Abstract: Objective: To investigate the surgical technique and clinical effectiveness of Posterior Laparoscopic surgery combined with hypogastrium oblique incision for ureter cancer. Methods: All of the patients remained prostrate after general anaesthesia was administered and a hypogastrium oblique incision was employed to remove an inferior segment of the ureter including a 1 cm circle of bladder surrounding the ureter orifice. Then the patient was moved to a reclining position on the uninjured side to perform the posterior laparoscopic surgery. Put the sample into the self- command sample bag, then take out the renal by the incision. Results: Operating time was 150 to 180 minutes (median 140 mins)and blood loss was 10 to 60m1 (median 20 m1). Food intake was started on hospital day 1- 3 (median 1.5 days) and patient discharge from the hospital was 7- 10 days after surgery. Histopathological examination of the specimens revealed all of the patients had transitional cell carcinoma grade Ⅰ~Ⅱ. Follow up continued for 1- 19 months (median 8 months) after surgery without recurrence or metastasis. Conclusion: Posterior Laparoscopic surgery combined with hypogastrium oblique incision for ureter cancer uses a small incision, incurs less blood loss, and allows for a more rapid recovery, suggesting it is a safe and effective method for treating patients with ureter cancer.
