Update on the guideline of guidelines: non-muscle-invasive bladder cancer.

Non-muscle-invasive bladder cancer (NMIBC) is the most common form of bladder cancer, with frequent recurrences and risk of progression. Risk-stratified treatment and surveillance protocols are often used to guide management. In 2017, BJUI reviewed guidelines on NMIBC from four major organizations: the American Urological Association/Society of Urological Oncology, the European Association of Urology, the National Comprehensive Cancer Network, and the National Institute for Health and Care Excellence. The present update will review major changes in the guidelines and broadly summarize new recommendations for treatment of NMIBC in an era of bacillus Calmette-Guérin shortage and immense novel therapy development.

The mechanical stop test and isovolumetric detrusor contractile reserve are associated with immediate spontaneous voiding after transurethral resection of prostate.

PURPOSE: To identify urodynamic factors associated with the mechanical stop test and immediate spontaneous voiding following transurethral resection of prostate (TURP). METHODS: We identified 90 men who underwent TURP over a 12-month period. Forty-three (mean age 68 years) underwent urodynamic evaluation prior to TURP. Isovolumetric detrusor contractile pressure (Piso) was obtained using the mechanical stop test during the voiding phase, and used to calculate detrusor contractile reserve (Pres = Piso - Pdet@Qmax). Primary outcome was spontaneous voiding after TURP. RESULTS: Preoperative catheter-free spontaneous voiding was present in 63% of men (27/43) with a urodynamic (mean ± SD): Qmax 6.2 ± 2.7 mL/s, Pdet@Qmax 102 ± 47 cmH2O, Piso 124 ± 49 cmH2O, Pres 22 ± 16 cmH2O, bladder outlet obstruction index (BOOI) 90 ± 49, and bladder contractility index (BCI) 132 ± 44. The remaining 16 catheter-dependent men demonstrated a urodynamic (mean ± SD): Qmax 3.6 ± 3.3 mL/s, Pdet@Qmax 87 ± 38 cmH2O, Piso 99 ± 51 cmH2O, Pres 10 ± 18 cmH2O, BOOI 82 ± 36, and BCI 106 ± 48. Following TURP, 67% of men voided spontaneously with their first void trial, and in receiver operator analysis of urodynamic measures (Pdet@Qmax, Piso, Pres, BOOI and BCI), only Pres was significantly associated with immediate spontaneous voiding after TURP (threshold Pres ≥ 9 cmH2O, AUC = 0.681, p = 0.035). CONCLUSIONS: In men who underwent TURP, a Pres ≥ 9 cmH2O was associated with immediate spontaneous voiding and may be easily incorporated into the postoperative pathway.

The Effects of Listening to Music on Anxiety, Pain, and Satisfaction during Urodynamic Study: A Randomized Controlled Trial.

INTRODUCTION: To assess the influence of music therapy on perceived anxiety and pain during outpatient urodynamic study (UDS) in a prospective, randomized fashion. METHODS: Between January and December 2018, a total of 70 patients were randomized to either have music therapy (study) or not have (control) in a 1:1 ratio. To the study group, Sufi music was delivered at low tempo. All participants performed the State-Trait Anxiety Inventory evaluation after the procedure and assessed their degree of pain, satisfaction, and willingness to undergo an additional or repeat procedure using the Visual Analog Scale. RESULTS: Patient demographic and baseline characteristics were found to be similar between the 2 groups. Though music did not significantly alleviate pain (4.6 ± 1.2 vs. 4.4 ± 1.7; p = 0.76) and anxiety (47.7 ± 7.75 vs. 46.4 ± 6.5; p = 0.36), it had a positive impact on the patient's willingness to repeat UDS (3.4 ± 1.4 vs. 6.1 ± 1.3; p = 0.005) and provided overall satisfaction (4.6 ± 0.61 vs. 7.2 ± 1.33; p = 0.004). CONCLUSIONS: Music is a practical, harmless, and inexpensive non-pharmacological option that can be adopted during medical and surgical procedures, although according to this present study, listening to music during UDS had no effect on pain and anxiety levels.

