ABSTRACT

PURPOSE: We determined the efficacy and safety of flexible ureterorenoscopy for single intrarenal calculi and further stratified efficacy by stone burden. MATERIALS AND METHODS: CROES collected prospective data on consecutive patients with urinary stones treated with ureterorenoscopy at 114 centers worldwide for 1 year. Only patients who underwent flexible ureterorenoscopy for a solitary renal stone were included in study. Preoperative and intraoperative characteristics, and postoperative outcomes were evaluated. Relationships between stone size and the stone-free rate, operative time, complications, hospital stay and need for re-treatment were determined. RESULTS: A total of 1,210 patients with a solitary kidney stone less than 10 (52.2%), 10 to 20 (43.2%) and greater than 20 mm (4.6%) were treated with flexible ureterorenoscopy. The stone-free rate negatively correlated with stone size when adjusted for body mass index. Operative time positively correlated with stone size when adjusted for body mass index. The single session stone-free rate was 90% and 80% for stones less than 10 and less than 15 mm, respectively. Patients with stones greater than 20 mm achieved a 30% stone-free rate, more often needed re-treatment and were more often rehospitalized. There was no difference in the overall complication rate by stone size. However, patients with a stone greater than 20 mm showed a higher probability of fever after flexible ureterorenoscopy than those with a smaller stone. CONCLUSIONS: Our data indicate that flexible ureterorenoscopy for a single intrarenal stone is a safe procedure. Best results after single session flexible ureterorenoscopy were obtained for stones less than 15 mm.

ABSTRACT

OBJETIVO: La migración de cuerpos extraños que son ingeridos desde el aparato digestivo y fistulizados a vías urinarias, es poco frecuente. Nuestro objetivo es presentar un caso de un paciente con urosepsis y migración tardía de un mondadientes a vejiga. MÉTODO: Paciente masculino de 78 años quien ingresó por urosepsis, presentado ureterohidronefrosis derecha inicialmente diagnosticado como ureterolitisis obstructiva. En las imágenes de tomografía la presencia del cateter femoral confluía con la cercanías del cuerpo extraño y permitió que se confundiera con litiasis urinaria y enmascarara el proceso. Se manejó con antibioticoterapia y colocación de catéter ureteral. La ureteroscopia ulterior evidenció compresión extrínseca sobre uréter distal sin presencia de litiasis ni lesiones intravesicales. Posteriormente el paciente presenta fiebre y en los nuevos estudios radiológicos reportan un cuerpo extraño intravesical, no evidenciado en estudios previos. La uretrocistoscopia evidencia un mondadientes que se introduce en vejiga y se extrajo endoscópicamente. RESULTADOS: Retrospectivamente se interpreta que el cuerpo extraño perforó tubo digestivo, migró hacia retroperitoneo y provocó el proceso obstructivo por inflamación periureteral, y condicionó la sepsis. Posteriormente, al superar el cuadro infeccioso y a la manipulación durante la ureteroscopia, el mondadientes logró migrar hacia la luz intravesical y hacerse evidente para el diagnóstico. CONCLUSIONES: La migración de cuerpos extraños desde el tubo digestivo a la vejiga ocurre raramente. El diagnóstico se realiza mediante estudios de imagen y requiere en ocasiones un cierto nivel de sospecha(AU)


OBJECTIVE: Migration of objects into the urinary tract from the digestive tract has been described. Our objective is to report the case of a patient with urosepsis and late migration of toothpick from the gastrointestinal tract into the bladder. METHODS: A 78 y/o male patient with uro-sepsis and hydronephrosis was admitted. The initial suspected etiological cause was obstructive ureteral lithiasis. CT scan showed hydronephrosis and a possible ureteral stone. However, a femoral catheter was in place near the toothpick location, which jeopardized the detection of the foreign body. Antibiotic therapy and placement of a ureteral stent were performed. Once infection subsided, ureteroscopy was carried out showing a slight extrinsic compression of the distal ureter. The patient was readmitted with urinary infection. New imaging studies showed a foreign body in the bladder, which was not evident previously. Cystoscopy showed a toothpick penetrating the bladder and it was removed. RESULTS: Retrospectively, we interpreted that the foreign body perforated the gastrointestinal tract, migrated to the retroperitoneum and caused upper urinary tract obstruction by inflammatory reaction in the periureteral tissues. Once infection was solved, ureteral manipulation by ureteroscopy may have caused the toothpick migration into the bladder. CONCLUSIONS: Migration of foreign bodies from the gastrointestinal tract into the bladder occurs rarely. They clinically present as a complicated urinary tract infection. Imaging studies make the diagnosis, and a high level of suspicion is required(AU)

