[Foley catheter versus urethral stent plus gastric tube for urine drainage following urethroplasty].

OBJECTIVE

To compare the advantages and disadvantages of the Foley catheter draining method versus the urethral stent plus gastric tube draining method for urine drainage following urethroplasty for hypospadias.

METHODS

We retrospectively analyzed the clinical data of 361 cases of hypospadias treated by urethroplasty. After operation, 91 of the cases received urine drainage with the Foley catheter (group A) and 270 with a urethral stent plus a gastric tube (group B). We compared the incidence rates of bladder irritation, fistula, urethral stricture, and urethral diverticulum between the two groups of patients.

RESULTS

No statistically significant differences were found between groups A and B in the incidences of bladder irritation (9.89% vs 10.70%, P > 0.05) and urethral diverticulum (1.09% vs 2.22%, P > 0.05). The incidence rate of fistula was markedly higher in group A than in B (20.80% vs 13.30%, P < 0.05), and so was that of urethral stricture (10.90% vs 5.55%, P < 0.05).

CONCLUSION

The urethral stent plus gastric tube draining method is more effective than the Foley catheter draining method for urine drainage following urethroplasty.
