Abstract

Urinary leakage in patients with kidney transplantation is a relatively common surgical complication that requires early diagnosis and intervention. The isotopic renogram is a non-invasive and effective method to evaluate the perfusion and function of kidney transplantation, and allows us to diagnose urological complications such as urinary leakage. In these cases, it is useful to complete the study with planar images and delayed SPECT/CT to specify the diagnosis and locate the leak. We expose two cases diagnosed with urinary leak after performing a renogram with early and delayed planar images and delayed SPECT/CT a week after transplantation. In both cases, a percutaneous nephrostomy catheter was placed, as well as a double J catheter, resolving the surgical complication.

Keywords:
Kidney transplantation
Urinary leakage
Isotopic renogram
Allograft failure
Resumen

La fuga urinaria en los pacientes trasplantados renales es una complicación quirúrgica relativamente frecuente que requiere un diagnóstico e intervención precoces. El renograma isotópico es un método no invasivo y efectivo para evaluar la perfusión y función del trasplante renal, y nos permite diagnosticar complicaciones urológicas como la fuga urinaria. En estos casos es de gran utilidad completar el estudio con imágenes planares y SPECT/TC tardío para precisar el diagnóstico y localizar la fuga. Se exponen 2 casos diagnosticados de fuga urinaria tras realizar renograma con imágenes planares precoz y tardía y SPECT/TC tardío, a la semana de ser sometidos a trasplante. En ambos casos se colocó una sonda de nefrostomía percutánea, así como un catéter ureteral doble J, resolviéndose la complicación quirúrgica.
