A metastatic ureteral tumor successfully treated with multidisciplinary therapy including radiotherapy.

Introduction: Metastatic ureteral tumors are difficult to diagnose pathologically. Treatment is only available for the primary disease, and prognosis is generally poor.

Case Presentation: A 63-year-old patient with a history of gastric cancer presented with asymptomatic right-sided hydronephrosis.

Retroperitoneal abscess due to presenting as femoral pain.

We describe the case of a 65-year-old patient who presented to our hospital with femoral pain. MRI and CT scan revealed a retroperitoneal abscess. We treated him with early surgical drainage and antibiotic treatment.

Prevalence of Sleep Disordered Breathing among Patients with Nocturia at a Urology Clinic.

Objective: We assessed the prevalence of sleep disordered breathing (SDB) and characteristics among patients who visited a urology clinic complaining of nocturia (URO group) and those who visited a sleep apnea (SA) clinic complaining of excessive daytime sleepiness (EDS) (SA group). Additionally, we evaluated the effects of continuous positive airway pressure (CPAP) therapy in the URO group patients with nocturia and SDB resistant to conventional therapy for nocturia.

Methods: Questionnaires were used to assess EDS, nocturia and lower urinary tract symptoms in 34 URO group patients and 49 age-matched SA group patients.

Role of heparan sulfate proteoglycan (syndecan-1) on the renal epithelial cells during calcium oxalate monohydrate crystal attachment.

We have reported that heparan sulfate (HS)/heparan sulfate proteoglycan (HSPG, syndecan-1) expression significantly increased in the rat kidney during calcium oxalate (CaOx) nephrolithiasis. Although the exact role of syndecan still remains unclear, HS/syndecan-1 is thought to have some important role in the CaOx crystal formation. Mardin-Darby canine kidney (MDCK) cells are most commonly used in kidney stone research.