Persistent storage symptoms after TURP can be predicted with a nomogram derived from the ice water test.

PURPOSE: To predict the persistence of storage symptoms after transurethral resection of the prostate (TURP) using a nomogram derived from the ice water test (IWT). METHODS: The IWTs of 73 men with lower urinary tract symptoms and prostatic bladder outlet obstruction were retrospectively analyzed. The strength of the detrusor contraction was approximated by using the detrusor gradient of Δpdet /Δt at maximum detrusor pressure and the area under the curve. The parameters were utilized in a nomogram, which facilitated a severity categorization from 1 to 10. Patients with a positive IWT in the categories 1 to 2 were assigned to group A, categories 3 to 4 to group B and categories 5 and higher to group C. After TURP, patients with persisting storage symptoms were offered a botulinum toxin injection. RESULTS: There were 32 patients (44%) with negative and 41 patients (56%) with positive IWTs. Patients with negative IWTs were classified in category 1. Regarding patients with positive IWTs, 14 (34%) were correlated to group A, 14 (34%) to group B, and 13 (32%) to group C. The necessity of a subsequent botulinum toxin injection correlated significantly with a higher nomogram category (P < .001) as well as higher severity categorization (P < .001). In multivariate analysis, the nomogram category was an independent predictor for botulinum toxin injection (P = .002, OR, 6.9, CI, 2.0-23.9). CONCLUSION: The quantification of the detrusor contraction during the IWT allowed stratification of patients in risk categories for persistent storage symptoms after TURP and the potential need for later botulinum toxin injections.

Effectiveness of D-mannose, Hibiscus sabdariffa and Lactobacillus plantarum therapy in prevention of infectious events following urodynamic study.

INTRODUCTION AND AIM: The urodynamic study is an invasive examination that allows a thorough evaluation of the functional activity of the lower urinary tract (bladder, urethra). The execution of urodynamic study exposes the patient to the risk of contracting infections of the lower urinary tract. Prevention of urinary tract infections consists in the avoidance of risk factors and prophylaxis with antimicrobial and non-antimicrobial measures. In this article, we aimed to evaluate the effectiveness of a phytotherapeutic product composed of D-mannose, Hibiscus sabdariffa, and Lactobacillus plantarum in the prevention of infectious events following invasive urodynamic examination. MATERIALS AND METHODS: We selected 100 female consecutive patients (age 19-87 years) that underwent urodynamic invasive procedure. We prescribed 14-day therapy with D-mannose, H. sabdariffa, and L. plantarum to these 100 patients after urodynamic invasive test. After that, we have examined urine cultures and urinary symptoms through telephone interviews and hospital outpatient visits to evaluate the possible presence of urinary tract infections. RESULTS: Urinary tract infections were observed through urine culture in 13% of the selected patients; of the 13 urinary tract infections, 9 were observed in patients with urinary tract recurrent infections in the last year and the other 4 cases were associated with patients with no urinary infection in the last year. Three women reported some urinary symptoms and underwent antibiotic therapy. The other 10 cases were classified as asymptomatic bacteriuria. Three cases were related to patients presenting with pelvic organ prolapse. Eight cases were instead related to significant post-voiding residue (>100). Six patients with urinary tract infection reported constipation in the last year. All patients completed the prescribed therapy due to the affordable price of the product and no side effects have been reported. CONCLUSION: Our study about the administration of D-mannose, H. sabdariffa, and L. plantarum after invasive urodynamic examination underlined how this phytotherapeutic product can reduce the risk of bacteriuria and urinary tract infection in women.

Audiovisual stimulus during urodynamics to provoke detrusor overactivity: A randomized trial.

