Análisis comparativo de costes directos e indirectos de dos técnicas mínimamente invasivas, para el tratamiento de la litiasis renoureteral menor de 2 cm / Comparative analysis of direct and indirect costs of two minimally invasive techniques for the treatment of renal/ureteral calculi smaller than 2 cm

OBJETIVO: Analizar de forma comparativa los costes indirectos y directos de dos técnicas mínimamente invasivas (litotricia extracorpórea (LEOC) vs. ureterorrenoscopia-láser holmium (URS/RIRS)) para el tratamiento de la litiasis reno-ureteral menor de 2 cm. MATERIAL Y MÉTODOS: Estudio prospectivo y comparativo, no aleatorizado de 84 pacientes tratados por litiasis reno-ureteral menor de 2 cm entre enero y diciembre de 2016. De estos, 38 (45,67%) se trataron con LEOC (18 litiasis renales y 20 litiasis ureterales) y 46 (54,32%) con URS/RIRS (22 litiasis renal y 24 litiasis ureteral). Un total de 19 (41,3%) pacientes estaban activos laboralmente en el grupo de URS/RIRS y 15 (39,5%) pacientes en el grupo de LEOC. Las variables analizadas fueron sexo, edad, número y tamaño de las litiasis, días de baja laboral debido al tratamiento, estimación del coste indirecto por la pérdida de productividad laboral y el coste directo del tratamiento aplicado incluyendo el seguimiento (número total de procedimientos, procedimientos auxiliares, visitas y pruebas diagnósticas). Para la estimación del coste indirecto se empleó la Encuesta de Estructura Salarial 2015 (INE). Además, también se utilizó el cuestionario «Work Productivity and Activity Impairment» (WPAI) para determinar el grado de percepción de pérdida de productividad. RESULTADOS: El número medio de sesiones hasta la resolución de la litiasis fue de 2,57 para el grupo de LEOC y de 1,04 para la URS. El promedio de días de baja laboral en el grupo de la URS fue de 7,16 días, mientras que en el caso de la LEOC fue de 3,18 (p = 0,034). Los costes indirectos totales derivados de la pérdida de productividad fueron de 621,55 € y de 276,05 € para la URS y LEOC, respectivamente. Los costes directos en el grupo de la LEOC fueron de 1.382,9 € y 2.317,71 € en el grupo de la URS. El grado de afectación en el trabajo percibido por los pacientes sometidos a URS fue del 18,88% y del 21,33% en el grupo de LEOC. El grado de afectación para realizar actividades cotidianas fue del 24,44% en URS y del 15% en LEOC. CONCLUSIONES: La LEOC es una técnica que precisa de un mayor número medio de sesiones para la resolución de la litiasis reno-ureteral menor de 2 cm, pero con una menor repercusión en los costes totales y en la percepción del grado de afectación

OBJECTIVE: To perform a comparative analysis of indirect and direct costs of two minimally invasive techniques (extracorporeal shock wave lithotripsy (ESWL) vs. ureteroscopy with holmium laser (URS/RIRS)) for the treatment of renal/ureteral calculi smaller than 2 cm. MATERIAL AND METHODS: Prospective, comparative, non-randomized study of 84 patients treated for kidney stones smaller than 2 cm between January and December 2016. Of these, 38 (45.67%) were treated with ESWL (18 renal lithiasis and 20 ureteral lithiasis) and 46 (54.32%) with URS/RIRS (22 renal lithiasis and 24 ureteral lithiasis). A total of 19 (41.3%) patients in the URS/RIRS group and 15 (39.5%) patients in the ESWL group were actively working before treatment. The variables analyzed were sex, age, number and size of lithiasis, time (days) off from work due to treatment, estimate of indirect cost due to labor productivity loss and direct treatment costs including follow-up (total number of procedures, ancillary care, visits and diagnostic tests). The 2015 Wage Structure Survey (INE) was used to estimate the indirect cost. In addition, the «Work Productivity and Activity Impairment» (WPAI) questionnaire was also used to determine the level of perceived productivity loss. RESULTS: The mean number of sessions until lithiasis resolution was achieved was 2.57 for the ESWL group and 1.04 for the URS. The mean number of days off from work in the URS group was 7.16 days and 3.18 (p = 0.034) in the ESWL group. The total indirect costs resulting from productivity loss were EUR 621.55 and EUR 276.05 for the URS and ESWL, respectively. Direct costs in the ESWL group were EUR 1,382.9 and EUR 2,317.71 in the URS group. The level of work impairment perceived by patients undergoing URS was 18.88% and 21.33% in the ESWL group. The degree of impairment for performing activities of daily living was 24.44% in the URS and 15% in ESWL. CONCLUSIONS: The ESWL technique requires a higher number of sessions for the resolution of kidney stones under 2 cm, but it has a lower impact on total costs and on the perceived degree of affectation

