The Benefits Of Estimating Surgical Methods Of Urinary Diversion By PRS In Patients With Radical Cystectomy

Objective To evaluate the value of Preoperative Risk Score(PRS) for predicting surgical methods of urinary diversion in patients with radical cystectomy.Methods To collect the clinical data of 244 cases with radical cystectomy from January 2012 to December 2014 in Department of Urinary Surgery of The First Affiliated Hospital of Chongqing Medical University,calculating the PRS by estimation of physiologic ability and surgical stress(E-PASS) and analyzing the relationship between PRS and postoperative complications in different surgical methods.Results The PRS with orthotopic neobladder was 0.342±0.209, the risk of complications increased significantly in patients of PRS≥0.23(P=0.002).The PRS with urinary diversion was 0.401±0.224,the risk of complications increased significantly in patients of PRS≥0.48(P=0.050).The PRS with cutaneous ureterostomy was0.556±0.308, the risk of complications increased significantly in patients of PRS≥0.60(P=0.009).Conclusion Patients of PRS less than 0.23 advised to choose the orthotopic neobladder, patients of PRS between 0.23 and 0.47 advised to choose urinary diversion, patients of PRS between 0.48 and 0.59 advised to choose cutaneous ureterostomy.
