Hypospadias repair is highly challenging especially for those severe or cripple variants.Correction via single stage or staged repair is controvercial whereas the controversies are with different content with advancement of hypospadiology.Here the authors introduce the contemporary concepts of staged repair for hypospadias.

Objective To analyze the clinical,endocrinal and genetic features of 46,XX male syndrome. Methods Retrospectively collect and analyze the clinical data of 4 cases of 46,XX male sex reversal syndrome. Results Four patients were all sociopsychologically males.Among them,2 cases had cryptorchidism,3 hypospadia and 1 severe chordee with short urethra.Neither ovary nor uterus was detected through B ultrasonography or surgical exploration.Assessment of serum sex hormone suggested hypergonadotropic hypogonadism.Genetic detection indicated 46,XX karyotype as normal female's type. Conclusions 46,XX male has nearly normal male phenotype otherwise with testes dysgenesis and most are infertile.The target of treatment is to correct the urinogenital malformation and to compensate hormone defect with androgen.

OBJECTIVE: To explore the surgical outcome of Duckett urethroplasty-urethrotomy for staged hypospadias repair. METHODS: Fifty-three patients with hypospadias were treated by 2 stages between August 2013 and September 2014. The age ranged from 10 months to 24 years and 3 months (median, 1 year and 10 months). There were 5 cases of proximal penile type, 2 cases of penoscrotal type, 36 cases of scrotal type, and 10 cases of perineal type. Urethroplasty was performed with tubed transverse preputial island flap only in 27 cases or combined with urethral plate in the other 26 cases, thus a urethrocutaneous fistula was intentionally created; stage II fistula repair was carried out at 1 year after stage I repair. RESULTS: The length of the new urethra ranged from 2 to 8 cm with an average of 3.6 cm. The patients were followed up 5-17 months with an average of 8 months after stage II repair. After stage I repair, urethral fistula was noted at other site in 3 cases, skin necrosis in 1 case, glandular stricture in 2 cases, cicatric curvature in 1 case, and position and morphology of urethral orifice not ideal in 4 cases. After stage II repair, urethral fistula was noted in 2 cases, mild urethral diverticulum in 2 cases, and stricture at temporary repair site in 1 case. HOSE score was 12-16 at 3 months after stage II repair (mean, 14.5). At 3-14 months after stage II repair, the maximum flow rate ranged from 3.9 to 22.7 mL/s with an average of 8.6 mL/s. CONCLUSIONS: Duckett urethroplasty-urethrotomy can be used as staged repair for primary treatment of hypospadias because of high safety, low complication incidence, and satisfactory appearance.

It was reported that pancreatic arteries constricted during the early phase of bile salt-induced acute pancreatitis (AP), leading to pancreatic microcirculatory disturbance. We conducted this experiment to verify whether the above-mentioned finding was true. AP was induced with intraductal injection of taurodeoxyholate. Small pancreatic artery pressure in dogs was recorded. Functional capillaries were counted and calibrated by multiplying wet weight of pancreas. Pancreatic perfusion was measured with Laser Doppler flowmeter. Pancreatic arterioles of rats dilated during the initial 20 min of AP, and pancreatic arterial pressure declined during the early phase of AP in dogs (from 104.5 +/- 4.8 mmHg to 54.6 +/- 5.6 mmHg). The hematocrit of blood from inferior vena cava was significantly lower than that of portal vein at 5 min after pancreatitis induction. The "true" pancreatic functional capillary density increased. The early pancreatic microcirculatory disturbance coincided with a marked increase of portal vein pressure (PVP) as high as 9.18 +/- 0.78 mmHg. Reduction of PVP to baseline level was followed by a marked increase of pancreatic perfusion (by 1.4-fold). Arterial dilatation, but not constriction, occurred during the early phase of bile salt-induced AP. The pancreatic microcirculatory disturbance was due to a marked rise in PVP that greatly reduced the pressure difference in the pancreatic blood vessels and increased plasma extravasation which led. to local hemoconcentration.

