Hematoma retropúbico masivo posterior a TVT: enfrentamientos diferentes para una complicación infrecuente / Massive retropubic hematoma after TVT: different approaches for an uncommon complication

INTRODUCCIÓN: La TVT (tension-free vaginal tape) es una cirugía efectiva, pero no exenta de riesgos. Las complicaciones vasculares ocurren en un 0,9-1,7%; solo el 0,33% se presentan como hematoma masivo, en general asociado a la lesión de variante anatómica corona mortis (CM). OBJETIVO: Reportar tres tipos de manejo en pacientes con hematomas masivos después de cirugía para la incontinencia. MÉTODO: Revisión de casos de hematomas masivos tras TVT. Análisis de tres casos con diferente manejo. RESULTADOS: 1086 pacientes operadas en 10 años, 1% hematomas sintomáticos, 0,36% hematomas masivos. Se presentan tres casos. Caso 1: presenta inestabilidad hemodinámica sin respuesta a volumen ni vasoactivos, requirió laparotomía exploradora y se encontró un vaso sangrante retropúbico, compatible con CM, y un hematoma de 1000 cc. Caso 2: hipotensión que responde a volumen, asintomática al día siguiente de alta, reingresó 12 días después con caída de 6 puntos en la hemoglobina y la tomografía computarizada (TC) mostró un hematoma de 550 cc; recibió drenaje percutáneo. Caso 3: asintomática, alta el primer día posoperatorio, reingresa al quinto día con descenso de 4 puntos en la hemoglobina y la TC informa hematoma de 420 cc, que drena espontáneamente por vía vaginal. Todas las pacientes recibieron 14 días de antibióticos, y permanecieron continentes. CONCLUSIONES: Los hematomas retropúbicos masivos son una complicación poco frecuente. Su manejo considera la estabilización hemodinámica, el control del sangrado y el drenaje.

INTRODUCTION: TVT (tension-free vaginal tape) is an effective surgery, not without risks. Vascular complications occur in 0.9 to 1.7%, of which 0.33% present as massive hematoma, generally associated with injury of an anatomical variant, Corona Mortis (CM). OBJECTIVE: To report three types of management in patients with massive hematomas after anti-incontinence surgery. METHOD: Review of cases of massive hematomas after TVT surgery. Analysis of three cases with different management. RESULTS: 1086 patients operated in 10 years, 1% symptomatic hematomas, 0.36% massive. Three cases are presented. Case 1: hemodynamic instability without response to volume or vasoactive agents, required reoperation with exploratory laparotomy, a retropubic bleeding vessel, compatible with CM, and hematoma 1000 cc was found. Case 2: hypotension responds to volume, asymptomatic at next day in discharge conditions, she was readmitted 12 days later with falled 6-point in Hb, and CT showed hematoma 550 cc; she received percutaneous drainage. Case 3: asymptomatic, discharge on the first day after TVT, readmitted on the 5th day with falled 4-point in Hb, CT informed hematoma 420 cc, spontaneously drains vaginally. Patients received 14 days of antibiotics, remained continent. CONCLUSIONS: Massive retropubic hematomas are an infrequent complication, and management considers hemodynamic stabilization, bleeding control and drainage.

Síndrome compartimental bilateral de pierna tras posición de litotomía prolongada: presentación de un caso clínico / Bilateral leg compartment syndrome after prolonged lithotomy position: clinical case report

INTRODUCCIÓN: El síndrome compartimental es una complicación infrecuente pero severa que puede aparecer ante una posición de litotomía prolongada y el uso de perneras. OBJETIVO: Presentar un caso de síndrome compartimental bilateral tras posición de litotomía prolongada asociada con el uso de perneras. MATERIAL Y MÉTODOS: Paciente varón de 43 años sometido a una cirugía urológica en posición habitual de litotomía durante un periodo de 6 horas. A las 2 horas de finalizar la cirugía, el paciente presentó dolor intenso y endurecimiento de compartimento anterior y lateral de ambas piernas, junto con una elevación de la creatina quinasa sérica (valor inicial de 109 U/L que se elevó hasta 7.689 U/L a las 12 horas) y una imposibilidad para la flexión dorsal pasiva de ambos tobillos. El paciente no sentía dolor en el resto de los compartimentos. RESULTADOS: Ante la sospecha de un síndrome compartimental anterolateral, se realizó fasciotomía bilateral urgente, y se observó una disminución de la perfusión muscular y mejoría de la misma tras apertura de la fascia. Se realizaron curas periódicas cada 48 horas, y se observó viabilidad del tejido hasta su cierre definitivo a los 4 días. A las 2 semanas, el paciente presentó fatiga ligera para la deambulación sin ayuda, con tumefacción en el compartimento lateral de ambas piernas. A los 10 meses de evolución, el paciente caminaba sin ayuda y con función muscular completa. CONCLUSIONES: El conocimiento de la asociación del síndrome compartimental y la cirugía laparoscópica prolongada es esencial para un diagnóstico precoz y un tratamiento quirúrgico inmediato, para evitar graves secuelas. Los buenos resultados de nuestro paciente se deben a la rápida actuación, ya que normalmente se suele demorar. Para evitar su aparición o disminuir su incidencia, la posición de litotomía debería limitarse a aquellos momentos de la cirugía en los que sea imprescindible, modificando la posición de las piernas cada dos horas en caso de cirugías prolongadas, para prevenir dicha complicación.

