Patient selection
We retrospectively assessed data from patients who underwent RC with pelvic lymphadenectomy and urinary diversion for BC recorded in the BC database of the Urooncology Association, Turkey between 2007 and 2019. All procedures were performed by 8 experienced surgeons from six different institutions. RC with pelvic lymphadenectomy and urinary diversion was performed for localized MIBC or non-muscle-invasive tumors who \soutare were at highest risk of progression. The extensiveness of pelvic lymphadenectomy and the type of urinary diversion was at surgeons’ discretion. Patients with concurrent presence of upper urinary tract carcinoma or/and the history of cancer other than bladder cancer or/and patients underwent robotic assisted RC due to low number or/and missing variables were excluded.
