Abstract

Cryptorchidism is a common congenital urogenital anomaly, and accurate localization of undescended testes is essential for appropriate surgical planning. Magnetic resonance imaging may help identify non-palpable or ectopic testes before surgery. Objective: To determine the diagnostic accuracy of magnetic resonance imaging in cases of cryptorchidism, keeping surgical findings as the gold standard. Methods: This study was carried out on 69 male patients aged 1 to 25 years with suspected cryptorchidism, using non-probability sampling, in the Department of Radiology, Lady Reading Hospital, Peshawar, from 5 July 2024 to 5 January 2025. Patients with ambiguous genitalia or scrotal erythema and swelling were excluded. All patients underwent MRI on a 1.5 Tesla Toshiba Vantage scanner. MRI findings were compared with surgical findings for assessing diagnostic accuracy. Data were analyzed with SPSS 26. Diagnostic accuracy was calculated from a 2×2 contingency table. Results: The mean age of the patients in the present study was 11.55 ± 6.30 years. Surgical findings confirmed cryptorchidism in 29 patients (42.0%), while MRI was positive in 32 patients (46.4%). The sensitivity was 79.31%, the specificity was 77.50%, the positive predictive value was 71.88%, the negative predictive value was 83.78%, and the diagnostic accuracy was 78.26%. Conclusion: The diagnostic accuracy of magnetic resonance imaging in diagnosing cryptorchidism in the present study was 78.26%, with a sensitivity 79.31% and a specificity 77.50%, taking surgical findings as the gold standard.