OBJECTIVE: This study estimated the effect of adding an audiovisual (AV) intervention during urodynamic evaluation (UDE) on increasing detrusor contractions (DO) versus routine UDE testing without AV cues. METHODS: A randomized trial was conducted of women with overactive bladder (OAB) undergoing UDE with and without AV intervention. The AV intervention was a 1-minute video on continuous loop showing common OAB triggers. A continuous running waterfall provided auditory stimulation. The primary outcome was the proportion of patients who had DO on UDE, interpreted by masked clinicians. Secondary outcomes included the number, amplitude, and duration of DO and urinary leakage associated with DO. A sample size of 109 per group was calculated to have 80% power to detect a 20% difference with a significance level of 0.05. RESULTS: In all, 109 women each were randomized to standard UDE and to the AV intervention. There was no difference in the proportion of patients with DO on UDE between the intervention and control groups (35% vs 32%, respectively; P = 0.8). Furthermore, there were no differences between the intervention and control groups in leakage with DO on UDE (24% vs 21%, respectively), mean duration of detrusor contractions (23.9 vs 25.3 s, respectively), or mean maximum detrusor pressure during involuntary contractions (18.1 vs 20.6 cm H2 O, respectively). Clinical severity of OAB symptoms was not associated with the detection of DO or other UDE parameters. CONCLUSIONS: Addition of AV intervention during UDE did not increase the finding of detrusor contractions. The relationship between OAB triggers, urge incontinence, and urodynamic findings remains unclear.

The effects of a heating pad on anxiety, pain, and distress during urodynamic study in the female patients with stress urinary incontinence.

AIMS: Although generally well tolerated, a urodynamic study is an unpleasant and stressful procedure for some patients. This study evaluated the effects of a heating pad on anxiety, pain, and distress during urodynamic studies in female patients with stress urinary incontinence. METHODS: A total of 74 female patients with stress urinary incontinence who underwent a urodynamic study between May 2015 and October 2015 were randomized to either the experimental group using a heating pad (n = 37) or control group (n = 37). In the experimental group, a heating pad was applied on the patient's sacrum during the urodynamic study. All patients completed the State-Trait Anxiety Inventory (20-80) before and after the procedure and assessed their degree of pain and distress after the procedure by the visual analog scale (0-10). Systolic and diastolic blood pressure and pulse rate were also checked before and after the procedure. RESULTS: Demographic characteristics, mean age, procedure duration, pre and post-procedural systolic, and diastolic blood pressures, and pulse rate were statistically similar between the experimental and control groups. The mean State-Trait Anxiety Inventory was significantly lower in the experimental group than in the control group (30.9 ± 7.5 vs 42.5 ± 10.1, P < 0.001). The experimental group showed significantly lower pain and distress scores (Visual Analog Scale, 2.7 ± 1.5, 3.0 ± 1.5) compared with the control group (4.0 ± 1.6, 4.7 ± 2.0, both P < 0.001). CONCLUSIONS: Using a heating pad for female patients with stress urinary incontinence during a urodynamic study is a simple, economical, and effective therapy that enhances patient comfort and decreases anxiety, pain, and distress.

Routine enema before urodynamics has no impact on the quality of abdominal pressure curves: Results of a prospective controlled study.

AIMS: The presence of stools in the rectum might affect the quality of the abdominal pressure curve during filling cystometry, but, to date, no study has evaluated the impact of bowel preparation before urodynamics. We evaluated the influence of a sodium phosphate enema before urodynamics on the quality of the abdominal pressure curve. METHODS: A prospective, controlled, single-blind study was conducted in a single center from May to June 2013. The patients were divided into 2 consecutive groups: patients seen in outpatient clinics during the first 6 weeks (group A) who underwent urodynamics without bowel preparation and patients seen in outpatient clinics during the second 6 weeks (group B) who had a prescription of sodium phosphate enema before urodynamics. The primary endpoint was the quality of the abdominal pressure curve evaluated independently by three physicians who were blinded to the study group. The following data were also collected: age, gender, the presence of a neurological disorder, complicated nature of urodynamics and bother related to preparation for it, assessed using a Likert scale (0 to 10), and the equipment used. A per protocol analysis and an intent-to-treat analysis were conducted. RESULTS: One hundred and thirty-nine patients were included: 54 in group A and 85 in group B. One-third of patients had neurological conditions. 14 patients in group B did not perform their scheduled enema. Thus, 68 patients performed an enema before urodynamics and 71 did not. There was no difference between groups A and B regarding the complicated nature of urodynamics (Likert scale: 3.12 vs. 3.18; P=0.91) or bother related to preparation for it (Likert scale: 3.46 vs. 2.97; P=0.43). In the per protocol analysis, the abdominal pressure curve was considered perfectly interpretable (PI) in 69% of patients who did not receive an enema before urodynamics and in 65% of patients who did (P=0.61). The between-group difference was not statistically significant in intent-to-treat analysis (P=0.99). In patients who did not receive an enema before urodynamics, the only factors statistically associated with better quality of abdominal pressure curves were age <60years (P=0.001) and the urodynamic equipment used (Dantec®>Laborie®; P=0.01). CONCLUSION: In this prospective study, routine enema before urodynamics did not improve the quality of the abdominal pressure curve and did not increase the complicated nature of urodynamics or the bother of preparation for it. LEVEL OF EVIDENCE: 3.

