Three-Year Treatment Outcomes of Water Vapor Thermal Therapy Compared to Doxazosin, Finasteride and Combination Drug Therapy in Men with Benign Prostatic Hyperplasia: Cohort Data from the MTOPS Trial.

PURPOSE: We evaluated the long-term outcomes of treatment of lower urinary tract symptoms due to benign prostatic hyperplasia to compare a 1-time water vapor thermal therapy procedure with daily medical therapy in cohorts from the MTOPS (Medical Therapy of Prostatic Symptoms) study. MATERIALS AND METHODS: Results in the treatment arm of a randomized, controlled trial of thermal therapy using the Rezum® System were compared to MTOPS subjects treated with doxazosin and/or finasteride. Evaluations were restricted to medical therapy subjects, representing 1,140 of the original 3,047 (37.4%), with a prostate volume of 30 to 80 cc and an International Prostate Symptom Score of 13 or greater to include men who met key criteria of the Rezum and MTOPS trials. Outcomes were compared during 3 years for symptom changes and clinical progression rates. RESULTS: Thermal therapy improved symptom scores by approximately 50% throughout 36 months (p <0.0001). Symptom improvement was greater than with either drug alone but similar to that of combination drugs (p ≤0.02 and 0.73, respectively). The peak flow rate improved 4 to 5 ml per second after thermal therapy and doxazosin while thermal therapy was superior to finasteride and combination drugs for 24 and 12 months (p <0.001 and <0.01, respectively). Observed rates of clinical progression during 3 years corroborate these outcomes with approximately 5 times greater progression for any medical therapy vs a single thermal therapy procedure. CONCLUSIONS: A single water vapor thermal therapy procedure provided effective and durable improvements in symptom scores with lower observed clinical progression rates compared to daily long-term use of pharmaceutical agents.

Percepción del dolor en cistoscopia flexible con el uso de lidocaína intrauretral / Perception of pain in flexible cystoscopy using intraurethral lidocaine

OBJETIVO: La cistoscopia flexible es una técnica utilizada en el diagnóstico de la patología del tracto urinario inferior. El objetivo de este estudio es evaluar la eficacia del anestésico local intrauretral en la percepción del dolor en el paciente. MÉTODOS: Estudio observacional prospectivo no aleatorizado que incluye 142 hombres a los que se realiza cistoscopia flexible. Se dividen en dos grupos en función del uso o no de anestésico local intrauretral (Grupo 1: 70 hombres con anestésico intrauretral [lidocaína 2%]; Grupo 2: 72 hombres sin anestésico intrauretral). Se analiza escala visual analógica y cuestionario del dolor. Análisis estadístico con SPSS 17.0 y significación estadística p≤0,05. RESULTADOS: La edad media del grupo 1 fue de 64,7±10,3 años frente a 66,7±10,8 años en el grupo 2, sin diferencias significativas. La puntuación en la escala visual analógica en el grupo 1 fue 2,23±2,20 frente a 1,69±1,74 en el grupo 2 (p = 0,1). La intensidad del dolor total y actual en el cuestionario del dolor fue de 1,81 ± 0,87 y 1,66 ± 1,65, respectivamente, en el grupo 1 y de 1,72 ± 0,72 y 1,21±1,45, respectivamente, en el grupo 2 (no diferencias significativas). Tras dividir a los pacientes en función de una puntuación en la escala visual analógica ≤ 2, se observa que la causa que motivó la cistoscopia es un factor independiente asociado a la percepción del dolor, incrementando el riesgo de percibir más dolor en 1,89. CONCLUSIÓN: El uso de anestésico local como lubricante previo a cistoscopia flexible no parece disminuir el dolor y consideramos que no está indicado de rutina en esta técnica diagnóstica

