ABSTRACT Objective To assess testicular volumes and sexual maturation in patients with testicular torsion. Methods A retrospective analysis of consecutively treated patients with testicular torsion between 2016 and 2018. Age, pubic hair staging (Tanner), and by ultrasonography, volume of the unaffected testis (in cubic centimeters) were evaluated either immediately before surgery or at the first postoperative visit. Patients with previous testicular disease, such as cryptorchidism, or with no records of testicular volume were excluded. The analysis included descriptive statistics and Bayesian regression. Results We treated 149 patients during the study period, and 141 (94.6%, median age 17.3 years) met the inclusion criteria. Median testicular volume was 13.0cm3 (interquartile range of 10.5-15.2), with similar right and left volumes (12.9cm3versus 13.3cm3; p=0.94). Sixty-five (46.1%) patients were Tanner stage IV, 17 (12.1%) stage III, and 59 (41.8%) stage V. Conclusion In this study, we were able to estimate volumes of testicular torsion, which aggregated around late puberty values (13.0cm3 for the whole dataset, 12.2cm3 for patients <25 years), suggesting that testicular hypermobility, due to congenital anatomical abnormalities, remains quiescent until the organ reaches a critical volume, after which torsion becomes possible. These findings provide a tentative explanation for the disease’s age distribution.

Resumo Objetivo Investigar a viabilidade do treinamento dos músculos do assoalho pélvico (TMAP) por meio de gameterapia no alívio de sintomas urinários em mulheres climatéricas com incontinência urinária (IU) de esforço ou mista. Métodos Ensaio clínico randomizado, dividido em dois grupos: Gameterapia (G_Game) e Controle (G_Controle). Ambos os grupos receberam recomendações sobre TMAP não supervisionado, e G_Gametambém recebeu TMAP supervisionado por meio de gameterapia. Após 5 semanas consecutivas, a viabilidade foi investigada considerando a aderência das participantes, sintomas urinários (avaliados pelo questionário International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form [ICIQ-UI-SF]) e função do assoalho pélvico (esquema PERFECT: power, endurance, repetition, fast). Os testes exatos de Fisher, Kruskal-Wallis, sinal de Wilcoxon pareado e Mann-Whitney U foram usados pela análise de intenção de tratar, usando o software STATA 15.1 (StataCorp, College Station, TX, EUA). Resultados O presente estudo incluiu 20 mulheres por grupo e observou uma maior adesão no G_Game. Na análise intragrupo, foi observada diminuição no escore do ICIQUI- SF emambos os grupos (de 14,0 para 10,0; de 13,5 para 0), associada ao aumento da resistência (de 2,5 para 3,5; de 2,5 para 4,0) em G_Control e G_Game, respectivamente. Além disso, houve um aumento concomitante no power (de 2,0 para 3,0), repetition (de 3,0 para 5,0) e fast (de 10,0 para 10,0) dosmúsculos do assoalho pélvico (MAPs) no G_Game. Na análise intergrupos, foi observada redução da IU (p<0,001; r=0,8), assim como do power (p=0,027; r=0,2) e da endurance (p=0,033; r=0,3) dos MAPs no G_Game. Conclusão A viabilidade do TMAP supervisionado por meio de gameterapia foi identificada pela observação da aderência das participantes, pelo alívio dos sintomas urinários e pela melhora da função dos MAPs.

Abstract Objective To investigate the feasibility of pelvic floor muscle training (PFMT) through gametherapy for relieving urinary symptoms of climacteric women with stress ormixed urinary incontinence (UI). Methods Randomized clinical trial, divided into two groups: Gametherapy (G_Game) and Control (G_Control). Both groups received recommendations about unsupervised PFMT, and G_Game also received supervised PFMT through gametherapy. After 5 consecutive weeks, the feasibility was investigated considering participant adherence, urinary symptoms (evaluated by the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form [ICIQ-UI-SF] questionnaire), and pelvic floor function (PERFECT Scheme: power, endurance, repetition and fast). The Fisher exact, Kruskal-Wallis, Wilcoxon sign paired, and Mann-Whitney U tests were used by intention-to-treat analysis, using STATA 15.1 (StataCorp, College Station, TX, USA) software. Results The present study included 20 women per group and observed a higher adherence in G_Game. In the intragroup analysis, a decrease in the ICIQ-UI-SF score was observed in both groups (14.0 to 10.0; 13.5 to 0), associated with increased endurance (2.5 to 3.5; 2.5 to 4.0) in G_Control and G_Game, respectively. Moreover, there was a concomitant increase in pelvic floor muscles (PFMs) power (2.0 to 3.0), repetition (3.0 to 5.0), and fast (10.0 to 10.0) in G_Game. In the intergroup analysis, a reduction of UI was observed (p<0.001; r=0.8), as well an increase in PFM power (p=0.027, r=0.2) and endurance (p=0.033; r=0.3) in G_Game. Conclusion The feasibility of supervised PFMT through gametherapy was identified by observing participant adherence, relief of urinary symptoms, and improvement in PFM function.

