OBJECTIVE: To investigate the efficacy and safety of the Adjustable Transobturator Male System (ATOMS) in men with stress urinary incontinence after transurethral resection of the prostate (TURP). MATERIALS AND METHODS: From a large international prospectively administrated ATOMS register, we identified 49 patients with an ATOMS device as a result of persistent stress urinary incontinence after TURP. For evaluation, the men were divided into standard transurethral resection of the prostate (sTURP) and palliative transurethral resection of the prostate (pTURP) in radiated patients. Baseline and follow-up measurements included continence parameters, urodynamics, quality-of-life surveys (Patient Global Impression-Improvement and International Consultation on Incontinence Questionnaire-Short Form), and pain ratings. The dry rate (0-1 security pad/<10 mL urine loss), the success rate (overall improvement), removals, complications, and treatment failures were recorded. A P value of <.05 was considered statistically significant. RESULTS: After a median of 34 and 22 months' follow-up and 2-3 adjustments, the sTURP and pTURP cohorts had 58% and 50% dry rates and 90% and 87% success rates. Hence, no improvement was seen in 10% and 13%. The removal rate was higher in pTURP (50% vs 10%, P = .0171) and infection was the most common side effect (50%) observed. Neither intraoperative nor Clavien-Dindo 4 and 5 adverse events were recorded. In sTURP and pTURP, the median daily pad count and the pad test improved significantly (all P <.001), and quality-of-life parameters shifted to a high satisfaction level (P <.001 and P = .001). Urodynamics remained unchanged and postoperative pain was not an issue. CONCLUSION: The ATOMS device shows promising treatment outcomes in patients after TURP and a similar efficacy as in postprostatectomy incontinence. There is no difference in continence outcome between sTURP and pTURP; however, a higher removal rate was found after pTURP, which may be important for patient counseling.

Due to the urgent need for new prostate cancer (PCa) therapies, the role of androgen receptor (AR)-interacting proteins should be investigated. In this study we aimed to address whether the AR coactivator nuclear receptor coactivator 1 (NCOA1) is involved in PCa progression. Therefore, we tested the effect of long-term NCOA1 knockdown on processes relevant to metastasis formation. [(3)H]-thymidine incorporation assays revealed a reduced proliferation rate in AR-positive MDA PCa 2b and LNCaP cells upon knockdown of NCOA1, whereas AR-negative PC3 cells were not affected. Furthermore, Boyden chamber assays showed a strong decrease in migration and invasion upon NCOA1 knockdown, independently of the cell line's AR status. In order to understand the mechanistic reasons for these changes, transcriptome analysis using cDNA microarrays was performed. Protein kinase D1 (PRKD1) was found to be prominently up-regulated by NCOA1 knockdown in MDA PCa 2b, but not in PC3 cells. Inhibition of PRKD1 reverted the reduced migratory potential caused by NCOA1 knockdown. Furthermore, PRKD1 was negatively regulated by AR. Immunohistochemical staining of PCa patient samples revealed a strong increase in NCOA1 expression in primary tumors compared with normal prostate tissue, while no final conclusion could be drawn for PRKD1 expression in tumor specimens. Thus, our findings directly associate the AR/NCOA1 complex with PRKD1 regulation and cellular migration and support the concept of therapeutic inhibition of NCOA1 in PCa.
