Insights
Stretched penile length (SPL) in hypospadias patients was compared to normal children. Proximal hypospadias showed a statistically significant difference in SPL compared to age-matched norms.
Area of Science:
- Pediatric Surgery
- Urology
- Developmental Biology
Background:
- Stretched penile length (SPL) is a critical metric for hypospadias evaluation.
- Hypospadias is a congenital condition affecting penile development.
Purpose of the Study:
- To determine if there is a difference in SPL between hypospadias patients and age-matched normal children.
- To assess the clinical utility of SPL measurements in hypospadias management.
Main Methods:
- A cross-sectional study involving 100 hypospadias patients under 14 years old.
- SPL was measured using digital vernier calipers and compared to SPL nomograms.
- Statistical analysis, including P-value calculation, was performed to determine significance (P < 0.05).
Main Results:
- One hundred patients (mean age 3.72 years) were analyzed, categorized by hypospadias severity (distal, mid, proximal).
- A statistically significant lower proportion of proximal hypospadias patients matched the age-matched SPL nomogram.
- This finding suggests potential differences in penile growth associated with hypospadias severity.
Conclusions:
- SPL measurement is significant in preoperative planning for hypospadias repair.
- A personalized treatment approach is essential for optimizing outcomes in hypospadias surgery.
- Further research may explore the correlation between hypospadias subtypes and penile length deviations.
Background:
Stretched penile length (SPL) is a crucial metric in evaluating hypospadias. In this study, we aim to find whether there was any difference in the SPL in hypospadias patients when compared to the SPL of normal children of the same age group.
Materials And Methods:
This cross-sectional analytical study was done in the department of pediatric surgery at a tertiary institution in central India from November 2022 to April 2024 over a period of 18 months. All preoperative hypospadias patients under 14 years of age who underwent hypospadias repair were included in the study. The SPL was measured in supine position using the digital vernier calipers for accurate measurement and compared with the SPL of the normal healthy people of the same age group with the SPL nomogram. P value was then calculated (Statistical significance at P < 0.05) based on the number of patients who matched the SPL of the same age group as per the nomogram.
Results:
One hundred patients (46 patients with distal penile hypospadias, 19 mid-penile hypospadias, and 35 proximal penile hypospadias) with a mean age of 3.72 years were included in the study. Based on P values, lesser number of patients with proximal penile hypospadias were found to be matching with the SPL as per the nomogram, the proportion being statistically significant.
Conclusion:
This study highlights the significance of SPL measurement in preoperative planning of hypospadias repair, emphasizing the need for a personalized treatment approach to achieve better outcomes.
