OBJECTIVETo evaluate the urodynamic risk factors of upper urinary tract dilatation (UUTD) secondary to spinal cord injury (SCI).
METHODSNinety-six SCI patients of Tangshan earthquake were divided into 2 groups by ultrasonography: 16 SCI patients (group A) with UUTD and 80 SCI patients (group B) without UUTD received urodynamic test. Responses were evaluated using single and multiple analysis after examination.
RESULTSThe incidence of male was significantly higher than that of female. Residual urine volume, maximum cystometric capacity, detrusor leak point pressure and the incidence of bladder low compliance in group A were significantly higher than those in group B. There were no significant differences in age, the incidence of detrusor hyperreflexia, relative safe bladder capacity, the incidence of detrusor-sphincter dyssynergia, maximum flow rate and maximum urethral closure pressure between 2 groups. Bladder low compliance was cardinal risk factors according to Logistic regression analysis.
CONCLUSIONAn early urodynamic examination and treatment for SCI patients are important to prevent from bladder low compliance and upper urinary tract damage.

Lower urinary tract dysfunction-such as urinary incontinence (UI), detrusor overactivity, and benign prostatic hyperplasia-is prevalent in elderly persons. These conditions can interfere with daily life and normal functioning and lead to negative effects on health-related quality of life. UI is one of the most common urologic conditions but is poorly understood elderly persons. The overall prevalence of UI increases with age in both men and women. Elderly persons often neglect UI or dismiss it as part of the normal aging process. However, UI can have significant negative effects on self-esteem and has been associated with increased rates of depression. UI also affects quality of life and activities of daily living. Although UI is more common in elderly than in younger persons, it should not be considered a normal part of aging. UI is abnormal at any age. The goal of this review is to provide an overview of the cause, classification, evaluation, and management of geriatric lower urinary tract dysfunction.

Nephrogenic diabetes insipidus (DI) secondary to chronic urinary tract obstruction is a rare disease. The exact cause is unknown but it is likely that increased collecting duct pressures cause damage to the tubular epithelium, resulting in insensitivity to the action of arginine-vasopressin (AVP). A 77-year-old man complaining of polyuria and polydipsia was treated with alpha glucosidase inhibitor under the impression of polyuria due to diabetes mellitus. But his symptoms did not improve. Water deprivation and AVP administration study revealed that the patient had nephrogenic DI. Urinary tract obstruction due to an enlarged prostate was suggested as a principal cause of nephrogenic DI. The patient underwent transurethral resection of the prostate and bilateral subcapsular orchiectomy. After surgery, the urine osmolarity was normalized and the patient became symptom-free. We report a case of nephrogenic DI due to obstructive uropathy which was cured by surgery eliminating obstruction.

AIMTo evaluate the effects of metabolic profiles on lower urinary tract symptoms (LUTS) in men with erectile dysfunction (ED).
METHODSA total of 75 impotent men aged 25-75 years old (mean 58.1 years) were included in the study on a prospective basis. Patients were evaluated with a complete history, physical examination, anthropometry and metabolic profiles. LUTS were assessed using the International Prostate Symptom Score (IPSS).
RESULTSOverall, there was no correlation between the IPSS and continuous parameters. However, when continuous variables were categorized, some parameters were significantly associated with LUTS. Patients with triglyceride level of 150 mg/dL or higher had more severe symptoms than those with triglyceride levels less than 150 mg/dL (19.4 +/- 2.4 vs. 14.3 +/- 1.1, P = 0.033). When 40 mg/dL was chosen as the high-density lipoprotein (HDL)-cholesterol cut-off level, the IPSS was significantly different between the two groups divided by 40 mg/dL (19.4 +/- 2.6 for HDL-cholesterol < 40 mg/dL vs. 14.4 +/- 1.0 for HDL-cholesterol = or > 40 mg/dL, P = 0.042). The area under the receiver operating characteristic curve (AUROCC) of triglyceride was 65.7% (95% confidence interval [CI], 52.6%-82.3%; P = 0.034) for severe LUTS. However, the AUROCC for 'HDL-cholesterol' was not significant (area, 65.4%; 95% CI, 48.2%-82.7%; P = 0.062). No other factors were determined to be significant in this regard.
CONCLUSIONThe results of the present study indicate that some metabolic profiles might influence LUTS in men with ED.

OBJECTIVETo review and summarize the experience of urethral reconstruction using lingual mucosal graft for the treatment of complex hypospadias.
METHODSWe evaluated the methods using lingual mucosal graft for the treatment of complex hypospadias. The dorsal inlay graft method and the tube graft method were used in our study.
RESULTSFrom Nov. 2010 to Oct. 2011,21 cases were treated. All the cases had at least one failed hypospadisa surgery before. The dorasl inlay grafting technique was used for 16 patients, the tube grafting technique was carried out in 5 patients(2 cases received Tube + Duply method). The follow-up period ranged from 3 months to 12 months (by average 6 months). The success rate of the methods was 61.9% with complications in 8 cases. Urethral fistula developed in 3 patients and urethral stricture developed in 5 patients. All cases who suffered stricture received the tube grafting technique. The fistula and urethral stricture were occurred at the site of the urethral termonoterminal anostomosis. Urethral stricture is the most common complication after the tube graft method for the treatment of the complex hypospadias.
CONCLUSIONSHarvesting the lingual mucosal graft is feasible and easy to perform. The complex hypospadias repair technique using lingual mucosal graft method provides good results. There fore it should be one of the preferred techniques for complex hypospadias repair. The dorsal inlay grafting technique has lower complication rate than the tube grafting technique. Early and regular urethral sounding should be carried out when patients received the tube graft method.

