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.

Nuclear medicine images play an important role in the evaluation of urinary tract pathologies. Radionuclide imaging studies (DMSA scan, DTPA/MAG3 renography, radionuclide cistography) are reviewed, analyzing their indications.
En el diagnóstico por imágenes de las enfermedades del sistema nefrourológico, la Medicina Nuclear juega un rol importante en determinadas patologías. Se revisan los diferentes exámenes empleados en la actualidad: cintigrafía renal DMSA, renograma isotópico DTPA/MAG3, cistografía isotópica y se analizan sus principales indicaciones.
