ABSTRACT

OBJECTIVE@#To evaluate urinary continence recovery time and risk factors of urinary continence recovery after robot-assisted laparoscopic radical prostatectomy (RARP).@*METHODS@#From January 2019 to January 2021, a consecutive series of patients with localized prostate cancer (cT1-T3, cN0, cM0) were prospectively collected. RARP with total anatomical reconstruction was performed in all the cases by an experienced surgeon. Lymph node dissection was performed if the patient was in high-risk group according to the D'Amico risk classification. The primary endpoint was urinary continence recovery time after catheter removal. Postoperative and pathological variables were analyzed. Continence was rigo-rously analyzed 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks after catheter removal. Continence was evaluated by recording diaper pads used per day, and all the patients were instructed to perform the 24-hour pad weight test until full recovery of urinary continence. The patient was defined as continent if no more than one safety pad were needed per day, or no more than 20-gram urine leakage on the 24-hour pad weight test. Time from catheter removal to full recovery of urinary continence was recorded, and risk factors influencing continence recovery time evaluated.@*RESULTS@#In total, 166 patients were analyzed. The mean age of the enrolled patients was 66.2 years, and the median prostate specific antigen (PSA) was 8.51 μg/L. A total of 59 patients (35.5%) had bilateral lymphatic dissection, and 28 (16.9%) underwent neurovascular bundle (NVB) preservation surgery. Postoperative pathology results showed that stage pT1 in 1 case (0.6%), stage pT2 in 77 cases (46.4%), stage pT3 in 86 cases (51.8%), and positive margins in 28 patients (16.9%). Among patients who underwent lymph node dissection, lymph node metastasis was found in 7 cases (11.9%). Median continence recovery time was one week. The number of the continent patients at the end of 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks were 65 (39.2%), 32 (19.3%), 34 (20.5%), 24 (14.5%), and 9 (5.4%). Two patients remained incontinent 24 weeks after catheter removal. The continence rates after catheter removal at the end of 48 hours, 1 week, 4 weeks, 12 weeks, and 24 weeks were 39.2%, 58.4%, 78.9%, 93.4%, and 98.8%, respectively. Univariate COX analysis revealed that diabetes appeared to influence continence recovery time (OR=1.589, 95%CI: 1.025-2.462, P=0.038). At the end of 48 hours, 4 weeks, 12 weeks, and 24 weeks after catheter removal, the mean OABSS score of the continent group was significantly lower than that of the incontinent group.@*CONCLUSION@#RARP showed promising results in the recovery of urinary continence. Diabetes was a risk factor influencing continence recovery time. Bladder overactive symptoms play an important role in the recovery of continence after RARP.

ABSTRACT

OBJECTIVE@#To analyze the prognostic factors affecting the failure of transvaginal repair of vesicovaginal fistula (VVF).@*METHODS@#A retrospective nested case-control study was conducted. A total of 15 patients who underwent unsuccessful transvaginal vesicovaginal fistula repair in the Department of Urology, Peking University First Hospital from January 2014 to December 2020 were enrolled as the case group. A total of 60 patients receiving transvaginal vesicovaginal fistula repair by the same surgeon within the same time range, were selected as the control group. The age, body mass index (BMI), etiology of vesicovaginal fistula, associated genitourinary malformation, frequency of repair, characteristics of fistula, surgical procedure, postoperative recovery and other factors were compared between the case group and the control group, and the influencing factors of failure were analyzed.@*RESULTS@#The BMI of the case group was (26.3±3.9) kg/m2, the diameter of vaginal fistula was (1.5±0.8) cm, and the operative time of transvaginal repair was (111.8±19.8) min. The proportion of the patients with genitourinary malformations was 4/15, the proportion of the patients with multiple vaginal repairs was 13/15, the proportion of the patients with concurrent ureteral reimplantation was 6/15, and the proportion of the patients with postoperative fever was 5/15. In the control group, the BMI was (23.9±3.0) kg/m2, the diameter of vaginal fistula was (0.8±0.5) cm, the operative time of transvaginal repair was (99.9±19.7) min, the rate of associated genitourinary malformation was 2/60, the rate of multiple transvaginal repair was 18/60, the rate of concurrent ureteral reimplantation was 5/60, and no postoperative fever was found. Compared with the control group, the case group had higher BMI (P=0.013), bigger vaginal fistula (P=0.002), longer time of operation (P=0.027), higher proportion of genitourinary malformations (P=0.013), higher proportion of repeated transvaginal repair (P < 0.001), higher proportion of ureter reimplantation (P=0.006), and higher proportion of postoperative fever (P < 0.001). Multivariate analysis showed that fistula diameter ≥1 cm (OR=10.45, 95%CI=1.90-57.56, P=0.007) and repeated transvaginal repair (OR=16.97, 95%CI=3.17-90.91, P=0.001) were independent prognostic factors for VVF failure in transvaginal repair.@*CONCLUSION@#Fistula diameter ≥1 cm and repeated transvaginal repair are independent prognostic factors of failure in transvaginal repair.

