ABSTRACT

OBJECTIVE: To report a new case of bladder schistosomiasis. METHODS: A 21-year-old patient came to our consultation with gross hematuria several weeks before, existing reddish lesions in the cystoscopy that suggested the existence of an atypical bladder tumor. RESULTS: After intense blood and urine test, ultrasonography and intravenous urography, transurethral resection of bladder was performed and the diagnosis on histological examination was bladder schistosomiasis. CONCLUSIONS: Given the high prevalence of schistosomiasis in the sub-Saharan countries and later clinical epidemiologic implications, the appearance of macro or microscopic hematuria in black race immigrants, or even any urinary symptoms, it is necessary a complete evaluation, at least with a parasitological analysis (being the bilharziasis the most probably reason). The patients who have suffered severe urinary schistosomiasis must complete long-term follow-up to prevent bladder carcinoma.

ABSTRACT

OBJETIVO: Aportación de un nuevo caso de esquistosomiasis vesical.MÉTODOS: Paciente de 21 años que acude a nuestra consulta con hematuria de varias semanas de evolución, observando en la cistoscopia la existencia de lesiones rojizas sobreelevadas que sugieren la existencia de un tumor vesical atípico.RESULTADOS: Tras ser sometido a un análisis de sangre y orina rigurosos, pruebas de imagen y, posteriormente, resección transuretral vesical el paciente es diagnosticado en el estudio anatomopatológico de esquistosomiasis vesical. CONCLUSIONES: Dada la elevada prevalencia de la esquistosomiasis en los países subsaharianos y sus posteriores implicaciones clínicoepidemiológicas, la aparición de una hematuria macro o microscópica en inmigrantes de raza negra, o incluso la aparición de cualquier sintomatología urológica, necesita una evaluación completa, al menos con un estudio parasitológico que considere la bilharziasis como la causa más probable.Los pacientes que han padecido esquistosomiasis urinaria severa deben someterse a un seguimiento a largo plazo para prevenir y detectar el desarrollo de carcinoma vesical(AU)

ABSTRACT

OBJECTIVES: To analyze the current indications for renal autotransplantation, as well as the technical features, complications and long-term follow-up of the technique. METHODS: From 1990 to 2005 we have performed autotransplantation in 10 patients, 7 adults and 3 children. The indication was established due to vascular pedicle pathology in 8 cases and ureteral lesion in 2. The cause of vascular pathology was: atherosclerotic stenosis (4), dysplastic stenosis (2), Takayasu's disease stenosis (1), and renal artery aneurysm (1). The patients with ureteral lesion had ureteral stenosis secondary to Crohn's disease in one case, initially solved by ureteral stent and subsequently obstructed by lithiasic encrustation, and ureteral avulsion in the other case. The vascular grafts employed in the 8 cases with vascular reconstruction were: hypogastric artery 7 cases, and sophena vein in one case. Ureteral reimplantation was necessary in 5 cases after bench surgery; in other five cases vascular reconstruction was performed without ureteral division. All grafts were perfused with 4 degrees C lactate ringer or Wisconsin solution and protected with surface cold ischemia. Ischemia times ranged from 42 to 89 minutes. RESULTS: Nine kidneys (90%) functioned after autotransplantation, 8 of them had immediate function, and one had delayed graft function after a six-day period of acute tubular necrosis. The kidney with arterial stenosis secondary to Takayasu's disease never functioned. The cause of graft loss was renal vein thrombosis. Postoperative mortality was zero. After a mean follow-up of 72+/- 13 months mean serum creatinine is 1.6+- 0.4 mg/dl (1.1-2.4) and 70% (7/10) of the patients have normal blood pressure without antihypertensive medication. CONCLUSIONS: Currently, renal autotransplantation, with or without extracorporeal vascular reconstruction, is a complex technique with exceptional indications, but it allows recovering renal units with vascular pathology not amenable to angioplasty or in situ revascularization. It is also a valid alternative to ileal ureteral substitution in cases of extensive ureteral lesion.

