Tc-ethylenedicysteine (Tc-EC) diuretic renal scintigraphy is an established, safe, and noninvasive study to evaluate relative renal function and drainage. We present a known case of bilateral renal stone disease who presented with acute urinary obstruction detected intraprocedurally on Tc-EC diuretic renography. He was managed subsequently with emergency double J stenting. The development of acute obstruction intraprocedurally in this patient may be resultant of forced diuresis caused by furosemide, dislodging the renal stones in the distal ureters. In the setting of renal calculi, cautious use of furosemide with watchful monitoring may be needed to see for the development of obstruction and manage accordingly.
锝-乙二巯基丁二酸（Tc-EC）利尿肾动态显像术是一项成熟、安全且无创的检查，用于评估相对肾功能和引流情况。我们报告一例已知的双侧肾结石病病例，该患者在Tc-EC利尿肾图检查过程中被发现存在急性尿路梗阻。随后对其进行了急诊双J管置入术治疗。该患者在检查过程中出现急性梗阻，可能是由于速尿引起的强制利尿导致远端输尿管内的肾结石移位所致。在肾结石的情况下，可能需要谨慎使用速尿并密切监测，以观察是否出现梗阻并相应地进行处理。
