          There is a growing interest in achieving higher survival rates with the lowest morbidity in localized prostate cancer (PC) treatment. Consequently, minimally invasive techniques such as low-dose rate brachytherapy (BT) and robotic-assisted prostatectomy (RALP) have been developed and improved. Comparative analysis of functional outcomes and quality of life in a prospective series of 51BT and 42Da Vinci prostatectomies DV

          Materials and Methods

          Comparative analysis of functional outcomes and quality of life in a prospective series of 93 patients with low-risk localized PC diagnosed in 2011. 51patients underwent low-dose rate BT and the other 42 patients RALP. IIEF to assess erectile function, ICIQ to evaluate continence and SF36 test to quality of life wee employed.


          ICIQ at the first revision shows significant differences which favour the BT group, 79% present with continence or mild incontinence, whereas in the DV group 45% show these positive results. Differences disappear after 6 months, with 45 patients (89%) presenting with continence or mild incontinence in the BT group vs. 30 (71%) in the DV group. 65% of patients are potent in the first revision following BT and 39% following DV. Such differences are not significant and cannot be observed after 6 months. No significant differences were found in the comparative analysis of quality of life.


          ICIQ after surgery shows significant differences in favour of BT, which disappear after 6 months. Both procedures have a serious impact on erectile function, being even greater in the DV group. Differences between groups disappear after 6 months.

          Measurement of prostate-specific antigen in serum as a screening test for prostate cancer.

          Prostate-specific antigen (PSA) is secreted exclusively by prostatic epithelial cells, and its serum concentration is increased in men with prostatic disease, including cancer. We evaluated its usefulness in the detection and staging of prostate cancer. We measured serum PSA concentrations in 1653 healthy men 50 or more years old. Those with PSA values greater than or equal to 4.0 micrograms per liter then underwent rectal examination and prostatic ultrasonography. Ultrasound-directed prostatic needle biopsies were performed in the men with abnormal findings on rectal examination, ultrasonography, or both. The results were compared with those in 300 consecutively studied men 50 or more years old who underwent ultrasound-directed biopsy because of symptoms or abnormal findings on rectal examination. Serum PSA levels ranged from 4.0 to 9.9 micrograms per liter in 6.5 percent of the 1653 men (107). Nineteen of the 85 men in this group (22 percent) who had prostatic biopsies had prostate cancer. Serum PSA levels were 10.0 micrograms per liter or higher in 1.8 percent of the 1653 men (30). Eighteen of the 27 men in this group (67 percent) who had prostatic biopsies had cancer. If rectal examination alone had been used to screen the men who had biopsies, 12 of the 37 cancers (32 percent) would have been missed. If ultrasonography alone had been used to screen these men, 16 of the 37 cancers (43 percent) would have been missed. Serum PSA measurement had the lowest error rate of the tests, and PSA measurement plus rectal examination had the lowest error rate of the two-test combinations. The combination of measurement of the serum PSA concentration and rectal examination, with ultrasonography performed in patients with abnormal findings, provides a better method of detecting prostate cancer than rectal examination alone.

            Vattikuti Institute prostatectomy: contemporary technique and analysis of results.

            Contemporary techniques of radical prostatectomy achieve excellent oncologic outcomes; erectile dysfunction is the most common adverse effect. We have modified our technique of robotic radical prostatectomy (Vattikuti Institute prostatectomy [VIP]) in an attempt to minimize decrease of erectile function while maintaining the excellent oncologic outcomes achieved by the radical retropubic prostatectomy. We present our current technique of VIP with preservation of the lateral prostatic fascia ("veil of Aphrodite"). A total of 2652 patients with localized carcinoma prostate underwent VIP. The salient features of our current technique are early transection of the bladder neck, preservation of the prostatic fascia, and control of the dorsal vein complex after dissection of the prostatic apex. Oncologic and functional outcomes were obtained through a questionnaire collected by a third party not involved in patient care. Complete follow-up information was obtained in 1142 patients with a minimum follow-up of 12 mo (range: 12-66 mo; median: 36 mo). The actuarial 5-yr biochemical recurrence rate was 8.4% and the actual biochemical recurrence rate was 2.3%. Median duration of incontinence was 4 wk; 0.8% patients had total incontinence at 12 mo. The intercourse rate was 93% in men with no preoperative erectile dysfunction undergoing veil nerve-sparing surgery, although only 51% returned to baseline function. VIP with veil nerve sparing offers oncologic and continence results that are comparable to the results of conventional nerve-sparing radical prostatectomy. Early potency results are encouraging.

              Potency, continence and complication rates in 1,870 consecutive radical retropubic prostatectomies.

              We update results in a series of consecutive patients treated with anatomic radical retropubic prostatectomy regarding recovery of erections, urinary continence and postoperative complications. One surgeon performed anatomic radical retropubic prostatectomy on 1,870 men, using the nerve sparing modification when feasible. We evaluated recovery of erections and urinary continence in men followed for a minimum of 18 months. Patients who were not reliably potent before surgery, did not undergo a nerve sparing procedure, or received hormonal therapy or postoperative adjuvant radiotherapy were excluded from the analysis of potency rates but not of continence rates. Other postoperative complications were evaluated for the entire patient population. Recovery of erections occurred in 68% of preoperatively potent men treated with bilateral (543 of 798) and 47% treated with unilateral (28 of 60) nerve sparing surgery. Recovery of erections was more likely with bilateral than with unilateral nerve sparing surgery in patients less than 70 years old (71 versus 48%, p<0.001) compared with patients with age 70 years old or older (48 versus 40%, p = 0.6). Recovery of urinary continence occurred in 92% (1,223 of 1,325 men) and was associated with younger age (p<0.0001) but not with tumor stage (p = 0.2) or nerve sparing surgery (p = 0.3). Postoperative complications occurred in 10% of patients overall and were associated with older age (p<0.002) but the incidence declined significantly with increasing experience of the surgeon (p<0.0001). There was no operative mortality. Anatomic radical retropubic prostatectomy with the nerve sparing modification can be performed with favorable results in preserving potency and urinary continence. Better results are achieved in young men with organ confined cancer. Other complications can be reduced with increasing surgeon experience.
