Robot-Assisted Laparoscopic Surgery for Vaginal Vault Prolapse Found to be Effective Alternative to Traditional Open Surgery

August 5th, 2006

ROCHESTER, Minn. — Mayo Clinic researchers have found that laparoscopic surgery assisted by a surgical robot to fix vaginal vault prolapse, a collapse of the vagina that can occur after a hysterectomy, is an effective option to the traditional, open surgical repair when measured at least a year after the surgery. Findings are published in the August issue of Journal of Urology.

In the United States, one out of nine women will undergo hysterectomy, a surgery to remove all or parts of the uterus. Ten percent of these will develop vaginal vault prolapse. “After hysterectomy, there’s a lack of support for the vagina as you remove the ligaments, and the vagina can fall down,” says Daniel Elliott, M.D., Mayo Clinic urologist and lead study investigator. “To imagine this, it helps to think of the vagina like a tube sock that’s inverted out. For some women, the vagina can come completely out — like three to five inches.

“This problem can be devastating both physically and socially,” he says. “Sometimes the patients can hardly walk.” The new laparoscopic surgery has advantages over the traditional repair, open sacrocolpopexy, according to Dr. Elliott.

These include:

  • Less overall recovery time
  • An overnight hospital stay only, rather than two to four days
  • Potentially lower risk of post-surgery bleeding
  • Markedly less pain, where 50 percent of patients go home taking only over-the-counter pain relievers
  • Women who may not tolerate the open procedure due to health issues may be candidates for this surgery

“My prediction is, with enough time and training, the robot-assisted, laparoscopic surgery will be the main procedure done in the future for women with major vaginal vault prolapse,” says Dr. Elliott.

The surgery is not widely available at present, due to the small number of surgeons trained in the procedure and the amount of equipment needed for surgeons to make the technique available. In order for the laparoscopic method to replace the standard repair, more surgeons need to be trained to perform it and researchers need more information about how durable and effective the repair is years after the surgery, according to Dr. Elliott.

To conduct this study, the researchers followed 30 patients undergoing robotic-assisted laparoscopic repair for post-hysterectomy vaginal vault prolapse. This technique involves a robot to speed up the process and to simplify its technically difficult aspects, such as the wrist strain involved in tying a large number of knots. The investigators analyzed the results of the surgery for 21 of the women who were 12 or more months post-surgery. The average follow-up time for the patients involved was 24 months, with a range of 12 to 26 months post-surgery. The average age was 67, with an age range of 47 to 83, and average time in surgery was 3.1 hours. All but one patient went home the day after surgery, and one left the hospital two days after surgery. All patients went home taking oral pain medications, and 10 indicated they only needed over-the-counter pain medications upon leaving the hospital. One patient experienced recurrence of her vaginal vault prolapse, and another developed a recurrent grade 3 rectocele, in which the rectum protrudes into the vagina. All patients indicated they were satisfied with the outcomes of their surgeries.

As duration of the repair is critical to its long-term success and patient satisfaction, according to Dr. Elliott, this study measured the results one year after the surgery. Patients in the study also will be assessed for success of the repair again at five years post-surgery in order to measure even longer duration of the repair.

Minimally-invasive urologic surgery using the daVinci Robotic Surgical System can effectively treat many urologic conditions, including prostate cancer, ureteropelvic junction obstruction (aka UPJ or Hydronephrosis), bladder cancer, ureteral cancers, kidney cancers, and vesicoureteral reflux.

Renal Cancer - Underutilization Of Partial Nephrectomy For Localized Renal Cell Carcinoma In The United States

June 29th, 2006

By Christopher G. Wood, MD

BERKELEY, CA (UroToday.com) - In the past, the gold standard for the treatment of localized renal tumors has been radical nephrectomy. Over time however, experience with nephron sparing surgery and, now, laparoscopic approaches have demonstrated oncologic equipoise and may provide for an improved quality of life for patients as compared to those undergoing radical nephrectomy for localized renal masses. The incidence of localized small renal tumors is increasing (3.8-5.6% annually) and one would predict that the incidence of nephron sparing approaches would increase in concert. Though more technically demanding than radical nephrectomy, nephron sparing offers the intuitive benefit of maximizing residual functioning renal tissue, while maintaining cancer control. A recent evaluation of the SEER database revealed that in 2001, 58% of patients with tumors < 2cm, and 80% of patients with tumors 2-4 cm were managed with radical nephrectomy. This study by Hollenbeck and colleagues suggests that while the use of nephron sparing approaches in the management of small renal masses has increased, it remains underutilized and very much regionalized to urban, teaching, high volume centers in the United States.

The authors used the Nationwide Inpatient Sample database to identify patients undergoing partial or radical nephrectomy in the United States during the period 1988-2002. The authors identified 66,621 patients who underwent either partial or radical nephrectomy during the study period, 7.5% of whom underwent partial nephrectomy. The authors noted that the frequency of partial nephrectomy increased during the study period from 3.7% in 1988 to 12.3% in 2002 (p< 0.001). Moreover the utilization rates for partial nephrectomy increased during the study period from 0.21/100,000 population in 1988 to 1.6/100,000 population in 2002 (p< 0.001). However, the authors noted that the utilization rates of radical nephrectomy also increased during the study period from 7.3/100,000 population in 1988 to 9.8/100,000 population in 2002 (p< 0.0001). Examining odds ratios (OR), patients were more likely to undergo partial nephrectomy at urban (OR 1.1), teaching (OR 1.3), high nephrectomy volume (defined as 28 nephrectomies/year) (OR 2.5) centers. Utilization of partial nephrectomy at such centers ranged from 33-52%.

This study further demonstrates the regionalization of specialized, technically demanding surgical procedures such as partial nephrectomy to major tertiary care teaching centers. It is alarming that despite the acceptance of partial nephrectomy as an oncologically viable procedure in anatomically receptive tumors, more than half of all tumors < 2cm and 80% of tumors 2 - 4cm in diameter are still managed with radical nephrectomy. The contribution of laparoscopic radical nephrectomy as an alternative to open partial nephrectomy has yet to be quantified and may further the underutilization of nephron sparing approaches.
