Microsurgery in clinical urology.

Microsurgery is not a new tool to the urologist. Transurethral resection is probably the most challenging type of microsurgery, and we do it daily. The manipulations of microvascular dissections and anastomoses may be more intricate, but the basic concept of performing delicate procedures while looking down a tube is "old hat" to us. The new techniques discussed here may extend the range of operative solutions to difficult clinical problems in urology perhaps as transurethral resection did in the thirties and forties.
