturition and 163 after micturition) were obtained. Good correlation (rho, 0.818-0.849) and concordance (ICC, 0.827-0.898) were found between total measured volume (volume of spontaneous bladder voiding + volume obtained from catheterization) and the volume determined by US using the three different formulae, as well as between the post-void residual volume measured by catheterization and the post-void volume calculated by US using the three formulae (rho, 0.739-0.777; ICC, 0.840-0.877). CONCLUSIONS: Bladder volumes in women with advanced POP can be measured easily by 2D-US. Volumes determined using the three different formulae show good correlations and concordance with true bladder volume.

Post-void residual and voiding dysfunction symptoms in women with pelvic organ prolapse before and after vaginal surgery. A multicenter cohort study. / Residuo posmiccional y síntomas de disfunción de vaciado en mujeres con prolapso de órganos pélvicos antes y después de la cirugía vaginal. Estudio de cohortes multicéntrico.

OBJECTIVES: The present study evaluates the impact of vaginal surgery for pelvic organ prolapse (POP) on voiding dysfunction (VD) symptoms and post-void residual (PVR) one year after the intervention. MATERIAL AND METHODS: Epidemiological, longitudinal, prospective study. Thirty-nine gynecology units included women with symptomatic POP grade 2 or higher according to the Pelvic Organ Prolapse Quantification (POP-Q) system, who would undergo surgery for vaginal prolapse (CIRPOP-IUE study). Sociodemographic and clinical variables were collected before and after the intervention. At both visits, patients completed the 'Epidemiology of Prolapse and Incontinence Questionnaire' (EPIQ) and 'Pelvic Floor Distress Inventory' (PFDI-20) questionnaire. PVR volume was measured by bladder catheterization immediately after spontaneous urination. RESULTS: VD symptoms were present in 50% cases before the intervention. PVR was measured in 277 women of which 116 (41.87%) were >50ml and 42/277 (15.2%) were >100ml. Objective and subjective reduction in VD symptoms was observed one year after the intervention. Mean PVR volume was reduced with statistical significance, from a mean (SD) of 66.4 (68.9)ml to 48.3 (51.3)ml. The number of patients who reported difficulty in emptying and sensation of incomplete emptying on the EPIQ and PFDI-20 questionnaires also decreased. CONCLUSIONS: In general, improved voiding functions were observed in the CIRPOP-IUE study through a decrease in specific VD symptoms and a reduction in mean PVR volume.

Using microbubble sonographic contrast agent to enhance the effect of high intensity focused ultrasound for the treatment of uterine fibroids.

OBJECTIVE: To evaluate the effects of the ultrasound contrast agent SonoVue in enhancing the ablative effects of Ultrasound-Guided high-intensity focused ultrasound (HIFU) on different sub-types of uterine fibroids. MATERIALS AND METHODS: In this study, 390 fibroids from 319 patients were retrospectively evaluated, among which 155 were treated with SonoVue and 235 were without SonoVue during HIFU ablation. The efficacy of HIFU was evaluated using magnetic resonance scanning (MRI) in all patients. RESULTS: The total ablation time to achieve the same non-perfused volume was significantly shortened with SonoVue. The average energy used and the acoustic energy for treating 1 mm(3) (EEF) was less when SonoVue is used as enhancing agent. The non-perfused volume (NPV) was measured by post-HIFU MRI and the mean fractional ablation was calculated. Mean NPV was 74% (range: 15%-100%) in the HIFU-only group and 75% (range: 17%-100%) in the HIFU+ SonoVue group. However, for T2 MRI low intensity signal fibroids, NPV in the SonoVue group reached 83% (range: 20%-100%) that was significantly higher than in the HIFU-only group, which was 76% (range: 15%-100%). No differences in adverse events were observed between the two groups. CONCLUSIONS: Our observations demonstrate that the use of therapeutic SonoVue during the HIFU procedure can significantly decrease the ablation time and the energy requirement for the treatment of the same fibroid volume in all types of fibroids.

Positive versus negative sentinel nodes in early breast cancer patients: axillary or loco-regional relapse and survival. A study spanning 2000-2012.

