ABSTRACT
OBJECTIVE: To evaluate the application and effect of the lateral preputial fascial island flap (LPFIF) in hypospadias reoperation.
METHODS: We retrospectively analyzed the clinical data on the children patients undergoing hypospadias reoperation with LPFIF in our Department of Urology from December 2016 to June 2019.
RESULTS: A total of 85 cases were included in this study, including 18 cases of LPFIF, 19 cases of Duplay technique, 25 cases of tubularized incised plate urethroplasty (TIP) and 23 cases of Mathieu urethroplasty. The patients were aged from 18 months to 12 years and 8 months, averaging 4.6 years. Postoperatively, all the children were followed up for ≥ 6 months, which found satisfactory appearance of the penis body and glans, the urethral orifice in the normal position of the glans, and the external orifice of the urethra fissured. Urethral fistula occurred in 2 cases and glans dehiscence in 1 after LPFIF; 5 of the patients presented urethral fistula after Duplay; 3 developed urethral fistula and 1 urethral stricture after TIP; 6 showed urethral fistula and 2 glans dehiscence after Mathieu urethroplasty. No postoperative urethral stricture, urethral diverticulum or flap necrosis occurred in any of the cases. Hypospadias reoperation succeeded in 83.3% (15/18) of the cases after LPFIF. The urine flow curve of the LPFIF cases was bell-shaped or high flat-shaped, with a maximum urinary flow rate of 8.56 ± 3.99 ml/s and an average urinary flow rate of 5.23 ± 2.32 ml/s, not significantly different from those of the TIP and Duplay cases.
CONCLUSIONS: There is no statistically significant difference in the success rate of hypospadias reoperation between TIP and LPFIF. Urethroplasty with LPFIF can be used as one of the surgical options for hypospadias reoperation.
