['To evaluate whether prolonged postoperative stenting may reduce the risk of obstruction of the neourethra after TIP repair with deep glanular incision.', 'In a 1-year period 27 patients were operated for penile hypospadias using the TIP technique described by Snodgrass. In contrast to a previous study with 8 - 10 days of postoperative catheter drainage, the indwelling transurethral catheter was kept in place for 12 - 14 days. Deep incision of the urethral plate up to the tip of the glans is the most remarkable surgical detail, resulting in a meatus on top of the glans but in a defect on the dorsal rim of the neomeatus as well. After 3 - 6 months 22 patients were re-investigated during an outpatient visit using a scheme to describe the position of the neomeatus. Uroflowmetry was also performed. Information in three toddlers was gained by phone and 2 patients were lost to follow-up.', 'Two patients returned with significant obstruction including an urethrocutaneous fistula in one. In contrast to the good assessment by parents and compared to the early appearance after catheter removal a change in meatal position was observed in the majority of patients. Only 6 patients presented with an unchanged meatal position whereas in 16 patients the meatus lost its oval or slit-like shape as well as its position on the tip of the glans. However, despite one obstructive meatus in the coronal position 15 patients showed a sufficient size and position of the meatus underneath the tip of the glans. Uroflowmetry revealed reduced peak-flow values (mean: 8.1 ml/s) in some of the 9 patients evaluated.'] Does prolonged stenting prevent obstruction after TIP repair when the glans was deeply incised?
