Revisión bibliográfica: ecografía intraparto / Review: intrapartum ultrasound

The evaluation of labor is the clinical process by which variables are analyzed in order to determine whether the patient is in labor, which by definition includes regular uterine contractions that increase in frequency and intensity, associated with dilation cervical. This is done through the anamnesis and physical examination, specifically through the evaluation of contractions and vaginal examination, the latter is intended to specify the degree of dilation, cervical effacement that the patient presents and also allows to a certain degree, establish the presentation, attitude and variety of position in which the fetus is located. From this premise, it is proposed that vaginal examination, since it is operator dependent, is not an objective evaluation, therefore, there is a need to reach consensus on the evaluation, and in order to carry it out, evaluation with ultrasound is proposed, which has as a purpose to objectify the variety of position and presentation of the fetus. Due to the above, this article aims to capture the knowledge that is currently possessed about the uses and methodology that intrapartum ultrasound presents.

Hemoperitoneum after transperineal prostate biopsy / Hemoperitoneo tras biopsia prostática transperineal

Abstract Bleeding is the most common complication after a prostate biopsy, commonly self-limited. We describe a case of a patient who developed a hemoperitoneum after a transperineal prostate biopsy. A 65-year-old man with a history of prostate cancer diagnosed in 2016 by transurethral resection, with no further urologic control until 2020 when a rise in the serum prostate-specific antigen was diagnosed: 4.49 ng/ml. Pros tate digital rectal examination had no pathologic findings. Magnetic resonance imaging informed anequivocal lesion. A target transperineal fusion biopsy was performed, guided by ultrasound (US). Pre-surgical blood tests, including coagulogram, were normal. No immediate postoperative complications were recorded, and the patient was discharged. Hours later, he returned after a head concussion due to orthostatic hypotension and diffuse abdominal pain. Blood test showed a drop in hematocrit and hemoglobin values. Abdominal US and abdomi nopelvic computed tomography scan showed free intraperitoneal fluid and intraperitoneal hematic collection on top of the bladder of 104 × 86 mm with no active bleeding. The patient was admitted to intensive care unit due to persistent hypotension despite fluid restoration. He received a single-unit blood transfusion and had a good response to vasopressors. Abdominal pain decreased. He was finally discharged with stable hematocrit 48 hours after admission. Clinical management with no surgery or radiologic angio-embolization was required. We found no clear origin of the intraperitoneal bleeding, but we hypothesize that maybe the previous transurethral resection of the prostate made anatomical changes that facilitated blood passage to the abdominal cavity after puncture of branches from the inferior vesical artery.

Resumen La complicación más frecuente tras una biopsia prostática es el sangrado, generalmente autolimitado. Aquí describimos un caso de he moperitoneo secundario a dicho procedimiento. Hombre de 65 años con antecedentes de cáncer de próstata diagnosticado en 2016 por una resección transuretral de próstata, sin seguimiento urológico, consultó en 2020 por aumento del antígeno prostático específico: 4.49 ng/ml, asociado a tacto rectal normal y una resonancia multiparamétrica de próstata mostró una lesión indeterminada. Se realizó una biopsia prostática transperineal por fusión guiado por ecografía. Los análisis preoperatorios, incluido coagulograma, eran normales. No se registraron complicaciones intraquirúrgicas y se indicó el alta. Horas más tarde, consultó al hospital por hipotensión ortos tática y dolor abdominal difuso. Los análisis demostraron caída del hematocrito y hemoglobina. Una ecografía y posterior tomografía computada evidenciaron una colección supravesical de 104 × 86mm sin signos de sangrado activo. Se indicó internación en sala de cuidados intensivos debido a hipotensión refractaria a expansiones con requerimiento de vasopresores. Recibió una transfusión de glóbulos rojos. Por favorable evolución, 48 horas después del ingreso recibió el alta. En este caso, fue posible un manejo conservador, sin requerimiento de cirugía o embolización. Si bien no se encontró sitio exacto del sangrado, creemos que la resección transuretral previa podría haber generado cambios anatómicos que facilitaran el pasaje de sangre, posiblemente proveniente de ramas de la arteria vesical inferior a cavidad abdominal luego de la punción.