ABSTRACT

OBJECTIVES: The surgical procedures for the insertion of tension free vaginal tapes in the treatment of female stress urinary incontinence (SUI) are simple and can be done as outpatient operations. The aim of this study was to perform a budget study comparing TVT in an outpatient basis with transobturator tape (TOT) with hospital admission. METHODS: Retrospective analysis of the medical records of 23 patients undergoing surgery for SUI between October 2004 and October 2005. 13 patients were treated by TVT in an outpatient basis (group 1, Department of Urology), 10 patients were treated by TOT with hospital admission (Group 2, Department of Gynaecology). Cost analysis was carried out by the construction of a Marcov model, incorporating the time sequence of the treatment, including adverse events and results. Variables considered for the analysis: number of visits, preoperative tests, operative time, tape cost, hospital stay, unpredicted visits in the first postoperative month at the outpatient clinics or emergency room, and hospital readmissions. Statistical analysis was performed with the G-Stat software. Student's t test was used to compare quantitative variables. RESULTS: 11/13 patients (84.6%) in group 1 completed the day-surgery protocol. Mean surgical time was 61.7 min. (SD 16.2; 35-100) and 61.6 min. (SD 8.3; 50-73) for groups I and 2 respectively. Two cases in group 1 had perioperative complications (15.4%); no patient in group 2 had perioperative complications. Mean hospital stay was 1.3 days for group 1 (SD 0.85; 1-4) and 2.9 days for group 2 (SD 0.31; 2-3). Three patients in group 1 (23%) and 2 in group 2 (20%) presented postoperative complications. Mean cost per process was 4740 EUR for group 1 and 7099 EUR for group 2. CONCLUSIONS: SUI correction by tension free tapes as day surgery is a valid option which saves a substantial amount of resources.

ABSTRACT

OBJETIVO: Analizar las indicaciones actuales del auto-trasplante renal (ATR), así como los aspectostécnicos, complicaciones y seguimiento a largo plazo de esta técnica. MÉTODOS: Desde 1990 a 2005 se han llevado a cabo un ATR en 10 pacientes, 7 adultos y 3 niños. La indicación fue por patología del pedículo vascular en 8 casos y por lesión ureteral en 2. En los 8 casos con patología vascular, ésta se distribuyó en: estenosis por ateromatosis (4), estenosis por displasia (2), estenosispor enfermedad de Takayasu (1) y aneurisma de arteria renal (1). Los dos pacientes con lesión ureteral correspondieron a una estenosis ureteral secundaria a Enfermedad de Crohn inicialmente resuelta mediante stent ureteral, que posteriormente se obstruyó por incrustación litiásica; y una por avulsión ureteral yatrógena post-ureteroscopia. En los 8 casos en que fue necesaria la reconstrucción vascular los injertos vasculares utilizados fueron: en 7 pacientes arteria hipogástrica y en 1 vena sáfena. En 5 casos fue necesario llevar a cabo una reimplantación ureteral tras la cirugía de banco, mientras que en otros 5 la reconstrucción vascular se realizó sin desinsercción ureteral. En todos los casos los injertos fueron perfundidos con Ringer Lactato o Wisconsina 4ºC y protegidos con isquemia fría de superficie. Los tiempos de isquemia oscilaron entre 42 y 89 min. RESULTADOS: Nueve (90%) riñones fueron funcionantes tras el ATR teniendo 8 de ellos función inmediata tras la intervención y uno de ellos función retardada tras un período de necrosis tubular de 6 días de duración. El riñón nunca funcionante correspondió al de la estenosis arterial secundaria a enfermedad de Takayasu. La causa de la pérdida del injerto fue la trombosis de la vena renal. La mortalidad postoperatoria de la serie fue nula (0%). Con un tiempo medio de seguimiento de 72+-13 meses la creatinina media es de 1,6+-0,4 mg/dl (1,1-2,4) y el 70% (7/10) de los pacientes están normotensos sin necesidad de medicación hipotensora. CONCLUSIONES: El ATR, con o sin reconstrucción vascular extracorpórea, es una técnica compleja que tiene indicaciones excepcionales en la actualidad, pero que permite rescatar unidades renales afectas de patología vascular no subsidiarias de angioplastia o revascularización in situ. Así mismo, es una alternativa válida a la interposición de ileon en casos de lesión ureteral extensa (AU)

