Fulguración con láser de la recidiva de tumores vesicales superficiales bajo anestesia local: diseño de procesos / Laser fulguration of superficial bladder tumor recurrence under local anesthesia. design process

Introduction: The process design is one of the most interesting tools to ensure the quality of health care before the start of an activity. Although the gold standard treatment of superficial bladder tumors remains transurethral resection (TUR), the onset of laser energy source with better endourological systems allows us to adopt alternative therapies. The aim of this pilot study is to describe the design and protocol in 37 patients with a novel process consisting of outpatient treatment under local anesthesia of bladder tumors with holmium laser. Material and Methods: Pilot study includes 37 patients between January 2012 and December 2013, for the development of a process of holmium laser bladder fulguration without anesthetic infiltration in outpatient study. It analyzes and studies the procedure tolerance, development of immediate complications, visual analog scale (VAS) of pain, patient satisfaction, hospital stays avoided, problems during the application process and development. Results: The mean age of the patients was 69.2 +/- 10.3 years, 100 percent of patients prefer this procedure instead conventional transurethral resection and VAS rating presenting ≤ 3. There were no important complications. Only one patient was admitted at hospital due to hematuria resolved without surgical treatment. Conclusions: The development and implementation of fulguration of superficial papillary bladder tumors with holmium laser process is simple, well tolerated, ambulatory and without complications, with no need of hospital stay.

Introducción: El diseño de procesos es una de las herramientas de mayor interés para asegurar la calidad de la asistencia sanitaria antes del comienzo de una determinada actividad. Aunque el gold standard del tratamiento de los tumores vesicales superficiales sigue siendo la resección transuretral (RTU), la aparición de la fuente de energía láser con mejores medios endourológicos nos permite adoptar otras alternativas terapéuticas. El objetivo de este estudio piloto es describir el diseño y protocolo en 37 pacientes de un proceso novedoso consistente en el tratamiento en régimen ambulatorio y bajo anestesia local intravesical de los tumores de vejiga con láser de holmium. Material y Métodos: Estudio piloto que incluye 37 pacientes entre enero de 2012 y diciembre de 2013, para la elaboración de un proceso de fulguración vesical con láser de holmium sin infiltración anestésica en régimen ambulatorio. Se analiza y estudia tolerancia al procedimiento, desarrollo de complicaciones inmediatas, escala visual analógica (EVA) del dolor, satisfacción del paciente, estancias hospitalarias evitadas, problemas durante la aplicación del proceso y desarrollo del mismo. Resultados: La edad media de los pacientes fue 69,2 +/- 10,3 años, presentando puntuación EVA ≤ 3. No existieron complicaciones importantes. Hubo un ingreso por hematuria tardía que se resolvió de forma conservadora. Conclusiones: La elaboración y aplicación del proceso de fulguración de tumores vesicales papilares superficiales con láser holmium es una técnica sencilla, con buena tolerancia, ambulatoria y sin complicaciones de interés, con eliminación de estancias hospitalarias.

Association between the interaction polymorphisms of interleukin-l0 and smoking on patients with bladder cancer risk from a case-control study / 中华流行病学杂志

Objective To investigate the relationship between both polymorphisms of interleukin-10 (IL-10),smoking and the susceptibility to bladder cancer.Methods A case-control study was conducted to study the promoter polymorphisms of IL-10 gene by allele specific PCR amplification (AS-PCR) and to explore the possible genetic and environmental factors on bladder cancer,based on data from a hospital which included 400 patients with bladder cancer and another 400 healthy controls.Results The genotypes of IL-10 gene might be associated with the susceptibility to bladder cancer.Homozygous mutant of IL-10 gene at the point of 1082,819 and 592 could enhance the risk of bladder cancer (OR value is 2.058,1.979,1.979,respectively).No statistically significant correlation was found between the divergence of IL-10 genotype and the different clinical stages and pathological grade of bladder cancer (P＞0.05).Interactions were noticed between polymorphisms in IL-10 gene and their correlation with smoking on bladder cancer.The positive interaction of 1082 site homozygous variant (AA),819 site homozygous variant (TT),592 site homozygous variant (AA) and smoking were revealed in the occurrence rates of bladder cancer (OR=2.264,γ=l0.213;OR=2.438,γ=6.750; OR=2.438,y=6.750).Conclusion Our research findings showed that the significant interactions between IL-10 gene with homozygous mutant and smoking might increase the risk of bladder cancer.

Cistectomia radical videolaparoscópica com neobexiga ileal ortotópica: experiência inicial / Laparoscopy radical cystectomy with ileal orthotopic blad - der: A preliminary experience

Apesar de ser o padrão-ouro no tratamento dos tumores invasivos de bexiga, a cistoprostatectomia ainda apresenta significativo impacto na qualidade de vida dos pacientes. As abordagens minimamente invasivas têm ganhado cada vez mais espaço no tratamento das neoplasias urológicas. Ainda são poucas as séries na literatura sobre o acesso videolaparoscópico para confecção de neobexiga ortotópica após a cistoprostatectomia radical. Relata-se um caso de câncer invasor de bexiga tratado de forma laparoscópica com ótimo resultado. As vantagens do acesso laparoscópico, assim como alguns detalhes técnicos, são discutidas.

Although it is not considered a gold standard in treating invasive bladder tumors, cystoprostatectomy still has significant impacts on patients? life quality. The minimally invasive approaches have gained importance in the treatment of bladder neoplasia. There are sill few reports on the use of laparoscopy for providing orthotopic bladder upon radical cystoprostatectomy. This is a case report of invasive bladder cancer that was treated with laparoscopy and yielded optimal result. The advantages of laparoscopy and some technical details are herein discussed.
