RESUMO
Objective To evaluate the diagnosis and micro-invasive treatment of ureteral obstruction after complete cystectomy. Methods All the 12 patients (primary diseases:10 cases of bladder tumor,1 of small bladder of tuberculosis,1 of radiocystitis;post-operative ureteral obstruction:9 cases of anastomotic stenosis,3 of supra-anastomotic obstruction) underwent MRI and experienced nephroscopic monitoring for diagnosis.Eleven patients underwent surgical treatment.Of them,6 cases received ureter nickel-titanium alloy trestle;4 cases (6 sides),ureter trestle,and 1,ureterocystostomy. Results All the 12 cases were correctly diagnosed.Of them 11 were followed up for 3 months to 5 years.IVU showed normal renal function and complete resolution of hydronephrosis of the diseased kidneys in 9 cases and relief of hydronephrosis in 2.Cr and BUN were normal in all the cases.Only one case of bladder cancer died of lung metastasis. Conclusions Pelviureteroradiography under MRI or nephroscopic monitoring is the most valuable method of examination for ureteral obstruction after complete cystectomy.Surgical ureter trestle and nickel-titanium alloy ureter trestle are simple,micro-invasive and effective for paitens with such post-operative obstruction.
