Several recent studies have reported the benefits of tubeless percutaneous nephrolithotomy (PNL). Postoperatively, tubeless PNL patients have an indwelling ureteral stent placed, which is often associated with stent-related morbidity. We have performed totally tubeless (tubeless and stentless) PNL in which no nephrostomy tube or ureteral stent is placed postoperatively. We evaluated the safety, effectiveness, and feasibility of totally tubeless PNL.

This study took a retrospective approach to investigate patients with catheter-associated urinary tract infection (CAUTI) over 2 years at a single hospital’s intensive care unit (ICU) to identify meaningful risk factors and causative organisms.

Kidney stones (nephrolithiasis) are a widespread disease. Thus, blocking stone formation and finding new therapeutic methods is an important area of study. Diosmin (a major component of the bile) is known to have antioxidant as well as renoprotective effects. The present investigation aimed to evaluate the effect of diosmin on renal tissue protection in rats with ethylene glycol-induced nephrolithiasis.

Extracorporeal shock wave lithotripsy (ESWL) is a first-line treatment for pediatric urinary stone disease. We aimed to determine the factors affecting the outcome of ESWL for unilateral urinary stones in children.

Infertility affects about 8% to 12% of couples, with male infertility being responsible for about 30% of cases. Sexually transmitted infections (STIs) are known to cause complications of pregnancy and are associated with tubal infertility in females, but the association with male fertility is still controversial. The prevalence of curable STIs has risen to an estimated 448 million a year with the number of people living with human immunodeficiency virus (HIV) at 34 million. This review looks at the evidence available to date, regarding the effect of STIs and male accessory gland infections on markers of male fertility and the evidence that STIs negatively affect sexual functioning, thus adversely affecting the ability to conceive. The review will also cover new developments in the use of medications and fertility treatments as an aid to conception in couples serodiscordant for HIV.

Nocturia is usually considered to be just one of the symptoms included with lower urinary tract symptoms (LUTS) and is treated with therapy based on LUTS. Recent research suggests, however, that nocturia is not merely a simple symptom of LUTS but is a multifactorial condition with many contributing etiological factors. The causes of nocturia can be classified into bladder storage problems, increased urine output, sleep disturbance problems, and other potential diseases. The frequency-volume chart (FVC) is very important in evaluating and diagnosing nocturia. Patients usually record the volume and timing of voids for a period of 1 to 3 days on the FVC. The FVC data can provide information on voiding patterns and clues about the etiology and treatment of nocturia. It is doubtful that alpha-blockers will have clinical significance for treatment because the difference in nocturia episodes between treatment with alpha-blockers and placebo is too small. Antimuscarinics also exert no effect on nocturnal polyuria, and the evidence supporting the efficacy of antimuscarinics for the treatment of nocturia is limited. However, several randomized placebo-controlled trials have shown the efficacy of oral desmopressin in the treatment of adults with nocturia. Short-acting hypnotics may be helpful for patients with sleep disturbances. Although surgical or interventional therapy is not indicated for nocturia, transurethral resection of the prostate appears to confer a greater improvement in benign prostatic hyperplasia symptoms including nocturia. The management of nocturia may require a team approach by making optimal use of multidisciplinary expertise.

Vulvodynia is characterized by chronic vulvar pain caused by sexual intercourse and often results in female sexual dysfunction. Because the causes of vulvodynia are not clear, many patients do not receive optimal treatment. Recently, gabapentin and botulinum toxin A have both been shown to be effective treatments for vulvodynia. In this study, we retrospectively analyzed the clinical outcomes of botulinum toxin A and gabapentin treatment for chronic pain in women with this condition.