Management of lower urinary tract symptoms associated with benign prostatic hyperplasia in elderly patients with a new diagnostic, therapeutic and care pathway.

INTRODUCTION: Benign prostatic hyperplasia (BPH) resulting in lower urinary tract symptoms (LUTS) is a widespread disease that strongly interferes with the quality of life (QoL) of elderly males. It represents a real clinical and socio-economic problem may be due to the lack of a diagnostic, therapeutic and care pathway (DTCP) tool for LUTS/BPH that considers elderly people population in its whole complexity. The aim of this study was to evaluate the clinical effectiveness of the proposed DTCP LUTS/BPH tool. METHODS: This prospective study was conducted on 278 patients over 75 years old with non-neurogenic LUTS recruited from February to July 2014 by 10 general practitioners (GP) and two assisted sanitary residences (ASR). Only five GPs and one ASR were provided with the complete DTCP LUTS/BPH tool to create two different groups of patients: group A (138 patients) was treated without the aid of the DTCP; group B (140 patients) was treated according to the DTCP. RESULTS: At 1 year of follow-up, the patients of Group B compared with Group A achieved a greater and significant mean reduction in the questionnaires score (International Prostate Symptom Score, Quick prostate test and QoL) linked to a higher increase in the flowmetry parameters (Qmax) and a lower postvoid residual. Furthermore, in Group B compared to Group A, a greater improvement of hydronephrosis, creatinine values and erectile dysfunction (ED) were obtained at 1 year of follow-up. CONCLUSION: The encouraging results obtained from this study are significant and support the use of this diagnostic, therapeutic and care tool (DTCP) as the ideal pathway management for elderly men with LUTS associated to BPH and ED. Further studies with greater number of elderly subjects and long-term follow-up are needed to confirm DTCP utility in the clinical management of LUTS/BPH and ED.

Analytic laboratory performance of a point of care urine culture kit for diagnosis and antibiotic susceptibility testing.

Currently available point-of-care (POC) diagnostic tests for managing urinary tract infections (UTIs) in general practice are limited by poor performance characteristics, and laboratory culture generally provides results only after a few days. This laboratory evaluation compared the analytic performance of the POC UK Flexicult(™) (Statens Serum Institut) (SSI) urinary kit for quantification, identification and antibiotic susceptibility testing and routine UK National Health Service (NHS) urine processing to an advanced urine culture method. Two hundred urine samples routinely submitted to the Public Health Wales Microbiology Laboratory were divided and: (1) analysed by routine NHS microbiological tests as per local laboratory standard operating procedures, (2) inoculated onto the UK Flexicult(™) SSI urinary kit and (3) spiral plated onto Colorex Orientation UTI medium (E&O Laboratories Ltd). The results were evaluated between the NHS and Flexicult(™ )methods, and discordant results were compared to the spiral plating method. The UK Flexicult(™) SSI urinary kit was compared to routine NHS culture for identification of a pure or predominant uropathogen at ≥ 10(5) cfu/mL, with a positive discordancy rate of 13.5% and a negative discordancy rate of 3%. The sensitivity and specificity were 86.7% [95% confidence interval (CI) 73.8-93.7] and 82.6% (95% CI 75.8-87.7), respectively. The UK Flexicult(™) SSI urinary kit was comparable to routine NHS urine processing in identifying microbiologically positive UTIs in this laboratory evaluation. However, the number of false-positive samples could lead to over-prescribing of antibiotics in clinical practice. The Flexicult(™) SSI kit could be useful as a POC test for UTIs in primary care but further pragmatic evaluations are necessary.

