Diuresis-Renography with method F+10sp, a gravity-assisted approach for functional evaluation of uretero-ileal anastomosis.

Conclusions: In patients with urinary diversion, the urine drainage is strongly influenced by patient position (supine or seated). The DR with method F+10sp exploiting gravity, better evaluates the gravity-dependent urine drainage, discriminating obstruction from simple urinary dilation. Thanks to a reduced dose of Furosemide (20 mg) and a better timing, this approach avoids the side effects typical of other methods (bladder filling, disruption because voiding, or diuretic-related-hypotension). The semi-quantitave indexes Tmax, Diuretic T1/2 and Ratio 20min/peak calculated in seated position may allow a more realistic and objective evaluation of urinary drainage, avoiding equivocal or false positive responses. In light of the high rate of early stenosis (<6 months) of the uretero-ileal anastomosis considering the functional limits of traditional radiological tests, it could be useful to use this approach during first months after surgery.
