ABSTRACT

INTRODUCTION: Given the fragility of reusable ureterorenoscopes, many single use instruments have appeared on the market. Unfortunately, reuse of these scopes occurs in undeveloped countries in order to cut costs. This raises safety concerns for the patient.The aim of this article was to macroscopically evaluate the changes that single use flexible ureterorenoscopes (su-fURS) suffer after a retrograde intrarenal surgery (RIRS), and to compare them to reusable fURS. MATERIAL AND METHODS: Pre and post-operative images of the instruments used in 23 RIRS were obtained. All the cases had renal calculi of the inferior calix between 10-15 mm, and all of them were treated with Holmium laser. The ureterorenoscopes used were: Storz® Flex X2, Storz® Flex XC, Pusen® 3022, OTU® Wiscope, AnQIng® Innovex and Boston Scientific® LithoVue. Qualitative comparisons of these were made. RESULTS: After su-fURS usage, significant damage was observed, especially on the distal tip. Deflection was not compromised. Reusable fURS did not sustain any damage after their use. CONCLUSIONS: fURS are delicate equipment, especially if they are of single use. The considerable damage sustained by single use scopes could mean that reuse of these instruments is dangerous and should be avoided.

ABSTRACT

Low dose rate brachytherapy (LDR-Br) with radioactive isotopes is a curative treatment and has shown to be comparable for the management of localized prostate cancer (PCa) to more conventional treatments such as radical prostatectomy or external beam radiotherapy, but with fewer side effects. The aim of this study is to show the global, specific and biochemical recurrence-free survival in 193 patients undergoing low dose rate Brachytherapy with permanent implants with iodine 125 and analyze the quality of life impact. 193 patients with localized PCa were consecutively treated over a period of 10 years (2005-2015). All of them were followed up on levels of prostate specific antigen (PSA) and 68 of them completed a quality of life survey. The average age was 62.8 years and the average PSA was 6.4 ng/dl at the time of Br. 29.5% of patients were classified as intermediate risk, with a Gleason score sum of 7 and/or a PSA between 10 and 20 ng/dl. Mean follow-up was 64.2 months; overall, specific and biochemical recurrence-free survival were 92.8%, 99.0% and 90.2% respectively. The most significant changes in the quality of life recorded were urinary incontinence, urinary and bowel irritative symptoms, in the first 6 months after brachytherapy. Sexual function shows significant changes but all with favorable response using phosphodiesterase inhibitors. This series of patients with PCa shows similar biochemical free survival rates BFSR in low risk patients to external beam radiotherapy and radical prostatectomy, but better BFSR in intermediate risk patients. The impact in the quality of life was significant in urinary incontinence, urinary irritate symptoms, and sexual function, but they were transitory with the exception of sexual function.

ABSTRACT

La braquiterapia LDR (low-doserate brachytherapy) (Br LDR) con isotopos radioactivos es un tratamiento curativo para el cáncer de próstata (CaP) localizado con resultados similares a tratamientos más convencionales como la prostatectomía radical o radioterapia externa, pero con menos efectos colaterales de acuerdo a lo publicado en algunas series. El objetivo de este trabajo es comunicar la sobrevida global, específica y libre de recidiva bioquímica en 193 pacientes que padecen de CaP localizado sometidos a Br de baja tasa de dosis con implantes permanentes de yodo 125. Como objetivo secundario analizar el impacto en la calidad de vida. El análisis se realizó en pacientes que padecen CaP localizado y que fueron tratados en un período de 10 años (2005-2015). A todos se les efectuó un seguimiento con niveles de antígeno prostático específico (PSA) y a 68 pacientes se les aplicó encuesta de calidad de vida. El promedio de edad fue de 62,8 años y el PSA promedio al momento del implante fue de 6,4 ng/dl. El 29,5% de los pacientes era de riesgo intermedio, con un puntaje Gleason 7 y/o un PSA entre 10 y 20 ng/dl. La media de seguimiento fue de 64,2 meses y la supervivencia global, específica y tasa libre de recidiva bioquímica (TLRB) fue de 92,8%, 99,0% y 90,2% respectivamente. Los cambios más significativos en la calidad de vida fueron en cuanto a incontinencia urinaria, síntomas de llenado/vaciado vesical e intestinales durante los primeros 6 meses desde la braquiterapia. En la función sexual se observaron cambios negativos significativos pero con respuesta favorable a distintas dosis de inhibidores de la fosfodiesterasa. Nuestra serie muestra TSLRB similares a los obtenidos en pacientes de bajo riesgo tratados con radioterapia externa o prostatectomía radical pero mejores TSLRP en pacientes de riesgo intermedio. El impacto en la calidad de vida fue significativo en los ítems de incontinencia de orina síntomas de llenado/vaciado vesical y función sexual, estos son transitorios a excepción de la función sexual (AU)