Compartment syndrome is a rare but severe complication resulting from a prolonged lithotomy position and the use of leg loops. PURPOSE: To present a case of bilateral compartment syndrome after prolonged lithotomy position associated with the use of leg loops. METHODS: A 43-year-old man underwent urological surgery in the usual lithotomy position for a 6-hour period. Two hours after the end of the surgery, the patient presented severe pain and stiffening of the anterior and lateral compartments of both legs, elevated serum creatine kinase levels (the baseline value of 109 U/L increased to 7,689 U/L at 12 hours), and inability for passive dorsiflexion of both ankles. The patient reported no pain in the other compartments. RESULTS: Suspicion of an anterolateral compartment syndrome resulted in an urgent bilateral fasciotomy; muscle perfusion was decreased, and it improved after fascial opening. Dressings were changed every 48 hours, and tissue viability was observed until the final closure at 4 days. At two weeks, the patient presented slight fatigue when walking with no assistance, in addition to swelling in the lateral compartment of both legs. Ten months after surgery, the patient walked with no assistance and with complete muscle function. CONCLUSION: Knowledge of the association between compartment syndrome and prolonged laparoscopic surgery is essential for an early diagnosis and immediate surgical treatment to avoid serious sequelae. In our patient, the good outcomes resulted from quick action, since diagnosis is often delayed. Limiting the lithotomy position to those surgical moments in which it is essential and changing the position of the legs every 2 hours during prolonged procedures can reduce the occurrence and incidence of compartment syndrome, preventing this complication.

Complicaciones en posoperatorio inmediato de cirugía uretral anterior; ¿existe relación con la recaída? / Early complications in urethral anterior surgery; is there any relationship with recurrence?

INTRODUCCIÓN/OBJETIVO: La estrechez uretral puede causar síntomas miccionales, dolor, disfunción vesical y eyaculatoria. La tasa de complicaciones en uretroplastía anterior es baja. El principal objetivo es evaluar complicaciones del posoperatorio (pop) inmediato (dentro de los 30 días pop). El objetivo secundario es valorar la relación entre complicaciones y la tasa de recaída. MATERIALES Y MÉTODO: Se realizó una revisión retrospectiva de las uretroplastías anteriores realizadas entre octubre del 2012 y junio del 2017. Se valoró: reinternación, reingreso a cirugía, infarto agudo de miocardio, tromboembolismo de pulmón, trombosis venosa profunda, óbito, infecciones, dehiscencia de herida, hematomas, sangrados, etc. Se definió recaída a la necesidad de realizar cualquier instrumentación uretral secundaria a la uretroplastía. Las variables se analizaron estadísticamente con Chi square y Mann-Whitney U test. RESULTADOS: Se incluyeron 92 pacientes, con un seguimiento mínimo de 12 meses. Las edades fueron de 18 a 88 años (mediana, 61,5 años). En 58 pacientes, se utilizaron transferencia de tejidos (27 injertos y 31 colgajos). La longitud de la estrechez fue desde 1-15 cm (media, 3,25 cm). La iatrogénica (56%) fue la etiología más frecuente. 56 pacientes (63%) tenían tratamientos previos. La tasa de complicaciones pop inmediato fue del 32%, las infecciones fueron las más frecuentes. Según Clavien, se clasificaron: I: 40%; II: 47%; III: 10%; IV: 3%. Hubo 17 recaídas (18%), 13 dentro de los primeros 6 meses del pop. De los pacientes que presentaron complicaciones, recayó el 23%; solo 16% de los que no las presentaron (p: 0,4). Aquellos pacientes con complicaciones graves presentaron mayor tasa de recaída (p: 0,2). CONCLUSIÓN: La tasa de complicaciones pop inmediata de uretroplastía anterior fue de 32%; las infecciones fueron las más frecuentes. La mayoría fue Clavien I y II. La recaída fue mayor en aquellos pacientes que sufrieron complicaciones en pop inmediato.

