Objective: To improve the ileum bladder abdominal wall fistula and evaluate its clinical effect. Methods: From January 2010 to January 2020

the general data

perioperative condition and postoperative complications of the patients who underwent the modified ileum bladder abdominal wall fistula (the study group) and Bricker operations (the control group) were analyzed retrospectively. Results: There were 35 cases in the study group and 48 cases in the control group. There was no significant difference in the general clinical data between two groups (P>0.05). The average operation time in the study group was (76.3±5.5) min

which was significantly shorter than that in the control group of (111.0±5.4) min (P<0.05). However

there was no statistical difference in bleeding

hospitalization time

drainage time

ureteral stent removal time and postoperative TNM staging between two groups (P>0.05). The incidence of total renal function abnormality

dermatitis around the stoma and scar in the study group were significantly lower than that in the control group (P<0.05)

but leakage of urine

replacement of bladder stones

necrosis or stenosis of ileostomy between two groups had significant differences (P>0.05). The incidence of adhesive ileus and hydronephrosis in the study group was 0%

which was significantly lower than that in the traditional ileostomy group (12.7%

15.9%) (P<0.05). Conclusion: The improved ileum bladder abdominal wall fistula has more reliable clinical effect and shorter operation time

and can avoid the complications of Bricker’s operation and traditional ileum bladder abdominal wall fistula

which is expected to become a more ideal urinary diversion operation.