CROATIAN UROLOGISTS' CLINICAL PRACTICE AND COMPLIANCE WITH GUIDELINES IN THE MANAGEMENT OF NON-NEUROGENIC MALE LOWER URINARY TRACT SYMPTOMS.

The aim of this study was to assess the Croatian urologists' management of non-neurogenic male lower urinary tract symptoms (LUTS) and their compliance with the European Association of Urology (EAU) guidelines. A cross-sectional survey included 51/179 Croatian urologists. We developed a questionnaire with questions addressing compliance with EAU guidelines. The rate of performing recommended evaluations on the initial assessment of patients with benign prostate hyperplasia (BPH)/LUTS varied from 8.0% (serum creatinine and voiding diary) to 100.0% (physical examination, prostate specific antigen and ultrasound). The international prostate symptom score was performed by 31%, analysis of urine sediment by 83%, urine culture by 53%, and serum creatinine by 8% of surveyed urologists. Only 8% of urologists regularly used bladder diary in patients with symptoms of nocturia. Our results indicated that 97% of urologists preferred alpha blockers as the first choice of treatment; 5-alpha reductase inhibitors (5ARI) were mostly prescribed (84%) in combination with an alpha-blocker, preferably as a continuous treatment, whilst 29% of urologists used to discontinue 5ARI after 1-2 years. Half of the Croatian urologists used antimuscarinics in the treatment of BPH/LUTS and recommended phytotherapeutic drugs in their practice. In conclusion, Croatian urologists do not completely comply with the guidelines available.

Correlation between penile cuff test and pressure-flow study in patients candidates for trans-urethral resection of prostate.

BACKGROUND: Aim of this study was to make a comparison between penile cuff test (PCT) and standard pressure-flow study (PFS) in the preoperative evaluation of patients candidates for trans-urethral resection of prostate (TURP) for benign prostatic obstruction (BPO). METHODS: We enrolled male patients with lower urinary tract symptoms candidates for TURP. Each of them underwent a PCT and a subsequent PFS. A statistical analysis was performed: sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), likelihood ratio and ratio of corrected classified were calculated. Fisher exact test was used to evaluate relationships between PCT and maximal urine flow (Qmax): a p-value < 0.05 was considered statistically significant. RESULTS: We enrolled 48 consecutive patients. Overall, at PCT 31 patients were diagnosed as obstructed and 17 patients as unobstructed. At the subsequent PFS, 21 out of 31 patients diagnosed as obstructed at PCT were confirmed to be obstructed; one was diagnosed as unobstructed; the remaining 9 patients appeared as equivocal. Concerning the 17 patients unobstructed at PCT, all of them were confirmed not to be obstructed at PFS, with 10 equivocal and 7 unobstructed. The rate of correctly classified patients at PCT was 79% (95%-CI 65%-90%). About detecting obstructed patients, PCT showed a SE of 100% and a SP of 63%. The PPV was 68%, while the NPV was 100%. CONCLUSIONS: PCT can be an efficient tool in evaluating patients candidates for TURP. In particular, it showed good reliability in ruling out BPO because of its high NPV, with a high rate of correctly classified patients overall. Further studies on a huger number of patients are needed, including post-operative follow-up as well.

Recent developments in technology for the assessment and management of incontinence.

