Re: The Effect of Sevoflurane versus Desflurane on Postoperative Catheter-Related Bladder Discomfort in Patients Undergoing Transurethral Excision of a Bladder Tumour: A Randomized Controlled Trial

In this article learn about overactive bladder. What is it, what are the symptoms and who does it affect? Is it the same as stress urinary incontinence?
The Relationship between Diabetes, Diabetes Severity, Diabetes Biomarkers and the Presence of Lower Urinary Tract Symptoms: Findings From the National Health and Nutrition Examination Survey (NHANES)
To characterize the associations between diabetes mellitus (DM) and lower urinary tract symptoms (LUTS). This study focuses on the relationships between specific diabetic characteristics (e.g. severity, biomarkers) and the prevalence of LUTS.

Differences in Cavernosal Artery Parameters According to Different Anatomic Sampling Locations during the Diagnosis of Vascular Erectile Dysfunction Using Duplex Ultrasound
Objective.To establish a standard location for examining penile cavernosal arteries (CAs) using dynamic duplex Doppler ultrasound (PDDU) examination in the diagnosis of non-arterial erectile dysfunction (ED) or arterial insufficiency.Materials and Methods.Two groups of 105 patients each were enrolled. The first group (age 56.3 ± 6.0 years) displayed clinical patterns of arterial insufficiency; the second group (age 35.2 ± 4.7 years) displayed clinical patterns of non-arterial ED. The patients had their peak systolic velocity (PSV), end diastolic velocity (EDV), resistive index (RI = PSV-EDV/PSV x 100) and acceleration time of the cavernosal arteries measured using PDDU at the crura and at the midpoint between the penoscrotal junction and the coronal sulcus (mid penis).
Trans-scrotal Near Infrared Spectroscopy as a Diagnostic Test for Testis Torsion in Pediatric Acute Scrotum: A Prospective Comparison to Gold Standard Diagnostic Test Study
A rapid test for testicular torsion in children may obviate delay for testicular ultrasound. This study assessed testicular tissue percent saturation of oxygen (%StO2) measured by trans-scrotal near-infrared spectroscopy (NIRS) as a diagnostic test for pediatric testicular torsion.
Functional Outcomes Following Nerve-Sparing Prostatectomy Augmented with Seminal Vesicle Sparing Compared to Standard Nerve-Sparing Prostatectomy: Results from a Randomized Controlled Trial
Seminal vesicle sparing may reduce the risk of neurovascular bundle injury and improve functional outcomes after prostatectomy. While several observational studies have reported better functional outcomes following seminal vesicle sparing approaches, evidence from randomized trials is lacking. We conducted a randomized controlled trial comparing functional and cancer control outcomes between nerve-sparing prostatectomy augmented with seminal vesicle sparing (NSP+SVS) and standard nerve-sparing prostatectomy (NSP).
Our study suggests that urinary levels of IL-6 combined with bedside estimation of WBCs is a promising tool to differentiate ABU from a suspected episode of UTI. It also suggests that IL-6 could serve as a marker of treatment or a wait and see approach in suspected UTI cases. The added value of IL-6 in diagnosing UTI was recently tested in a pilot trial in an ABU prone nursing home population, resulting in a 20% reduction in antibiotic treatments without documented side effects (reference 25 in article).
Hooton et al confirmed that colony counts of E. coli as low as 10 to 102 cfu/ml in midstream urine were sensitive for presence of E. coli in catheter urine and, thus, diagnostic for lower UTI in symptomatic women.1 However, in the same study no bacteriuria was found in catheter urine in 26% of symptomatic patients. On the contrary, in women with ABU recurrent symptomatic infections may even be prevented if left untreated.2 Thus, the clinical diagnosis of lower UTI has become much more important and a specific questionnaire was established.
For many years the inappropriate use of antibiotics has been recognized as a major problem, leading to higher health care costs as well as increased antimicrobial resistance.1 On the other hand, no markers predicting the transition from ABU to symptomatic UTI have been available.2 Distinguishing ABU that does not require treatment from symptomatic UTIs may be a key to success for improving antibiotic stewardship (reference 7 in article). A biomarker that could indicate the time to begin antibiotic therapy is highly desirable.
The authors provided an interesting look at the academic profile of the current urologic chairs in the United States.1 I am impressed by the academic productivity as measured by the number of published manuscripts as well as the impact these articles have had in promoting overall urologic scientific discovery. Scientific impact as measured by H-factor was higher for urology chairs compared to other departments such as orthopedic surgery and radiation oncology. It would be interesting if the authors had been able to compare and contrast the temporal changes in the academic and demographic characteristics of chairs over the last several decades.
Accurate risk calculators for predicting the presence of significant prostate cancer at the time of prostate biopsy. Avoiding overdiagnosis and overtreatment is especially important given the increased awareness of prostate biopsy complications and the preventative task force's recommendations on prostate-specific antigen (PSA) screening.1
