Abstract:

Objective To compare the clinical efficacy of different urinary diversions， specifically exploring whether the flap embedding technique can improve bladder cancer patients' quality of life and reduce the incidence of related complications. Methods 63 bladder cancer patients undergoing radical cystectomy with urinary diversion， between December 2022 and December 2023， were divided into three groups： Ileal conduit group （n = 21）， flap embedding technique group （n = 21）， and traditional cutaneous ureterostomy group （n = 21）. General clinical data， surgical data， preoperative and postoperative renal function indicators， incidence of complications within 6 months postoperatively， and quality of life scores were compared among the groups. Results The operative time in the ileal conduit group was longer than that in the other two groups （P < 0.05）. The quality of life scores in the flap embedding technique group were superior to those in the traditional cutaneous ureterostomy group （P < 0.05）， but no significant difference was found compared to the ileal conduit group （P > 0.05）. In terms of postoperative complications， the incidence of intestinal obstruction in the flap embedding technique group was lower than that in the ileal conduit group （P < 0.05）， and the rate of reinsertion of a single-J stent for hydronephrosis in the flap embedding technique group was lower than that in the traditional cutaneous ureterostomy group （P < 0.05）. Postoperative serum creatinine levels in the traditional cutaneous ureterostomy group were significantly higher than preoperative levels （P < 0.05）， while no significant differences in renal function indicators were observed in the other two groups （P > 0.05）. Conclusion The flap embedding technique significantly improves patients' quality of life and reduces the incidence of postoperative complications. It is worthy of further promotion in clinical practice.