ABSTRACT

La vasectomía es un método simple, seguroy efectivo de control de fertilidad que tiene múltiples ventajas comparativas respecto a la ligadura tubaria. A pesar de esto, continúa representando sólo un pequeño porcentaje de las esterilizaciones efectuadas en nuestro país.El costo del procedimiento y el temor a la cirugía siguen siendo algunas de las barreras que impiden una mayor realización y aceptación del procedimiento. Estas aprehensiones podrían ser evitadas a través del uso de la técnica de vasectomía sin bisturí - sin aguja con el uso del dispositivo Madajet. El equipo Madajet es un aparato mecánico que permite inyectar un volumen fijo de 0,1 cc de anestésico local, con una penetración del liquido a 4-5 mm de la superficie epitelial, generando una pápula de 5-6 mm de diámetro que evita la distensión tisular producida por la inyección del anestésico con aguja.AU


Vasectomy is a simple, safe and effective fertility control method that has multiple comparative advantages over tubal ligation. Despite this, it continues to represent only a small percentage of the sterilizations carried out in our country. The cost of the procedure and the fear of surgery continue to be some of the barriers that prevent further implementation and acceptance of the procedure. These shortcomings could be avoided by using the no-scalpel needle-less technique incorporating the Madajet device. The Madajet device is a mechanical device that allows the injection of a fixed volume of 0.1 cc of local anesthetic, with a penetration of the fluid to 4-5 mm of the epithelial surface, generating a papule 5-6 mm in diameter that avoids the Tissue distention produced by injection of anesthetic with needle.AU

ABSTRACT

El bloqueo nervioso periprostático (BNPP) con lidocaína provee buena analgesia para la biopsia transrectal ecoguiada. Sin embargo la introducción del transductor se asocia a dolor significativo durante el procedimiento. El uso tópico de trinitrato de glicerina (NTG) podría proveer alivio adicional. Se evaluó la eficacia y tolerancia de la pasta de NTG tópica y de la combinación BNPP con lidocaína y NTG tópica, comparada con el BNPP de lidocaína. Materiales y Métodos: Entre Marzo de 2005 y Julio de 2006, 144 pacientes consecutivos referidos para una biopsia de próstata de próstata por primera vez fueron randomizados en tres grupos. Grupo 1: BNPP con lidocaína; Grupo 2: Pasta NTG al 0.2 por ciento tópica; Grupo 3: Combinación de BNPP con lidocaína y NTG. Los tratamientos tópicos fueron administrados 30 minutos previo a la biopsia. En todos los pacientes se tomaron 12 muestras. Cada participante completó una escala de dolor visual análoga de 10 puntos después de la introducción del transductor del ecógrafo y al finalizar el procedimiento. Resultados: El dolor de la biopsia fue significativamente menor en los pacientes que recibieron lidocaína sola o en combinación comparada con NTG sola (3.5 v/s 4,8, p<0,05). A su vez la combinación fue superior a lidocaína sola (p = 0.165). No hubo diferencias significativas en relación al dolor debido a la introducción del transductor. En el grupo NTG sola, ocho pacientes (5,6 por ciento) experimentaron cefalea y dos pacientes hipotensión sintomática. Conclusión: La pasta de NTG al 0.2 por ciento tópica es un método efectivo y bien tolerado para disminuir el dolor asociado a la biopsia de próstata ecoguiada. Es seguro y fácil de usar y debiera ser ofrecido a los pacientes que van a ser sometidos a este procedimiento.


Lidocaine periprostatic nervous blockage (LPNB) provides and adequate analgesia for transrectal ultrasound prostate biopsy (TUPB). The placement of the rectal transductor is associated with important pain during the procedure. The topic use of Glicerin trinitrate (GN) could offer improved analgesia during TUPB. We aimed to evaluate analgesic efficacy of GN vs GN + LPNB in TUPB. Methods. Between March 2005 and July 2006, 144 consecutive patients received primary TUPB at our institution. Patients were randomly assigned to three different groups. Group 1: LPNB, Group 2: Topic GN, Group 3: GN + LPNB. Topic treatment were administered 30 minutes before the procedure. All patients received bi sextant biopsy and completed a 10 points analgesic visual scale after transductor placement and at the end of the procedure. Results. Pain sensation was significantly lower in patients in groups 1 and 3 vs group 2 (3.5 vs 4.8, p<0,05). Analgesia was also superior in group 3 vs group 1 (p=0.165). There were no significant differences in pain regarding dutransductor placement. In group 2, eight patients (5,6 percent) experienced cephalea and two other symptomatic hypotension. Conclusion. TG is an effective and well tolerated method for analgesia during TUPB. It is a safe and practical method that could be offered to patients undergoing TUPB.

