Popis: Abstract Objective The study aims to evaluate the usefulness of preoperative ultrasonography (US) at the internal inguinal ring level in predicting contralateral patent processus vaginalis (CPPV). Methods This is a prospective study of patients who presented with unilateral inguinal hernia and underwent laparoscopic hernia repair and contralateral side exploration. The gender, age, initial presenting side, and the preoperative width of the low echoic region at the internal ring (WLIR) of the contralateral side that was determined using US and laparoscopic findings were recorded. The preoperative diagnosis of CPPV was considered if the WLIR is > 4 mm. We compared laparoscopic with US findings. Results This study included 30 patients with a median age of 3.5 years (range, 25 days to 10 years), with 3 females and 27 males. The preoperative US and laparoscopic diagnoses of the contralateral side were concordant in 19 (63.3%) and discordant in 11 (36.6%) patients. US showed a sensitivity of 50.00%, specificity of 72.22%, and accuracy of 63.3% in diagnosing CPPV. Conclusions Measuring the WLIR by US was inadequate for an accurate CPPV diagnosis in our study. Therefore, more distinctive US criteria are required for a proper CPPV diagnosis.