Factores predictores de complicaciones infecciosas en el postoperatorio de la nefrolitotomía percutánea / Predictive factors of infectious complications in the postoperative period of percutaneous nephrolithotomy

Objetivo: Las complicaciones infecciosas (CI) tras la nefrolitotomía percutánea (NLPC) pueden llegar a ser de gravedad. Nuestro objetivo fue analizar factores predictores preoperatorios de CI tras la NLPC. Materiales y métodos: Se incluyó en un estudio prospectivo a un total de 203 pacientes que se trataron con NLPC entre enero de 2013 y febrero de 2016. Se definió CI postoperatoria como infección urinaria/pielonefritis, síndrome de respuesta inflamatoria sistémica o sepsis. Las variables analizadas fueron: edad, sexo, número, lado y tamaño (cm) de la litiasis; unidades Hounsfield, diabetes (insulinodependiente o no), cultivo de orina preoperatorio, bacteria aislada, multitrayecto, índice de masa corporal y tiempo quirúrgico (min). Se llevó a cabo un análisis multivariante (regresión logística). Resultados: Se produjeron CI en 30 pacientes (14,8%): en 9 de ellos (4,4%) se presentó infección urinaria, en 14 (6,9%) síndrome de respuesta inflamatoria sistémica y en 7 (3,5%) sepsis. Además, 13 (43,3%) tenían un cultivo de orina preoperatorio negativo, 15 (50%) positivo y en 2 (6,7%) no estaba disponible. En la regresión logística, el tamaño de la litiasis, la diabetes insulinodependiente y el sexo femenino resultaron factores predictores independientes de CI (OR: 1,03; 14,6 y 7,8, respectivamente; p = 0,0001). Conclusiones: Pacientes con litiasis de mayor tamaño, diabéticos insulinodependientes y mujeres deberían ser aconsejados de forma preoperatoria sobre el riesgo de CI tras la NLPC, y ser estrechamente seguidos tras la cirugía. Además, un cultivo de orina preoperatorio negativo no ofrece fiabilidad suficiente para excluir el riesgo de CI

Objective: Infectious complications (IC) following percutaneous nephrolithotomy surgery (PCNL) can be life-threatening. Our objective was to analyze preoperative predictors of IC in PCNL. Materials and methods: A total of 203 patients who underwent PCNL were included in a prospective study between January 2013 and February 2016. A postoperative IC was defined as urinary infection/pyelonephritis, systemic inflammatory response syndrome or sepsis. The variables analyzed were age, gender, number, size (cm) and side of stone; Hounsfield units, diabetes (insulin dependent or not), preoperative culture, isolated bacteria, multitract, body mass index and surgical time (min). A multivariate forward stepwise (logistic regression) was performed. Results: IC occurred in 30 patients (14.8%): 9 (4.4%) had urinary infection, 14 (6.9%) systemic inflammatory response syndrome and 7 (3.5%) sepsis. In addition, 13 (43.3%) had negative preoperative urine culture, 15 (50%) positive and in 2 (6.7%) was not available. On the logistic regression analysis, stone size (cm), insulin dependent diabetes and female sex were independently associated with increased risk of IC (odds ratio [OR] 1.03, 14.6 and 7.8, respectively; p = 0.0001). Conclusions: Patients with large stone burdens, insulin-dependentdiabetes condition and female gender, should be counselled properly regarding postoperative infection risks and closely followed up to diagnose IC (specially sepsis) soon enough. Negative preoperative urine culture seems not reliable enough to exclude an infectious complication according to our results

Litotricia por ondas de choque con música: un tratamiento menos doloroso y más satisfactorio / Shockwave lithotripsy with music: Less painful and more satisfactory treatment

Introducción: El objetivo del estudio fue determinar si escuchar música durante una sesión de litotricia extracorpórea por ondas de choque (LEOC) mejora el dolor de los pacientes. Material y método: Se realizó una aleatorización simple y oculta de pacientes con litiasis renales o ureterales que acudieron por vez primera a una sesión de LEOC de 7.000 ondas, entre septiembre y diciembre de 2014. Un grupo recibió música mientras que el otro no. Se registraron la edad, sexo, localización de la litiasis (renal/ureteral) y 2 cuestionarios pre-LEOC (cuestionario A) y post-LEOC (cuestionario B). Cada cuestionario contiene una pregunta sobre ansiedad y otra sobre dolor en escala Likert (0 al 10). El B, además, contiene otra sobre satisfacción y otra sobre comodidad (Likert 0 al 10). Otras variables fueron la frecuencia cardiaca, respiratoria, tensión arterial sistólica y diastólica en la onda 2.000, 5.000 y 7.000, causa de interrupción del procedimiento, petidina total (mg), analgesia secundaria, energía (J) y frecuencia (Hz). Se realizó un análisis bivariante con t de Student, X2/Fisher y un modelo de regresión lineal múltiple. Resultados: La muestra incluyó a 95 pacientes, con una media de edad de 52 años (±13), 35 mujeres (36,84%), 60 hombres (63,2%); 25 para litiasis ureterales (26,3%) y 70 (26,3%) para renales (73,7%). Un total de 42 pacientes (44,2%) pacientes recibieron música. No hubo diferencias entre las variables demográficas ni en las puntuaciones del cuestionario A. La satisfacción y el dolor fueron mejores en el cuestionario B con música. Conclusión: La música es capaz de disminuir el dolor y mejorar la satisfacción del paciente en los tratamientos con LEOC. Más estudios son necesarios para comprobar este efecto

