Hypospadias repair without a bladder drainage catheter.

We report on 44 consecutive patients who underwent 1-stage hypospadias repair based on a urethral splent (silicone pleated stent). The severity of hypospadias ranged from subcoronal in 12 cases and distal in 23 to midshaft in 4 and penoscrotal in 5. In the first 15 patients of this series the splent was used with a suprapubic tube. All patients were able to void within the first 36 hours postoperatively. The next 29 patients underwent repairs without the use of a bladder catheter, including 15 who had outpatient procedures. None of the 44 patients has required subsequent catheterization or hospitalization. There have been 2 fistulas in this series. The urethral splent permits normal voiding through and drainage of the neourethra in a variety of hypospadias repairs. The splent expands and contracts with the degree of edema and permits catheterization should this be necessary. The advantages of hypospadias repair without bladder drainage, such as short hospital stay, total ambulation, and decreased potential for infection and bladder spasm, can be realized with the use of a urethral splent.
