ABSTRACT

Benign prostatic hyperplasia (BPH) may lead to benign prostatic obstruction (BPO), which may result in bladder dysfunction. Based on the urodynamic analysis of bladder function of 793 BPO patients, bladder function could be classified into 3 stages and 6 types. Detrusor overactivity with impaired contractility (DHIC) is the transitional period of bladder function from compensation to decompensation. The indications of surgical therapy of bladder outlet obstruction (BOO) in different guidelines do not consider the bladder function. This paper emphasizes the importance of bladder function in the surgical choices for BOO, in order to select targeted and individualized surgical methods, and discusses the choice of surgical treatment for BPO from the perspective of bladder function.

ABSTRACT

【Objective】 To explore the clinical features and treatment outcomes of female urethral carcinoma so as to improve the awareness and prognosis of this rare malignant disease. 【Methods】 Clinical data of 8 cases of female urethral carcinoma treated during Jan. 2012 to Dec.2022 at the Department of Urology of Peking University People’s Hospital were retrospectively analyzed. The patients underwent urodynamic tests, cystourethroscopy and pathological biopsy to confirm the diagnosis. Traditional radical surgery was performed in 5 cases, and radical surgery for lower urethral cancer with bladder preservation was performed in 3 cases. 【Results】 The patients aged 36 to 68 years, with a mean of 53.75 years. Urinary obstruction, lower urinary tract symptoms and urethral masses were common manifestations. Urodynamic tests indicated bladder outlet obstruction. After surgical treatment, radical surgery for lower urethral cancer with bladder preservation showed advantages over traditional radical surgery in terms of intraoperative bleeding, operation time and postoperative hospital stay. 【Conclusion】 Female primary urethral carcinoma is rare but invasive. Early diagnosis and radical surgery are crucial for improving the prognosis. Radical surgery for lower urethral cancer with bladder preservation has better treatment outcomes and postoperative quality of life compared to traditional radical surgery. For such patients, symptoms should be closely monitored and timely diagnosis and treatment should be performed.

ABSTRACT

The outcomes of surgical treatment of benign prostatic hyperplasia (BPH) has been verified as it causes few complications. However, if complications develop, they will have significant impacts on patients’ quality of life. Therefore, in order to provide individualized treatments, patients’ general condition, expectations of treatment, clinical symptoms, prostate volume, advantages and disadvantages of different operative methods and operators’ mastery of operative methods should be considered to reduce the incidence of postoperative complications such as stress incontinence, urethral stricture and bladder neck contracture. This article discusses the choices of surgical interventions of BPH from the perspective of surgical safety and reduction of complications so as to improve the satisfaction of patients.

ABSTRACT

@#Joint hypermobility (JH) refers to the ability of joints to move beyond the 'normal' limits, which can be either physiologic or pathologic. Hypermobility spectrum disorders (HSDs) are a group of joint hypermobility-related clinical conditions. HSDs primarily affects the musculoskeletal system, predisposing the joints to subluxations or dislocations, and chronic pain. HSDs, however, may also manifest with symptoms such as fatigue, gastrointestinal disorders, and autonomic nervous system dysfunction, indicating multisystemic involvement that may impact psychological well-being. Although HSDs is usually not life-threatening, it is associated with poor quality of life. Currently, the molecular basis of HSDs remains unclear. The diagnosis of HSDs requires comprehensive medical evaluation and assessment. The main differential conditions/diagnoses include asymptomatic joint hypermobility, hypermobile Ehlers-Danlos syndrome (hEDS), and various musculoskeletal inflammatory or degenerative diseases. Asymptomatic joint hypermobility, HSDs, and hEDS are now viewed as a continuous spectrum. Due to limited awareness of the condition, individuals with asymptomatic joint hypermobility may experience overdiagnosis and overtreatment, while patients with HSDs may encounter prolonged misdiagnoses or underdiagnoses. Furthermore, individuals presenting with psychological symptoms may have all their somatic complaints erroneously attributed to psychological factors. These factors collectively impose unnecessary psychological and economic burdens on patients and their families. The multi-systemic and heterogeneous nature of HSDs necessitates a multi-disciplinary team (MDT) approach with a case manager in both the diagnosis and management processes. Additionally, patient education and self-management play pivotal roles in optimizing chronic disease management. This review aims to summarize the current state of diagnosis and management of HSDs and raise awareness of HSDs, providing a basis for the establishment and refinement of a multi-disciplinary diagnostic and management framework for HSDs in China.