Objective To evaluate the role of multiple dorsal midline plication (MDMP) procedure in correction of Donnahoo type Ⅲ chordee in postpubertal patient.Methods From September 2010 to July 2013,33 postpubertal patients with Donnahoo type Ⅲ chordee (＞ 20°) were treated with MDMP procedure.The age ranged from 18 to 37 years with an average of 29 years.Primary surgery was indicated in 18 patients including type Ⅲ chordee in 11 and type Ⅲ/Ⅳ in 7,with associated hypospadias in 12.Redo surgery was warranted in 15 patients including type Ⅲ chordee in 13 and type Ⅲ/Ⅳ in 2,with associated urethral defects necessitating repair in 12.Intraoperative artificial erection was induced to confirm the degree and length of chordee.Longitudinal plication sutures,4 dots each,were applied close to the midline in a parallel fashion on each apex of curvature,to achieve satisfactory orthoplasty with 16-dot to 64-dot plication according to the chordee status,and the urethral repair indicated was achieved simultaneously.Results Satisfactory orthoplasty was achieved with 16-dot plication in 16 patients,24-dot in 10,32-dot in 6,and 64-dot in 1 patient whose penile curvature was severe and long.Followup was obtained from 35 to 69 months with an average of 46 months.Three patients lost of followup.Urethroplasty-related complications were noted in 5 patients including urethrocutaneous fistula in 2,urethral dehiscence in 1,urethral diverticulum in 1,and urethral stricture in 1.Mild cicatrical curvature (less than 15 degree) was noted in 2 patients.No postoperative priapism,erectile dysfunction,and paraesthesia was noted,nor chordee recurrence.Conclusions When applied appropriately,MDMP is an effective procedure in correction of Donnahoo type Ⅲ chordee in postpubertal patient with good and long-standing orthoplasty.

Objective:To investigate the clinical effect of surgical treatment of concealed penis based on the idea of flap transfer in the treatment of hypospadias.Methods:Retrospectively analyzed the clinical data of children with concealed penis admitted to the Urology Department of Chengdu Second People’s Hospital and Department of Pediatric Surgery at Children’s Medical Center of Sichuan Provincial People’s Hospital, from July 2017 to July 2021. The control group used the traditional surgical method and the experimental group used a modified surgical approach based on the idea of flap transfer in the treatment of hypospadias. Short-term complications such as flap ischemia, edema, and skin dehiscence were statistically analyzed in the two groups, as well as the Boemers rating of penile appearance (good, general, poor), Vancouver scar scale (VSS) (mild, moderate, severe), overall penis shape (tower, cylindrical, inverted tower) at 6 months after surgery. Count data were analyzed using the Chi-square test.Results:298 children, aged 2.5 to 13.7 years, with a mean age of 6.4 years, were enrolled in the study. 103 children were in the control group, and 195 children were in the experimental group. All enrolled patients were operated successfully in the first stage and were discharged 3-4 days after the operation, with an average recovery time of 3-4 weeks. After a follow-up of more than 6 months, in the control group, 2 cases (1.9%) of flap ischemia and 3 cases (2.9%) of skin dehiscence occurred after surgery. Two children (1.0%) in the experimental group had skin dehiscence after surgery, and the difference in the recent complication rate between the two groups was not significant [4.9%(5/103) vs. 1.0%(2/195), P>0.05]. The proportion of Boemers rated"good"in the experimental group was higher than that in the control group [93.3% (182/195) vs. 71.8% (74/103), P<0.01]. The proportion of moderate to severe scarring assessed by VSS was lower in the experimental group than in the control group [6.2% (12/195) vs. 26.2% (27/103), P<0.01]. The proportion of the overall penis shape of the penis close to the cylindrical shape of the normal penis in the experimental group was significantly higher than that in the control group [81.5% (159/195) vs. 60.2% (62/103), P<0.01]. Conclusion:Compared with the traditional surgical method, the modified surgical approach based on the idea of flap transfer in the treatment of hypospadias attaches more importance to the overall planning of the flap and the tension distribution of the fascial layer, which can be more effective to solve the problem of insufficient coverage of the concealed penile skin and reduce postoperative scar formation. Moreover, the appearance of the external genitalia is natural and closer to normal, the surgical effect is exact, and the long-term postoperative complications are lower.
