Pelvic cysts should be referred to as parapelvic cysts. Smaller cysts can be followed up regularly, while larger cysts are generally recommended to be treated by surgery. 1. For small and asymptomatic cysts, regular checkups and close follow-ups are recommended. 2. Surgery is recommended for larger cysts that locally compress the renal pelvis and calyces and cause clinical symptoms, and common surgical methods include: (1) Open parapelvic cyst decapitation and decompression, the technology has been mature, the operation is relatively simple, the anatomical structure is clear, and the postoperative complications are relatively few. However, the incision is large and traumatic, and the postoperative recovery time is long. (2) Laparoscopic surgery, which has become the mainstream procedure for the treatment of parapelvic cysts, has a low recurrence rate. Due to the deep location and complex anatomical relationship, intraoperative operation still requires fine manipulation and careful identification to avoid damage to the renal pedicle vessels and renal pelvis. (3) Percutaneous nephrolithotomy with internal drainage, small incision, but requires the operator to be familiar with the technique of renal puncture under ultrasound localization, which requires percutaneous puncture through the cyst and into the renal pelvis, and also carries the risk of injury to the renal hilum vessels and the surrounding organs. If you have a renal pelvic cyst on examination, you should consult your doctor for further diagnosis and treatment, so as to avoid any delay in your condition.