ABSTRACT

Blau syndrome is a rare genetic disorder characterized by the a mix of granulomatous arthritis, uveitis, and dermatitis. Patients typically manifest multisystem involvement, including ocular, skin, and skeletal abnormalities. Blau syndrome is extremely rare, with a global incidence of less than one in a million among children. In this multidisciplinary consultation, we present a case of a 21-year-old young female patient having multisystemic involvement since early childhood. She was presented with multiple joint swelling, skin lesions, increased eye discharge, and accompanied by hypertension and arterial abnormalities, and received a diagnosis of uveitis. The patient had been receiving steroid treatment since the age of 6 and has tried various medications, with some improvement in joint swelling and ocular symptoms. Through this rare disease multidisciplinary consultation, we aim to provide guidance in the molecular diagnosis of the patient, multisystem assessment, and the selection and formulation of treatment plans. Additionally, we hope that by reporting this case, clinical physicians can gain a better understanding of the diagnosis and comprehensive treatment strategies for Blau syndrome, thereby improving the management and treatment of rare diseases.

ABSTRACT

Deep phenotyping is a precise and comprehensive approach used for the precise analysis and comprehensive assessment of multi-system phenotypes of the patients. The approach uses symptoms, signs, various medical examination and laboratory results, and other relevant medical information. In the clinical diagnosis and medical research of rare bone diseases, deep phenotyping plays a pivotal role. The realization of precision medicine primarily comprises three key dimensions: deep phenotyping, stratified medicine, and targeted therapy. The deep phenotyping is the basis for the latter two. Deep phenotyping not only facilitates fine subtyping of diseases, but also allows for the in-depth understanding of genetic data. The use of deep phenotyping requires stand- ardized terminology and specific procedures. Moreover, deep phenotyping shows substantial potential using the application of artificial intelligence technology particularly when combining with multi-omics techniques.

ABSTRACT

Objective:To evaluate the long-term efficacy of AdVance sling bulbar urethral suspension and artificial urethral sphincter (AUS) implantation in the treatment of moderate to severe male stress urinary incontinence.Methods:The clinical data of 12 male patients with urinary incontinence who underwent surgical treatment in Peking University People's Hospital from June 2011 to June 2017 were retrospectively analyzed. The median age was 75(64-80) years. There were 9 cases after radical prostatectomy and 3 cases after transurethral prostatectomy. Patients had a median history of urinary incontinence of 3(1-9) years, and needed an average of 8(5-10) pads per day. Among them, 5 patients had moderate urinary incontinence and 7 patients had severe urinary incontinence. All patients underwent urinary incontinence surgery for the first time. Among the 12 patients, 6 received AdVance sling ball urethral suspension (AdVance group), and 6 received AUS implantation (AUS group). The median age of the AdVance group was 72 (64-73) years. The median number of pads used daily was 6 (5-8) tablets. Urinary incontinence Quality of Life questionnaire (I-QOL) score was (15.0±5.4). Five patients had moderate urinary incontinence and one patient had severe urinary incontinence. In the AUS group, the median age was 78(76-80) years old, the median daily pad use was 8(6-10) tablets, and the I-QOL score was (16.7±5.1), all of which were severe urinary incontinence. The daily pad usage, I-QOL and postoperative complications were recorded at 1 and 5 years after operation.Results:All patients completed the operation successfully. The postoperative follow-up was 5-7 years (mean 5.5 years). In AdVance group, 1 patient with severe urinary incontinence had no significant improvement in postoperative symptoms at 1 year after operation. The other 5 patients showed significant improvement in urinary incontinence symptoms. In the AdVance group, the median number of pads used per day was 2.5 (1-10), and the I-QOL score was (75.0±28.1), which were all significantly improved compared with that before operation ( P<0.05). The median number of pads used per day in the AdVance group 5 years after operation was 2.5(1-10), and the I-QOL score was (78.3±29.3), which were significantly improved compared with those before operation (all P<0.01). In the AUS group, no pad was needed at 1 year after operation, which was significantly improved compared with that before operation ( P<0.01). Urethral erosion occurred in 2 cases 3 years after operation, and the AUS was removed. Urinary incontinence recurred and returned to the preoperative state without reoperation. The other 4 cases did not need to use the pad 5 years after operation. In AdVance group, 3 patients had perineal pain within 3 months after operation, which was related to activity and relieved spontaneously. No wound infection, urethral erosion and other complications occurred. Urethral erosion occurred in 3 cases in AUS group. Conclusions:AdVance sling ball urethral suspension is effective for patients with moderate stress urinary incontinence and has fewer complications. AUS implantation is effective for patients with severe male stress urinary incontinence. However, the long-term complications of this operation may affect the postoperative efficacy.

