Guía práctica para el manejo y tratamiento ante la cistitis radical / Practical treatment approach of radiation induced cystitis

Objetivo: Establecer una pauta de actuación y un algoritmo terapéutico ante la aparición de hematuria en pacientes con antecedentes de radioterapia pélvica, revisando para ello las diferentes opciones de tratamiento reflejadas en la literatura médica. Material y métodos: A través de PubMed se realiza una revisión bibliográfica de artículos relacionados con la cistitis rádica, incluyendo términos de búsqueda referidos a las diferentes opciones de tratamiento: ácido hialurónico endovesical; estrógenos conjugados, pentosan polisulfato, ácido aminocaproico oral, factor VIIa recombinante, cámara hiperbárica, embolización, aluminio endovesical, balón Helmstein y formolización. Se limita la búsqueda a publicaciones en castellano e inglés y se excluyen aquellas referidas a la experimentación animal. Resultados: Se expone cada una de las opciones citadas, haciendo referencia al mecanismo de acción, pauta y dosis de administración, efectos secundarios y prevención de los mismos si es posible así como eficacia del tratamiento. Tras conseguir estabilizar hemodinamicamente al paciente y descartar la presencia de lesiones neoformativas vesicales y/o hematurias originadas en tramo urinario superior, se debe iniciar un tratamiento escalonado. Conclusiones: El conocer diferentes opciones de tratamiento y sus pautas de administración permitirá al urólogo obtener una mayor tasa de éxitos en el difícil manejo de esta patología (AU)

Objective: Establish a pattern of behavior and treatment algorithm at the onset of hematuria in patients with a previous history of pelvic radiation, checking for this different treatment options reflected in the literature. Material and methods: Through performing a PubMed literature review of articles related to IC lies, searching items includes the different treatment options: intravesical hyaluronic acid, conjugated estrogens, pentosan polysulfate, oral aminocaproic acid, recombinant factor VIIa, hyperbaric chamber, embolization, aluminum intravesical, Helmstein ball and formalin. Limits the search to english or spanish publications and excluding those related to animal experimentation. Results: Every option is exposed, referring to the physiopathology, dosage regimen and administration, side effects and treatment efficacy. Conclusions: Once patient hemodynamic stabilization is achieved, and after rule out bladder tumors injuries and /or haemathuria originating from the upper urinary tract, treatment should start rolling. To know different treatment options and patterns of administration will allow the urologist to obtain a higher rate of success in the difficult management of this condition (AU)

Can infundibular height predict the clearance of lower pole calyceal stone after extracorporeal shockwave lithotripsy?

PURPOSE: To evaluate the efficacy of extracorporeal shock wave lithotripsy (SWL) on lower calyceal calculi in relation to the renal anatomical factors and determine which of these factors can be used to select patients who will benefit from SWL. MATERIALS AND METHODS: We analyzed retrospectively 78 patients with single radiopaque lower calyceal stones treated with SWL. The patients were evaluated 3 months after lithotripsy with a simple abdominal X-ray and a kidney ultrasound scan. The success of the treatment, removal of all fragments, was correlated with renal anatomical factors measured in the pre-treatment intravenous urography: infundibulopelvic angle, lower infundibulum width, lower infundibulum length, ratio length/width, infundibulum height, and number of minor calyces in the lower calyceal group. RESULTS: Three months after SWL treatment, 39 patients were stone-free (NR group) and 39 had residual fragments (R group). Both groups presented no differences in relation to infundibulopelvic angle, width and length of the lower calyceal infundibulum, length/width ratio of the lower infundibulum or number of lower calyces. Height of the infundibulum, described as the distance between the line passing through the lowest part of the calyx containing the calculus and the highest point of the lower lip of renal pelvis, was the only parameter in which significant differences (p = 0.002) were found between the NR and R groups. CONCLUSIONS: Lower Infundibular height could be a good measurement tool for deciding which patients with lower calyceal lithiasis would benefit from SWL treatment. Height of less than 22 mm suggests a good outcome from lithotripsy.

[Arteriovenous fistula of the renal stump after nephrectomy]. / Fistula arteriovenosa renal secundaria a la ligadura en bloque del pedículo renal.

An arteriovenous fistula of the renal pedicle is a rare complication after nephrectomy. Most of cases we identify it time along after surgery. We present a case of an arteriovenous fistula of the right renal pedicle after nephrectomy done for pyonephrosis 40 years before. We comment the clinical features, treatment and evolution of the patient. We also review the actual literature.

Fístula arteriovenosa renal secundaria a la ligadura en bloque del pedículo renal / Arteriovenous fistula of the renal stump after nephrectomy

La fístula o aneurisma arteriovenoso del pedículo renal después de la nefrectomía es una complicación poco frecuente. La mayoría de las veces se diagnostica muchos años después de la cirugía. Presentamos un caso de fístula arteriovenosa del pedículo renal derecho después de una nefrectomía realizada, por pionefrosis litiásica derecha, 40 años antes. Comentamos el cuadro clínico inicial, el tratamiento y la evolución del paciente. Se revisa la literatura actual

[Cystic lymphangioma. Our experience]. / Linfangioma quístico. Nuestra experiencia.