ABSTRACT

Purpose To study the expression and the clinical significance of β3GnT8,MMP-2,PCNA in gastric cancer tissue. Methods The histological chips of paraffin specimens of gastric cancer were prepared,and immunohistochemical methods were used to detect the expression of β3GnT8,MMP-2 and PCNA in gastric cancer and adjacent tissue. Results The expression of β3GnT8 and MMP-2,PCNA in gastric cancer was higher than that in adjacent tissue (P = 0. 001) . The expression of β3GnT8 and MMP-2 was significantly positively correlated with the clinical stage (P = 0. 001) ,depth of invasion (P = 0. 011) and lymph node metastasis (P = 0. 003) of gastric cancer. The expression of β3GnT8 was significantly positively correlated with that of MMP-2 (r = 0. 703,P = 0. 001) and PCNA (r = 0. 231,P = 0. 024) . The overall survival time of the β3GnT8 positive expression group was significantly shorter than that of the negative expression group(χ2 = 3. 957,P = 0. 047) . Conclusion The expression of β3GnT8 is increased in gastric cancer. β3GnT8 can promote the invasion and metastasis of gastric cancer and is associated with poor prognosis in patients with gastric cancer.

ABSTRACT

OBJECTIVE@#To explore risk factors of urinary incontinence (UI) and influences of UI on quality of life in female medical staff from Beijing.@*METHODS@#One hundred and forty-six female medical personnel were included in the present study through the convenient sampling method in Peking University First Hospital. The questionnaires contained the following information: demographic information, daily urination condition, the severity of UI [international consultation on incontinence questionnaire short form (ICI-Q-SF)], and the influences of UI on quality of life (QOL). We excluded the subjects who were in pregnancy or had urinary infection, neurogenic bladder, or urethral stricture. We used SPSS 21.0 software (IBM Corp, Armonk, NY) for statistical analysis. The Kolmogorov-Smirnov test determined the normality of the continuous variables. Means and standard deviation presented continuous variables in normality. Median and range presented continuous variables without normality. Frequency and percentile were used to present categorical or ranked variables.@*RESULTS@#There were 63 out of 146 (43.2%) female medical staff suffering from UI. The mean age and body mass index of the whole study cohort were (39.4±9.9) years and (22.3±3.4) kg/m2. The median delivery times of all the subjects were 1 time (range: 0-3 times). Fifty out of 146 (34.2%) subjects had transvaginal delivery history. Chronic constipation was diagnosed in 32 subjects (21.9%). No significant difference in daytime micturition and nocturia times were found between the UI and non-UI subjects. According to the multivariate analysis, chronic constipation (OR=4.95, 95%CI=1.81-13.53, P=0.002) and transvaginal delivery history (OR=3.50, 95%CI=1.49-8.21, P=0.004) were independent risk factors for UI. The non-UI subjects had superior quality of life than the UI subjects in terms of incontinence quality of life (I-QOL) total scores and all sub-scores of avoidance and limiting behaviors, psychosocial impacts, and social embarrassment (P<0.001). In addition, avoidance and limiting behaviors (r=-0.449, P<0.001), psychosocial impacts (r=-0.538, P<0.001), and social embarrassment (r=-0.454, P<0.001) of the 63 UI subjects were equally influenced by the incontinence symptom.@*CONCLUSION@#UI is not uncommon in female medical staff. The quality of life of medical faculty is influenced by UI in terms of avoidance and limiting behaviors, psychosocial impacts, and social embarrassment. Chronic constipation and transvaginal delivery history were independent risk factors for UI.

