ABSTRACT

CONTEXT: Ureteral stenosis and ureterohydronephrosis may be serious complications of aortoiliac or aortofemoral reconstructive surgery. CASE REPORT: A 62-year-old female patient presented with a six-month history of left lumbar pain. She was a smoker, and had mild chronic arterial hypertension and Takayasu arteritis. She had previously undergone three vascular interventions. In two procedures, Dacron prostheses were necessary. Excretory urography showed moderate left ureterohydronephrosis and revealed a filling defect in the ureter close to where the iliac vessels cross. This finding was compatible with ureteral stenosis, and the aortoiliac graft may have been the reason for this inflammatory process. The patient underwent laparotomy, which showed that there was a relationship between the ureteral stenosis and the vascular prosthesis. Segmental ureterectomy and end-to-end ureteroplasty with the ureter crossing over the prosthesis anteriorly were performed. There were no complications. The early and late postoperative periods were uneventful. The patient evolved well and the results from a new excretory urogram were normal. We concluded that symptomatic ureterohydronephrosis following aortoiliac graft is a real complication and needs to be quickly diagnosed and treated by urologists.


INTRODUÇÃO: Estenose ureteral e ureterohidronefrose podem ser sérias complicações da cirurgia reconstrutiva aorto-femoral ou aorto-ilíaca. RELATO DE CASO: Uma paciente de 62 anos apresentou-se referindo história de dor lombar a esquerda há seis meses. Ela era fumante, portadora de hipertensão arterial crônica leve e arterite de Takayasu. Havia sido submetida a três intervenções vasculares. Em dois procedimentos o uso de prótese de Dacron foi necessário. Uma urografia excretora revelou moderada ureterohidronefrose à esquerda e falha de enchimento no ureter próximo ao cruzamento dos vasos ilíacos. Esse achado era compatível com uma estenose ureteral e o enxerto aorto-ilíaco poderia ser a causa do processo inflamatório. A paciente foi submetida a laparotomia, que evidenciou a relação entre estenose ureteral e a prótese vascular. Ureterectomia segmentar e uretroplastia término-terminal com o ureter passando anteriormente à prótese foram realizadas. Não ocorreram complicações. Os períodos de pós-operatório precoce e tardio transcorreram sem intercorrências. A paciente evoluiu bem e uma nova urografia excretora apresenta-se normal. Concluímos que ureterohidronefrose sintomática após enxerto aorto-ilíaco é uma complicação real e precisa ser rapidamente diagnosticada e tratada pelo urologista.

ABSTRACT

CONTEXT: Ureteral fibroepithelial polyps are rare benign nonepithelial tumors, and less than 200 cases have been reported in the literature. We report on a pregnant patient with ureteral fibroepithelial polyps that were successfully treated with laparotomy. CASE REPORT: A 23-year-old pregnant woman presented with a three-month history of intermittent lumbar pain of low intensity. Abdominal ultrasonography showed that she was 13 weeks pregnant and found severe left-side ureterohydronephrosis and a heterogeneous solid mass measuring 11 x 8 x 7 centimeters in the middle portion of the ureteral topography. The investigation was complemented with magnetic resonance imaging, which confirmed the previous findings. Nephroureterectomy was performed without complications. The specimen revealed three solid tumors in the ureter, of which the largest was around eight centimeters in length. The anatomopathological report confirmed that they were fibroepithelial tumors without malignant components.


CONTEXTO: Pólipos fibroepiteliais de ureter são tumores não-epiteliais benignos raros, e menos de 200 casos foram relatados na literatura. Nós reportamos o caso de uma mulher grávida com pólipos fibroelitelial ureteral que foram tratados com sucesso por laparotomia. RELATO DE CASO: Mulher de 23 anos de idade, grávida, apresentava história de dor lombar intermitente de baixa intensidade há três meses. Ultra-sonografia abdominal revelou gravidez de 13 semanas, ureterohidronefrose grave à esquerda e massa sólida heterogênea medindo 11 x 8 x 7 cm na porção média da topografia ureteral. A investigação foi complementada com ressonância magnética, que confirmou os achados. Foi realizada nefroureterectomia sem complicações. A peça revelou três tumores sólidos em ureter, o maior apresentando aproximadamente oito centímetros longitudinalmente. O relatório anatomopatológico confirmou tumor fibroepitelial sem componentes de malignidade.