Pelvic floor muscle dysfunction at 3D transperineal ultrasound in maternal exposure to gestational diabetes mellitus: A prospective cohort study during pregnancy.

AIM: This study aimed to assess, for the first time, the dynamic morphometry of pelvic floor muscles (PFM) using three-dimensional transperineal ultrasound (3D-TPUS) and its progression at two-time points of gestation between women with and without gestational diabetes mellitus (GDM), and whether the PFM dysfunction is connected to GDM. METHODS: The study comprised 83 consecutive pregnant women with (n = 38) and without (n = 45) GDM screened at 24-30 and 38-40 weeks of gestation. 3D-TPUS and a mobility test were used to quantify PFM dynamic morphometry during maximum contraction and the Valsalva maneuver. RESULTS: When compared to the control group, GDM women had no significant variations in all levator hiatal dimensions at 24-30 weeks of gestation. Meanwhile, women with GDM experienced an increase in levator hiatal area (LHa) (p < 0.000) during PFM contraction and enlargement in LHa (p < 0.001) during Valsalva maneuver (p = 0.010) at 38-40 weeks of gestation. As a result, the mobility index among GDM women had a lower value (p = 0.000). The dynamic morphometry development of PFM in GDM women at two stages during pregnancy revealed a substantial decrease (p = 0.000) in all LHa dimensions of contraction, distension, and mobility. CONCLUSIONS: Using 3D-TPUS, we found that GDM women had a specific pattern of PFM functional changes in the third trimester of pregnancy. These initial findings revealed alterations in PFM functionality, such as decreased contractility, distensibility, or mobility. This dysfunctional PFM could contribute to the long-term development of pelvic floor dysfunction years after a GDM pregnancy.

Biopsia de próstata, acceso transperineal bajo anestesia local / Prostate Biopsy, Transperineal Access under Local Anesthesia

Objetivo La biopsia de próstata es una ayuda esencial en el diagnóstico de cáncer, siendo el método más utilizado la biopsia transrectal guiada por ultrasonido (TRUS), con una tasa diagnóstica entre el 37% y el 45%, aunque no exenta de complicaciones como infecciones, dolor o sangrado. El enfoque alternativo y seguro a las biopsias TRUS se encuentra en la biopsia transperineal (BTP), realizada comúnmente bajo anestesia regional o general. El objetivo de este estudio fue determinar la efectividad de la BTP bajo anestesia local y guía ultrasonográfica transrectal, con el impacto sobre la sensibilidad del estudio y la tasa de readmisión hospitalaria por infección. Métodos Estudio de cohorte retrospectiva en el que se evaluaron 83 pacientes sometidos a BTP con anestesia local y guía ultrasonográfica transrectal de enero de 2017 a agosto de 2018 en una ciudad intermedia de Colombia. La muestea incluyó todos los hombres mayores de 18 años con datos de historia clínica disponibles para su análisis, así como los reportes histopatológicos de las biopsias. Se excluyeron casos de rebiopsia o con datos insuficientes. El análisis de datos nominales se realizó mediante la prueba de chi cuadrado, y el de los datos numéricos, con las prubas t de Student o de Mann-Whitney. Resultados Un total de 83 pacientes, con media de edad de 65 ± 7.9 años fueron sometidos al análisis del estudio histopatológico. Se excluyeron nueve pacientes que no tenían información disponible en el registro clínico sistematizado, ni en historia clínica de formato físico. Se encontró una proporción de positividad y diagnóstico de cáncer de prostata en el 39.7% (33) de los pacientes, distribuidos así: grado de grupo 1 (69.7%; 23); grado de grupo 2 )15.2%; 5); grados de grupos 3 y 4 (3% cada uno de ellos; 2); y grado de grupo 5 (9%; 3). En total, 60% (50) fueron negativos para malignidad y, de estos el 54% (27) tuvo hiperplasia. El antibiótico profiláctico indicado en el 96.7% (80) de los casos fue una cefalosporina de primera generación, administrada en el 15% (12) por vía parenteral preoperatoria. En esta serie de casos, no se documentaron ingresos hospitalarios asociados a infección después del procedimiento. Conclusiones La biopsia de próstata por vía transperineal es una técnica con rendimiento diagnostico similar al del abordaje transrectal: es segura, rápida, de fácil acceso, con bajo costo y, sobre todo, con un riesgo insignificante de infección y sepsis. Sus beneficios son altamente representativos en un sistema de salud como el de nuestro país, y la BTP facilita el acceso de la población vulnerable del área rural y de ciudades intermedias, en las que no se dispone de un urólogo experto.