INTRODUCCION/OBJECTIVE: Urethral stenosis can cause mictional symptoms, pain, bladder dysfunction and ejaculatory problems. Complications rate in anterior urethroplasty is low. Main objetive is to evaluate early post operatory complications Secondary objetive is to assess the relationship between complications and recurrence rate. MATERIALS AND METHODS: We performed a restrospective review of our anterior urethroplasty database between October 2012 and June 2017. We recorded: patients readmission, return to operating room, acute myocardial infarction, pulmonary embolism, deep venous thrombosis, death, infections, wound dehiscense, hematomas, bleedings, etc. We defined recurrence as any urethral instrumentation after urethroplasty. Variables were analyzed using Chi Square and Mann Whitney U test. RESULTS: 92 patients were included in the study with at least 12 months follow up. Age range was between 18-88 years. (median 61,5 years) Substitution urethroplasty were performed in 58 patients (grafts 27 and flaps 31) Urethral stenosis lenght range was between 1 and 15 cm (mean 3,25cm) Most frequent cause of urethral stenosis was iatrogenic (56%) 56 patients underwent previous treatment (63%) Complication rate in early post operative period was 32%, most of them infections. Clavien clasiffication: I: 40%; II: 47%; III: 10%; IV: 3%. There were 17 recurrences (18%), 13 during the first 6 months after surgery. 23 % of patients with complications had recurrence and only 16% of patients without, had recurrence (p:0,4) Patients with serious complications had greater recurrence rate (p: 0,2) CONCLUSION: Recurrence rate in early complications of anterior urethroplasty was 32%, most of them infections. Clavien I and II are the most frequent. Recurrence was greater in patients who suffered early complications

Emergency Surgery in Urology during the COVID-19 Pandemic

ABSTRACT Proposal: To highlight the indications for emergency surgery during the 2019 Coronavirus pandemic (COVID-19) that support recommendations published in midMarch 2020 by the American Confederation of Urology on its website. Materials and Methods: A bibliographic search was conducted in PubMed and Cochrane Library to perform a non-systematic review, using key words: Urology, Emergency and COVID-19, to determine recommendations for patients that should receive emergency care due to urological pathology. Results: The main recommendations and protocols in the management of different urological emergencies during the COVID-19 pandemic are reviewed and discussed. Conclusions: We are living a new condition with the COVID-19 pandemic, which obliges urologists to conform to the guidelines that appear on a daily basis formulated by multidisciplinary surgical groups to manage urological emergencies. Consequently, in this time of health crisis, we must adapt to the resources available, implementing all biosecurity measures to protect patients and all health personnel who are in charge of patient management.

Assessment of long term outcomes after buccal mucosal graft urethroplasty: the impact of chronic kidney disease

ABSTRACT Objectives To compare and assess various outcomes and success of buccal mucosal graft urethroplasty (BMGU) in patients with CKD versus patients having normal renal function. Material and Methods This was a retrospective, single centre study, during period 2013 to 2017. Patients were grouped into two groups. Group 1 had patients with estimated Glomerular Filtration Rate (eGFR)>60mL/min/1.73m2 while group 2 had patients with eGFR <60mL/min/1.73m2. eGFR was calculated according to the MDRD equation. The two groups were compared with regard to various outcomes like length, location of stricture, technique of graft placement, intra-operative blood loss (haemoglobin drop), duration of hospital stay, post-operative complications and recurrence. Results A total of 223 patients were included in study with group 1 had 130 patients and group 2 had 93 patients. Mean age of patients with CKD were higher (47.49 years versus 29.13 years). The mean follow-up period was comparable between both groups (23.29 months and 22.54 months respectively). Patients with CKD had more post-operative Clavien Grade 2 or higher complications (p=0.01) and a greater recurrence rates (p<0.001) than in non-CKD patients. On multivariate analysis, age and CKD status was significant predictor of urethroplasty success (p=0.004) (OR= 14.98 (1.952-114.94, 95% CI). Conclusions CKD patients are more prone to post-operative complications in terms of wound infection, graft uptake and graft failure and higher recurrence rates following BMGU.

Intraoperative serious complications of laparoscopic urological surgeries: a single institute experience of 4, 380 procedures

ABSTRACT This study aimed to share a single institute experience of 4,380 procedures about in-traoperative serious complications of laparoscopic urological surgeries. From January 2005 to December 2013, 4,380 cases of laparoscopic urological surgeries were recruited in our department. The distribution, incidence, and characteristics of intraoperative serious complications were retrospectively sorted out and analyzed. The surgeries were divided into three groups: very difficult (VD), difficult (D), and easy (E). The com¬plication at Satava class II was defined to be serious. One hundred thirty one cases with intraoperative serious complications were found (3.0%). The incidence of these complications was significantly increased along with the difficulty of the surgeries (P<0.05). The highest morbidity of serious complication belonged to total cystectomy with a ratio of about 17% as compared with other surgeries (P<0.05). The types of these complications included small vascular injury demanding blood transfusion (101 cases, 77.1%), large vascular (venous and artery) injury (16 cases), hypercapnia & acidosis (8 cases), and organ injury (6 cases). The cases of conversion to open surgery were 37 (≤1%). There was no significant difference in the rates of conversion to open surgery among the three groups (P>0.05). The overall tendency of the intraoperative serious complications was decreasing with the time from 2005 to 2013. In conclusion, through standardized training including improving the surgical technique, being familiar with the anatomic relationship, and constantly summarizing the experience and lessons, laparoscopic surgery could be safe and effective with not only minimal invasion but also few complications.