Introduction: The objective of this study was to determine whether listening to music during a session of extracorporeal shockwave lithotripsy (ESWL) improves patients' pain. Material and method: A simple, blind randomisation was undertaken of patients with kidney and ureter stones attending an ESWL session of 7,000 waves for the first time, between September and December 2014. One group was given music and the other was not. The age, gender, location of stones (kidney/ureter) were recorded and 2 questionnaires: pre ESWL (questionnaire A) and postESWL (questionnaire B). Each questionnaire contained a question about anxiety and another question on pain on the Likert scale (0-10). Questionnaire B also had a question on satisfaction and comfort (Likert 0-10). Other variables included heart rate, respiratory rate, systolic and diastolic blood pressure on wave 2,000, 5,000 and 7,000, reason for halting the procedure, total pethidine (mg), secondary analgesia, energy (J) and frequency (Hz). Bivariate analysis using the Student's t-test, X2/Fisher test and a multiple linear regression model. Results: The sample comprised 95 patients, with a mean age of 52 (±13) years, 35 (36.84%) females, 60 (63.2%) males. A total of 25 (26.3%) ureter stones and 70 (73.7%) kidney stones. A number of 42 (44.2%) patients were given music. There were no differences between the demographic variables or questionnaire A scores. Satisfaction and pain were better on questionnaire B with music. Conclusion: Music can reduce pain and improve patient satisfaction in ESWL treatment. More studies are required to confirm this effect

¿Es la litotricia extracorpórea por ondas de choque en la actualidad un tratamiento vigente para el tratamiento de la litiasis urinaria? Revisión sistemática / Is extracorporeal shock wave lithotripsy a current treatment for urolithiasis? A systematic review

Introducción: Los avances tecnológicos han motivado un cambio en el manejo de la urolitiasis. Las técnicas endourológicas están cobrando mayor importancia, ya que son tratamientos altamente eficaces. El objetivo de este trabajo es responder a la cuestión de si la LEOCH sigue siendo una alternativa competitiva frente a otras modalidades terapéuticas. Adquisición de la evidencia: Se realizó una búsqueda bibliográfica de artículos publicados en los últimos 5 años. Fueron identificados 12 estudios aleatorizados y comparativos. Se evaluó la metodología y el resultado de las variables estudiadas. Se ha realizado una síntesis narrativa de los estudios incluidos. Para resumir las variables se ha utilizado la media y la desviación estándar en variables continuas, y para variables cualitativas el número absoluto y el porcentaje. Análisis de la evidencia: De los estudios revisados, 7 trabajos evaluaban los distintos tratamientos para litiasis renales y 5 para litiasis ureterales. A nivel renal, con LEOCH se alcanza una TLL a los 3 meses entre 91,5-33,33%, mientras que con otras técnicas endourológicas entre 100-90,4%, sin encontrar diferencias estadísticamente significativas en todos los estudios. A nivel ureteral con LEOCH se alcanza una TLL a los 3 meses entre 82,2-73,5%, mientras que con otras técnicas endourológicas entre 94,1-79%, sin encontrar diferencias estadísticamente significativas todos los estudios. Conclusión: Existe una falta de homogeneidad entre los estudios publicados. La LEOCH es un tratamiento mínimamente invasivo, que con una adecuada técnica y selección del paciente alcanza una elevada efectividad, manteniendo un papel importante en la actualidad

Introduction: Technological advances have prompted a change in the management of urolithiasis. Endourological techniques are gaining importance because they are highly effective treatments. The aim of this study was to answer the question of whether extracorporeal shock wave lithotripsy (ESWL) is still a competitive alternative compared with other therapeutic modalities. Acquisition of evidence: We conducted a literature search of articles published in the past 5 years. We identified 12 randomized and comparative studies and assessed the methodology and results of the study variables. We performed a narrative synthesis of the included studies. To summarise the variables, we used the mean and standard deviation for continuous variables and absolute numbers and percentages for the qualitative variables. Analysis of the evidence: Of the studies reviewed, 7 evaluated the various treatments for nephrolithiasis and 5 evaluated the treatments for ureteral lithiasis. At the renal level, a stone-free rate of 33.33-91.5% at 3 months was reached with ESWL, while a rate of 90.4-100% was achieved with the other endourological techniques, without finding statistically significant differences in the studies. At the ureteral level, a stone-free rate of 73.5-82.2% at 3 months was reached with ESWL, while a rate of 79-94.1% was achieved with the other endourological techniques, without finding statistically significant differences in the studies. Conclusion: There is a lack of homogeneity among the published studies. ESWL is a minimally invasive treatment that with an appropriate technique and patient selection achieves high effectiveness, thus maintaining an important role at this time

