The invention discloses a tissue morcellation lithotriptoscope which comprises an operation pipe, an endoscope, a lighting channel and a scope sheath, an operation channel is axially arranged on the operation pipe, the endoscope and the lighting channel are arranged on the operation pipe, the scope sheath is detachably sleeved on the front section of the operation pipe and can be matched with a resectoscope, a water passing channel is formed between the outer wall of the operation pipe and the inner wall of the scope sheath, and a water inlet channel communicated with the water passing channel is axially arranged on the wall of the operation pipe. Firstly, by the aid of the tissue morcellation lithotriptoscope, only the scope sheath needs to be inserted into a urethra once in the whole surgery process, multiple injuries of the urethra due to the fact that instruments such as the resectoscope and the lithotriptoscope repeatedly enter the urethra are avoided, and the amount of bleeding is greatly reduced. Secondly, 1/3-1/2 surgical time can be saved in the whole surgery process, the labor intensity of doctors is greatly relieved, and the risk and the pain of a patient are greatly reduced. Thirdly, morcellated tissues and broken stones can be simultaneously exenterated by the aid of different water circulation, and a novel surgical operation mode is developed.
