Urethral stricture following cardiovascular surgery: role of urethral ischemia. 1986

M M Elhilali, and M Hassouna, and A Abdel-Hakim, and J Teijeira

The incidence of urethral stricture has been surprisingly high following cardiovascular surgery in the last few years. We conducted a prospective study on 68 male patients undergoing cardiovascular surgery to determine the main factor(s) responsible for the development of urethral stricture. The penile-brachial pressure index was checked by strain gauge plethysmography. We found that urethral strictures developed in 15 patients (22 per cent) within an average of 3 months after cardiovascular surgery. Of these patients 13 had a penile-brachial index of 0.6 or less and complained of erectile impotence. A latex type of catheter was used in 11 and a silicone catheter in 4 of these 15 patients for urinary drainage. We conclude that urethral ischemia has an important role in the development of stricture, particularly when a latex urethral catheter is used for drainage. We recommend that a vascular penile study should be done in patients with erectile impotence undergoing an open heart operation, and that serious consideration should be given to the use of a cystocatheter diversion the night before the operation in those with a penile-brachial index less than 0.6. We strongly recommend the use of a silicone catheter in all other patients undergoing open heart surgery with hypothermia.

D010413	Penis	The external reproductive organ of males. It is composed of a mass of erectile tissue enclosed in three cylindrical fibrous compartments. Two of the three compartments, the corpus cavernosa, are placed side-by-side along the upper part of the organ. The third compartment below, the corpus spongiosum, houses the urethra.
