To examine whether scrotoscopy could be used to diagnose testicular rupture (TR) with accuracy.This retrospective study included all patients receiving scrotoscopy followed by immediate open exploration (OE) for suspected TR at two Chinese tertiary care centers between March 2014 and March 2018.Fifteen patients suspected of having TR were included. TR was considered in 8 patients (8/15) via emergency scrotal ultrasound (ESU) examination. Of these 8 patients, 6 cases as well as 3 other cases, a total of 9 cases (9/15) were confirmed TR by scrotoscopy and OE; the remaining 6 patients (6/15) were found disease free. The presence/absence of TR was identified correctly with scrotoscopy in all 15 cases. The rupture size of the testicular tunica albuginea (TTA) varied from 0.5 to 2 cm. Only 3 cases (3/15) had scrotal wall edema and all quickly recovered. The testis was normal in size and blood flow at 6-month follow-up visit.Scrotoscopy accurately diagnoses TR, and may avoid unnecessary OE, especially for the patients confirmed free of disease.
