RESUMO

OBJECTIVES: To study the clinical, diagnostic, and therapeutic features of upper urinary tract tumors. METHODS: We perform a retrospective study of upper urinary tract tumors treated in our Department at Clinica La Luz Madrid between 1995 and 2008. RESULTS: We treated 42 tumors in 40 patients. Mean age was 64 years; there were 29 males and 11 females. Macroscopic hematuria was the most frequent clinical presentation, in 45% of the cases, and the imaging diagnostic test most frequently used was intravenous urogram (62,5%).There were more tumors on the right side (20 cases( than the left side (18 case), 2 cases were bilateral. Distal ureter was the most frequent site.27,5% of the patients presented associated bladder tumors. The most frequently used therapy was laser endoscopic resection. 5 patients required a second operation due to recurrence and 2 more a programmed second procedure due to incomplete resection; 7 cases presented postoperative complications. 70%of the tumors were superficial. 40%of the cases underwent local chemotherapy with weekly bladder instillations of Mitomycin C for 8 weeks. Recurrence rate was 20% and mortality 10%. CONCLUSIONS: Upper urinary tract tumors keep being a rare entity appearing in mid-advanced ages. Radical nephroureterectomy with excision of bladder cuff has been the treatment of choice for years, but in recent years endoscopic treatment is gaining more importance and is showing good results in selected cases.

RESUMO

OBJETIVO: Estudiar la clínica, el diagnostico y el tratamiento de los tumores de tracto urinario superior.MÉTODOS: Realizamos un estudio retrospectivo de los tumores de tracto urinario superior tratados en nuestro centro, Clínica La Luz Madrid, entre el 1995 y el 2008.RESULTADOS: Tratamos 42 tumores en 40 pacientes. La edad media fue de 64 años y encontramos 29 varones frente a 11 mujeres.El debut clínico más frecuente fue la hematuria macroscópica en el 45% de los casos y el método diagnostico que más se utilizó fue la urografía intravenosa (62,5%).El lado más afectado fue el derecho (20 casos frente a 18 del lado izquierdo) y en dos casos el tumor se presentó de forma bilateral. La región más afectada fue el uréter distal. El 27,5% de los pacientes presentaron asociado tumor vesical.La terapia más utilizada fue la resección láser endoscópica, 5 pacientes precisaron una segunda intervención por recidiva y dos programada por resección incompleta, siete casos presentaron complicaciones post intervención. El 70% de los tumores fue superficial. El 40% de los casos fue sometido a quimioterapia local con instilaciones endovesicales con Mytomicina C a ritmo semanal por 8 semanas. La tasa de recidiva fue del 20% y la de mortalidad del 10%.CONCLUSIONES: Los tumores del tracto urinario superior siguen siendo una entidad poco frecuente que aparece en la edad media avanzada de la vida. Durante años el tratamiento de elección ha sido la nefroureterectomía radical con resección de rodete vesical, en estos últimos años el tratamiento endoscópico está tomando cada vez más importancia y está dando buenos resultados en casos bien selecionados(AU)

RESUMO

Objetivo: Valorar las aportaciones del láser, fundamentalmente de holmio, en el tratamiento endourológico de la litiasis ureteral. Método: Analizamos la experiencia acumulada en 154 tratamientos endourológicos con láser holmio de litiasis ubicadas a nivel ureteral, realizado de forma continuada en nuestra Unidad desde junio 2005 a diciembre 2007. Resultados: Se consiguió la fragmentación litiásica en el 100% de los casos. El uso asociado de la pinza de rama larga al láser de holmio, nos permitió alcanzar tasas de ausencia de litiasis residual en el 91% de los pacientes. Conclusiones: El tratamiento de la litiasis ureteral se ha beneficiado de los procedimientos endoscópicos, siendo el láser de holmio la fuente de energía de elección en el momento actual. La tasa de fragmentation alcanzada fue del 100%. Las complicaciones fueron escasas y en ningún momento de importancia (AU)


Objectives: To evaluate the contribution of laser, mainly holmium laser, to the endourological treatment of ureteral lithiasis. Methods: We analyze our experience in 154 endourological treatments of ureteral lithiasis with holmium laser performed in our Unit from June 2005 to December 2007. Results: Stone fragmentation was achieved in 100% of the cases. The use of long jaw forceps associated with the holmium laser enabled us to reach a stone free rate of 91%. Conclusions: The treatment of ureteral lithiasis has benefit from the development of endoscopic procedures, being the holmium laser the energy source of choice nowadays. The fragmentation rate was 100%. Complications were rare and never important (AU)

