摘要

自發性輸尿管破裂是很少發生的，而且被認為是尿液非受傷性地從輸尿管漏出，它通常是因為結石造成輸尿管的阻塞，症狀比較嚴重，治療需要引流或者手術。真正的上輸尿管或腎盂破裂可能和腎盞穹窿尿液外滲的生理現象混淆。腎盞穹窿外滲也常導因於輸尿管結石，相對於輸尿管破裂，腎盞穹窿外滲較常看到而且症狀較輕微，保守性的處理是治療的原則。因為過程和治療方式不同，區別這兩種情況顯得非常重要。我們報告三個因為結石造成罕見的自發性輸尿管破裂以及一個不尋常地由於急性膀胱膨脹造成腎盞穹窿外滲的病例，並且討論這兩種情況的不同。

Spontaneous rupture of the ureter is extremely uncommon and thought as a nontraumatic leakage of the urine from the ureter. It is usually secondary to ureteral obstruction from a calculus. The symptom is always severe and drainage or surgical intervention is often required. True rupture of upper ureter or renal pelvis may be confused with a physiologic phenomenon of the forniceal rupture with urine extravasation. Forniceal extravasation is also mainly due to ureteral stone. In contrast to ureteral rupture, forniceal extravasation is more commonly seen and the symptom is always mild. Conservative management is the principle of treatment. A clear distinction between these two conditions becomes very important since both course and treatment are different. We present 3 cases of rare spontaneous rupture of the ureter with calculus disease and a case of forniceal extravasation unusually due to acute urinary bladder distension. Difference between these two conditions is discussed.
