Comparative study between two days versus seven days urethral stenting of distal hypospadias after tubularized incised plate urethroplasty
Abstract
The clinical features of hypospadias are abnormal ventral opening of the urethral meatus that may be located anywhere from the ventral aspect of glans penis to the perineum, abnormal ventral curvature of the penis (Chordee) and abnormal distribution of foreskin. The exact cause of hypospadias is unknown but it is thought to be multifactorial; genetic predisposition, inadequate hormonal stimulation, maternal-placental factors, and environmental influences. Hypospadias is classified into distal, middle and proximal. Glanular, coronal and sub coronal (distal) defects constitute about 50% of cases. The surgical treatment of hypospadias aims to correct the chordee (orthoplasty) and to create neo-urethra terminating in a slit like neomeatus at apex of the reconfigured glans restoring normal anatomy and physiology with minimal complications. At 1994, Snodgrass combined the vertical urethral plate incision to release the tension on repair with Theirsh-Duplay to propose the tabularized incised plate (TIP). The stent is important to permit the repair to be water tight, immobilize the suture line, tamponade any hemorrhage and avoid the risk of urinary retention.
