The invention provides a prostatic dilation catheter with an internal capsule shifted forwards. A main catheter, an internal capsule and an external capsule are arranged. A urinary catheter, a flushing pipe, an internal capsule tube, an external capsule tube and a location protrusion are arranged in the main catheter. The main catheter is provided with an internal capsule water injection port and an external capsule water injection port. The internal capsule tube and the external capsule tube are connected with the internal capsule water injection port and the external capsule water injection port respectively. The front end of the main catheter is provided with a urine guide opening and a flushing opening. The external capsule is located between the flushing opening and the location protrusion, the internal capsule is located in the external capsule, and the tail end of the internal capsule and the tail end of the external capsule are arranged at intervals. The tail end of the internal capsule and the tail end of the external capsule are arranged at intervals, the main catheter can be placed at a preset position through the internal capsule and the location protrusion, so that the internal capsule can still slide in the prostate after water pre-infusion; when the internal capsule having undergone pre-infusion abuts against the external urethral sphincter, the un-expanded external capsule can be at an appropriate position, so that subsequently the external capsule can split a prostatic evacuating catheter from the external urethral sphincter to the position of the bladder conveniently, a better dilation is achieved, and the prostatic dilation accuracy is improved.
