Of 96 cases with superficial (Ta, Tis, T1) bladder tumors 72 (75%) had residual noninvasive tumor and 28 (29%) were up staged to invasive tumor. Among 54 patients with a muscle invasive tumor 12 (22%) had no residual tumor on repeat transurethral resection. Results of the second resection changed tumor treatment in 50 patients (33%).\nCONCLUSIONS: Many patients with bladder tumors have tumor present after an initial trans-urethral resection. Routine repeat resection is advised to control noninvasive tumors and to detect residual tumor invasion.","tracks":[{"project":"PubmedHPO","denotations":[{"id":"T1","span":{"begin":179,"end":193},"obj":"HP_0009725"},{"id":"T2","span":{"begin":187,"end":193},"obj":"HP_0002664"}],"attributes":[{"subj":"T1","pred":"source","obj":"PubmedHPO"},{"subj":"T2","pred":"source","obj":"PubmedHPO"}]},{"project":"PubMed_Structured_Abstracts","denotations":[{"id":"T1","span":{"begin":99,"end":205},"obj":"OBJECTIVE"},{"id":"T2","span":{"begin":229,"end":488},"obj":"METHODS"},{"id":"T3","span":{"begin":498,"end":934},"obj":"RESULTS"},{"id":"T4","span":{"begin":948,"end":1148},"obj":"CONCLUSIONS"}],"attributes":[{"subj":"T1","pred":"source","obj":"PubMed_Structured_Abstracts"},{"subj":"T2","pred":"source","obj":"PubMed_Structured_Abstracts"},{"subj":"T3","pred":"source","obj":"PubMed_Structured_Abstracts"},{"subj":"T4","pred":"source","obj":"PubMed_Structured_Abstracts"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"PubmedHPO","color":"#eca593","default":true},{"id":"PubMed_Structured_Abstracts","color":"#939aec"}]}]}}
