The purpose of this study was to determine the evolution of patients with unifocal lateral wall MIBC (muscle invasive bladder cancer) after cystectomy with PLND (pelvic lymph node disection) at the Urology Clinic in Tirgu Mures, and to determine tumor stage and lymph node status before and after radical cystectomy with PLND.<bold>Methods</bold>. This is a prospective study, conducted between 1 August 2012 to 31 July 2014 at Urology Clinic, with a median follow-up of 14 months (range 7-25).

Objectives. The purpose of this study was to determine the evolution of patients with unifocal lateral wall MIBC (muscle invasive bladder cancer) after cystectomy with PLND (pelvic lymph node disection) at the Urology Clinic in Tirgu Mures, and to determine tumor stage and lymph node status before and after radical cystectomy with PLND.Methods. This is a prospective study, conducted between 1 August 2012 to 31 July 2014 at Urology Clinic, with a median follow-up of 14 months (range 7-25). Inclusion criteria were: patients undergone cystectomy with PLND, and unifocal MIBC on the lateral wall of the bladder; exclusion criteria were: multiple bladder tumor, other location and clinical T stage > 3.Results. Forteen patients met the inclusion criteria, median age was 61 (range 55-72), 85.71 % were male. An increase in T3 patients was noticed from 1 to 5 cases, we noticed a decrease of N0 lymph nodes from 78.6% to 57.1% postoperatively and on the controlateral side the kappa coefficient between the preoperatively and postoperatively negative lymph nodes was 0.63.

In unifocal bladder tumors, located on the lateral wall, PLND could be an alternative with comparable results with extended PLND especially in T1 and T2 patients associated with N0 before and after surgery.
