Aim : To assess the need of a second transurethral resection (TUR) in select T1G3 bladder tumor patients. Materials and Methods : All the pT1G3 bladder tumors diagnosed during the period between January 2005 and December 2008 were included. Second TUR was routinely performed in all the pT1G3 bladder tumors within 4-6 weeks. Fifty out of the 68 patients with T1G3 underwent a second TUR and were retrospectively reviewed. The primary bladder lesions were grouped as solitary papillary, multiple papillary and sessile lesions. Statistical analysis was performed using STATA version 11 (STATA Corp., Texas, USA). Results : Forty percent (n = 20) of the lesions were solitary papillary, 48% (n = 24) were multiple papillary and 12% (n = 6) were sessile lesions. All our resections had muscularis propria sampled at the end of the resection and separately sent for histopathological examination (HPE), which showed them to be tumor free. Thirty-six percent of patients had residual disease at the second resection and 4% were upstaged. Ninety-five percent of the patients (n = 19) with solitary papillary lesions did not have any residual disease and 50% (n = 12) of the multiple papillary and 83.3% (n = 5) of the sessile group had residual disease at the second TUR. Conclusions : Patients with T1G3 tumors do not represent a homogenous group. Second TUR is recommended in patients with high-grade T1 urothelial bladder carcinoma as it identifies residual disease and invasive disease. Solitary papillary lesions may be the only group where the need for the second TUR is questionable.