ABSTRACT

We aim to reassess the safety of the monopolar transurethral resection of the prostate (M-TURP) without suprapubic cystostomy at our institution over the past decade. This retrospective study was conducted in patients who underwent M-TURP at Peking University First Hospital between 2003 and 2013. A total of 1680 patients who had undergone M-TURP were identified, including 539 patients in the noncystostomy group and 1141 patients in the cystostomy group. After propensity score matching, the number of patients in each group was 456. Smaller reductions in hemoglobin and hematocrit (10.9 g vs 17.6 g and 3.6% vs 4.7%, respectively) were found in the noncystostomy group. In addition, patients undergoing surgery without cystostomy had their catheters removed earlier (4.6 days vs 5.2 days), required shorter postoperative stays in the hospital (5.1 days vs 6.0 days), and were at lower risk of operative complications (5.7% vs 9.2%), especially bleeding requiring blood transfusion (2.9% vs 6.1%). Similar findings were observed in cohorts of prostates of 30-80 ml and prostates >80 ml. Furthermore, among patients with a resection weight >42.5 g or surgical time >90 min, or even propensity-matched patients based on surgical time, those with cystostomy seemed to be at a higher risk of operative complications. These results suggest that M-TURP without suprapubic cystostomy is a safe and effective method, even among patients with larger prostates, heavier estimated resection weights, and longer surgical times.

ABSTRACT

<p><b>OBJECTIVE</b>To determine the distribution characteristics of cancerous foci in the prostate by retrospective analysis on the radical prostatectomy (RP) samples from patients with prostate cancer diagnosed by single positive core biopsy and treated by RP.</p><p><b>METHODS</b>Thirty-seven patients with prostate cancer diagnosed by ultrasound-guided biopsy and single positive core biopsy underwent RP. We reviewed the pre- and post-operative data of the patients, compared the results of biopsies and pathological examination of the RP samples, and analyzed the factors that led to the underestimation of the overall prostate cancer risks.</p><p><b>RESULTS</b>Post-operative pathological results showed multifocal distribution of the tumors in 70% of the patients (26/37) and obviously increased Gleason score (7-9) in 56% (21/37). The clinical stages of the tumors had been significantly underestimated preoperatively. The underestimation of their clinical stages might be due to a larger proportion of cancer tissues in a single positive core biopsy, and that of the overall cancer risks attributed to PSAD > 0.2 microg/L. Larger prostate volume (> or = 40 ml) increased the possibility of multifocal distribution.</p><p><b>CONCLUSION</b>The risk of prostate cancer diagnosed by single positive core biopsy might be underestimated, and the cancerous foci were characterized by multifocal distribution in the prostate.</p>

