Performance evaluation of orthotopic bladder reconstruction with ileocecum-appendix evaluated by imaging urodynamics / 中华老年医学杂志

ABSTRACT

Objective To evaluate the effect of the urinary reservoir constructed with ileocecum-appendix in the elderly with bladder cancer. Methods From March 2002 to June 2008, 12 cases were treated using ileocecum-appendix as the reservoir after radical cystectomy. They all received the imaging urodynamics examination and were followed up for 1 year. Results The 11 of 12 patients had urinary continence completely. Only 1 case had incontinence and 3 cases had incontinentia urinae at night. Times of uresis were 8-10/day and 3-5/night within 3 months after surgery, and 4-6/day and 0-2/night 6 months after surgery. The urinary output was 150-350 ml/time. Urodynamics showed that mean urinary flow rate was 10.5 ml/s, mean initial bladder pressure was 27 cm H2O, the maximum filling pressure was 35 cm H2O. The average reservoir capacity was 152 ml and 420 ml, respectively. The out let pressure of posterior urethra was 52 cm H2O. The volume of residual urine was 0-65 ml. No evidence of ureteral reflux occurred, no hyperchloremic acidosis was observed. Conclusions Orthotopic bladder reconstruction is considered as an ideal form of urinary diversion characterized by low pressure, larger capacity and continence.
