Evaluating the Role of MRI in Localizing Undescended Testes: Retrospective Correlation with Operative Findings in an Indian Population

Abstract

Background:

Undescended testes (UDT) is a common congenital anomaly in male children. Accurate localization is critical for effective surgical planning. MRI, including Diffusion Weighted Imaging (DWI), offers potential advantages.

Objective:

To evaluate MRI, particularly with DWI sequences, in identifying non-palpable undescended testes and to compare imaging findings with intraoperative outcomes in Indian pediatric patients.

Methods:

This retrospective study included 32 patients. MRI (T1, T2, DWI sequences) findings were compared with intraoperative observations. Diagnostic accuracy and statistical measures were computed.

Results:

MRI correctly localized 29 of 32 testes. Testes appeared hypointense on T1, hyperintense on T2, and showed restricted diffusion on DWI. Sensitivity: 96.7%, Specificity: 100%, PPV: 100%, NPV: 66.7%, Accuracy: 96.9%. The Chi-square test yielded a p-value of 0.001.

Conclusion:

MRI with DWI significantly aids in UDT localization. Despite limitations, it remains a valuable preoperative tool.