ABSTRACT

El tumor carcinoide primario de riñón es un tumor de presentación inusual, habiendo sido reportados 40 casos en la literatura. Describimos la presentación de una paciente con un tumor carcinoide primario de riñón.OBJETIVO: Aportar a la literatura un nuevo caso de tumor carcinoide renal, por lo infrecuente del mismo y su forma de presentación ajena en ocasiones a síntomas urinarios, sino más bien asociado a trastornos de otros aparatos que enmascaran el cuadro clínico, donde es más frecuente dicho tumor.MÉTODOS: Estudiar a una paciente de 80 años de edad, que es ingresada en el Servicio de Digestivo con un síndrome anémico, asociado a un cuadro clínico diarreico de una semana de evolución. Después de estudios humorales, heces fecales y de imagen se detecta masa sólida parenquimatosa renal izquierda; siendo enviada a nuestro servicio donde se le realiza nefrectomía radical. Después de 8 meses de evolución postquirúrgica su trayectoria es satisfactoria.RESULTADOS: El tumor carcinoide renal es una entidad infrecuente, que se engloba dentro de los tumores neuroendocrinos, descritos hace 100 años por Lubart, derivándose de las células de Kuchitsky, productoras de hormonas polipéptidos y aminas biógenas; siendo su frecuencia mayor en el aparato digestivo (62-67%) y respiratorio (22-27%). Normalmente estos tumores cuando se diagnostican a tiempo evolucionan favorablemente.CONCLUSIONES: El tumor carcinoide renal primario es una entidad infrecuente dentro de los tumores endocrinos. Debemos señalar que este caso su forma de presentación fue como anemia, diarreas y sangre oculta en heces fecales en la analítica(AU)


The primary carcinoid tumor of the kidney is a tumor of unusual presentation, 40 cases have been reported in the literature. We describe the presentation of a patient with a primary carcinoid tumor of the kidney.OBJETIVES: To report a new case of renal carcinoid tumor, a rare tumor sometimes presenting without uri-nary tract symptoms, but rather associated with disorders of other organs that mask the clinical picture.METHODS: To report the case of an 80 year-old patient, admitted to the Department of Gastroenterology with anaemia associated with diarrhea for one week. After blood, feces and image tests a solid mass was detected in the left renal parenquima; she was referred to our service and radical nephrectomy was performed. After 8 months of follow up her outcome is satisfactory.RESULTS: Renal carcinoid is an infrequent entity, included among neuroendocrine tumors, described 100 years ago by Lubart, derived from Kuchitsky’s cells, they produce polipeptidic hormones and biogenic amines; being more frequent in the gastrointestinal tract (62-67 %) and respiratory tract(22-27 %). Generally, these tumors have a favorable outcome when they are diagnosed in time.CONCLUSIONS: Primary renal carcinoid is an infrequent entity among endocrine tumors. We must in-dicate this case`s presentation was with anemia, diarrhea and positive occult blood in feces(AU)

ABSTRACT

La endopielotomía endoscópica alcanzó una importancia capital a partir de 1984, para el tratamiento de la obstrucción del tracto urinario superior. Primeramente por vía anterógrada y posteriormente por vía retrograda. Para simplificar estas técnicas se creó un catéter (Acucise), con el cual se realizan incisiones por vía cistoscópica, con control fluoroscópico. El mismo, incorpora un balón de tamponaje de 8mm de diámetro y un electrodo monopolar longitudinal de 100 micras de grosor. El presente trabajo es el primer reporte del uso del catéter Acucise en Venezuela. 6 pacientes con obstrucción del tracto urinario superior, (obstrucción de la unión pieloureteral), fueron tratados mediante incisiones internas con el catéter Acucise. El tiempo operatorio promedio fue de 48 min. y el período promedio de hospitazación fue de días. Se utilizó anestesia peridural en todos los casos. El seguimiento promedio fue de 12 meses. Las evaluaciones postoperatorias se realizaron en base a mejoría clínica, urogramas excretores y renogramas isotópicos. Obtuvimos resultados exitosos en el 83 por ciento de los casos (mejoría clínica y radiológica). Nuestra experiencia preliminar, aunque limitada, nos permite concluir que el tratamiento de la obstrucción del tracto urinario superior con el catéter Acucise es efectivo y seguro, pudiendo convertirse en una alternativa menos invasiva que la endopielotomía endoscópica.

ABSTRACT

Las hernias umbilicales ocupan un lugar importante dentro de la patología herniaria, con una alta incidencia tanto en niños como en adultos, afectando entre un 18 y 26// de la población general. La alta incidencia de complicaciones de las hernias umbilicales en el adulto, obliga la reparación de todas ellas. Tomando en consideración el efecto negativo que una cicatriz visible ocasiona en la población actual, consciente de su aspecto corporal, se describe una alternativa quirúrgica para el abordaje y reparación de las hernias umbilicales a través de una incisión transumbilical