Análisis de riesgos competitivos de mortalidad en cáncer de próstata tratado mediante prostatectomía radical / Competing risk analysis of mortality in prostate cancer treated with radical prostatectomy

Objetivo: Estimar el riesgo de muerte cáncer específica (MCE) frente al riesgo competitivo de mortalidad por otras causas (MOC) en pacientes con cáncer de próstata localizado (CaP-Lo) tratados mediante prostatectomía radical (PR). Material y método: Estudio observacional de una cohorte de 982 pacientes con CaP-Lo tratados mediante PR seleccionados de la base de datos del registro de CaP de nuestro servicio. Se ha realizado un análisis de riesgos competitivos calculando la probabilidad de MCE en presencia del riesgo competitivo por MOC. Se han construido curvas de incidencia acumulada y se han llevado a cabo estimaciones puntuales a 5, 10 y 15 años. El análisis se ha estratificado por edad (≤ 65 vs. > 65 años) y por grupos de riesgo: bajo (Gleason ≤ 6 y pT2abc); intermedio (Gleason = 7 y pT2abc) y elevado (Gleason 8-10 o pT3ab). Resultados: Con una mediana de seguimiento de 60 meses, la probabilidad global de fallecer por CaP fue del 3,5% y la de fallecer por otras causas del 9%. Se evidenció un efecto competitivo por MOC. El riesgo de MOC fue de casi 3 veces superior al de MCE. Este efecto se mantuvo para todos los grupos de riesgo, si bien su magnitud disminuyó progresivamente conforme aumentó el nivel del grupo de riesgo. A 10 años, la MCE fue únicamente de 0, 1 y 2% para los grupos de riesgo bajo, intermedio y elevado respectivamente, mientras que la probabilidad MOC fue de 4, 4 y 10%. El riesgo de fallecer se evidenció a partir de 10 años de seguimiento y fue más frecuente por otras causas no atribuibles al CaP y en pacientes de edad > 65 años. Conclusiones: El beneficio de la PR puede estar sobreestimado, ya que el riesgo de MOC es superior al de MCE independientemente del grupo de edad y grupo de riesgo, sobre todo a partir de los 10 años de seguimiento. Lo único que varía es la magnitud de la razón MCE/MOC. Esta información puede ayudar a decidir el tratamiento activo en pacientes con CaP-Lo y corta expectativa de vida

Objective: To determine the risk of cancer-specific mortality (CSM) versus the competing risk of mortality by other causes (MOC) in patients with localised prostate cancer (LPC) treated with radical prostatectomy (RP). Material and method: An observational cohort study of 982 patients with LPC treated with RP selected from our department’s PC registry database. A competing risk analysis was performed, calculating the probability of CSM in the presence of the competing risk of MOC. Cumulative incidence curves were constructed, and point estimates were performed at 5, 10 and 15 years. The analysis was stratified by age (≤ 65 vs. > 65 years) and risk group: low (Gleason score ≤ 6 and pT2abc); intermediate (Gleason score of 7 and pT2abc) and high (Gleason score of 8-10 or pT3ab). Results: With a median follow-up of 60 months, the overall probability of dying from PC was 3.5%, and the probability of dying from other causes was 9%. A competing effect for MOC was observed. The risk of MOC was almost 3 times greater than that of CSM. This effect remained for all risk groups, although its magnitude decreased progressively according to the risk group level. At 10 years, CSM was only 0%, 1% and 2% for the low, intermediate and high-risk groups, respectively, while the likelihood of MOC was 4%, 4% and 10%, respectively. The mortality risk was shown after 10 years of follow-up and was higher for other causes not attributable to PC and for patients older than 65 years. Conclusions: The benefit of RP might be overestimated, given that the risk of MOC is greater than that of CSM, regardless of the age group and risk group, especially after 10 years of followup. The only parameter that varied was the magnitude of the CSM/MOC ratio. This information could help in choosing the active treatment for patients with LPC and short life expectancies

[Impact in the quality of life of the patients with double J catheter.] / Impacto en la calidad de vida de los pacientes con catéter doble J.

