Magnetic resonance imaging to evaluate anterior pelvic prolapse: H line is the key.

INTRODUCTION: The aim of the study is to compare clinical staging of anterior pelvic prolapse with magnetic resonance imaging (MRI) staging, using the pubococcygeal line (PCL), the midpubic line (MPL), and the H line as reference lines. Moreover, we aim to analyze interrater reliability of each reference line. MATERIAL AND METHODS: Forty-two women with pelvic organ prolapse (POP) symptoms were studied using the pelvic organ prolapse quantification on physical examination. Two different observers calculated anterior POP using the three MRI reference lines, retrospectively. Agreement between MRI and clinical staging was estimated using Pearson correlation for the quantitative measurements and kappa index for the stages. Interrater reliability was estimated using the intraclass correlation coefficient (ICC). RESULTS: Correlation between physical examination and the H line was high by both observers (r = 0.86 and r = 0.76, p < 0.01). The correlation was lower using MPL (r = 0.76 and r = 0.65, p < 0.01). The results of comparing MRI staging and physical examination were: κ = 0.618 and κ = 0.602 for the H line, κ = 0.273 and κ = 0.267 for MPL and κ = -0.105 and κ = -0.140 for PCL. The results of interrater reliability were: ICC of 0.968 for the H line, ICC of 0.788 for MPL, and ICC of 0.737 for PCL. CONCLUSION: Anterior POP staging using MRI H line as a reference presents a better agreement with clinical staging than PCL or MPL. The H line has better interrater reliability. The H line could replace the current lines.

[Urinary tract hemangiopericytoma treated with radical surgery and neoadjuvant chemotherapy. Report of two cases.] / Hemangiopericitoma en la via urinaria tratados con cirugía radical y quimioterapia neoadyuvante. A propósito de dos casos.

OBJECTIVE: Hemangiopericytoma is a tumor of vascular origin. It is very rare in the prostate. They are generally aggressive tumors. Currently, the treatment of choice is radical surgery. In the literature, there are less than 50 cases described, and neoadjuvant treatment has not been reported in any article. This treatment presents positive responses in another type of sarcomas. Our goal is to report two cases of malignant hemangiopericytoma. The first case was treated with radical surgery and the second case was treated with neoadjuvant chemotherapy before surgery. METHODS: The first case is a 40 year old male. Obstructive urinary symptoms were his first symptoms. A prostate mass with tumor characteristics was seen on ultrasound. After transrectal biopsy, he was diagnosed with hemangiopericitoma. Because the tumor size, neoadjuvant chemotherapeutic prior to radical surgery was decided. The second case is a 77 year old male with an incidental diagnosis of renal mass. After radical nephrectomy, he was diagnosed with hemangiopericitoma. He did not receive adjuvant chemotherapy. RESULTS: In the first case, after neoadjuvant therapy, tumor size was reduced significantly. A pelvic exenteration with radical cystoprostatectomy and rectal resection and Bricker type urinary diversion and colostomy were carried out. In the second case controls after radical nephrectomy were correct and he did not need any treatment. CONCLUSIONS: In urinary tumors, the prostate hemangiopericytoma is a rare entity. Currently, neoadjuvant chemotherapy is not established as treatment for these tumors. For other sarcomas neoadyuvant treatment has good response. In our case, a good result was obtained with neoadjuvant chemotheraphy before surgery. However, a greater number of cases are necessary to establish the use of neoadjuvant chemotherapy in urinary hemangiopericytomas.