ABSTRACT

<p><b>BACKGROUND</b>Despite 100 years of research, the continued absence of well-established risk factors impedes the diagnosis and treatment of interstitial cystitis/painful bladder syndrome (IC/PBS). We aimed to identify risk factors in patients with lower urinary tract symptoms (LUTS) without urinary tract infection or benign prostate hyperplasia in China.</p><p><b>METHODS</b>A total of 397 outpatients with LUTS presenting for care to urology clinics in several hospitals throughout China were surveyed using a standardized questionnaire and validated outcome measures. The definitions for painful bladder syndrome based on the O'Leary-Sant interstitial cystitis symptom and problem indices were used. The prevalence of possible risk factors was analyzed using the Fisher's exact test and Pearson chi-square test, and multivariate predictive models were developed using binary Logistic regression methods.</p><p><b>RESULTS</b>Of those multi-centre patients surveyed, including 174 women and 223 men, 41% (162/397) met criteria for painful bladder syndrome. There was a significant difference between women and men (55% (95/174) vs. 30% (67/223), P < 0.001). Women with IC/PBS were more likely than those without IC/PBS to report a history of gynecological infections (odds ratio (OR): 2.85; 95% confidence interval (CI): 1.32 - 6.16, P = 0.007), intake of stimulatory foods (OR: 3.52; 95%CI: 1.50 - 8.30; P = 0.004), irritable bowel (OR: 3.46; 95%CI: 1.22 - 9.80; P = 0.014) and/or anorectal disease (OR: 2.68; 95%CI: 1.12 - 6.40, P = 0.023). After adjusting for confounding factors, bladder pain was significantly associated with stimulatory foods (OR: 3.85; 95%CI: 1.58 - 9.36, P = 0.003) and anorectal disease (OR: 2.76; 95%CI: 1.09 - 7.04, P = 0.03) in women. Caffeine beverage intake (OR: 3.54; 95%CI: 1.54 - 8.12, P = 0.003) was identified the only modifiable association noted in multivariate analysis of men.</p><p><b>CONCLUSIONS</b>We found that stimulatory foods, anorectal disease and caffeine beverages are potential risk factors for IC/PBS. Further studies are necessary to determine their role in the pathogenesis of this disorder.</p>