ABSTRACT

Objetivo: Las técnicas de inserción de mallas periuretrales libres de tensión para el tratamiento de la incontinencia urinaria de esfuerzo (IUE) son sencillas y permiten la realización del procedimiento en régimen cirugía mayor ambulatoria (CMA). El objetivo del trabajo es realizar un estudio de impacto presupuestario comparando la TVT en régimen de CMA con la TVT-O en régimen de cirugía con ingreso. Métodos: Análisis retrospectivo de 23 pacientes intervenidas por IUE entre octubre del 2004 y octubre del 2005. Trece (13) pacientes fueron tratadas en el servicio de urología (TVT - CMA) (Grupo 1) y 10 en el servicio de ginecología (TVT-O con ingreso)(Grupo 2). Se llevó a cabo un análisis de costes mediante la construcción de un modelo de Marcov, que incorpora la secuencia temporal y lógica del tratamiento, incluyendo los acontecimientos adversos y los resultados. Las variables consideradas para el cálculo de coste global incluyeron el numero de visitas y pruebas complementarias preoperatorios; los tiempos de quirófano, el coste del implante, las estancias, y las visitas imprevistas en consultas, urgencias y/o reingresos durante el primer mes posterior a la cirugía. El análisis estadístico se realizó con el programa G-Stat. Las comparaciones entre variables cuantitativas se realizaron mediante la prueba de la t de student. Resultados: Once de las 13 pacientes (84.6%) del grupo 1 completaron satisfactoriamente el protocolo de CMA. El tiempo medio de quirófano fue de 61.7 minutos (DE 16.2; Rango 35-100) y 61.6 minutos (DE 8.3; Rango 50-73) (p = 0.97) para los grupos 1 y 2, respectivamente. En el grupo 1 aparecieron complicaciones perioperatorias en 2 casos (15,4%); ninguna paciente del grupo 2 presentó complicaciones. La estancia media en el grupo 1 fue de 1.3 días (DE 0.85; rango 1-4) y en el grupo 2 2.9 días (DE 0.31; rango 2-3) . 3 pacientes presentaron complicaciones postoperatorias en el grupo 1 (23%) y 2 en grupo 2 (20%). El coste medio por proceso fue de 4740 euros para el grupo 1 y 7099 en el grupo 2. Conclusiones: La corrección de la IUE mediante mallas libres de tensión en régimen de CMA es una opción viable que supone un ahorro substancial de recursos (AU)

ABSTRACT

OBJETIVO: Revisar las indicaciones y complicaciones del uso de los catéteres endourológicos asociado al tratamiento de la litiasis urinaria. Establecer la elección de los mismos en base a sus características físicas, hidrodinámicas y de biocompatibilidad. MÉTODOS: Se resumen los datos de los estudios experimentales y clínicos obtenidos por los autores en sus estudios, llevando a cabo también una revisión de los datos existentes en la literautra. RESULTADOS: Los catéteres de poliuretano, C-Flex y Percuflex son los de mayor fuerza de retención, mientras que los de silicona, Urosoft y Wiruthan son los de menor. La fuerza tensil del poliuretano y los copolimeros es mayor que la de la silicona. El coeficiente de fricción, que es variable dentro de un mismo material, condiciona la facilidad de inserción del catéter. El número y diámetro de los orificios laterales del catéter es el elemento esencial en el comportamiento hidrodinámico del mismo. La silicona es el material más biocompatible seguida del Urosoft. Los poliuretanos y el C-Flex inducen importante hiperplasia urotelial y edema de lámina propia. CONCLUSIONES: La elección de un catéter endourológico ha de ser individualizada en base a la indicación clínica. En la prevención de la obstrucción por calle litiásica post-litofragmentación se ha de seleccionar un catéter de flujo extraluminal alto y fuerza de retención elevada que favorezca el descenso de los fragmentos, evitando la migración del catéter (AU)
