Methods Twenty-one patients with prostate cancer had undergone radical prostatectomy during August 2001 to January 2010, in which two patients were operated through extraperitoneal laparoscope. Dorsal vein complex was sewed and ligated at early stage of surgery and prostate apex along with urethra were appropriately handled in all patients. By a serial measures consisting of protection for continence nerve and striated urethral sphincter, the function of urinary continence was managed to be spared in twenty-one patients, erectile function was managed to be spared through reservation of neurovascular bundle in seventeen patients (Bilateral neurovascular bundles were reserved in twelve patients, unilateral neurovascular bundle was reserved in five patients). Results All surgeries were successful without severe perioperative complications. The catheters were removed fourteen days after surgery in all patients, and it was observed that micturition was fluent in twenty-one patients. Functional recovery of urinary continence occurred within three months after surgery in six patients and twleve months in thirteen patients, continuous mild-moderate incontinece occurred in two patients. Erectile function was normal before surgery and neurovascular bundle was reserved during surgery in seventeen patients. The recovery of erectile function occurred within three months after surgery in two patients and twelve months in eight patients, erectile function was impaired in four patients, erectile dysfunction occurred in three patients, pathological diagnosis indicated prostate adenocarcinoma in all cases, while seminal vesicle and bladder neck were not invaded and bilateral pelvic lymph nodes were not metastasized, moreover, the pathological diagnosis of resected edge of posterior urethra was positive in one patient. One patient of bio-chemical recurrence occurred respectively within six months, twenty-four months and fifty-four months after surgery. Conclusion During radical prostatectomy for prostate cancer, delicately anatomizing and appropriate surgical technique could effectively protect erectile function and urinary continence and consequently achieve radical resection of tumor at the same time.
ObjectiveTo systematically review the association between 5α-reductase inhibitors (5ARIs) and risk of sexual dysfunction in subjects with benign prostatic hyperplasia (BPH).MethodsPubMed, Web of Science, The Cochrane Library, EMbase, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect studies on the association between 5ARIs and risk of sexual dysfunction in subjects with BPH from inception to October 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed by using Stata 12.0 software.ResultsA total of 15 studies involving 17 774 subjects were included. The results of the meta-analysis showed that compared with the placebo group, 5ARIs could significantly increase risk of erectile dysfunction (RR=1.52, 95%CI 1.36 to 1.69, P<0.000 1), while decrease libido (RR=1.79, 95%CI 1.37 to 2.32, P<0.000 1) and ejaculation disorder (RR=2.97, 95%CI 1.82 to 4.83, P<0.000 1) in subjects with BPH. Subgroup analysis of the type of 5ARIs, intervention period, publication year and sample size showed that the 5ARIs had a higher risk of sexual dysfunction than the placebo group.ConclusionsCurrent evidence shows that 5ARIs can increase risk of erectile dysfunction, decrease libido and ejaculation disorder in subjects with BPH. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusions.
摘要:目的: 随机对照研究、评估生物反馈训练治疗慢性功能性便秘的疗效。 方法 : 60例慢性功能性便秘患者,随机分为治疗组30例和对照组30例。治疗组接受1个疗程(5周)生物反馈训练治疗(10次为一个疗程、一次30～45分钟、每周2次)。对照组患者接受聚乙二醇4000 10g BID 口服,疗程5周。治疗前后作便秘症状评分、结肠通过试验检测、直肠肛门压力检测。 结果 : 生物反馈训练和聚乙二醇4000均可使多数慢性功能性便秘患者的大便次数、大便性状及伴随症状恢复正常或缓解,总有效率分别为667%和80%(P ＞005)。生物反馈训练和聚乙二醇4000口服治疗后,结肠通过试验72小时标志物排出率分别为75%及73%,均较治疗前明显增加。生物反馈训练治疗后力排时肛门压明显下降。 结论 : 生物反馈训练对出口梗阻型、慢传输型便秘均有效,是一种有效的、新兴的治疗慢性功能性便秘的方法,可作为功能性便秘的一线治疗方法。Abstract: Objective: To assess the clinic effect of biofeedback therapy for functional constipation. Methods : Sixty cases of chronic functional constipation were randomly divided into treatment group (30 cases) and control group (30 cases). Cases in the treatment group were exposed to biofeedback for a fiveweeklong treatment course—individual treatment lasted for 3045 minutes and twice per week. Patients in the control group received PEG 4000 10g BID for five weeks. Data from constipation symptom score, colonic transit test, and anorectal manometry were done and compared before and after two kinds of treatments. Results : Biofeedback training and PEG 4000 could restore the stoolfrequency, stool characteristics and accompanying symptoms to normal or mitigation of the majority of patients with chronic functional constipation, with the total effective rates being 667% and 80% (P gt;005), respectively. After biofeedback training and PGE 4000 treatment, the discharge rate of 72hour markers of colonic transit test significantly increased to 75% and 73%, respectively. Additionally, anorectal pressure decreased dramatically after biofeedback training. Conclusion : Biofeedback training would play a positive role in outlet obstruction and slow transit constipation. Thus, it could be an effective firstline treatment of chronic functional constipation.
