RESUMO

Kidney transplant is the established treatment for patients with chronic kidney disease but is associated with complications due to the complexity of the procedure. Calyceal fistulas are rare urological complications in transplants caused by arterial occlusion with segmental infarction of the graft. Treatment is based on the extension of the affected area and the clinical status of the patient. For extensive infarctions treated surgically, a total nephrectomy of the transplanted kidney is generally performed. We present a case of a transplanted kidney with polar necrosis and calyceal fistula treated with partial nephrectomy of the affected area, maintaining the graft and preserving kidney function.

RESUMO

INTRODUCTION: Colorenal fistula is rare in the pediatric population. It may occur at any segment involved by ischemia, chronic inflammation, or necrosis. It is typically associated with a preliminary renal lesion that may arise as a result of interventional procedures, inflammatory conditions, colon tumor, and xanthogranulomatous pyelonephritis, among others. CASE REPORT: 15-year-old female patient diagnosed with acute lymphoblastic leukemia admitted at our institution for baseline condition management. During her stay, she experienced gastrointestinal and urinary infectious events. In the assessment and management of those, a left colorenal fistula was found. Surgical treatment was decided upon. DISCUSSION: Colorenal fistula typically occurs secondary to renal inflammation or infection. Clinical signs are highly variable, and treatment is surgical, with the fistulous tract being resected in all cases.

INTRODUCCION: Las fístulas colorrenales son infrecuentes en la población pediátrica. Pueden desarrollarse en cualquier segmento afectado por isquemia, inflamación crónica o necrosis. Suelen estar asociadas a una lesión primitiva en el riñón que puede producirse por procedimientos intervencionistas, enfermedades inflamatorias, tumorales del colon, pielonefritis xantogranulomatosa, entre otras. CASO CLINICO: Paciente femenina de 15 años, con diagnóstico de leucemia linfoide aguda, ingresa a la institución para recibir manejo de su enfermedad de base. Durante su evolución, desarrolla eventos infecciosos (gastrointestinales y urinarios), y en evaluación y manejo de estos se documenta fístula colorrenal izquierda, motivo por el cual se da un enfoque de tratamiento quirúrgico. COMENTARIOS: La fístula renocólica generalmente se presenta secundaria a procesos inflamatorios o infecciosos renales; su presentación clínica es muy variada, y el tratamiento es quirúrgico, incluyendo siempre la resección del trayecto fistuloso.

RESUMO

INTRODUCTION: Transposition of the gracilis has been used in a large number of reconstructive procedures. Its advantage is its proximity to these defects and a good blood supply. Traditionally, the gracilis mobilization is performed by open surgery with one or more incisions. We describe our initial experience with the video-endoscopic mobilization of gracilis. METHOD: We described a retrospective review of all patients who underwent gracilis muscle mobilization for treatment of rectourethral fistula, performed by video-endoscopy, between March 2013 and September 2017, for treatment of rectourethral fistula. Also, our surgical technique is described in detail. RESULTS: Three patients, with a mean age of 66.6 years, underwent the procedures. The mean time for mobilization of the gracilis was 107 min (range 60-145). There was no case of donor area infection, no change in the sensitivity of the medial aspect of the thigh or chronic pain. Conversion to open surgery was not necessary in any case. The hospital discharge occurred in average after 4 days. The bladder catheter was removed after 4 weeks after cystography was performed without evidence of leakage. One patient had a recurrence of the fistula. DISCUSSION: The gracilis is an excellent choice of tissue to be interposed in reconstructive procedures of the perineal region, especially in the treatment of rectourinary fistulas. However, endoscopic harvest of the gracilis muscle has not yet found its way into everyday practice. The results in the treatment of rectourinary fistulas are excellent, with a success rate of 87.7%. Our rate of 67% is below, probably due to the small number of cases. In open surgery, complications are uncommon; however, approximately half of the patients expressed concern about the painful scar, which can be reduced by minimally invasive access. CONCLUSION: Video-endoscopic mobilization of gracilis muscle for the treatment of rectourethral fistula is feasible and safe. Studies comparing this technique with the conventional mobilization are required.

