Long-term Patient-reported Clinical Outcomes and Reoperation Rate after Photovaporization with the XPS-180W GreenLight Laser.

OBJECTIVE: To evaluate the long-term reported clinical outcomes after photovaporization of the prostate (PVP) with the XPS-GreenLight laser in patients with symptomatic benign prostatic enlargement (BPE). DESIGN, SETTING, AND PARTICIPANTS: A prospective longitudinal study was performed for all consecutive patients with BPE who underwent PVP at our institution between 2010 and 2012. Patient-reported clinical outcomes were assessed at 1 mo, 3 mo, 12 mo, and 57 mo using International Prostate Symptoms Score, International Continence Society, and International Index of Erectile Function short-form questionnaires. Maximum flow rate (Qmax), postvoid residual urine measurements were assessed at 3 mo and 12 mo. Long-term satisfaction, complications, and reoperation rates were assessed by questionnaires. Prostate-specific antigen was measured at 3 mo, 12 mo, and 57 mo. INTERVENTION: A single surgeon (GF) has practiced photovaporization with a Moxy fiber, under transrectal ultrasonography monitoring. Long-term clinical outcomes were evaluated using questionnaires. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary measurement was the reoperation. RESULTS AND LIMITATIONS: Eighty-four patients of 102 answered the long-term questionnaire. The mean age was 68±7.2 yr. The mean follow-up was 57.4±6.8 mo. The mean prostate volume was 73±38ml. After treatment, the mean International Prostate Symptoms Score decreased significantly from 19.9±6.4 to 6.1±5.6, 3.9±3.4, and 5.9±5.8, respectively, at 3 mo, 12 mo, and 57 mo. The mean prostate-specific antigen level decreased significantly (-56%) from 4.5±4.3ng/ml preoperatively to 2.0±2.0ng/ml and 2.6±2.2ng/ml, respectively, at 12 mo and 57 mo. The mean Qmax increased from 9.6±3.8ml/s preoperatively to 23.9±11.5ml/s and 25.2±9.2ml/s, respectively, at 3 mo and 12 mo. Overall reoperation rate was 4.8%(4/84). Limitations include the single surgeon single center design study and the lack of long-term objectives data such as urodynamic parameters (postvoid residual urine and Qmax). CONCLUSIONS: Photovaporization of the prostate with the XPS-GreenLight laser is an effective technique able to durably improve reported clinical outcomes in patients with BPE. PATIENT SUMMARY: In this study we looked at the long-term outcomes after laser therapy with XPS-GreenLight laser for benign prostatic enlargement. We found a few reoperation rates and good stable reported clinical outcomes after a mean follow-up of 57 mo. We conclude that this laser technique can offer durably good reported clinical outcomes.

Robotic-assisted laparoscopic implantation of artificial urinary sphincter in women with intrinsic sphincter deficiency incontinence: initial results.

OBJECTIVE: To investigate the feasibility, safety, and functional results of robotic-assisted artificial urinary sphincter (R-AUS) laparoscopic implantation in women with stress urinary incontinence due to intrinsic sphincter deficiency. PATIENTS AND METHODS: Six women underwent an R-AUS implantation between 2012 and 2013. The mean age was 65 ± 9.6 years. Five patients had previous surgery for incontinence. The mean duration of follow-up was 14.3 months. A transperitoneal approach with a lateral positioning of the robotic arms was performed. The cuff implantation, positioning of the reservoir, and the pump were carried out similarly to the laparoscopic technique. Operative time, intraoperative occurrence of injuries of the bladder or vagina, postoperative complications, and continence (pad per day) were assessed. RESULTS: The R-AUS implantation was feasible in all cases without intraoperative injury and 1 grade 1 postoperative complication. Mean operative time, postoperative bladder catheterization, and hospitalization time were 210 ± 32 minutes, 7 days, and 6 days, respectively. At the end of the follow-up, 83% of cases were fully continent. CONCLUSION: R-AUS implantation in incontinent women with intrinsic sphincter deficiency was feasible and safe with good functional results. More data are needed before concluding to the superiority of this new technique compared with open or laparoscopic approaches.
