ABSTRACT
This study was performed on 60 patients with invasive bladder cancer divided into 2 groups: Group A comprised 29 patients who underwent radical cystectomy and reconstructed with neoileal bladder and group B included 31 patients who were reconstructed by ileocecal bladder substitutions after radical cy stectomy. Postoperative complications occurred in 24.1% in group A including 2 mortalities. In group B, the complication rate was 25.8%, also with 2 mortalities. Day continence was achieved in 92% and 89% in group A and B, respectively. The mean post voiding residual urine was more in group A than group B, being 90 +/- 72 cc; while it was 12 + orournal 20 cc in group B. Acidosis and hyponatremia were evident in group A. The pelvicalyceal systems were preserved in 85% of patients of group A compared with 93% in group B. The mean renal cortical thickness was less in group A than in group B. Although the cystometric capacity was more and the basal pressure was less in the neoileal bladder, this was not reflected on the degree of diurnal and nocturnal continence or back pressure on the renal units compared with the ileocecal bladder. Continence in both pouches was comparable. Moreover, the renal units were preserved better in the ileocecal bladder than in the neoileal bladder. Also, the residual urine was much more in the neoileal bladder with its potential complications of infection and stone formation. In addition, acidosis was more evident in the neoileal bladder