ABSTRACT

Objective To analyze the genetic characteristics of HIV-1 CRF01_AE strains prevailing in. the four provinces of southern China. Methods Plasma samples were collected from the newly diagnosed HIV-1 individuals reported in 2006 in Guangdong, Guangxi, Jiangxi and Hunan province. The gag and env gene fragments were amplified from RNA template extracted from plasma using RT and nested PCR methods. CRF01_AE sequences were analyzed by phylogcnetie methods and characterized by calculating the genetic distance and Entropy analysis. Results Two main epidemic clusters were found to exist in the CRF01 AE strains from 210 HIV-1 CRF01 AE infected individuals collected in the 4 provinces, southern China. It was found that no international reference strain was closely correlated with cluster Ⅰ , which including 123 samples. The strains in cluster Ⅱ, consisting 57 cases of samples, were closely related with the strains identified in Vietnam. Genetic distance analysis of gag and env genes showed that the diversity of cluster Ⅰ was obviously less than that of cluster Ⅱ. Data on nucleotide polymorphism showed that nucleotides compositions of 42 sites in gag and 40 sites in env wer esignificantly different between the two clusters. When compared with cluster Ⅱ , the polymorphism decreased at 61 nucleotide sites but increased at 21 sites in cluster Ⅰ. Conclusion This was the first report describing that two main epidemic clusters were existed in CRF01_AE strains prevailing in the 4 provinces, Southern China. The vires in cluster Ⅰ was the dominant strain in this region, with shorter period of circulation and higher proportion seen in the HIV-infected population, which might belong to CRF01_AE strain with certain features facilitating the spread of the virus. The virus in cluster Ⅱ was highly homology with the CRF01_AE strains from Vietnam, and seemed to have had several events of epidemics in populations in border regions of China and Vietnam.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the incidence of lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) in men aged > or = 50 years and to achieve the correlation between LUTS (obstructive symptoms and stimulant symptoms) and ED.</p><p><b>METHODS</b>We investigated 245 men aged > or = 50 years and with regular sex mates using International Prostate Symptom Score (IPSS) and International Index of Erectile Function-5 (IIEF-5), designed diagnostic interrogation and medical examination, and statistically analyzed the results of IPSS, IIEF-5, LUTS and their correlation with erectile function.</p><p><b>RESULTS</b>The incidence of ED was 81.9% (140/171) among the men with LUTS, 73.1% (38/52), 82.1% (46/56) and 88.9% (56/63) respectively in the 50-59, 60-69 and > or = 70 age groups, with significant differences in IPSS, IIEF-5 (P < 0.01) and the severity of ED (P < 0.01) among different age groups. ED incidence was found significantly correlated with the severity of LUTS (r = 0.52, P < 0.01), 71.3% (57/80), 89.6% (60/67) and 95.8% (23/24) respectively in the groups of mild, moderate and severe LUTS. The mean scores on obstructive and stimulant symptoms were (3.1 +/- 3.6) and (6.8 +/- 4.9), and their correlation coefficients with IIEF-5 were r = -0.41 (P < 0.01) and r = -0.59 (P < 0.01), respectively.</p><p><b>CONCLUSION</b>The incidence of ED is high in men with LUTS and positively correlated with the severity of LUTS. Stimulant symptoms have greater influence than obstructive symptoms on the sexual life of old and middle-aged males.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the urodynamic diagnostic types of dysuria in female patients of different age groups.</p><p><b>METHODS</b>Six hundred and sixteen female patients with dysuria were evaluated from March 1997 to July 2008. No patients had history of nervous system disease and history of lower urinary tract operations. They had detrusor pressure-flow studies and uroflowmetry. The urodynamic diagnostic types were analyzed in 3 different age groups.</p><p><b>RESULTS</b>In 3 groups of 18 - 40 years, 40 - 60 years and > or = 60 years, the diagnosis of bladder outlet obstruction (BOO) had the highest proportion (54.8%, 59.1% and 45.0% respectively). The distribution of detrusor overactivity, detrusor under-activity and normal function had no significant difference between 3 groups. The distribution of BOO and acontractile detrusor had significantly difference between 3 groups. When groups of 18 - 40 years and 40 - 60 years were combined into 18 - 60 years group and compared with the older group, the proportion of BOO, acontractile detrusor and detrusor under-activity showed significantly difference. The proportions of BOO in the two groups were 57.3% and 45.0%, acontractile detrusor 15.6% and 23.9%, detrusor under-activity 17.4% and 25.0%, respectively. The proportion of reduced bladder sensation among detrusor under-activity patients in the older group was significantly higher.</p><p><b>CONCLUSIONS</b>In the urodynamic diagnoses of voiding difficulty in female patients, bladder outlet obstruction has the highest proportion. This proportion decreases in the older patients. The proportion of acontractile detrusor and detrusor under-activity increases in the older group.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the differences of the efficacy and different therapeutic drugs on the treatment of benign prostatic hyperplasia (BPH) in order to ensure the optimal indication for different BPH patients.</p><p><b>METHODS</b>A randomized, parallel-controlled, multicenter clinical trial was conducted. From September 2002 to December 2003 906 BPH patients were enrolled into 7 therapeutic groups, including selective-adrenoceptor antagonist (terazosin, doxazosin tamsulosin and naftopidil), 5 alpha-reductase inhibitor (finasteride and epristeride) and natural product (cernilton). International Prostate Symptom Score (IPSS) and Quality of Life (QOL), uroflowmetry, total prostatic volume (TPV) and transitional zone volume and residual urine were used as efficacy criteria.</p><p><b>RESULTS</b>According to the baseline, the IPSS and Qmax were significantly correlated to the prostatic volume and transitional zone volume (P < 0.01). At average follow-up of 6 months, significant improvements in IPSS, QOL, Qmax and residual urine volume were observed in each therapeutic group, and no difference in IPSS improvement was found among the groups. Prostatic volume and transitional zone volume were significant decreased in 5alpha-reductase inhibitor groups (P < 0.05). In patients with baseline TPV greater than 35.5 cm3, the improvement of Qmax was more significant than that in patients with TPV less than 35.5 cm3 in finasteride group (P < 0.01) (5.7 ml/s and 2.2 ml/s respectively), and more significant symptomatic improvements were also found in cernilton, doxazosin and naftopidil group. In each group, the improvement of symptom were more significant in patients with IPSS higher than 20 points (P < 0.01).</p><p><b>CONCLUSIONS</b>Each drug observed in this study can improve the subjective and objective symptoms significantly for BPH patients, especially for patients with higher IPSS baseline. When using 5alpha-reductase inhibitor, prostatic volume can be decreased significantly and more obviously subjective and objective improvement can be found in the patients with TPV greater than 35.5 cm3.</p>

