Ureterocele ectópica em cão: relato de caso / Ectopic ureterocele in a dog: a case report

Relataram-se o quadro clínico, o diagnóstico, o tratamento e o acompanhamento de um cão com ureterocele ectópica e hidronefrose/hidroureter associados. Após as informações obtidas nos exames laboratoriais e de diagnóstico por imagem, o animal foi submetido à ureterocelectomia e à neoureterostomia. O cão apresentou evolução favorável após a conduta terapêutica. Apesar de pouco frequente, a ureterocele deve ser considerada como diagnóstico diferencial em animais jovens com histórico de incontinência urinária.

The clinical features, diagnosis, treatment and monitoring of a dog with an ectopic ureterocele and concomitant hydronephrosis/hydroureter were reported. After the information obtained in laboratory tests and imaging diagnosis, the animal was submitted to ureterocelectomy and neoureterostomy. The dog presented a favorable evolution after the therapy. Although infrequent, the ureterocele should be considered a differential diagnosis in young animals with history of urinary incontinence.

Pediatric ureteroceles: diagnosis, management and treatment options

The aim of the study was to evaluate clinical characteristics of ureteroceles particularly for diagnostic and treatment challenges. Data about patients treated for ureterocele in the two hospital clinics during 1996-2009 are retrospectively evaluated. There were 12 girls and 7 boys. Symptomatic urinary tract infection was found in twelve cases. Ureterocele was associated with duplex systems in eleven cases. Vesicoureteral reflux was detected in 4 patients. Bladder diverticulum complicated with ureterocele in 1 patient. Ultrasonography diagnosed ureterocele in 12 patients. Renal scarring was detected in 6 patients at the side of ureterocele. Fifteen patients showed varying degrees of hydro-ureteronephrosis. Surgical therapy included upper pole nephrectomy in 3 cases. Bladder level reconstruction was performed in 11 cases. Five patients were treated only by endoscopic incision. In the follow up period 4 patients showed long term urinary tract infections whereas 3 of them were treated endoscopically. Postoperative reflux was still present in two patients who were treated by endoscopic incision. Ureterocele diagnosis and treatment show challenges. Urinary tract infection is important marker for urinary system evaluation. Preoperative management generally depends on a combination of diagnostic methods. Endoscopic incision needs serious follow up for postoperative problems

Revision del tratamiento del ureterocele en el recien nacido y lactante / Ureterocele in the newborn: review of its treatment

Once pacientes entre 3 dias y 7 meses de edad, 8 afectos de ureterocele ectopico y 3 ureterocele ectopico correspondian a un sistema doble y uno a un sistema simple. Los 3 ureteroceles intravesicales correspondieron a sistemas simples. Del total, seis casos presentaron patologia asociada ipsi y/o contralateral. Luego de la descomprension, la unidad afecta mejoro en todos los pacientes. El control demostro la mejoriaen 2 de los casos de sistema simple, apareciendo funcion solo en un uno de los sistemas dobles previamente incluidos. La ureterohidronefrosis de los hemirriñones inferiores homo y contralateral y los reflujos preexistentes mejoraron. Aparecio reflujo en el ureterocele y hemirriñon tributario en 3 casos y en el hemirriñon inferior en uno. En dos pacientes constituye el tratamiento definitivo, los beneficios obtenidos mediante la descomprension, compensan los riesgos de un posible reflujo iatroganico
