Patients with lower neuron lesion neurogenic bladder, with normal upper urinary tracts, poor closing pressure of the urethra, and absence of vesicoureteral reflux can be considered candidates for the insertion of the silicone-gel (Kaufman) prosthesis. Our results in 10 cases indicated that there is a place for passive urethral compression in the treatment of neurogenic bladder after a careful selection of patients and using objective methods to regulate the amount of urethral compression. The use of a combined operation (silicone-gel prosthesis and a Small-Carrion prosthesis) in some of the cases is also presented.
