Parapelvic cysts originate in the renal parenchyma and extend into the renal sinus. A series of 3 patients with symptomatic obstructing parapelvic cysts is described, 2 with acute presentations, and 1 with chronic symptoms. In 2 of the 3 cases, there was a significant delay in establishing a diagnosis. Although one individual was successfully managed by image-guided cyst aspiration, the second patient required repeated aspiration due to cyst re-accumulation. A high index of clinical suspicion and a combination of imaging modalities, including serial ultrasound, excretory-phase CT, and MAG3 renogram, are necessary to establish the diagnosis and monitor response to treatment.
肾盂旁囊肿起源于肾实质并延伸至肾窦。本文描述了3例有症状的梗阻性肾盂旁囊肿患者，其中2例为急性表现，1例为慢性症状。3例中有2例在确诊时出现了明显延误。尽管1例患者通过影像引导下囊肿穿刺抽吸成功治愈，但第2例患者因囊肿复发需要反复抽吸。高度的临床怀疑以及包括系列超声、排泄期CT和MAG3肾图在内的多种影像学检查相结合，对于确诊和监测治疗反应是必要的。
