Suprapubic cystostomy catheterization in open-heart surgery.

Monitoring of the urinary output is mandatory during open-heart surgery and in the immediate postoperative period. During 1980-81 we noticed an alarming rise in the number of post-catheterization urethral strictures affecting men who had undergone open-heart surgery. To avoid this serious complication, we switched from conventional urethral catheterization to suprapubic cystostomy for these patients. The first 93 cases with suprapubic drainage have now been analysed as regards the advantages and complications of this technique. The advantages were clear: The patients were satisfied with the method and no urethral strictures developed. The only side effect was haematuria, which in 9 cases led to occlusion of the catheter and required extraneous maneouvres. Suprapubic cystostomy thus seems to be a good alternative to conventional urethral catheterization in open-heart surgery. The possible causes of the urethral complications in this particular group of patients also are discussed.