Objective Prostate biopsy is an essencial aid in cancer diagnosis, and the the most widely-used method is known as transrectal ultrasound-guided (TRUS) biopsy, with a diagnostic rate ranging from 37% to 45%; however, it is not free of complications such as infections, pain, or bleeding. The alternative and safe approach lies in the transpineal biopsy (TPB), commonly performed under regional or general anesthesia. The objetive of the present study was to determine the effectiveness of TPBunder local anesthesia and transrectal ultrasound guidance, with the impact of the sensitiviy of the study and the rate of hospital readmission due to infection. Methods Retrospective cohort study in which 83 patients underwent TPB with local anesthesia and transrectal ultrasound guidance from january 2017 and august 2018 in an intermediate city in Colombia. The sample included all male subjects older than 18 years of age with medical history data available for analysis, as well as the histopathological reports of the biopsies. Cases of rebiopsy or with insufficient data were excluded. The analysis of the nominal data was performed using the chi-squared test, and that of the numerical data, with the Student t or the Mann-Whitney test. Results A total of 83 patientswith an average age was of 65 ± + 7.9 years, had their histopathological studies analyzed. We excluded nine patients who did not have information available in the systematized clinical registry nor in the medical history in physical format. Positivity and a diagnosis of prostate cancer was found in 39.7% (33) of the patients, who were distributed like this: grade group 1 (69.7%; 23); grade group 2 (15.2%; 5); grade groups 3 and 4 (each with 3%; 2); and grade group 5 (9%; 3). In total, 60% (50) were negative for malignancy, and, of these, 54% (27) had glandulostromal hyperplasia. The indicated prophylactic antibiotic in 96.7% (80) of the cases was a first generation cephalosporin and, in 15% (12) of the cases it was administered through a preoperative parenteral route. Hospital admissions after the procedure associated with infection were not documented in the present series of cases. Conclusions Transperineal prostate biopsy is a technique with diagnostic performance similar to that of the transrectal approach: it is safe, fast, easy to access, has a low cost and, above all, presents a minimum risk of infection and sepsis. Its benefits are highly representative in a health system like that of our country, and TPB facilitates the access of the vulnerable population of the rural area and of intermediate cities in which there is no availability of an expert urologist.

Association Between Pelvic Floor Muscle Strength and Sexual Function in Postmenopausal Women.

