Abstract EN
Introduction : Undescended testis is a major clinical problem in male infants as long-term retention of undescended testis is associated with dramatically increased risk of testicular neoplasm, especially seminoma.
In addition, undescended testis will alter the male fertility.
Aim of the work : To compare the results of the two imaging modalities (US & MRI) in localization of undescended testicles to chose the line of treatment.
Patients and Methods : Our current study included 30 male patients with age range between 3 months up to 25 years.
Clinically, the undescended testicle was RT.
Sided in 12 patients (40 %), LT.
sided in 10 patients (33.3 %) and bilateral in 8 patients (26.7 %).
All the 30 patients were examined firstly with ultrasound followed by MRI.
The findings were recorded and compared based on surgical findings.
Results : US succeeded in localizing the undescended testis in 25 cases (25 / 30 = 83.3 %) and did not detect 5 cases (5 / 30 = 16.7 %).
12 cases were atrophied on US (12 / 30 = 40 %).
Sensitivity was.
(89.3.6 %), specificity (100 %) and accuracy (90 %).
The US locations of the 25 cases were 14 cases within inguinal canal, 7 cases adjacent to the superficial inguinal ring & 4 cases adjacent to the internal inguinal ring.
MRI succeeded in localizing the undescended testis in 28 cases (28 / 30 = 93.3 %) and did not detect 2 cases (6.7 %), anorchia (testicular agenesis).
16 cases were atrophied on MRI (53.3 %).
Sensitivity was (100 %), specificity (100 %) and accuracy (100 %).The MRI location of the detected cases were 15 cases within inguinal canal (15 / 30 = 50 %), 8 cases adjacent to superficial inguinal ring (8 / 30 = 26.7 %) & 4 cases adjacent to internal inguinal ring (4 / 30 = 13.3 %) and one case was ectopic intra-abdominal.
On surgery 28 undescended testicles were detected (consuistent with MRI findings).
2 cases were truly absent (agenesis) on exploration.
Conclusion : MRI is a new modality for localization of undescended testicles because; it is safe, multiplanar & high resolution.
MRI with IV contrast injection is helpful especially in suspected cases with atrophy.
Ultrasound must be used first, as both modalities are complementary to each other.
