Transurethral resection and partial cystectomy for invasive bladder cancer.

Bladder-preserving modalities for patients with invasive bladder cancer have become increasingly popular in recent years. Surgical-only approaches, such as transurethral resection (TUR) or partial cystectomy, are unique among a variety of bladder-preserving modalities, most of which involve combination with radiation and chemotherapy. TUR and partial cystectomy remain incompletely evaluated due to relatively small series in the literature and the lack of standardized selection criteria. The outcome as measured by long-term bladder preservation and overall survival is not dissimilar to concurrent radical cystectomy series, possibly because of positive selection of patients.
