Renogram in kidney transplant. Utility of delayed images with SPECT/CT in the diagnosis of urinary leak

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.
