作者1981年1月～1985年6月通过普通膀胱镜用Dormia套石篮为结石距输尿管口4～5cm内的170名住院患者行经尿道取石,其中46名需行输尿管口切开取出结石,12名结石嵌顿在壁段输尿管,其余者套石篮和被套住的结石嵌顿在下段输尿管。 Sachse尿道刀的刀刃向上,将刀片放入输尿向口,沿输尿管走向插入,然后器械远端向下压管,使刀片的角向上顶住壁段输尿管,沿输尿管嵴低膀胱内输尿管开口处切开。这一过程可通过一次少切一点组织重复地进行,直到看见结石和结石排出,或者嵌顿的套石篮取出。对于套石篮挂住者,可松动其近端的手柄,将Dormia套石篮鞘取出,采用缓慢牵引显露导丝,直到套石篮被拖至输尿管口。然后向前述的那样切开输尿管口的顶部,通常容易取出。病人术后无明显泌尿系症状和尿路感染表现,未置输尿管支架。
Author from January 1981 to June 1985 through the general cystoscope with Dormia stone basket for stones within 4 ~ 5cm from the ureteral orifice of 170 inpatients urethral lithotomy, of which 46 required ureteral incision and removal of stones, 12 Stone impacted stones in the wall of the ureter, the other set of stone baskets and stones were trapped in the lower ureter. Sachse Urethral knife blade up, the blade into the ureter to the mouth, along the ureter to insert, and then the distal end of the instrument tube, the blade angle to withstand wall ureter, along the ureteral crest low vesical ureter opening Cut This process can be repeated by cutting the tissue a little at a time until it is seen that stones and stones have been removed or that an incarcerated stone basket has been removed. For those who stay in a stone basket, loosen the proximal handle and remove the Dormia hemi-glove sheath, revealing the guide wire slowly, until the stone basket is pulled over the ureteral orifice. The top of the ureteral orifice is then dissected as previously described and is usually easily removed. No obvious urinary tract symptoms and urinary tract infection in patients after surgery, not placed ureteral stent.
