摘要

背景：睪丸扭轉為泌尿科的急症需要早期診斷及早期手術治療；然而要早期鑑別急性睪丸扭轉和睪丸及副睪丸炎是不容易的。本回溯性研究的目的在於評估核醫陰囊掃描對於急性睪丸扭轉及發炎性疾病鑑別診斷的價值。
方法：從1999年7月到2001年7月共收集30位懷疑有急性睪丸扭轉的男性病人(年齡5歲至42歲)。最後的確定診斷是根據手術及病理學上的結果來決定而未接受手術的病人則由臨床上至少追蹤一個月。
結果：有八位病患為睪丸扭轉，18位病患是睪丸或副睪丸發炎而有四位是正常，這些病人的診斷都是經由手術後病理學上的證明或臨床的追蹤才確定診斷而核醫陰囊掃描全都正確的診斷出來。在核醫檢查時，所有病人沒有不適和副作用出現。
結論：核醫陰囊掃描檢查對於鑑別睪丸扭轉及睪丸或副睪丸發炎是一個有用且很準確的工具。

Background: Torsion of the testes is an urological emergency. This clinical condition requires early diagnosis and prompt surgical treatment for testicular survival; however, the early differential diagnosis of acute testicular torsion is often difficult. The aim of this retrospective study was to evaluate the value of technetium-99m pertechnetate radio nuclide imaging in the differentiation between acute testicular torsion and inflammatory testicular diseases.
Methods: Thirty male patients (age range: 5-42 years) with suspected acute testicular torsion were enrolled in this stud y between Jul y 1999 and Jul y 2001. Radionuclide imaging was performed after intravenous injections of5-15mCi of technetium-99m pertechnetate in the forearms. Then, all of the patients with clinically suspected acute testicular torsion underwent surgery. Surgical findings and pathology reports of these patients were reviewed and definite diagnoses were made. All of the patients who did not receive operation were followed up clinically for at least one month after radionuclide imaging.
Results: Eight patients with testicular torsion,18 patients with inflammatory testicular diseases, and 4 normal subjects were diagnosed by surgical findings, pathological results and/or clinical follow-up. All were accurately diagnosed by technetium-99m pertechnetate radionuclide scrotal imaging. No scintigraphy-related discomfort or side-effects were observed in any of the patients during the study.
Conclusions: Our results conclude that technetium-99m pertechnetate radionuclide scrotal imaging is a useful and accurate imaging modality in the differentiation between acute testicular torsion and inflammatory testicular diseases in patients with acute scrotum.