OBJECTIVE: Double J ureteral stents are frequently used to allow free diuresis from the kidney to the bladder, but their presence has a major impact on patient's quality of life (QoL). Our aim is to describe such impact, and to describe possible solutions that can alleviate the symptoms associated with their use. METHODS: Systematic search in bibliographic sources including Cochrane library, UpToDate, Pubmed, Tripdatabase, selecting publications between 2000- 2015, and also the EAU European guidelines (2016). Studies that assessed QoL with double J stents and possible solutions were selected. RESULTS: We included 6 qualitative studies on QoL, 6 clinical trials of double J catheters new designs, and 3 systematic reviews. Most studies used the USSQ (QoL) questionnaire and main problems are described, being storage symptoms and pain the most frequent and important. Possible solutions include modifications in design and composition of the catheter and specially, the use of alpha-blockers and anticholinergics to improve QoL. CONCLUSION: Double J stents have an important symptomatic impact that impairs QoL. They should be used under appropriate indication; their duration should be limited and we must employ all the technological and pharmacological approaches to mitigate their effects.

Análisis del perfil de seguridad del tratamiento con un número ampliado de ondas de choque por sesión en litotricia extracorpórea / Analysis of the safety profile of treatment with a large number of shock waves per session in extracorporeal lithotripsy

Objetivo: Evaluar la seguridad del incremento del número de ondas por sesión en el tratamiento de la litiasis urinaria mediante litotricia extracorpórea. Material y métodos: Estudio prospectivo, comparativo, no aleatorizado, de grupos paralelos de pacientes con litiasis reno-ureteral e indicación de litotricia extracorpórea incluidos consecutivamente entre 2009 y 2010. Se comparó un grupo i (160 pacientes) tratado programadamente con un número medio de ondas/sesión estándar (2858,3 ± 302,8) y un litotriptor Dornier Lithotripter U/15/50, frente a un grupo ii (172 pacientes) tratado con un número medio de ondas/sesión ampliado (6728,9 ±889,6) y un litotriptor Siemens Modularis. Las variables analizadas fueron edad, sexo, localización, tamaño de la litiasis, número de ondas/sesión y totales hasta la resolución, tasa libre de litiasis (TLL) y tasa de complicaciones (clasificación Clavien-Dindo). Para el análisis estadístico fueron empleados la «t» de Student y la Chi cuadrado. Resultados: La tasa de complicaciones totales fue 11,9% para el grupo i y 10,46% para el grupo ii (p = 0,39). Todas ellas fueron complicaciones menores grado i (Clavien-Dindo). La más frecuente en el grupo i fue el dolor cólico y en el grupo ii la hematuria, con tasa de intolerancia al tratamiento similar (p > 0,05). El número de ondas totales necesarias fue inferior en el grupo ii respecto al grupo i (p = 0,001), con TLL del 96,5% y 71,5% respectivamente (p = 0,001). Conclusión: El tratamiento con un número ampliado de ondas por sesión en litotricia extracorpórea no implica mayor tasa de complicaciones ni mayor severidad de las mismas. Sin embargo, podría aumentar la efectividad global del tratamiento

Objective: To assess the safety of increasing the number of waves per session in the treatment of urolithiasis using extracorporeal lithotripsy. Material and methods: Prospective, comparative, nonrandomized parallel study of patients with renoureteral lithiasis and an indication for extracorporeal lithotripsy who were consecutively enrolled between 2009 and 2010. We compared group I (160 patients) treated on schedule with a standard number of waves/session (mean 2858,3 ± 302,8) using a Dornier lithotripter U/15/50 against group II (172 patients) treated with an expanded number of waves/session (mean, 6728,9 ± 889,6) using a Siemens Modularis lithotripter. The study variables were age, sex, location, stone size, number of waves/session and total number of waves to resolution, stone-free rate (SFR) and rate of complications (Clavien-Dindo classification). Student's t-test and the chi-squared test were employed for the statistical analysis. Results: The total rate of complications was 11.9% and 10.46% for groups I and II, respectively (P = .39). All complications were minor (Clavien-Dindo grade I). The most common complications were colic pain and hematuria in groups I and II, respectively, with a similar treatment intolerance rate (P > .05). The total number of waves necessary was lower in group II than in group I (P = .001), with SFRs of 96.5% and 71.5%, respectively (P = .001). Conclusion: Treatment with an expanded number of waves per session in extracorporeal lithotripsy does not increase the rate of complications or their severity. However, it could increase the overall effectiveness of the treatment

[Watchful waiting in incidental adenocarcinoma of the prostate]. / Actitud expectante en el adenocarcinoma incidental de próstata.

OBJECTIVE: To describe the outcome of patients diagnosed of incidental prostate adenocarcinoma managed by watchful waiting. MATERIAL AND METHODS: We included patients with PSA< 4 ng/mL or higher with previous negative biopsy, who underwent surgery for BPH being diagnosed of incidental prostate adenocarcinoma. We performed a descriptive and retrospective study in patients with this diagnosis between 1992 and 2007. Salvage curative treatment was offered to those patients who progressed. Statistical analysis was performed using SPSS program. Progression variables were: age, preoperative and postoperative PSA, stage, Gleason score, prostate volume, initial treatment, PSA evolution and salvage treatment if necessary. RESULTS: 47 patients were diagnosed of incidental prostatic adenocarcinoma, finding an incidence of 4.25%. The medium follow up was 37 months. Of the patients who opted for watchful waiting, 72.5% remain on it. 11 patients progressed. Postoperative PSA and Gleason score showed up as prognostic variables of progression in T1a stage and postsurgery PSA did so in T1b patients. CONCLUSION: Watchful waiting is a useful option in patients with incidental prostate adenocarcinoma and favourable prognostic criteria. Postoperative PSA and Gleason score can predict progression in T1a stage and postoperative PSA in T1b stage.