ABSTRACT Purpose To estimate statewide presentation delay, misdiagnosis rate, inter-hospital transfer times and testicular salvage for testicular torsion patients treated in our state’s public health system. Patients and Methods Case series of consecutive testicular torsion patients treated in our state’s public health system between 2012-2018. Predictors included presentation delay (time from symptoms to first medical assessment), facilitie’s level-of-care (primary, secondary, tertiary), first diagnosis (torsion, epididymitis, other), Doppler-enhanced ultrasound request (Doppler-US) and inter-hospital transfer times, with surgical organ salvage as the main response. We used Bayesian regression to estimate the effect of first examining facilitie’s level-of-care, first diagnosis, and Doppler-US on transfer time. Results 505 patients were included, most (298, 59%) with presentation delay >6 hours. Misdiagnosis at first examining facility raised transfer time from median 2.8 to 23.4 (epididymitis) and 37.9 hours (other) and lowered testicular salvage rates from 60.3% (torsion) to 10.7% (epididymitis) and 18.3% (other). Doppler-US had negligible effects on transfer time once controlling for misdiagnosis in the regression model. Although organ salvage in patients presenting before 6 hours at the tertiary facility was high (94.6%, and about 20% lower for those presenting at lower levels-of-care), the overall salvage rate was more modest (46%). Conclusion Our low overall testicular salvage rates originated from a large proportion of late presentations combined with long transfer times caused by frequent misdiagnoses. Our results indicate that efforts to improve salvage rates should aim at enhancing population-wide disease awareness and continuously updating physicians working at primary and secondary levels-of-care about scrotal emergencies.

ABSTRACT Purpose: To analyze pre-transplantation and early postoperative factors affecting post-transplantation urine output and develop a predictive nomogram. Patients and Methods: Retrospective analysis of non-preemptive first transplanted adult patients between 2001-2016. The outcomes were hourly diuresis in mL/Kg in the 1st (UO1) and 8th (UO8) postoperative days (POD). Predictors for both UO1 and UO8 were cold ischemia time (CIT), patient and donor age and sex, HLA I and II compatibility, pre-transplantation duration of renal replacement therapy (RRT), cause of ESRD (ESRD) and immunosuppressive regimen. UO8 predictors also included UO1, 1st/0th POD plasma creatinine concentration ratio (Cr1/0), and occurrence of acute cellular rejection (AR). Multivariable linear regression was employed to produce nomograms for UO1 and UO8. Results: Four hundred and seventy-three patients were included, mostly deceased donor kidneys’ recipients (361, 70.4%). CIT inversely correlated with UO1 and UO8 (Spearman's p=-0.43 and −0.37). CR1/0 inversely correlated with UO8 (p=-0.47). On multivariable analysis UO1 was mainly influenced by CIT, with additional influences of donor age and sex, HLA II matching and ESRD. UO1 was the strongest predictor of UO8, with significant influences of AR and ESRD. Conclusions: The predominant influence of CIT on UO1 rapidly wanes and is replaced by indicators of functional recovery (mainly UO1) and allograft's immunologic acceptance (AR absence). Mean absolute errors for nomograms were 0.08 mL/Kg h (UO1) and 0.05 mL/Kg h (UO8).

