The urodynamical checkup document, obviously is 腹压排尿。The maximum urine rate after the operation is 8cc/s, residual .... 200cc. Obviously there is no effect.

Last October, Xiao was invited to give a presentation on the 30th anniversary of the Institute of Urological surgery at the Peking University. He showed his video. But it was more like a commercial to me. In the video, a mother from the US told her story after (his daughter's ???) operation. It was not a scienfitic presentation.

He got a fairly large grant at the US, and wanted to study 40 cases. We have not see his final report till 2009. His reports on AUA were all abstracts, which tell you little.

As far as the urological community within the academics in our country is concern, the Xiao procedure is not very well accepted. Otherwise, we have popularized the procedure long time ago. It was probably at Kunming the year, where the national conference on urology was held the year before the last. Xiao Chuanguo was there and gave a presentation. Songbo commented afterwards, made some rather objective remarks on his operations. We run into each other on all kinds of occasions, so it is hard not to 'save some face' for Xiao Chuanguo. It was all between us as to how to handle this. It would be easier when back against back, but harder when face to face. We do not want to corner him. On the conference, Song Bo's comments refrained from completely endorsing his procedure. The evaluation that I did, the one in Wuhan in 2004, involved six academicians. His documents included two parts, fundamental research and clinical research.

The third letter, whose author specializes in neurology, gives a relatively objective comment. He was sure of one point, that the establishment of the reflex arc was out of the question; the reflex arc has no effect at all.

If the Xiao procedure is not effective, urination still depends on the bladder pressure and 腹压 after the operation. Time and again, it could do damages to 上尿路（对输尿管，肾脏）. It relies on the huge bladder pressure, instead of the pressure from 逼尿肌。久而久之，就可能产生膀胱输尿管反流，肾脏的积水，输尿管的积水会增加，对肾功能是有损害的，危害也是在这个地方。

Besides, with the normal 神经支配 cut, there are questions such as whether it would lead to ED, or how the erectile function is affected, after the children have grown up. For these reasons, the opertiaon is very controvesial.
