Abstract
Summary
Hypospadias is one of the major problems in pediatric urology. Many operations have been adopted for the correction of this anomaly trying to achieve both functional and cosmetic integrity of penis.
To achieve an ideal repair for hypospadias, one must think of a straight penis with a patent neo-urethra free from strictures or stenosis, ending by good calibrated meatus at the tip of the glans penis to ensure proper urination, erection, ejaculation and with acceptable cosmetic results.
Of the many surgical procedures invented, the one-stage tubularized incised plate urethroplasty of Snodgrass promises a lot in the way of an ideal repair.
42 patients were included in this thesis. They were classified into 3 groups:
Group 1: 19 patients with fresh subcoronal hypospadias.
Group 2: 15 patients with fresh distal penile hypospadias.
Group 3: 8 patients with recurrent hypospadias.
Tubularized incised plate technique was applied to all groups.
In the post operative period, complications were encountered in 12% of cases and success was achieved in 88%. Complications encountered were urethro-cutaneous fistula in 4.7% of cases, meatal stenosis in 4.7% 2 patient in each group, whereas wound dehiscence was in only 2.38 %.
In group 1: Success was encountered in 89.4% of patients. The complications encountered were urethro-cutaneous fistula in 5.2% of cases as well as meatal stenosis.
In group 2: Success was encountered in 93.3% of patients. The only complication encountered was urethro-cutaneous fistula in one patient.
In group3: Success was encountered in 75% of patients. The complications encountered were meatal stenosis in 1 patient 12.5% and the same percentage in wound dehiscence.
There is a statistically significant difference between the three groups of patients as regard the incidence of complications.
Mild superficial wound infection were found in 6 cases and treated medically without residual complications.
Conclusion
The following conclusions can be drawn based upon the present work:
• TIP is a simple surgery and easily learned.
• The procedure is versatile, being applicable to
subcoronal and distal penile hypospadias both in the fresh
case and following a failed repair.
• The main complications of tubularized incised plate
urethroplasty in the present work were meatal
stenosis and urethro cutaneous fistula.
• An adequate urethral plate, at least 6-8 mm in width is
an essential prerequisite to this surgery.
• Catheterization-in fresh cases seems to be sufficient
for 5 days; as there is no better results with a longer
catheter stay.
• The incidence of complications in redo operations
(group 3) is much higher than in fresh cases.
• Supra-pubic diversion with urethral stent is much better than urethral splint only in TIPU repair of hypospadias.
