In this study, I proposed of an engineering analysis methods due to interference effect within the cyst by ultrasound in the renal ultrasonography. Experimental results, the human can not be found to distinguish interference caused by the ultrasonic echoes within the cyst. The proposed method is used, then in the cyst appears insignificant signal can distinguish the difference. Thus, the misdiagnosis can be prevented in advance.

Tailgut cysts are known to originate from the remnants of the embryonic hindgut. They occur exclusively in the retrorectal and presacral spaces. There have been limited reports of tailgut cysts occurring in the left perirenal space. The present case features a huge tailgut cyst extending from the right perirenal to the perivesical space. We believe that this case report will help to further elucidate the characteristics of perirenal and perivesical tailgut cysts.

Meralgia paresthetica (MP) is a benign entrapment neuropathy which is characterized by sensory impairment and paresthesia in the cutaneous distribution of the lateral femoral cutaneous nerve. A 79-year-old woman presented with intermittent right inguinal burning sensation. The sensory nerve conduction study (NCS) showed decreased right side sensory nerve action potential (SNAP) on lateral femoral cutaneous nerve compared to the contralateral one. Abdomino-pelvic CT showed bilateral huge renal cysts (The size of largest one on right side: about $6.2{\times}5.0cm$). We report a case of MP caused by a huge abdominal renal cyst, which should be considered when conventional examination reveals no responsible etiology.
