Abstract
Objective

To analyze and evaluate our experience in surgical treatment with the open approach of the complex ureteral stenosis after adult kidney transplantation in a tertiary level hospital in the last seven years. We have reviewed the different surgical options used.

Patients and methods

A total of 589 consecutive adult renal transplants were performed from January 2005 to December 2012. Of these, 1.1% showed some degree of symptomatic obstructive uropathy which after initial urinary diversion required open surgical approach using the ipsilateral or contralateral native urinary tract. Characteristics of the patient, clinical examinations performed and surgical technique performed as well as their results are presented.

Results

During the period under review, in 5 men and 2 women who had ureteral stenoses after renal transplant, 7 reparative surgeries were performed by open ureteropyelostomy, using ipsilateral native ureter in 6 cases and contralateral ureter in the remaining case. In one case, uretero-calicial anastomosis was performed due to severe pyelic shrinkage. There were no significant complications. Native kidney nephrectomy was not required for further complications. All the patients operated on had optimum plasma creatinine levels with resolution of previous dilatation.

Conclusions

The initial percutaneous nephrostomy followed by open surgical repair using native ureter represents a definitive, valid and optimal alternative in terms of safety and preservation of renal function.

Resumen
Objetivo

Analizar y evaluar nuestra experiencia en el tratamiento quirúrgico mediante abordaje abierto de las estenosis ureterales complejas postrasplante renal de adulto en un centro de tercer nivel en los últimos 7 años. Se revisan las diferentes alternativas quirúrgicas utilizadas.

Pacientes y métodos

Desde enero de 2005 hasta diciembre de 2012 se han realizado un total de 589 trasplantes renales de adulto consecutivos. Un 1,1% del total presentaron algún grado de uropatía obstructiva sintomática que, tras derivación urinaria inicial, requirieron de abordaje quirúrgico abierto utilizando la vía urinaria nativa ipsilateral o contralateral. Se presentan las características de los pacientes, clínica, exploraciones realizadas así como técnica quirúrgica llevada a cabo y sus resultados.

Resultados

Durante el periodo evaluado se llevaron a cabo un total de 7 cirugías reparativas en 5 varones y 2 mujeres que presentaban estenosis ureterales postrasplante renal mediante ureteropielostomía abierta utilizando uréter nativo ipsilateral en 6 casos y contralateral en el restante. En un caso de realizó anastomosis ureterocalicilar por retracción piélica extrema. No ha habido complicaciones relevantes ni se ha requerido de nefrectomía de riñón nativo por complicación posterior. La totalidad de los pacientes intervenidos presentaron cifras de creatinina plasmática óptimas con resolución de la dilatación previa.

Conclusiones

La nefrostomía percutánea inicial seguida de la corrección quirúrgica abierta mediante la utilización de uréter nativo representa una alternativa definitiva, válida y óptima en términos de seguridad y preservación de la función renal.