ABSTRACT

Introducción: La cirugía laparoscópica ha experimentado un auge progresivo durante los últimos años. En la medida que aumenta el número de procedimientos, también aumentan las complicaciones. Objetivo: Presentar la incidencia de complicaciones y la tasa de conversiones de la nefrectomía laparascópica durante su realización por diversas indicaciones, analizando los métodos que ayudarían a prevenirlas.Material y Métodos: Entre junio de 2002 y julio de 2006, se realizaron 95 nefrectomías laparoscópicas, 16simples, 33 radicales y 46 nefrectomías para donante vivo. Se revisaron las fichas clínicas de los pacientessometidos a estas intervenciones para evaluar las complicaciones y analizar los factores relacionados a conversión a cirugía abierta. Resultados: Complicaciones mayores ocurrieron en 6 pacientes (6,32 por ciento). De estas complicaciones 4 fueron de manejo quirúrgico y 1 de manejo médico. La complicación mayor predominante fue sangramiento que requirió conversión a cirugía abierta. La tasa global de conversión fue 3.16 por ciento (3 pacientes). Diez pacientes experimentaron problemas post quirúrgicos menores como retención de orina, infección urinaria e infección de herida operatoria. La mortalidad de la serie fue 0 por ciento. Conclusión: La cirugía renal laparoscópica es cada vez más común en la práctica urológica, pero a pesar de ser una técnica mínimamente invasiva, puede llevar a complicaciones serias. Estas complicaciones pueden prevenirse en el tiempo, con la repetición y experiencia. El conocimiento de estas es esencial paralos urólogos en entrenamiento en cirugía laparoscópica, ya que podría ayudar a disminuir la curva de aprendizaje.


Purpose: We present the incidence of complications and conversions during laparoscopic nephrectomy performed for various indications and discuss methods to prevent future complications. Material and methods. From June 2002 to July 2006 95 laparoscopic nephrectomy cases were performed at our institution,consisting of 27 simple nephrectomies, 33 radical nepherectomies, 33 radical nephrectomies and 46 donor nephrectomies. We reviewed the surgical data of patients who underwent laparoscopic nephrectomy to examine complications and analyze factors related to conversión to an open surgical procedure. Results: Major complications occurred in 6 patients (6.32 percent). Major complications were surgical in 4 patients and medical in 1. The predominant major surgical complication was bleeding requiring conversión to open surgery. Overall conversion rate was 3.16 percent (3 patients). The remaining 10 patients experienced minorsurgical or postoperative medical problems, such as urinary retention or wound infection. No mortality was observed. Conclusions: Laparoscopic renal surgery is becoming a routine procedure in the armamentarium of many urologists. Complications unique to laparoscopy still occurred but they willdecrease with time and experience. We have learned many different precautions and procedures that should help decrease the risk of future complications associated with laparoscopic renal surgery.

ABSTRACT

OBJECTIVES: To report the first case of bladder diverticulectomy in a female patient. METHODS: 74-year-old female patient with a two-year history of recurrent lower urinary tract infection and the diagnosis of big bladder diverticulum. A laparoscopic bladder diverticulectomy was performed. RESULTS: Operative time was 90 minutes. The patient had a satisfactory outcome with the drainage being retrieved on postoperative day three and discharged home the same day with bladder catheter. The catheter was retrieved on postoperative day 7. Cystography showed a normal bladder without diverticulum. CONCLUSIONS: We considered that laparoscopic surgery of the bladder diverticulum is an alternative, completely comparable to classic surgery, and it should be considered an option in the management of bladder diverticula requiring surgery.

ABSTRACT

OBJETIVO: Reportar el primer caso de la diverticulectomía vesical laparoscópica en un paciente femenino. MÉTODOS: Paciente de sexo femenino, de 74 años de edad, con antecedentes de infección recurrente del tracto urinario bajo de aproximadamente 2 años de evolución y diagnóstico de gran divertículo vesical. Se efectuó una diverticulectomía vesical laparoscópica. RESULTADOS: El tiempo operatorio fue de 90 minutos. La paciente evolucionó en forma satisfactoria, retirándose el drenaje al tercer día postoperatorio y siendo dada de alta ese mismo día con sonda uretrovesical. Se retira la sonda al 7° día postoperatorio. El control cistográfico muestra ausencia del divertículo y vejiga normal. CONCLUSIONES: Consideramos que la cirugía laparoscópica del divertículo vesical es una alternativa absolutamente comparable a los procedimientos clásicos, y que debe ser considerada como una opción en el manejo de los divertículos vesicales que requieren resolución quirúrgica (AU)
