title: Urethral controlled bladder substitution: a comparison between Parks S pouch and hemi-Kock pouch.
abstract: To study the effect of the configuration of ileal reservoirs on the urodynamic features, 12 S bladders and 12 Kock pouches were compared. Volume capacity and pressure characteristics were studied 6 months postoperatively. The mean capacity of the reservoirs was 500 +/- 83 ml. for the S bladder and 536 +/- 56 ml. for the Kock pouch. The amplitudes of phasic contractions at 50%, 80% and 100% capacity were similar in both groups. However, the frequency of these contractions was higher in the S bladder. The intraluminal pressure at full capacity was 31 +/- 15 cm. water for the S bladder and 39 +/- 20 cm. water for the Kock pouch. The similar urodynamic features of the S and Kock pouches indicate their ultimate expansion into reservoirs of close physical characteristics and urodynamic behavior.