ABSTRACTThe use of meshes has become the first option for the treatment of soft tissue disorders as hernias and stress urinary incontinence and widely used in vaginal prolapse's treatment. However, complications related to mesh issues cannot be neglected. Various strategies have been used to improve tissue integration of prosthetic meshes and reduce related complications. The aim of this review is to present the state of art of mesh innovations, presenting the whole arsenal which has been studied worldwide since composite meshes, coated meshes, collagen's derived meshes and tissue engineered prostheses, with focus on its biocompatibility and technical innovations, especially for vaginal prolapse surgery.

INTRODUCTION AND OBJECTIVES: The increase of the intensity of urinary symptoms in late pregnancy and postpartum has been well documented by several authors, but their causes remain uncertain, partly because of its probable multifactor origin. There are also controversies whether the etiology of lower urinary tract symptoms during pregnancy is the same as postpartum and whether the method of delivery could influence the risk of onset of urinary symptoms. This study aimed to evaluate the urinary symptoms triggered during pregnancy and its evolution in the late puerperium, correlating them with the delivery method. MATERIALS AND METHODS: A longitudinal study was conducted, which included 75 primigravidae women, classified according to method of delivery as: (VD) vaginal delivery with right mediolateral episiotomy (n = 28); (CS) elective caesarean section (n = 26); and (EC) emergency caesarean section (n = 21). Urinary symptoms were assessed in the last trimester of pregnancy and at 45 days (± 10) of puerperium with validated versions for Portuguese language of the following questionnaires: International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form (ICIQ-UI SF) and the International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB). RESULTS: It was observed that frequency, urgency, nocturia and urge incontinence, triggered during pregnancy, decreased significantly in the postpartum period, regardless of the delivery method (p = 0.0001). However, symptoms related to urinary loss due to stress persisted after vaginal delivery (p = 0.0001). CONCLUSIONS: Urgency, frequency and nocturia triggered during pregnancy tend to disappear in the late postpartum period, regardless of the delivery method, but the symptoms related to urinary loss due to stress tend to persist in late postpartum period after vaginal delivery.

INTRODUCTION AND OBJECTIVES: The mini sling concept for stress urinary incontinence is an anatomical approach that involves placing a midurethral low-tension tape anchored to the obturator internus muscles bilaterally. They overcome the blind passage of long needles and all the related complications. There are many different devices available and because these are outpatient procedures, primary fixation plays an important role in the outcome. The objective is to evaluate the primary fixation of the various devices of attachment of the commercially available mini-slings through biomechanical tests. MATERIALS AND METHODS: A total of 45 Wistar rats were divided in 3 groups of 15 rats each. They underwent 5 subcutaneous implantation of different mini slings and one polipropilene mesh (control), as follows: TVT-Secur® (Gynecare, USA), Type 1 polypropylene mesh (control); Ophira Mini Sling System® (Promedon, Argentina), Tissue Fixation System® (TFS PTY, Australia), Zipper Sling® and "T device" (Prosurg, USA). The abdominal wall was removed on bloc at different times after implant for biomechanical evaluation, which consisted in application of unidirectional force to the extremity of the fixation system or mesh, until it was completely removed from the tissue using a tension meter (Nexygen 3.0 Universal Testing Machine - LLOYD Instruments). The force was measured in Newtons (N). RESULTS: There was significant difference in the resistance to extraction among the different fixation systems. At 7 days the Ophira Mini Sling System® presented the best fixation and "T dispositive" the worst. CONCLUSION: Ophira mini sling System® presented the best primary fixation at 7º, 14º and 30º days. The impact of this feature in the clinical setting needs to be verified.