Bilateral compartment syndrome of the lower limbs after urological surgery in the lithotomy position: a clinical case / Síndrome compartimental dos membros inferiores após cirurgia urológica na posição de litotomia: um relato de caso

Acute compartment syndrome of the lower extremities after urological surgery in the lithotomy position is a rare but potentially devastating clinical and medicolegal problem. We report the case of a 67-year-old male who underwent laparoscopic prostatectomy surgery to treat cancer, spending 180 minutes in surgery. Postoperatively, the patient developed acute compartment syndrome of both legs, needing emergency bilateral four-compartment fasciotomies, with repeated returns to the operating room for second-look procedures. The patient also exhibited delayed wound closure. He regained full function within 6 months, returning to unimpaired baseline activity levels. This report aims to highlight the importance of preoperative awareness of this severe complication which, in conjunction with early recognition and immediate surgical management, may mitigate long-term adverse sequelae and improve postoperative outcomes

A síndrome compartimental aguda dos membros inferiores após cirurgia urológica na posição de litotomia é um problema clínico e médico-legal raro, mas potencialmente devastador. Reportamos o caso de um homem de 67 anos submetido a uma prostatectomia laparoscópica por câncer. A cirurgia durou 180 min. No pós-operatório, o paciente desenvolveu síndrome compartimental aguda de ambos os membros inferiores, necessitando de fasciotomias de urgência, com retornos repetidos à sala de cirurgia para procedimentos adicionais. O paciente também apresentou fechamento tardio da ferida. Ele recuperou a função completa dentro de 6 meses e retornou a um nível de atividade basal irrestrito. Este artigo tem a importância de ressaltar a consciência pré-operatória desta grave complicação que, em conjunto com o reconhecimento precoce e o tratamento cirúrgico imediato, pode mitigar sequelas adversas em longo prazo e melhorar os resultados pós-operatórios

Update on complications of synthetic suburethral slings

ABSTRACT Synthetic suburethral slings have become the most widely used technique for the surgical treatment of stress urinary incontinence. Despite its high success rates, significant complications have been reported including bleeding, urethral or bladder injury, urethral or bladder mesh erosion, intestinal perforation, vaginal extrusion of mesh, urinary tract infection, pain, urinary urgency and bladder outlet obstruction. Recent warnings from important regulatory agencies worldwide concerning safety issues of the use of mesh for urogynecological reconstruction have had a strong impact on patients as well as surgeons and manufacturers. In this paper, we reviewed the literature regarding surgical morbidity associated with synthetic suburethral slings.

Complications after bladder augmentation in children

PURPOSE : Bladder augmentation is an effective surgical procedure for increasing bladder capacity and reducing pressure on the urinary system. It is indicated for patients with anomalies such as spina bifida, myelomeningocele, urethral valve and bladder exstrophy, who progress with low tolerance of medication. CASES : This was a retrospective study conducted on pediatric patients submitted to bladder augmentation from 2000 to 2011. RESULTS : 34 patients aged 4 to 17 years were submitted to bladder augmentation, 30 of them with an ileal loop and 4 with a ureter.A continent urinary shunt was performed in 16 patients, the Mitrofanoff conduit was associated in 15, and the Macedo technique was used in one. Mean follow-up was 34.35 months (1 to 122 months). Mean creatinine was 1.5 ng/ml (0.4 to 7.5 ng/ml) preoperatively and 1.78 ng/ml postoperatively. Three patients required a renal transplant during follow-up. There was improvement or resolution of vesicoureteral reflux in 83.5% of the kidneys on the right and in 75% on the left. Bladder capacity increased, on average, from 152.5 ml to 410 ml. The main complications were vesical lithiasis in 3 patients and conduit perforation in one. CONCLUSION : Bladder augmentation showed good results in this series, preserving renal function in most of the patients.

Comparison between the retropubic and transobturator approaches in the treatment of female stress urinary incontinence: a systematic review and meta-analysis of effectiveness and complications

Objective This study aimed to compare the effectiveness and complications between the retropubic and transobturator approaches for the treatment of female stress urinary incontinence (SUI) by conducting a systematic review. Materials and Methods We selected all randomized controlled trials (RCTs) that compared retropubic and transobturator sling placements for treatment of SUI. We estimated pooled odds ratios and 95% confidence intervals for intraoperative and postoperative outcomes and complications. Results Six hundred twelve studies that compared retropubic and transobturator approaches to midurethral sling placement were identified, of which 16 were included in our research. Our study was based on results from 2646 women. We performed a subgroup analysis to compare outcomes and complications between the two approaches. The evidence to support the superior approach that leads to better objective/subjective cure rate was insufficient. The transobturator approach was associated with lower risks of bladder perforation (odds ratio (OR) 0.17, 95% confidence interval (CI) 0.09-0.32), retropubic/vaginal hematoma (OR 0.32, 95% CI 0.16-0.63), and long-term voiding dysfunction (OR 0.32, 95% CI 0.17-0.61). However, the risk of thigh/groin pain seemed higher in the transobturator group (OR 2.53, 95% CI 1.72-3.72). We found no statistically significant differences in the risks of other complications between the two approaches. Conclusions This meta-analysis shows analogical objective and subjective cure rates between the retropubic and transobturator approaches to midurethral sling placement. The transobturator approach was associated with lower risks of several complications. However, good-quality studies with long-term follow-ups are warranted for further research. .