Sentinel Node Biopsy (SNB) is a minimally invasive alternative to elective axillary lymph node dissection (ALND) for nodal staging in early breast cancer. The present study was conducted to evaluate prognostic implications of a negative sentinel node (SN) versus a positive SN (followed by completion ALND) in a closely followed-up sample of early breast cancer patients. We studied 889 consecutive breast cancer patients operated for 908 primaries. Patients received adjuvant therapy with chemotherapy, hormone therapy and eventually trastuzumab. Radiation therapy was based on tangential radiation fields that usually included axillary level I. Median follow-up was 47 months. Axillary recurrence was seen in 1.2% (2/162) of positive SN patients, and 0.8% (5/625) of negative SN patients (p = n.s.). There was an overall 3.2% loco-regional failure rate (29/908). Incidence of distant recurrence was 3.3% (23/693) for negative SN patients, and 4.6% (9/196) for positive SN patients (p = n.s.). Overall mortality rate was 4% (8/198) for positive SN patients, while the corresponding specific mortality rate was 2.5% (5/198). For patients with negative SNs, overall mortality was 4.9% (34/693), and the specific mortality was 1.4% (19/693) (p = n.s.). We did not find significant differences in axillary/loco-regional relapse, distant metastases, disease-free interval or mortality between SN negative and SN positive patients, with a follow-up over 4 years.

Estudio de cohortes multicéntrico / Post-void residual and voiding dysfunction symptoms in women with pelvic organ prolapse before and after vaginal surgery. A multicenter cohort study

OBJETIVOS: El presente trabajo evalúa el impacto de la cirugía vaginal del prolapso de órganos pélvicos (POP) en los síntomas de disfunción de vaciado (DV) y en el residuo posmiccional (RPM) un año después de la intervención. MATERIAL Y MÉTODOS: Estudio epidemiológico, longitudinal y prospectivo. Un total de 39 unidades de ginecología incluyeron mujeres con POP sintomático de grado 2 o superior según la clasificación Pelvic Organ Prolapse Quantification (POP-Q) que iban a ser sometidas a cirugía del prolapso por vía vaginal (estudio CIRPOP-IUE). Se recogieron variables sociodemográficas y clínicas antes y después de la intervención. En ambas visitas, las pacientes cumplimentaron los cuestionarios Epidemiology of Prolapse and Incontinence Questionnaire (EPIQ) y Pelvic Floor Distress Inventory (PFDI-20). El RPM se midió por sondaje vesical inmediatamente después de una micción espontánea. RESULTADOS: El 50% de las mujeres refirieron síntomas de DV antes de la intervención. El RPM se midió en 277 mujeres de las cuales en 116 (41,87%) fue > 50 ml y en 42/277 (15,2%) fue > 100 ml. Un año tras la intervención, se observó una reducción objetiva y subjetiva de los síntomas de DV. El RPM medio se redujo de forma estadísticamente significativa, pasando de una media (DE) de 66,4 (68,9) ml a 48,3 (51,3) ml. También disminuyó el número de pacientes que reportaron dificultad de vaciado y sensación de vaciado incompleto en los cuestionarios EPIQ y PFDI-20. CONCLUSIONES: En general, se observó una mejora de la función miccional tanto a través de la disminución de los síntomas específicos de DV como de la reducción del volumen medio del RPM

Diagnóstico prenatal de un caso de gastrosquisis fetal / A case of fetal gastroschisis diagnosed at 12 week is reported

Se describe un caso de gastrosquisis fetal diagnosticado a las 12 semanas. Se discute la etiopatogenia, el diagnóstico tanto ecográfico como por RMN, haciendo especial hincapié en esta última por su reciente utilización en el diagnóstico de las malformaciones congénitas. Aunque la ultrasonografía continua siendo la primera técnica de diagnóstico por la imagen de las alteraciones fetales durante la gestación, debido a su bajo coste y a su disponibilidad, la RMN, utilizando secuencias HASTE, ofrece ventajas en la valoración de órganos y estructuras fetales normales. Así mismo, se tratará del diagnóstico diferencial con otra enfermedad parecida, el onfalocele (AU)
