Comparison of clinical effects between microscopic surgery and conventional surgery in children with penile hypospadias and difference analysis of postoperative urodynamics

OBJECTIVE: To compare and analyze the clinical effects of microscopic surgery and conventional surgery in children with penile hypospadias and the differences in postoperative urodynamic indexes. METHODS: It was a clinical comparative study. A total of 80 children with penile hypospadias admitted to Beijing Children’s Hospital Affiliated to Capital Medical University Baoding Hospital from July 2018 to September 2022 were selected and randomly divided into two group. The experimental group were treated with microscopic urethroplasty, while the control group were treated with traditional urethroplasty. The operative effect, operation time, total intraoperative blood loss, postoperative hospital stay and incidence of surgical complications were compared and analyzed between the two groups. All the children were followed up for two years, and the changes in urodynamic parameters including maximum urine flow rate (Qmax), average urine flow rate (Qavc), urine flow time (FT), peak time (TQmax) and residual urine (PVR) were compared before, two weeks after, six months after and two years after surgery. RESULTS: The efficacy of the experimental group was significantly higher than that of the control group (p=0.013). The intraoperative blood loss and postoperative hospital stay in the experimental group were significantly better than those in the control group (p=0.000). The incidences of urinary leakage and urethral stricture in the experimental group were lower than those in the control group (p<0.05). The Qmax level in the experimental group was higher than that in the control group at six months and two years after surgery, while the FT level was lower than that of the control group (p<0.05). CONCLUSION: Microscopic surgery is a method with significant clinical value in the treatment of penile hypospadias.