RESUMO

ABSTRACT Purpose: To evaluate efficacy of urorectal fistula (URF) repair using different approaches and the clinical factor determinant of success, and also the morbidity associated to the procedure and health-related quality of life (HRQoL) in male survivors of pelvic malignancies. Material and Methods: Retrospective evaluation of 39 patients with URF primarily intervened in three institutions using different surgical approaches. Success was defined as effective fistula closure. Variables evaluated included demographics, previous treatments, surgical approach, ancillary surgeries, complications and HRQoL by using a standardized non-validated specific questionnaire. Median follow-up from surgery to interview was 55 months (interquartile range 49, range 4-112). Factors determinant of success were investigated using logistic regression. Safety of the procedure was evaluated by Clavien-Dindo scale. Deterioration of continence and erectile function and other HRQoL issues were evaluated. Results: Prostate cancer treatment was the predominant etiology. The success rate for fistula repair was 89.5%. The surgical approach was not related to failed repair (p=0.35) or complications (p=0.29). Factors associated with failure were complications (p=0.025), radiotherapy (p=0.03), fistula location (p=0.04) and fistula size (p=0.007). Multivariate analysis revealed fistula size was the only independent determinant of failure (OR 6.904, 1.01-47.75). Complications occurred in 46.2% and severe complications in 12.8%. The mortality related to the procedure was 2.6%. Urinary incontinence was present before repair in 26.3% and erectile dysfunction in 89.5%. Fistula repair caused de novo urinary incontinence in 7.9% and deterioration of erectile status in 44.7%. Globally 79% were satisfied after repair and only 7.9% rated HRQoL as unhappy. Trans-sphincteric approach was related to less deterioration of erectile function (p=0.003), and higher perceived satisfaction in QoL (p=0.04). Conclusions: The surgical approach elected to correct URF is not determinant of success nor of complications. Fistula size appears as independent determinant for failure. Transsphincteric approach could be advantageous over other procedures regarding HRQoL issues.

RESUMO

Introducción: La eliminación de orina que con tiene grandes cantidades de material quiloso y adquiere un aspecto lechoso se conoce con el nombre de quiluria. Salvo en las regiones donde es endémica, la filariasis linfática, principal etiología, se considera en general como un trastorno raro. Objetivo: Describir un caso de quiluria asociada al embarazo. Caso clínico: Paciente femenina de 32 años de edad, con múltiples ingresos en el Servicio de Nefrología del Hospital Celia Sánchez Manduley desde el año 2007 por presentar orinas de color blanquecino, cuadro que comenzó con el primer embarazo, el síntoma desapareció y luego reapareció con el segundo embarazo, primero de forma intermitente y después, adquirió carácter permanente, con hematuria, proteinuria, edemas y otras alteraciones clínicas y bioquímicas. Conclusiones: La nefrectomía está indicada en la quiluria, cuando pone en riesgo la vida del paciente o afecta su calidad de vida, si no se tienen otras alternativas terapéuticas(AU)

Introduction: The elimination of urine containing large amounts of chyllous material and acquiring a milky appearance is known as quiluria. Except in regions where it is endemic, lymphatic filariasis, the main etiology, is generally considered to be a rare disorder. Objective: To describe a case of chyluria associated with pregnancy. Clinical case: 32-year-old female patient with multiple admissions to the nephrology service at Hospital Celia Sánchez Manduley since 2007 for presenting whitish urine, a clinical picture that began with the first pregnancy. The symptom disappeared, then reappeared with the second pregnancy, first intermittently and then became permanent with hematuria, proteinuria, edema and other clinical and biochemical alterations. Conclusions: Nephrectomy is indicated in chyluria when it puts the patient's life at risk and affects the quality of life, if there are no other therapeutic alternatives(AU)