OBJECTIVE: The aim of this study is to evaluate the efficacy of a local intraurethral anesthetic on the pain perceived by the patient during flexible cystoscopy. METHODS: An observational, prospective, nonrandomized, study was conducted on 142 males subjected to a flexible cystoscopy. The patients were divided into two groups: Group 1: 70 patients with intraurethral anesthetic (lidocaine 2%), and Group 2:72 patients without intraurethral anesthetic. The results were scored on a visual analog scale and a pain questionnaire and analyzed. The statistical analysis was performed using SPSS 17.0 and with a statistical significance of p ≤ 0.05. RESULTS: The mean age of Group 1 was 64.7 ± 10.3 years compared to 66.7 ± 10.8 years in Group 2, with no significant differences. The score on the visual analog scale in Group 1 was 2.23 ± 2.20 versus 1.69 ± 1.74 in Group 2 (p = 0.1). The overall and current pain intensity in the pain questionnaire was 1.81 ± 0.87 and 1.66 ± 1.65, respectively, in Group 1, and 1.72 ± 0.72 and 1.21 ± 1.45, respectively, in Group 2 (no significant differences). After dividing the patients into groups according to a visual analog scale score ≤ 2, it was observed that the cause that led to cystoscopy was an independent factor associated with the perception of pain, increasing the risk of perceiving more pain by 1.89. CONCLUSIÓN: The use of local anesthetic as a lubricant prior to flexible cystoscopy does not appear to reduce pain, and we consider that its routine use is not indicated

Temporary implantable nitinol device (TIND): a novel, minimally invasive treatment for relief of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH): feasibility, safety and functional results at 1 year of follow-up.

OBJECTIVES: To report the first clinical experience with a temporary implantable nitinol device (TIND; Medi-Tate(®) ) for the treatment of lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: In all, 32 patients with LUTS were enrolled in this prospective study, which was approved by our Institutional Ethics Committee. Inclusion criteria were: age >50 years, International Prostate Symptom Score (IPSS) of ≥10, maximum urinary flow rate (Qmax ) of ≤12 mL/s, and prostate volume of <60 mL. The TIND was implanted within the bladder neck and the prostatic urethra under light sedation, using a rigid cystoscope. The device was removed 5 days later in an outpatient setting. Demographics, perioperative results, complications (according to the Clavien system), functional results and quality of life (QoL) were evaluated. Follow-up assessments were made at 3 and 6 weeks, and 3, 6 and 12 months postoperatively. The Student's t-test, analysis of variance (anova), Kruskall-Wallis test, and simple and multiple linear regression models were used in the statistical analyses. RESULTS: The mean patient age was 69.4 years, the mean (standard deviation, sd) prostate volume was 29.5 (7.4) mL and the Qmax was 7.6 (2.2) mL/s. The median (interquartile range, IQR) IPSS was 19 (14-23) and QoL score was 3 (3-4). All the implantations were successful, with no intraoperative complications recorded. The mean operative time (sd) was 5.8 (2.5) min and the median (IQR) postoperative stay was 1 (1-2) day. All but one of the devices (96%) was removed 5 days at after implantation in an outpatient setting. Four complications (12.5%) were recorded, including urinary retention (one, 3.1%), transient incontinence due to device displacement (one, 3.1%), prostatic abscess (one, 3.1%), and urinary tract infection (one, 3.1%). Multiple regression analysis failed to identify any independent prognostic factor for complications. There were statistically significant differences in the IPSS, QoL score and Qmax when comparing pre- and postoperative results at every time point. After 12 months, the median (IQR) IPSS and QoL score were 9 (7-13) and 1 (1-2), respectively, and the mean (sd) Qmax was 12 (4.7) mL/s. The mean variations with respect to baseline conditions at the same time points were -45% for the IPSS and +67% for Qmax . At 12 months after surgery (last follow-up visit), no patients required medical therapy or surgical procedures for BPH. CONCLUSION: TIND implantation is a feasible and safe minimally invasive option for the treatment of BPH-related LUTS. The functional results are encouraging and the treatment significantly improved patient QoL. Further studies are required to assess durability of TIND results and to optimise the indications of such a procedure.

Uretrotomia interna en el tratamiento de la estenosis de uretra bulbar (EUB) / Internal urethrotomy as a treatment of the bulbar urethral stricture

Objetivo: Determinar el porcentaje de reestenosis posterior al tratamiento de la EUB con uretrotomía interna. Material y Métodos: Fueron tratados un total de 31 pacientes portadores de EUB cuya longitud fuera igual o menor de 0,5 cm, en los cuales el seguimiento promedio fue de 25,3 meses. Se excluyeron aquellos con áreas de espongiofibrosis, tratamiento previo por su estenosis o en tratamiento por carcinoma transicional de vejiga. En al 90 por ciento de los casos el procedimiento se realizó en forma ambulatoria bajo anestesia local. Resultados: El 58 por ciento de los pacientes presentaromn estenosis postoperatorias en un tiempo promedio de 5,4 meses.
