Abstract

Purpose

One of the most important complications of undescended testis (UDT) surgery is testicular atrophy (TA). We aimed to investigate the factors associated with TA in children who underwent orchiopexy for unilateral UDT.

Methods

The data of 215 patients aged < 15 years who underwent orchiopexy for unilateral UDT between November 2019 and September 2022 were analyzed retrospectively. Clinical, radiological, surgical, and follow-up findings were recorded.

Results

TA was observed in 29 (13.5%) patients. Mean resistive index (RI) values were 0.44 ± 0.06, 0.54 ± 0.09 and 0.69 ± 0.1 in low, middle and high testicular locations, respectively, and intratesticular RI increased significantly as the testis location raised (p < 0.001). After orchiopexy, the mean testis volume ratio (TVR) increased significantly (0.63 ± 0.13 vs. 0.77 ± 0.15, p < 0.001). Besides, the mean RI values decreased significantly in the postoperative follow-up (0.53 ± 0.12 vs. 0.47 ± 0.13, p < 0.001). In multivariate regression analysis, testicular high location (OR 4.332, 95% CI 2.244–6.578, p = 0.002), deferens-epididymal anomaly (OR 3.134, 95% CI 1.345–7.146, p = 0.021), TVR ≤ 0.5 (OR 5.679, 95% CI 2.953–12.892, p < 0.001) and RI ≥ 0.6 (OR 7.158, 95% CI 3.936–14.569, p < 0.001) were independent predictive factors for TA after orchiopexy.

Conclusion

Higher testis location, deferens-epididymis anomaly, preoperative TVR and RI were independent predictive factors for TA after orchiopexy in unilateral UDT. The results of the study will help surgeons to predict TA before orchiopexy.