ABSTRACT

<p><b>BACKGROUND</b>Benign prostate hyperplasia is one of the most common diseases affecting the health of the aging males. Watchful waiting is an acceptable management strategy for benign prostate hyperplasia in which the patient is monitored by the physician but receives no active intervention. The epidemiological data on this are lacking in China. Our study was designed to evaluate the changes of signs and symptoms of patients with benign prostate hyperplasia during management by watchful waiting in China.</p><p><b>METHODS</b>One hundred and forty-five patients with benign prostate hyperplasia aged > 50 years were enrolled in management by watchful waiting. All the patients were visited every 6 months and were given an International Prostate Symptom Score and Quality of Life questionnaire to complete. They also had uroflowmetry and were assessed using ultrasonography to get the volume of prostate, transition zone and amount of residual urine. The Student's t test, the Chi-square test, and variance analysis were used in the statistical analysis.</p><p><b>RESULTS</b>All patients were visited after 6 months, the mean volume of transitional zone was found to have increased by 1.6 ml (P < 0.01), International Prostate Symptom Score was increased by 0.8 (P < 0.01) and Quality of Life was increased by 0.2 (P < 0.01), and there was no statistical change in other data. Among these patients, 17.9% (26/145) visited again after 12 months when the data failed to show a statistically significant difference among the three groups (0, 6, and 12 months).</p><p><b>CONCLUSIONS</b>After one year's follow-up, the progression of benign prostate hyperplasia was slow and the clinical data did not undergo much change.</p>

ABSTRACT

Objective To evaluate the influence of duration of laser irradiation on histomorphometric meas- urements in experimentally tenotomized and repaired rabbit Achilles tendons and to explore the best irradiation time. Methods A total of 20 male New Zealand rabbits aged 10-12 weeks were used and randomly divided into 4 groups:a control group and three experimental groups.All the animals underwent surgical excised and then repair of their Achillis tendon.The animals in the control group were then treated with sham laser irradiation,while those in the three experimental groups were treated with 10,20 and 30 minutes of He-Ne laser irradiation(632.8 nm, 18.9 mW)daily,respectively,for 14 days.On the 28th day after surgical operation,the animals were sacrificed and their Achilles tendons were sampled.HE stain and Van Geison stain were used to observe morphometric changes of tendons.The SDS-PAGE electrophoresis method and CS-930 photodensity scan instrument were employed to measure the content of typesⅠandⅢcollagen.Results it was shown that laser irradiation enhanced cell proliferation,cel- lular content,granulation tissue formation and collagen deposition in laser-treated tendons,especially in those irradia- ted for 20 minute daily,as compared to the control group.TypeⅠand typeⅢcollagen levels were significantly in- creased at the 28th day in the healing tendons and the ratio of collagenⅢtoⅠincreased in all the 3 experimental groups,and the increase of both collagen content and ratio of collagen typeⅢtoⅠwas significantly greater in those ir- radiated 20 minutes daily(P

ABSTRACT

Objective To determine the prevalence of female urinary incontinence among Chinese people in different areas. Methods A sampling survey of urinary incontinence was conducted on 668 female adults in a Beijing community,the Uygur region and a residential district inside the First Hospital of Peking University with questionnaire. Results The prevalence of female urinary incontinence was 46.5%(94/202) in the Beijing community,43.8%(134/306) in the Uygur Region and 40.6%(58/143) in the residential district inside the First Hospital of Peking University.The ratios of those who consulted with doctors to the separate surveyed population were 24.5%(23/94),29.1%(39/134),13.8%(8/58),respectively. Conclusions The prevalence of female urinary incontinence is similar in different population.Only a few of these women went to doctors,especially among the hospital staff and workers.