ABSTRACT

Objective:To establish the urodynamic classification of middle-aged and elderly men with benign prostatic obstruction(BPO), and to analyze the efficacy of transurethral resection of the prostate(TURP) on various types of patients.Methods:A retrospective analysis of middle-aged and elderly male patients with non-neurogenic lower urinary tract symptoms(LUTS) who underwent urodynamic tests from January 2010 to December 2018, including 793 patients with BPO. Urodynamics examination of detrusor without contraction needs to complete cystoscopy to diagnose BPO. During urodynamic examination, the detrusor uninhibited contraction induced by spontaneous or stimulation during the bladder filling period is diagnosed as overactivity of the bladder detrusor(DO), and the LinPURR chart indicates the detrusor underactivity(DU). Based on the persistence of BPO leading to DO, DU, and decreased bladder compliance, 793 male patients with BPO with LUTS were divided into four types, including type Ⅰ(BPO: n=164, 20.7%), type Ⅱ(BPO combined with DO: n=333, 42.00%), type Ⅲ(BPO combined with DU: n=267, 33.7%), type Ⅳ(BPO combined with decreased bladder compliance: n=29, 3.7%). The preoperative comparison between groups showed that the age of type Ⅰ-Ⅳ gradually increased, and the age of type Ⅰ was significantly smaller than other types [(67.3±8.2)years, (69.7±7.7)years, (71.5±7.9)years, (72.4±7.1)years, P<0.05]. Compared with other types, the type Ⅰ’s IPSS-S[(9.1±3.6)points vs.(10.4±3.1) points, (9.2±3.3) points, (10.4±3.1)points, P<0.05], IPSS-V[(13.5±3.4) points vs. (14.2±3.5)points, (14.0±3.5)points, (14.2±2.9)points, P<0.05], IPSS scores[(22.6±5.4)points, (24.7±4.9)points, (23.1±5.3)points, (24.6±4.7)points, P<0.05] were significantly lower than other groups, the maximum bladder capacity [(332.6±83.2)ml vs.(221.4±80.8)ml, (286.7±108.2)ml, (242.3±103.4)ml, P<0.05], the functional bladder capacity was significantly higher than other types[(215.2±90.0)ml, (148.5±76.0)ml, (154.9±87.2)ml, (121.2±72.9)ml, P<0.05]. Type Ⅱ’s IPSS-S[(10.4±3.1)points vs.(9.1±3.6)points, (9.2±3.3)points, P<0.05], nocturia frequency[(3.7±1.8)times vs.(3.2±1.8)times, (3.2±1.6)times, P<0.05], IPSS score[(24.7±4.9)points vs.(22.6±5.4)points, (23.1±5.3)points, P<0.05], quality of life scores [(4.9±0.9) points, (4.6±0.9)points, (4.6±0.9)points, P<0.05] was significantly higher than type Ⅰ and type Ⅲ ( P<0.05). Type Ⅲ and Ⅳ had higher residual urine than type Ⅱ[(121.3±96.4)ml, (121.3±96.4)ml vs.(71.2±73.5)ml, P<0.05]. Type Ⅳ’s IPSS-S[(10.4±3.1)points vs. (9.1±3.6)points, (9.2±3.3)points, P<0.05], IPSS-V[(14.2±2.9) points vs.(13.5±3.4)points, (14.0±3.5)points, P<0.05], the frequency of nocturia[(3.8±1.9)times vs.(3.2±1.8)times, (3.2±1.6)times, P<0.05] was significantly higher than that of type Ⅰ and type Ⅲ, and the quality of life score was higher than type Ⅰ and type Ⅲ[(4.3±0.8)points vs.(4.7±0.9)points, (4.6±0.9)points, P<0.05]. type Ⅱ and type Ⅳ’s bladder compliance[(21.4±24.2)ml/cmH 2O, (11.0±11.4)ml/cmH 2O vs.(33.9±23.7)ml/cmH 2O, (33.1±32.7)ml/cmH 2O, P<0.05], maximum bladder capacity[(221.4±80.8)ml, (242.3±103.4)ml vs.(332.6±83.2)ml, (286.7±108.2)ml, P<0.05], functional bladder capacity[(148.5±76.0)ml, (121.2±72.9)ml vs.(215.2±90.0)ml, (154.9±87.2)ml, P<0.05] were significantly less than type Ⅰ and type Ⅲ( P<0.05). From November 2016 to November 2018, 60 middle-aged and elderly male patients with confirmed BPO and TURP were selected, including type Ⅰ( n=17, 28.3%), type Ⅱ ( n=23, 38.3%), and Ⅲ type ( n=11, 18.3%), Ⅳ type( n=9, 15.1%). Type IV patients are significantly older than other types ( P<0.05), bladder compliance is significantly worse than other types( P<0.05), the maximum bladder capacity is smaller than other types( P<0.05). The follow-up started 3 months after the operation. The content of the follow-up included IPSS, IPSS-S, IPSS-V, nocturia frequency, undisturbed sleep time, nocturia quality of life score, and life quality score. Results:The IPSS scores of type Ⅰ, type Ⅱ, and type Ⅲ after TURP were significantly improved compared with preoperative(19.8±6.2 vs.3.4±1.8; 21.9±5.2 vs.4.6±2.6; 21.5±6.2 vs.5.7±4.6, P<0.05), type Ⅳ urine storage symptom score (9.1±4.1 vs.4.3±3.7), nocturia frequency(3.6±1.5vs.2.3±1.6), nocturia quality of life score (25.3±6.9 vs.31.4±13.7) Compared with preoperatively, there was no significant improvement( P>0.05). The quality of life score improvement of type Ⅳ patients was significantly lower than that of type Ⅰ, type Ⅱ, and type Ⅲ (10.9±9.1 vs.12.2±9.0, 14.4±5.7, 12.7±5.8, P<0.05). The IPSS score of type Ⅳ patients was significantly higher than that of type Ⅰ(7.0±5.8 vs.3.4±1.8), and the nocturia quality of life score was significantly lower than that of each group (31.4±13.7 vs.37.5±4.2, 38.7±3.5, 37.8±3.8, P<0.05). Conclusions:For middle-aged and elderly men with BPO, we divide them into four types based on the results of urodynamic examinations, type Ⅰ(simple BPO), type Ⅱ(BPO combined with DO), type Ⅲ(BPO combined with DU), type Ⅳ(BPO combined with bladder compliance decline). Type Ⅰ patients have the best bladder function, and TURP has the best effect; type Ⅱ has a high symptom score and poor quality of life, and can benefit after TURP; type Ⅲ bladder function is poor, and surgery should be performed as soon as possible to prevent further deterioration of bladder function; type Ⅳ bladder function is the best poor, IPSS score and quality of life score are high, TURP surgery is not effective.