The cumulative analgesic consumption score (CACS): evaluation of a new score to describe postsurgical analgesic consumption as a surrogate parameter for postoperative pain and invasiveness of surgical procedures

Objective To validate and evaluate the applicability of a new score to describe postsurgical analgesic consumption in urological and surgical patients across different categories of pain medications and the invasiveness of medical interventions. Materials and Methods The cumulative analgesic consumption score (CACS) was determined for two cohorts of patients split into three groups with surgeries involving clinically distinct levels of invasiveness (n = 2 x 60). Nonparametric statistical analyses were performed to determine differences between the CACS among the different groups and to assess the correlation between CACS and numeric rating scale (NRS) values for pain intensity. Results The score was determined for postoperative days 1 and 2 and revealed median scores of 0 (0-11), 3 (0-22) and 10 (6-17) for UA (urological patients from group A), UB (group B) and UC (group C), respectively, and 4 (0-20), 8 (0-38) and 17 (7-68) for SA (surgical patients from group A, SB (group B) and SC (group C), respectively. CACS enabled reliable differentiation between groups involving different levels of invasiveness (p < 0.001). CACS and peak NRS values showed variable degrees of correlation, as expressed by levels of significance ranging from p < 0.001 to p = 0.34 (NS). Conclusions The CACS is a valid and easily applicable tool to describe postsurgical analgesic consumption in urological and surgical patients. It can be used as a surrogate parameter to assess postsurgical pain and the invasiveness of surgical procedures. These aspects may be measured to compare surgical procedures, in both clinical trials and clinical practice settings. .

Cirugía urológica en pacientes de 80 años y más: ¿es la edad un factor de riesgo para el desarrollo de complicaciones postoperatorias? / Urological surgery in patients 80 years and older: is age a risk factor for the development of postoperative complications?

La expectativa de vida ha ido aumentando en Chile y en el mundo, lo que ha causado un gran impacto a nivel del número de cirugías que se realiza en la población añosa. El objetivo de este trabajo es describir la experiencia de nuestro centro en cirugías urológicas en pacientes mayores de 80 años y analizar que factores aumentan el riesgo de complicaciones postquirúrgicas.Materiales y método: Análisis retrospectivo de 138 cirugías urológicas realizadas en 120 pacientes mayores de 80 años, durante los años 2000 a 2012. Se obtuvo información sociodemográfica, riesgo quirúrgico (ASA), tipo y duración de cirugía realizada, complicaciones post-operatorias (escala de Clavien) y tiempo de hospitalización. Los datos obtenidos fueron analizados mediante el programa SPSS v17. Se realizó análisis multivariado y se estableció el riesgo relativo para el desarrollo de complicaciones. Se consideró signi ficativo p<0,05. Resultado: La edad promedio de los pacientes fue de 84+/-3.7 años, 86.2 por ciento fueron hombres. El 96.7 por ciento presentaba algún tipo de comorbilidad, con predominio de hipertensión arterial (60,84 por ciento) y diabetes mellitus tipo 2 (24,16 por ciento). La mayoría de las intervenciones fue de complejidad intermedia (77.27 por ciento), donde la anestesia regional (56,8 por ciento) y la vía endo urológica (84,78 por ciento) fueron las más utilizadas, con un tiempo operatorio promedio de 62+/-52.4 minutos. El riesgo quirúrgico prevalente fue ASA2 (62.7 por ciento). El promedio de hospitalización fue de 2,8+/-2.7 días. El 15.21 por ciento de los pacientes presentó algún tipo de complicación, con predominio de clasifi cación tipo 1 de Clavien (38 por ciento). En el análisis multivariado se evidenció como factores de riesgo signi ficativos para complicaciones, edad mayor a 90 años (p=0.03), presencia de insu ciencia renal (p=0.01), portar 4 o más comorbilidades (p=0.04), cirugía mayor a 3 horas (p=0.03) y tener riesgo quirúrgico ASA3 (p=0.04)...