Urinary incontinence, the leakage of urine, is a common condition, which can have a significant impact on a patient's quality-of-life. Incontinence may arise as a consequence of a weakness of the urinary sphincter or bladder dysfunction, usually over-activity. Incontinence therapies occupy a large proportion of the healthcare budget. As no single device to manage incontinence is appropriate for all situations, a diverse range of products are available on the market and the development of improved products based on fundamental designs has been slow. This review highlights some of the key issues of continence care and describes the current technology and recent developments involved in the diagnosis, assessment and treatment of incontinence, along with the strengths and limitations of these methods. These issues are imperative to address if improved technology is to be developed.

Department of Nephrology at the Medical Faculty, Ss. Cyril and Methodius University, Skopje--creating nephrology protection for the citizens of the Republic of Macedonia.

In January 1975, de facto, the Nephrology Department was founded at the Medical Faculty in Skopje as the first institution of such a type in former Yugoslavia. The Nephrology Department was the driving force for the further development of nephrology in the Republic of Macedonia. D. Hrisoho was the first Director of the Department, and its subsequent Directors were G. Masin, M. Polenakovic, K. Zafirovska and currently A. Sikole. Prior to the establishment of the Nephrology Clinic there had been considerable experience in the diagnosis and treatment of renal patients. The first haemodialysis (HD) in the Republic of Macedonia (RM) was performed in 1959 on a patient with acute renal failure (ARF) using a Kolff-Brigham rotating drum artificial kidney at the Blood Transfusion Institute in Skopje. In 1965 the Renal Unit at the Department of Medicine, Medical Faculty, Skopje obtained a new, modern "Websinger" artificial kidney with a sigma motor pump and possibilities for the use of a disposable Kolff "twin coil" dialyser. Between 1959 and 1971, HD was performed only on patients with ARF. In May 1971, a Unit for Chronic HD was founded at the Renal Unit and the programme of maintenance haemodialysis (MHD) was started with five Stuttgart Fresenius machines and 12 patients dialysed on twin coil dialysers. That was a great incentive for the development of HD in the Republic of Macedonia enforced by the great number of patients with end stage renal disease. Thus in 2007 we have 18 HD centres in the Republic of Macedonia, with 1183 patients. Treatment of the patients with MHD is the greatest success achieved in the Republic of Macedonia in nephrology concerning patients with end stage renal disease. Prior to the treatment with MHD patients were destined to die, whereas now, with this type of treatment, they have a normal life and families. Patients with kidney diseases are examined in outpatients clinics as well as treated in the wards of the Department. All types of vascular accesses, renal biopsies, bone biopsies, kidney ultrasound, plasmapheresis and other investigations are performed every day at the Nephrology Department of the Medical Faculty. On the basis of the results of renal biopsy, a classification of parenchymal renal diseases has been established, as well as appropriate immunosuppressive and other treatments. The nephrology doctrine for primary, secondary and tertiary healthcare has been prepared and has been distributed to all medical centres in the Republic of Macedonia. The first (living donor) renal transplantation was performed in July 1977. Later, living and cadaver donor transplantations were performed, so the Department of Nephrology was complete concerning dialysis and renal transplantation, and it became part of the European centres for diagnosis and therapy of kidney disease. Doctors from the Nephrology Department are among the most productive scientific workers in the Republic of Macedonia and their papers can be found on the internet Pub Med. The Department of Nephrology, together with the Nephrology Association, was the source of knowledge in the area of nephrology and the transfer of knowledge from abroad into Macedonia and vice versa. The Nephrology Association has made a great contribution in the development of nephrology in our country. The most famous European and world nephrologists have participated in the work of our association and have contributed to the development of nephrology not only in Macedonia, but on the Balkans as well.

What are the causes and consequences of bladder overdistension? ICI-RS 2011.