ABSTRACT

Objective:To investigate the clinical effect of Jiedu Limai decoction in septic patients with syndrome of heat-toxin exuberance.Methods:A prospective randomized controlled trial was conducted. From March 2019 to April 2020, septic patients with syndrome of heat-toxin exuberance admitted to intensive care unit (ICU) of Shanghai General Hospital and Songjiang Branch of Shanghai General Hospital were enrolled as the research objects, and they were divided into routine treatment group and Jiedu Limai decoction group by the random number table method. Patients in both groups were given standard treatment in accordance with the guidelines, and patients in the Jiedu Limai decoction group were given Jiedu Limai decoction in addition to the standard treatment, once a day for 14 days. The 28-day survival of patients of the two groups were recorded, the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, coagulation indexes, infection indexes, inflammatory cytokines and organ function indicators before treatment and 7 days after treatment in both groups were recorded, and the prognosis of the two groups were recorded.Results:A total of 259 patients with infection or clinical diagnosis of infection admitted during the experimental observation period were included, and those who did not meet the Sepsis-3 diagnostic criteria, more than 80 years old or less than 18 years old, with multiple tumor metastases, autoimmune system diseases, with length of ICU stay less than 24 hours, with acute active gastrointestinal bleeding and with incomplete data were excluded. One hundred patients were finally enrolled, with 50 patients in the routine treatment group and 50 patients in the Jiedu Limai decoction group. There were no statistically significant differences in coagulation indexes, infection indicators, inflammatory cytokines and organ function indicators before treatment between the two groups. After 7 days of treatment, the coagulation indexes, infection biomarkers and inflammatory cytokines in the Jiedu Limai decoction group were significantly lower than those in the routine treatment group [D-dimer (mg/L): 2.2 (1.8, 8.5) vs. 4.0 (1.5, 8.7), fibrinogen (Fib, g/L): 3.7 (3.4, 4.3) vs. 4.2 (3.7, 4.3), fibrinogen degradation product (FDP, mg/L): 7.2 (5.4, 10.2) vs. 13.2 (9.2, 15.2), procalcitonin (PCT, μg/L): 0.4 (0.2, 2.9) vs. 0.5 (0.2, 0.9), C-reactive protein (CRP, mg/L): 50.1 (9.5, 116.0) vs. 75.1 (23.5, 115.2), interleukin-6 (IL-6, ng/L): 31.6 (21.6, 81.0) vs. 44.1 (14.0, 71.3), all P < 0.05], and the levels of B-type brain natriuretic peptide (BNP) and kidney injury molecule-1 (KIM-1) were significantly lowered [BNP (ng/L): 261.1 (87.5, 360.3) vs. 347.3 (128.8, 439.4), KIM-1 (μg/L): 0.86 (0.01, 1.40) vs. 1.24 (1.05, 1.57), both P < 0.05]. Compared with the routine treatment group, the number of new organ failure in the Jiedu Limai decoction group was decreased (30.0% vs. 50.0%, P < 0.05). Although there was no significant difference in 28-day mortality between the two groups ( P > 0.05), the 28-day mortality in the Jiedu Limai decoction group was lower than that in the routine treatment group (18.0% vs. 24.0%). Conclusion:Combining Jiedu Limai decoction to the sepsis guideline in treating syndrome of heat-toxin exuberance can effectively improve patients' coagulation function, the situation of heart and renal injury, reduce the level of inflammatory cytokines, and fewer people develop new organ failure after treatment.