The clinical effect of laparoscopic rectal cancer curative excision with pelvic autonomic nerve preservation (PANP) was investigated. This study evaluated the frequency of urinary and sexual dysfunction of 149 male patients with middle and low rectal cancer who underwent laparoscopic or open total mesorectal excision with pelvic autonomic nerve preservation (PANP) from March 2011 to March 2013. Eighty-four patients were subjected to laparoscopic surgery, and 65 to open surgery respectively. The patients were followed up for 12 months, interviewed, and administered a standardized questionnaire about postoperative functional outcomes and quality of life. In the laparoscopic group, 13 patients (18.37%) presented transitory postoperative urinary dysfunction, and were medically treated. So did 12 patients (21.82%) in open group. Sexual desire was maintained by 52.86%, un-ability to engage in intercourse by 47.15%, and un-ability to achieve orgasm and ejaculation by 34.29% of the patients in the laparoscopic group. Sexual desire was maintained by 56.36%, un-ability to engage in intercourse by 43.63%, and un-ability to achieve orgasm and ejaculation by 33.73% of the patients in the open group. No significant differences in urinary and sexual dysfunction between the laparoscopic and open rectal resection groups were observed (P>0.05). It was concluded that laparoscopic rectal cancer radical excision with PANP did not aggravate or improve sexual and urinary dysfunction.

9.Common approach to managing lower urinary tract symptoms and erectile dysfunction.

Asian Journal of Andrology 2008;10(1):45-53
The present paper serves as a review of the associations between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED), with a focus on common and combined pathways for treatment. LUTS and ED are common conditions seen in general urologic practice. Research has started to establish epidemiologic and pathophysiologic links between the two conditions and a strong association confirmed across multiple studies. Men seeking care for one condition should always be interviewed for complaints of the other condition. Proposed common pathways include alpha-1 adrenergic receptor imbalance, Rho-kinase overactivity, endothelial cell dysfunction and atherosclerosis-induced ischemia. Medical therapy has replaced surgery as the first-line treatment for LUTS in most patients, with the incorporation of alpha-adrenergic receptor antagonists (alpha-ARAs) and 5-alpha-reductase inhibitors (5-ARIs) into everyday practice. Treatment with alpha-ARAs contributes to some improvement in ED, whereas use of 5-ARIs results in worsened sexual function in some patients. Phosphodiesterase-5 (PDE-5) inhibitors have revolutionized the treatment of ED with a simple oral regimen, and new insights demonstrate a benefit of combined use of PDE-5 inhibitors and alpha-ARAs. The mechanisms of action of these medications support these observed benefits, and they are being studied in the basic science and clinical settings. In addition, novel mechanisms for therapy have been proposed based on clinical and research observations. The minimally invasive and surgical treatments for LUTS are known to have adverse effects on ejaculatory function, while their effects on erectile function are still debated. Much remains to be investigated, but it is clear that the associations between LUTS and ED lay the foundation for future therapies and possible preventative strategies.

The aim of this study was to figure out the predictors of early postoperative catheter-related bladder discomfort (CRBD) after urological surgery. We designed a prospective observational study in our hospital. Consecutive adult patients undergoing surgery under general anaesthesia or epidural anaesthesia necessitating urinary catheterization were included during a 3-month period. severity of bladder discomfort was assessed on a 4-point scale: (1) no pain, (2) mild pain (revealed only by interviewing the patient), (3) moderate (a spontaneous complaint by the patient of a burning sensation in the urethra and/or an urge to urinate and/or sensation of urethral foreign body without any emotional agitation) and (4) severe discomfort (agitation, loud complaints and attempt to remove the bladder catheter associated with a burning sensation in the urethra). Predictors of CRBD were identified by univariate and multivariate analysis. Totally, 116 patients were included, of which 84.5% had CRBD (mild CRBD: 40.5%; moderate or severe CRBD: 44.0%) at day 1, while 31.9% developed CRBD (mild CRBD: 29.3%; moderate or severe CRBD: 2.6%) at day 3. We evaluated 9 potential forecast factors of CRBD, and univariate Chi-square test showed male gender [OR=2.4, 95%CI (1.1-5.6), P<0.05], abdominal open surgery compared with transurethral surgery [OR=0.3, 95%CI (0.1-0.6), P<0.05], abdominal surgery compared with laparoscopic surgery [OR=3.3, 95%CI (1.2-8.9), P<0.05] and history of catheterization [OR=0.5, 95%CI (0.2-0.9), P<0.05] were independent predictors of moderate or severe CRBD in the patients after surgery. While multivariate logistic regression analysis showed that the abdominal open surgery [EXP(B)=3.074, 95%CI (1.3-7.4), P<0.05] and the history of catheterization [EXP(B)=2.458, 95%CI (1.1-5.9), P<0.05] might contribute more to the occurrence of moderate or severe CRBD. In conclusion, this observational study identified that the type of surgery and the history of catheterization might be predictive factors of moderate and severe CRBD after urological surgery.
