Fluorourodynamic and clinical evaluation in males following construction of a Kock ileal-urethral reservoir.
OBJECTIVE
Since 1986, we have offered the option of lower urinary tract reconstruction with the Kock ileal-urethral reservoir in selected male patients requiring diversion. This study provides insight into the functional characteristics of the Kock ileal-urethral reservoir and its effect on continence.


METHODS
Twenty-four of the initial 225 male patients undergoing this procedure at our institution were evaluated by fluorourodynamics within 2 years of neobladder construction. Information regarding continence was also obtained by means of a patient interview and questionnaire.


RESULTS
The average resting neobladder pressure was 8.5 cm H2O (range, 0 to 18). Reservoir capacity averaged 741 cc (range, 225 to 1400). Afferent nipple failure with bilateral grade II vesicoureteral reflux was noted in 1 patient (4%). Unsatisfactory daytime continence was seen in 2 patients (8%). Unsatisfactory nighttime continence was seen in 6 patients (25%). Patient satisfaction was high with an average rating of 8.6 on a scale of 1 to 10.


CONCLUSIONS
Fluorourdynamic data demonstrate a low-pressure, high-capacity reservoir with a low incidence of reflux. The rate of continence is acceptable and patient satisfaction is excellent. The Kock ilealurethral reservoir is an excellent alternative to standard diversion for the male patient undergoing cystectomy.
