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

During 1997-1999, 19 pediatric patients with ages of 3-5 (10 cases) and ages of 6-11 (9 cases) and hypospadias in the institute of pediatric operated as mustarded technique the results have shown that early complications (4) were conservative treated well. The follow up duration of 1-16 months showed good outcome.

OBJECTIVETo introduce a new procedure for repairing coronal or subcoronal hypospadias with severe chordee.

METHODSA modified technique of elongating the anterior urethra, combined with the MAGPI procedure, was used to repair the coronal or subcoronal hypospadias in 19 severe chordee patients (aged 5 to 12 years). The fibrous bands on the ventral aspect of the penis were excised to correct the chordee. If the penile curvature still remained, the corpora cavernosa dissection and elongation could be applied.

RESULTSAll of the patients were successfully treated by this procedure in one stage.

CONCLUSIONSThe modified technique of the anterior urethra elongation, combined with MAGPI procedure, might be one of the simple and effective method for repairing coronal or subcoronal hypospadias with severe chordee.

OBJECTIVETo Explore the effect of oblique preputial island flap for the treating of hypospadias.

METHODSFifty-one patients were performed one-stage urethroplasty with oblique preputial island flap to repair hypospadias.

RESULTSAll cases resulted in a good contour of the penis without any redundancy and a normal anatomic position of slit-shaped urethral meatus. The urination was perfect. Six patients occurred complications (3 cases of urinary fistula, 3 cases of meatal stenosis).

CONCLUSIONWith extensive scope of materials, reliable blood supply of skin flap, satisfactory appearance of shaping penis and few complications, one-stage urethroplasty with oblique preputial island flap is an effective method to repair hypospadias of penile type and penile-scrotal type.

OBJECTIVETo discuss the methods for urethral external meatus and glanuloplasty after correction of hypospadias.

METHODSThe V shape flap on the dorsal side of glan, combined with the bilateral glan flaps were moved to the ventral side. The flap at the ventral side of urethral external meatus was turned over. Then the urethral external meatus was repositioned to the top end of glan with the ventral defects covered by the dorsal flaps. Then the coniform glan was reconstructed.

RESULTSFrom January 2008 to December 2013, 28 cases were treated, including glandular hypospadias, postoperative retraction of external urethral meatus and meatal stenosis. 21 patients were followed up for 1 -12 months (average, 1 month) with marked improvement of glan appearance and retraction of external meatus. No meatal stenosis happened.

CONCLUSIONSPostoperative retraction of urethral external meatus and meatal stenosis can be corrected by V shape flap on the dorsal side of glan combined with the bilateral glan flaps. The flat appearance of glan can be improved. It is an ideal method for glandular hypospadias.

OBJECTIVETo increase the success rate of surgical treatment in patients with hypospadias.

METHODS220 cases of hypospadias underwent one-stage urethra plasty. After the penis was straightened, urethra plasty was performed with pediculated preputial entoplastron (Duckett's method) in 195 cases; with combination of scrotal septum and pediculated preputial entoplastron in 20 cases; with free bladder mucosa transplantation in 2 cases. The self-made dual silastic tubes with lateral mini-holes were applied to support new urethra in all the cases.

RESULTSThe patients were followed up for 1 - 8 years. 208 cases achieved successful results. There were 2 cases of urethral fistula, 6 cases of urethral stenosis at anastomosis site, 4 cases of stenosis at urethral orifice.

CONCLUSIONSThe success rate (94.5%) suggests great advantages of the self-made dual tube with lateral mini-holes to support new urethra. It can facilitate drainage and irrigation and reduce the complications such as infection, fistula and stenosis.

OBJECTIVETo explore the clinical application of the tubularized incised plate (TIP) in the surgical treatment of hypospadias.

METHODSThis study included 169 cases of hypospadias treated by TIP surgery from January 2007 to April 2009. The patients ranged in age from 1.5 to 12 years (mean 3.68 yr). The TIP technique was modified based on that described by Snodgrass, with the urethral plate longitudinally incised and a urethral stent kept in place. The patients were hospitalized for 10 days postoperatively, and followed up for an average of 2 years, ranging from 6 months to 3 years.

RESULTSComplications developed in 18 (10.6%) of the patients, most frequently meatal stenosis (9 cases, 5.3%) and urethrocutaneous fistula (8 cases, 4.7%).

CONCLUSIONThe TIP technique, as a surgical method, can be applied to most hypospadias cases. The accumulation of clinical experience and skills may help raise the success rate and reduce the complications of TIP surgery.
