Cystocentesis, mostly applied to acute urinary retention due to various causes, where the patient is unable to urinate and a drainage tube cannot be placed through the urethra, is an emergency procedure. It is divided into two types: i. Cystocentesis and drainage, i.e., puncturing into the bladder through the body surface to aspirate urine from the bladder and alleviate the patient’s urinary retention symptoms without leaving any tube after the puncture, and the cost of such procedures is about 300 yuan. Second, cystostomy, which is a puncture into the bladder through the body surface and a drainage tube is left in place to be worn for a short or long period of time, the cost of this type of procedure is about$900-1000. Both procedures are performed under local anesthesia and take about 15-20 minutes to perform, which is relatively safe and reliable, and the drainage is continuous and reliable.
