Résumé

PURPOSE: The goal of this study was to evaluate changes in nocturia and other lower urinary tract symptoms (LUTS) after laparoscopic radical prostatectomy (LRP) and robot-assisted laparoscopic radical prostatectomy (RALP). MATERIALS AND METHODS: We reviewed the medical records of 96 patients who underwent LRP or RALP for clinically localized prostate cancer and completed the International Prostate Symptom Score (IPSS) questionnaire, which provided a basis for assessing their symptoms. We also evaluated maximal flow rate and post-void residual urine volume over a follow-up period of at least 24 months. We divided the patients into three groups according to postoperative changes in the frequency of nocturia. RESULTS: Voiding symptoms significantly improved over the course of 24 months in patients who underwent LRP or RALP. However, most patients showed persistent or increased nocturia after LRP or RALP. Moreover, more than one third of the patients (33/96) presented with exacerbated nocturia (1.0+/-0.9 episodes of preoperative nocturia vs. 3.0+/-1.3 episodes of postoperative nocturia). Multiple regression analysis showed that preoperative IPSS storage sub-score had negative association with the nocturia after radical prostatectomy (p=0.005). However, patients' age, body mass index, preoperative prostate specific antigen, Gleason score, T-stage, and prostate volume had no association. CONCLUSIONS: The present study showed that nocturia was influenced by a range of factors, including other storage LUTS and the relief of bladder outlet obstruction after radical prostatectomy. Moreover, the preoperative storage symptoms are regarded as an important factor which influences the changes of nocturia after radical prostatectomy.

Résumé

PURPOSE: To evaluate the combined role of mescenchymal stem cells (MSCs) infected with recombinant adenoviruses expressing human BDNF (rAd/hBDNF) on the erectile dysfunction in rat with cavernous nerve injury. MATERIALS AND METHODS: Rats divided into 4 groups: control group, bilateral cavernous nerve crushing group (BCNC group), BCNC with MSCs group and BCNC with MSCs infected with rAd/hBDNF group. After 4-week, functional assessment was done. PKH26 and BDNF staining of major pelvic ganglion and masson's trichrome staining of corpus cavernosum were performed. Western blot analysis of endothelial nitric oxide synthase (eNOS) and neuronal nitric oxide synthase (nNOS) was done in corpus cavernosum. RESULTS: After 4 weeks, BCNC with MSCs and MSCs infected with rAd/hBDNF groups showed significantly well-preserved erectile function compared with BCNC group. Moreover, the erectile function of MSCs infected with rAd/hBDNF group was significantly well-preserved than BCNC with MSCs group. The smooth muscle of corpus cavernosum was significantly preserved in BCNC with MSCs and MSCs infected with rAd/hBDNF groups compared with BCNC group. More preservation of smooth muscle was observed in rats with MSCs infected with rAd/hBDNF than with MSCs alone. Significant increase expression of eNOS and nNOS was noted in rats with MSCs infected with rAd/hBDNF than with MSCs alone. CONCLUSIONS: The erectile function was more preserved after injection with MSCs infected with rAd/hBDNF in rat with ED caused by cavernous nerve injury. Therefore, the use of MSC infected with rAd/hBDNF may have a better treatment effect on ED cause by cavernous nerve injury.
