[Clinical experience of total prostatectomy using DDV-L (deep dorsal venous ligator]

We evaluated blood loss in operation and postoperative urinary incontinence to total prostatectomy using the DDV-L.

We performed total retropubic prostatectomy for 38 patients from May 1979 to May 1995. In 14 patients from October 1994 to May 1995 the DDV-L was used. The DDV-L is used in transurethral approach, disposable device to ligate the deep dorsal vein complex by delivering the needle to lateral of deep dorsal vein complex.

We composed the 14 patients which was used the DDV-L with the 14 patients which was from April 1990 to July 1994 was not used that. The mean operating time of 14 patients which was used the DDV-L was 178.5 min, 14 patients which was not used that was 188.0 min. The mean blood loss of 14 patients which was used th DDV-L was 735.7 ml, 14 patients which was not used that was 1250.2 ml. We transfused blood into 2 of 14 patients which was used the DDV-L (14.0%), 10 of 14 patients which was not used that (71.4%). The one of 14 patients which was used the DDV-L (7.5%) and 5 of 14 patients which was not used that (35.7%) had postoperative urinary incontinence needing pad.

Accordingly the operating results of 14 patients which was used the DDV-L was undoubtedly better that of 14 patients which was as regards blood loss in operation, postoperative urinary incontinence. We can perform easily the management of deep dorsal vein complex by DDV-L, so we can cut of urethra without excess hemostasis and electronic coagulation, and leave enough long membranous urethra. We consider the DDV-L is helpful to total prostatectomy.
