Advances in diagnosis and treatment of ureteroenteric anastomotic stricture after urinary diversion surgery
Radical cystectomy combined with urinary diversion is the standard treatment for muscle-invasive bladder cancer.Ureteroenteric anastomotic stricture(UES)is a common postoperative complication,potentially leading to upper urinary tract obstruction,and in severe cases,deteriorating renal function and prognosis.Factors such as obesity,previous surgical history,prior history of radiotherapy or chemotherapy,robotic surgery,type of urinary diversion,and method of ureteroenteric anastomosis are associated with postoperative UES occurrence.Identifying risk factors preoperatively can aid in surgical decision-making,while meticulous intraoperative tech-niques and extensive surgical experience help mitigate UES risk.Postoperative follow-up should comprehensively assess imaging evidence and renal function to diagnose UES accurately and initiate prompt treatment.Open surgi-cal repair remains the gold standard for UES treatment due to its high success rate and durable long-term patency rate.Robotic surgical repair also demonstrates satisfactory UES control rates and safety.Endoscopic treatment can serve as a first-line option for patients with stricture ≤1 cm,yielding favorable functional outcomes and lower complication rates.