Actitud expectante en el adenocarcinoma incidental de próstata / Watchful waiting in incidental adenocarcinoma of the prostate

Objetivo: Describir la evolución de los pacientes con adenocarcinoma de próstata incidental manejados mediante actitud expectante. Material y métodos: Se incluyen pacientes intervenidos de hiperplasia benigna prostática, con PSA <4ng/ml o > de 4 con biopsia previa negativa para tumor, diagnosticándose de adenocarcinoma prostático incidental al analizar la muestra. Se realiza un estudio retrospectivo y descriptivo, en pacientes con este diagnóstico entre 1992 y 2007. Se ofreció tratamiento curativo de rescate con prostatectomía radical/radioterapia a los pacientes que progresaron. El análisis estadístico se realiza mediante el programa SPSS. Las variables de progresión analizadas son: edad, PSA prequirúrgico y posquirúrgico, estadio, Gleason, volumen prostático, tratamiento inicial, evolución de PSA y tratamiento diferido. Resultados: 47 pacientes fueron diagnosticados de adenocarcinoma prostático incidental, encontrando una incidencia de 4,25%, con un seguimiento medio de 37 meses. De los pacientes que optaron por actitud expectante, el 72,5% permanecen en vigilancia. Once pacientes progresaron. El grado de Gleason y el PSA posquirúrgico resultaron variables de progresión en el estadio T1a y el PSA posquirúrgico en el estadio T1b. Conclusiones: La actitud expectante es una opción adecuada en pacientes con adenocarcinoma de próstata incidental con criterios de buen pronóstico. El PSA posquirúrgico y el grado de Gleason son variables que pueden predecir la progresión de pacientes en estadio T1a y el PSA posquirúrgico lo es en el estadio T1b (AU)

Características clínicas e histopatológicas del cáncer de próstata diagnosticado a partir de la tercera biopsia / Clinicla features and histopathology of prostate cancer diagnosed from the third biopsy

Objetivo: Estudiar las características histopatológicas y clínicas de los tumores diagnosticados a partir de terceras biopsias para valorar la relevancia clínica de éstos y descartar el sobre diagnóstico en el cáncer de próstata. Material y método: Revisamos las historias clínicas de 61 pacientes con al menos tres o más biopsias de próstata transrectales, sextantes o de saturación según el esquema preestablecido, desde el año 2000 al 2006. Las variables analizadas son: edad del paciente, PSA, cociente PSA libre/PSA total, PSA densidad, tacto rectal, volumen prostático, hallazgos ecográficos y lesión premaligna fuertemente asociadas a la presencia de tumor en biopsias previas. Y estudiamos la anatomía patológica de los tumores diagnosticados a partir de la tercera biopsia, abordaje terapéutico y su evolución con un seguimiento mínimo de 3 meses. Resultados: De 61 pacientes con más de tres biopsias, a 15 pacientes se les diagnostica cáncer (24,6%) en la tercera biopsia. A 14 se les realiza nueva biopsia (cuarta), encontrando tumor en 5 de ellos (35,7%). Se realiza quinta biopsia en2 pacientes siendo positiva en uno de ellos (50%). Según los resultados de la biopsia, 6 pacientes presentaban criterios de cáncer clínicamente no significativo (28,6%). En todos los pacientes se procedió a tratamiento curativo: 5 braquiterapia,6 radioterapia externa y a 10 se les realizó una prostatectomía radical, que evidenció tumores clínicamente significativos: 2 tumores pT2b y 7 tumores pT2c sin invasión de los márgenes quirúrgicos y con un excelente control de la enfermedad tras un seguimiento mínimo de 13 meses y un pT4 por invasión del cuello vesical. Conclusiones: En nuestro medio, la tercera, cuarta y quinta biopsia alcanza una positividad del 34,42% y se corresponde con tumores que se benefician de un tratamiento con intención curativa(AU)

