Megameatus intact prepuce (MIP) is an unusual variant of hypospadias and comprised 3 percent of all hypospadias. Embryologically, maldevelopment of glandular epithelial infolding would appear to be the abnormal process responsible for MIP formation. We have performed the pyramid procedures in 3 patients seen with the MIP variant during 14 months and achieved good results. The pyramid procedure optimizes a safe and simple dissection of the megameatus-urethra, and allows for subsequent reduction and caliber of both with excellent functional and cosmetic results.

We reviewed the result of one-stage hypospadias repair of 32 cases, from Jan. 1989 to Dec. 1994, according to the site of urethral opening after release of chordee. The following results were obtained. 1. The posterior hypospadias (posterior penile, penoscrotal) was 18 cases and the anterior & middle hypospadias was 16 cases. 2. Success rate of posterior hypospadias repair was 9/18(50%) and that of anterior & middle hypospadias was 9/16(56.3%), it was not different statistically (P<0.05). 3. Complication rate of posterior hypospadias repair was 9/18 (50%) and of anterior & middle hypospadias was 7/16(43,5%), it was not different statistically (P<0.05) and complications were managed by simple procedure and require no further treatment. In condition, one stage repair of hypospadias could be applicable in most cases of hypospadias. The complication and morbidity were minimal.

A review was presented in 4 cases of one-stage Duckett's method for hypospadia which was experienced in our hospital. Of 4 cases, 1 case was successed by only Duckett's method and 3 cases needed 2nd operation. But, it was emphasized that the island flap one-stage hypospadias technique was worth trying and the addition of skill in technique would satisfactory results.

Megameatus intact prepuce variant is an unusual anterior hypospadias variant.This type of hypospadias is the combination of widely splayed coronal or subcoronal megameatus, deep glandular groove, and an intact prepuce.There is no chordee with this variant. The over all incidence of the MIP variant is approximately 3 percent (6 percent of anterior hypospadias). Intact prepuce can lead to possible late recognition of this malformation. MIP variant is one of the most technically challenging types of hypospadias to repair. So, recognition is important because of uncommon combination and technical challenge of this malformation. I report a very rare case of Megameatus Intact Prepuce hypospadias variant and reviewed .the relevant literatures.

There is no one good method for all hypospadias repairs. A technique must be adapted for each individual patient: therefore, the urologist ought to be proficient in performing a number of procedures in order to be prepared for all possible eventualities. And one-stage operations are preferable whenever they are judged to have a reasonable chance for success. Herein we report hypospadias repairs on 17 patients between August, 1985 and July, 1986. In 7cases of two stage operations such as Belt-Fugua and Thiersch-Duplay tube with glans channel, the success rate was 57%. In 10 cases of one stage operations such as Mathieu, King and Duckett, the success rate was 50%."

Analysing cytogenetic charateristics of 24 patients with hypospadias in Vietnam National Hospital of Pediatrics from January to December 1998, comparing with clinical and surgical diagnosis. 3 children were found with chromosomal aberrations. All these children had peripheral hypospadias , 2 out of 3 children had bilateral undescend testes, 1 child had unilateral undescend testes. Chromosomal test found that: 1 child had mosaicism 46,XX(90%)/47XXY(10%); Barr bodies 8%, 2 children had 46,XX males, 1 out of these 2 children had plastic surgery for male urethra. The results of Barr bodies tests were corresponded to karyotypes. If karyotype is 46,XY, Barr bodies tests are negative; if karyotype is 46,XX, Barr bodies tests are positive

From December 1995 to June 2000, 182 patients suffering from hypospadias were operated by using a longitudinal pedicular munocutaneous flap of the penile dorsal side including 68 patients with only procedure. Of 182 patients, 161 patients were penile form, 20 children were scrotal form and 1 child was perineal form. Postoperative complications included urethral fistular in 15 patients (8.2%), urethral stenosis in 2 patients (1.6%), glandular dehiscence in 4 patients (2.2%), and meatal stenosis in 5 children (2.7%). The results in this study showed that the method has a very good result with a very low incidence of postoperative urethral fistular.