PURPOSE: This prospective study was performed to achieve visualization of the reestablishment of anatomy after reconstructive surgery in the different pelvic compartments with non-absorbable radiopaque meshes, providing valuable anatomic information for surgeons implanting meshes. MATERIALS AND METHODS: A total of 30 female patients with stress urinary incontinence (SUI), anterior and posterior vaginal wall prolapse, or both underwent surgical repair using radiopaque meshes after written informed consent. Patients with SUI underwent five different surgeries. Patients with anterior vaginal prolapse underwent a procedure using a combined pre-pubic and transobturator mesh, and those with posterior vaginal prolapse underwent posterior slingplasty. Three-dimensional reconstruction using helical CT was performed four weeks postoperatively. RESULTS: In all cases, the mesh was clearly visualized. Transobturator slings were shown at the midurethra, and the anchoring tails perforated the obturator foramen at the safety region. Mini-slings were in the proper place, and computed angiography revealed that the anchoring system was away from the obturator vessels. In patients undergoing procedure for anterior vaginal prolapse, both pre-pubic armpit and obturator slings were clearly seen and the mesh was in the proper position, supporting the bladder base and occluding the distal part of the urogenital hiatus. Transcoccygeal sacropexy revealed indirectly a well-supported "neo rectovaginal fascia" and the anchoring tails at the level of ischial spines. CONCLUSION: Three-dimensional helical tomography images of the female pelvis using radiopaque meshes have a potential role in improving our understanding of pelvic floor reconstructive surgeries. These radiopaque meshes might be the basis of a new investigative methodology.

Objective: The creation of neo utero-sacral neoligaments, decribed by Petros, evolved into a new procedure allowing for the anatomical reconstruction of the three levels proposed by DeLancey. The aim of this study is evaluate the anatomical and functional outcomes of this minimally invasive procedure. Patients and method: From December 2004 to March 2007, a total of 34 patients with posterior defect grade III or higher underwent this procedure. The minimum follow up was 13 months Mean age was 63 years. The site of fixation was the Sacrospinous ligament. Surgical technique: The ischiorectal fossa is dissected. Next two small skin incisions are made 3 cm lateral and inferior to the center of the anus. A proper needle is introduced, vertically towards the sacrospinal ligament at the level of the ischial spine, guided by the surgeon index finger, 2 cm medially avoiding the Alcok canal. The armpit of the mesh is connected to the tip of the needle and brought to the perineal region. No site specific correction is made. Results: The cure rate was 94,7% and recurrence rate was 5,3%. No visceral, nerurovascular injuries were observed. The mesh exposure rate (less than 1 cm²) was (14.7%) and all patients were treated conservatively with no impact on the outcome. There were transient dyspareunia in 2 (11.8%) of the 17 sexually active patient and persistent in 1 case (5.9%). Conclusions: This procedure is an attractive minimally invasive alternative for the anatomical and functional reconstruction of the posterior and apical defects.

Objetivo: La creación de neoligamentos útero- sacros, según lo descripto por Petros, con el uso de malla sintética de polipropileno permite la corrección anatómica del prolapso posterior en los tres niveles propuestos por DeLancey. El objetivo de este estudio es evaluar los resultados anatómicos y funcionales de este método en la corrección del POP posterior. Pacientes y método: Desde diciembre del 2004 a marzo del 2007, 34 mujeres con edad media de 63 años fueron sometidas al procedimiento, siendo rectoceles grado III o mayores. El seguimento mínimo fué de 13 meses. Los puntos de fijación fueron el músculo íleococcígeo y el ligamento sacroespinoso. Técnica: Luego de la incisión de la mucosa de la pared vaginal posterior, la fosa ísquio-rectal es disecada. Dos pequeñas incisiones son hechas 3 cm lateral y 3 cm inferior al ano. La aguja se inserta verticalmente en dirección a la espina isquiática, guiado por el dedo indicador del cirujano hasta el ligamento sacroespinoso, 2 cm medialmente, evitando a lesión del canal de Alcock. Los brazos de la malla son conectados a la punta de la aguja, traccionando posteriormente de las agujas. No se realiza la correción sitio específica. El exceso de malla es recortado y esta se fija próxima al cuerpo perineal, quedando de esa forma extendida sobre la pared vaginal posterior. La mucosa vaginal se cierra en forma habitual. Resultados: Con el 94,7% de cura y recurrencia del 5,3%, no hubo lesión nerviosa, visceral o vascular. Cinco (14,7%) pacientes tuvieron exposición de la malla de menos de 1 cm² y fueron tratadas conservadoramente sin impacto en los resultados. Dos de las 17 sexualmente activas (11,8%) presentaron dispareunia transitoria, siendo prolongada en 1 solo caso (5,9%) Conclusión: Este procedimiento mínimamente invasivo es una alternativa atractiva para la reconstrucción anatómica y funcional de los defectos posteriores y apicales.