ABSTRACT

Objective:To investigate the effect of transurethral prostatectomy (TURP) on patients with detrusor underactivity (DU).Methods:From January 2015 to January 2019, 72 male patients from Peking University People’s hospital who underwent TURP treatment were retrospectively analyzed. The age of all patients range from 51 to 89, with an average age of 72 years old. All patients underwent urodynamic examination before surgery. The patients were divided into three groups according to BCI and P detQmax. DU group(BCI<100 and P detQmax≤40 cmH 2O) consisted of 31 patients. Then DU patients were divided into two groups according to the P detQmax: Group A, P detQmax≤20 cmH 2O, involving 9 patients; Group B, 20 cmH 2O<P detQmax≤40 cmH 2O, involving 22 patients. Non-DU group(BCI≥100 and 40 cmH 2O<P detQmax≤60 cmH 2O), also named the control GroupC, included 41 patients. There was no statistically significant difference in term of age and duration of disease among the three groups ( P<0.05). Preoperative international prostate symptom scores(IPSS)of the three groups were(26.40±5.54), (21.04±4.61)and(18.53±4.41), respectively. The quality of life score (QOL) were(4.70±1.34), (3.37±1.11)and(3.49±1.34), respectively. The Q max were(4.60±2.63), (8.48±2.47)and(11.38±4.00)ml/s, respectively. The residual urine volume (PVR) were(152.90±75.26), (90.78±51.97)and(53.23±38.98)ml, respectively. The preoperative IPSS and QOL of patients in group A were significantly higher than those in group B and group C, and the difference was statistically significant ( P<0.05), whereas the difference between group B and group C was not statistically significant ( P>0.05). The preoperative Q max of group A was significantly inferior than that of group B and C, with statistically significant difference ( P<0.05) and group B was significantly inferior than group C, with statistically significant difference ( P<0.05). The preoperative PVR of group A was significantly higher than that of group B and group C, with statistically significant difference ( P<0.05)and group B was significantly higher than group C, with statistically significant difference ( P<0.05). The above indicators were followed up to compare the improvement for the three groups of patients. Seventy-two patients were followed up for free Q max(fQ max) PVR, IPSS and QOL score from March 2019 to June 2019. Results:The 72 patients were followed up for 3 to 52 months, with an average of 31.1 months. Postoperative IPSS of the three groups were(25.50±2.84), (16.78±4.04)and(14.98±3.41), respectively. The QOL were (2.90±1.29), (2.67±0.88)and(2.53±0.92), respectively. The fQ max was (5.44±2.60), (10.30±3.68)and(13.07±3.51) ml/s, respectively, and PVR was(104.00±46.00), (76.81±46.74)and(35.64±26.17)ml, respectively. Compared with the preoperative parameters, QOL in group A was significantly improved, with statistically significant difference ( P<0.05) and the IPSS, fQ max and PVR in group A were improved, but the difference was not statistically significant ( P>0.05). The IPSS, QOL, fQ max and PVR in group B and C were significantly improved compared with the preoperative parameters, and the difference was statistically significant ( P<0.05). Conclusions:The subjective and objective indicators of DU patients can be improved after TURP, while for those patients whose P detQmax≤20 cmH 2O, only QOL can be improved significantly, and the other indicators can not be improved. Therefore, adequate communication should be made before surgery to inform reasonable expectations for the DU patients.