Life expectancy has been increasing in Chile and in the World. This has caused a great impact over the number of surgeries being performed in the elderly population. The aim of this paper is to describe the experience of our center in urological surgery in patients older than 80 years and analyze which factors increase the risk of postoperative complications.Materials and methods: Retrospective analysis of 138 urological surgeries performed in 120 patients older than 80 years, during the years 2000-2012. Sociodemographic information, surgical risk (ASA), type and duration of surgery, postoperative complications (Clavien scale) and length of hospitalization was obtained. The data were analyzed using SPSS v17. Multivariate analysis was performed and the relative risk for developing complications was established. Signi cance was p <0.05. Average age of the patients was 84 +/- 3.7 years, 86.2percentwere men. The 96.7 percenct had some kind of comorbidity, with prevalence of hypertension (60.84 percent) and diabetes mellitus type 2 (24.16 percent). Most of the interventions was of intermediate complexity (77.27percent), where regional anesthesia (56.8 percent) and endourological aproach (84.78 percent) were the most used, with average operative time of 62 +/- 52.4 minutes. Most common Surgical risk was ASA2 (62.7 percent). Average hospital stay was 2.8 +/- 2.7 days. 15.21 percent of patients had some type of complication, with a predominance of type 1 Clavien classication (38 percent). The multivariate analysis showed signi cant risk factors for complications: age greater than 90 years (p = 0.03), renal failure (p = 0.01), carrying 4 or more comorbidities (p = 0.04), surgery Langer than 3 hours (p = 0.03) and ASA3 surgical risk (p =.04). No mortality was reported in our series. In this study, although most of our patients underwent endourological procedures, we evidence that surgery in patients older than 80 years is feasible...

Arc-to-arc mini-sling 1999: a critical analysis of concept and technology

PURPOSE: The aim of this study was to critically review the Arc-to-Arc mini-sling (Palma's technique) a less invasive mid-urethral sling using bovine pericardium as the sling material. MATERIALS AND METHODS: The Arc-to-Arc mini-sling, using bovine pericardium, was the first published report of a mini-sling, in 1999. The technique was identical to the "tension-free tape" operation, midline incision and dissection of the urethra. The ATFP (white line) was identified by blunt dissection, and the mini-sling was sutured to the tendinous arc on both sides with 2 polypropylene 00 sutures. RESULTS: The initial results were encouraging, with 9/10 patients cured at the 6 weeks post-operative visit. However, infection and extrusion of the mini-sling resulted in sling extrusion and removal, with 5 patients remaining cured at 12 months. CONCLUSION: The Arc-to-Arc mini-sling was a good concept, but failed because of the poor technology available at that time. Further research using new materials and better technology has led to new and safer alternatives for the management of stress urinary incontinence.

Lesión diafragmática durante la laparoscopia urológica transperitoneal / Diaphragmatic injury during transperitoneal urological laparoscopic surgery

Introduction: Capnothorax is a rare complication of urologic laparoscopy. However with the increasing use of this technique in a variety of urological procedures, this rare complication is a potential risk. Material and Methods: We analyzed a total of 786 urological procedures performed by transperitoneal laparoscopy in our center. All procedures were performed by the same surgeon: 213 adrenalectomy, 181 simple nephrectomies, 143 lymphadenectomies, 118 radical nephrectomies, 107 partial nephrectomies and 24 nephroure-terectomy. Results: A total of 6 patients (0.7 percent) present diaphragmatic lesions. The diaphragmatic repair was performed totally intracorporeal. One patient required the placement of a pleural drainage. No patient presented complications associated with diaphragmatic injury. Conclusion: Repair of diaphragmatic injury during transperitoneal laparoscopy can be performed successfully by this route. This technique is feasible, reproducible and reliable. This is the largest series reported by a single center.

Introducción: El capnotórax es una complicación infrecuente de la laparoscopía urológica. No obstante, con el uso cada vez mayor de esta técnica en una gran variedad de procedimientos urológicos, esta infrecuente complicación se presenta como un riesgo potencial. Material y Métodos: Se analizaron un total de 786 procedimientos urológicos realizados en forma laparoscópica por vía transperitoneal en nuestro centro. Todos los procedimientos fueron realizados por el mismo cirujano: 213 adrenalectomías, 181 nefrectomías simples, 143 linfadenectomías, 118 nefrectomías radicales, 107 nefrectomías parciales y 24 nefroureterectomías. Resultados: Un total de 6 pacientes (0,7 por ciento) presentaron lesiones diafragmáticas. La reparación diafragmática fue efectuada totalmente en forma intracorpórea. Un solo paciente requirió de la colocación de un drenaje pleural. Ningún paciente presentó complicaciones asociadas a la lesión diafragmática. Conclusión: La reparación de las lesiones diafragmáticas ocurridas durante la laparoscopía transperitoneal puede ser efectuada exitosamente por esta misma vía. Esta técnica es factible, reproducible y confiable. Esta es la serie más grande reportada por un solo centro.