Objective To study the relationship between autonomic nerve preservation and sexual and urinary functions after total mesorectal excision in patients with cancer of the lower rectum, and to explore improved nursing methods for these patients. Methods Eligible patients with cancer of the lower rectum were non-randomly assigned to either a control group (n=278)or an autonomic nerve-preserving group （n=263）. The recovery time of micturition desire, catherization time, lower urinary tract infection rate, residual urine, severity of urinary disorders and sexual disorders were observed. Results The recovery time of micturition desire, catherization time, lower urinary tract infection rate, residual urine, severity of urinary disorders and sexual disorders were lower in the autonomic nerve-preserving group than in the control group. (Plt;0.05) . Conclusion Autonomic nerve preservation radical resection leads to better maintenance of urinary and sexual functions for patients with cancer of the lower rectum. Nursing should be focused on the prevention of urinary tract complications and the rehabilitation of sexual and urinary functions.
ObjectiveTo analyse baseline information, semen, sex hormones and sexual function to understand the differences between male patient with epilepsy(MPWE) and healthy men. At the same time, we preliminarily evaluated the risk factors related to reproductive function in MPWE to provide clinical method for reducing the risk of infertility.MethodsWe collected data of 112 MPWE in the Department of Neurology, First Affiliated Hospital of Dali University from February 2019 to February 2020. Sixty-seven healthy male volunteers matching the age of the survey group were selected. All men completed semen and sex hormone test. Men with sexual life experience completed the International index of erectile function scale (IIEF-5) and the Premature ejaculation diagnostic tool (PEDT). MPWE completed the Quality of life in epilepsy-1(QOLIE-31). The baseline data, semen quality, sex hormone level and sexual function questionnaire scores of MPWE and healthy controls were compared. In addition, according to the diagnostic criteria of abnormal male reproductive function, MPWE were divided into abnormal group and normal group. Single factor analysis and binary logistic regression analysis were used to preliminarily explore the related risk factors of reproductive function in MPWE.ResultsCompared with the healthy control group, the proportion of married and childbearing, testosterone level, sperm concentration, sperm survival rate and IIEF-5 score in MPWE were significantly reduced (P<0.05). Compared with the normal group, age, body mass index, seizure frequency and drug type in the abnormal group were significant differences statistically (P<0.05). The total score and energy score of QOLIE-31 in the abnormal group were significantly lower than that in the normal group (P<0.05). Binary Logistic regression analysis indicated that energy score [B=−0.033, OR=0.967, 95%CI(0.937, 0.999)], age [B=0.879, OR=2.408, 95%CI (1.070, 5.416)], seizure frequency [B=1.788, OR=5.976, 95% CI (2.031, 17.589)].ConclusionThe reproductive function of MPWE is lower than that in healthy men. The total score, energy score, age, body mass index, seizure frequency and type of drugs will significantly affect the reproductive function of MPWE. Energy score, age and seizure frequency are independent risk factors that affect the reproductive function of MPWE. Abnormal reproductive function of MPWE was positively correlated with age and seizure frequency, but negatively correlated with energy score.
Objective To investigate the influence of Lamotrigine (LTG) on sex hormone, seminal fluid and sexual function in male epilepsy patients. Methods The blood sex hormone levels and sperm quality were detected in 20 normal controls and 16 male epilepsy patients in Epilepsy Center of Sichuan Province People's Hospital from April 2015 to November 2016. All participants were detected before taking medicine and after being treated with LTG monotherapy for 1 year. The international index of erectile function-5 (IIEF-5) was employed to assess the sexual function in the groups above, and the results were compared. Results Compared with the control group, the total number of sperm, the rate of forward movement, survival, normal sperm and the score of IIEF-5 in the untreated group were less (P<0.05). LTG treatment group's sperm parameters and the score of IIEF-5 seemed improve, but there was no statistically significant difference (P>0.05). There was no significant difference in sexual hormones between the groups above (P>0.05). Conclusions Semen quality and the score of IIEF-5 in epileptic male decline more easily; LTG might improve the semen quality and sexual function, but no significant difference has being found.

Objective To systematically review the effect of bariatric surgery for male’s erectile function. Methods We electronically searched databases including PubMed, EMbase, The Cochrane Library (Issue 5, 2016), CNKI, VIP and WanFang Data from inception to May 30th 2016, to collect randomized controlled trials and before-after studies about bariatric surgery therapies for erectile function in obese male. Two reviewers independently screened literature, extracted data, and assessed the methodological quality of included studies. Then RevMan 5.3 software was used for meta-analysis. Results A total of 7 before-after studies involving 270 patients were included. The results of meta-analysis showed that: compared with before treatment, bariatric surgery could significantly improve 1-year erectile function score (MD=5.05, 95%CI 3.52 to 6.59, P < 0.000 01), 1-year sexual desire score (MD=0.99, 95%CI 0.47 to 1.51, P=0.000 2), 1-year contact satisfaction score (MD=2.70, 95%CI 0.21 to 5.19, P=0.004) and 1-year total satisfaction score (MD=1.68, 95%CI 0.27 to 3.09, P=0.002), but there was no significant difference in orgasm function score (MD= –0.21, 95%CI –0.74 to 0.33, P=0.45) between before and after treatment. Conclusion Bariatric surgery is effective in improving the erectile function, sexual desire and sexual satisfaction in morbidly obese male. Due to the limited quality and quantity of the included studies, the above conclusion needs to be verified by more large-scale high-quality studies.
