Abstract：Objective： To investigate the clinical efficacy of the Mathieu procedure under microscope in the treatment of penile hypospadias. Methods： A retrospective analysis of 53 patients with penile hypospadias in our urology department from January 2016 to June 2019 was done. According to whether the procedure was operated under the microscope, the patients were divided into the study group （n = 33） and the control group （n = 20）. The study group was given the Mathieu urethroplasty under the ZEISS 88 microscope, and the control group traditional Mathieu urethroplasty. The efficacy and complications of the two groups were compared. Results： The length of urethral reconstruction in the study group was （2.9 ± 1.1） cm, and the width of urethral plate was （1.4 ± 0.5） cm. One case of urinary fistula occurred after operation, and the urethral fistula was repaired under the microscopy. One case had a dehiscence of the external urethra and shifted to the coronal sulcus. There was no stenosis, the penis straightened well, and the complication rate was 6.1%. In the control group, the length of urethral reconstruction was （3.1 ± 1.2） cm, and the width of urethral plate was （1.5 ± 0.4） cm. Two cases of urinary fistula occurred after surgery, which was repaired under microscope, and two cases of postoperative stenosis were cured after urethral dilation. The penis straightened well in all patients after the operation, and the overall complication rate was 20%. Conclusion： The Mathieu proceure under the microscopy has a higher success rate and fewer complications than the traditional operation in the treatment of hypospadias, which is worthy of clinical promotion.
