Objective:To introduce the application of a modified scrotoplasty for children with webbed penis.Methods:Retrospective study was carried out.The treatment results of 58 children with webbed penis in Department of Urology, the Affiliated Xuzhou Children′s Hospital of Xuzhou Medical University from June 2012 to April 2018 were analyzed.A total of 26 children with webbed penis and phimosis were treated with circumcision combined with modified scrotoplasty as modified scrotoplasty group, and 32 children with webbed penis and phimosis were treated with V-Y scrotoplasty as V-Y scrotoplasty group.The curative effect of webbed penis was compared between the two groups.Results:The operation time of V-Y scrotoplasty group and modified scrotoplasty group were (26.0±2.4) min and (28.0±3.2) min; the increased penis length in the horizontal position in the two groups were (0.30±0.06) cm and (0.40±0.06) cm; the score of parents′ satisfaction were (3.80±0.47) scores and (4.70±0.56) scores, there were significant differences in the average operation time, the increased penis length in the horizontal position and the score of parents′ satisfaction between the two groups ( t=2.703, 6.061, 6.652; all P<0.05). There was no significant difference in postoperative complications between the two groups ( P>0.05). Conclusions:Circumcision combined with modified scrotoplasty is used to repair webbed penis, which results in a good postoperative appearance, high parent satisfaction and easy clinical implementation.

Objective:To compare the effectiveness of modified Sugita and modified Shiraki in the treatment of severely concealed penis in children.Methods:A retrospective study was carried out on 72 children with congenital severely concealed penis, who were treated in the Department of Urology, Xuzhou Children′s Hospital Affiliated to Xuzhou Medical University from September 2016 to June 2021.Among them, 32 cases were treated with modified Sugita (modified Sugita group) and 40 cases were treated with modified Shiraki (modified Shiraki group). There was no significant difference in the age, body mass and body mass index between the 2 groups (all P>0.05). The operation time, increased length of the exposed part of the penis after operation, score of parental satisfaction half a year after operation (obtained by using the Likert scale) and postoperative complications (classified according to the modified Clavien-Dindo classification) were compared between the 2 groups.Measurement data comparison between groups were performed by t test, counting data were analyzed by Chi- square test. Results:The operative time of the modified Sugita group and the modified Shiraki group were (50.00±8.03) min and (40.30±9.27) min, respectively.The operative time was significantly different between 2 groups ( t=4.107, P<0.05). The increased length of the exposed part of the penis after operation was (1.80±0.30) cm in the modified Sugita group and (1.90±0.33) cm in the modified Shiraki group, and no significant difference was found between the 2 groups ( P>0.05). Six months after operation, the parental satisfaction score was (4.60±0.56) points in the modified Sugita group and (4.60±0.59) points in the modified Shiraki group.There was no significant difference in the parental satisfaction score between 2 groups ( P>0.05). In 72 cases, only 5 cases had grade Ⅰ complications.Postoperative complications were also not significantly different between the 2 groups ( P>0.05). Conclusions:After treating severely concealed penis in children with modified Sugita and modified Shiraki, the penis has a good appearance.These two surgeries have high parental satisfaction and low complications.They are easy to implement in clinical practice.The operation time of modified Shiraki is shorter than that of modified Sugita.

Objective:To investigate the application effect of the compound flap transfer in tubularized incised plate (TIP) urethroplasty.Methods:Children with hypospadias who received TIP in the Department of Pediatric Urology, the Affiliated Xuzhou Children’s Hospital of Xuzhou Medical University from January 2018 to March 2022 were prospectively divided into compound flap transfer group (group A) and traditional TIP group (group B) by random number method. Group A was treated with TIP modified by compound flap transfer, and group B was treated with traditional TIP covered with fascia.The improvement of the compound flap transfer for TIP operation is mainly reflected in the multi-layer cover of the new urethra and the free skin embedded in the incision of the penile head. According to the intention-to-treat (ITT) principle, the final full analysis set (FAS) includes both group A and group B. Some patients were excluded from the analysis of the primary endpoint events due to reasons such as loss to follow-up or treatment group switch. Additionally, the final per-protocol set (PPS) consisting of group A and group B, which adheres to the study protocol, is subjected to statistical analysis.Independent sample t-test or Wilcoxon rank sum test was used for average age, the width of the penile head, degree of chordee, length of neourethra, and operative time. The classification of hypospadias, proportion of dorsal tunica albuginea plication, and incidence of postoperative complications were compared using the Chi-square test or Fisher’s exact test, P < 0.05 was considered statistically significant. Results:According to ITT principles, 50 children were included in FAS group A, ranging in age from 8 months to 15 years and 2 months, with an average age of 4 years. Group B included 50 children, ranging in age from 10 months to 14 years and 9 months, with an average age of 4 years and 1 month. Thirty-seven children in PPS group A were included, ranging in age from 1 year 2 months to 12 years 1 month, with an average age of 4 years. Group B consisted of 41 children, ranging in age from 1 year 2 months to 11 years 9 months, with an average age of 4 years 2 months. Statistical analysis showed that no matter FAS set or PPS, there were no statistically significant differences in the mean age, hypospadias type, average penile head width, average penile subcurvature number, number of dorsal tunica albuginea plication, and the average length of plastic neourethra between group A and group B ( P > 0.05). The average operative time of group A was higher than that of group B. The difference was statistically significant ( P < 0.05). The postoperative follow-up was 3 to 48 months, with an average follow-up of 2 years and 3 months. The complication rate of group A was lower than that of group B [10.81% (4/37) vs 29.27% (12/41)], and the difference was statistically significant ( P< 0.05). Urethral fistula occurred in 3 cases (8.11%), respectively and 6 cases (14.63%) in the two groups, the difference was not statistically significant ( P>0.05); urethral stricture occurred in 1 case (2.70%) and 5 cases (12.20%) respectively, the difference was not statistically significant ( P>0.05), There were 0 case and 1 case (2.44%) of urethral orifice descending or urethral dehiscence respectively, and the difference was not statistically significant ( P> 0.05). Conclusion:TIP with an improved compound flap transfer can reduce the overall postoperative complication rate and is worthy of promotion.
