Purpose: To describe the association between lower urinary tract symptoms (LUTS) and cardiovascular diseases (CVD), with adjustment for age and other confounders. We were specifically interested in the possible predictive value of LUTS to the incidence of CVD in the future in the general population.

Methods: We performed post hoc analyses using data from the Krimpen study, a large community-based study in the Netherlands.

Background: Although lower urinary tract symptoms (LUTS) seem to be related to cardiovascular disease (CVD) in men, it is unclear whether this relationship is unbiased. In order to investigate this relationship, we used longitudinal data for establishing the possible predictive value of LUTS for the development of CVD in a primary care population.

Methods: We performed a registry study using data from the Registration Network Groningen (RNG).

Objective: Functional urinary incontinence causes considerable morbidity in 8.4% of school-age children, mainly girls. To compare oxybutynin, placebo, and bladder training in overactive bladder (OAB), and cognitive treatment and pelvic floor training in dysfunctional voiding (DV), a multi-center controlled trial was designed, the European Bladder Dysfunction Study.

Objective: To determine the reliability and internal validity of the Hypospadias Objective Penile Evaluation (HOPE)-score, a newly developed scoring system assessing the cosmetic outcome in hypospadias.

Patients And Methods: The HOPE scoring system incorporates all surgically-correctable items: position of meatus, shape of meatus, shape of glans, shape of penile skin and penile axis. Objectivity was established with standardized photographs, anonymously coded patients, independent assessment by a panel, standards for a "normal" penile appearance, reference pictures and assessment of the degree of abnormality.

Introduction: Peyronie's disease (PD) is a fibromatosis of the penis, with a pathology very similar to what is seen in the hand (palmar fascia) in Dupuytren's disease (DD). Recently, we performed a genome-wide association study and identified nine genetic loci containing common variants associated with DD. Seven of these loci mapped within or near genes of the canonical WNT pathway and each locus yielded relatively large odds ratios (ORs) for DD disease status.

Purpose: To assess the outcome of tubularized incised plate (TIP) urethroplasty in conjunction with a dorsal dartos flap for primary proximal penile hypospadias.

Materials And Methods: Forty-nine patients with proximal penile hypospadias underwent a one-stage TIP urethroplasty with single-layer closure using polyglactin suture. A dorsal dartos (subcutaneous) flap, harvested from the dorsal penile shaft was used to cover the neourethra ventrally.

Purpose: Computerized tomography and ultrasound are usually sufficient for preoperative evaluation of renal masses greater than 5 cm. For renal masses less than 5 cm additional histological evaluation could improve diagnosis and treatment decisions. We investigated the concordance between an improved agar microbiopsy technique and conventional cytology for diagnosing renal tumors.

Purpose: An elevated serum prostate-specific antigen (PSA) level cannot distinguish between local-regional recurrences and the presence of distant metastases after treatment with curative intent for prostate cancer. With the advent of salvage treatment such as cryotherapy, it has become important to localize the site of recurrence (local or distant). In this study, the potential of (11)C-choline positron emission tomography (PET) to identify site of recurrence was investigated in patients with rising PSA after external-beam radiotherapy (EBRT).

Objective: We evaluated long-term (> or =12 months) efficacy and safety of tolterodine in children with neurogenic detrusor overactivity.

Subjects And Methods: Subjects successfully completed one of three 12-week, open-label studies and had stable neurologic disease and urodynamic evidence of neurogenic detrusor overactivity requiring intermittent catheterization. Drug formulation and dosing were based on age (4 months-4 years, tolterodine oral solution 0.

The ability to maintain normal continence for urine and stools is not achievable in all children by a certain age. Gaining control of urinary and fecal continence is a complex process, and not all steps and factors involved are fully understood. While normal development of anatomy and physiology are prerequisites to becoming fully continent, anatomic abnormalities, such as bladder exstrophy, epispadias, ectopic ureters, and neurogenic disturbances that can usually be recognized at birth and cause incontinence, will require specialist treatment, not only to restore continence but also to preserve renal function.

Article Synopsis
  • The study aimed to compare how certain medical conditions in kids, like urge syndrome and dysfunctional voiding, respond to different treatments.
  • 97 kids with urge syndrome and 105 with dysfunctional voiding were given treatments and observed through special tests before and after.
  • The results showed that changes in bladder activity didn't really help predict how well the treatments would work, suggesting that standard treatments are enough for most kids.

Objective: To evaluate the long-term tolerability of tolterodine extended release (ER) in children (aged 5-11 yr) with urgency urinary incontinence (UUI).

Methods: This was a multicenter, open-label extension of a 12-wk, double-blind, placebo-controlled study of tolterodine ER. Patients had UUI suggestive of detrusor overactivity (>/=1 diurnal incontinence episode per 24h for >/=5 of 7 d) and >/=6 voids per 24h at baseline and had completed the 12-wk double-blind study.
