          Vattikuti Institute prostatectomy, a technique of robotic radical prostatectomy for management of localized carcinoma of the prostate: experience of over 1100 cases.

          Advances in surgical techniques, technology, and surgeons' skills have allowed robot-assisted radical prostatectomy to be an option in the management of organ-confined prostate cancer. The goals of the VIP technique are to cure cancer, preserve urinary continence, preserve potency, and decrease morbidity, along with the benefits of a minimally invasive surgery and excellent cosmesis. VIP is nearly equal to traditional retro-pubic prostatectomy, with certain outstanding advantages.

            Laparoscopic versus open radical prostatectomy: a comparative study at a single institution.

            There is an ongoing debate about the benefits of laparoscopic radical prostatectomy compared to the open retropubic approach. We compared the last 219 patients treated with open retropubic prostatectomy with 438 patients treated with laparoscopic radical prostatectomy at our institution, focusing on operative data, complications and mid-term outcome. From December 1994 to November 1999 a total of 219 patients were treated with open prostatectomy and pelvic lymph node dissection (group 1). From March 1999 to September 2002, 219 patients underwent early (group 2) and 219 underwent late (group 3) laparoscopic radical prostatectomy and pelvic lymph node dissection. The same surgeons performed both operations. All 3 groups were similar with respect to mean patient age, mean prostate specific antigen value, median Gleason score, previous transurethral resection of the prostate and neoadjuvant treatment, although there was a slight stage shift in favor of the 2 laparoscopic groups. Mean operating time was significantly shorter after open surgery (196 minutes) compared to the early laparoscopic group (288) but it did not differ significantly from the late laparoscopic group (218). Mean blood loss (1,550 versus 1,100 versus 800 cc) and transfusion rates (55.7% versus 30.1% versus 9.6%) in groups 1 to 3 favored the laparoscopic groups. The complication rate in groups 1 to 3 was lower for laparoscopy (19.2% versus 13.7% versus 6.4%), but the spectrum differed. The early laparoscopic group had a higher incidence of rectal injuries (1.8% versus 3.2% versus 1.4% in groups 1 to 3, respectively) and urinary leakage (0.5% versus 2.3% versus 0.9%), whereas more lymphoceles (6.9% versus 0% versus 0%), wound infection (2.3% versus 0.5% versus 0%), embolism/pneumonia (2.3% versus 0.5% versus 0.5%) and anastomotic strictures (15.9% versus 6.4% versus 4.1%) occurred after open surgery. The amount of postoperative analgesia was significantly greater after open surgery (50.8 versus 33.8 versus 30.1 mg. in groups 1 to 3, respectively). Median catheter time was longer after open retropubic prostatectomy (12 versus 7 versus 7 days in groups 1 to 3, respectively) but the continence rates were similar in all 3 groups at 12 months (89.9% versus 90.3% versus 91.7%). The rate of positive margins did not differ significantly in groups 1 to 3 (28.2% versus 21.0% versus 23.2%), prostate specific antigen recurrence was equivalent related to the different observation periods. Laparoscopic radical prostatectomy is technically demanding, with an initially longer operative time, higher incidence of rectal injuries and urinary leakage. The overall outcome after 219 cases favors the laparoscopic approach. Consequently, at our institution laparoscopic radical prostatectomy has become the method of choice.

              Urinary tract injuries after hysterectomy.

              To evaluate the nationwide incidence and characteristics of urinary tract injuries after laparoscopic hysterectomy, total abdominal hysterectomy, supracervical abdominal hysterectomy, and vaginal hysterectomy. We analyzed retrospectively 142 urinary tract injuries after hysterectomy, reported to the National Patient Insurance Association in Finland from 1990 through 1995. The Finnish Hospital Discharge Register collects data on procedures from all hospitals, and 62,379 hysterectomies were carried out during the study period. The total incidence of ureteral injury after all hysterectomies was 1.0 of 1000 procedures: 13.9 of 1000 after laparoscopic, 0.4 of 1000 after total abdominal, 0.3 of 1000 after supracervical abdominal, and 0.2 of 1000 after vaginal hysterectomy. Difficulties during an operation with a ureteral injury were encountered in 51%, 76%, 100%, and 100%; the failure rates of primary repair of a ureteral injury were 5%, 12%, 0%, and 0%; and the convalescence times after a ureteral injury were 86 days, 94 days, 71 days, and 47 days after laparoscopic, abdominal, supracervical abdominal, and vaginal hysterectomies, respectively. The incidence of bladder injury was 1.3 of 1000 procedures. Sixty-five percent of reported bladder injuries were fistulas, giving an incidence of vesicovaginal fistula of 0.8 of 1000 procedures after all hysterectomies: 2.2 of 1000 after laparoscopic, 1.0 of 1000 after total abdominal, 0 of 1000 after supracervical abdominal, and 0.2 of 1000 after vaginal hysterectomy. Difficulties during an operation with a bladder injury were encountered in 53%, 37%, 100%, and 0%; the failure rates of primary repair of a simple bladder injury were 5%, 18%, 0%, and 0%; the failure rates of primary repair of a vesicovaginal fistula were 17%, 20%, 0%, and 0%; and the convalescence times after a bladder injury were 51 days, 118 days, 71 days, and 99 days after laparoscopic, abdominal, supracervical abdominal, and vaginal hysterectomy, respectively. The risk of ureteral injury is higher after laparoscopic hysterectomy compared with traditional hysterectomies.
