Effect of sucralfate on induced chemical cystitis in rabbits.

Abstract

OBJECTIVE:

To study the histological effect of locally applied sucralfate on the urinary bladder in rabbits with chemically induced cystitis.

MATERIALS AND METHODS:

Sucralfate (1 g dissolved in 10 mL saline) was instilled into the bladders of six rabbits, while four controls had no instillation. The procedure was repeated 4 days later and followed immediately by 10 mL of 2% formaldehyde infused into the bladder and retained for 10 min in all 10 rabbits. After careful flushing with saline, 10 mL sucralfate solution was again instilled in the study group and 10 mL of saline only in the control group. On day 6, the sucralfate instillation was repeated in the six treated animals. All the rabbits were then killed on day 8-9, their bladders removed and examined macroscopically and histologically.

RESULTS:

Formaldehyde instillation was quickly followed by gross haematuria in all animals. It subsided in the group treated with sucralfate, but not in the controls. Examination revealed only slight changes in the former group, but severe inflammatory lesions in the latter.

CONCLUSIONS:

Intravesically instilled sucralfate protected rabbit bladder urothelium against chemically induced cystitis. Clinical trials of intravesical sucralfate seem warranted in patients irradiated for pelvic cancer or with severe cystitis caused by cytotoxic drugs.
