Abstract

Objectives: The cutaneous ureterostomy is the simplest urinary diversion method; however, it often causes stomal stenosis, requiring sustained catheterization with regular catheter exchange. In an attempt to prevent stomal stenosis after surgery, the fascia (S-U fascia) between the spermatic cords and the ureters, which is usually cut off, was preserved. The remaining capillaries in the fascia could supply blood to the ureters, which is one of the most important factors for ureter patency. Methods: In 58 patients (93 renal units) undergoing cutaneous ureterostomy, 36 patients (66 renal units) were treated by the modified technique. Results: The surgeries carried out with the modified technique were significantly different in the type of operation, the side relationship, and the catheter-free rate using the univariate analysis by means of the predicted tests, in comparison with 22 patients (27 renal units) that were treated with the conventional technique. Multivariate analysis for the type of operation determined that of the side relationship and the method, only the latter was a significant factor. The modified method allowed ∼90% of the patients to have a catheter-free life; otherwise 74% of the patients had stomal stenosis, followed by catheterization. Conclusion: The presented cutaneous ureterostomy technique to preserve the fascia is useful not only to prevent stomal stenosis and maintaining good quality of life without catheterization, but also to apply to other types of ureter surgery.