ABSTRACT

Objective:To evaluate the effect of transurethral resection of the prostate on nocturia and sleep quality in men with benign prostatic hyperplasia.Methods:This retrospective study included 122 patients who underwent TURP(transurethral resection of the prostate) for BPH(benign prostatic hyperplasia)from December 2016 to December 2018.The age was(69.7±7.9)years old. There was 20 cases with diabetes and 40 cases with hypertension. The preoperative mean prostate volume was (64.4±41.2)ml and mean BMI was (24.3±2.7)kg/m 2. The preoperative IPSS score was (20.5±5.5) points, the number of nocturia events(assessed by the seventh question of IPSS) was (4.4±1.9) times, hours of undisturbed sleep (HUS) was (1.7±1.0) h, 110 cases with HUS <3 h; nocturia quality-of-life questionnaire (N-QOL) was (24.9±6.3) points, quality of life (QOL) was (4.4±0.9) points. 111 patients had the urodynamic examination done. The maximum urine flow rate was (6.4±3.1) ml/s, the maximum bladder volume was (318.5±83.6) ml, the residual urine volume was (153.9±158.9) ml, and the maximum detrusor pressure was (78.4±35.5)cmH 2O.Detrusor muscle strength decreased in 27 cases, 18 cases had OAB, 9 cases of effective bladder capacity declined and 60 cases had bladder outlet obstruction. 42 cases had an effective bladder volume <200 ml, of which 33 had a maximum bladder capacity >200 ml with nocturia (4.5±1.9) times, 9 cases had a maximum bladder capacity ≤200 ml with nocturia (4.7±1.7) times. All 122 patients were treated with TURP. Result:122 patients were followed up for 3-20 months. After operation the number of nocturia significantly decreased to (1.9±1.23) times ( P<0.05), HUS significantly improved to(3.4±1.3) h ( P<0.05), and 91 cases had HUS ≥3 with 82.7% remission rate; N-QOL significantly improved to (37.3±6.7) points ( P<0.05), IPSS significantly decreased to (4.9±4.2) points ( P<0.05), and QOL significantly decreased (0.8±0.9) points ( P<0.05). 121 patients had nocturia ≥2 voids before surgery, and 96 patients had improved (≥50% reduction of nocturnal frequency). There were 68 patients with nocturia ≥2 voids after operation with total score of preoperative IPSS (21.8±5.3), and 54 patients with nocturia <2 voids with total score of preoperative IPSS (19.2±5.5)( P<0.05). Patients with a effective bladder capacity less than 200 ml were divided into a group with a maximum bladder volume ≤200 ml and a group with a maximum bladder capacity>200 ml. The nocturia did not improve significantly after surgery ( P>0.05) in the group with a maximum bladder volume ≤200 ml, and the nocturia in the group with a maximum bladder capacity >200 ml had significantly improvement ( P<0.05). The group with a maximum bladder capacity ≤200 ml had nocturia (3.4±1.5) times after surgery, which was no significant different from that before surgery ( P=0.12); nocturia (1.9±1.1) times after operation in the group with maximum bladder volume>200 ml, and there was significant difference compared with before surgery ( P<0.05). Conclusion:TURP can significantly prolong the HUS of BPH patients with nocturia, and improve the life and sleep quality of patients. TURP partly reduces the number of nocturia, but some patients still suffer from nocturia after operation. The high total score of IPSS before operation and the maximum bladder volume ≤200 ml are the risk factors for nocturia after operation.

ABSTRACT

Epigenetics is the main mechanism that controls transcription of specific genes with no changes in the underlying DNA sequences. Epigenetic alterations lead to abnormal gene expression patterns that contribute to carcinogenesis and persist throughout disease progression. Because of the reversible nature, epigenetic modifications emerge as promising anticancer drug targets. Several compounds have been developed to reverse the aberrant activities of enzymes involved in epigenetic regulation, and some of them show encouraging results in both preclinical and clinical studies. In this article, we comprehensively review the up-to-date roles of epigenetics in the development and progression of prostate cancer. We especially focus on three epigenetic mechanisms: DNA methylation, histone modifications, and noncoding RNAs. We elaborate on current models/theories that explain the necessity of these epigenetic programs in driving the malignant phenotypes of prostate cancer cells. In particular, we elucidate how certain epigenetic regulators crosstalk with critical biological pathways, such as androgen receptor (AR) signaling, and how the cooperation dynamically controls cancer-oriented transcriptional profiles. Restoration of a "normal" epigenetic landscape holds promise as a cure for prostate cancer, so we concluded by highlighting particular epigenetic modifications as diagnostic and prognostic biomarkers or new therapeutic targets for treatment of the disease.