INTRODUCTION: Although pelvic floor muscle (PFM) weakness can be associated with pelvic floor dysfunctions, knowledge about the relationship with sexual dysfunction is limited. AIM: The aim of this study was to evaluate the association between PFM strength and sexual function in postmenopausal women. METHODS: An analytical cross-sectional study was conducted on 226 sexually active heterosexual women aged 45-65 years with amenorrhea >12 months and without pelvic floor disorders. The Female Sexual Function Index (FSFI) was used for the evaluation of sexual function (total score ≤26.5 indicating sexual dysfunction). PFM strength was assessed by bidigital vaginal palpation using the modified Oxford scale (score 0-5) and was categorized into nonfunctional (scores 0-1, without contraction) and functional (scores 2-5, with contraction). Three-dimensional transperineal ultrasound was used to evaluate total urogenital hiatus area, transverse and anteroposterior diameters, and levator ani muscle thickness. MAIN OUTCOME MEASURE: The main outcome measure was to determine the relationship between sexual dysfunction and PFM strength. RESULTS: The participants were classified as functional PFM (n = 143) and nonfunctional PFM (n = 83). There were no differences between groups in clinical and anthropometric parameters. A higher percentage of menopausal hormone therapy users was observed in the group with functional PFM (39.2%) compared to the nonfunctional group (24.1%; P = .043). Women classified as functional PFM exhibited greater levator ani muscle thickness than those classified as nonfunctional (P = .049). Women with nonfunctional PFM had poorer sexual function in the desire (P = .005), arousal (P = .001), and orgasm (P = 0.006) domains and in total FSFI score (P = .006) compared to the functional group. There was a weak positive correlation of PFM strength with the desire (r = 0.35; P = .0003), arousal (r = 0.21; P = .013), and orgasm (r = 0.23; P = .033) domains and with total FSFI score (r = 0.28; P = .004). Ultrasonographic levator ani muscle thickness showed a weak positive correlation with PFM strength (r = 0.21; P = .046) and with the arousal domain (r = 0.23; P = .044). Risk analysis adjusted for age, time since menopause, parity, and body mass index showed a lower risk of sexual dysfunction in menopausal hormone therapy users (odds ratio = 0.26; 95% CI 0.11-0.60; P = .002) and in women with greater levator ani muscle thickness (odds ratio = 0.85; 95% CI 0.73-0.98; P = .025). CLINICAL IMPLICATIONS: The maintenance of PFM strength in the climacteric period is an important factor in postmenopausal women's sexual function. STRENGTH & LIMITATIONS: The main strength of the study is that, to our knowledge, this is the first study that evaluated the correlation of PFM strength and 3D transperineal ultrasound with different domains of sexual function in postmenopausal women. The main limitation is the cross-sectional design does not permit to establish a cause-effect relationship. CONCLUSION: Postmenopausal women with PFM dysfunction have poorer sexual function than women with functional PFM. Omodei MS, Marques Gomes Delmanto LR, Carvalho-Pessoa E, et al.

Anal sphincter defects and fecal incontinence 15-24 years after first delivery: a cross-sectional study.

OBJECTIVES: To establish the prevalence of external (EAS) and internal (IAS) anal sphincter defects present 15-24 years after childbirth according to mode of delivery, and their association with development of fecal incontinence (FI). The study additionally aimed to compare the proportion of women with obstetric anal sphincter injuries (OASIS) reported at delivery with the proportion of women with sphincter defect detected on ultrasound 15-24 years later. METHODS: This was a cross-sectional study including 563 women who delivered their first child between 1990 and 1997. Women responded to a validated questionnaire (Pelvic Floor Distress Inventory) in 2013-2014, from which the proportion of women with FI was recorded. Information about OASIS was obtained from the National Birth Registry. Study participants underwent four-dimensional transperineal ultrasound examination. Defect of EAS or IAS of ≥ 30° in at least four of six slices on tomographic ultrasound was considered a significant defect and was recorded. Four study groups were defined based on mode of delivery of the first child. Women who had delivered only by Cesarean section (CS) constituted the CS group. Women in the normal vaginal delivery (NVD) group had NVD of their first child and subsequent deliveries could be NVD or CS. The forceps delivery (FD) group included women who had FD, NVD or CS after FD of their first born. The vacuum delivery (VD) group included women who had VD, NVD or CS after VD of their first born. Multiple logistic regression was used to calculate adjusted odds ratios (aORs) for comparison of prevalence of an EAS defect following different modes of delivery and to test its association with FI. Fisher's exact test was used to calculate crude odds ratios (ORs) for IAS defects. RESULTS: Defects of EAS and IAS were found after NVD (n = 201) in 10% and 1% of cases, respectively, after FD (n = 144) in 32% and 7% of cases and after VD (n = 120) in 15% and 4% of cases. No defects were found after CS (n = 98). FD was associated with increased risk of EAS defect compared with NVD (aOR = 3.6; 95% CI, 2.0-6.6) and VD (aOR = 3.0; 95% CI, 1.6-5.6) and with increased risk of IAS defect compared with NVD (OR = 7.4; 95% CI, 1.5-70.5). The difference between VD and NVD was not significant for EAS or IAS. FI was reported in 18% of women with an EAS defect, in 29% with an IAS defect and in 8% without a sphincter defect. EAS and IAS defects were associated with increased risk of FI (aOR = 2.5 (95% CI, 1.3-4.9) and OR = 4.2 (95% CI, 1.1-13.5), respectively). Of the ultrasonographic sphincter defects, 80% were not reported as OASIS at first or subsequent deliveries. CONCLUSIONS: Anal sphincter defects visualized on transperineal ultrasound 15-24 years after first delivery were associated with FD and development of FI. Ultrasound revealed a high proportion of sphincter defects that were not recorded as OASIS at delivery. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

