[Urachal cyst presenting as acute urinary retention]. / Retención aguda de orina, "RAO", como presentación de quiste de uraco.

About 2% of adults have an urachal cyst. The diagnosis is usually made due to its clinical complications. We report an inusual case of acute urinary retention due to an urachal cyst, with hipogastric pain and anuria as initial syntoms.

[Treatment of female stress urinary incontinence with TVT system (tension-free vaginal tape): complications in our first 100 cases]. / Tratamiento de la incontinencia urinaria de esfuerzo con el sistema TVT: complicaciones en nuestros primeros 100 casos.

INTRODUCTION: The TVT system is the most common surgical technique of female stress urinary incontinence, because of the simplicity. good clinical results and rare complications. MATERIAL AND METHODS: From april, 1999 to march. 2004, it has been done in our department 100 TVT systems with the revision of the result over the six following months. The average follow-up rate was 10.36 months (R: 1-54 months) and looses mean the 11% of the cases. All the patients presented stress incontinence and their average age was 56.6 years old (30-80). The 12% of the cases have been previously operated of urinary incontinence. 21 patients presented previous surgery of pelvic floor. In the 17% of the cases, TVT systems was associated to another surgical technique: 15% of them was operated of cystocele, 1% of them had surgical correction of rectocele, 1% of them had a strong surgery of pelvic floor, that included TVT system, correction of pelvic floor and hysterectomy. RESULTS: We obtained 65% of successful cases, defined as objective confirmation of absence of looses from the observer and the subjective reference of the patient: 17% of clear improvement (clear decrease of looses from the patient and subjective improvement) and 7% of failure of the technique. The total percentage of appearance of novo post-surgery urgency is 9%. There were complications in the 12% of the cases: there were three cases of bladder perforation, two of them intra-operative and one of them deferred and associated to an infection of surgical wound; another three cases of residue in the immediate post-operative that were resolved with bladder catheterization: one case of acute urinary retention that was treated with bladder catheterization with suprapubic cistostomy: one case of chemical peritonitis corrected with a conservative treatment; two cases of vaginal extrusion of sling, which were resolved with the section of the outer sling; one patient presented a hipogastric hematoma resolved with conservative measures: and one patient presented pelvic discomfort with spontaneous resolution. CONCLUSIONS: We consider the TVT system as an effective surgical technique in the treatment of the female stress urinary incontinence. It is a simple technique with a short stay in the hospital and rare complications.

Tratamiento de la incontinencia urinaria de esfuerzo con el sistema TVT: complicaciones en nuestros primeros 100 casos / Treatment of female stress urinary incontinence with TVT system (tension-free vaginal tape): complications in our first 100 cases

Introducción: El sistema TVT (Tension-free Vaginal Tape) es la técnica quirúrgica de elección en los últimos años de la incontinencia urinaria de esfuerzo femenina (IUE), dada la facilidad de la técnica, buenos resultados clínicos y escasas complicaciones. Material y métodos: Desde Abril de 1999 a Marzo 2004 se han implantado en nuestro servicio 100 sistemas TVT con revisión de los resultados a los 6 meses, y un seguimiento medio de 10,36 meses (R: 1-54 meses), con una pérdida de seguimiento en el 11% de los casos. Todas las mujeres estudiadas presentaban incontinencia de esfuerzo, siendo la edad media de 56,5 años (30-80). Un 12% habían sido intervenidas previamente de IUE. Presentan cirugía previa del suelo pélvico 21 pacientes. En un 17% de los casos se realizó TVT asociado a otra técnica quirúrgica: 15% cistorrafia anterior, 1% corrección de rectocele, 1% cirugía compleja del suelo pélvico que incluye TVT, corrección de cistocele e histerectomía. Resultados: Obtenemos un 65% de éxitos (comprobación objetiva de la ausencia de escape por parte del médico y referencia subjetiva de la paciente), un 17% de mejoría (disminución clara de escapes por parte de la paciente y mejoría subjetiva) y un 7% de fracaso de la técnica. El porcentaje global de aparición de urgencia de novo posquirúrgica es del 9%. Existieron un 12% de complicaciones; 3 casos(3%) de perforación vesical, 2 de ellos intraoperatorios y 1 diferida junto con infección de la herida quirúrgica; 3 episodios (3%) de residuos altos en el postoperatorio inmediato, resueltos con autosondajes, y un caso de RAO (1%) dado de alta con cistostomía suprapúbica; un caso (1%) de peritonitis química tras retirada de talla vesical resuelta con tratamiento conservador; dos casos (2%) de extrusión vaginal de la bandeleta, con sección de la porción de malla exteriorizada en ambos casos; un (1%) paciente presenta hematoma hipogástrico que se resuelve con medidas conservadoras; un 1 % de los pacientes (1 caso) presentó molestias pélvicas subcrónicas con resolución espontánea. Conclusiones: Consideramos el sistema TVT una técnica quirúrgica eficaz en el tratamiento de la incontinencia urinaria femenina de esfuerzo. Es una técnica sencilla, con baja estancia hospitalaria y escasas complicaciones (AU)

[Surgical stratification of renal carcinoma with extension into inferior vena cava]. / Estratégia quirúirgica en el carcinoma de células renales con extensión a la circulación venosa.