ABSTRACT

Objective To introduce a urodynamic classification of female patients with symptoms of overactive bladder(OAB) and discuss its clinical significance.Methods From January 2015 to January 2017,62 female patients from Peking University People's Hospital who diagnosed clinically with OAB and underwent preoperative urodynamic test were involved in this study.Female OAB patients can be stratified into four groups based on the chief complaints and the urodynamic test,including type Ⅰ-no evidence of detrusor overactivity(DO) on urodynamic test,patients can feel urgency and have no urinary incontinence,type Ⅱ-involuntary detrusor contraction present,patients aware and able to abort them and have no urinary incontinence,type Ⅲ-involuntary detrusor contraction present,patients aware and able to contract the sphincter but can not abort contractions and have urinary incontinence and type Ⅳ-contractions present,and patients unaware and unable to contract the sphincter or abort contractions and have urinary incontinence.According to the classification,the amount of the four types of OAB patients were 8,22,25 and 7,respectively.The data of height,age,weight showed no statistical significance (P > 0.05).The amount of the concomitant diseases of the type Ⅰ,Ⅱ and Ⅲ showed no obviously difference (P > 0.05),but the type Ⅳ was higher than the other three types(P < 0.05).The preoperative OABSS(6.38 ± 1.51 vs.6.41 ± 1.76,P > 0.05) and AUASS scores (16.38 ± 5.26 vs.16.59 ± 5.11,P > 0.05) of the type Ⅰ and Ⅱ have shown no obviously difference.The preoperative OABSS(9.00 ± 2.35 vs.9.71 ± 3.04,P > 0.05) and AUASS(20.59 ± 3.95 vs.22.00 ± 4.97,P > 0.05) scores of the type Ⅲ and Ⅳ have shown no obviously difference.The preoperative scores of the OABSS scores and AUASS scores of the type Ⅲ and the type ⅣV were obviously higher than that of the type Ⅰ and the type Ⅱ (P < 0.05).In this study,16 of the 62 patients were treated with tolterodine,46 patients were treated with solifenacin,with the average duration of drug therapy of 3.4 months (0.5-20.0 months).The postoperative scores of the OABSS and AUASS were followed up.The treatment outcomes among different OAB types were compared.Results The 62 patients were followed up from 6 to 20 months,with an average of 11.2 months.The improvement of the OABSS scores of the type Ⅰ and Ⅱ(3.63 ± 0.74 vs.3.86 ± 0.89,P > 0.05) have shown no obviously difference.The improvement of the OABSS scores of the type Ⅲ (6.40 ± 1.17) were obviously higher than the type Ⅰ,Ⅱ and Ⅳ (1.71 ± 1.38) (P < 0.05).The improvement of the OABSS scores of the type Ⅳ were obviously inferior to the type Ⅰ,Ⅱ and Ⅲ (P < 0.05).The improvement of the AUASS scores of the type Ⅰ and Ⅱ (11.75 ± 4.33 vs.12.30 ±5.34,P >0.05)have shown no obviously difference.The improvement of the AUASS scores of the type Ⅲ (15.28 ± 4.32)were obviously higher than the type Ⅰ,Ⅱ and ⅣV (8.14 ± 4.34) (P < 0.05).The improvement of the AUASS scores of the type ⅣV were obviously inferior to the type Ⅰ,Ⅱ and Ⅲ (P < 0.05).Conclusions The type Ⅳ OAB presented with the worst outcome and the type Ⅲ OAB presented with the best among the four types of OAB.The classification system will have a suggestive significance to predict the prognosis and the therapeutic effect of the patients with OAB.

ABSTRACT

Objective To evaluate the clinical outcome and the problems of patients who have performed the clean intermittent self-catheterization(CISC)through detailed telephone interviews and then develop corresponding measures to solve.Methods In this study,telephone interviews were carried out in 27 patients who were diagnosed as detrusor underactivity from January 2011 to September 2015,and received CISC as treatment.They were asked to finish the micturition diary and answer questions from 4 questionnaires of which the first one was IPSS and the other 3 parts were ICDQ,InCaSaQ,and SF-36. Results 27 patients completed the follow-up interview,and the median time of CISC is 1 8 months.The average frequency of voiding by catheterization was 3.7 times a day.After the intervention of CISC,the symptoms of voiding difficulty and chronic urinary retention in all the 27 patients were relieved.11.1% of the 27 patients experienced urinary tract infection.The average ICDQ score was 0.4 and 88.9% of them were satisfied with the current states and what they experienced after performing CISC.The average InCaSaQ score was 2.15.The average physical and mental score from SF-36 questionnaire was 76.9 and 79.2 respectively.Conclusions CISC is an easy-to-do operation that relieves retention effectively and protects upper urinary tract function.The incidence of complications is quite low and the influence on quality of life is moderate,making it easy to persist in the long term of bladder management.

ABSTRACT

Objective To evaluate the value of the prostate imaging reporting and data system version 2 (PI-RADS version 2) for the diagnosis of prostate cancer.Methods A total of 243 patients who underwent multiparametric 3T prostate MRI followed by prostate biopsy or radical prostatectomy were included.111 patients were in PSA gray zone(4.0-10.0 ng/ml).PI-RADS version 2 scores for each patient was assigned by two readers independently.Reference standard was obtained by histopathology.Positive predictive value (PPV) for prostate cancer and clinically significant cancer were compared among patients with different PI-RADS Version 2 scores using chi-square trend test.Receiver operating characteristic (ROC) curve was performed to assess diagnostic accuracy of the PI-RADS version 2 scores for prostate cancer detection,and evaluate the difference in diagnostic efficiency between transition zone and peripheral zone.Results Two hundred and eighty five suspicious foci from the 243 patients were finally recruited to this study,131 of which were diagnosed as prostate cancer according to pathology.There was significant difference in PPV for prostate cancer and clinically significant cancer among patients with different PI-RADS version 2 scores (score 1:8.0%;score 2:10.1%;score 3:49.2%;score 4:61.1% score 5:87.9%,P<0.01),(score 1:0;score 2:5.1%;score 3:31.1%;score 4:59.3% score 5:88.9%,P < 0.01).When PI-RADS version 2 score was 3,Youden index was maximum (0.53),the sensitivity was 92.4% and the specificity was 61.0%.The ROC analysis revealed that the area under the curve (AUC) of prostate cancer incidence in transition zone was similar to that in peripheral zone with 0.86(95% CI 0.78-0.95) vs.0.83(95% CI 0.77-0.89).There were 111 patients in PSA gray zone,33 of whom were diagnosed as prostate cancer.If we used PI-RADS version 2 score 3 as the cut-off point,47 out of 111 patients would avoid unnecessary prostate biopsies with 4 misdiagnosed nonsignificant prostate cancer.Conclusions The value of PI-RADS version 2 score is positively associated with PPV for prostate cancer.PI-RADS version 2 seems to have good diagnostic accuracy in prostate cancer detection.Clinical application of PI-RADS version 2 may help to reduce the number of unnecessary biopsy.