Objectives: Voiding dysfunction and urinary retention were frequent complications of sling. More recently synthetic supplies such as polypropylene mesh have been included in the armamentarium for sub urethral support. Methods: A prospective non randomized study was conducted. Sling procedure was performed in 436 consecutive patients with SUI. Patients were divided in groups according to mesh type, being 210 on autologous and 226 on synthetic. Patients were surveyed on voiding condition, continence and satisfaction. Surgical results were assessed according to Blaivas classification. Results were considered significant p<0.05. Results: Mean patient age was 48,4 years. Mean operative time for autologous sling was of 107,6 min versus 20,6min for synthetic. Mean hospitalization was 36h on autologous versus 24h on synthetic and mean follow up was 25 months. We found 87,1% and 92,9% of patients continent in autologous and synthetic group, respectively. Failure was presented by 7% in autologous and 4,8 % in synthetic group (p=0.1961). The global rate of BOO was of 4,5 % (20/436), when analysed by groups we found on autologous a rate of 8.5% (18/210), compared to 0.9% on synthetics (2/226) (p=0.000126). Conclusions: Autologous and synthetic slings presented comparable success rates, however BOO was more common among patients treated by autologous slings.

Introducción: Disfunción en el vaciamiento y retención urinaria son complicaciones frecuentes del cabestrillo. Recientemente se han incluido en el arsenal para el soporte sub-uretral, suministros sintéticos tales como la malla de polipropilenol. Métodos: Se llevó a cabo un Estudio prospectivo no aleatorizado. El procedimiento cabestrillo se realizó en 436 pacientes consecutivos con IUE (Incontinencia Urinaria de Esfuerzo). Las pacientes fueron divididas en grupos según el tipo de malla, en autólogos 210 y 226 sintéticos. Las pacientes fueron evaluadas en cuanto a condición de vaciamiento, continencia y satisfacción. Los resultados quirúrgicos fueron evaluados en función de la clasificación de Blaivas. Se consideró significativo p<0,05. Resultados: La media de edad fue 48,4 años. El tiempo medio operatorio para los Cabestrillo autólogos fue de 107,6 minutos frente a 20,6 min para el sintético. El promedio de hospitalización fue de 36 horas para autólogos frente a 24 horas para los sintéticos y la media de seguimiento fue de 25 meses. Se encontró 87,1% y 92,9% de las pacientes continentes en los grupos autólogos y sintéticos, respectivamente. Fallo en el procedimiento se presentó en un 7% en el grupo autólogo y 4,8% en el sintético (p=0,1961). La tasa global de obstrucción del tracto urinario inferior fue de 4,5% (20/436), cuando se analizó por grupos, encontramos en el grupo autólogo una tasa de 8,5% (18/210), en comparación con el 0,9% en el grupo sintético (2/226) (p=0,000126). Conclusiones: Cabestrillos autólogos y sintéticos presentan las tasas de éxito comparables, sin embargo la obstrucción del tracto urinario inferior fue más común entre las pacientes tratadas con fascias autólogas.

OBJETIVO: Avaliar a frequência de Sintomas Urinários Irritativos (SUI) três anos após o parto em mulheres previamente entrevistadas no terceiro trimestre da gestação e sua associação com a via de parto exclusiva, a paridade, a idade materna, o peso do RN, a realização da episiotomia e o uso de fórcipe. MÉTODOS: Das 340 mulheres, originalmente avaliadas no terceiro trimestre da gestação, 120 foram localizadas e entrevistadas por telefone, três anos após o parto, entre junho e outubro de 2006. Foi analisada a associação entre SUI e via exclusiva de parto (vaginalou cesáreo), paridade,idade materna, peso do recém-nascido, realização da episiotomia e uso de fórcipe. Os resultados foram avaliados por meio de estatística descritiva, teste Qui quadrado e cálculo da razão de prevalência (p< 0,05). RESULTADOS: O grupo de mulheres estudadas consistiu de primíparas (37,5%) e multíparas (62,5%). As 95 que tiveram via exclusiva de parto foram categorizadas em vaginal (53) e cesáreas (42). Não houve associação significativa entre a presença de SUI após o parto e a via de parto exclusiva e a paridade. Também não encontramos associação entre a presença de SUI e a idade materna (> 35) peso do recém-nascido (> 4000g), realização da episiotomia e uso de fórcipe. CONCLUSÃO: A via de parto e a paridade não foram fatores determinantes para a disfunção do trato urinário inferior após o parto, representada pelos sintomas urinários irritativos, tampouco, a idade materna, o peso do RN, a realização da episiotomia e o uso de fórcipe.