AIMS: To report the outcome of the think tank on prolonged bladder overdistension from the 3rd ICI-RS meeting. METHODS: Prolonged bladder overdistension was discussed after acute urinary retention, its terminology, its prevalence, pathophysiology, and consequences, as well as prophylactic and therapeutic aspects. RESULTS: Acute prolonged bladder overdistension (ApBO) is a consequence of undetected or inadequately treated acute retention, and is mostly due to regional anesthesia, prolonged childbirth, or extensive surgery. Currently, there is no agreed terminology. A primary, temporary neurogenic detrusor dysfunction causing retention is associated with decreased or absent bladder sensation therefore patients do not complain, and management is delayed. Therapeutically, the first intervention is to drain the bladder. Recovery depends on whether reversible or irreversible damage has occurred. There are no good data to support the use of drugs or sacral neuromodulation. Intravesical electrostimulation is the only treatment that has specifically addressed this problem with encouraging results. There are no recent reports on the effect of surgery for myogenic bladder damage. CONCLUSION: ApBO is an important, but often unrecognized medical complication. There is a need for defining the terminology, for studies to record the incidence of different types of bladder overdistension, and to establish management strategies. Apart from clean intermittent self catheterization (CIC) there are no data justifying pharmacological or other therapies. Therefore, prevention is of paramount importance and there is a need to develop and test preventative strategies, which should then be incorporated in surgical registries.

Diagnosis and management of genital ulcers.

Herpes simplex virus infection and syphilis are the most common causes of genital ulcers in the United States. Other infectious causes include chancroid, lymphogranuloma venereum, granuloma inguinale (donovanosis), secondary bacterial infections, and fungi. Noninfectious etiologies, including sexual trauma, psoriasis, Behçet syndrome, and fixed drug eruptions, can also lead to genital ulcers. Although initial treatment of genital ulcers is generally based on clinical presentation, the following tests should be considered in all patients: serologic tests for syphilis and darkfield microscopy or direct fluorescent antibody testing for Treponema pallidum, culture or polymerase chain reaction test for herpes simplex virus, and culture for Haemophilus ducreyi in settings with a high prevalence of chancroid. No pathogen is identified in up to 25 percent of patients with genital ulcers. The first episode of herpes simplex virus infection is usually treated with seven to 10 days of oral acyclovir (five days for recurrent episodes). Famciclovir and valacyclovir are alternative therapies. One dose of intramuscular penicillin G benzathine is recommended to treat genital ulcers caused by primary syphilis. Treatment options for chancroid include a single dose of intramuscular ceftriaxone or oral azithromycin, ciprofloxacin, or erythromycin. Lymphogranuloma venereum and donovanosis are treated with 21 days of oral doxycycline. Treatment of noninfectious causes of genital ulcers varies by etiology, and ranges from topical wound care for ulcers caused by sexual trauma to consideration of subcutaneous pegylated interferon alfa-2a for ulcers caused by Behçet syndrome.

Isoflavones in treating watchful waiting benign prostate hyperplasia: a double-blinded, randomized controlled trial.

OBJECTIVES: This study aims to determine the efficacy and safety of soy isoflavones in controlling the symptoms and signs of lower urinary tract symptoms due to benign prostate hyperplasia (BPH). DESIGN: This was a prospective, randomized, double-blind, placebo-controlled pilot study. SETTING: This trial was conducted at two hospitals in Hong Kong between May 2006 and September 2007. PARTICIPANTS: One hundred and seventy-six (176) participants diagnosed with BPH were recruited from outpatient clinics. Participants with lower urinary tract symptoms were recruited through newspaper and radio interviews, posters placed at government outpatient clinics, and a public seminar offered by the investigators. INTERVENTIONS: Participants were randomly assigned to either intervention (40 mg of isoflavones daily from Soylife 40) or placebo groups in a double-blind fashion. MAIN OUTCOME MEASURES: The primary outcome parameter of peak urine flow rate and the second outcome parameters of postresidual urine volume, lower urinary tract symptoms, testosterone, prostate-specific antigen, quality of life, diet, and safety profile (liver and renal function) were collected. All parameters were assessed at baseline, 6 months, and 12 months in a 12-month study period except testosterone, prostate-specific antigen, and safety profile, which were assessed at baseline and at 12 months. RESULTS: The peak urine flow rate (Qmax), postresidual urine volume, International Prostate Symptoms Scores (IPSS), and 36-Item Short Form Health Survey (SF-36) significantly improved from baseline to the 12th month within both groups. However, when compared between groups, Qmax (p=0.055) and incomplete emptying subscore in IPSS (p=0.05) were marginally/statistically different between the two groups from the 6th to the 12th months, in addition to the general health domain of SF-36 from the baseline to 12th month (p=0.02) and from the 6th month to the 12th month (p=0.055). Isoflavones were generally safe and well tolerated. CONCLUSIONS: This randomized control pilot study showed only slight superiority of isoflavones over placebo over 12 months with otherwise surprising beneficial effects in both groups. Tolerability of isoflavones was excellent; thus it has laid foundations for further studies of isoflavones in BPH with focus on dosage and possible specificity of the effect.