"Sling" retropúbico e transobturatório no tratamento da incontinênca urinária de esforço: [revisão] / Retropubic and transobturator sling in treatment of stress urinary incontinence: [review]

OBJETIVO: Comparar resultados das técnicas de "sling" retropúbico e transobturador para o tratamento de mulheres com incontinência urinária de esforço (IUE). MÉTODOS: Foram randomizadas 30 pacientes, sendo que 20 se submeteram ao sling retropúbico e 10 ao transobturador. As pacientes foram avaliadas antes e após o tratamento com um, seis e 12 meses, por meio de história clínica, exame físico, questionário de qualidade de vida ("King's Health Questionnaire"), teste do absorvente e avaliação urodinâmica. Os grupos foram homogêneos no pré-operatório. RESULTADOS: Houve melhora significante na avaliação da qualidade de vida em ambos os grupos após a terapêutica, sem diferença entre os grupos. Houve diminuição no peso do absorvente para os dois grupos. As taxas de cura pela avaliação urodinâmica em 12 meses foram de 84,2 por cento para o grupo transobturador e 88,8 por cento para o retropúbico. Da mesma forma, a cura subjetiva foi de 85 por cento e 88,8 por cento, respectivamente. Não observamos diferenças entre os grupos consoante as complicações. CONCLUSÃO: As cirurgias deste sling, pelas vias retropúbica e transobturadora, foram eficazes para o tratamento de mulheres com IUE, no seguimento de 12 meses. Observamos elevada taxa de cura e melhora da qualidade de vida com baixos índices de complicações.

OBJECTIVE: The aim of this study was to compare results of retropubic and transobturator sling for surgical treatment of female stress urinary incontinence (SUI). METHODS: Thirty randomized patients with SUI were divided in two groups, twenty who underwent the transobturator sling and ten the retropubic sling procedure. .Patients were assessed before and after one, six and twelve months of treatment by clinical history, physical examination, quality of life questionnaire (King's Health Questionnaire), pad test and urodynamic parameters. At preoperative both groups were homogenous. RESULTS: One year after surgery, incontinence and quality of life questionnaire parameters had improved significantly in both groups and there was no difference between them. There was significant reduction in the pad test in both groups. Concerning urodynamic evaluation, one year after surgery cure rates were 84.2 percent for the transobturator group and 88.8 percent for the retropubic,. Subjective cure rate was 85 percent in the transobturator group and 88.8 percent in the retropubic. No statistical difference was found in complications rates. CONCLUSION: Retropubic and transobturator slings were effective in treatment of female SUI at one-year follow-up. Both techniques had significant cure rates and improved the quality of life with few complications.

Does vaginal anti-incontinence surgery affect sexual satisfaction? A comparison of TVT and Burch-colposuspension

OBJECTIVE: To evaluate the sexual satisfaction rates of women who underwent tension-free vaginal tape (TVT) procedure for stress urinary incontinence and compare it with the results of Burch-colposuspension. MATERIALS AND METHODS: A self-administered questionnaire was given to 81 patients who had undergone TVT or Burch-colposuspension at our institution to determine sexual satisfaction rates and reasons for dissatisfaction. Forty-seven patients in TVT group and 22 patients in Burch-colposuspension group were considered eligible for the study. The mean follow-up period and age of patients in TVT and Burch-colposuspension groups were 34 months, 51.5 years and 89 months, 52.9 years, respectively. The difference between the ages in the two groups was not statistically significant, while the difference between mean follow-up periods was significant (p = 0.000). RESULTS: When evaluating sexual satisfaction, 73 percent in the TVT group and 86 percent in the Burch-colposuspension group did not report any difference in sexual satisfaction following surgery, while in the TVT group, 23 percent expressed negative and 4 percent positive changes, and in the Burch-colposuspension group 9 percent expressed negative and 5 percent positive post surgical changes. The differences in sexual satisfaction rates between the two groups were not considered significant. The majority (54 percent) of those who expressed a negative change suffered from dyspareunia. CONCLUSIONS: Although sexual satisfaction seems to be more adversely affected by TVT compared to Burch-colposuspension, the difference was not statistically significant. Further studies are required concerning different anti-incontinence techniques in order to arrive at more precise conclusions.

Fiebre postoperatoria en cirugía ortopédica y urológica / Postoperative fever in orthopedic and urologic surgery