OBJECTIVE: This study intended to investigate the frequency of irritative bladder symptoms three years after delivery in women previously interviewed in the third trimester of pregnancy and its correlation to mode of delivery, parity, maternal age, birth weight, episiotomy and forceps. METHODS: From 340 women previously evaluated at the third trimester of pregnancy, 120 were interviewed three years after delivery, between June and October 2006. Correlation of postpartum irritative bladder symptoms and mode of delivery (exclusively vaginal or c-section), parity, maternal age, birth weight, episiotomy and forceps was analyzed. Associations between irritative bladder symptoms and obstetric parameters were assessed by the Fisher's exact test and Chi-square (p< 0.05). RESULTS: The study group consisted of 37.5% primiparous and 62.5% multiparous women. Mode of delivery was exclusively vaginal in 53 women and exclusively c-section in 42. No statistical difference was found between irritative bladder symptoms and mode of delivery and parity. No statistical difference was found between irritative symptoms and maternal age (> 35), birth weight (> 4000g), episiotomy and forceps. CONCLUSION: After childbirth, dysfunction of the lower urinary tract, characterized by irritative bladder symptoms, was not associated with mode of delivery, parity, maternal age, birth weight, episiotomy and forceps.

OBJECTIVE: Prospective study to objectively evaluate the benefits of pelvic floor strengthening exercises associated to biofeedback for the treatment of stress urinary incontinence. MATERIALS AND METHODS: Fourteen patients diagnosed with stress urinary incontinence (SUI) were selected for this study. All patients underwent a pelvic floor training associated to biofeedback for 12 consecutive weeks. Urodynamic tests, pad test and bladder diary were analyzed at the beginning of the study, at the end and after 3 months. The King's Health Questionnaire (KHQ) was applied before and after treatment to assess the impact in the quality of life. RESULTS: There was a significant reduction in the pad weight (from 14.21 g to 1 g), number of urinary leakage episodes (from 8.14 per day to 2.57 per day) and daytime frequency (from 7.93 per day to 5.85 per day). At urodynamics the authors observed a significant increase in Valsalva leak-point pressure (from 103.93 cm H2O to 139.14 cm H2O), cistometric capacity (from 249.29 mL to 336.43 mL, p = 0.0015) and bladder volume at first desire to void (from 145 mL to 215.71 mL). Those differences were kept during the first 3 months of follow up. The KHQ revealed significant differences except in the case of "general health perception", which covers health in general and not exclusively urinary incontinence. CONCLUSION: Treatment of SUI with pelvic floor exercises associated to biofeedback caused significant changes in the parameters analyzed, with maintenance of good results 3 months after treatment.

INTRODUCTION: SAFYREä is a readjustable and minimally invasive sling for the treatment of stress urinary incontinence (SUI). It is as a pubovaginal sling placed in the medial third of the urethra. The initial experience is described. MATERIALS AND METHODS: Forty-five patients (mean age = 59 years) underwent a SAFYREä implant to treat SUI. Physical examination and urodynamic study were performed before surgery. All patients presented symptoms of SUI and 20% also reported mild urgency. Approximately 60% of this group had a previously failed anti-incontinence procedure. Urethral hypermobility was diagnosed in 40% of the patients and intrinsic sphincter deficiency (ISD) in 60% of the cases. RESULTS: The average follow up period was 10 months. The mean operative time was 20 minutes. Dystopia repair was performed whenever necessary, during the same procedure. The average hospital stay was 24 hours. In 11% of the implants, bladder perforation occurred. During the postoperative period, 9 patients (20%) developed transient urgency symptoms. During the initial follow up period, 90% were found to be continent, 3% reported an improvement and 7% were unchanged. CONCLUSION: SAFYREä is a safe and quick procedure that allows postoperative readjustment. This technique may be an attractive alternative in the management of SUI, should the good result obtained so far prove to be long lasting.
