Context: Treatment of Stage I Bladder Cancer / Treatment Options for Stage I Bladder Cancer
Staging a bladder cancer via TUR is based on the extent of invasion. To assess whether cancer has invaded the muscle, muscularis propria must be present in the resected tissue. While a repeat TUR is generally considered mandatory for T1 and high-grade noninvasive bladder cancers if no muscularis propria is present in the resected tissue from the first TUR, many experts recommend that a second TUR be routinely performed within 2 to 6 weeks of the first TUR to confirm staging and achieve a more complete resection. The rationale for this derives from numerous findings, including:
The risk of local recurrence after TUR is high.
Residual cancer is often found when a repeat TUR is performed.
More-advanced–stage cancer is sometimes found with repeat TUR.
Patients undergoing radical cystectomy for nonmuscle-invasive bladder cancer are often found to have T2 or greater disease when the cystectomy specimen is examined.
A substantial number of patients with high-grade nonmuscle-invasive bladder cancer subsequently die of their disease.
Evidence (routine repeat TUR):
A review of more than 2,400 patients from over 60 different institutions reported a 3-month recurrence rate of roughly 14% to 20% after TUR, while a literature review reported that up to 10% of patients who underwent a second TUR for Ta to T1 cancer were upstaged to T2.[9] The likelihood of being upstaged to T2 is much higher when no muscularis propria is present in the initial TUR tissue.[10]
One retrospective series of 38 patients with Tis or Ta disease who underwent a second TUR found that nine patients (24%) had lamina propria invasion (T1) and three patients (8%) had muscle invasion (T2).[11]

A subsequent study from a different institution reported that among 214 patients with Ta to T1 cancers who underwent a second TUR, 27% of Ta and 37% of T1 patients had residual cancer detected.[12]

A review of other published papers reported that residual tumor was present in 27% to 62% of cases, and muscle-invasive disease was discovered in 1% to 10% of case series with at least 50 patients.[10]
Source links and citations
Repeat TUR has not been shown to reduce relapse rates or prolong survival, but there is a clear rationale for seeking accurate staging information on which to base treatment decisions. Such information may change the definitive management options for patients and identify patients who are more likely to benefit from more aggressive treatment.