[Applicability of 3/4D transperineal ultrasound for the diagnosis of anal sphincter injury during the immediate pospartum]. / Aplicabilidad de la ecografía transperineal en 3/4D para el diagnóstico de lesiones del esfínter anal durante el posparto inmediato.

BACKGROUND: The most common cause of anal sphincter injuries in women is vaginal birth. Endo-anal ultrasound is currently used for the diagnosis of anal sphincter defect. However, due to the inconvenience caused, it is not an applicable technique during the immediate post-partum. The aim of this study was to determine whether transperineal ultrasound in 3/4D is a useful diagnostic method for the assessment of anal sphincter during the immediate post-partum. MATERIAL AND METHODS: A prospective study was conducted on the vaginal deliveries performed between September 2012 and June 2013 in the Valme University Hospital (Seville). Obstetric and foetal parameters that could influence the onset of perineal tears were studied. The patients underwent a transperineal 3/4D ultrasound and a multislice study (48hours after birth). RESULTS: The study included 146 puerperal women. The sphincter complex was assessed in all of them during the immediate post-partum. External anal injuries were observed in 10.3% of the cases. In 8.2% of cases, the primary suture of the external anal sphincter was detected during ultrasound examination, and 2.1% of asymptomatic lesions were diagnosed only with post-partum ultrasound. None of the patients reported discomfort or pain. CONCLUSIONS: The 3-dimensional transperineal ultrasound is helpful in determining the primary repair of the anal sphincter during the immediate post-partum, with no discomfort for patients, as well as for establishing those early sphincter injuries that go unnoticed during vaginal delivery.

Defect-specific rectocele repair: medium-term anatomical, functional and subjective outcomes.

BACKGROUND: Rectocele is a herniation of the anterior wall of the rectal ampulla through a defect in the rectovaginal septum causing protrusion of the posterior vaginal wall. Common symptoms include symptoms of prolapse and obstructed defecation. AIMS: To describe subjective, anatomical and functional results of defect-specific rectocele repair. MATERIALS AND METHODS: This is an internal audit of 137 women who underwent defect-specific rectocele repair. Pre- and post-operative assessment included a standardised interview, clinical examination and 3D/4D transperineal ultrasound. Outcome measures were symptoms of obstructed defecation, recurrent prolapse symptoms, clinical posterior compartment recurrence and rectocele recurrence on ultrasound. RESULTS: At a mean follow-up of 1.4 years, 117 (85%) of women considered themselves cured or improved. Thirty-four (25%) complained of recurrent prolapse symptoms and 47 (34%) symptoms of obstructed defecation, a significant reduction (P < 0.0001). Clinical recurrence (Bp ≥ -1) was seen in 19 women (14%) and recurrence on ultrasound in 27 (20%). The mean depth of recurrence was 16.6 mm (10.3-25.1). We tested multiple potential predictors of recurrence, including age, BMI, vaginal parity, previous hysterectomy and/or prolapse surgery, follow-up time, pre-operative clinical and ultrasound findings. Only hiatal area on Valsalva (OR 0.95 for sonographic recurrence, P = 0.01) and enterocele (for clinical and sonographic recurrence, OR 4.03, P = 0.01 and OR 2.72, P = 0.02, respectively) reached significance. CONCLUSION: Defect-specific rectocele repair is effective both in restitution of normal anatomy and in resolving prolapse and obstructed defecation symptoms at a mean follow-up of 1.4 years.

