Background: During the COVID-19 crisis, there has been widespread reporting that non-COVID-19-related medical care has been delayed, even for emergent conditions. Testicular torsion is an emergent condition with higher risk of testicular loss with longer ischemic times. We sought to investigate whether patients with testicular torsion had longer time from symptom onset to initial presentation, longer total ischemic time, and higher rate of orchiectomy during the pandemic., Materials and Methods: Using billing data, we identified all patients age >1yo seen in our hospital from 1/1/2018 through 5/31/2020 who underwent emergent scrotal exploration for confirmed testicular torsion, comparing the COVID-19 crisis (3/1/2020-5/31/20) to the pre-COVID-19 period (1/1/2018-2/29/20). The primary outcome was time from symptom onset to initial presentation and secondary outcomes were ischemic time (time from symptom onset to entry of the OR) and orchiectomy rate. Parameters were compared with Mann-Whitney U and Fisher's exact tests; Poisson regression compared rates of torsion., Results: Of 94 total cases, 77 occurred during the pre-COVID-19 period and 17 during the COVID-19 crisis. Median time from symptom onset to initial presentation was not significantly different (2.4 h [IQR 1.1 h-38.9] during COVID-19 vs. 5.6 h [IQR 1.6-16.9] during pre-COVID-19 period, p = 0.476). Time to presentation was >12 h in 5/17 patients (29%) during COVID-19 and 24/77 patients (31%) during pre-COVID-19 period (p = 1.00). Median ischemic time during COVID-19 was 7.5 h (IQR 4.7 h-45.5 h) compared to 9.4 h (IQR 5.4 h-22.5 h) during pre-COVID-19 period (p = 0.694). Incidence of orchiectomy in our center was 29% (5/17) during COVID-19 and 17% (13/77) during pre-COVID-19 period (p = 0.397). About half of patients were seen initially at outside facilities prior to arrival (47% [8/17] during COVID-19 vs. 49% [38/77] during pre-COVID-19 period, p = 1.00). The number of torsion case presentations per week to our facility increased from 0.7 cases/week in the pre-COVID-19 period to 1.3 cases/week during COVID-19 (p = 0.015); when comparing only the March 1 to May 31 calendar period, there were 0.6 cases/week during the pre-COVID-19 period and 1.3 cases/week during COVID-19 (p = 0.021)., Conclusion: Time to presentation, ischemic times, and orchiectomy rates for testicular torsion at our center were not significantly different during the COVID-19 period compared to the preceding 2 year period. The number of torsion case per week presenting to our facility increased significantly., Competing Interests: Conflict of interest None., (Copyright © 2020 Journal of Pediatric Urology Company.

Objective: We hypothesized that cold ischemia during partial orchiectomy would lead to higher serum testosterone levels and preservation of testicular architecture than warm ischemia in a prepubescent rat model., Materials and Methods: Eighteen prepubescent male Sprague-Dawley rats were randomized to three different surgical groups: sham surgery, bilateral partial orchiectomy with 30 min of cord compression with cold ischemia, or bilateral partial orchiectomy with 30 min of cord compression with warm ischemia. Animals were killed at puberty, and serum, sperm, and testicles were collected. Histological tissue injury was graded by standardized methodology., Results: Mean serum testosterone levels were 1445 ± 590 pg/mL for the sham group, 449 ± 268 pg/mL for the cold ischemia group and 879 ± 631 pg/mL for the warm ischemia group (p = 0.12). Mean sperm counts were 2.1 × 10(7) for sham, 4.4 × 10(6) for cold ischemia, and 9.9 × 10(6) for the warm ischemia groups (p = 0.48). Histological evaluation revealed significant difference in tissue injury grading with more injury in the cold ischemia than in the warm ischemia group (p = 0.01)., Conclusions: In our preclinical rat model, we found no benefit for cold ischemia over warm ischemia at 30 min., (Copyright © 2014 Journal of Pediatric Urology Company.
