Laparoscopic Anderson-Hynes dismembered pyeloplasty in children using needlescopic instrumentation

The technique of needlescopic Anderson-Hynes dismembered pyeloplasty is dis cussed. The recent development of robust 3-mm needlescopic instruments desi gned to perform dismembered pyeloplasties has added a new dimension to lapa roscopic suturing and will significantly enhance the ability to perform mic roanastomosis-the limiting factor preventing many surgeons from performing this technically demanding operation. The use of such fine instrumentation also reduces the size of instrument cannulae necessary, further reducing th e postoperative pain and results in spectacular postoperative cosmetic appe arance.