Anal sphincter trauma and anal incontinence in urogynecological patients.

OBJECTIVES: To determine the prevalence of evidence of residual obstetric anal sphincter injury, to evaluate its association with anal incontinence (AI) and to establish minimal diagnostic criteria for significant (residual) external anal sphincter (EAS) trauma. METHODS: This was a retrospective analysis of ultrasound volume datasets of 501 patients attending a tertiary urogynecological unit. All patients underwent a standardized interview including determination of St Mark's score for those presenting with AI. Tomographic ultrasound imaging (TUI) was used to evaluate the EAS and the internal anal sphincter (IAS). RESULTS: Among a total of 501 women, significant EAS and IAS defects were found in 88 and 59, respectively, and AI was reported by 69 (14%). Optimal prediction of AI was achieved using a model that included four abnormal slices of the EAS on TUI. IAS defects were found to be less likely to be associated with AI. In a multivariable model controlling for age and IAS trauma, the presence of at least four abnormal slices gave an 18-fold (95% CI, 9-36; P < 0.0001) increase in the likelihood of AI, compared with those with fewer than four abnormal slices. Using receiver-operating characteristics curve statistics, this model yielded an area under the curve of 0.86 (95% CI, 0.80-0.92). CONCLUSIONS: Both AI and significant EAS trauma are common in patients attending urogynecological units, and are strongly associated with each other. Abnormalities of the IAS seem to be less important in predicting AI. Our data support the practice of using, as a minimal criterion, defects present in four of the six slices on TUI for the diagnosis of significant EAS trauma.

Leiomioma parauretal / Leiomyoma paraurethral

Se reporta un caso de leiomioma parauretral en una paciente femenina, con síntomas de cuerpo extraño en vagina y dificultad para micción, El examen físico revela masa en pared anterior de vagina. El diagnóstico fue realizado por ultrasonido transperineal. La escisión quirúrgica fue realizada sin lesionar tracto urinario. Se realiza revisión de la literatura.

A case of paraurethral leiomyoma is reported in a female patient, with symptoms of a foreign body in the vagina and difficulty in urination. Physical examination reveals mass in the anterior wall of the vagina. The diagnosis was made by transperineal ultrasound. Surgical excision was performed without injuring urinary tract. Systematic literature review is performed.

Prevalence of anal sphincter injury in primiparous women.

OBJECTIVE: To determine the prevalence of obstetric anal sphincter injuries (OASIS) in a cohort of primiparous women and to evaluate their association with demographic, obstetric and ultrasound parameters. METHODS: This was a retrospective analysis of the ultrasound volume datasets of 320 primiparous women, acquired at 5 months postpartum. Tomographic ultrasound imaging (TUI) was used to evaluate the external anal sphincter (EAS). A significant EAS defect was diagnosed if a defect of > 30° was seen in four or more of six TUI slices bracketing the EAS. RESULTS: Significant EAS defects were found in 69 women (27.9% of those delivered vaginally). In nine of those a third-degree tear was diagnosed intrapartum and was sutured. In 60 women with significant defects there was no documentation of sphincter damage at birth, implying unidentified or occult defects (60/69, 87.0%). Among them, 29 had had a second-degree tear, two a first-degree tear and three an intact perineum. In 31 cases an episiotomy had been performed, with five extensions to a third-degree tear. On multivariate analysis only forceps delivery was significantly associated with OASIS. CONCLUSIONS: In this cohort of primiparous women we found OASIS in 27.9% of vaginally parous women, most of which had not been diagnosed in the delivery suite. There seems to be a need for better education of labor-ward staff in the recognition of OASIS. On the other hand, it is conceivable that some defects may be masked by intact tissue. The significance of such defects remains doubtful. Forceps delivery was the only identifiable risk factor.