ABSTRACT

Objective: To evaluate the medium and long term outcomes of tension-free mid-urethral sling in the treatment of female patients with mixed urinary incontinence (MUI).Methods: Twenty-six patients who underwent the tension-free mid-urethral sling procedure for MUI from April, 2010 to September, 2016, were followed up.Four of the 26 patients underwent retropubic tension free mid-urethral sling (TVT), and 22 of them underwent transurethral middle obturator sling (TOT).Scales were used in the follow-up, such as urinary incontinence severity score (UISS), detrusor instability score (DIS), incontinence quality of life scale evaluation (I-QOL), Urogenital Distress Inventory short form (UDI-6), and the outcomes before and after the procedure were compared.Results: The mean age was 62 years, with a range of 42-80 years.The mean body mass index (BMI) was 26.82 kg/m2, with a range of 21.48-31.14 kg/m2.The mean follow-up time was 26 months, with a range of 8-69 months.Twelve patients never took M-blockers and the rest 14 patients took M-blockers within two weeks.None of the pa-tients had complications, including dysuria, injury of bladder, urethra, obturator vessel or nerve during the surgery.After pulling out the catheter, no one suffered moderate or severe pain or difficulty of urination.The overall cure rate for stress urinary incontinence (SUI) was 96.15% with 25 patients cured, and for urge urinary incontinence (UUI) was 76.92% with 20 patients cured.The patients'' life quality also improved significantly (P<0.05).Conclusion: Ten of the 26 patients showed an overactive bladder according to urodynamic study, from whom all of the six failed patient were.And 16 patients didn''t show an overactive bladder, which may due to two reasons.One is that their sense of urge is not so serious, the other one is that their sense of urge is from urethra.Proximal urethra is full of nerve, which plays a role in sense and urine control.The sense of urge may come from urethra instead of bladder.Tension-free mid-urethral sling procedure is an effective treatment for women with mixed urinary incontinence.Even without taking the M-blockers, the cure rate for urge incontinence reached 76.92%.The efficacy of surgery remained stable in medium and long term, and the patients'' quality of life improved significantly.

ABSTRACT

Objective:To assess the changing trends in Gleason score (GS)of Chinese prostate carci-noma (PCa)from January 1995 to December 2014.Methods:In the study,875 patients admitted to hospital from January 1995 to December 2004 (1995 -2004)and from January 2005 to December 2014 (2005 -2014)were divided into two groups.The mean levels and proportions of GS,primary and se-condary grades were studied.The patients were divided into four groups according to age: <60,60 -69,70 -79 and ≥80 years.Types of specimen included needle biopsy (NB),transurethral resection of the prostate (TURP)and radical prostatectomy (RP).Histological types were made up by acinar carci-noma and other types (including atrophic,pseudohyperplastic,foam,signet ring cell and ductal carcino-ma,and so on).The total prostate-specific antigen (tPSA)involved groups of <20.0 μg/L and ≥20.0 μg/L.We observed the mean levels and proportions of GS in age,types of specimen,histological types and total prostate-specific antigen in different periods,and used SPSS 17.0 software for statistical analysis.Results:Compared with 1995 -2004,the mean levels of GS,primary and secondary grades decreased 0.32 (P =0.003),0.19 (P =0.001)and 0.12 (P =0.016)in 2005 -2014,respectively. The proportions of ≤6 in GS increased 10.9% (P =0.003),and ≥8 decreased 14.0% (P <0.001). The difference of GS 7 was not statistically significant.In the primary grade,the ratio of grades≤3 in-creased 12.8% (P =0.001 ),and grade 4 decreased 7.4% (P =0.037),grade 5 decreased 5.5%(P =0.007).The ratio of secondary grades≤3 increased 7.6% (P =0.037).The difference of grades 4 and 5 was not statistically significant.Conclusion:GS in Chinese patients with PCa showed a down-ward trend,which is one of the notable features in the past 20 years in China.The types of specimen and age are important factors in GS,while the histological types and tPSA have less impact on the GS.