Objective: To study of histological and clinical features of prostate cancer diagnosed after three or more prostate biopsies in order to assess its clinical relevance and to discard the over diagnosis of prostate cancer. Material and methods: We reviewed the clinical records of 61 patients who underwent three or more prostate biopsies between January 2000 and December 2006. The analyzed variables were: age, PSA level, free/total PSA ratio, PSA density, digital rectal examination, prostate volume, sonographic findings and previous malignant lesion strongly associated to the presence of tumor on previous biopsy. We studied the pathology of the tumors diagnosed from the third biopsy, therapeutical approach and its evolution with a minimum follow-up of 3 months. Results: Fifteen out of 61 patients with more than three biopsies had prostate cancer (24,59%) in the third biopsy, 5out of 14 patients with 4 biopsies (35,71%) and 1 of the 2 cases (50%) who underwent a fifth biopsy. According to the results of biopsy, 6 patients met the criteria of clinically insignificant cancer (28,57%). Curative treatment was performed in all patients: brachytherapy in 5, external beam radiotherapy in 6 and radical prostatectomy in 10. Clinically significant tumors were found in all cases: 2 pT2b tumors and 7 pT2c tumors with negative surgical margins and with an excellent control of the cancer after a minimum follow up of 13 months, and one pT4 tumor with bladder neck infiltration. Conclusion: In our practice, overall detection rate of the third, fourth and fifth biopsy is 34,42% corresponding with tumors that could benefit from curative treatment (AU)

Desarrollo de un Modelo Matemático preliminar para la detección de cáncer de próstata en los pacientes con biopsias prostáticas de repetición / A preliminar mathematical model for patients with a previous negative prostate biopsy

Objetivo: Analizamos las variables clínicas e histopatológicas de los pacientes hombres a biopsiar por sospecha de cáncer de próstata y cuáles de ellos tienen carácter pronóstico para los pacientes con biopsia previa sin hallazgos de neoplasia. Pretendemos desarrollar un nomograma que nos ayude en la decisión de indicar la repetición de la prueba. Material y método: Incluimos 179 pacientes con, al menos una biopsia previa sin hallazgos neoplásicos. Registramos, antes de cada biopsia, edad del paciente, antígeno próstatico específico (PSA) total, PSA libre/total, densidad del PSA, velocidad del PSA, tacto rectal, volumen ecográfico, aparición de área sospechosa en la escala de grises durante la ecografía transrectal, número de cilindros biopsiados, lesiones histológicas premalignas en alguna de las biopsias previas, así como el tiempo transcurrido entre las biopsias. Mediante un modelo de regresión logística determinamos la asociación de cada variable con la presencia de cáncer (biopsia positiva). Construimos un nomograma con las variables estadísticamente más relevantes y averiguamos la capacidad de discriminación del modelo mediante el índice de concordancia. Resultados: Nuestras biopsias de repetición consiguen una tasa de detección de cáncer del 46%. En el estudio univariante la edad, el tacto rectal, el volumen prostático, la densidad del PSA, las zonas sospechosas en la escala de grises, y las lesiones histológicas premalignas se asocian a biopsia de repetición positiva para cáncer (p <0.05). En el análisis multivariante, la edad, el tacto rectal, el volumen prostático y los antecedentes histológicos de una lesión preneoplásica se asociaron a biopsia positiva. Construimos un nomograma con un índice de concordancia de 0,80.Conclusión: A expensas de una validación prospectiva externa de nuestro modelo, el nomograma desarrollado podría ser de ayuda en la difícil de tarea de indicar una biopsia de repetición (AU)

Introduction and objectives: It is usual to identify patients with a negative prostate biopsy who are still at risk of prostate cancer. We try to analyse if the classical variables used in the prostate cancer screening are useful for those patients with a previous negative prostate biopsy, and if there is a possibility for making a nomogram witch would help us in the decision to repeat the biopsy. Material and methods: We studied 179 patients with at least 1 initial negative biopsy. At each biopsy session we recorded: Patient age, serum prostate specific antigen (PSA), free PSA/total PSA, PSA slope, digital rectal examination, prostate volume, PSA density, cancer suspicion in previous transrectal ultrasounds findings, number of negative cores previously obtained, history of precarcinomatous lesions and time between biopsies. Through Logistic regression analysis we determined the association of each variable a positive biopsy. A nomogram was constructed using all variables and discrimination was calculated as the concordance index. Results: Overall 46% of patients had cancer at the repeated biopsy session. In the univariate analysis: Age, digital rectal examination, prostate volume, PSA density, cancer suspicion in ultrasounds findings, and precarcinomatous lesions were associated with repeat positive biopsy for cancer (all p <0.05). In the multivariate study, age, digital rectal examination, prostate volume and history of precarcinomatous lesions were associated with repeat positive biopsy. Anomogram was constructed that had a concordance index of 0.80 (AU)

Estrategias para la biopsia de próstata. Revisión de la literatura / Prostate biopsy strategies. A review of the literature