OBJETIVO: El hemangiopericitoma es un tumor de origen vascular muy infrecuente en la próstata. Son tumores de características agresivas y actualmente el tratamiento de elección es la cirugía radical. En la literatura existen descritos menos de 50 casos de hemangiopericitomas, y ninguno con tratamiento neoadyuvante. Dicho tratamiento neoadyuvante está descrito en otro tipo de sarcomas con buenas respuestas. Presentamos dos casos de un hemangiopericitoma maligno, uno tratado sólo con cirugía radical y otro con neoadyuvancia quimioterápica previa a la cirugía radical.MATERIAL Y MÉTODOS: El primer caso es un varón de 40 años con síntomas urinarios obstructivos. Se diagnosticó de hemangiopericitoma tras realización de biopsia transrectal. Se decidió neoadyuvancia quimioterápica previa a la cirugía. El segundo paciente es un varón de 74 años con hallazgo accidental de masa renal. Tras nefrectomía radical se diagnosticó de hemangiopericitoma. RESULTADOS: Tras la neoadyuvancia, en el primer paciente, se realizó una cistoprostatectomía radical y una resección de recto con derivación urinaria tipo Bricker y colostomía. El segundo paciente no precisó tratamiento adyuvante tras la cirugía radical. CONCLUSIONES: El hemangiopericitoma es una entidad rara en los tumores urinarios. Actualmente la neoadyuvancia quimioterápica no está establecida como pilar del tratamiento de estos tumores, aunque en otros campos donde los sarcomas son más frecuentes, si que se objetiva mejor respuesta. En nuestro caso obtuvimos una buena respuesta con dicha neoadyuvancia previa a la cirugía, aunque es necesario un mayor seguimiento a una mayor cohorte de pacientes para establecer el uso de la quimioterapia neoadyuvante en los hemangiopericitomas urinarios.

[Report of two cases of malignant mesothelioma of the tunica vaginalis.] / Analisis de dos casos de mesotelioma maligno de la túnica vaginal.

OBJECTIVE: Paratesticular mesothelioma isan infrequent tumor and only 250 cases have been published.It originates in the scrotal tunica vaginalis. It represents0.3-1.4% of mesotheliomas and it predominates inpatients with history of asbestos exposure and old age. Itsdiagnosis is usually casual. Our objective is to present thecases that occurred in our service with malignant paratesticularmesothelioma and to carry out a review of the currentliterature on this pathology. METHODS: We report two cases diagnosed with malignantparatesticular mesothelioma that happened in the lasttwo years. RESULT: The first case was a 73-year-old male with asymptomatichydrocele. The second was a 57-year-oldmale who had testicular pain and hydrocele. Both werediagnosed of mesothelioma after hydrocelectomy. The firsttreatment was radical orchiectomy in both cases. The firstpatient did not need more treatments. The second patientpresented pulmonary nodules, lymphadenopathy and localrelapse, which was treated with chemotherapy and localresection. CONCLUSION: Paratesticular mesothelioma is an infrequenttumor. Scrotal mass associated with hydrocele is thetypical form of presentation. Surgical treatment consists ofradical orchiectomy. They have poor prognosis because inmost cases there is rapid local and dissemination.

OBJETIVO: El mesotelioma paratesticular es  un tumor infrecuente, con menos de 250 casos publicados, originado en la túnica vaginal escrotal. Representa el 0,3-1,4% de los mesoteliomas. Predomina en pacientes añosos, con la exposición al asbesto y su diagnóstico sueleser casual. Nuestro objetivo es presentar dos casos ocurridos en nuestro servicio con mesotelioma paratesticular maligno y realizar una revisión de la literatura actual sobre dicha patologia.MÉTODO: Aportamos dos casos diagnosticados de mesotelioma paratesticular maligno acontecidos en nuestro servicio durante los últimos dos años. RESULTADO: El primer caso es un varón de 73 años que debutó con hidrocele sin dolor. El segundó es un varón de 57 años que inició su clínica con un cuadro de dolor testicular e hidrocele. En ambos se diagnostica de mesotelioma maligno de la túnica vaginal tras hidrocelectomía. Se realiza como tratamiento inicial una orquiectomía radical en ambos pacientes. El primer paciente no precisó ningún tratamiento adicional. El segundo paciente presentó nódulos pulmonares y adenopatías junto con recidiva local, que se trató con quimioterapia y resección local.CONCLUSIÓN: El mesotelioma paratesticular es un tumor infrecuente, sin una clínica especifica. Su forma típica de presentación es una masa escrotal indolora asociada a hidrocele.El tratamiento quirúrgico consiste en orquiectomía radical. En la mayoría de los casos existe una rápida diseminación local y a distancia que otorgan a estos tumores un mal pronóstico.