OBJECTIVE: To comment on the most relevant aspects and to review the literature on this unusual pathology. MATERIAL AND METHODS: We present two cases of cystic lymphangioma, their clinical, diagnosis, therapy and development, and we review the actual literature. The first case is a young man with the diagnosis of cystic lymphangioma of the scrotum and pelvis. The second case is one patient with a cystic lymphangioma of the retroperitoneum. DISCUSSION: Cystic lymphangioma is a congenital lymphatic hamartoma of the lymphatic system that usually appears at childhood like a big mass at soft tissues that has a tendency to grow unless a completed excision is performed. CONCLUSIONS: There are few cases of scrotal cystic lymphangioma in the literature; they are often misdiagnosed as other common cystic scrotal conditions leading to an improper surgical approach and an incomplete surgery that predisposes later recurrence. Cystic lymphangioma of the retroperitoneum is a rare entity diagnosis in most cases as an incidentaloma.

Linfangioma quístico. Nuestra experiencia / Cystic lymphangioma. Our experience

Objetivo: Comentar los aspectos más relevantes y revisar la literatura de esta patología tan poco frecuente. Material y métodos: Presentamos dos casos de linfangioma o higroma quístico, comentando la clínica, diagnóstico, tratamiento y la evolución de éstos y, revisando la literatura actual. El primer caso es el de un joven diagnosticado de linfangioma pélvico y escrotal. El segundo es el de un paciente con linfangioma quístico retroperitoneal. Discusión: El linfangioma quístico es una malformación congénita hamartomatosa del sistema linfático que suele aparecer en la infancia a modo de grandes masas a nivel de partes blandas, con tendencia a crecer, a no ser que se extirpen de forma completa. Conclusión: Son pocos los casos descritos de higroma quístico escrotal, muchas veces diagnosticados erróneamente, como otras patologías quísticas escrotales, lo que comporta indicaciones quirúrgicas erróneas y cirugías incompletas que predisponen a la recidiva posterior. El higroma quístico retroperitoneal aislado es una patología infrecuente diagnosticada a menudo de forma incidental

[Isolated intraepithelial prostatic neoplasia and positive prostate adenocarcinoma results at repeated biopsy. Review of our series]. / Neoplasia intraepitelial prostática aislada y positividad para adenocarcinoma en la rebiopsia. Revision de nuestra serie.

OBJECTIVE: To review the incidence of isolated prostatic intraepithelial neoplasia (PIN) as well as the positive prostate cancer results in repeat biopsy in our series of transrectal biopsy of the prostate. We compare these results with the actual literature. MATERIALS AND METHODS: We review the 2.475 transrectal ultrasound guided biopsies of the prostate made in our department from January 1992 to June 2004 looking for intraepithelial neoplasia and looking in particular for isolated High-grade PIN (HGPIN). We review repeat biopsies made at this patients and the likelihood of detecting prostate cancer in them. RESULTS: The diagnosis of PIN was found in 31 biopsies, 13 of them were isolated HGPIN what means a 0.52% incidence of the total biopsies performed in our department. We performed 7 repeat biopsies of the 13 cases in a period from 3 months to 2 years after the first biopsy, and we found 3 cases of prostate cancer what means that 43% of isolated HGPIN with repeated biopsy showed prostate cancer. The mean age of the patients studied was 67 years (range 53-88). The median PSA value of the studied cases was 9.8 ng/ml. The Gleason score of the positive biopsies was always between 3 and 7. In our series, age and PSA levels did not have correlation with the positive results for prostate cancer in repeated biopsies. CONCLUSIONS: In spite of a lower number of HGPIN cases in our series, the positive for prostate cancer in repeated biopsy (43%) is similar to the incidence reported in literature so it is advisable rigorous controls and repeated biopsies for these patients.

Neoplasia intraepitelial prostática aislada y positividad para adenocarcinoma en la rebiopsia. Revisión de nuestra serie / Isolated prostatic intraepithelial neoplasia and positive prostate cancer results at repeat biopsy. Our series review

Objetivo: Revisar la incidencia de neoplasia intraepitelial prostática ( PIN ) aislada, así como la positividad para adenocarcinomaprostático de estas lesiones en la rebiopsia en nuestra serie de biopsias transrectales, comparando los resultados con la bibliografía actual. Material y Método : Hemos analizado las 2.475 biopsias prostáticas transrectales ecodirigidas realizadas en nuestro Servicio desde enero de 1992 hasta junio del 2004 en búsqueda de neoplasia intraepitelial prostática y en concreto de PIN de alto grado (PINAG) aislado, revisando las rebiopsias realizadas a estos pacientes y la probabilidad de detectar en ellas adenocarcinoma. Resultados: De un total de 31 biopsias en las que se halló el diagnóstico de PIN, 13 de ellas corresponde a PIN de alto grado aislado, lo que supone una incidencia de 0,52% del total de las biopsias realizadas en el Servicio. Se han rebiopsiado7 de estos 13 casos en un período de 3 meses a 2 años tras la primera biopsia, hallando en 3 adenocarcinoma; lo que supone que el 43 % de los PINAG aislados rebiopsiados en la serie mostraron adenocarcinoma. La edad media de los pacientes estudiados fue de 67 años (rango 53-88). El PSA medio de los pacientes estudiados fue de 9,8 ng/ml. El Gleason de las biopsias con carcinoma estuvo siempre entre 3 y 7. En nuestra muestra, la edad y los niveles de PSA no guardaban relación con la positividad a adenocarcinoma en las rebiopsias. Conclusiones: A pesar de una cifra inferior de PIN de alto grado en nuestra serie, la positividad para carcinoma en la rebiopsia (43%) es semejante a la descrita en la literatura, por lo que son aconsejables los controles rigurosos y las rebiopsias a estos pacientes (AU)
