Abstract

Renal cysts, which are commonly detected incidentally on imaging, often remain asymptomatic. A small percentage may lead to complications such as hemorrhage, infection, or mass effect. This can cause elevated intrapelvic pressure and possible spontaneous rupture, which can establish a communication with the calyceal system. This report presents the case of a 79-year-old male with urothelial carcinoma who developed right-sided hydronephrosis secondary to obstructive malignancy. CT and fluoroscopic imaging revealed a large urinoma with a communication between the collecting system and adjacent renal cyst. Following nephrostomy tube decompression, the presence of contrast within the renal cyst that helped establish the initial communication disappeared and was unable to be re-established. This disappearance contrasts the continued communication seen with typical renal cyst communications and may have occurred due to possible pressure related mechanisms.

肾囊肿交通退化继发于输尿管积水减压术1例。

肾囊肿通常在影像学上偶然发现，通常没有症状。一小部分可能导致并发症，如出血、感染或肿块效应。这可能导致盆腔内压力升高，并可能自发破裂，从而与肾盏系统建立联系。本文报告一例79岁男性尿路上皮癌并发右侧肾积水，继发于梗阻性恶性肿瘤。CT和x线透视显示一个大的尿瘤，在收集系统和邻近的肾囊肿之间有交通。肾造口管减压后，肾囊肿内帮助建立初始通信的造影剂消失，无法重新建立。这种消失与典型肾囊肿通信的持续通信形成鲜明对比，可能是由于压力相关机制造成的。
