From March 2010 to August 2011, 65 patients with localized prostate cancer （PCa） underwent bilateral intrafascial nerve-sparing extraperitoneal laparoscopic radical prostatectomy. These patients were matched in a 1.2 ratio to 130 patients with localized PCa who had undergone bilateral interfascial nerve-sparing extraperitoneal laparoscopic radical prostatectomy between January 2008 and August 2011. Operative data and oncological and functional results of both groups were compared. There was no difference in operative data, pathological stages and overall rates of positive surgical margins between the groups. There were 9 and 13 patients lost to follow-up in the intrafascial group and interfascial group, respectively. The intrafascial technique provided earlier recovery of continence at both 3 and 6 months than the interfascial technique. Equal results in terms of continence were found in both groups at 12 months. Better rates of potency at 6 months and 12 months were found in younger patients （age 65 years） and overall patients who had undergone the intrafascial nerve-sparing extraperitoneal laparoscopic radical prostatectomy. Biochemical progression-free survival rates I year postoperatively were similar in both groups. Using strict indications, compared with the interfascial nerve-sparing technique, the intrafascial technique provided similar operative outcomes and short-term oncological results, quicker recovery of continence and better potency. The intrafascial nerve-sparing technique is recommended as a preferred approach for young PCa patients who are clinical stages cT1 to cT2a and have normal preoperative potency.展开更多

This study includeda total of 103 consecutive sexually active Japanese men with localized prostate cancer undergoing nerve-sparing RP, and analyzed the postoperative EF, focusing on the significance of penile rehabilitation. In this series, 24 and 79 patients underwent bilateral and unilateral nerve-sparing RPs, respectively, and 10 or 20 mg of vardenafil was administered to 35 patients at least once weekly, who agreed to undergo penile rehabilitation. Twelve months after RP, 48 （46.6%） of the 103 patients were judged to have recovered EF sufficient for sexual intercourse without any assistance. The proportion of patients who recovered EF in those undergoing penile rehabilitation （60.0%） was significantly greater than that in those without penile rehabilitation （38.2%）. Of several parameters examined, the preoperative International Index of Erectile Function-5 （IIEF-5） score and nerve-sparing procedure were significantly associated with the postoperative EF recovery rates in patients with and without management by penile rehabilitation, respectively. Furthermore, univariate analysis identified the preoperative IIEF-5 score, nerve-sparing procedure and penile rehabilitation as significant predictors of EF recovery, among which the preoperative IIEF-5 score and nerve-sparing procedure appeared to be independently associated with EF recovery. Considering these findings, despite the lack of independent significance, penile rehabilitation with low-dose vardenafil could exert a beneficial effect on EF recovery in Japanese men following nerve-sparing RP.展开更多

The nerve-sparing Burch-Sling method represents a surgical advancement through the use of a nerve-sparing sling to treat genuine stress urinary incontinence. The procedure involves retropubic urethropexy using the FDA-approved Burch-Sling device. In this technique, the vagina is elevated bilaterally at the urethrovesical junction to the mid-urethra toward Cooper’s ligament above the base of the bladder. Then, the anterior vaginal wall and fascia are used as an endogenous suburethral sling without dissection. Two hundred twenty cases were included in this study;two hundred patients underwent the outpatient nerve-sparing sling method, and the other twenty underwent the novel abdominal Burch method. There were no major complications. The follow-up duration ranged from 6 months to eight years. All procedures were performed at the U.S. Women’s Institute at a 400-bed hospital in Fountain Valley, CA.展开更多