RESUMO

OBJECTIVES: After the description and standardization of the technique of ureteroscopy in 1979, several methods to obtain a nontraumatic, simple, efficient and fast ureteral access have been developed. The hydraulic expansion of the ureter was possible in 1986, with the development of ureteromat. We evaluate the effectiveness of hydraulic ureteral expansion (Ureteromat) for ureteral access and the later endoscopic procedures. METHOD: The last 100 ureteroscopy carried out from February to October 2006 were evaluated. We used a semi-rigid 9.8 Fr. ureteroscope and hydraulic expansion (Ureteromat) was performed in the same way in all procedures since 1986. RESULTS: Of the total of cases, 92 were indicated for lithiasic pathology, 7 were exploratory and 1 for ureteral stricture. In 94 patients the procedure was carried out with hydraulic expansion alone, in 2 cases we used a balloon catheter, in 3 patients expansion of the meatus was done with forceps and 1 procedure was not possible due to an ureteral stop. CONCLUSION: The Ureteromat pump guarantees an excellent hydraulic expansion of the ureteral meatus and the passage of the intramural ureter. The visibility is very good at any moment of the procedure, making ureteroscopy a simple, effective, non traumatic and fast method.

RESUMO

Objetivo: Tras la descripción y estandarización de la técnica de ureteroscopia en 1979, se han desarrollado varios métodos para conseguir un acceso ureteral no traumático, simple, eficiente y rápido. La dilatación hidráulica del uréter fue posible en 1986, con el desarrollo de Ureteromat. Se evaluó la efectividad de la dilatación ureteral hidráulica (Ureteromat) para el acceso ureteral y el procedimiento endoscopico posterior. Método: Se evaluaron las 100 últimas ureteroscopias llevadas a cabo desde febrero hasta octubre del 2006. En todas las ureteroscopias se utilizo un ureteroscopio semirígido de 9.8 Fr y en todos los procedimientos se realizó dilatación hidráulica (Ureteromat) como se viene realizando desde 1986. Resultados: Del total de los casos, 92 se indicaron por patología litiasica, 7 fueron exploradoras y 1 por estrechez ureteral. En 94 pacientes el procedimiento se llevó a cabo con dilatación hidráulica exclusivamente, en 2 casos se realizó además dilatación con catéter balón, en 3 pacientes dilatación del meato con pinza y sólo en 1 procedimiento no fué posible por un stop ureteral. Conclusión: La bomba de irrigación Ureteromat garantiza una excelente dilatación hidráulica del meato ureteral y del trayecto intramural del uréter. La visibilidad es muy buena en todo momento, haciendo de la ureteroscopia un método simple, eficaz, no traumático y rápido (AU)

RESUMO

Prostate cancer is currently one of the main causes of urological practice workload. Patients with negative prostate biopsies may pose serious problems to the urologist in the decision making process for follow-up due to the lack of definitive data in the follow-up algorithm. MRI spectroscopy seems to open a diagnostic window evaluating prostatic metabolic changes. The performance of perineal prostatic biopsy with stabilizer and template enables selective biopsy of the suspect voxels following the spectroscopic study, simulating the Rubick's cube.

RESUMO

El cáncer de próstata supone en el momento actual, uno de los capítulos de actuación urológica mas importante. El paciente biopsiado con resultado negativo para tumor, supone un serio «problema» para el urólogo en cuanto a la toma de decisiones, para su seguimiento ante la falta de datos concluyentes en el algoritmo de seguimiento. La espectrospia asociada a RMN parece abrir una ventana diagnóstica al valorar los cambios metabólicos prostáticos. La realización de biopsia prostática mediante acceso transperineal, con sistema estabilizador y templete permite la punción selectiva de los voxels sospechosos en el estudio espectroscópico, simulando un cubo de Rubick (AU)

RESUMO

OBJECTIVE: To analyze the results obtained with antegrade endopyelotomy and compare them with those reported in the literature. METHODS: 16 patients with ureteropelvic junction (UPJ) obstruction treated by antegrade endopyelotomy were evaluated. RESULTS: In our series the success rate was 81.3%. Avulsion of the UPJ was observed in one patient and required conversion into an Anderson-Hynes pyeloplasty. Two cases of re-stenosis were diagnosed within the first three months. CONCLUSIONS: Long-term follow-up shows that antegrade endopyelotomy can be indicated as the treatment of choice for primary and secondary UPJ strictures.
