A Comparative Study on the Uroflowmetry Parameters between Single-stage and Staged Hypospadias Repair.

Area of Science:

• Pediatric Urology
• Surgical Outcomes Research

Background:

• Hypospadias repair aims to restore normal urinary function.
• Uroflowmetry is a key tool for evaluating functional outcomes post-surgery.

Purpose of the Study:

• To compare uroflowmetry parameters between single-stage and staged hypospadias repair.
• To identify any statistical differences in functional outcomes.

Main Methods:

• Prospective cohort study (July 2022 - July 2024).
• Uroflowmetry parameters assessed on postoperative Days 10, 30, and 60.
• Statistical analysis included paired t-tests and Chi-square/Fisher's exact tests (P < 0.05).

Main Results:

• Both single-stage and staged repairs showed increased mean flow rate and total voided volume.
• Maximum flow rate decreased over time in both groups (Day 10 to Day 60).
• A statistically significant difference in maximum flow rate was observed on Day 60 (P=0.08), favoring single-stage repair.

Conclusions:

• Uroflowmetry is valuable for assessing functional outcomes after hypospadias surgery.
• A statistically significant difference in maximum flow rate (Qmax) on Day 60 suggests potential urinary outflow obstruction with staged repair.