Is the screening method of sacral neuromodulation a prognostic factor for long-term success?

PURPOSE: We evaluated whether there is a difference in long-term outcomes between patients screened with percutaneous nerve evaluation and a first stage tined lead procedure. We also evaluated the outcome in patients who only responded to screening with the tined lead procedure after failed initial percutaneous nerve evaluation. MATERIALS AND METHODS: We evaluated all patients screened for eligibility to receive sacral neuromodulation treatment since the introduction of the tined lead technique in our center in 2002. In May 2009 all implanted patients were asked to maintain a voiding diary to record the effect of sacral neuromodulation on urinary symptoms. Chi-square analysis was used to evaluate differences in the long-term outcomes of the separate screening methods. RESULTS: A total of 92 patients were screened for sacral neuromodulation. Of the 76 patients screened with percutaneous nerve evaluation 35 (46%) met the criteria for permanent implantation. In 11 of the 16 patients (69%) who underwent direct screening with the tined lead procedure permanent stimulators were placed. Of the 41 patients in whom percutaneous nerve evaluation failed and who subsequently underwent screening with tined lead procedure 18 (44%) were implanted with a neurostimulator after a successful response. Statistical analysis showed no difference between screening type and long-term success (p = 0.94). CONCLUSIONS: The first stage tined lead procedure is a more sensitive screening tool than percutaneous nerve evaluation but long-term success seems to be independent of the screening method. Patients in whom percutaneous nerve evaluation initially failed but who responded to prolonged screening the with tined lead procedure appeared to be as successful as those who directly responded to percutaneous nerve evaluation or the tined lead procedure.

Detrusor acontractility in urinary retention: detrusor contractility test as exclusion criteria for sacral neurostimulation.

PURPOSE: Results of sacral neurostimulation in urinary retention are reported in the literature without distinction between the 2 functional disorders causing this condition, detrusor acontractility and functional outlet obstruction. We have suggested a stimulation test to differentiate irreversible bladder myopathy (or complete neurogenic lesion) from potential bladder contractility eligible for sacral neurostimulation. MATERIALS AND METHODS: Direct electrostimulation of the sacral nerves was performed with the patient under general anesthesia. Urodynamic monitoring of bladder (detrusor contractility test) and bowel pressures were used. If no bladder contraction (negative detrusor contractility test) was recorded with positive somatic and bowel responses a irreversible bladder myopathy was supposed and the patient discharged home. If no bladder and no bowel contraction were recorded a complete neurogenic lesion was supposed and the patient was also discharged. RESULTS: Of 96 patients tested with the detrusor contractility test 72 (65%) had no bladder contraction and were excluded from sacral neurostimulation therapy. In this series 15 patients had already been tested with percutaneous nerve evaluation on each S3 nerve with negative results. In 18 cases no bladder and no bowel contraction was evoked (neurogenic lesion). In the remaining 54 cases (bowel but no bladder contraction) a bladder myopathy was supposed. In 24 patients the detrusor contractility test was positive and 12 of these underwent implantation with a permanent device for sacral neurostimulation. CONCLUSIONS: The detrusor contractility test can be considered a reliable tool to rule out detrusor acontractility due to irreversible bladder myopathy or complete neurogenic lesion from sacral neurostimulation.
