OBJECTIVES: To report our experience with laparoscopic heminephrectomy (LHN) in children with duplex kidneys, highlighting the late outcomes, including anatomical and functional aspects. PATIENTS AND METHODS: We retrospectively analysed the medical records of 17 children (18 renal units) with duplex kidneys who underwent LHN (15) and heminephroureterectomy (three). Before surgery, all patients were evaluated using ultrasonography, voiding cysto-urethrography, computed tomography or magnetic reso

These data show that an activated Wnt/β-catenin pathway and AR expression in prostate cancer are correlated with metastasis and aggressiveness. In addition, the expression of MMP-7 protein, a target of the Wnt/β-catenin pathway, is associated with PSA progression in prostate cancer patients undergoing primary hormone therapy.

Purpose: To examine the impact of lower urinary tract symptoms (LUTS) on health-related quality of life (HRQoL) in Korean men aged ≥40 years. Methods: A population-based, cross-sectional door-to-door survey was conducted among men aged ≥40 years. Individuals with LUTS were defined as men reporting at least one LUTS using 2002 International Continence Society definitions. Structured questionnaires were used to assess several dimensions of HRQoL, including generic health status (EuroQoL-five-dimen

The major hurdle for the clinical application of stem cell therapy is the heterogeneous nature of the isolated cells, which may cause different treatment outcomes. The aim of this study was to examine the effectiveness of mouse clonal bone marrow-derived stem cells (BMSCs) obtained from a single colony by using subfractionation culturing method for erectile function in diabetic animals. Twelve-week-old C57BL/6J mice were divided into four groups: controls, diabetic mice, and diabetic mice treate

The penile length of newborn infants has not changed over the last quarter century in Korea. With normal penile appearance, the AGD ratio and 2:4 digit length ratio are consistent irrespective of birth weight, whereas AGD, digit length, and penile length are significantly smaller in newborns with low birth weight.

There has been a great improvement in height and weight of Korean children owing to economic development over the last 25 years. This study aimed to evaluate the penile length of Korean children today and to compare it with a previous Korean study reported in 1987. The cross-sectional study was conducted with 909 Korean boys aged 0-14 years who had been brought to outpatient clinics of five tertiary hospitals (Busan, Ulsan, and Changwon) between September 2013 and May 2015. The stretched penile

Penile length has increased significantly over the last quarter century. Therefore, it is suggested that novel reference values for penile length in prepubertal Korean children be determined in studies with a larger community-based population in order to diagnose and treat size-related penile disorders.

Penile abscesses are rare, but can develop after trauma, injection therapy, or surgery of the penis, or as an unusual presentation of sexually transmitted diseases. We report a case of penile abscess in a 51-year-old diabetic man, presented 9 days after neglected penile fracture following intracavernosal injection therapy and sexual intercourse. Penile ultrasonography and surgical exploration confirmed the physical examination findings of involvement of the corpus cavernosum. The pus culture fro

The present study aimed to assess the clinicopathological characteristics and the prognosis of renal cell carcinoma (RCC) in children. We retrospectively reviewed the medical records of 11 Korean children (7 boys and 4 girls) undergoing radical nephrectomy for RCC between September 1997 and January 2008 at our institution. Mean age at diagnosis was 12.7 years. The presenting clinical signs and symptoms included gross hematuria (55%), abdominal mass (45%) and abdominal pain (45%). Two (18%) of th

Purpose: Stress is associated with depression, which induces many psychiatric disorders. Serotonin, also known as 5-hydroxytryptamine(5-HT), acts as a biochemical messenger and regulator in the brain. It also mediates several important physiologicalfunctions. Depression is closely associated with an overactive bladder. In the present study, we investigated the effect oftreadmill exercise on stress-induced depression while focusing on the expression of 5-HT 1A (5-HT1A) receptors in the dorsalraph

We investigated the efficacy and tolerability of various anticholinergics in Korean children with non-neurogenic overactive bladder (OAB). A total of 326 children (males:females= 157:169) aged under 18 yr (mean age 7.3±2.6 yr) who were diagnosed with OAB from 2008 to 2011 were retrospectively reviewed. The mean duration of OAB symptoms before anticholinergic treatment was 16.9±19.0 months. The mean duration of medication was 5.6±7.3 months. Urgency urinary incontinence episodes per week decrease

We investigated the efficacy and tolerability of solifenacin 5 mg fixed dose in children with newly diagnosed idiopathic overactive bladder (OAB). A total of 34 children (male/female patients = 16/18) aged under 13 years (mean age: 7.2 ± 2.3; range: 5-12) who were newly diagnosed with OAB from January 2012 to September 2014 were prospectively evaluated with open-label protocol. All patients were treated with solifenacin 5 mg fixed dose once daily for at least 4 weeks. The efficacy and tolerabili

Purpose: Urologic diseases affected by testosterone can be associated with smaller penis size compared to the normal population. We sought to compare penile length in children with unilateral cryptorchidism and normative data from a cohort of healthy Korean boys. Materials and Methods: This study was performed in 259 Korean boys (212, normal cohort; 47, cryptorchidism) aged 6-24 months, each of whom had been brought to an outpatient clinic at one of five tertiary hospitals (Gyeongsangnam-do Prov
