ABSTRACT

Parapelvic cyst is a special type of cystic lesion of the kidney. Due to the characteristics of its anatomical relationship, parapelvic cyst can compress the collecting system or the blood vessels at the pedicle of the kidney in the early stage of the disease. Compared with other cystic diseases of the kidney, aggressive treatment should be taken earlier. Here, we report a patient with hydronephrosis secondary to renal pelvis and parapelvic cyst compression at the ureteropelvic junction was admitted to our hospital. Laparoscopic left pyeloureteroplasty was performed after condications were ruled out. During the operation, a cystic mass was observed between the two renal pelvis. There was no stenosis or dilatation in the upper part of the left ureter. In conclusion, considering the long-term compression of cysts between the renal pelvis of the two branches of the UPJO system in the patient, laparoscopic parapelvic cysts of the left side were performed.