Renal cell carcinoma with inferior vena cava thrombus is relatively uncommon and complicates radical nefrectomy. During the past twenty years our hospital have substantially contributed to the surgical stratification of renal cell carcinoma with extension into inferior vena cava through different techniques. The reason for this article is to discuss the mote efficient and appropiate surgical technique for this pathology. We believe that the diagnosis of vena caval invasion and level of tumoral extension is based on radiological examinations and it is crucial for the success of the surgery. We consider that the use of vena caval filter applied preoperatively could prevent the risk of thromboembolism during and after the surgery. The use of prosthetic grafts is unusual, because the long standing obstruction caused by the tumor thrombus will develope extensive collateral circulation which works as a natural veno-venous bypass. Finally, we try to avoid the use of veno-venous and cardiopulmonar bypass with or without complete hypothermic circulatory arrest due to the high association with adverse outcomes and mortality.

Estratégia quirúrgica en el carcinoma de células renales con extensión a la circulación venosa / Surgical stratification of renal carcinoma with extension into inferior vena cava

El carcinoma de células renales con trombo en vena cava inferior es una patología relativamente rara, que complica la nefrectomía radical. Durante los pasados veinte años nuestro hospital ha contribuido sustancialmente a la estratificación quirúrgica del carcinoma de células renales con extensión a la vena cava a través de diferentes técnicas. El objetivo de este artículo es describir las diferentes estrategias quirúrgicas necesarias y más apropiadas para el tratamiento de los distintos niveles del trombo tumoral. Consideramos que el diagnóstico de la invasión de la vena cava por el tumor y el nivel de extensión tumoral están basados en exámenes radiológicos, los cuales son determinantes a la hora del planteamiento quirúrgico y éxito de la cirugía. Somos partidarios del uso de filtros de vena cava colocados. Preoperatoriamente para prevenir el riesgo de tromboembolismos pulmonares durante y después de la cirugía. El uso de prótesis de cava es excepcional, debido a que la obstrucción crónica producida por el trombo tumoral, permitirá el desarrollo de una extensa circulación colateral que actuará como un bypass veno-venoso. Por último, intentamos evitar el uso de bypass veno-venoso o bypass cardiopulmonar con o sin hipotermia y parada cardiocirculatoria, debido a la alta morbimortalidad que conllevan (AU)

Neuromodulación de raíces sacras. Experiencia de nuestro centro 1998-2003. A propósito de 18 implantes definitivos de neuromodulación / Sacral root neuromodulation. Experience in our site: 1998-2003, concerning 18 definite neuromodulation implants

OBJETIVO: La neuromodulacion de raíces sacras es una técnica eficaz para el tratamiento de la Disfunción Miccional Crónica (DMC), refractaria a tratamientos convencionales. En la actualidad están surgiendo nuevas indicaciones en el ámbito urológico, como el dolor pélvico crónico y la cistitis intersticial. Diversos grupos de cirujanos digestivos están optando por esta técnica para el tratamiento de patología rectal (estreñimiento, disfunción esfinteriana). Este trabajo aporta nuestra experiencia en el tratamiento de pacientes con DMC y los resultados comparativos al año del implante de todos los pacientes. MATERIAL Y MÉTODOS: Desde diciembre de 1998 a julio del 2003 hemos realizados 18 implantes definitivos de neuromodulacion. La indicación principal fue la DMC, en un 62,5% de los pacientes. El seguimiento de los pacientes lo realizamos al mes, tres meses, y posteriormente cada seis meses. Este se realiza mediante diario miccional y cuestionario de calidad de vida. El implante del electrodo en los 16 primeros pacientes se ha realizado mediante cirugía abierta, mientras que los 2 siguientes se ha colocado el electrodo mediante técnica percutánea, utilizando el kit “Tined Lead”. RESULTADOS: Comparamos resultados al año del implante en todos los pacientes. Se han realizado 18 implantes de neuromodulación de los cuales 14 (77,7%) han sido en mujeres y 4 (22,3%) en varones. La edad media es de 52,56 años. La indicación del implante en un 72,2% de los pacientes fue por DMC, un 22,1% por incontinencia mixta (urinaria y fecal), y un 5,5% fue por cistopatía intersticial. La mejoría de los síntomas al año del implante, medidos por el calendario miccional y el cuestionario de calidad de vida fue de 76,4%. La mejoría clínica fue mayor en los pacientes con síntomas de urgencia, que los pacientes con predominio de la sintomatología de vaciado

