BURCH COLPOSUSPENSION VERSUS STAMEY ENDOSCOPIC BLADDER NECK SUSPENSION - A URODYNAMIC APPRAISAL

A total of 51 consecutive female patients with genuine stress incontin ence who underwent a Burch or Stamey operation were clinically and uro dynamically evaluated preoperatively at least 8 months postoperatively . Our study group consisted of 27 women who underwent the Burch colpos uspension and 24 who had the Stamey endoscopic bladder neck suspension . The urodynamic parameters which were studied pre- and postoperativel y were the maximum flow rate (Q(max)), the residual urine (V-res), the first sensation (FS), the bladder capacity (BC), the maximum vesical pressure (P-ves max), the detrusor pressure at maximum flow (P-det/Qma x)3, the functional urethral length (L(fun)) and the maximum closure p ressure (P-clos max). The successful results of the operations were 89 % for Burch and 83% for the Stamey procedure. As for differing objecti ve urodynamic findings, the Q(max), P-clos max, V(res)and L(fun) for b oth groups were the only parameters which showed statistically signifi cant difference after surgery. The statistical comparison of the posto perative urodynamic parameters of the two operative techniques showed that L(fun), P(ves max)and P-clos max had difference in favor of Burch colposuspension. There were not statistical differences in the other studied parameters. In conclusion, according to the differentiation in the values of P-clos max, L(fun) and P-ves max, the Burch technique s eems to result in a higher increase of patient's urethral resistance.