La incidencia de fiebre en el postoperatorio varía ampliamente. En la cirugía limpia y la limpia-contaminada, la fiebre no infecciosa es más frecuente que la infecciosa. Fueron estudiados prospectivamente 303 pacientes operados en forma programada de cirugía ortopédica y urológica. Se investigó la incidencia de fiebre postoperatoria, su etiología, la relación entre el momento de su aparición y su origen y la utilidad del pedido empírico de estudios para determinar infección postoperatoria. El 14% (42/303) de los pacientes tuvieron fiebre postoperatoria. En el 81% (34/42) su etiología fue no infecciosa y en el 19% (8/42) infecciosa. Su origen fue siempre no infeccioso dentro de las primeras 48 horas del postoperatorio (p<0.001). A 19 pacientes con fiebre después de las 48 horas y examen clínico normal, se les realizó radiografía de tórax, hemocultivos (2) y cultivo de orina. Las radiografías de tórax fueron normales en todos los casos, fueron positivos 4 urocultivos (21%, IC 95%: 6-45) y un hemocultivo (5%, IC 95%: 0.1-26). Siete pacientes tuvieron infecciones postoperatorias sin fiebre. La causa de fiebre postoperatoria más frecuente fue no infecciosa, causada por respuesta normal inflamatoria al trauma quirúrgico. La realización de estudios de rutina en pacientes con examen clínico normal y fiebre posterior a las 48 horas, de acuerdo a lo observado en este estudio, no permite sacar conclusiones definitivas. El diagnóstico de las infecciones postoperatorias se basó en el seguimiento clínico- quirúrgico y en la interpretación de los síntomas y signos del paciente.

Post-operative fever incidence varies widely. In clean and clean-contaminated surgery the non-infectious fever is more frequent than the infectious fever. We performed a prospective study including 303 patients who underwent orthopedic and urologic elective surgery. The aims of our study were to investigate the incidence of post-operative fever, its etiology, the relationship between time of onset and the etiology, and the usefulness of extensive fever work-up to determine post-operative infection. The incidence of post-operative fever was 14% (42/303) of which 81% (34/42) was noninfectious and 19% (8/42) was infectious. The etiology of the fever in the first 48 hours after surgery was always non-infectious (p<0.001). An extensive fever work-up was performed in patients who presented fever only after the initial 48 hours of surgery with normal physical examination (n=19) consisting of chest x-ray, blood (2) and urine cultures. The chest x-ray was normal in all the patients, the urine cultures were positive in four cases (21%, IC 95%: 6-45) and the blood cultures in only one case (5%, IC 95%: 0.1-26). Seven patients had post-operative infections without fever as a clinical sign. The most frequently observed etiology of post-operative fever was non-infectious, related to the normal inflammatory host response to surgery. Based on the present results, the extensive fever work-up performed to investigate post-operative infection does not seem to be a useful tool. The diagnosis of post-operative infection was based on clinical follow up and the correct interpretation of the patient's symptoms and signs.

Resultados del Tension Free Vaginal tape (TVT) en el manejo quirúrgico de las recidivas post cirugía de Burch / The results of tension free vaginal tape after Burch's technique failure

La técnica de Burch es una de las que muestra mejores resultados a largo plazo en el tratamiento de la Incontinencia Urinaria de Esfuerzo (IOE), sin embargo también presenta recidivas. El principio básico de la uretropexia de Burch es subir el cuello vesical a una posición intrabdominal retropúbica. Si este principio no funciona deben considerarse soluciones quirúrgicas basadas en otros principios fisiopatológicos para una segunda cirugía, como es el TVT. Nuestro objetivo es evaluar los resultados del TVT en pacientes recidivadas después de cirugía de Burch, para ello realizamos una revisión retrospectiva de estas pacientes que fueron operadas por segunda vez con técnica de TVT. De 129 pacientes sometidas a TVT en nuestro Servicio, 17 presentaban el antecedente de recidiva de IOE después de cirugía de Burch. El promedio de edad fue de 56,3 años. El TVT se realizó en promedio 7,75 (3 - 13) años después del Burch. El 100 por ciento de las pacientes se mantiene sin IOE después de 49,7 (2 - 84) meses de seguimiento. No tenemos pacientes con perforación vesical ni retención de orina. En 4 (23,5 por ciento) se desarrolló urgencia de Novo. Una paciente presentó erosión que cerró espontáneamente. El TVT ha demostrado en nuestras pacientes ser una excelente alternativa para tratar las recidivas del Burch, pudiendo explicarse ya que la uretra media donde debe colocarse la malla es un área quirúrgicamente virgen y porque los mecanismos para evitar la pérdida de orina son distintos en las dos técnicas.

In most published series Burch colpocystourethropexy suggest an objective success rate for primarysurgery of between 80 percent and 90 percent. The aim of our study is to evaluate TVT as treatment after Burch failure. We evaluated retrospectively 129 TVT procedures at our institution between August 2000 and August 2007. We identified 17 patients who underwent a TVT procedure for recurrent stress urinary incontinence after Burch surgery. The mean age of the patient was 56.3 years. Mean follow-up was49.7 months (range 2 to 84). TVT was performed in average 7.75 years (range 3 to13) after Burch surgery. All the patients were considered cured. Our series didn’t have immediate complications defined as bladder or bowel perforation or postoperative urinary retention. We had one patient (5.9 percent) with vaginal erosion treated successfully with supportive measures. De novo urgency occurred in 23,4 percent(4 patients). According to our data, TVT shows good outcome in the treatment of Burch failure. TVT is a safe, effective, and minimally invasive option. We believe that clinical success is achieved because the mesh is in a different area from Burch colpocystourethropexy and different continence mechanismsare involved.