OBJECTIVE: Sacral root neuromodulation is an effective technique for the treatment of Chronic Micturition Dysfunction (CMD) refractory to conventional therapy. New indications such as chronic pelvic pain and interstitial cystitis are currently making their way within the urologic setting. Several groups of gastric surgeons are now choosing this technique for the management of rectal diseases (constipation, sphincter dysfunction). This paper contributes our experience in the treatment of patients with CMD and the comparative results at one year from implant in all patients. MATERIAL AND METHODS: From December 1998 through July 2003, 18 neuromodulation definite implants were performed. The main indication was CMD in 62.5% patients. Follow up of patients was done at one month and three months, and every six months thereafter. Follow up is conducted through a micturition diary and QoL questionnaire. Electrode implant in the first 16 patients was achieved by open surgery. The next 2 patients had the electrode placed by a percutaneous technique using the “Tined Lead” kit. RESULTS: Results at one year after implant were compared in all patients. The total number of neuromodulation implants placed was 18, 14 (77.7%) of which were women and 4 (22.3%) men. Mean age was 52.56 years. Implant indication was CMD in 72.2% patients, mixed incontinence (urinary and faecal) in 22.1%, and interstitial cystic disease in 5.5%. Symptoms improvement at one year from implant, as determined by a micturition diary and QoL questionnaire was 76.4%. Clinical improvement was greater in patients with urgency symptoms than in patients with predominance of voiding symptoms

[Metastasis in renal graft of primary renal adenocarcinoma]. / Metastasis en injerto renal de adenocarcinoma renal primario.

Acquired cystic renal disease (A.C.R.D.) is a risk factor for the development of renal carcinoma in the patient's own kidney after renal transplant (R.T.), development of a primitive tumor in the renal graft is infrequent, but the presence of metastasis of an epithelial tumor is very rare. This is the second case reported in the literature of metastasis of an epithelial tumor in the renal graft and the first case described of renal cell carcinoma metastasis (R.C.C.) in the renal graft. This paper describes the case of a patient with a normally functioning renal transplant and A.C.R.D. who develops RCC in his own kidney, with metastasis in the renal graft.

Metastasis en injerto renal de adenocarcinoma renal primario / Metastasis in renal graft of primary renal adenocarcinoma

La enfermedad renal quística adquirida (E.R.Q.A), es un factor de riesgo para el desarrollo de carcinoma renal en los riñones propios, tras el trasplante renal (T.R.). El desarrollo de un tumor primitivo del injerto renal es infrecuente. De otro lado, la incidencia de tumor primitivo en el injerto renal es infrecuente, pero la presencia de metástasis en el de un tumor epitelial es excepcional, siendo este el segundo caso de literatura de metástasis de tumor epitelial en injerto renal; y el primer caso descrito de metástasis de carcinoma de células renales (C.C.R.), sobre injerto renal. El caso de un paciente con TR normofuncionante y ERQA que desarrolla CCR en riñón propio, con metástasis sobre el injerto renal

[Primary testicular lymphoma. Report of a new case and review of the literature]. / Linfoma testicular primario. Aportación de un nuevo caso y revisión de la literatura.

Primary testicular lymphoma is an uncommon testicular tumour that accounts for no more than 9% of all testicular tumours in those series with higher incidence; testicular lymphoma as haematopoietic tumours are also rare accounting for just 1% of all lymphomas; but due to their highly malignant histopathology they may become highly aggressive tumours. Patient age at presentation is over 60 years old which makes it the most frequent tumour for this age group. There is no standard protocol to treat this malignancy due to lack of extensive series. We contribute one case and make a literature review discussing the current therapeutic trends for this disease.

Linfoma testicular primario. Aportación de un nuevo caso y revisión de la literatura / Primary testicular lymphoma. Contribution of one case and literature review

El linfoma testicular primario es un tumor testicular infrecuente, suponiendo no más del 9 por ciento de los tumores testiculares en las series con mayor incidencia; a su vez el linfoma testicular como tumor hematopoyético es infrecuente, con una incidencia del 1 por ciento de los linfomas, pero debido a su histopatología en la mayoría de los casos de alta malignidad, les hace ser de los tumores testiculares más agresivos. La edad de aparición es por encima de los 60 años, convirtiéndose en el tumor más frecuente para este grupo de edad. La falta de series amplias, hace que no exista un protocolo establecido para el tratamiento de esta patología. Presentamos un nuevo caso, realizando revisión de la bibliografía presentando las tendencias terapéuticas actuales para este tipo de patología (AU)
