Rabbit urethral regeneration using small intestinal submucosa onlay grafts.

Objectives: To determine if small intestinal submucosa (SIS) can evoke urethral regeneration.

Methods: Twenty male white New Zealand rabbits were assigned to one of three experimental groups. Group 1 (n = 4) underwent simple urethrotomy and closure.

The impact of pre-donated autologous blood and intra-operative isovolaemic haemodilution on the outcome of transfusion in patients undergoing radical retropubic prostatectomy.

Objective: To assess the impact of pre-donated autologous blood and intra-operative isovolaemic haemodilution on the outcome of transfusions in patients undergoing radical retropubic prostatectomy.

Patients And Methods: The charts and transfusion records of 192 consecutive patients undergoing radical retropubic prostatectomy were reviewed retrospectively.

Results: Of 192 patients, 14% required homologous transfusions, the rate of which varied significantly depending upon blood availability (autologous, haemodilution or homologous) (P < 0.