Introducción: Desde que en 1987 se describió la ecografía transrectal como técnica para dirigir la biopsia de próstata, diferentes modalidades de la misma han sido utilizadas para la detección del cáncer de próstata. Material y Método: Realizamos una revisión de las diferentes técnicas y esquemas de distribución de los cilindros de la biopsia prostática, así mismo describimos la preparación del paciente y las complicaciones más relevantes. Resultados: La mayoría de los trabajos al respecto comunica una mejora de la sensibilidad de la prueba con las biopsias prostáticas transrectales ecodirigidas ampliadas respecto a la técnica sextante clásica. Dicha ampliación se da a expensas de cilindros generalmente de las zonas más laterales de la zona periférica. Conclusiones: Hasta el momento, dado que se cuenta con una amplia experiencia y la tasa de complicaciones es asumible, la biopsia prostática transrectal ecodirigida, debiera ser ampliada respecto a la sextante clásica a expensas de cilindros de las zonas periféricas laterales prostáticas

Introduction: In 1987 transrectal ultrasound was described like the technique for guiding prostate biopsy. Since that time different options of transrectal ultrasound guided prostate biopsy were described. Material and Methods: We did a reviewed of the different techniques and cores distribution in the prostate biopsy, also we describes the patient preparation and the most important complications. Results: The majority of the reviewed showed an increase in the sensibility rates with the extended transrectal ultrasound guided prostate biopsies. These improvements generally are due to the most lateral zones. Conclusion: Until now, due to a great experience and a low complications rate, the transrectal ultrasound guided prostate biopsy strategy should be extended respect the classical sextant biopsy with cores from the most lateral zones of the prostate

Análisis de la adherencia de los urólogos españoles a las recomendaciones de diagnóstico y tratamiento de las guías de práctica clínica sobre incontinencia urinaria / Analysis of the spanish urologists adherence to the recomendations of the guidelines on diagnostic and treatment of urinary incontinence

Objetivo: Ante la carencia de datos sobre el grado de adherencia a las guías clínicas sobre incontinencia urinaria, el objetivo fue conocer cómo la diagnostican y tratan los urólogos españoles. Material y métodos: Sondeo de opinión quasi nacional sobre 202 urólogos en 20 reuniones representativas. Se realizaron 2 preguntas de diagnóstico y 2 de tratamiento, agrupando las respuestas por concepto. Se uso el método Grupo Focal dinamizado con 'brain storming estructurado'. La adherencia se estimó por la concordancia entre lo recomendado y lo practicado. Los resultados se promediaron según el total de respuestas. Resultados: La adherencia fue: anamnesis 88%, exploración física 78%, analítica 47%, sedimento 72% y cultivo 67%. Para la urodinámica fue del 23% y para el uso de cuestionarios de síntomas y calidad de vida fue minoritaria con 14% y 26%. La adherencia a preguntas correctas sobre el tipo de incontinencia fue muy elevada, necesitándose sólo 2,7 preguntas de media para el diagnóstico correcto. En el tratamiento de la incontinencia mixta, un 85% abordó primero la urgencia y un 11% el esfuerzo. El 27% considera que el principal motivo es la disponibilidad de drogas. Para el tratamiento de la incontinencia de urgencia, la adherencia al uso de antimuscarínicos fue del 98% y la de la modificación de hábitos del 50%. En la incontinencia de esfuerzo, la adherencia en el uso de ejercicios del suelo pélvico fue del 81% y para la cirugía del 53%. Conclusiones: La adherencia de los urólogos españoles a las guías de IU está lejos de lo ideal. Aún con sesgos, los resultados pueden considerarse representativos. Es deseable que, en la creación de guías, se diseñen indicadores que midan el grado de adherencia

Objetive: Data regarding the degree of adherence to urinary incontinence guidelines are not available. The aim of this study was to know how the spanish urologist diagnos and treat urinary incontinence. Material and methods: This is an opinion poll from 202 urologist underwent in 20 representative meetings of the Spain. The poll consisted of 2 questions about diagnostic and 2 about treatment of urinary incontinence. The anwsers were grouped by ideas. The focal group method dinamized by “structured brain storming” was used. We evaluate the adherence to the incontinence guide lines analizing the agreement between the recommendations and the real practice. We average acording all obtained responses. Results: The adherence were: history 88%, physical examination 78%, blood test 47%, urunalysis 72% and urine culture 67%. The adherence for urodynamic investigation was 23%. The use of symptom and quality of life cuestionares was minority (14% y 26%). The adherence to the right questions about the type of incontinece was very high. An average of 2.7 questions to reach correct diagnoses was needed. A 85% of urologist treat urge compenent of mixed incontinence firstly and 11% the stress component. The 27% considered the availability of drug as the main reason for such prioritization. The adherence of treating urge incontinence with antimuscarics was 98% and of life style interventions 50%. For treating stress urinary incontinence, the adherence to pelvic floor muscle training was 81% and to surgery 53%. Conclusions: Spanish urologist adherence to incontinence urinary guidelines is far from the ideal. Although this study may have bias, the outcome can be considered as representative of the situation. It is desirable that, in the process of guidelines creation, specific parameters to assess the degree of adherence be designed
