Clinical data were retrospectively collected from patients who underwent hypospadias repairs with urethral plate transection between March 2017 and June 2023. Patients were divided into VL group and VL\u2009+\u2009DP group based on the curvature correction techniques. Two novel parameters\u2014penile lengthening ratio (PLR) and curvature-adjusted penile lengthening ratio (CPLR)\u2014were introduced to evaluate the effectiveness of penile lengthening. A total of 103 male patients with hypospadias and severe ventral curvature were included. In patients with a curvature degree after degloving (CDAD) greater than 45\u00b0, the CPLR was significantly higher in the VL group compared to that in the VL\u2009+\u2009DP group (0.0101\u2009\u00b1\u20090.0028 vs. 0.0085\u2009\u00b1\u20090.0024, p\u2009=\u20090.026). Among patients with proximal hypospadias, the CPLR in the VL group was significantly higher than that in the VL\u2009+\u2009DP group (0.0106\u2009\u00b1\u20090.0024 vs. 0.0093\u2009\u00b1\u20090.0026, p\u2009=\u20090.041).