Monitoreo del borrado del cuello uterino con sonografía transperineal: posible significancia pronóstica / Monitoring of cervical shortening with transperineal sonography: possible prognostic significance

Monitorear los cambios en la longitud, ancho y forma del cuello uterino, con sonografía transperineal en las seis últimas semanas del embarazo y su posible significancia pronóstica. En 97 embarazadas normales atendidas en consulta prenatal de rutina, a las 34-40 semanas de gestación, se practicaron 173 mediciones de la longitud y ancho del cuello uterino, mediante sonografía transperineal. Grupo Médico Nova Cecil, La Trinidad. De las 97 embarazadas 82 parieron normalmente y 15 fueron intervenidas por estrechez pélvica. En los partos normales, en el promedio, por el aumento del ancho del cuello en 1 mm, la longitud del cuello decreció 0,37 mm en el rango de mediciones realizadas. Además, la pendiente fue significativamente diferente de cero. Por el contrario, en las intervenidas estos cambios no presentaron significancia estadística. Mientras la correlación entre largo y ancho del cuello fue estadísticamente significativa en las pacientes con parto normal, no ocurrió así en las pacientes intervenidas. Estos cambios tienen significancia pronóstica

To monitor uterine cervix’ length, wide and form with transperineal sonography in the last six weeks of pregnancy and their prognostic significance. In 97 normal pregnant women attending routine antenatal care at 34-40 gestational weeks, we performed 173 measurements of the length and wide of the cervix, by transperineal sonography. Grupo Médico Nova Cecil, La Trinidad. Out of the 97 pregnant women 82 delivered vaginally and 15 were operated due to pelvic stenosis. In the normal deliveries, on the average, for every increase in the cervix width of 1 mm, the cervix length decreases 0,37 over the range of measurements made. Besides, the slope was statistically significant from zero. On the contrary, in the caesarean cases these changes did not were statistically significant. While correlation between length and wide was statistically significant in normal deliveries, this relationship was absent in the caesarean cases. These changes have prognostic significance

Reparo transperineal de retocele: avaliação do grau de satisfação, dispareunia e recidiva pós-operatória / Transperineal repair for rectocele: grade of satisfaction and postoperatory dispareunia and recurrence

A retocele é uma disfunção pélvica pobremente diagnosticada, apesar de sua prevalência significativa. Seu reconhecimento é essencial para o tratamento de determinados casos, como constipação refratária. A sintomatologia é vaga, e nem sempre associada ao prolapso. O tratamento clínico é ineficaz quando utilizado isoladamente. Existem várias técnicas, e dentre elas a abordagem transperineal pode ser considerada uma opção adequada na correção do prolapso. Nas 12 pacientes objetos de nosso estudo, houve melhora significativa do padrão evacuatório, uma resposta aceitável no tratamento da dispareunia, com índice de recidiva tolerável e alto grau de satisfação pós-operatória. A comparação com as demais técnicas ainda exige estudos comparativos mais significativos, com amostras mais expressivas. Até o momento, qualquer análise comparativa entre as técnicas cirúrgicas utilizadas pode ser falha.

Rectocele is a poorly diagnosed pelvic dysfunction, despite its significant prevalence. Its recognition is essential for the treatment of certain cases as refractory constipation. The symptoms are vague and not always associated with prolapse. Clinical treatment is ineffective when used alone. There are several techniques, being the transperineal approach an appropriate option for the correction of prolapse. The target of this data is a group of 12 female patients with rectocele: they experienced significant improvement in the defecation standard, an acceptable response in the treatment of dyspareunia, with acceptable recurrence rate and high degree of satisfaction after surgery. The comparison with other techniques still requires significant further comparative studies with samples more expressive. To date, any comparative analysis between the surgical techniques used may be failure.
