[Orthotopic detenia cecal-ascending colon urinary reservoir: report of 18 cases].

OBJECTIVE

To improve the technique of detenia cecal-ascending colon continent urinary reservoir for farther improving the life quality of the patient.

METHODS

Orthotopic detenia cecal-ascending colon urinary reservoir was carried out by complete resection of all the tenia and multiple transverse incision of colonic circular muscular layer for 18 patients with bladder cancer underwent radical cystectomy.

RESULTS

The patients have been followed up for 6-20 months. All were completely continent during the day and 13 patients got complete continence at the night. Only 3 patients had nocturnal incontinence. The capacity of the urine reservoir was 410-520 ml. The maximum intrareservoir pressure was 39-60 cmH2O, while the post-micturition residual volume was 15-46 ml and the maximum flow rate was 12-28 ml/per second. No evidence of ureter reflux and ureteral obstruction was observed and serum electrolytes were normal in all patients.

CONCLUSIONS

Orthotopic detenia cecal-ascending colon urinary reservoir shows good clinical and functional results, and the simple technique, exerts low pressure in the reservoir and produces minimal complications.
