Scintigraphic detection of urinary leakage after kidney transplantation.

Urinary leakage after kidney transplantation is a serious complication. In a retrospective study we analyzed 8 relevant cases of 14 patients with urinary leakage. In these eight patients kidney scintigraphy indicated the presence of urinary extravasation. Compared with other imaging modalities such as IV urography, cystography and ultrasound, scintigraphy seems to be an easy and safe method to detect urinary leakage. Moreover scintigraphic examination may suggest leakage, while this may not be clinically evident or suspected.
